Throughout the years, one has been judged to be strong enough to cross the field, and the criteria for recognition are particularly uniform: there are no differential locks and how many locks there are. Whether it's an ordinary player or an old off-road gun, it's a theory that without a mechanical lock, it's not really suv。
But the latest exposure of gilly's backbridge double-wire patent has completely escaped decades of mechanical configuration. To put it simply, automatic locking can be achieved without the traditional differential locks, with a combination of a double power machine and an exclusive structure, with no mechanical locks, or even better。
Many people are talking about the fact that, following decades of differential locks, they are really going to be eliminated by the times
I. Traditional ranch: what's the point
In order to understand how subversive the new technologies are, first of all, the significance of the existence of traditional differential chains and why they are essential。
The distance between the right and the right wheel is different, with the outside wheel moving fast and the inside wheel slowly. The effect of the differential is to allow two wheels to turn at different speeds, avoid tire wear and carton, and ensure a normal turn。
But when it comes to bad roads and off-roads, it's fatal。
When vehicles take cross-axis, pits, mudslides, one side of which the wheel is suspended or slides, the power is transported entirely to smaller, empty wheels. The result is that empty wheels are spinning wildly, gripping wheels are not powered, cars are not able to move。
In order to address this problem, the differential locks emerge。
The principle of mechanical differential locks is particularly straightforward, i. E., the forced locking of the right or right half axle through the gear structure and the transformation of the two wheels into synchronized rotations. Wherever it slides, power is imposed on a strong wheel and the vehicle is released。
All these years, all hard-core, four-way suvs have been lifted out of their way by this logic. Three locks, two locks, and back locks have become hard criteria for off-road capability and the default “hard nuclear configuration” of consumers。
Two: the traditional machine is locked
Many thought that the mechanical lock was a perfect solution; indeed, it had been an unsolved shortboard since its birth, but there had been no alternative technology in the past, and people had to accept it。
The first is too complex and heavy a structure。
Mechanical differential locks require a large number of gears, biting structures, transmission axes, electrical control agencies, with large and large parts. The whole structure is placed in the car, which increases the overall weight significantly. The higher the weight, the higher the daily electricity consumption and the higher the fuel consumption, the more comfortable and economical the city will be。
The second problem is that locks are hard and shock strong。
The mechanical locks are rigid bites, opening the locks at a moment, the gears are hard-on, and the body of the car is subject to visible contusions and shocks. Not only is the driving experience poor, but the long-term use also wears and wears transmission systems, semi-axis, tyres, and the ageing of vehicles is faster。
The third problem is that the operational threshold is high and the driver is very selected。
Traditional mechanical locks cannot be opened and are strictly used. It must be slow, straight and smooth, with no locks on the turn, no locks on the speed and no locks on the pavement。
Many newcomers encountered bad roads, either driving behind or behind, or driving indiscriminately, directly injuring the vehicle. This thing in the cross-country, it's being pulled high by mechanical locks。
The fourth issue is high failure rates and high maintenance costs。
Gear bites are a high wear and tear structure, with long-term off-roads, frequent locks, and are prone to wear and tear, acoustic noise and card delay. Post-censorship, oil change and maintenance are cost-effective, and ordinary homeowners do not survive。
Brief summary: mechanical locks are strong, but heavy, energy-intensive, difficult to operate, expensive to keep, intelligent motor vehicles that are not born for the new age。
What exactly is the new patent? Double power achieves self-locking
In the new energy age, the four-drive structure of a car company has completely changed. A large number of high-end land cruiser vehicles have started to use a backbridge double-wire independently driven layout, with each of the left and right wheels being independently powered。
The structure is fast and well controlled, but new problems arise: there are no mechanical speed differentials, power shifts continue to slide, and lock capacity is lacking。
The brand-new post-bridge patent that gilly exposed this time was the brand-new slide lock-out that was designed specifically for a double-wire electric drive structure, leaving out the traditional machine differential lock。
The working logic of the whole system, divided into two daily tasks, is particularly well understood。
The first is normal pavement。
Day-to-day straight-turn, low-speed step, high-speed cruises, smooth roads and unslided wheels. The coupling is loose and does not interfere with the wheel。
The right and right double-wires work on their own, and the wheel is free to travel, bend flexible, without a sense of tug, grinding, carton-free, and the normal vehicle experience with a speed differential is perfectly consistent。
Second, the cross-country slide, single-side wheeling。
When the wheel on one side is suspended, slides, turns up suddenly, and the wheel on the other side is normally on the ground, the internal hydraulic structure of the installation is immediately involved。
Automatically balance the power of the right and right half-axis and automatically complete the locking effect by relying on the resistance of the liquid from the turn differential. The power of the wheel is fast suppressed, and the twist is automatically transferred to the wheel of the ground grab, resulting in rapid escape。
The biggest highlight of the process: full automaticity, no artificial intervention, no mechanical hard bite, millisecond response。
The lock is not opened manually by the driver, the speed of the car is not limited, the road is not picked up, the system identifies itself as sliding, locks itself, deactivates itself and slips without sound。
Iv. Where are the advantages of new technologies compared to the traditional differentials
In the field of off-roads, the whole new structure of gili, compared to the traditional mechanical locks, has structural and generational advantages。
First, the structure is very simple and very light。
Complex gear locking structures have been eliminated, spare parts have been significantly reduced and smaller in size and weight. The problem of “sacrifice for the cause” in traditional land cruisers is addressed once and for all by the lower quality of the whole spring, a more stable and less energy-intensive routine。
Second, the locks were extremely smooth and there was no mechanical shock。
Sliding through liquid resistance is a soft lock, with softness and intervention throughout, without contusion of gear. There was little damage to the half-axis, gearboxes, tyres and higher vehicle durability。
Furthermore, the threshold for crossing the field has been significantly lowered and the newbies can open。
Traditional mechanical locks require experience, operation and road determination. The system is fully intelligent and is subject to smoothing and automatic intervention, with easy access to bad roads, mudslides and pits。
Finally, greater reliability and simpler maintenance。
There are no high-intensity gear structures, fewer core items and lower failure rates for long-term use. Day-to-day maintenance requires only routine inspections, and maintenance costs are much lower than traditional mechanical locking structures。
It also has the advantage of crushing when compared to the current “electronic brake simulation locks”, which are commonly used in electric cars。
The electronic brakes are closed to brakes by friction of the brakes and are prone to heat decay, failure and severe wear and tear for long periods of time. The gleaner set is a smooth physical structure that does not rely on brakes and is more resistant to high temperatures, stability and continuous isolation。
V. A complete transformation of the new energy transition structure, not simply upgrading
Many people think it's just a little improvement, not at all。
During the fuel car age, all four-drive and cross-country logics were built around mechanical gears, mechanical differentials and mechanical locks, without major changes for decades。
By the time of the new energy age, electric power was independent-driven, millisecond-grade, and mechanical structures were heavy, slow, high-depletioned, and no longer kept pace with electric cars。
The greatest significance of the gigi patent is to redefine the bottom structure of the tram crossing。
It proved that the new energy cruiser did not need to follow the three lock logics of the fuel truck and did not have to pile up heavy mechanical structures. A stronger, smoother and more intelligent exit capability can be achieved by using a double power independently driven + smart-limiting structure。
A new trend emerges in the future as new sources of energy move beyond the field: no mechanical locks, electrically controlled smart locks, light quantitative high pass。
In the past, people used to buy cars for “some locks”, then they bought cars for “electrically controlled de-convulsion structures”, and old mechanical standards were slowly replaced by new technologies。
Vi. What practical changes have been made to ordinary car owners when new technologies land
The impact of this patent on the experience of car usage by ordinary consumers is intuitive if it is produced on a large scale。
First, the hard suv is no longer “diverse”。
In the past, hard-to-reachers were either locked but heavy and expensive; they either saved fuel but were not able to escape. The new technology allows daily walk-throughs of comfort and electricity, bad road crossing capabilities online, both for one vehicle and for household and light crossing。
Second, in the future, the four-way threshold for high-end trams has been significantly reduced。
There is no need for complex and expensive mechanical locking parts, so that a double motor vehicle type can carry its own high-strength limit ability to slide out of a trap. In the future, four-drive suvs will be used by middle- and high-end households, which will improve the quality of the cross-country as a whole, and ordinary car owners will be better equipped to adapt。
Thirdly, the use of vehicles is cheaper and more durable。
The simple structure, the smaller wear and tear, the cheaper to maintain, have escaped the “affordable” dilemma of the traditional land cruiser type and have been less expensive for long。
There is still room for growth in new technologies
And, of course, we can't be completely deities of new technologies。
The mechanical differential locks, which have been validated by the market for decades, have been fully proven in terms of the stability of the extremes and the continuous high intensity of the journey。
This whole new structure, currently in the patent phase, will be followed by volume production, road tests, extreme environmental tests and long-term durability certification. It will take time to validate the performance of ultra-high-intensity off-roads, sustained cross-axis escape and extreme road conditions。
It can only be said that it is likely to be able to fend off the day-to-day off-road, to travel lightly, and to replace the traditional back-locks completely; as far as the extremes are concerned, subsequent production performance is required。
Viii. Mechanical differential locks, slowly dropping out of the mainstream stage
We can clearly feel a trend by combing it together。
The mechanical differential locks and three lock myths of the fuel-car age are slowly being broken by new energy power-control technologies。
It is not simply an upgrade of configuration, but a technical trajectories of a four-way system。
The replacement of heavy, old and high-threshold mechanical structures with simpler, lighter, smarter and smoother electrical control structures is the logical direction for the development of new energy sources across the globe。
Over the next few years, the growing number of new energy hard-on suvs in the market will slowly leave the traditional mechanical locks。
The differential locks that everyone used to hold might not disappear at once, but it would not be too late to enter technological history。
