Limited-slip differential

When driving on a rough road or in a turn, the driving wheels travel a different path, which leads to additional load on the tires and transmission parts (for example, the pinion & gear set). This circumstance significantly increases their wear and degrades handling. In an era of low speeds and no roads this problem did not cause drivers much concern, and the solid driving axle only increased the vehicle's cross-country capability.

However, the technique improved, the speed increased, which led to the need to untie the driving wheels. Such a device that allows the wheels to rotate at different speeds served as a differential - a planetary mechanism that distributes the torque equally between the half-axles.

However, despite the increase in stability and handling of the car, the differential significantly reduced its passability. It is the factory LADA differential that suffers from such a disadvantage. This disadvantage arose from the fact that the amount of torque was set by the wheel having the worst grip on the road. By this reason, one wheel started to slip, and the second just stopped.

The use of a manual differential lock could not solve this problem, since such a device was only suitable for overcoming difficult road sections and required constant attention from the driver.

The need to automatically lock differentials has led to the creation of various designs of self-locking differentials (differentials of increased friction). These differentials do not require additional actions from the driver and even compensate for some errors.

Self-locking screw-type differentials (Torsen) are the most common when tuning serial cars. This is due to their high resource and lack of problems during installation. Thanks to their relatively simple design, these differentials are available and require almost no maintenance.

The disadvantage of most differential block designs is the occurrence of short-term peak loads that appear when the lock is turned on. A special feature of the screw lock is a smooth on-off process, which prevents increased wear of the transmission. In addition, when the screw lock is activated, no additional shock force is transmitted to the steering wheel (which is typical when installing disk locks on front-wheel drive cars).

The installation of a self-locking screw differential significantly increases the vehicle's passability and stability on a slippery road. Thanks to the optimal distribution of torque between the driving wheels, the wheel that is skidding on a slippery road is unloaded, and the wheel that has a better grip on the road surface receives additional torque. The car with a screw lock accelerates faster on ice and dense snow, is easier to manage in turns and prevents the failure of the driving wheels when starting abruptly on the asphalt.

For an even more comfortable ride, a preload clutch is installed in the differential lock system, which equalizes the lock operation and reduces the load on the car's transmission. The preload value indicates the minimum torque applied to the wheel, regardless of its position on the road. The optimal preload value depends on the operating conditions of the car: a smaller preload makes it easier to drive the car on sharp turns, and a larger one increases the cross - country ability on a bad road. However, only experienced professionals can take into account all the nuances of the car design, driving style and road (or off-road) pavement. These are the specialists of LADA Moscow, who when installing the differential lock will set (at the request of the client) the most appropriate preload value (for driving under normal conditions, the preload value is usually set to 4 kg).

Due to the design features of self-locking screw differentials, their manufacture requires high accuracy, and high mechanical loads imply a large margin of safety of components.

The kits offered by LADA Moscow for the Assembly of screw differentials (LADA LSD) of increased friction are manufactured in the factory on the most modern equipment. Thanks to strict control of the entire production cycle, these self-locking differentials are highly reliable and have a long service life. Finishing control and assembly of screw differentials are carried out by specialists of the http://ladamoscow.com/, which provides an additional guarantee of high performance and safety on the road.
