What is the difference between a mechanical torque-sensing limited-slip differential and a Torsen differential?
1 Answers
The differences between a mechanical torque-sensing limited-slip differential and a Torsen differential are as follows: 1. Different nature: Torsen differential: When the differential torque inside the differential is small, it functions as a differential. When the differential torque becomes too large, the differential automatically locks, effectively improving the vehicle's off-road capability. Off-road vehicles with only electronic limited-slip are suitable for snowy or icy roads and light off-roading but not for extreme off-roading. 2. Different principles: Torsen differential principle: It uses the high internal friction torque (Mr) of the worm gear transmission pair for torque distribution. The internal friction torque (mr) depends on the relative speed of the output shafts at both ends. When the relative speed difference between the two output shafts is small, the friction force of the worm driven by the rear worm gear is also small. The differential spur gear absorbs the speed difference between the two output shafts. The mechanical limited-slip differential prevents tire slippage through mechanical principles, distributing driving force evenly to all four tires. Such off-road vehicles can handle high-intensity and long-duration off-roading and are among the most professional off-road vehicles. 3. Different meanings: The Torsen differential achieves constant, continuous torque control management, operates continuously without delay, but does not interfere with the adjustment of total torque output, resulting in no torque loss. There are many working principles for mechanical limited-slip differentials, the most common being differential locks—front, rear, and center. Vehicles with three locks include the Jeep Wrangler, Toyota Land Cruiser, Mercedes-Benz M-Class and G-Class, Land Rover Range Rover, Beijing Jeep, and Great Wall Haval H9, among others.
