Problems solved by technology
The current limited-slip differentials use electronically controlled multi-plate clutches to achieve locking, but the response speed is relatively slow, and some are realized by purely mechanical worm gears, and the cost is relatively high. When used as a central differential It is also not convenient to set the unequal distribution of the output torque of the front and rear wheels

Description
technical field [0001] The invention relates to a differential, which belongs to the technical field of mechanical transmission components, in particular to a ring gear input central cycloid differential which can be used in automobiles. Background technique [0002] The differential is a mechanical transmission component, which is mostly used to transmit the power output from the gearbox of the car to two or four driving wheels. Due to uneven road surface and vehicle turning, the tracks of the driving wheels are different. If you keep the same speed Rotation will increase the friction between the wheel and the road surface, increasing the driving resistance of the vehicle, so the differential needs to output speed to the wheels according to the different operating conditions of each driving wheel. The traditional differential is mostly helical gear or crown gear structure. [0003] Limited slip differential, the English name is Limited Slip Differential, referred to as LSD....
