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

Embodiment 1
[0020] Example 1, such as Figure 1~Figure 3 As shown, the planetary composite ring gear is input to the central cycloid differential, which is composed of a housing, a crankshaft, two swing gears, an input wheel A, 4 planetary gears, an output wheel B, a crankshaft gear and a planet carrier; the crankshaft, The rotation axes of input wheel A, output wheel B, crankshaft gear, planet carrier and housing are coaxial, and the crankshaft passes through the central shaft hole of the crankshaft gear through the oblate shaft to achieve coaxial and circumferential fixation. The sleeve is embedded in the input wheel A and the output wheel B; the crankshaft gear and the four planetary gears all use involute external spur gears with the same modulus. It meshes with 4 planetary gears; the housing includes a part processed with 8 pin shafts, the pin shafts of this part pass through the corresponding pin shaft holes on the two swing gears, and the part is circumferentially fixed with the ho...

Description
technical field [0001] The invention relates to a differential gear, which belongs to the technical field of mechanical transmission components, in particular to a planetary compound ring gear input central cycloid differential gear 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 Diff...
