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

The invention relates to a planetary composite gear ring output cycloid differential mechanism. The planetary composite gear ring output cycloid differential mechanism consists of a housing, a crankshaft, a crankshaft gear, one or more planetary gears, one or more swinging gears, an output wheel A and an output wheel B, wherein the crankshaft, the crankshaft gear, the output wheel A, the output wheel B and an autorotation shaft center of the housing are coaxial; the output wheel A comprises an inner gear ring which is fixed in the circumferential direction of the output wheel A and meshed witheach swinging gear; the output wheel B also comprises an inner gear ring which is fixed in the circumferential direction of the output wheel B and meshed with each planetary gear; the crankshaft is fixed on the crankshaft gear in the circumferential direction; each level of bellcrank of the crankshaft penetrates through the central shaft hole of the corresponding swinging gear; the housing comprises a pin shaft which is fixed in the circumferential direction of the housing; the pin shaft of the housing penetrates through corresponding pin shaft holes in each swinging gear; the autorotation shafts of the planetary gears are fixed on the housing in the circumferential direction and the radial direction; and the planetary gears are meshed with the crankshaft gear.
Description
technical field [0001] The invention relates to a differential, which belongs to the technical field of mechanical transmission components, in particular to a planetary compound ring gear output 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, referre...
