AI Technical Summary

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

Abstract

The invention relates to the technical field of transmission components, in particular to a central cycloidal differential capable of being applied to automobiles. The central cycloidal differential is composed of a planet carrier, at least two A-type planet gears with one ends provided with crank shafts correspondingly, at least two B-type planet gears, at least one A-type wobble gear, an outputgear A and an output gear B. The self rotating axis of each A-type planet gear is fixed to the planet carrier. The self rotating central axis of each A-type planet gear is parallel to the self rotating central axis of the planet carrier. Each A-type planet gear is at least engaged with one B-type planet gear. The journal central axes of cranks on the same stages of the crank shaft on each A-type planet gear are parallel to the self rotating central axis of the gear, and the distances between the journal central axes of the cranks on the same stages of the crank shaft on each A-type planet gearand the self rotating central axis of the gear are equal. The crank shafts on all A-type plane gears are the same in phase position. Journals of cranks on the same stages on each A-type planet gear penetrate through all axis holes in the same A-type oscillating gears.

Description

technical field [0001] The invention relates to the technical field of transmission components, in particular to a central cycloid differential gear that 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. Limited-slip differential, as the name implies, is an ...
