A fully automatic differential transmission

Abstract

The present invention provides a fully automatic differential transmission device, which includes a differential device and an output shaft assembly, the output shaft assembly includes a first output half shaft and a second output half shaft, and the differential device includes a first The side gear and the second side gear, the differential device is connected with a symmetrically arranged differential lock gear clutch device, the differential device includes a driven gear plate, and the two ends of the driven gear plate are respectively The first side gear cover and the second side gear cover are provided, and the differential locking gear clutch device includes an elastic reset part and a clutch part, and the clutch part includes a fixed chainring and a movable chainring, which are automatically driven by the output torque. Adjust the working state of the differential lock so that the wheels on both sides touch the ground at the same time, which greatly increases the grip, and the switching speed is fast to avoid accidents. The torque can be effectively increased through the differential lock tooth separation device, and the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a fully automatic differential transmission device. Background technique [0002] The automobile differential is a mechanism that enables the left and right driving wheels to rotate at different speeds. It is mainly composed of a left side gear, a right side gear, two planetary gears and a wheel carrier. The traditional function is to achieve turning or driving on uneven roads. When driving, the left and right wheels rotate at different speeds, so as to ensure that the driving wheels on both sides maintain power output at all times. However, although the traditional differential can allow the left and right wheels to rotate at different speeds, when one of the left and right wheels is idling, the other wheel on a good road cannot get enough torque, so the car loses its normal driving ability. ability, so when this happens, the differential lock can connect the two wheels together, and ...

Problems solved by technology

[0003] The mainstream differential locks currently used are manual mechanical differential locks and Eaton differential locks. Although the manual mechanical differential locks can realize the complete mechanical combination of the power of the two half shafts, they can only be used in bad road conditions and extreme conditions. It is widely used and needs to be switched manually. Although the Eaton differential lock will automatically lock the differential, it must wait until the speed difference appears before it can work, and the response speed is slightly slow.
