An electronically controlled full-time chain transfer assembly structure

Abstract

The invention discloses an electrically-controlled full-time chained transfer case assembly structure. A differential locking roller is fixed to the bottom of a differential locking support and arranged in a locking rail. A high-low-gear roller is fixed to the bottom of a high-low-gear shifting fork and arranged in a high-low-gear roller track groove. Through matching motion of the rollers, the track groove and the rail, the shifting fork is pushed to enter a target gear, maloperation which is not conducted according to the transfer case gear-shifting sequence by a driver in the manual gear-shifting process is avoided, and quick and accurate gear-shifting operation can be realized. Gear-shifting locking of a differential mechanism is realized through the structure of a sliding gear sleeve; since main torque is transmitted to a planet carrier through a shaft sleeve of a driving shaft, when the differential mechanism is in a differential non-locking state, the sliding gear sleeve does not transmit the main torque, and in the gear shifting process of the differential mechanism, the sliding gear sleeve only achieves the gear shifting effect; as a result, gear shifting is easy, resistance is low, the structural stability of the differential mechanism is guaranteed, and meanwhile the operation stability of the differential mechanism is ensured.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to an electronically controlled full-time chain transfer assembly structure. Background technique [0002] With the development of the automobile market, people's requirements for off-road driving are becoming more and more common, and there are more and more multi-axle drive vehicles. Since the multi-shaft drive car relies on the transfer case to distribute the power output by the transmission to each drive axle, the manual transfer case requires the driver to manually switch the transfer case gear under complex off-road conditions, while taking into account other operating systems of the vehicle. On the one hand, this puts forward extremely high requirements on driving skills, and on the other hand, due to the strict sequence of switching between the gears of the transfer case, manual shifting is prone to misoperation. When the transfer case is shifted and locked, in addition ...

Problems solved by technology

On the one hand, this puts forward extremely high requirements on driving skills. On the other hand, due to the strict sequence of switching between transfer gears, manual shifting is prone to misoperation.

When the transfer case is shifted and locked, in addition to the axial shift force, the shift fork sleeve also needs to transmit torque to the planetary carrier, resulting in greater resistance to the shift operation and more difficult shifting
