Problems solved by technology

Although the anti-slope rolling device can effectively prevent the car from slipping back when starting on a slope through the cooperation of the rollers in the clutch, the cross block and the brake drum; but the structure of the anti-slope rolling device is complicated. , the processing of mechanical components is difficult, and the reliability of operation is poor, the loss of transmission torque is large, and mechanical failures are prone to occur, resulting in increased maintenance costs and poor customer satisfaction

Abstract

The invention relates to a vehicle movement direction control mechanism used for controlling a movement direction when a vehicle starts on a ramp. The vehicle movement direction control mechanism comprises a differential housing, two transmission housings, two electromagnetic valves and two one-way clutches, the transmission housings, the electromagnetic valves and the one-way clutches are respectively and symmetrically disposed on the left side and the right side of the differential housing, a valve seat and a valve core of each electromagnetic valve are both of a sleeve structure, the valve seat of each electromagnetic valve is fixedly assembled with the transmission housing on the same side, the valve core of each electromagnetic valve is fixedly assembled with the one-way clutch on the same side, and the transmission housings are sleeved outside the differential housing. The vehicle movement direction control mechanism has the advantages of simple structure and convenience in operation, vehicle rolling when the vehicle starts on the ramp can be prevented, a reliable parking brake function can be realized, and safety performance of the vehicle is improved.

Description

technical field [0001] The invention relates to a movement direction control mechanism of an automobile, in particular to a movement direction control mechanism for preventing the automobile from slipping back when starting on a slope, and belongs to the technical field of vehicle transmission devices. Background technique [0002] The car often encounters the situation of starting on a slope during use. Because there is a component force of the body weight downward along the slope when parking on the slope, the vehicle is in the parking brake state at this time. When the vehicle starts on a slope, the driver needs to step on the clutch first to interrupt the power transmission of the vehicle, and then manipulate the shift handle to drive the shift actuator through the cable or rod connected to the shift handle to complete the neutral gear and forward gear. Switch, then step on the accelerator and slowly release the clutch to realize the gradual output of engine power. When ...
