Abstract

The invention discloses a steering gear of an automobile. The steering gear comprises a steering gear body and a throttle valve. An oil inlet hole and an oil outlet hole are formed in the steering gear body, the throttle valve comprises an adjusting shell, a pushing assembly, an adjusting valve and a spring, the pushing assembly is configured in the adjusting shell, an oil inlet delivery hole and an oil outlet delivery hole are formed in the adjusting shell, the oil inlet delivery hole is communicated with the oil outlet hole, the adjusting valve is positioned in a communication channel between the oil inlet delivery hole and the oil outlet delivery hole, and two ends of the adjusting valve are respectively abutted to the pushing assembly and the spring. The invention further provides a keyless entry starting method for the automobile. The steering gear of the automobile and the keyless entry starting method have the advantage that steering fluctuation and steering noise can be prevented.

Description

technical field [0001] The invention relates to the technical field of automobile parts, in particular to an automobile steering gear. Background technique [0002] With the rapid development of economy, automobiles have become an indispensable means of transportation in people's lives. The car steering gear is an important part of the car, its main function is to change the driving direction of the car and keep the car running in a straight line. The steering gear is the actuator of the hydraulic power steering system. It mainly converts the rotation of the steering wheel into the linear motion of the rack shaft or the swing of the steering rocker arm, reduces the speed of movement, increases the steering torque and changes the direction of rotation of the steering torque. [0003] A kind of existing rack and pinion automobile steering gear mainly comprises input shaft assembly, housing and rack, and input shaft assembly is arranged on the housing, and rack is penetrated i...
