Abstract

The invention provides a vehicle braking and steering combined system comprising an inflator (10), a motor (20), a steering oil pump (30), a controller (40) and a reduction box (100); the motor shaft of the motor (20) is connected with the input shaft of the reduction box; the first output shaft of the reduction box is connected with the steering oil pump; the second output shaft of the reduction box is connected with the inflator through an electromagnetic clutch (50); the controller is used for controlling the electromagnetic clutch to connector or disconnect. By using said structure, the reduction box has two output shafts, so motor power density can be improved, thus reducing motor volume, and reducing cost; in addition, two output shafts of the reduction box are respectively designed with different reduction ratios according to requirements of the inflator and the steering oil pump, i.e., the rotating speed of the motor, the steering oil pump and the inflator can be flexibly designed, and reduction ratios of the two output shafts can be coupled; the whole combined system is compact in structure, small in noises, and high in transmission efficiency and reliability.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a combination system of braking and steering of a vehicle. Background technique [0002] In existing vehicles, especially electric vehicles, two motors are used to drive the air compressor and the steering oil pump respectively. The air compressor is used to provide air pressure for the vehicle braking system, and the steering oil pump provides power for the vehicle steering system. . In this way, more layout space on the chassis will be occupied, and the weight of the whole vehicle and the manufacturing cost will also be increased. Contents of the invention [0003] The object of the present invention is to provide a combined braking and steering system of a vehicle, which can solve the related problems in the prior art. [0004] In order to achieve the above object, the present invention provides a vehicle braking and steering combined system, including an air compressor, a motor, a...
