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 planet reduction box (100); the motor shaft is a hollow shaft; the planet reduction box is provided with a sun gear, a planet carrier and a tooth ring; the motor shaft is connected with the sun gear; one end of the planet carrier is connected with the steering oil pump, and the other end penetrates the motor shaft and is connected with the inflator through an electromagnetic clutch (50); the controller is used for controlling the electromagnetic clutch to connect or disconnect. By using the scheme, the inflator, the motor, the planet reduction box and the steering oil pump are coaxially arranged; the planet reduction box is arranged, so the whole structure is more compact, and smaller in radial volume; in addition, the planet reduction box speed ratio can be very big, so the motor with higher rotating speed and smaller volume can be employed, thus reducing cost.

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 combination system of vehicle braking and steering, including an air compressor, a mo...
