Abstract

The invention discloses an electric hydraulic power steering pump assembly. The electric hydraulic power steering pump assembly comprises a motor, a controller and a driving support. The driving support comprises a copper conductor and an outer insulation sleeve wrapping the copper conductor. The copper conductor is provided with first copper sheets connected with a motor stator of the motor and second copper sheets connected with the controller. The first copper sheets and the second copper sheets stretch out of the outer insulation sleeve. According to the electric hydraulic power steering pump assembly, the driving support connected with the motor stator and the controller is arranged, so that a traditional wiring harness is replaced, the driving support is used for connecting the motor and the controller, the driving support is composed of the copper conductor with good conductivity and the outer insulation sleeve, the advantages of being not prone to ageing and not prone to short circuit are achieved, and the connecting reliability and safety of the motor and the controller are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of vehicle steering systems, in particular, the invention relates to an electric hydraulic power steering pump assembly. Background technique [0002] Electric power steering has many advantages such as energy saving, environmental protection, and safety, and is currently a research hotspot in the electrification of power steering. [0003] The electro-hydraulic power steering pump is an integral structure composed of a motor, a support and a hydraulic pump. The stator of the motor is installed on the casing of the support, and the motor shaft is inserted into the bearing hole in the casing and connected to the hydraulic pump. [0004] At present, the electric motor of the electrohydraulic power steering pump and its corresponding controller and power supply are all connected through a wire harness. The controller issues instructions to the motor to control the speed of the motor, and the wire harness is pro...
