Abstract

The invention discloses a direct-current brushless electro-hydraulic power steering pump and a control method thereof of a new energy passenger car. The technical problem of too high temperature of oil liquid of existing steering pumps is solved. The direct-current brushless electro-hydraulic power steering pump of the new energy passenger car comprises a steering pump assembly, a direct-current brushless motor and a steering controller. An output shaft of the direct-current brushless motor is connected with a pump shaft of the steering pump assembly through an insulation transmission device. The insulation transmission device comprises a transmission connection block and a connection block insulation sleeve which are connected to the pump shaft in a sleeving mode sequentially from inside to outside and connected into a whole. The transmission connection block and the pump shaft transmit torque fixedly in the radial direction, and the connection block insulation sleeve and the output shaft of a steering motor assembly transmit torque fixedly in the radial direction. A heat dissipation cover with an opening is disposed on the steering pump assembly, the steering controller is connected with an angle sensor which detects the rotation angle of a passenger car steering wheel, and the steering controller controls the rotation speed of the steering motor assembly in a closed-loop mode according to an angle signal.

Description

technical field [0001] The invention relates to an electric pump, in particular to a DC brushless electro-hydraulic power steering pump for a new energy passenger car and a control method thereof. Background technique [0002] At present, the traditional automotive hydraulic power steering vane pump, the whole steering pump is installed on the engine interface through gears or splines, the whole steering pump is installed on the engine interface through gears or splines, and the speed of the steering pump changes with the change of the engine , the speed range of the steering pump is relatively high, and the flow of the output oil of the steering pump is only controlled by the speed of the blades of the steering pump, so that the size of the steering power cannot be controlled, and the running time of the urban bus is long, because the steering pump works at high speed for a long time , due to the large useless work generated by the internal overflow, the oil temperature of ...
