Abstract

Disclosed is a high-efficiency electric steering pump. An output shaft of the steering pump and an output shaft of a motor are of a coaxial structure. An oil feeding side plate, a stator and an oil drainage side plate are in through connection with a pump body through a positioning pin. One end of the pump body is provided with a pump cover. A rotor is installed in an inner hole of the stator. A blade is installed in a slot hole of the rotor. One end of a sliding valve is provided with a spring. A cone valve is arranged inside the sliding valve. A spring is arranged between one end of the cone valve and the sliding valve. The end, provided with the spring, of the sliding valve is connected with an oil drainage connector. According to the high-efficiency steering pump, a traditional transfer way of coupling connection of a coupling, a gear and the like is canceled, the output shaft of the steering pump and the output shaft of the motor are designed as one shaft, one end of the shaft is assembled to the motor, and the other end of the shaft is assembled to the steering pump. When a motor shaft is rotated, internal components of the steering pump are directly and synchronously driven to operate, work of the steering pump is achieved, and no transfer loss is caused in the operation. Besides the design characteristic that transfer efficiency is improved, the structure inside the steering pump, except for design parts of a bearing and a check ring is simplified.

Description

technical field [0001] The invention relates to the technical field of electromechanical transmission and hydraulic transmission, in particular to the technical field of automobile hydraulic power steering pump. Background technique [0002] Traditional automobile steering pumps have been using transmission methods such as pulleys, gears, and couplings for many years. Due to the weight of the transmission parts such as pulleys and gears when they rotate, the moment of inertia is generated during rotation, which has a large loss in transmission efficiency, and due to coupling The working noise such as the noise generated by the transmission of parts such as gear transmission meshing is also relatively large. With the serious environmental pollution and the rise of new energy electric buses, the demand for electrohydraulic steering pumps is increasing year by year. Under the requirements of energy saving and low noise operation of new energy vehicles, how to improve transmissi...
