ELECTRIC LUBRICATING PUMP FOR VEHICLE AXLE

WIPO Patent Application WO/2021/208405

A1

An electric lubricating pump for a vehicle axle, comprising a lubricating pump body (1). A motor housing (4), a first pump cover (12), and a second pump cover (18) are fixedly mounted on the outer surface of the lubricating pump body (1). By means of the cooperative use of a control block (13), a pressure sensor, and a temperature sensor that are provided, the amount of a pressed lubricating oil can be effectively adjusted, so that the purpose that the utilization rate of the lubricating oil is maximized is achieved, the utilization efficiency of the lubricating oil is improved, and the service life of an oil suction cavity and that of an oil pressing cavity can be prolonged. An inner rotor (15) and an outer rotor (17) both use a permanent magnet structure, without needing an exciter. The inner rotor (15) and the outer rotor (17) are embedded into the motor housing (4), and thus, the space can be effectively reduced. The motor and the pump body are integrated and there is no a coupling joint, thereby reducing transmission loss and improving the transmission efficiency.
