Electronic water pump thrust washer positioning mechanism

Abstract

The invention relates to an electronic water pump thrust washer positioning mechanism. The electronic water pump thrust washer positioning mechanism comprises a motor assembly, the front end of the motor assembly is connected with an impeller rotor assembly, the impeller rotor assembly is connected with a pump cover, the rear end of the motor assembly is connected with a motor rear cover, a controller assembly is arranged between the motor rear cover and the motor assembly, and thrust washers for preventing the impeller rotor assembly from being in frictional contact with the pump cover are distributed between the impeller rotor assembly and the pump cover; and the pump cover is provided with a limiting mechanism for preventing friction between the thrust washers and the pump cover due to rotation of the impeller rotor assembly. According to the electronic water pump thrust washer positioning mechanism, through cooperation of a limiting groove and a clamping block, the thrust washers are limited, and the situation that the service life is affected due to friction between the thrust washers and the pump shell when an impeller rotates at a high speed is prevented.

Description

technical field [0001] The invention relates to the field of electronic water pumps, in particular to an electronic water pump thrust washer positioning mechanism. Background technique [0002] With the development of the automobile industry, the mechanical water pump in the cooling module of the car is gradually replaced by an electronic water pump; when the electronic water pump starts to work after receiving the signal from the driving computer, when the impeller in the electronic water pump is running at high speed, the impeller axial The force will be strung together, causing friction between the impeller and the pump casing, and reducing the service life of the pump; at present, wear-resistant gaskets are often placed between the impeller and the pump casing to prevent direct friction between the impeller and the pump casing. The wear-resistant gasket is driven to rotate and friction occurs between the pump casings, so an electronic water pump thrust gasket positioning...

[0002] With the development of the automobile industry, the mechanical water pump in the cooling module of the automobile is gradually replaced by an electronic water pump; when the electronic water pump starts to work after receiving the signal from the driving computer, when the impeller in the electronic water pump is running at high speed, the impeller axial The force will come out, which will cause friction between the impeller and the pump casing, and reduce the service life of the pump; at present, wear-resistant gaskets are often placed between the impeller and the pump casing to prevent direct friction between the impeller and the pump casing. The wear-resistant gasket is driven to rotate the pump casing to cause friction, so an electronic water pump thrust gasket positioning mechanism is designed to solve the above problems
