Abstract

The invention provides an integrated variable-speed driver of an electric automobile. The driver structurally comprises a machine body, a connecting cover, a rotating shaft and a shaft sleeve, the left end of the machine body is fixedly connected with the right end of the connecting cover in an embedded mode, the right end of the rotating shaft is connected with the left end of the machine body in a welded mode, and the right end of the shaft sleeve is fixedly installed at the left end of the connecting cover in an embedded mode. The machine body comprises a bearing, an electromagnetic coil, fan blades, a connecting shaft, a heat dissipation cover, a rotor and a sealing wall, the inner side of the bearing is connected with the outer side of a rotating shaft in an interference fit mode, the outer side of the electromagnetic coil is connected with the inner side of the sealing wall in a welded mode, and the inner sides of the fan blades are fixedly connected with the outer side of the connecting shaft in an embedded mode. When the engine oil is caked on the cleaning rod in the ventilation plate, through vibration generated by rotation of the rotor in the electromagnetic coil, the vibration borne by the connecting block is conveyed into the vibration force plate from the conduction plate, the stress plate is impacted and extruded inwards through vibration, and cakes are crushed through the impact block in the pressing block so that the cakes are prevented from being blocked in the ventilation opening.

Description

technical field [0001] The invention belongs to the technical field of key components of automobiles, and more specifically relates to an integrated variable speed drive for electric vehicles. Background technique [0002] The variable-speed drive motor is one of the main core components of electric vehicles. The central control system conducts conductive pressure on the stator, so that the internal electromagnetic coil is energized and has a physical reaction with the permanent magnet in the rotor, so that the permanent magnet drives the rotating shaft in the electromagnetic coil. Rotate, and can regulate the rotation speed of the rotating shaft by controlling the magnitude of the voltage, so as to realize the speed change function of the drive motor to the car. [0003] Because the driving motor needs to be maintained with oil when it is in use, and the oil will burn at high temperature to form sludge, and the sludge contains iron filings from gear wear and carbon deposits...
