Water-cooled motor with adjustable coolant pressure

Abstract

The invention discloses a water-cooled motor with adjustable coolant pressure. The water-cooled motor comprises a motor body, a first rotating shaft, a support, a first gear, a fixing groove, a transition mechanism, a first bearing, a combined cam mechanism, an outer gear, an inner gear, a gear ring, an inner shell, an outer shell, a water pumping mechanism, a water outlet pipe, a pipe body, a bracket, a throttling seat, a sealing head, a push rod, a first spring, a tension pressure sensor, a bottom plate, a servo drive mechanism, a cooling ring groove, cooling fins, a coolant inlet pipe, a coolant outlet pipe and a heat exchanger. The device has a simple structure. A water cooling way is adopted, so that a good cooling effect is achieved. Moreover, a pump and a control system thereof do not need to be arranged separately; high transmission stability and reliability are achieved; and the cooling capacity increases along with the increase of the rotating speed of the first rotating shaft. At the same time, the liquid output pressure can be adjusted to meet the requirement of low-load start-up and make the coolant reach any place of a cavity between an inner shell and the outer shell, thereby increasing the utilization rate of the coolant and improving the cooling effect.

Description

technical field [0001] The invention relates to a motor, in particular to a water-cooled motor with adjustable coolant pressure. Background technique [0002] Drive motors are one of the three core components of new energy vehicles. Compared with traditional industrial motors, drive motors for new energy vehicles have higher technical requirements. Like ordinary motors, new energy drive motors are mainly composed of three parts: stator, rotor, and mechanical structure. However, due to the high power density of the driving motor, the heat generation is more serious, and air cooling or water cooling is often used. Due to the small size of the driving motor, air cooling is limited by the small heat dissipation area, resulting in poor heat dissipation, and water cooling is used. Sometimes it is often necessary to set up an independent water supply system and its control system, resulting in an increase in the complexity of the system. In view of the above defects, it is necess...
