Abstract

The present invention relates to a water cooling motor of engineering vehicle. In the technical proposal, a motor shaft is arranged in a motor shell, and is provided with a rotor; the outside of the rotor is provided with a stator which consists of a stator winding and a stator core; and an end cover is arranged at the end of the motor shell. The water cooling motor is characterized in that a cooling water cavity is arranged between the motor shell and the stator core and; the cooling water cavity is connected with a water inlet and a water outlet, which are arranged on the motor shell. The stator core is connected with a peripheral sink; two ends of the peripheral sink are connected with a side plate; and the external surface of the side plate is provided with a sealing groove. The water cooling motor has the advantages of small size, excellent performance of heat dissipation, high cooling speed, low temperature rise, and high security. Moreover, the water cooling motor can effectively prevent the leakage of cooling water, temporarily store the cold water flowing inwards and the hot water flowing outwards, guarantee the circulating use of the cooling water, and satisfy the requirements of electrically driven engineering vehicles.

Description

technical field [0001] The invention relates to a water-cooled motor for engineering vehicles, in particular, it can be widely used in water-cooled motors used on engineering vehicles such as electric drive loaders, excavators, and forklifts. Background technique [0002] The electric transmission of engineering vehicles refers to the transmission system in which the electric motor is driven by electric energy, and the driving wheel is driven by the electric motor. The electric energy can be the electric energy generated by the generator driven by the engine, or the electric energy from the storage battery. For engineering vehicles using electric transmission, due to the limited chassis space, it is generally required to use a motor with a small volume and good heat dissipation performance in order to arrange the drive train reasonably and effectively. However, the conventional air-cooled motor is difficult to be used in such occasions due to its large volume and poor heat ...
