Waterproof motor of electric car

Abstract

The invention discloses a waterproof motor of an electric car. The waterproof motor comprises a center shaft, a wheel hub, buckle covers and a stator, wherein the buckle covers are fixedly arranged ontwo sides of the wheel hub; the buckle covers are mounted on the center shaft through bearings; peripheral cylinder-shaped bulge ends are arranged at the ends of the buckle covers; each peripheral cylinder-shaped bulge end is internally provided with a clockwise spiral groove oil seal, an oil storage tank oil seal and an anticlockwise spiral groove oil seal which are arranged in sequence; an oilstorage tank surrounding inner circumference is formed in each oil storage tank oil seal; each oil storage tank is internally provided with a strong magnet material in which a gap is formed and whichcan be automatically filled with grease to form a spherical steel ball; corresponding isolation discs are coaxially arranged at the ends of the outer sides of each clockwise spiral groove oil seal, the corresponding oil storage tank oil seal and the corresponding anticlockwise spiral groove oil seal; grease leak-proof sleeves are coaxially and tightly sleeved on the outer peripheries of the peripheral cylinder-shaped bulge ends; continuous spiral bulge parts are arranged at the end of the inner side of each grease leak-proof sleeve; continuous spiral oil storage tanks are formed between the spiral bulge parts; an embedded stainless steel material is arranged on the spiral bulge parts to form sheet one-way non-return doors. The waterproof motor is scientific in design, and the technical problem that water enters into the interior of the motor is solved effectively.

Description

[0001] Technical field [0002] The invention relates to the technical field of electric vehicle motors, in particular to a waterproof motor for electric vehicles. Background technique [0003] my country is a big producer and consumer of electric vehicles. In order to prevent the design defect of short circuit caused by water leakage during the use of electric vehicle motors, rubber sealing rings are generally installed on the rotating shaft of electric vehicle motors to prevent water leakage and sealing problems of electric vehicles. However, electric vehicle motors During use, the rubber sealing ring and the central shaft rub against and the gap becomes too large, especially if the electric vehicle motor encounters rain, the rainwater will enter the interior from the joint gap of the motor sealing ring assembly, destroying the oil film of the bearing and making the bearing abnormal. Working and consuming electric energy, when it rains into the motor, the main parts will rust ...

Problems solved by technology

[0003] my country is a big producer and consumer of electric vehicles. In order to prevent the design defect of short circuit caused by water leakage during the use of electric vehicle motors, rubber sealing rings are generally installed on the rotating shaft of electric vehicle motors to prevent water leakage and sealing problems of electric vehicles. However, electric vehicle motors During use, the rubber sealing ring and the central shaft rub against and the gap becomes too large, especially if the electric vehicle motor encounters rain, the rainwater will enter the interior from the joint gap of the motor sealing ring assembly, destroying the oil film of the bearing and making the bearing abnormal. Working and consuming electric energy, when it rains into the inside of the motor, it will rust the main parts and fail prematurely, because the coil inside the motor will cause a short circuit and burn out when it encounters water, so that the motor cannot be used normally
