Problems solved by technology

[0002] At present, the structure of the steel ring and motor casing assembly of electric motorcycles used in China is: the steel ring has two kinds of aluminum alloy steel ring and plate steel ring, and the plate steel ring is rolled by steel plate, and the connecting steel ring The radial plate between the ring and the motor casing is stamped as a whole. The motor casing is made of poured steel, and the end covers of the bearing brackets are covered at both ends of the motor casing. The main problem is that the low carbon content required by pouring steel is difficult to guarantee, the utilization rate of the magnetic circuit generated in this way is not good enough, the power of the motor is lost, and the service life is affected

Embodiment Construction

[0012] exist figure 1 , figure 2 Among them, five spoke plates (3) are evenly distributed and welded on the steel ring (4), the motor housing and one end cover are integrated, and the open end of the motor housing (6) has an everted flange, and the spoke plates (3) and the flange of the motor housing (6) are fixed with bolts (1), spring washers (2) and nuts (5). The motor casing (6) is formed by stretching a low-carbon steel plate, and the radial plate (3) is formed by stamping a steel plate. At the open end of the motor housing (6), a bearing support end cover or a brake drum can be installed as required.

[0013] Such as figure 1 , figure 2 As shown, the steel plate is first spun into a steel ring (4), the steel plate is stamped into a spoke plate (3), and then the spoke plate (3) is welded to the inner ring of the steel ring (4), and the motor housing (6 ) The flange plate and the spoke plate (3) are fastened with bolts (1), spring washers (2) and nuts (5), and the m...

Abstract

An assemblage of rim and motor casing for electric motorcycle is composed of steel rim and web consisting of several web units and fixed to the casing of motor. Its manufacture includes such steps as rolling steel plate to form steel rim, punching on steel plate to obtain web units, welding the web units to steel rim, and connecting the flange of motor casing with web via screw bolts.

Description

Technical field [0001] The invention relates to the technical field of electric motorcycle accessories, in particular to an electric motorcycle steel ring and motor casing assembly and a manufacturing method. Background technique [0002] At present, the structure of the steel ring and motor casing assembly of electric motorcycles used in China is: the steel ring has two kinds of aluminum alloy steel ring and plate steel ring, and the plate steel ring is rolled by steel plate, and the connecting steel ring The radial plate between the ring and the motor casing is stamped as a whole. The motor casing is made of poured steel, and the end covers of the bearing brackets are covered at both ends of the motor casing. The main problem is that the low carbon content required by pouring steel is difficult to guarantee, the utilization rate of the magnetic circuit of the magnetic field generated in this way is not good enough, the power of the motor is lost, and the service life is af...
