Embodiment Construction

[0021] Further describe the technical scheme of the present invention below in conjunction with accompanying drawing:

[0022] A method for connecting a drive system of a pure electric vehicle, comprising the following steps:

[0023] A. Machining motor rotor spindle 1

[0024] The positioning adopts the double-top clamping method. Use the chuck thimble and the tailstock thimble to support the rotor spindle 1 of the processing motor, and adjust the height of the rotor spindle 1 of the processing motor by adjusting the top of the tailstock to perform alignment and positioning, and then clamp it with jaws The motor rotor main shaft 1 is processed by rotating to detect the axial movement of the motor rotor main shaft 1, and then by adjusting the height of the tiles until there is no axial movement, the axial margin is uniform, and the journal of the motor rotor main shaft 1 is roughly turned. Polish the end journal, CNC finish turning spline sleeve 2 to locate the shaft shoulder...

Abstract

The invention discloses a connecting method of a pure electrical vehicle driving system, comprising the following steps of: A, processing a motor rotor main shaft (1); B, processing a spline sleeve (2); C, processing a connecting flange (3); and D, connecting and assembling. The method has the advantages of accuracy and convenience in positioning, high processing precision, and little error; the matching quality of connecting pieces is ensured; and the whole system is stable in running.

Description

technical field [0001] The invention relates to a connection method of a rotating shaft, in particular to a connection method of a drive system of a pure electric vehicle. Background technique [0002] After the motor of pure electric vehicle is assembled, such as figure 1 As shown, the motor is connected through flange, spline and gearbox, which integrates the gearbox and the motor into an organic whole, and its connection method will directly affect the user's installation accuracy. At present, in the mechanical inspection of the whole machine, it is found that the runout value of the front cover installation connection flange is too large and the distribution center is not stable. Through analysis, the large spline processing error and the inaccurate installation and positioning reference are the causes of the flange runout. main reason. Contents of the invention [0003] The purpose of the present invention is to provide a connection method for a pure electric vehicl...
