New energy automobile driving integrated system motor structure

Abstract

The invention provides a new energy automobile driving integrated system motor structure applied to the technical field of new energy automobiles. The new energy automobile driving integrated system motor structure comprises a motor rotating shaft (1), a bearing pressing plate (2), a bearing (3) and a motor rear end cover (4). A bearing chamber is arranged on one side of the motor rear end cover (4). The motor rotating shaft (1) comprises a bearing assembling part (5) and a bearing end face (6), a pressing plate installing part (7) is arranged between the bearing assembling part (5) and the bearing end face (6), a bearing step face (8) is arranged at the pressing plate installing part (7), a middle through hole (9) is formed in the bearing pressing plate (2), and a pressing plate step face(10) is arranged at the middle through hole. The new energy automobile driving integrated system motor structure is simple in structure, the bearing pressing plate is convenient to install in the newenergy automobile drive integrated system motor, the installation process is simplified, and the installation efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and more specifically relates to a new energy vehicle drive integration system motor structure. Background technique [0002] With the development of new energy vehicles, the independent main drive motor, reducer and motor controller can no longer meet the requirements of the vehicle manufacturer. Now the vehicle manufacturer needs to use the motor, motor controller and reducer The scheme of machine combined into drive system integration system. [0003] At present, in a traditional driving motor, the bearing outer ring at the front end of the rotor needs to be axially fixed in the bearing chamber of the motor front end cover, and the bearing outer ring is usually fixed axially by a bearing pressure plate. There are multiple threaded holes on the bearing pressure plate, and multiple threaded through holes corresponding to the position of the bearing pressure plate on the motor end co...

AI Technical Summary

Problems solved by technology

However, since the motor of the drive integrated system cancels the front end cover, the bearing pressure plate must be installed on the side of the rear end cover

In the assembly sequence, the motor water jacket and rear end cover are installed before the bearing pressure plate, which causes the thread on the bearing pressure plate to be fixed with the threaded hole of the rear end cover, because the bearing pressure plate is inside the water jacket and rear end cover, and the bearing pressure plate The threaded hole of the bearing is blocked by the rear end cover, and the bearing pressure plate cannot be adjusted

For such a structure, the method in the prior art is to use a special long screw to pass through the threaded hole of the rear end cover before the bearing pressure plate is installed. This way makes the installation process of the bearing pressure plate complicated and the installation efficiency low
