Embodiment Construction

[0018] In conjunction with the accompanying drawings, the structure and working process of the present invention will be described in detail below.

[0019] Such as figure 1 As shown, the power integration mechanism includes a drive motor and a transmission. The drive motor 7 is installed in the motor water jacket 5. The rear end of the motor water jacket 5 is installed with the motor rear end cover 6. The front end of the motor water jacket 5 is integrally cast with a drive motor. Share the housing 1 with the transmission. The motor power output shaft 3 of the driving motor passes through the bearing hole on the common housing 1 of the driving motor and the transmission toward the front end, extends into the common housing 1 of the driving motor and the transmission, and is supported by the gear bearing 2 installed in the bearing hole, The transmission gear 4 of the speed changer is assembled at the output end of the motor power output shaft 3 .

[0020] The internal design...

Abstract

The invention provides a power integrated structure of a driving motor and a transmission of an electric automobile, which comprises the driving motor and the transmission; the driving motor is installed in a motor water jacket; the rear end of the motor water jacket is provided with a rear end cover of the motor; the front end of the motor water jacket is integrally cast into a shared shell for the driving motor and the transmission; a motor power output shaft of the driving motor goes forward to pass through a bearing hole of the shared shell of the driving motor and the transmission, is stretched into the shared shell of the driving motor and the transmission, and is supported by a gear bearing installed in the bearing hole; and a transmission gear of the transmission is assembled at the output end of the motor power output shaft. Due to the adoption of the invention, the front end cover of the motor and the shell of the transmission are designed as a whole, thus the requirement of installation in a limited space can be met and the use reliability of the power integrated structure is guaranteed.

Description

technical field [0001] The invention belongs to the field of motors and transmissions of automobiles, and in particular relates to the dynamic structure of motors and transmissions used in new energy electric vehicles, including the use in plug-in automobiles. Background technique [0002] The driving motor and the transmission constitute the powertrain mechanism of the new energy electric vehicle. The powertrain mechanism is the key equipment on the electric vehicle. At present, in order to meet the installation requirements of the motor on the vehicle, most motors and transmissions are in the form of two independent parts. Assembled on the vehicle body, the output shaft of the motor is an external spline structure, and the transmission gear is an internal spline structure, forming a matching assembly method in which the internal and external splines are inserted. This will increase the mechanical noise and reduce the service life, and the mechanical strength is also guaran...
