The excessive problem of ligand one direction length improves the layout of motor and retarder.
The transmission reversing mechanism of the electric vehicle includes: transmission reversing mechanism, motor and retarder, and the motor is logical
It crosses transmission reversing mechanism to be connected with the retarder, sets the motor and retarder side by side by the transmission reversing mechanism
It sets.
The transmission reversing mechanism is pitch wheel A and gear B, enables the power output shaft of the motor for transmission
The input shaft of reversing mechanism, the input shaft of retarder are the output shaft for being driven reversing mechanism;The gear A 2 and transmission reversing machine
The input shaft of structure is coaxially affixed, and the gear B and the output shaft of transmission reversing mechanism are coaxially affixed.
The transmission reversing mechanism setting is provided on a side end face of the transmission reversing box in transmission reversing box
Two groups of screw thread hole locations are respectively used to fixed servo motor and retarder, and are arranged on the side end face of the transmission reversing box
There is the through-hole of the input shaft and output shaft for installing transmission reversing mechanism, passes through the threaded hole on the transmission reversing box end face
Position and the position of through-hole guarantee the meshing relation of the gear A being located in the transmission reversing box and gear B.
The input shaft and output shaft for being driven reversing mechanism pass through outside framework oil seal respectively and are mounted on the upper of the transmission reversing box
In corresponding through-hole.
The utility model has the advantages that
(1) present invention realizes power transmission commutation by one group of gear set, allows servo motor and retarder side by side
The space layout problem that parallel assembly installation, so assembly improve servo motor and retarder assembly is rationally utilized from new
Assembly space improves space utilization rate, prevents assembly single direction oversized and causes distributed driving integral arrangement tired
Hardly possible can not even arrange.
(2) guarantee that gear is meshed relationship, saves by the fixation position of input terminal and output end on transmission reversing box
The use of bearing.After bearing saves, the weight and volume of reversing mechanism are greatly reduced, while making reversing mechanism
Whole assembly become simply to be easy;The thickness of shell can greatly reduce, without the installation space for designing bearing;Secondly, shell
The design of body also greatly simplifies, and only uses single side aperture, and the sealing performance of shell oil liquid sealing also greatly improves.Eliminate bearing
Also imply that the related accessories for eliminating bearing installation simultaneously, such as the circlip of axially position, sleeve, lubricating cup are sealed and used
Asbestos, outside framework oil seal etc..Cost on the one hand is significantly reduced while saving a large amount of parts, while also mitigating transmission case
Weight and volume, the reduction in volume improve whole assembly Layout Problem again, improve space utilization rate, solve distributed drive
The problem of motor-car difficult arrangement.In addition to this more importantly improving the reliability of transmission case.Because of the part used
Fewer, system is simpler, and part failure in need of consideration is also fewer, and the stability of system greatly improves.
