Technical Field
The utility model belongs to the technical field of the car, specific new forms of energy car drive shaft fixed bolster that says so.
Background
At present, new energy automobiles are mostly in an electric driving assembly form of 'a motor + a speed reducer', and the speed reducer is arranged to be deviated to the left side or the right side of an automobile body. The distance from the driving shaft connected with the speed reducer to the left wheel and the right wheel is one side long while the other side is short, and if the included angles of the shaft levers of the driving shafts on the two sides and the rotation axes of the wheels are different, the risk of acceleration deviation exists. To avoid this risk, most vehicles add a section of intermediate shaft on the long side, making the included angle between the left and right drive shafts and the wheel rotation axis the same. If the length of the intermediate shaft is long, the intermediate support needs to be added, which is why a drive shaft fixing bracket is needed. The driving shaft fixing support is generally fixed on the motor shell through a bolt, so that the motor shell is required to be provided with a threaded hole with a certain depth, but a channel for cooling liquid for motor heat dissipation, commonly called as a cooling water channel, is arranged on the motor shell, so that enough material thickness is required to be arranged around the threaded hole to ensure that the cooling water channel is not damaged, and the weight of the shell is increased invisibly.
