The invention discloses a new energy automobile transmission device which comprises a motor, a clutch and a gearbox. The clutch comprises a flywheel, an output shaft and a driven mechanism. The motoris fixedly connected with the flywheel through a transmission shaft, a cover body is fixedly connected to the flywheel, a shaft sleeve is installed at the top of the cover body, and a diaphragm springis fixedly connected into the cover body. A pressing disk and a release bearing are arranged on the two sides of the diaphragm spring respectively. The pressing disk is fixedly connected with the outer ring of the diaphragm spring, and the release bearing is in contact connection with the inner ring of the diaphragm spring. The release bearing is matched with the shaft sleeve. The driven mechanism is located between the flywheel and the pressing disk and further comprises a driven disk and a friction plate fixed to the driven disk, and a buffering part is arranged on the driven disk. According to the new energy automobile transmission device provided by the invention, when the friction plate makes contact with the flywheel, part of acting force can be counteracted through the buffering part on the driven disk, so that the buffering effect on impact loads is achieved, the driven mechanism is protected against being damaged, and the service life is prolonged.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a new energy automobile transmission device. Background technique [0002] With the increasing consumption of petroleum energy in the world and the deteriorating environment, environmentally friendly electric vehicles driven by electricity are getting more and more attention, and their development is also getting faster and faster. [0003] Most electric vehicles directly drive the wheels to rotate through the motor, but they have the disadvantages of slow start, small power output, and easy damage to the motor. Therefore, clutches and transmissions are needed in electric vehicles. In the prior art, the clutch is generally arranged in the flywheel housing between the motor and the gearbox, and the clutch assembly is fixed on the rear plane of the flywheel with screws. The output shaft of the clutch is the input shaft of the gearbox. The driver can step on or loosen the clutc...
