Abstract
The invention belongs to the technical field of electric vehicle power transmission, and discloses a transmission spindle with buffer. The transmission spindle solves the problem of an impact due to rigid combination during gear shift in the prior art. The transmission spindle with the buffer comprises a motor, wherein the motor is connected with a box body; a motor shaft, a spindle part and an output shaft are arranged in the box body; and respective self-transmitting gears are arranged on the motor shaft, the spindle part and the output shaft. The transmission spindle is characterized in that input teeth on the spindle part are provided with bumps; the bumps are arranged in grooves in a driving gear; one end of each damping spring pushes against the driving gear; the other end of each damping spring pushes against the bumps of the input teeth; and power of the motor generates the buffer through the mechanism, and then is transferred to the output shaft.

The object of the present invention is to provide a kind of simple in structurely in order to solve above-mentioned deficiency, volume is little, power is flexible in conjunction with output during gearshift, without impacting sense, make the driver more comfortable, and gear engagement is more durable.
For realizing purpose of the present invention, the first technological scheme of the present invention is: a kind of band buffering transmission main shaft, comprise motor, and motor is connected with casing, is provided with motor shaft, main shaft and output shaft in the casing, and above-mentioned axle is provided with the gear of separately transmission; It is characterized in that: the input tooth on the described main shaft is provided with groove, and damping spring is installed in the groove, and damping spring one end withstands on the input tooth, and the other end withstands on the projection of driving gear, and the power of motor passes to output shaft after producing buffering through said mechanism.
Described band buffering transmission main shaft, it is characterized in that: described input tooth is fixed on the main shaft, and driving gear then is enclosed within on the main shaft, and driving gear rotates at main shaft limitedly.
For realizing same purpose of the present invention, another kind of technological scheme of the present invention is: a kind of band buffering transmission main shaft, comprise motor, and motor is connected with casing, is provided with motor shaft, main shaft and output shaft in the casing, and above-mentioned axle is provided with the gear of separately transmission; It is characterized in that: the input tooth on the described main shaft is provided with projection, projection is arranged in the groove on the driving gear, damping spring one end withstands on driving gear, and the other end withstands on the projection of input tooth, and the power of motor passes to output shaft after producing buffering through said mechanism.
Described band buffering transmission main shaft, it is characterized in that: described input tooth is fixed on the main shaft, and driving gear then is enclosed within on the main shaft, and driving gear rotates at main shaft limitedly.
The present invention has following beneficial effect: the present invention is when using gearshift that impulsive torque is arranged, and damping spring is naturally compressed, produces shock absorbing effect, make gear flexible in conjunction with feeling without impacting, noise is little, reduces the damage of impacting machinery, also makes the driver feel more comfortable.
