Abstract

The invention belongs to the technical field of gearboxes, and particularly relates to a gearbox for an automobile. The gearbox for the automobile comprises a connecting shaft, a first gear, a secondgear, a speed change shaft, a first one-way clutch, a third gear, a torsion sensing ring, a fourth gear and an elastic element; the first end of the connecting shaft is connected with an output shaftof a motor; the first gear and the second gear are arranged on the connecting shaft in a sleeved mode; a first thread section is arranged in the middle of the speed change shaft; the first one-way clutch is arranged on the speed change shaft in a sleeved mode; the third gear is arranged on the first one-way clutch in a sleeved mode and is meshed with the first gear; the torsion sensing ring is arranged on the speed change shaft in a sleeved mode, and is connected with the first threaded section in a threaded mode; the fourth gear is arranged on the torsion sensing ring in a sleeved mode and ismeshed with the second gear; and the first end of the elastic element is connected with a box body, and the second end of the elastic element is connected with the torsion sensing ring. The gearbox can sense the road resistance so as to achieve automatic gear shifting, so that the situation that the operation of the motor is unstable due to the fact that an improper gear which is adopted by the driver can be avoided.

Description

technical field [0001] The invention belongs to the technical field of gearboxes, in particular to gearboxes for automobiles. Background technique [0002] Electric vehicles refer to vehicles driven by motors, and their development prospects are widely optimistic. The gearbox is an important part of the car and is used to change the gear of the car. At present, the gearboxes of small and medium-sized electric vehicles generally adopt two shifting methods: one is electronic accelerator pedal shifting, that is, the driver can change the current by pressing the accelerator pedal to change the speed, but the shifting device is not easy to adjust the torque , It is difficult to adapt to the situation of mountains, hills or heavy loads; the other is manual mechanical transmission, that is, the driver changes the gear by turning the shift handle. [0003] However, the above-mentioned speed change methods are closely related to the driver's operating experience. For inexperienced ...
