Embodiment Construction
[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0018] Such as figure 1 As shown, an electric vehicle transmission includes a shifter, a synchronizer, and a transmission mechanism.
[0019] The transmission mechanism includes an output shaft 18 and an intermediate shaft 21. An input gear 26 and an output gear 20 are sleeved on the output shaft 18 respectively. One end of the intermediate shaft 21 is sleeved with a transmission gear 22 meshing with the input gear 26. The other end of the intermediate shaft 21 is...

The invention provides an electromobile transmission. The electromobile transmission comprises a shifter, a synchronizer and a transmission mechanism; the transmission mechanism comprises an output shaft and an intermediate shaft; a first synchronization tooth taper sleeve and a second synchronization tooth taper sleeve are each sleeved with a gear, a fixed tooth base is sleeved with a synchronization tooth ring, the synchronization tooth ring is sleeved with a sliding sleeve, and an internal tooth structure is arranged on the inner wall of the sliding sleeve; and the shifter comprises a body, a fork shaft is horizontally arranged in the body, permanent magnet rings are arranged at the two ends of the fork shaft, and electromagnetic coils are arranged at the two ends of the body and cooperate with the permanent magnet rings to drive the fork shaft to move in the axial direction. According to the electromobile transmission, the number of control links is small, operation is easy and convenient, the gear shifting reliability is high, full play is given to the dynamic performance of a motor effectively through gear shifting and speed regulation, the motor efficiency is higher, the energy saving effect is achieved, and the transmission efficiency is greatly improved.
Description
technical field [0001] The invention relates to a gear shifting device for an electric vehicle, in particular to a transmission for an electric vehicle. Background technique [0002] The development of electric vehicles is the hotspot of automobile development now. For the gearboxes of electric vehicles, the conventional practice of various manufacturers is to copy the manual gearboxes on fuel vehicles to electric vehicles, but the manual gearboxes are controlled by the clutch pedal and the shift lever. The cooperation of the fork makes the fork slide on the guide rod, and the fork pushes the synchronizer and the sleeve to change the meshing object to realize gear shifting. Not only are there many control links, the operation is cumbersome, and the gear shifting reliability is poor. [0003] There are also electric vehicles that change the speed of the motor by adjusting the voltage and current input to the motor, but when the motor is adjusted to run at a low speed, the out...
