Abstract
Description
Technical Field
[0001] The utility model relates to a clamping type metal ring based on a new energy vehicle transmission, belonging to the technical field of new energy vehicles. Background Art
[0002] New energy vehicles refer to vehicles that use electric motors as their main power source, including pure electric vehicles, plug-in hybrid vehicles, and fuel cell vehicles. Their transmissions are usually driven directly by electric motors, so they are different from the mechanical transmissions used in traditional internal combustion engine vehicles. The transmission of new energy vehicles refers more to the electronic control system of electric vehicles, which is used to adjust the speed and torque of the motor to adapt to different driving conditions and driving requirements, and achieve more efficient power transmission and energy utilization.
[0003] In the transmission, the metal ring plays an important role as a synchronizer. When gear shifting is required, the metal ring makes the shift gear and other gears synchronize at the same speed through the friction with the synchronizer gear, thereby achieving a smooth gear shifting process. However, due to the frequent friction between the metal ring and the synchronizer gear, it is necessary to have high wear resistance. The existing transmission metal ring may have insufficient wear resistance. Under long-term wear, wear and dents will appear on its surface, which will affect the friction effect between the synchronizer and the gear, making the gear shifting process no longer smooth, which will cause jerking, abnormal noise or difficulty in shifting, affecting driving comfort and safety. If the gear shifting is not smooth, the driver may not be able to quickly control the speed and power output of the vehicle in an emergency, which increases the safety hazard of driving and may cause traffic accidents.
[0004] To this end, a snap-on metal ring based on a new energy vehicle transmission is proposed. Utility Model Content
