Problems solved by technology
[0002] ATV / UTV is an automatic centrifugal clutch. When the engine is idling, the clutch will not engage (that is, the neutral state). If the clutch is not engaged when going downhill, the car will always coast in neutral, and the speed will increase. The faster the speed, there are potential safety hazards. The traditional braking device relies on the friction generated by the bottom of the belt to rub against the one-way bearing seat to achieve the braking effect, but the belt is not easy to clamp, and the braking effect is poor and the life of the belt is short.

technical field [0001] The invention relates to the technical field of transmissions, in particular to a continuously variable transmission with a downhill braking function. Background technique [0002] ATV / UTV is an automatic centrifugal clutch. When the engine is idling, the clutch will not engage (that is, the neutral state). If the clutch is not engaged when going downhill, the car will always coast in neutral, and the speed will increase. The faster the speed, there are potential safety hazards. The traditional braking device relies on the friction generated by the bottom of the belt to rub against the one-way bearing seat to achieve the braking effect, but the belt is not easy to clamp, and the braking effect is poor and the belt life is short. Contents of the invention [0003] The invention provides a stepless transmission with downhill braking function. The braking device is installed on the driving fixed shaft. The action effect is effective, the braking effect...
