Abstract

The invention discloses a continuously variable transmission, a vehicle and a brake control method.The continuously variable transmission comprises a driving transmission surface and a driven transmission surface, the driving transmission surface comprises a first driving transmission area and a second driving transmission area, and the surface roughness of the first driving transmission area is different from that of the second driving transmission area; the driven transmission face comprises a first driven transmission area and a second driven transmission area, and the surface roughness of the first driven transmission area is different from that of the second driven transmission area. When the vehicle is in a downhill working condition, along with downhill of the vehicle, the driven wheel reversely drives the driving wheel, so that the gap between the driving wheel movable disc and the driving wheel fixed disc at the driving wheel is smaller than the width of the transmission belt, the transmission belt is extruded to be located in the first driving transmission area, and large friction force exists between the driving wheel and the transmission belt; rotation of the driven wheel is limited, operation of the gear box connected with the driven wheel is limited, the gear box is connected with the wheel through a ball cage and the like, and therefore the downhill braking function is achieved.

Description

technical field [0001] The invention relates to the technical field of downhill braking, in particular to a continuously variable transmission, a vehicle and a braking control method. Background technique [0002] Continuously variable transmission, referred to as CVT, includes a driving wheel, a driven wheel and a transmission belt. The driving wheel is connected to the crankshaft of the engine. When the engine is working, the crankshaft rotates to drive the driving wheel to rotate; The indirect connection is formed through the gear box and the ball cage, etc. [0003] Generally speaking, the driving wheel includes a coaxial and oppositely arranged driving disk and a driving fixed disk. The driving disk can move closer to and away from the driving fixed disk to squeeze both sides of the transmission belt, so that the transmission belt moves radially along the driving wheel. Then realize the transmission diameter adjustment of the driving wheel; the driven wheel includes a ...
