Abstract

The invention discloses a continuously variable transmission device used for an electric car and the electric car. The continuously variable transmission device comprises a driving wheel mechanism, adriven wheel mechanism, a flexible transmission mechanism and a pushing mechanism; and the driving wheel mechanism comprises a movable driving wheel disc and a fixed driving wheel disc, and the pushing mechanism is connected to the movable driving wheel disc and can output continuously-changed power to enable the movable driving wheel disc to be capable of moving to the position where a preset distance is reserved between the movable driving wheel disc and the fixed driving wheel disc. The pushing mechanism enables the movable driving wheel disc to be capable of accurately moving to the specific position, the working pitch circle of the flexible transmission mechanism is accordingly adjusted, and the aim of adjusting the gear ratio is achieved; and in the above process, the pushing mechanism is achieved through mechanical power, and stable adjustment of the gear ratio can be guaranteed.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a continuously variable transmission device for the electric vehicle and the electric vehicle. Background technique [0002] A continuously variable transmission is used to match with a hybrid vehicle or a pure electric vehicle. When climbing, the speed ratio is increased to make the climbing ability stronger, and will not cause a series of disadvantages such as low battery efficiency and shortened battery life due to excessive discharge current of the battery. When the power motor reverses, it can also realize the reverse function, and its acceleration and deceleration can be completed by the engine throttle or the power motor switch controlled by the foot pedal. It has the advantages of simple structure, convenient operation, low production cost, and easy promotion and popularization. . [0003] The clamping and speed ratio change of the metal pulley of the traditional contin...
