The invention provides an electric bicycle automatic speed change transmission mechanism with reverse gearing and sliding functions. The electric bicycle automatic speed change transmission mechanism consists of a speed changer, a driving disc, a one-way plate, a speed changer shaft, a gearbox, a telescopic rod, a spring, an electromagnetic valve, a sleeve pipe, a screw cover, a movable iron core and a static iron core, and is characterized in that the telescopic rod is arranged in an telescopic rod connecting chamber inner hole formed in a gearbox cavity, the spring is arranged at the radial outer part of the telescopic rod, a small shaft arranged above the telescopic rod is arranged in a through hole of the static iron core, the lower side of the telescopic rod is matched with a position limiting shaft, the static iron core is fixedly connected with the gearbox and the sleeve pipe, the sleeve pipe is arranged inside an inner hole of the electromagnetic valve and is tightly matched with the inner hole of the electromagnetic valve, an upper opening of the sleeve pipe is fixedly connected with the screw cover, the movable iron core is arranged in the inner diameter of the sleeve pipe, the electromagnetic valve controls the movable iron core to realize the suction and the separation, when the electromagnetic valve is in a normally open state, the movable iron core is sucked with the static iron core, and the electric motive power driving path is in a two-way driving mode; when the electromagnetic valve is in a normally closed state, the electric motive power driving path is in a one-way driving mode formed by driving disc pallets and one-way gear rings of a one-way plate.
Description
Technical field: [0001] The invention relates to the field of electric vehicles, in particular to an automatic transmission mechanism for electric vehicles with reverse gear and sliding functions. Background technique: [0002] The electronically controlled mechanical automatic transmission has the advantages of comfortable driving and reduced driver fatigue. The electric vehicle equipped with an automatic transmission can automatically change the speed and torque according to the road conditions, and the driver can concentrate on the road traffic without being confused by shifting gears. In a hurry, the AMT automatic transmission allows the driver to automatically change gears without cutting power. [0003] In order to solve the patent application No. 201110029082.9 electric tricycle, electric vehicle automatic variable speed motor transmission mechanism realizes the reverse gear function, the patent No. 201020523498.7 electric vehicle transmission sun gear two-way drive f...
