Abstract

A speed change mechanism driven by an electric vehicle is provided with a gearbox body; a motor is arranged in the box body; an output shaft is driven by the gear shaft of the motor by a transmission mechanism; the output shaft drives the hub of the electric vehicle. The invention is characterized in that the transmission mechanism is that: the gear shaft of the motor drives a reduction gear set; the reduction gear set drives a switching shaft; one end of the switching shaft is provided with a friction switching gear; the other end of the switching shaft is provided with an overrunning switching gear; the overrunning switching shaft drives an overrunning clutch; the overrunning clutch is matched with the output shaft; a friction switching gear drives a multi-plate friction clutch; the multi-plate friction clutch is matched with the output shaft; one end of the friction clutch is provided with a switching device; the switching device is connected with a wire cable guy; the wire cable guy is connected with the handgrip of the electric vehicle. The technical scheme is safe and reliable to be used; the endurance capacity of the electric vehicle is strong; a battery and the motor are effectively protected; besides, the technical scheme has the advantages of stable shifting as well as convenient, flexible and reliable control.

Description

technical field [0001] The invention relates to a drive system of an electric vehicle, in particular to a drive transmission mechanism for an electric vehicle. Background technique [0002] Electric vehicles (mainly referring to electric bicycles) use batteries as energy sources and are driven by motors. They do not require manual pedaling, which saves effort. Compared with internal combustion engines such as motorcycles, they have lower noise, no exhaust gas, and less pollution, so they have developed rapidly. However, in-wheel motors are generally used in existing electric vehicles, that is, low-speed DC motors are directly driven. When climbing or starting, they can only rely on increasing the current (up to tens of amperes) to obtain high torque. The capacity will drop, and even cause damage to the energy storage element-battery, and if the overload is too large, the motor will be destroyed. Contents of the invention [0003] The purpose of the present invention is to...
