Abstract

The invention discloses a non-impact-shaft transmission system, an electric motorcycle power system and an electric motorcycle. The power system comprises a rear transmission box used for driving a rear hub of a vehicle to rotate. A flange plate is included, and a first connecting structure which is fixedly connected with the rear hub based on the hub bolt is arranged on the flange plate; the rear transmission box comprises a rear box body and an output disc gear; the flange plate is fixedly connected to the output plate gear; or the flange plate is fixedly connected with the output plate gear through a third component. The electric motorcycle power system comprises the impact-free shaft transmission system and a driving motor. The electric motorcycle comprises the electric motorcycle power system. The transmission system has the beneficial effects that power transmission of the transmission system is impact-free, the structure is simple, and the service life is long; and the power system is compact in layout, and the electric motorcycle is impact-free in start and stop and low in noise and meets the low-carbon and environment-friendly requirements.

Description

technical field [0001] The invention relates to a motorcycle power system, in particular to a non-impact shaft transmission system, an electric motorcycle power system and an electric motorcycle. Background technique [0002] An electric motorcycle is a motorcycle that uses batteries as its energy source and converts electrical energy into mechanical energy by a motor. Existing electric motorcycle mainly has three kinds of structural forms, and the one, hub motor structure, and motor is located at the inside of hub. The other is the side-mounted motor structure, and the motor reducer is arranged outside the hub; the other is to install the motor on the frame, and transmit the power to the rear hub through a chain or a transmission shaft. Due to space constraints, the motor power of the hub motor structure is small, and the heat dissipation effect is poor, and the failure rate is high; the side-mounted motor structure is installed on the rear wheel due to the motor and decel...
