Abstract

The invention relates to a synchronous power device applied to an electric bicycle performance test platform. The device comprises a base, a driving roller and a driven roller. The driving roller andthe driven roller are arranged inside the base with an adjustable interval. A positioning gear is arranged on the base. A drive motor is arranged on one side of the driving roller, and a driving gearis arranged on the other side. A driven gear is arranged on one side of the driven roller. A number of tensioning wheels are arranged on both sides of the driving gear. The driving gear, the tensioning wheels, the positioning gear and the driven gear are in transmission connection through a rack synchronous belt. The synchronous power device can reduce the horizontal static friction force appliedto a wheel when front and rear rollers rotate under the precondition of ensuring the power of front and rear rollers. The total length of a transmission belt is shortened. The problem of fatigue stretch caused by multiple uses of the device is solved.

Description

technical field [0001] The invention belongs to the technical field of testing electric bicycles, and in particular relates to an electric bicycle performance testing platform, in particular to a synchronous power device for the electric bicycle performance testing platform. Background technique [0002] The electric bicycle performance test platform is a kind of equipment for testing electric bicycles. During the test, the electric bicycle is placed on the rollers of the test platform to simulate the road riding state to test its various performances in the riding state. At present, most electric bicycles are detected by the motor front-mounted method, and the bicycle is driven by a motor located at the front axle of the bicycle. If the rider needs to pedal, the power transmitted to the rear axle through the pedals, crank and center axle can also produce auxiliary propulsion for the movement of the electric bicycle. The two powers are coupled through the ground, so that th...
