Problems solved by technology

[0003] Because electric bicycle / portable electric motorcycle performance testing platform itself has many and bigger frictional forces, and there is frictional resistance between the electric vehicle wheel and the rolling wheel of testing platform (the frictional resistance between the wheel and the rolling wheel of testing platform increases with Tire pattern, tire width, and tire inflation are different), so when using the test platform to test electric vehicles, electric vehicles need to overcome the above uncertain resistance to run, which will cause inaccurate test results.
[0004] At the same time, in the prior art, the test platform cannot quantitatively simulate the state of the car body subject to different resistances (the frictional force of the test platform itself and the friction resistance between the wheels and the rollers of the test platform are uncertain, so the test platform cannot load quantitative resistance on the car body), making it impossible to quantitatively test the performance of bicycles / mopeds under different resistances

Abstract

The invention discloses an electric bicycle performance test platform comprising a rear wheel driving device and a vehicle seat compressing device. The wheel driving device comprises a first rear axle roller and a second rear axle roller. The first rear axle roller and the second rear axle roller are fixed in a mutually parallel way through bearing pedestals. The first rear axle roller is connected with a first motor. The second rear axle roller is connected with a second motor. The rear wheel of a tested vehicle body is arranged in the two rear axle rollers of the rear wheel driving device. The vehicle seat compressing device is used for loading compressing force for the tested vehicle body so as to simulate vehicle-mounted weight. The second motor and the second rear axle roller load positive torque to the rear wheel of the vehicle body to apply push force and the vehicle wheel is enabled to be in the critical operation state so as to compensate frictional force of the test platform and frictional resistance between the vehicle wheel of the electric vehicle and the rollers of the test platform. The first motor and the first rear axle roller load opposite torque to the rear wheel to apply resistance so as to quantitatively simulate the resistance in driving of the electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of testing electric bicycles, and in particular relates to a performance testing platform for electric bicycles. Background technique [0002] The bicycle / moped electric motorcycle performance test platform is a kind of equipment for testing bicycle / moped electric motorcycle. During the test, the bicycle / moped electric motorcycle is placed on the rollers of the test platform to simulate the road riding state to test the electric vehicle Various performances in the riding state. [0003] Because electric bicycle / portable electric motorcycle performance testing platform itself has many and bigger frictional forces, and there is frictional resistance between the electric vehicle wheel and the rolling wheel of testing platform (the frictional resistance between the wheel and the rolling wheel of testing platform increases with The tire pattern, tire width, and tire inflation are different), so when using the te...
