Problems solved by technology

The existing Baja racing car transmission system performance test and matching test bench is mainly modified on the mechanical ordinary transmission bench test device or directly carried out the continuously variable transmission bench test on the real car. The functions realized by the test are too single and not targeted. Strong, it is impossible to adjust the engine of the Baja racing car and select the transmission ratio of the main reducer according to the competition requirements of the Baja racing car, and although the actual working conditions of the vehicle can be simulated, it cannot be adjusted in real time to make the vehicle in the best position.

Abstract

The invention discloses a Baja racing car transmission system performance test and matching test bench, which comprises a Baja racing car engine, a continuously variable transmission, a final reducer and a magnetic powder brake connected sequentially through a coupling and a torque speed sensor. The Baja racing car engine is respectively It is connected with the throttle position regulator and throttle position regulator, the magnetic powder brake is connected with the data switch controller, the torque speed sensor is connected with the signal conditioning module and the data acquisition instrument in turn, and the throttle position regulator, throttle position regulator, data switch control The controller and the data acquisition instrument are respectively connected to the rapid control prototype, and the rapid control prototype is connected to a computer and a display. The test bench can simulate the real-time working conditions of the Baja racing car and carry out the simulated performance test of the Baja racing car engine. The transmission ratio of the optimal main reducer can be selected.

Description

technical field [0001] The invention belongs to the field of automobile performance testing, and in particular relates to a performance testing and matching test bench for a Baja racing car transmission system. Background technique [0002] The performance test and matching test bench of Baja racing car's transmission system is of great significance for improving Baja racing car's power system, exploring CVT shifting rules, Baja racing car simulation performance test and selecting the transmission ratio of final drive. The existing Baja racing car transmission system performance test and matching test bench is mainly modified on the mechanical ordinary transmission bench test device or directly carried out the continuously variable transmission bench test on the real car. The functions realized by the test are too single and not targeted. Strong, it is impossible to adjust the engine of the Baja racing car and select the transmission ratio of the main reducer according to th...
