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 performance test and matching test bench of a Baja racing transmission system. The test bench comprises a Bach racing engine, a buncher, a main reducing gear, and a magneticpowder brake that are connected successively by a coupler and a torque speed sensor. The Bach racing engine is connected with a throttle position adjuster and a throttle valve position adjuster respectively; the magnetic powder brake is connected to a data switch controller; the torque speed sensor is connected with a signal conditioning module and a data acquisition instrument successively; the throttle position adjuster, the throttle valve position adjuster, and the data switch controller are connected with a fast control prototype; and the fast control prototype is connected to a computer and a display device. The test bench is capable of simulating the real-time condition of the Baja racing and the simulation performance test of the Baja racing engine can be carried out; the test precision is high; the transmission efficiency and shifting rules of the buncher can be analyzed; the performance adjustment of the Baja racing engine is carried out; and an optimal transmission ratio of the main reducing gear is 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...
