A light unmanned vehicle parameter test platform

Abstract

The invention discloses a light-duty unmanned vehicle parameter testing platform, and the platform comprises a first rolling wheel and a second rolling wheel, which are parallel to each other. A light-duty unmanned vehicle wheel contacts with the first and second rolling wheels at the same time, so as to simulate a driving road surface. The platform also comprises a torque sensor which is connected with the first rolling wheel and measures the torque transmitted by the first rolling wheel; a rotating speed sensor which is connected with the first rolling wheel and measures the rotating speed of the first rolling wheel; a magnetic powder brake which is used for providing wheel running resistance; and a transmission mechanism which is disposed between the magnetic powder brake and the first rolling wheel, and is used for power transmission. According to the invention, the first and second rolling wheels contact with the light-duty unmanned vehicle wheel, thereby improving the stability of a testing process. The platform provided by the invention can directly measure the power parameter of the wheels, which is of great significance to the evaluation and analysis of the whole vehicle in a driving process.

Description

technical field [0001] The invention relates to the technical field of light unmanned vehicle testing, in particular to a light unmanned vehicle parameter testing platform. Background technique [0002] The light unmanned vehicle drum test bench is a basic test equipment. The shaft end of the drum is installed on a hydraulic or electric dynamometer, which can generate a certain resistance torque to adjust the drum speed and control the speed of the driving wheel of the light unmanned vehicle. The light unmanned vehicle drum test bench simulates the inertia of the light unmanned vehicle and the road load of various working conditions in the road test, and completes the economy, power and reliability of the light unmanned vehicle indoors, which are related to the transmission of the light unmanned vehicle. special test. Compared with the traditional road test, the system has the characteristics of short test cycle, high speed, high precision, low cost, stable data, high comp...
