Abstract

The invention discloses a driving device for an automobile road test. The driving device comprises a base, upright posts, a moving frame, a steering wheel driving mechanism and a pedal driving mechanism, wherein the pedal driving mechanism is assembled on the base, the pedal driving mechanism is connected with a pedal mechanism of an original automobile, the upright posts are arranged on both sides of the base, the moving frame is penetrated on the upright posts, the steering wheel driving mechanism is arranged on the moving frame, and the steering wheel driving mechanism is connected with a steering wheel of the original automobile. The driving device has the advantages that the transmission efficiency is high, the service life is long, meanwhile, micro feed can be realized, and high precision control of the pedal stroke is realized. In the case of emergency circumstances such as sudden outage of the automatic driving device, an electromagnetic lock on a sliding table loses power, sothat a push rod deviates from the sliding table, an accelerator pedal automatically resets under the action of a tension spring and a compression spring, and a clutch pedal and a brake pedal are automatically pressed to achieve emergency braking.

Description

technical field [0001] The invention relates to a driving device, in particular to a driving device used for automobile road tests. Background technique [0002] At present, with the rapid development of the automobile industry, human beings have higher and higher requirements for the performance of automobiles, and a large number of experiments are needed to improve the design. However, many items in the automobile test are more suitable to be operated by the corresponding driving device due to their strong repeatability, long duration, high risk and harsh working environment. In the traditional automobile test process, the long-term concentrated work will make the driver physically and mentally exhausted, which seriously affects the safety of the driver. At the same time, the reliability of the experimental data collected in this environment is insufficient. Therefore, there is a need for a test driving device to replace a human driver in a car test to perform a series of...
