Road simulator stand

Abstract

A road simulator stand is used for simulating vertical jumping of an automobile wheel. The road simulator stand comprises a plurality of supporting bases for supporting the automobile wheel, the supporting base comprises a base body, an actuator and a bearing part, fixing holes for fixing the supporting base are formed in the base body, and the actuator is located on the base body and is connected with the bearing part to provide power for the movement of the bearing part. The bearing part is located above the actuator and can vertically jump relative to the actuator, the bearing part is provided with containing space, and the bottom of the automobile wheel is located in the containing space. According to the road simulator stand, the actuator is arranged below the bearing part, and the actuator is utilized to provided power for the movement of the bearing part, so that vertical jump of the automobile wheel is simulated.

Description

technical field [0001] The invention relates to the field of automobiles, and in particular to a road simulation test bench for a complete automobile. Background technique [0002] With the rapid development of my country's automobile industry, automobile manufacturers need to gradually establish and improve their own design and development mechanism, and reliable test methods are an important part of it. [0003] In the process of automobile design and development, three types of tests are generally required, namely, actual road test, proving ground test and indoor bench test. Among them, the test methods of actual road test and proving ground test make the test cycle too long, Moreover, the experimental process is easily affected by factors such as weather, the test time cannot be accurately grasped, and the parameters of the experimental process cannot be precisely controlled. However, due to the advantages of good test repeatability and short test cycle, the indoor bench...

[0003] In the process of automobile design and development, three types of tests are generally required, namely, actual road test, proving ground test and indoor bench test. Among them, the test methods of actual road test and proving ground test make the test cycle too long, Moreover, the experimental process is easily affected by factors such as weather, the test time cannot be accurately grasped, and the parameters of the experimental process cannot be precisely controlled. However, due to the advantages of good test repeatability and short test cycle, the indoor bench test has become an important part of automobile design. Main test methods under development
