Embodiment Construction

[0018] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific embodiments, structures, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0019] The road simulation test bench of the present invention is mainly used for the test of simulating the up and down beating of wheels. The road simulation test bench mainly includes several figure 1 The support base 100 is shown. If need utilize the present invention to carry out the uniaxial test of whole vehicle, only need two support bases 100 to support the front wheel of automobile, the rear wheel of automobile adopts other mode to support; If need utilize the present invention to carry out biaxial test of complete vehicle, then need four A supporting base 100 supports the front and rear wheels of the automobile respectively.

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...
