Embodiment Construction

[0048] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0049] Such as figure 1 As shown, the invention provides a flat-plate variable simulated road test device for simulating a car running on a road. The plate-type variable simulation road test device includes four road simulation mechanisms 110 and a driving mechanism.

[0050] The driving mechanism includes a dual-output-shaft variable-frequency speed-regulating motor 121 , an output shaft 122 , a bevel gear 123 and a transmission shaft 124 . The double-output-shaft variable-frequency speed-regulating motor 121 has the function of dual-shaft output, and is connected to two output shafts 122 respectively to transmit power to the two output shafts 122 . The output shaft 122 transmits power to the transmission shaft 124 through a pair of meshing bevel gears 123 , the transmissi...

Abstract

The invention discloses a flat board type changeable simulation road face testing device including four road face simulation mechanism in contact with four wheels. The road face simulation mechanism includes a drive chain wheel and a driven chain wheel; chain links connected in a head-to-tail manner so as to form a loop chain engaged with the drive chain wheel and the driven chain wheel; a T-shaped channel steel board connected with the chain links fixedly and provided with a through T-shaped groove; a T-shaped block fitting with the T-shaped groove so as to enable the T-shaped block to embed into the T-shaped groove in a dismountable manner; and bosses arranged at the top end of the T-shaped block and in contact with wheels so as to realize road face excitation to an automobile, wherein the chain links between the drive chain wheel and the driven chain wheel are kept horizontal. The device provided by the invention is simple in structure and reasonable in design. Different road faces can be simulated through changing the shapes and distribution of the bosses.

Description

technical field [0001] The invention relates to the technical field of road surface simulation test devices, in particular to a flat-plate variable simulated road surface test device. Background technique [0002] Although the automobile road test can reflect the performance of the automobile in an all-round way, it needs a specific site, and it is time-consuming and financially expensive. Therefore, in the 1960s, a road simulation test was developed for the whole vehicle indoors. With the rapid development of modern theory, control technology and computer technology, this method and equipment are becoming more and more perfect. Roughness, steering, braking, environmental impact, road simulation system for studying suspension characteristics, etc., various simulation test benches have been continuously developed and put into practical application. [0003] The traditional indoor vibration table test is realized by exciting the vehicle with a certain frequency of vibration t...
