A heavy-duty reproducible brake detection test device for heavy-duty multi-axle vehicles

Abstract

The invention relates to a vehicle detection equipment detection device in the field of vehicle industry, and especially relates to a heavy-load reappearance-type braking detection test device for a heavy-type multi-axle truck. The device comprises four lifting mechanisms in the same structure, and the four lifting mechanisms are disposed on four horizontal foundation planes with the same depths. The first lifting mechanism and the second lifting mechanism are placed in front of a roller braking test bench V side by side in an aligned manner, and the third and fourth lifting mechanisms are placed at back of the roller braking test bench V side by side in an aligned manner. According to the invention, the front and back of a conventional roller braking test bench are provided with the lifting mechanisms, thereby meeting the detection requirements. An on-site detection field is used reasonably, thereby reducing the reconstruction process. The device is economical and reasonable, and is universal. Moreover, the lifting mechanisms can achieve the braking detection of the multi-axle truck, and a wheel and axle which are not detected are departed from the ground at the same time, thereby meeting the requirements of heavy load reappearance, and achieving the measurement of the loading braking performance of a detected axle.

Description

technical field [0001] The invention relates to a detection device for automobile detection equipment in the field of the automobile industry, in particular to a heavy-duty multi-axle vehicle heavy-load reproducible brake detection test device. Background technique [0002] With the rapid development of national defense modernization and national economy, some special vehicles with high power and large carrying capacity have been widely used. Due to the limitation of road surface conditions and traffic regulations, simply relying on increasing the bearing capacity of a single axle and reducing the quality of the whole vehicle can no longer meet the requirements. The only way to meet the requirements of the national standard is to increase the number of axles. Therefore, the safety performance of multi-axle vehicles has been paid more and more attention. [0003] According to the latest revision of GB21861 "Motor Vehicle Safety Technical Inspection Items and Methods", the st...
