Axle weight and brake and vehicle speed combined test bench

Abstract

The invention discloses a small-sized integrated axle weight and brake and vehicle speed combined test bench. The axle weight and brake and vehicle speed combined test bench is composed of a test platform foundation frame, a left test bench framework, a right test bench framework and two testing systems, wherein the left test bench framework and the right test bench framework are connected with the test platform foundation frame through pressure sensors respectively mounted at four corners of the left test bench framework and four corners of the right test bench framework, the testing systems are mounted on the test bench frameworks, and each testing system is composed by a rotary drum, a lifting mechanism, a force measuring device, a rotation speed measuring device and a third rotary drum in a combination mode. According to the axle weight and brake and vehicle speed combined test bench, a brake test bench, a speedometer test bench and two sets of rotary drums of an axle load meter are combined to one group, a driving motor and a speed reducer are arranged in the rotary drums, due to the integrated design, the structure is simplified, the occupied space is reduced, cost is lowered, the space requirement for installation of other devices can be met, and a test vehicle is enabled to finish all testing tasks according to national standard requirements.

Description

technical field [0001] The invention relates to a device for detecting the safety performance of an automobile, more specifically, relates to a device for compound detection of axle load, braking and vehicle speed. Background technique [0002] With the continuous updating of military equipment and the continuous improvement of the degree of mechanization, the number of military vehicles and equipment is gradually increasing. One of the important methods to ensure the good condition of vehicles in peacetime and wartime is to realize the regular inspection of vehicles. If the safety performance of the vehicle is not tested, the hidden dangers of the vehicle failure are checked and eliminated in time, traffic accidents may occur. Troop vehicles have special characteristics. In addition to completing daily life and logistical support, they also undertake the tasks of transport vehicles and weapon platforms in wartime. This puts forward higher requirements for the safety perform...
