Embodiment Construction
[0008] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0009] The booster low-slip automobile ABS / ASR comprehensive test system is composed of front and rear axle test benches with the same structure; the front and rear axle test benches are respectively composed of two left and right wheel test benches with the same function and symmetrical structure. The four wheel test stands can be controlled independently, such as figure 1 , 2 , 3 shown; taking the left front wheel test rig (the test rigs of the other three wheels have the same composition) as an example, it consists of a flywheel (1), a brake drive transmission device (2), a slip torque control device (3) , shaft coupling (4), torque speed sensor (5), third drum (6), front and rear drum transmission device (7), frame (8), rear drum (9), drum brake Lifting platform and weighing platform (10), front drum (11), wheelbase adjustment mechanism of the same wheel drum (...

The invention provides a boosting type low-sliding-ware automobile anti-lock braking system / automatic slip regulation (ABS / ASR) comprehensive test system. The boosting type low-sliding-ware automobile ABS / ASR comprehensive test system consists of a front shaft test stand and a rear shaft test stand which have the same structure, wherein the front shaft test stand and the rear shaft test stand consist of two left wheel test stands and two right wheel test stands respectively; the two left wheel test stands and the two right wheel test stands have the same function and are structurally symmetrical with one another; four wheel test stands can perform independent control and can increase axle distance between two revolving drums of the same wheel as much as possible through same wheel revolving drum axle distance adjusting threaded rods (12), so that threshold friction between each wheel and each revolving drum can be increased; and the maximum value s of the axle distance between the two revolving drums of the same wheel can be calculated through a geometrical relationship, according to the known quantity of wheel radius Rw, revolving drum radius Rd and ground clearance h of an automobile, and under the condition of setting safety clearance d between the bottom of the automobile and the test stands.
Description
technical field [0001] The invention relates to the comprehensive test technology of automobile ABS / ASR control test research and performance test. The automobile ABS (Anti-lock Braking System) device refers to the automobile anti-lock brake device, the automobile ASR (Automatic Slip Regulation) device refers to the automobile drive anti-skid device, and the automobile ABS / ASR device refers to the automobile with the brake anti-lock brake at the same time. Function and device for actuating the anti-skid function. Background technique [0002] At present, the domestic and foreign existing manufacturers of automobile dynamic control test benches are relatively well-known such as Link Company and Greening Company of the United States, Schenck Company of Germany, etc., and Beijing Institute of Technology in China also has related research and patent applications. The current automobile ABS test bench mainly tests the control performance of ABS by measuring the braking force and...
