Problems solved by technology

But at present in China, even professional motor vehicle inspection stations cannot meet the above conditions, such as braking tests. At present, there are all reaction-type braking tables in China, which can only detect the maximum braking force when the wheels are locked, and cannot reflect The whole process of braking and the speed of the braking of each wheel cannot detect the braking situation of the car equipped with the anti-lock braking system ABS; another example is the sliding test that comprehensively reflects the resistance of the car transmission system, which can only be completed with a chassis dynamometer. This kind of equipment is bulky and requires a lot of investment, which is unbearable for enterprises

Embodiment Construction

[0018] The invention is composed of a braking platform, a lifting platform, a connecting bridge, an approach bridge, a detection disc, a computer and a console. Among them, the brake platform and the lifting platform are the main mechanical structures, which are connected in series by the connecting bridge and allow the wheels to pass through. The approach bridge is just a slope for the car to go up and down the lifting platform, as shown in Figure 1 and Figure 2.

[0019] 1. Braking table. The main bench for braking and sliding tests can also load and position the wheels of the non-detection axis when detecting the steering. It consists of the base 1, the roller group 2, the third roller 3, the motor and pulley 4, the clutch 5, Riser 6, rear axle seat 7 etc. are formed.

[0020] 1.1. Base 1. The four-shaped base welded by channel steel is the basis for carrying and connecting all parts on the brake platform.

[0021] 1.2. Roller group 2. It consists of four independent ro...

Abstract

This invention discloses a car chassis test bed which can check car performances such as braking, sliding, steering, positioning for front and rear wheel. The equipment is integrally located above the ground. It comprises brake platform, lifting platform, left and right checking pan, linking bridge, approach bridge, computer and operating console. The brake platform belongs to the minute wheel, roll, and inertia type and is composed of four rolls and is driven by a induction alternating current motor through a belt pulley and a clutch. And there is a guard against the wheel dropping out of the roll. There is a rail on the lifting platform to be used for the longitudinal parallel move of the checking pan. The checking pan is composed of longitudinal pulley, transverse pulley and dip meter.

Description

Technical field [0001] The invention relates to a detection device for detecting the performance of an automobile chassis, in particular to a test bench for a small automobile chassis. Background technique [0002] With the rapid increase of domestic car ownership, car maintenance companies and business volume also increase proportionally, among which, the maintenance work of brake system and steering system is the largest workload. Since it is not allowed to test the car on the road, and in order to improve work efficiency, it has become the basic condition and requirement for small car maintenance companies to complete the test and detection of braking, sliding, steering, front and rear wheel alignment, etc. on the job site. But at present in China, even professional motor vehicle inspection stations cannot meet the above conditions, such as braking tests. At present, domestically, there are all reaction-type braking tables, which can only detect the maximum braking force ...
