Problems solved by technology

[0003] The existing braking test devices for commercial vehicles generally develop a set of proprietary test devices for one test, that is, each test corresponds to a set of dedicated test devices. The function of the test device is very single. For this type of braking test, the existing test device cannot be completed, and the versatility is poor

Embodiment Construction

[0044] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0045] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the figure). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0046] In addition, in the present invention, descriptions such as "first", "second" and so on are used for description purposes only, and should not be understood as indicating or implying their relative importance or implicitly indicating the quantity of indicated technical features. Thus, the features defined as...

Abstract

The invention relates to the technical field of automobile test devices, and discloses a multifunctional brake test device and test method for commercial vehicles. The test device includes: an air tank; The reversing valve, the air dryer and the first on-off valve; the first on-off valve communicates with the gas tank; the second pipeline includes the connected second reversing valve, damper and trailer control line connector; the second reversing The valve is connected with the gas tank; the third pipeline includes the connected second on-off valve, the electric pressure regulating valve and the third on-off valve; the second on-off valve is connected with the gas tank; the fourth pipeline includes the connected tractor control The pipeline joint and the fourth on-off valve; the fifth pipeline includes the connected fifth on-off valve and the trailer energy supply pipeline joint; the fifth on-off valve is connected to the gas tank; the second reversing valve is connected to the sixth A cut-off valve; a seventh cut-off valve is connected between the first reversing valve and the joint of the trailer energy supply pipeline. The invention has the advantages that the test device has multiple functions, wide application range and low cost.

Description

technical field [0001] The invention relates to the technical field of automobile test devices, in particular to a multifunctional brake test device and a test method for commercial vehicles. Background technique [0002] The braking system is an important link to ensure driving safety. Many traffic accidents are related to the braking system. Vehicles such as commercial vehicles and trailers are widely used in transportation, and in general, they are heavy and bulky. If a traffic accident occurs, both the vehicle and the personnel will be seriously injured. . Therefore, before leaving the factory, such commercial vehicles and trailers have a strict inspection and testing process for their braking systems, requiring vehicles to meet national standards before they can be used in the market. For example: car brake system response time test, measuring the time required for braking; car adhesion coefficient utilization rate test, looking for the critical point between car lock...
