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

Abstract

The invention relates to the technical field of vehicle test devices, and discloses a multifunctional brake test device and test method for a commercial vehicle. The test device comprises a gas tank; a first pipeline which comprises a tractor energy supply pipeline connector, a first reversing valve, an air dryer and a first on-off valve which are communicated; wherein the first on-off valve is communicated with the gas tank; a second pipeline which comprises a second reversing valve, a damper and a trailer control pipeline joint which are communicated, wherein the second reversing valve is communicated with the gas tank; a third pipeline which comprises a second on-off valve, an electric pressure regulating valve and a third on-off valve which are communicated, wherein the second on-off valve is communicated with the gas tank; a fourth pipeline which comprises a tractor control pipeline joint and a fourth on-off valve which are communicated with each other; a fifth pipeline which comprises a fifth on-off valve and a trailer energy supply pipeline joint which are communicated with each other, wherein the fifth on-off valve is communicated with the gas tank, the second reversing valve is connected with a sixth on-off valve; and a seventh on-off valve is connected between the first reversing valve and the trailer energy supply pipeline joint. The test device has the advantages of 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...
