Embodiment Construction

[0025] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0026] The present invention cancels the automatic lifting door or automatic folding door in the prior art, and replaces it with an open door 7, and cancels the air supply system in the original solution. Two air intakes 8 and 9 have been newly added in the body.

[0027] Such as image 3 In the process of vehicle-related performance testing, a large amount of exhaust gas will be discharged from the exhaust pipe 10 of the vehicle, and the exhaust system will generate negative pressure in the pit, and a large amount of exhaust gas will be discharged through the flap. The design of the soundproof room, and the exhaust exhaust pipe 10 of some models will be discharged to the left and right sides of the chamber. figure 2 new air vents in ).

[0028] Compared with the prior art, the prese...

Abstract

The invention relates to a soundproof room of a rotating hub and a use method thereof. The soundproof room is provided with an open door. A soundproof room body is provided with suction openings and is above the ground level. A pit is below the ground level. Rotating hubs, whole vehicle detection devices, are installed in the soundproof room body and the pit. The vehicles to be detected directly enter the soundproof room body from the open door and directly exit from the open door after detection. The soundproof room not only ensures safe protection, satisfies the production requirement and achieves the soundproof and noiseproof effects, but also lowers the costs of investment and maintenance.

Description

technical field [0001] The invention relates to a hub sound insulation room and a hub air supply and exhaust system for vehicle off-line detection equipment, in particular to a hub sound insulation room and a method for using the hub sound insulation room. Background technique [0002] After the whole vehicle comes off the assembly line, relevant inspections will be carried out on the braking and acceleration performance of the whole vehicle. Generally, the entire vehicle factory conducts these inspections in the hub equipment, in order to avoid possible danger, noise and For the impact of exhaust gas generated by high-speed operation on other areas, sound insulation rooms are generally added outside the hub equipment. That is, when the braking and acceleration performance of the whole vehicle is tested on the rotating hub equipment, in order to ensure the safety of the testing vehicle, testing equipment and personnel, the testing equipment and testing vehicles are all in th...
