Description

Technical Field

[0001] The utility model belongs to the field of automated processing technology for new energy vehicle parts, and specifically relates to a gas storage type rear suspension C-type bracket for a bus. Background Art

[0002] With increasingly fierce competition in the bus market and growing operational pressure on customers, cost and weight reduction have become urgent common demands across all product lines. Achieving these goals through structural integration of chassis components and material sharing, combined with existing market suspension structures, is becoming increasingly important.

[0003] like Figure 1 、 Figure 2 As shown, the structure of the passenger car's non-independent air rear suspension is as follows: a bracket 101, serving as a guide and load-bearing device, is connected to the axle via U-bolts. An airbag 102 and a shock absorber 103, serving as supporting elements, are mounted on either side of bracket 101. Airbag 102 requires two separate air reservoirs for air supply, requiring a large number of them, making their placement difficult and costly.

[0004] Therefore, although the rear brackets of existing passenger car non-independent suspensions are mostly cavity-type, they only serve as support and guidance, and the cavity space is not fully utilized. Therefore, there is no precedent for designing the internal cavity of the bracket as an air reservoir on existing passenger car rear suspensions. Utility Model Content

[0005] The technical problem to be solved by the utility model is: how to solve the cost and weight problems of the existing rear suspension, and provide a gas storage type rear suspension C-type bracket for buses.

[0006] The technical solution of the utility model is specifically as follows:

[0007] A C-shaped gas storage rear suspension bracket for a bus comprises a hollow bracket, the hollow bracket comprising a bracket body, an axle mounting bracket being provided on the bracket body; gas is stored in a cavity within the hollow bracket, and at least three gas interfaces are provided on the hollow bracket;

[0008] The bracket body comprises an upper body and a lower body. Bolt mounting round tubes for mounting an airbag are welded on the upper body and the lower body. The bolt mounting round tubes are welded to the lower body and the upper body respectively.

[0009] A first gas interface, a second gas interface, a third gas interface and a fourth gas interface are provided on the hollow bracket, wherein the first gas interface, the second gas interface, the third gas interface and the fourth gas interface are all connected to the hollow bracket (14).

[0010] A water discharge interface is provided on the axle mounting bracket of the hollow bracket, and the water discharge interface is used for installing a water discharge device of the bracket type air storage cylinder.

[0011] A blocking plate is provided at the end of the bracket body for blocking both ends of the bracket body. A threaded sleeve for welding is provided on the upper body. The bolt mounting round tube is respectively welded to the threaded sleeve and the circumference of the upper body.

[0012] The bracket body is provided with a left mounting member and a right mounting member capable of fixing the bracket to the axle body. Both the left mounting member and the right mounting member are provided with U-bolt mounting holes, and a supporting bearing plate is provided between the left mounting member and the right mounting member.

[0013] The beneficial effects of the present invention are as follows: the bracket of the present invention is in the form of a hollow C-shaped cavity. After the two ends are sealed, the volume of the internal cavity is larger than the volume of the airbag air reservoir, and can be used as an airbag air reservoir. This eliminates the need for a separate air reservoir and auxiliary bracket and other related components for the entire vehicle, reducing the cost of materials and installation time, and also saving space and reducing weight for the entire vehicle. At the same time, it can also be used as an auxiliary air chamber to improve the comfort of the entire vehicle. BRIEF DESCRIPTION OF THE DRAWINGS
