Description

Technical Field

[0001] This utility model belongs to the technical field of commercial vehicle braking systems and relates to a universal air reservoir band assembly. Background Technology

[0002] In the commercial vehicle sector, trucks typically employ pneumatic braking systems. GB 7258-2017, "Technical Conditions for Safe Operation of Motor Vehicles," requires that motor vehicles have a reliable service braking system, with automobiles requiring dual-circuit or multi-circuit service braking.

[0003] Currently, air pressure braking systems on the market are designed with four circuits: front axle service brake, rear axle service brake, parking brake, and auxiliary air supply. Therefore, most vehicles have 3 to 4 air tanks, and heavy trucks require even more. Vehicle ground clearance varies; some vehicles require space for water sprayers, others have height and width restrictions, and some components cannot extend beyond the upper wing surface of the chassis. Air tanks can be arranged laterally or longitudinally. Due to the required braking gas capacity and overall vehicle layout limitations, the diameters and lengths of the multiple air tanks used in a single vehicle will differ. This necessitates the use of different clamps to secure air tanks of varying diameters. When different vehicle models use air tanks of different diameters, the entire air tank clamp assembly must be redesigned, resulting in a large variety of clamp types, a significant design workload, low clamp versatility, and limitations on mass production of components, thus increasing both material and design costs.

[0004] In existing technologies, such as Figure 1 As shown, the gas cylinder 4 is fixed to the gas cylinder bracket by a clamp assembly. The clamp assembly consists of clamp pins 2 installed at both ends of the clamp. The two ends of the clamp 1 are connected by clamp pins 2 and bolts 3. Different clamps are used for gas cylinders of different diameters. There are many types of parts, which makes it inconvenient to use and lacks universality. Summary of the Invention

[0005] This utility model provides a universal gas storage cylinder clamp assembly that can be matched and installed with various gas storage cylinders of different diameters.

[0006] To solve the technical problem, the present invention adopts the following technical solution: a universal gas storage cylinder clamp assembly, including a clamp, one end of which is fixedly connected to a first U-shaped connecting bracket, and the other end is fixedly connected to at least two second U-shaped connecting brackets at certain intervals. The first U-shaped connecting bracket and the second U-shaped connecting bracket are provided with connecting holes, and the first U-shaped connecting bracket and the second U-shaped connecting bracket are configured for snap-fit connection; in use, the first U-shaped connecting bracket and the second U-shaped connecting bracket are fixedly connected by bolt connectors.

[0007] Furthermore, the outer width of the first U-shaped bracket is smaller than the inner cavity width of the second U-shaped connecting bracket, or the inner cavity width of the first U-shaped bracket is larger than the outer width of the second U-shaped connecting bracket.

[0008] Furthermore, the first U-shaped connecting bracket is welded or riveted to the hoop.

[0009] Furthermore, the second U-shaped connecting bracket is welded or riveted to the hoop.

[0010] The beneficial effects of this utility model are as follows: This utility model can adapt to various sizes of air tanks through the cooperation of the first U-shaped bracket and the second U-shaped connecting bracket, and can match and install various air tanks of different diameters, thus improving versatility; When using this utility model, there is only one structure during vehicle installation, so there will be no assembly errors, fewer assembly parts, and improved assembly convenience; This utility model uses standard parts for fastening, eliminating the clamp pins of the prior art, which can significantly reduce material costs.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] refer to Figures 2-8 A general-purpose gas storage cylinder clamp assembly includes a clamp 1. One end of the clamp 1 is fixedly connected to a first U-shaped connecting bracket 5, and the other end is fixedly connected to two second U-shaped connecting brackets 6 at certain intervals. The first U-shaped connecting bracket 5 and the second U-shaped connecting bracket 6 are provided with connecting holes 8, and the first U-shaped connecting bracket 5 and the second U-shaped connecting bracket 6 are designed for snap-fit connection. In use, the first U-shaped connecting bracket 5 and the second U-shaped connecting bracket 6 are fixedly connected by external bolt connectors passing through the connecting holes 8. The bolt connectors are bolts 3 and nuts 9.

[0022] In this invention, the number of the second U-shaped connecting brackets 6 is not limited to two; more than two can also achieve the purpose. The optimal second U-shaped connecting brackets 6 are 2-4 on a single hoop 1. In actual operation, the number of the second U-shaped connecting brackets 6 is selected according to actual needs.

[0023] In this invention, the outer width L1 of the first U-shaped connecting bracket 5 is smaller than the inner cavity width L2 of the second U-shaped connecting bracket 6; or the inner cavity width of the first U-shaped bracket 5 is larger than the outer width L2 of the second U-shaped connecting bracket 6. When using the first U-shaped bracket 5 and the second U-shaped connecting bracket 6, only one needs to be able to fit into the inner cavity of the other. The specific size of the first U-shaped bracket 5 and the second U-shaped connecting bracket 6 is selected according to actual needs.

[0024] In this utility model, the first U-shaped connecting bracket 5 is welded or riveted to the hoop 1.

[0025] In this utility model, the second U-shaped connecting bracket 6 is welded or riveted to the hoop 1.
