Abstract
Description
Technical Field
[0001] This utility model relates to a support structure, specifically an adjustable hydraulic spare tire bracket support. Background Technology
[0002] To ensure driving safety, heavy-duty trucks need to carry a spare tire in case of tire damage, leaks, or blowouts. Currently, most heavy-duty trucks use side spare tires or rear spare tires, and some heavy-duty trucks have adopted front-mounted hydraulic spare tire carriers. However, most existing front-mounted hydraulic spare tire carriers lack tire support mechanisms, causing significant shaking when the vehicle is in motion. Even if some front-mounted hydraulic spare tire carriers have added support brackets, they cannot adjust to the tire due to changes in tire inflation pressure, thus failing to provide support. Utility Model Content
[0003] The purpose of this invention is to provide an adjustable hydraulic spare tire bracket support that can adapt to changes in tire inflation pressure that cause changes in the tire bottom height direction. This can reduce the problem of spare tire bracket swaying during vehicle operation due to the tire being suspended in the air, and increase the fatigue life of the spare tire bracket.
[0004] This utility model is achieved through the following technical solution:
[0005] An adjustable hydraulic spare tire bracket support includes a support frame 301, a rubber protective plate 302, a support panel 303, a rubber pressure plate 304, a standard parts group 305, a spare nut 306, a support bolt 307, and a welding nut 308.
[0006] The support frame 301 is welded from two reinforcing ribs and an L-shaped support plate. The support plate is made of 10mm steel plate bent. The rear end face is provided with bolt mounting holes and is fixed to the hydraulic spare tire bracket 1 by bolts. The upper end face is provided with four through holes in the front, back, left and right.
[0007] The rubber protective plate 302 is made of 5mm rubber sheet and fixed on the support panel 303. Two welding nuts 308 are welded to the bottom of the support panel 303.
[0008] The support bolts 307 pass through four through holes on the upper surface of the support frame 301 from the bottom. The two support bolts 307 on the left and right sides cooperate with two welded nuts 308 welded to the bottom of the support panel 303. The two bolts are also tightened with spare nuts 306, which are located on the upper surface of the support frame 301. The two support bolts 307 at the front and rear are cooperated with two ordinary nuts located on the upper surface of the support frame 301.
[0009] Furthermore, the support panel 303 is made of 6mm steel plate bent into a Z-shape, with bolt mounting holes at both ends. Bolts and nuts pass through the bolt mounting holes at both ends of the rubber pressure plate 304 and the support panel 303 to fix the rubber protective plate 302 onto the support panel 303.
[0010] This invention can reduce the problem of spare tire bracket swaying during vehicle operation, increase the fatigue life of the spare tire bracket, adapt to changes in tire bottom height caused by changes in tire inflation pressure, reduce tire wear during vehicle operation, and increase tire life.

[0016] Figure 6 The supporting frame diagram. Detailed Implementation
[0017] like Figure 1-6 As shown, this utility model is an adjustable hydraulic spare tire bracket support.
[0018] The support bracket 3 is composed of a support bracket frame 301, a rubber protective plate 302, a support panel 303, a rubber pressure plate 304, a standard parts group 305, a spare nut 306, a support bolt 307, a welding nut 308, and other components. It is installed on the lower end of the tire on the tilting arm side of the hydraulic spare tire bracket 1 by bolts to support the tire 2 and prevent the spare tire bracket from shaking when the vehicle is moving. The hydraulic spare tire bracket 1 is fixed to the frame by connecting brackets and U-bolts.
[0019] The support frame 301 is welded from two reinforcing ribs and an L-shaped support plate. The support plate is made of 10mm steel plate bent into shape. The rear end face is provided with bolt mounting holes and is fixed to the hydraulic spare tire bracket 1 by bolts. The upper end face is provided with four through holes, and the upper surface of the left and right holes is fitted with spare nuts 306.
[0020] The rubber protective plate 302 is made of 5mm rubber sheet and is fixed to the support panel 303 by the rubber pressure plate 304 and standard parts assembly 305. The support panel 303 is made of 6mm steel plate bent into a Z-shape and has bolt mounting holes at both ends. Two welding nuts 308 are welded to the bottom of the support panel 303.
[0021] The support bracket 3 is installed on the hydraulic spare tire bracket 1. The gap between the support bracket 3 and the tire 2 is changed by adjusting the support bolt 307. When there is a gap between the support bracket 3 and the tire 2, first turn the spare nut 306 upward to ensure that there is enough gap between it and the upper surface of the support bracket frame 301. Adjust the left and right support bolts until the rubber protective plate 302 contacts the tire 2. Finally, adjust the spare nut 306 to tighten it to the upper surface of the support bracket frame 301.
[0022] This utility model has the following features:
[0023] 1. The height of the hydraulic spare tire support bracket is adjustable to accommodate changes in tire bottom height caused by changes in tire inflation pressure.
[0024] 2. Simple structure, easy operation, good manufacturability, and convenient maintenance;
[0025] 3. The rubber plate fixed on the support surface can buffer the impact force generated by the swaying of the spare tire bracket, and reduce the wear caused by tire impact and friction.
