Description

Technical Field

[0001] The utility model relates to a supporting structure, in particular to an adjustable hydraulic spare tire bracket supporting seat. Background Art

[0002] In order to ensure driving safety, heavy trucks need to carry a spare tire in case of damage, leakage or blowout. At present, most heavy trucks use side spare tires or rear spare tires. Some heavy trucks have adopted front hydraulic spare tire brackets, but most of the existing front hydraulic spare tire brackets do not have a tire support mechanism, resulting in severe shaking of the front hydraulic spare tire bracket when the vehicle is driving. Even if some front hydraulic spare tire brackets have added support brackets, they cannot be adjusted to adapt to the tire due to changes in the tire's inflation pressure and cannot play a supporting role. Utility Model Content

[0003] The purpose of the utility model is to provide an adjustable hydraulic spare tire bracket support, which can adapt to the change in the height direction of the tire bottom caused by the change in the tire inflation pressure, reduce the problem of the spare tire bracket shaking due to the tire being suspended during vehicle driving, and increase the fatigue life of the spare tire bracket.

[0004] The utility model is realized by the following technical solutions:

[0005] An adjustable hydraulic spare tire support bracket includes a support bracket frame 301, a rubber protective plate 302, a support panel 303, a rubber pressure plate 304, a standard component group 305, a spare nut 306, a support bolt 307 and a welding nut 308.

[0006] The support frame 301 is welded by reinforcing ribs on both sides and an L-shaped support plate. The support plate is bent from a 10mm steel plate. A bolt mounting hole is provided on the rear end face, which is fixed to the hydraulic spare tire bracket 1 by bolts. Four through holes are arranged in a cross on the upper end face, and welding nuts 308 are welded on the upper surfaces of the left and right holes.

[0007] The rubber protective plate 302 is made of 5mm rubber and is secured to the support panel 303 via a rubber pressure plate 304 and a standard component set 305. The support panel 303 is made of a bent 6mm steel plate and has two weld nuts 308 welded to its bottom. Bolt mounting holes are provided at each end of the support panel 303. The standard component set 305 secures the pressure plate 304, rubber protective plate 302, and support panel 303 together using these bolt mounting holes.

[0008] Four support bolts 307 are screwed through the four through holes arranged in a cross on the upper end surface of the support frame 301. Two of the support bolts 307 are screwed into two welded nuts 308 welded at the bottom of the support panel 303. The two support bolts 307 are screwed with spare nuts 306. The spare nuts 306 are located on the upper surface of the support frame 301.

[0009] The other two support bolts 307 are screwed through the two welding nuts 308 welded on the upper end surface of the support frame 301 .

[0010] The utility model can reduce the shaking problem of the spare tire bracket during vehicle driving, increase the fatigue life of the spare tire bracket, can adapt to the change in the height direction of the tire bottom caused by the change of tire inflation pressure, can reduce tire wear during vehicle driving, and increase the service life of the tire.

[0017] like Figure 1-6 As shown, the utility model is an adjustable hydraulic spare tire bracket support support. The support support 3 is composed of a support support frame 301, a rubber protective plate 302, a support panel 303, a rubber pressure plate 304, a standard part 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 flip arm side of the hydraulic spare tire bracket 1 by bolts to support the tire 2 to prevent the spare tire bracket from shaking when the vehicle is driving. The hydraulic spare tire bracket 1 is fixed to the frame by connecting the support and U-bolts.

[0018] The support frame 301 is welded by reinforcing ribs on both sides and an L-shaped support plate. The support plate is bent from a 10mm steel plate. A bolt mounting hole is provided on the rear end face, which is fixed to the hydraulic spare tire bracket 1 by bolts. Four through holes are arranged in a cross on the upper end face, and welding nuts 308 are welded on the upper surfaces of the left and right holes.

[0019] The rubber protective plate 302 is made of 5mm rubber plate and is fixed to the support panel 303 through the rubber pressure plate 304 and the standard parts group 305. The support panel 303 is made of a bent 6mm steel plate, with bolt mounting holes at both ends and two welding nuts 308 welded to the bottom of the panel.

[0020] The support bracket 3 is installed on the hydraulic spare tire bracket 1. The size of the gap with the tire is changed by adjusting the support bolts 307. When there is a gap between the support bracket 3 and the tire, first rotate the spare nut 306 upward to ensure that there is enough gap between it and the upper surface of the support bracket frame. Adjust the left and right support bolts 307 until the rubber protective plate contacts the tire. Finally, adjust the spare nut 306 and fasten it to the upper surface of the support bracket frame 301.

[0021] Beneficial effects of the utility model:

[0022] 1. The height direction of the hydraulic spare tire bracket support can be adjusted to adapt to the change in the height direction of the tire bottom caused by the change in tire inflation pressure;

[0023] 2. The hydraulic spare tire bracket has a simple structure, easy operation, good workmanship and convenient maintenance;

[0024] 3. The rubber plate fixed on the surface of the hydraulic spare tire bracket support can buffer the impact force generated by the shaking of the spare tire bracket and reduce the wear caused by tire impact and friction.
