Description

Technical Field

[0001] The utility model belongs to the technical field of spare tires for trucks and relates to a spare tire fixing device for trucks. Background Art

[0002] A truck spare tire is a spare tire used to replace the main tire of a truck. The specifications and models of a truck spare tire are usually the same as the main tire to ensure smooth installation and use when replacement is needed. Truck spare tires are usually stored at the bottom or rear of the truck for emergency use. Due to the complex road conditions and load conditions of trucks, the quality and performance of truck spare tires are crucial to the safety and stable operation of trucks. When a truck spare tire is fixed at the lower end of the vehicle chassis, if the roll potential energy of the spare tire cannot be effectively released, a series of problems may occur.

[0003] First, the roll potential energy that cannot be released slowly will cause damage to the spare tire itself. The spare tire may age faster due to continuous twisting and friction during long-term swinging and vibration, causing uneven wear on the tire surface and even cracks. This not only shortens the service life of the spare tire, but may also affect driving safety at critical moments due to the decline in tire performance.

[0004] Secondly, this continuous swaying and vibration will also cause additional burden on the chassis and suspension system of the vehicle. The swing potential energy of the spare tire will be transmitted to the chassis and suspension system through the fixing device, which may cause the loosening or damage of related components in the long run, affecting the stability and handling of the vehicle. Therefore, a truck spare tire fixing device is urgently needed to solve the above problems. Utility Model Content

The wheel hub 110 can be connected, fixed and supported by using the fixing frame 120.

[0027] The spare tire body 100 is suspended and installed at the lower end of the vehicle chassis. Two groups of load-bearing rods 150 are provided, and the two groups are respectively arranged at the front and rear sides of the fixing frame 120. The load-bearing rods 150 are air damping rods.

[0028] The two groups of load-bearing rods 150 are respectively connected and fixed to the left and right sides of the vehicle chassis through connecting parts. The load-bearing rods 150 and the locking plate 140 are an integrated structure. The cross-section of the locking plate 140 is a 6-shaped structure. By using two groups of load-bearing rods 150, the swing potential energy generated by the spare tire body 100 during the driving of the vehicle can be released.

[0029] See also Figure 1-Figure 4 , as the first embodiment of the utility model: in order to solve the problem that this continuous swaying and vibration will also cause additional burden on the chassis and suspension system of the vehicle, the swaying potential energy of the spare tire will be transmitted to the chassis and suspension system through the fixing device, which may cause loosening or damage of related components in the long run, affecting the stability and handling of the vehicle. First, when the vehicle vibrates and bumps during driving, its spare tire body 100 will generate roll pressure in different directions at the lower end of the vehicle chassis due to its own weight. Since there are two groups of load-bearing rods 150, the two groups are respectively arranged on the front and rear sides of the fixing frame 120, and the load-bearing rods 150 are a kind of air damping rod. The two groups of load-bearing rods 150 are respectively connected and fixed to the left and right sides of the vehicle chassis through connecting pieces.
