Description

Technical Field

[0001] This utility model relates to the field of spare tire suspension technology, specifically a spare tire suspension device for military tactical vehicles. Background Technology

[0002] In modern military operations, military tactical vehicles undertake critical tasks such as material transport, personnel deployment, and fire support. Their mobility and reliability are crucial to the success or failure of combat operations. As a vital component for military tactical vehicles to cope with sudden tire failures during operation, the performance and design of the spare tire's suspension system directly affect the ease of access to the spare tire, installation stability, and the overall combat effectiveness of the vehicle.

[0003] Traditional spare tire suspension systems for military tactical vehicles often have several shortcomings: In terms of installation stability, some suspension systems do not securely hold the spare tire firmly enough. During vehicle operation, especially when traversing complex terrain or engaging in high-intensity maneuvers, the spare tire is prone to shaking or even falling off, which can damage the vehicle itself and potentially create safety hazards. Regarding ease of access, the height of traditional suspension systems is usually fixed. This means that when attaching or removing the spare tire, personnel need to expend considerable effort to move it. Due to the significant weight of the spare tire, this process is not only time-consuming and labor-intensive but also increases the workload and reduces work efficiency. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 The present invention provides the following technical solution:

[0018] Example 1: A spare tire suspension device for military tactical vehicles includes a mounting plate 1 and a mounting beam 2. A central column 3 is fixedly connected to the center of the front end of the mounting plate 1. A limit block 4 is threadedly connected to the front end of the central column 3. A plurality of positioning rods 5 are evenly arranged around the central column 3, and each positioning rod 5 is fixedly connected to the mounting plate 1. A limit nut 6 is threadedly connected to the front end of each positioning rod 5. A mounting column 13 is fixedly connected to the back side of the mounting plate 1. Two collars 14 are rotatably connected to the outside of the mounting column 13, and a connecting plate 10 is fixedly connected to the outside of each collar 14. An opening 9 is provided at the upper end of the mounting beam 2, and a drive assembly 8 is provided inside the opening 9. The drive assembly 8 includes a screw 83, which is rotatably connected inside the opening 9. One end of the screw 83 is fixedly connected to the output end of the motor 81, which is fixedly connected to the outside of the mounting beam 2. Both ends of the screw 83 are threaded with moving blocks 82. The bottom ends of the two moving blocks 82 are rotatably connected to the top ends of the two connecting plates 10 respectively. A fixed rod 84 is provided on one side of the screw 83. The fixed rod 84 is fixed in the opening 9. The two moving blocks 82 are movably sleeved with the fixed rod 84. The spare tire is adjusted to a suitable height through the drive assembly 8 and the connecting plate 10. There is no need to spend a lot of effort to move the heavy spare tire, which greatly reduces the labor intensity of the staff and improves the work efficiency. At the same time, the outer side of the spare tire is squeezed and clamped by several squeezing blocks 73, which further ensures the stability of the spare tire.

[0019] Guide rods 12 are vertically fixed to the outer sides of both ends of the mounting beam 2. Guide plates 11 are fixedly connected to both sides of the mounting plate 1. The two guide plates 11 are movably connected to the two guide rods 12 respectively. The mounting plate 11 is guided by the guide rods 12 through the movable connection between the guide plates 11 and the guide plates 12 to ensure the stable lifting and lowering of the mounting plate 1.

[0020] In use, the device is mounted at the rear of the vehicle via the mounting beam 2, and a battery is installed at the rear of the vehicle to provide power to the motor 81. When the operator starts the motor 81, the motor 81 drives the screw 83 to rotate. The spirals inside the two moving blocks 82 rotate in opposite directions, so the rotation of the screw 83 will drive the two moving blocks 82 to move towards each other along the screw 83. Then, through the drive of the two connecting plates 10, the mounting plate 1 will be raised and lowered, which can adjust the spare tire to a suitable height. There is no need to spend a lot of effort to move the heavy spare tire, which greatly reduces the labor intensity of the operators and improves work efficiency.

[0021] Example 2, the technical solution of which differs from Example 1 includes: a number of auxiliary components 7 are provided on the outside of the mounting plate 1. Each of the auxiliary components 7 includes a side plate 71. The side plate 71 is fixedly connected to the outside of the mounting plate. A sliding groove 72 is provided on the outside of the side plate 71. A pressing block 73 is movably connected in the sliding groove 72. A bolt 74 is rotatably connected to one side of the pressing block 73. The bolt 74 is threadedly connected to one side of the side plate 71. The outside of the spare tire is pressed and clamped by the pressing blocks 73, thereby further ensuring the stability of the spare tire and preventing the spare tire from falling off and shaking during vehicle operation.

[0022] The width of several extrusion blocks 73 is adapted to the width of the corresponding slide groove 72 to ensure that the extrusion blocks 73 move stably within the slide groove 72;

[0023] Several extrusion blocks 73 are provided with toothed grooves 75 on the side near the mounting plate 1 to increase the friction between the extrusion blocks 73 and the outer wall of the spare tire, thereby strengthening the clamping effect on the spare tire and ensuring the stability of the spare tire.

[0024] In use, the spare tire is suspended on the mounting plate 1 by the central column 3 and several positioning rods 5. Then, the spare tire is clamped by the limiting block 4 and several limiting nuts 6, so that the spare tire is stably suspended on the mounting plate 1. Then, the bolt 74 is rotated, and the bolt 74 drives the extrusion block 73 to move in the slide groove 72. The extrusion block 73 extrudes the outer wall of the spare tire. By clamping the spare tire with several extrusion blocks 73, the stability of the spare tire is further guaranteed, preventing it from falling off or shaking. It can also adapt to spare tires of different sizes, making it more adaptable.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
