DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 The embodiment of the utility model provides a technical solution: an adjustable suspension, comprising a device body 1, the device body 1 comprising a frame 2, a U-shaped bolt 3, a rear axle 4, a height adjustment device 5 and a leaf spring 6, the U-shaped bolt 3 is mounted at the bottom of the frame 2, the rear axle 4 is mounted at the bottom of the U-shaped bolt 3, the height adjustment device 5 is mounted at the top of the rear axle 4, the leaf spring 6 is mounted at the bottom of the frame 2, and the bottom of the leaf spring 6 is located at the top of the height adjustment device 5;

[0024] The height adjustment device 5 comprises a base 7, a screw rod 8, a left-handed threaded slider 9, a right-handed threaded slider 10 and an inclined top block 11. The base 7 is in an L-shaped structure. The left-handed threaded slider 9 and the right-handed threaded slider 10 are both installed on the top of the base 7. The tops of the left-handed threaded slider 9 and the right-handed threaded slider 10 are both in an inclined structure. The inclined top block 11 is installed on the tops of the left-handed threaded slider 9 and the right-handed threaded slider 10. The screw rod 8 is installed on the right end of the top of the base 7. The screw rod 8 is connected with the left-handed threaded slider 9 and the right-handed threaded slider 10 in sequence through threads. The two ends of the screw rod 8 are left-handed and right-handed threads. When adjusting the height, the screw rod 8 is rotated. Because the two ends of the screw rod 8 are left-handed and right-handed threads, the left-handed threaded slider 9 and the right-handed threaded slider 10 can be moved inward or outward at the same time. Further, the left-handed threaded slider 9 and the right-handed threaded slider 10 can push the inclined top block 11. In this way, the height adjustment between the rear axle 4 and the leaf spring 6 can be adjusted.

[0025] Furthermore, a base locating pin 12 is provided at the top of the base 7, and a rear axle locating hole 13 is opened at the bottom of the base 7. The locating pin 12 at the top of the base 7 is used to locate the bottom of the inclined top block 11, and the rear axle locating hole 13 at the bottom of the base 7 is for facilitating the positioning, connection and fixation of the rear axle 4.

[0026] Differently, the inclined top block 11 has a trapezoidal structure, a positioning pin limiting hole 14 is provided at the bottom of the inclined top block 11, and a inclined top positioning hole 15 is provided at the top of the inclined top block 11. The positioning pin limiting hole 14 and the inclined top positioning hole 15 are through-type structures, and the diameter of the inclined top positioning hole 15 is smaller than the diameter of the positioning pin limiting hole 14. The positioning pin limiting hole 14 at the bottom of the inclined top block 11 is for facilitating the insertion of the base locating pin 12 to achieve the purpose of positioning, while the inclined top positioning hole 15 at the top of the inclined top block 11 is for facilitating the insertion, locking and fixing of the leaf spring locating pin 16.

[0027] Specifically, a leaf spring positioning pin 16 is fixed between the leaf spring 6 and the inclined lift block 11 , and the bottom of the leaf spring positioning pin 16 is located in the inclined lift positioning hole 15 . The leaf spring positioning pin 16 can make the connection between the leaf spring 6 and the inclined lift block 11 more firmly.

[0028] Working principle: During operation, the staff adjusts the distance between the rear axle 4 and the leaf spring 6 by rotating the screw 8. Because the two ends of the screw 8 are left-handed and right-handed threads, the left-handed threaded slider 9 and the right-handed threaded slider 10 can move inward or outward at the same time. Further, the left-handed threaded slider 9 and the right-handed threaded slider 10 can push the inclined push block 11. In this way, the height between the rear axle 4 and the leaf spring 6 can be adjusted.

[0029] The components of the utility model are 1, device body; 2, frame; 3, U-shaped bolt; 4, rear axle; 5, height adjustment device; 6, leaf spring; 7, base; 8, screw; 9, left-handed threaded slider; 10, right-handed threaded slider; 11, inclined top block; 12, base locating pin; 13, rear axle locating hole; 14, locating pin limiting hole; 15, inclined top locating hole; 16, leaf spring locating pin. All the components are universal standard parts or components known to those skilled in the art. The structures and principles thereof can be known to those skilled in the art through technical manuals or conventional experimental methods. The problems solved by the utility model are as follows: The vehicle attitude angle design, due to manufacturing errors, the final actual vehicle attitude angle is different from the design theoretical value, which affects the aesthetics of the vehicle, and causes the center of mass of the vehicle to shift, affecting the front and rear axle load distribution, which may affect the vehicle's climbing performance. In addition, it may cause the left and right height difference of the cargo box to tilt, affecting the vehicle's aesthetics and driving safety. The utility model can adjust the vehicle attitude angle to be consistent with the design state through the combination of the above-mentioned components, avoiding the influence of factors such as manufacturing errors on the vehicle attitude angle, and can also adjust the left and right height difference inclination of the cargo box to a consistent level, which is beneficial to improving the vehicle's climbing performance and driving safety.
