Description

Technical Field

[0001] The invention belongs to the technical field of vehicle suspension system installation methods, and specifically proposes a spatial triangular shock absorber unit structure installation method. Background Art

[0002] When a car is driving, it relies on shock absorbers to reduce vertical and lateral forces. The traditional shock absorber installation method can only rely on the structure of the shock absorber itself to resist the lateral force during the vehicle's driving. If the road conditions are large in lateral force, the shock absorber with the traditional installation method will be severely damaged, resulting in oil leakage, etc., which greatly reduces the life of the shock absorber.

[0019] Advantages and effects:

[0020] The second shock absorber (2) is installed in such a manner that the lower end of the second shock absorber (2) is fixed to the connecting end (10) of the right front lower swing arm (A) of the vehicle, the upper end of the second shock absorber (2) is fixed to the front vehicle body connecting frame (5), and the upper end of the second shock absorber is inclined 10°-40° inwardly of the second axis O2.

[0021] The first shock absorber (1) is installed in such a manner that the lower end of the first shock absorber (1) is fixed to the connecting end (9) of the right rear lower swing arm (B) of the vehicle, the upper end of the first shock absorber (1) is fixed to the rear vehicle body connecting frame (8), the upper end of the first shock absorber (1) is inclined 10°-40° outward of the second axis, and the installation positions of the second shock absorber (2) and the first shock absorber (1) present a spatial triangular structure.

[0022] The installation of the shock absorber on the right side is mirror-symmetrical to that on the left side.

[0023] The lower end of the third shock absorber (6) is fixed to the connecting end (12) of the left front lower swing arm (C) of the vehicle, the upper end of the third shock absorber (6) is fixed to the front vehicle body connecting frame (5), and the upper end of the third shock absorber (6) is inclined 10°-40° inwardly of the second axis.

[0024] The lower end of the fourth shock absorber (7) is fixed to the connecting end (13) of the left rear lower swing arm (D) of the vehicle, the upper end of the fourth shock absorber (7) is fixed to the rear vehicle body connecting frame (8), the upper end of the fourth shock absorber (7) is inclined 10°-40° to the outside of the second axis, and the installation positions of the third shock absorber (6) and the fourth shock absorber (7) present a spatial triangular structure.

[0025] The spatial triangular shock absorber unit structure installation method of the present invention utilizes the triangular support structure to allow the shock absorber to fully utilize the mechanical properties of the two-force rod structure to resist the overturning moment during the vehicle body running (such as Figure 2From the direction shown, it can also be called an X-shape, and the X-shape is actually an extension of the triangle, so the X-shape also has the same characteristics). The overturning moment is resisted by the damping force of the shock absorber instead of using the structure of the shock absorber itself, which is a way that damages the shock absorber. Moreover, the spatial triangular suspension structure installation method is much more effective in reducing the overturning moment than the traditional suspension structure installation method. The above are all effects based on passive shock absorber units. If the spatial triangular shock absorber unit structure of the present invention is installed with an active shock absorber unit, such as on some steeper roads, the height of the active suspension can be changed so that the interior of the car always remains level. For example, when a vehicle passes through some bumpy roads, the protrusion will hit the chassis of the vehicle. At this time, the stroke of the active suspension can be adjusted to raise the chassis of the vehicle to ensure that the chassis of the vehicle will not be damaged.

[0026] In summary, the spatial triangular shock absorber unit structure installation method of the present invention avoids using the structure of the shock absorber itself to resist the lateral force, but uses the damping of the shock absorber to reduce the lateral force. This structure provides greater lateral stability for the vehicle and reduces the damage to the shock absorber itself. The new structure of the present invention has one more shock absorber to support on the same side than the traditional installation structure, and the vehicle suspension structure also resists vertical force better than the traditional suspension structure, thereby improving the safety and comfort of vehicle driving.

The shock absorber on one side presents a spatial triangular structure, and the shock absorber on the other side is installed in a mirror-symmetrical manner.

[0055] The spatial triangular structure of the shock absorbers on the same side is that the second shock absorber (2) and the first shock absorber (1) are inclined inwardly by 10°-40° toward the first axis O1, so that the two shock absorbers present a triangular structure in space.

[0056] The shock absorber on the other side is installed in a mirror-symmetrical manner, and the installation method of the shock absorber on the right side is in a mirror-symmetrical structure with the installation method of the shock absorber on the left side.

[0059] In order to facilitate the calculation of the change trend of the roll force and vertical force of the shock absorber at various angles, the resultant force of the spring stiffness and damping force of the passive suspension shock absorber is set to a constant value of 58800 N. Taking the second shock absorber (2) as an example, the influence of the change of its tilt angle on the force change is studied.

[0060] (1) First fix the second shock absorber (2) to the second axis O2 at an angle of 10°, and then adjust the second shock absorber (2) to the first axis O1 at 10°, 20°, 30°, and 40°. The lateral forces at each angle are: 1773N, 3492.1N, 5105.3N, and 6563.2N. The vertical forces are: 57026.9N, 54414.5N, 50148.6N, and 44359N. The trend is as follows: Figure 6 .1.

[0061] (2) First fix the second shock absorber (2) to the second axis O2 at an angle of 20°, and then adjust the second shock absorber (2) to the first axis O1 at 10°, 20°, 30°, and 40°. The lateral forces at each angle are: 3492.1N, 6878N, 10055N, and 12926.5N. The vertical forces are: 54414.5N, 51921.7N, 47851.3N, and 42327N. The trend is as follows: Figure 6 .2.

[0062] (3) First fix the second shock absorber (2) to the second axis O2 at an angle of 30°, and then adjust the second shock absorber (2) to the first axis O1 at 10°, 20°, 30°, and 40°. The lateral forces at each angle are: 5105.3N, 10055N, 14700N, and 18898N. The vertical forces are: 50148.6N, 47851.3N, 44100N, and 39008.7N. The trend is as follows: Figure 6 .3:

[0063] (4) First fix the second shock absorber (2) to the second axis O2 at an angle of 30°, and then adjust the second shock absorber (2) to the first axis O1 at 10°, 20°, 30°, and 40°. The lateral forces at each angle are: 6563.2N, 12926.5N, 18898N, and 28953.4N. The vertical forces are: 44359N, 42327N, 39008.7, and 34505.2N. The trend is as follows: Figure 6 .4:

[0064] In summary, the triangular structure installation method of the shock absorber of the present invention can adjust the inclination angle of the shock absorber to the second axis O2 according to the installation space at the vehicle suspension system, and can also make the shock absorber tilt to the first axis O1 at a certain angle to present a spatially staggered triangular installation structure. This installation structure has higher stability. With the above structure, through the triangular structure installation method of the shock absorber, the shock absorber can make full use of the mechanical properties of the two-force rod structure to resist the overturning moment during the driving process of the vehicle body, making the vehicle body more stable and greatly improving the effect of vehicle body smoothness. The above are all effects based on passive shock absorber units. If the spatial triangular shock absorber unit structure of the present invention is installed with an active shock absorber unit, it has better effects and more functions than the passive shock absorber unit. For example, some roads with steeper slopes can change the stroke of the active shock absorber unit so that the interior of the vehicle always remains level.
