However, the suspension device with adjustable installation angle of the main spring has a different way of adjusting the proportional adjustment of the stiffness direction by adjusting the angle between the overall bushing and the outer tube. Relative rotation, the adjustment angle is limited and the universal type is not strong

Embodiment Construction
[0025] Such as Figure 1 to Figure 5 As shown, a suspension adjustment member structure with adjustable main spring angle is mainly composed of three parts, namely a pair of rubber main springs 1, an inner tube 2 and an outer tube 3, and a pair of rubber main springs 1 are connected by plugging Assembled into a suspended main spring by way of assembly, the inner tube 2 has an interference fit with the inner ring of the suspended main spring, and the outer tube 3 has an interference fit with the outer ring of the suspended main spring; the outer tube 3 is pressed into the suspended outer frame.
[0026] A pair of rubber main springs 1, inner tube 2 and outer tube 3 are assembled together by plugging and interference fit to ensure the stability of the structure during the suspension adjustment process, without the need to keep the structure stable for a long time.
[0027] The inner pipe 2 and the outer pipe 3 are made by machining of cast metal materials.
[0028] The pair of ...

The invention discloses a suspension adjustment part structure with adjustable main spring angle, which is composed of a pair of rubber main springs, an inner tube and an outer tube, the pair of main springs are assembled into a suspension main spring by plugging, and the inner tube Interference fit with the inner ring of the suspended main spring, interference fit between the outer tube and the outer ring of the suspended main spring; the main spring is composed of an outer connector, an inner connector, and a rubber main spring, and the inner connector is located On the inner side, a pair of main springs are interference-fitted with each other through the inner connector, and are interference-fitted with the outer tube through the outer connector. The inner tube is inserted into the inner connector and has an interference fit. The outer tube is pressed into various suspension inside the exoskeleton. The invention breaks up the vulcanized parts of the suspension assembly and disassembles them into a pair of main springs assembled with inner and outer connecting parts, so that the angle adjustment between the two main springs can be realized. By adjusting the assembly method, the stiffness ratio adjustment can be quickly realized, greatly Saves part time for NVH tuning. The separation of the main spring and the main body of the suspension also reduces the specification of the vulcanization mold, which is convenient to manufacture and the delivery time is short.
Description
technical field [0001] The invention relates to a suspension adjustment component structure with adjustable main spring angle, which belongs to the technical field of vehicle suspension adjustment. Background technique [0002] Bushing mounts are a common structure of mounts. In the mount adjustment stage, once the trial production vulcanization mold is locked, the change of mount stiffness performance can only be realized by adjusting the rubber hardness, but the proportional relationship of stiffness in the three directions is basically impossible. The only way to change is to reopen the vulcanization mold and change the angle and structure of the main spring. [0003] Mount NVH adjustment is an important link in the pre-development of mounts. Due to the need for multiple rounds of parts, parts replacement and retesting, the general period is long and the cost is high. [0004] Prior art 1 discloses a modular hydraulic mount structure, including an assembly bracket and a ...
