Detailed Description
The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.
As shown in fig. 1 and 2, the upper support structure of the dual-channel front shock absorber for the vehicle comprises a main support 1, an upper limiting plate 2, a lower limiting plate 3 and a rubber main spring 4, wherein the rubber main spring 4 is formed by vulcanizing the upper limiting plate 2, the main support 1 and a rubber body 5 and independently transmits spring force;
three threaded holes 11 are uniformly distributed in the main bracket 1, and the threaded holes 11 are of self-tapping structures, so that the strength requirement is met, and the material cost and the assembly cost of a bolt or nut assembly structure are saved;
the upper limiting plate 2 is provided with a bowl-shaped upper groove 21; a bowl-shaped lower groove 51 is formed below the rubber body 5, the lower limiting plate 3 is arranged in the lower groove 51, and the top end of the lower limiting plate 3 is connected with the bottom end of the upper limiting plate 2 in a press riveting manner; the middle parts of the upper and lower limiting plates 2 and 3 are provided with through holes 6 and are communicated up and down through the through holes 6;
in order to better meet the requirements of weight and strength of the vehicle type structure, the main bracket 1 is made of SAPH440 material;
in order to meet the strength requirement, the upper limiting plate 2 and the lower limiting plate 3 are made of SAPH370 materials, the thickness of the upper limiting plate 2 is 2.3mm, the thickness of the lower limiting plate 3 is 2.6mm, and the plate thickness can reach 4.9mm after assembly;
in order to further improve the comfort, different rubber rigidities can be arranged on different paths according to different transmission paths of the vibration absorber force and the spring force of the vibration absorber piston rod vibration, and the purpose of separating vibration isolation is achieved through different colloid bearing.
Three loads in the shock absorber of the automotive suspension system: damper force, cushion block force, spring force; most of McPherson front suspension strut models in the market adopt a spring and damper integrated strut structure with integrated force transmission and damping functions, the integrated structure bears the interaction force between a transmission wheel and a vehicle body, the vehicle model with the structure has a single force transmission path, and the spring force and the damping force share a channel, so that the damping force and the spring force are mutually interfered, the strut of the damper is easily influenced greatly by the spring force, an oil seal fails in advance, oil leaks or abnormal sound occurs, the damping force during large impact can influence the fluctuation of the spring force, and the influence on the bearing service life of the McPherson front strut is also large;
