Description

Technical Field

[0001] The utility model belongs to the technical field of a shock absorber base, and in particular relates to an adjustable shock absorber base suitable for a MacPherson type suspension structure. Background Art

[0002] The McPherson suspension is an important component that elastically connects the frame and the axle. Its structure and performance parameters have a direct impact on the ride smoothness and handling stability of the car. It is one of the most popular independent suspensions today and is generally used for the front wheels of cars. It is an important part of the car's safety structure. The driving control and comfort of the car have always been closely related to the suspension system in the chassis structure, and the simplicity and complexity of the suspension structure also directly determines the cost of car manufacturing. The McPherson independent suspension is one of many suspension systems. It has won wide market application with its simple structure, low cost and decent comfort. However, due to the interference of the transmission shaft on the base of some McPherson shock absorbers, the base has to be designed as a two-piece sheet metal welded on the barrel, which is very bulky and cannot adjust the height of the car body.

[0003] Application number "CN201220414196.5" records "a McPherson-type air spring shock absorber, including a damping shock absorber piston rod, a damping shock absorber outer cylinder, a buffer block, an air spring screw-on seat, an air filling hole, a bladder clamp, an air spring bladder, an upper half of an air spring base, a lower half of an air spring base, an air spring base locking nut, a steering knuckle mounting seat locking nut, a gasket, a steering knuckle mounting seat, a nut, a thrust bearing, and a sealing O-ring."

[0004] The above patent is based on a McPherson-type air spring shock absorber. Since the nonlinear stiffness characteristics of the air spring can meet the vehicle spring stiffness requirements under different road impacts, it can well take into account the vehicle's comfort and handling stability. When the vehicle turns, the air spring assembly and the damping shock absorber outer cylinder are fastened to each other and relatively stationary, and the air spring assembly and the shock absorber piston rod rotate relative to each other. At this time, the multi-layer sealing O-ring embedded in the top seat of the air spring ensures air tightness, and the rotating thrust bearing ensures smooth rotation during turning, thereby solving the rotating seal problem.

[0005] The above patent can facilitate the installation of air spring shock absorbers on vehicles with McPherson suspension, fundamentally solving the actual steering rotation seal problem of McPherson air spring shock absorbers, and greatly improving the driving comfort and handling stability of the vehicle. However, the base of some McPherson shock absorbers is interfered by the transmission shaft, so the base has to be designed as a two-piece sheet metal welded to the barrel, which is very bulky and cannot adjust the height of the vehicle body.

[0016] As a preferred solution of the utility model, the connecting sleeve and the connecting part of the barrel are connected by threads, and the height of the threaded connection is designed to be 30 mm.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

The two first connecting plates are respectively fixed to the two side walls of one end of the fixing seat, and the two second connecting plates are respectively fixed to the two side walls of the other end of the fixing seat, and the two first connecting plates and the second connecting plates are used in conjunction with each other.
