[0002] At present, the damping of the shock absorber used in passive suspension depends on the elasticity of each valve group; once the valve groups are adjusted and installed, the damping characteristics and damping characteristics The damping performance of the vibrator is also determined. Since its damping is not adjustable, it cannot guarantee that the damping characteristics of the suspension system will change with the change of the vehicle's operating conditions, and it cannot take into account the comfort and handling stability of the car at the same time. seriously affect vehicle performance

Embodiment Construction
[0013] combined with figure 1 The whole shock absorber involved in the present invention is described in detail:
[0014] The shock absorber includes in the figure: oil storage cylinder 1, bottom valve assembly 2, manual adjustment valve assembly 3, working cylinder 4, intermediate cylinder 5, piston valve assembly 6, guide assembly 7 and piston rod 8, all The bottom valve assembly 2 described above is matched with the lower end of the working cylinder 1 and placed at the bottom of the oil storage cylinder 1. The piston valve assembly 6 is matched with the piston rod 8 through threads and placed inside the working cylinder 4. The outer edge of the piston valve assembly 6 is in contact with the working cylinder 1. The inner edge of the cylinder 4 contacts to form a moving pair and the contact surface forms a dynamic seal for the oil. The guide assembly 7 is placed on the upper end of the oil storage cylinder 1 and the working cylinder 4 and cooperates with the inner edges of th...

The invention relates to a part applied to an automobile suspension system and in particular relates to a manually adjusted damp-adjustable shock absorber. The shock absorber comprises an oil storage cylinder, a bottom valve assembly, a manually adjusted valve assembly, a working cylinder, a middle cylinder, a piston valve assembly, a guider assembly and a piston rod; the bottom valve assembly is matched with the lower end of the working cylinder and arranged at the bottom of the oil storage cylinder; the piston valve assembly is matched with the piston rod by use of threads and arranged inside the working cylinder; the outer edge of the piston valve assembly is in contact with the inner side edge of the working cylinder to form a movable pair and the contact surfaces form dynamic seal for an oil liquid; the guider assembly is arranged at the upper ends of the oil storage cylinder and the working cylinder and matched with the inner edges of the oil storage cylinder and the working cylinder to form static seal for the oil liquid, respectively. The manually adjusted damp-adjustable shock absorber is simple in structure, adjustable in damping, capable of well guaranteeing the change of the damping characteristic of the suspension system along with the change of automobile running conditions, and also capable of simultaneously considering the comfort and the operating stability of the automobile.
Description
technical field [0001] The invention relates to a component used in a vehicle suspension system, in particular to a manually adjustable damping adjustable shock absorber in the vehicle suspension system with adjustable damping force. Background technique [0002] At present, the damping of the shock absorber used in passive suspension depends on the elasticity of each valve group; once the valve groups are adjusted and installed, the damping characteristics and damping characteristics The vibration damping performance of the vibrator is also determined. Since its damping is not adjustable, it cannot guarantee that the damping characteristics of the suspension system will change with the change of the vehicle's operating conditions, and it cannot take into account the comfort and handling stability of the vehicle at the same time. Seriously affect vehicle performance. Contents of the invention [0003] The purpose of the present invention is to provide a simple and reasona...
