Abstract
The utility model relates to a novel shock absorber working cylinder, and relates to the novel shock absorber working cylinder of an automotive suspension shock absorber with a buffering function. The novel shock absorber working cylinder comprises a working section which is matched with a shock absorber piston, a buffering section which is matched with a limiting structure on a shock absorber piston rod and a transitional section which is used for connecting the working section and the buffering section. The working section and the buffering section are of a cylinder shape, the inner diameter of the working section is larger than the inner diameter of the buffering section, and the transitional section is of a frustum shape. When the novel shock absorber working cylinder is used, the frustum-shaped transitional section and the limiting structure on the piston rod form annular gap throttling with the through-flow area continuously decreasing, namely annular gap damping is formed, or weak hydraulic buffering is formed. Due to the fact that a plurality of grooves which are distributed along the periphery are arranged between the transitional section and the buffering section, orifice throttling is formed, namely orifice damping is formed, namely strong buffering with the buffering function gradually increasing is formed. The structure of the novel shock absorber working cylinder is improved, and so that a hydraulic damping shock absorber forms a hydraulic buffering structure at a tension limiting position.
Description
Technical field
The utility model relates to a kind of new type vibration isolator clutch release slave cylinder, especially a kind of new type vibration isolator clutch release slave cylinder that is used to constitute the automotive suspension vibration damper with pooling feature.
Background technique
Vibration damper is the important composition parts of automotive suspension, and its performance directly influences ride of vehicle, riding comfort, control stability and driving safety.The driving cycle complicated and changeable may run into for vibration damper is adapted to, the rigid impact of damper piston and its guide sleeve when avoiding the limit of stretch position, so need damping mechanism be set in vibration damper limit of stretch position.And existing vibration damper clutch release slave cylinder, structure as shown in Figure 1, its clutch release slave cylinder only has the identical active section of internal diameter, can't form the hydraulic cushion structure in vibration damper limit of stretch position.
Summary of the invention
The purpose of this utility model provides a kind of new type vibration isolator clutch release slave cylinder, makes the hydraulic damping vibration damper can form the hydraulic cushion structure in the limit of stretch position.
The purpose of this utility model is achieved through the following technical solutions: the new type vibration isolator clutch release slave cylinder is characterized in that: this clutch release slave cylinder comprises: the active section that matches with damper piston, the breeze way that matches with limit structure on the shock absorber piston rod, the changeover portion that is used to connect active section and breeze way; Described active section, breeze way are cylindrical shape, and the internal diameter of active section is greater than the internal diameter of breeze way, and changeover portion is a taper type.
Several are set along circumferential equally distributed groove between changeover portion and breeze way.
The cross-section size of described groove is successively decreased to the breeze way direction vertically successively from changeover portion.
The beneficial effects of the utility model are: the utility model adopts said structure, during use, limit structure device on taper type changeover portion and the piston rod forms flow area ever-reduced annulus throttling, and annulus damping just promptly forms weak hydraulic cushion.On the other hand, owing between changeover portion and breeze way, be provided with, form orifice restriction, small damping just, the i.e. strong buffering that strengthens gradually of buffer function along circumferential equally distributed several trough.The cross-section size of groove is successively decreased successively vertically from changeover portion to the breeze way direction and is progressively reduced vertically, the big cross-section size end of groove is positioned near taper type changeover portion terminal point, the overwhelming majority that is groove is in breeze way, so these grooves have also constituted the transition of strong and weak buffering.This new type vibration isolator clutch release slave cylinder structure makes the hydraulic damping vibration damper form the hydraulic cushion structure in the limit of stretch position.
