The connecting structure is simple in whole, convenient to realize and capable of fastening the connection between the piston (2) and the piston rod (1), therefore, the condition that the piston falls off from the piston rod when the vibration amplitude of the damper is large is avoided.

Description

Be used for the linkage structure between vehicle shock absorber piston and the piston rod
Technical field
The utility model relates to the vibration damper of automobile, specifically is the linkage structure that is used between vehicle shock absorber piston and the piston rod.
Background technique
Along with the continuous development of society, people are increasingly high to performance requirements such as the power character of automobile, Economy, braking, control stability, smoothnesss.In order to quicken the decay of automobile vibration, improve the smoothness of automobile running, mounting dampers seems still for necessary in automobile.Vibration damper is mounted in a damping member between car body and the road wheel; Its effect is the vibration of decay car body and the unlimited increase that stops resonance situation lower body amplitude; Vibration damper can reduce the amplitude and the vibration number of body oscillating, thereby can prolong the fatigue life of elastic element and improve the travelling comfort that the personnel of riding.Vibration damper is when work; Vibration when it mainly is used for suppressing bounce-back after the spring absorbing and from the impact on road surface, through uneven road surface the time, though vibration absorbing spring can be filtered the vibration on road surface; But spring self also has to-and-fro motion, and vibration damper is exactly the jump that is used for suppressing vibration absorbing spring.
Piston and piston rod are as the vitals in the vibration damper, and they play an important role in the vibration damping process, and whether piston and piston rod no-float, and this is concerning that can vibration damper proper functioning.Yet existing vibration damper generally just is located at the connection of carrying out on the piston rod between the two with piston sleeve; And the fixing device that does not adopt other to assist; When the vibration damper Oscillation Amplitude was big, piston was prone to come off on the piston rod, thereby makes vibration damper lose vibration-damping function.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology; Being connected between the fastening piston of a kind of ability and the piston rod is provided, thereby piston is used for the linkage structure between vehicle shock absorber piston and the piston rod from what piston rod came off when avoiding the vibration damper Oscillation Amplitude big.
The purpose of the utility model mainly realizes through following technological scheme: be used for the linkage structure between vehicle shock absorber piston and the piston rod; Comprise piston rod, piston, valve seat and nut; Said piston rod one end is provided with the outside thread with the nut inner thread coupling, and said nut sleeve is located at the threaded end of piston rod, and said piston and valve seat all are set on the piston rod; And form interference fit between valve seat and the piston rod, piston is between valve seat and nut.
Said upper cover of piston rod is provided with star spring valve plate and circulation valve block, and said star spring valve plate opposite end surface contacts with the valve block that circulates with valve seat respectively, and the said circulation valve block other end of touching star spring sheet end face that connects contacts with piston.The utility model is provided with the ocsillator strenght between star spring sheet available buffer piston and the valve seat, avoids because of hard collision cause piston or valve seat damage.When the utility model is arranged in the clutch release slave cylinder of vibration damper, the circulation valve block be convenient to the clutch release slave cylinder inner fluid with piston in circulate.
Said upper cover of piston rod is provided with throttle valve plate, baffle plate and pad, and said throttle valve plate contacts with piston, and pad contacts with nut, and the opposite end surface of said baffle plate contacts with pad with throttle valve plate respectively.The purpose that this practicality is provided with throttle valve plate be for the fluid that limits the piston of flowing through too much; The purpose that baffle plate is set is in order to separate throttle valve plate and pad; Avoid the utility model when vibration throttle valve plate opposite end surface all stressed excessive and damage; The purpose that pad is set is for rigid connection the between cushioning fender and the nut, thereby avoids baffle plate to damage.
Compared with prior art, the utlity model has following advantage: the utility model comprises piston rod, piston, valve seat and nut, and piston rod is provided with threaded end; Nut sleeve is located at the threaded end of piston rod; Valve seat and piston all are set on the piston rod, and piston is between valve seat and nut, and valve seat and nut can carry out spacing to piston; The linkage structure that nut and valve seat are fastening between piston and the piston rod, thus piston comes off from piston rod when avoiding the vibration damper Oscillation Amplitude big.
Description of drawings
Fig. 1 is the utility model embodiment's a decomposition texture schematic representation.
The pairing name of reference character is called in the accompanying drawing: 1, piston rod, 2, piston, 3, valve seat, 4, nut, 5, the star compression spring, 6, the circulation valve block, 7, throttle valve plate, 8, baffle plate, 9, pad, 10, stop collar, 11, cushion collar.
Embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is done further to specify, but the mode of execution of the utility model is not limited thereto.
Embodiment:
As shown in Figure 1; Be used for the linkage structure between vehicle shock absorber piston and the piston rod; Comprise piston rod 1, piston 2, valve seat 3, nut 4, star spring valve plate 5, circulation valve block 6, throttle valve plate 7, baffle plate 8 and pad 9, piston rod 1 one ends are provided with the outside thread with nut 4 internal threads coupling, and nut 4 is set in the threaded end of piston rod 1; Valve seat 3 be set on the piston rod 1 and and piston rod 1 between form interference fit, piston 2 is set on the piston rod 1 and between valve seat 3 and nut 4.Star spring valve plate 5 all is set on the piston rod 1 with circulation valve block 6, and star spring valve plate 5 opposite end surfaces contact with circulation valve block 6 with valve seat 3 respectively, and circulation valve block 6 other end of contact star spring sheet 5 end faces relatively contacts with piston 2.Throttle valve plate 7, baffle plate 8 and pad 9 all are set on the piston rod 1; Throttle valve plate 7 one end faces contact with piston 2; Pad 9 one end faces contact with nut 4; The opposite end surface of baffle plate 8 contacts with pad 9 with throttle valve plate 7 respectively, and promptly throttle valve plate 7, baffle plate 8 and pad 9 are arranged between piston 2 and the nut 4, and sets gradually from piston 2 to nut 4.Star spring valve plate 5, circulation valve block 6, throttle valve plate 7 and pad 9 are processed by rubber, and baffle plate 8 is processed by plastic cement.
Also be arranged with stop collar 10 and cushion collar 11 on the piston rod 1; Stop collar 10 all forms interference fit with piston rod 1 with cushion collar 11; Present embodiment is when using; Stop collar 10 is arranged on the upper end of valve seat 3, and cushion collar 11 is arranged on the upper end of stop collar 10, and valve seat 3 bigger displacement occurred with piston 2 when stop collar 10 can avoid valve seat 3 to come off with cushion collar 11 on piston rod 1.
