The helical spring (9) can buffer the acting force of a piston to the bottom valve so as to prevent the piston or the bottom valve from being damaged.

Description

The bottom valve that is used for vibration damper inner sealing clutch release slave cylinder
Technical field
The utility model relates to the vibration damping equipment of automobile, specifically is the bottom valve that is used for vibration damper inner sealing clutch release slave cylinder.
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 shock-absorbing and from the impact on road surface, through uneven road surface the time, though the shock-absorbing spring can filter the vibrations on road surface; But spring self also has to-and-fro motion, and vibration damper is exactly the jump that is used for suppressing the shock-absorbing spring.
Vibration damper comprises clutch release slave cylinder; The lower ending opening of clutch release slave cylinder is through the bottom valve sealing; The existing bottom valve that is used to seal the clutch release slave cylinder lower ending opening is simple in structure, and when the piston rod movement in the clutch release slave cylinder, piston rod can make between bottom valve and the piston the active force of piston hard collision takes place; This just is prone to make bottom valve or piston to cause damage, thereby can have influence on the normal use of vibration damper.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, and the impact force of a kind of ability damper piston to bottom valve is provided, thus the bottom valve that is used for vibration damper inner sealing clutch release slave cylinder of avoiding piston or bottom valve to damage.
The purpose of the utility model mainly realizes through following technological scheme: the bottom valve that is used for vibration damper inner sealing clutch release slave cylinder; Comprise stationary axle and be set in pressure-bearing pad, sealing valve block, throttle valve plate, foot valve seat, compensation valve block and the helical spring on the stationary axle from the bottom to top in order; The lower end of said stationary axle is provided with fastening termination; The upper end of stationary axle is provided with outside thread; The upper end of stationary axle is arranged with nut, and said nut is provided with the internal thread with stationary axle outside thread coupling, and helical spring upper end apical grafting is in the lower end surface of nut.
Be provided with the packing ring that is set on the stationary axle between said pressure-bearing pad and the sealing valve block.Packing ring is used to separate pressure-bearing pad and sealing valve block, and the impact force between pressure-bearing pad and the sealing valve block is cushioned.
Said pressure-bearing pad, packing ring, sealing valve block, throttle valve plate and compensation valve block all are embedded in the foot valve seat, and said helical spring is arranged on the upper-end surface of foot valve seat.Pressure-bearing pad, packing ring, sealing valve block, throttle valve plate and compensation valve block are embedded in the foot valve seat, so, can make the utility model compact structure, are convenient to the fixing of the utility model.
Said stationary axle is a bolt.Bolt meets the structure of the utility model stationary axle, selects for use bolt as stationary axle, is convenient to the selection of manufacturing.
Compared with prior art; The utlity model has following advantage: the utility model comprises stationary axle, pressure-bearing pad, sealing valve block, throttle valve plate, foot valve seat, compensation valve block, helical spring and nut; Adopt said structure, overall structure is simple, is convenient to realize; When the utility model receives the impact force of piston; Helical spring can cushion the impact force of piston, and this is avoided the utility model and piston generation hard collision and damages, thereby avoids damaging the normal use that influences vibration damper because of the utility model or piston.
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, foot valve seat, 2, stationary axle, 3, nut, 4, the pressure-bearing pad, 5, packing ring, 6, the sealing valve block, 7, throttle valve plate, 8, the compensation valve block, 9, helical spring.
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; The bottom valve that is used for vibration damper inner sealing clutch release slave cylinder; Comprise foot valve seat 1, stationary axle 2, nut 3, pressure-bearing pad 4, packing ring 5, sealing valve block 6, throttle valve plate 7, compensation valve block 8 and helical spring 9, wherein, pressure-bearing pad 4, packing ring 5, sealing valve block 6, throttle valve plate 7, foot valve seat 1, compensation valve block 8 and helical spring 9 are set on the stationary axle 2 from the bottom to top in order; The lower end of stationary axle 2 is provided with fastening termination; Fastening termination contacts the cross-section area of the area of end face greater than 4 perforation of pressure-bearing pad with pressure-bearing pad 4, so, can avoid pressure-bearing pad 4 to come off from stationary axle 2.Pressure-bearing pad 4, packing ring 5, sealing valve block 6, throttle valve plate 7 and compensation valve block 8 all are embedded in the foot valve seat 1, and helical spring 9 is arranged on the upper-end surface of foot valve seat 1.The upper end of stationary axle 2 is provided with outside thread, and nut 3 is set in the upper end of stationary axle 2, and the upper end apical grafting of helical spring 9 is in the lower end surface of nut 3, and nut 3 is provided with the internal thread with stationary axle 2 outside threads coupling.The structure characteristic that meets stationary axle 2 because of bolt; The stationary axle 2 preferred bolts that adopt; The fastening termination of stationary axle 2 then is the head of bolt, and pressure-bearing pad 4, packing ring 5, sealing valve block 6, throttle valve plate 7, foot valve seat 1, compensation valve block 8 and 9 of helical springs are set on the screw rod of bolt.
As stated, then can well realize the utility model.
