Abstract
The utility model relates to a kind of built-in damper damping device.Be arranged on piston rod (1), be between piston rod (1) and clutch release slave cylinder (2), comprise the piston shoes (3) being arranged on piston rod (1) two ends, between described two piston shoes (3), spring (4) is set, wherein piston shoes (3) are fixedly installed on piston rod (1), and another piston shoes (3) can move along piston rod (1).The utility model along piston rod smooth-going slip freely, can not have friction lever phenomenon, would not have noise yet after being equipped with two nylon piston shoes.
Description
Technical field
The utility model relates to a kind of built-in damper damping device, is applied to vibration damper technical field.
Background technique
Vibration damper is divided into epicoele and cavity of resorption, is wherein provided with piston rod in epicoele, wherein arranges damping device in epicoele, and its effect played carried out energy-absorbing buffering before vibration damper is stretched to the limit.
Existing built-in buffer unit structure form and defect thereof are: 1) built-in spring upper end is stuck on clutch release slave cylinder, and lower end is unsettled, if easily there is friction piston bar when spring is done badly or between piston rod and clutch release slave cylinder, gap is too small to produce noise;
2) clutch release slave cylinder may be strutted during existing built-in compression deformation of the spring and produce draining phenomenon, cause the phenomenons such as force value shakiness, idle running;
3) existing built-in spring needs to be pressed into clutch release slave cylinder, installs and wastes time and energy very much, have a strong impact on manufacturing efficiency.
Model utility content
The utility model is for above-mentioned defect, and object is to provide that a kind of structure is simple, function admirable, effectively can carry out the built-in damper damping device of energy-absorbing buffering.
The technical solution adopted in the utility model is for this reason: the utility model is arranged on piston rod (1), be between piston rod (1) and clutch release slave cylinder (2), comprise the piston shoes (3) being arranged on piston rod (1) two ends, between described two piston shoes (3), spring (4) is set, wherein piston shoes (3) are fixedly installed on piston rod (1), and another piston shoes (3) can move along piston rod (1).
Described spring (4) outside is arranged with guide sleeve (5).
Described guide sleeve (5) comprises guide sleeve one (51) and guide sleeve two (52), and wherein guide sleeve one (51), guide sleeve two (52) are fixed on the piston shoes (3) of both sides respectively.
The utility model has the advantages that: 1) the utility model along piston rod smooth-going slip freely, can not have friction lever phenomenon, would not have noise yet after being equipped with two nylon piston shoes;
2) built-in spring of the present utility model perfectly solves draining problem;
3) built-in spring of the present utility model is directly easily put into, and substantially increases working efficiency;
4) the utility model further arranges guide sleeve, the setting of guide sleeve achieves guiding during spring movement, and guide sleeve is fixedly installed, therefore to further ensure in spring movement process and and contact can not be produced between piston rod and clutch release slave cylinder, therefore can not produce noise, ensure that the working life of damping device.
In sum, buffer unit structure of the present utility model is simple, and only need add two piston shoes can realize, and has good using effect through use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is I enlarged view in Fig. 1.
1 be piston rod, 2 be clutch release slave cylinder in figure, 3 be piston shoes, 4 be spring, 5 for guide sleeve;
51 be guide sleeve one, 52 is guide sleeve two.
Embodiment
The utility model is arranged on piston rod 1, be between piston rod 1 and clutch release slave cylinder 2, comprise the piston shoes 3 being arranged on piston rod 1 two ends, between described two piston shoes 3, spring 4 is set, wherein piston shoes 3 are fixedly installed on piston rod 1, and another piston shoes 3 can move along piston rod 1.
Guide sleeve 5 is arranged with outside described spring 4.
Described guide sleeve 5 comprises guide sleeve 1 and guide sleeve 2 52, and wherein guide sleeve 1, guide sleeve 2 52 are fixed on the piston shoes 3 of both sides respectively.
Guide sleeve 5 of the present utility model is arranged on piston shoes 3 two ends, as long as because spring 4 two ends are restricted, spring 4 will be subject to effective guiding in movement process, ensures that spring 4 can move by straight carrying out in movement process.
Piston shoes 3 of the present utility model adopt nylon material to make, and it can slide freely, and nylon material friction factor is low, with low cost, are easy to manufacture, and contact is level and smooth, further reduces noise.
Claims (3)
