Abstract

The utility model provides an automobile damper belonging to the technical field of automobiles and being used for solving the problems that not only is the cost increased, but also the weight of the whole camper is increased because the traditional damper is generally and additionally provided with a nonmetal vibration insulation cushion between a spiral spring and a spring plate. The automobile damper comprises a piston rod, a cylinder barrel and a spiral spring sleeved on the cylinder barrel and the piston rod, wherein one end of the piston rod is accommodated inside the cylinder barrel; a spring plate is fixed on the piston rod; one end of the spiral spring supports against the spring plate, and the other end of the spiral spring is fixed on the outer wall of the cylinder barrel; and the spiral spring is provided with a transition segment supporting against the spring plate only when the spiral spring moves; and a protecting jacket playing a vibration insulation role in wrapped on the transition segment. The protecting jacket plays roles of vibration insulation and wear reduction and is low in cost and small in weight, so that the cost and the weight of the damper can be reduced.

Description

A kind of vehicle shock absorber
Technical field
The utility model belongs to automobile technical field, relates to a kind of vehicle shock absorber.
Background technique
Extensively adopt hydraulic damper in the automobile suspension system.Its principle is, when vehicle frame and vehicle bridge are done reciprocal relative movement and when moving back and forth in the cylinder barrel of piston at vibration damper, the fluid in the vibration damper housing just flows into another inner chambers from inner chamber through some narrow holes times without number.At this moment, the interior friction of the friction of liquid and inwall and fluid molecule just forms the damping force to vibration.
Vibration damper comprises piston rod, cylinder barrel, helical spring, spring seat, and helical spring is enclosed within outside piston rod and the cylinder barrel, and an end and spring seat lean.In the damping process, helical spring is play on piston rod, makes helical spring and spring seat produce friction, noise.In order to reduce the noise that friction and relative movement produced between helical spring spring and the damper spring dish, for this reason, the vibration damper of present low and middle-end vehicle installs nonmetal vibration isolator usually additional between helical spring and spring holder.Not only increase cost but install vibration isolator additional, and make the weight of whole vibration damper also increase.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed the lighter vehicle shock absorber of a kind of weight.
The purpose of the utility model can realize through following technical proposal: a kind of vehicle shock absorber; Comprise piston rod, cylinder barrel and be enclosed within cylinder barrel and piston rod on helical spring; Piston rod one end is contained in cylinder barrel inside, is fixed with spring holder on the described piston rod, and described helical spring one end is against on the spring holder; The other end is fixed on the cylinder barrel outer wall; It is characterized in that described helical spring has the changeover portion that when motion could lean with spring holder, be enclosed with the protecting jacket of vibration isolation effect on the described changeover portion.
By compression the time, changeover portion also can be resisted against on the spring holder, makes helical spring and spring holder bump like this or friction and noise at helical spring; Reduce the performance of vibration damper, behind parcel protecting jacket on the changeover portion, avoided the direct collision or the friction of changeover portion and spring holder; Protecting jacket plays vibration isolation, anti-attrition effect; And the protecting jacket cost is low, and weight is little, can reduce the cost and the weight of vibration damper.
In above-mentioned vehicle shock absorber, described protecting jacket two ends are provided with the glue that itself and helical spring are fixed.Glue is optional after protecting jacket is moved suitable position to, smears fixedly glue at the protecting jacket two ends with AB glue commonly used in the engineering, makes protecting jacket ability extended immobilization at changeover portion, durable in use.
In above-mentioned vehicle shock absorber, described protecting jacket thickness range is 0.5mm~1mm.0.5mm the protecting jacket of~1mm thickness can play vibration isolation, anti-attrition effect, does not influence helical spring elasticity again.
In above-mentioned vehicle shock absorber, described protecting jacket is processed by wear-resisting, withstand voltage and rubber-like nonmetallic material.Flexible nonmetallic material make that the vibration isolating effect of protecting jacket is better, and wear-resisting, the withstand voltage working life that increases protecting jacket.
In above-mentioned vehicle shock absorber, described nonmetallic material can be rubber, plastics, nylon or resin.Rubber, plastics, nylon and resin all have certain abrasion resistance and elasticity, and all belong to the material of lighter weight, and raw material are also cheap on market, the protecting jacket low cost of manufacture.
Compared with prior art, this vibration damper utilizes protecting jacket to substitute vibration isolator, not only can reduce cost, and also helps the lightweight of vibration damper.
Description of drawings
Fig. 1 is the structural representation of this vibration damper.
Fig. 2 is that helical spring and the position of spring holder and protecting jacket in this vibration damper concerns schematic representation.
Among the figure, 1, piston rod; 2, cylinder barrel; 3, helical spring; 4, spring holder; 5, protecting jacket.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
Like Fig. 1, shown in Figure 2, this vehicle shock absorber comprise piston rod 1, cylinder barrel 2 and be enclosed within cylinder barrel 2 and piston rod 1 on helical spring 3, piston rod 1 one ends are contained in cylinder barrel 2 inside, piston rod 1 can move up and down in cylinder barrel 2.Be fixed with spring holder 4 on the shaft of piston rod 1, spring holder 4 is along with piston rod 1 moves together.Helical spring 3 one ends are against on the spring holder 4, and the other end is fixed on cylinder barrel 2 outer walls, and when piston rod 1 goed deep into cylinder barrel 2 inside, spring holder 4 descended, and helical spring 3 is squeezed.
Helical spring 3 has the changeover portion that when motion could lean with spring holder 4, and changeover portion receives helical spring 3 degree affect that is squeezed, and when helical spring 3 was squeezed to a certain degree, changeover portion can lean with spring holder 4 fully.For guaranteeing when changeover portion and spring holder 4 lean, not produce friction, noise, on changeover portion, be enclosed with the protecting jacket 5 of vibration isolation effect.
Protecting jacket 5 in the present embodiment adopts wear-resisting, withstand voltage and the rubber-like nylon material is processed, this protecting jacket 5 light weights, and cost is low, and durable in use.Certainly, protecting jacket 5 materials can use rubber, plastics or resin to replace.Be assembled to the changeover portion of helical spring 3 at protecting jacket 5 after, be coated with the glue that itself and helical spring 3 are fixed, adopt the AB glue fixing usually at protecting jacket 5 two ends.The thickness of protecting jacket 5 should be to be advisable about 0.7mm, the too thick elasticity that then influences helical spring 3.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as piston rod 1, cylinder barrel 2, helical spring 3, spring holder 4, protecting jacket 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain the essence of the utility model more easily; It all is contrary with the utility model spirit being construed to any additional restriction to them.
