The central line of the pneumatic round hole is superposed with the central line of the outer canister shell; the outer canister shell of the automobile vibration absorber comprises an outer canister shell body and a bottom cover which is integrated with the outer canister shell body; the middle of the bottom cover is provided with the pneumatic round hole; the sealing plug comprises a column introduction segment, three reinforcement sheets arranged on the column introduction segment evenly and a column fit segment which is interference fit with the pneumatic round hole at the middle of the bottom cover; and a pneumatic groove is formed between the column introduction segment and the three reinforcement sheets. The automobile vibration absorber pneumatic structure of the utility model adopts the way, which can prolong the service life of the vibration absorber and reduce the cost of the vibration absorber.
Description
Technical field
The utility model relates to automobile bumper inflatable structure.
Background technology
In automotive suspension, the main effect of shock absorber is decay body vibrations and the vibration that suppresses wheel.The decay body vibrations makes the people take advantage of seat more comfortable, improves ride of vehicle; Suppress the vibration of wheel, make vehicle in the enhancing of driving process tire ground connection property, vehicle is convenient to handle, and improves vehicle run stability, ensures the driving safety of automobile.This total external characteristics of shock absorber is by the requirement of vehicle suspension system decision, and the life-span and the in-use performance of the inflatable structure of shock absorber decision shock absorber.The qi of chong channel ascending adversely structure of prior oscillating damper adopts flat oil enveloping structure, bumper urceolus housing only upper end has opening, oil sealing and piston rod interference fit, oil sealing is a Rubber Parts, has dustproof lip, one-way sealing, this structure need be inserted on the dustproof lip of oil sealed with a Plastic Parts when qi of chong channel ascending adversely, charge into nitrogen with special tooling.Because of the pressure of shock absorber is lower than the external world, gas overcomes oil sealing and reports tight power to enter in the shock absorber, when qi of chong channel ascending adversely, Plastic Parts is inserted on the oil sealed lip, has the risk that scratches oil seal lip, the oil sealing easy oil leakage, reduce the service life of shock absorber, bumper urceolus housing needs to adopt the cold rolled precision pipe for guaranteeing positiver sealing, and manufacturing cost is higher.
The utility model content
Technical problem to be solved in the utility model is: a kind of service life of shock absorber, automobile bumper inflatable structure of reduction shock absorber manufacturing cost of improving is provided.
Solve this technical problem, the technical solution of the utility model is: a kind of automobile bumper inflatable structure, it comprises the inflation circular hole of automobile absorber urceolus housing bottom and the sealing bolt of shutoff inflation circular hole, the central lines of the line of centers of described inflation circular hole and urceolus housing.
Described automobile absorber urceolus housing is made up of urceolus enclosure body and the bottom that forms one, and the middle part of bottom has the inflation circular hole.
Described sealing bolt by the cylinder introduction segment, be distributed on three muscle sheets of cylinder introduction segment and form with the cylinder section of cooperation of the inflation circular hole interference fit at bottom middle part, form aeration tank between cylinder introduction segment and three muscle sheets.
The utility model automobile is adopted in such a way with the bumper inflatable structure, beneficial effect is as follows: a, qi of chong channel ascending adversely do not charge into from oil seal lip, but charge into from the inflation circular hole of bumper urceolus housing bottom, oil sealing is injury-free, and prolonged the service life of shock absorber; B, bumper urceolus housing adopt common material to make, and under the situation that guarantees the shock absorber performance, have reduced the cost of shock absorber, have improved the market competitiveness.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done explanation in further detail:
Fig. 1 is the automobile absorber structural representation;
Fig. 2 is a sealing bolt structure for amplifying scheme drawing shown in Figure 1;
Fig. 3 is a bottom cover structure scheme drawing shown in Figure 1;
In Fig. 1, Fig. 2, Fig. 3,1, the urceolus enclosure body; 2, bottom; 3, sealing bolt; 4, clutch release slave cylinder; 5, guides; 6, oil sealing; 7, oil seal seat; 8, piston rod; 9, cylinder cooperates section; 10, muscle sheet; 11, cylinder introduction segment; 12, inflation circular hole.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, a kind of automobile absorber, comprise urceolus enclosure body 1, bottom 2, sealing bolt 3, clutch release slave cylinder 4, guides 5, oil sealing 6, oil seal seat 7, piston rod 8, its bottom is the inflatable structure of automobile with bumper, it comprises the inflation circular hole 12 of automobile absorber urceolus housing bottom and the sealing bolt 3 of shutoff inflation circular hole 12, the bottom 2 of urceolus enclosure body 1 and formation one forms automobile absorber urceolus housings, the middle part of bottom 2 has inflation circular hole 12, the line of centers of inflation circular hole 12 and the central lines of urceolus housing.
Sealing bolt 3 by cylinder introduction segment 11, be distributed on three muscle sheets 10 of cylinder introduction segment 11 and form with the cylinder section of cooperation 9 of inflation circular hole 12 interference fit at bottom 2 middle parts, form aeration tank between cylinder introduction segment 11 and three muscle sheets 10.
The skeleton type oil enveloping structure is adopted in the upper end of automobile absorber, oil sealing 6 is pressed into earlier in the oil seal seat 7, guides 5 and clutch release slave cylinder 4 are housed on piston rod 8, together put into urceolus enclosure body 1, oil seal seat 7 is pressed into gap between guides 5 and the urceolus enclosure body 1, cylinder shell body 1 carries out electric-resistance seam-welding with the oil seal seat seam outside, guarantees reliable intensity and sealing.During shock absorber work, oil sealing has the qi of chong channel ascending adversely lip, and guides matches with it, forms non-return valve function, and fuel return hole is arranged on guides, and shock absorber oil overflows from the gap between guides and the piston rod, flow back into shoe cream room through fuel return hole.Oscillating damper inflation is the bottom of cylinder shell outside, and sealing bolt 3 is pressed into half earlier, makes the qi of chong channel ascending adversely groove conducting of sealing bolt 3, along qi of chong channel ascending adversely groove oiling in shock absorber of shock absorber, after oiling is finished, in shock absorber, charge into the nitrogen of authorized pressure again, after having dashed, the indentation sealing bolt seals.The nitrogen that pours is not influenced by oil sealed, and the nitrogen pressure that charges into is identical with the force value of apparatus settings, is very easy to control and is convenient to regulate.The qi of chong channel ascending adversely pressure consistency is good, good stability, and oiling and the inflation once finish, improved charge efficiency.
The utility model automobile is adopted in such a way with the bumper inflatable structure, and a, qi of chong channel ascending adversely do not charge into from oil seal lip, but charges into from the inflation circular hole of bumper urceolus housing bottom, and oil sealing is injury-free, and prolonged the service life of shock absorber; B, bumper urceolus housing adopt common material to make, and under the situation that guarantees the shock absorber performance, have reduced the cost of shock absorber, have improved the market competitiveness.
