Abstract
The utility model discloses a subassembly is covered in shock absorber supporting, including the supporting lid that is dome form, supporting caping end terminal surface is provided with the centre bore that supplies the piston rod to pass through, the flange structure that the open end was provided with outside extension is covered in the supporting, and this flange structure covers in the supporting and forms the buckle that can block at the dust cover port, the buckle card is in the draw -in groove that the dust cover port was located to set up, flange structure adopts and covers stamping forming in the supporting. Through covering the buckle that stamping forming goes out a flange structure in present supporting, the buckle card makes to form between supporting lid and the dust cover and effectively is connected in the draw -in groove of dust cover port department to the abnormal sound because of striking between free drunkenness of dust cover and the spring tray produces has effectively been avoided, zonulae occludens between supporting lid and the dust cover port has eliminated the fit -up gap between dust cover port and the supporting lid.
Description
Technical field
The utility model relates to absorber technical field, in particular to the support cap assembly on a kind of MacPherson type vibroshock.
Background technology
MacPherson type vibroshock is after rotation press closing; a part support cap can be pressed in vibroshock end; it mainly acts on is when vehicle is through convex closure or hollow place; buffer block in vibroshock contacts by compression and between support cap; when buffing pad is compressed into the limit; support cap, for bearing the whole load from buffer block, to protect the oil sealing in vibroshock not damaged, namely plays the effect of one overfill protection. Existing common support lid adopts impact briquetting usually, and the overall wall thickness of support cap is less, causes supporting cover in use, owing to being subject to impact loading repeatedly, it is easy to deforms or destroys and affect the result of use of vibroshock.
Vibroshock is in working process, and when vehicle movement is to severe silt road surface, silt can enter oil sealing from dw oral area, and draws and hinder vibroshock oil sealing, finally causes vibroshock leakage of oil, inefficacy, affects the work-ing life of vibroshock. Existing support cap is due to structural reason, and the fit-up gap after mounting and between dw is relatively big, and silt is easy to enter in vibroshock oil sealing; Further, support cap and dw effectively do not connect after mounting, cause dw port effectively to be fixed, dw freely up and down can move along with vibroshock, in moving process, dw port easily strikes spring tray, thus produces abnormal sound, affects the NVH performance of whole car.
Practical novel content
The purpose of this utility model is the above-mentioned technical problem solved existing for existing support cap, a kind of vibroshock support cap assembly is provided, can effectively increase the strength property of support cap, improve its impact resistance, and formed between energy and dw and be effectively connected, eliminate dw and alter the abnormal sound caused.
For solving the problems of the technologies described above, the utility model have employed a kind of vibroshock support cap assembly, comprise the support cap in circle lid, support cap top end face is provided with for the centre hole that piston rod passes through, described support cap opening end is provided with outward extending turnup structure, this turnup structure forms a card that may be stuck in dw port on support cap and buckles, and described card buckle is in the card groove that dw port is arranged, and described turnup structure adopts impact briquetting on support cap.
Described support cap top is provided with stiffening plate, stiffening plate is provided with the centre hole matched with support cap, is welded to connect between stiffening plate and support cap.
The card that the utility model goes out a turnup structure by impact briquetting on existing support cap is buckled, card buckle is in the card groove of dw port, make to be formed between support cap with dw to be effectively connected, like this when support cap moves up and down under vibroshock piston rod drives, dw can move together along with support cap, thus effectively prevent freely to alter because dw and clash into and the abnormal sound that produces between spring tray, it is to increase the NVH performance of vehicle. In addition, compact siro spinning technology will be carried out between support cap and dw port, eliminate the fit-up gap between dw port and support cap, dw internal space and outside space are effectively isolated by the turnup structure of support cap opening end, such silt is entered in oil sealing by the fit-up gap between dw and support cap with regard to being difficult to, thus effectively improves the work-ing life of vibroshock.
Meanwhile, the one end bearing repeatedly shock action on support cap arranges a stiffening plate, adds the impact resistance of support cap, it is to increase the use properties of support cap.
Accompanying drawing explanation
Fig. 1 is the utility model support cap component assembling view.
Fig. 2 is the utility model structural representation.
I place partial schematic diagram in Fig. 3 Fig. 1.
In figure: 1, piston rod, 2, dw, 3, buffer block, 4, support cap, 5, stiffening plate, 6, dw port, 7, card button, 8, card groove, 9, centre hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Such as Fig. 1 to 3, for a kind of vibroshock support cap assembly, comprise the support cap 4 in circle lid, support cap 4 top end face is provided with for the centre hole 9 that piston rod 1 passes through, described support cap 4 opening end is provided with outward extending turnup structure, and this turnup structure forms a card that may be stuck in dw port 6 on support cap 4 and buckles 7. As shown in Figure 3, an annular slot 8 is set in dw port 6, card button 7 is stuck in the card groove 8 that dw port 6 place is arranged, owing to card buckles 7 for horn-like turnup structure, card button 7 and card groove 8 form an effective baffle structure jointly like this, are effectively isolated in dw 2 internal space and outside space; Described turnup structure adopts impact briquetting on support cap 4. Dw 2 is arranged on outside vibroshock piston rod 1, the card arranging turnup structure at support cap 4 opening end buckles 7, during assembling, card button 7 is stuck in the annular slot 8 in dw port 6, thus support cap 4 is connected with dw 2, like this when support cap 4 moves up and down under vibroshock piston rod 1 drives, dw 2 can move together along with support cap 4, thus effectively prevent because the abnormal sound clashed between spring tray and produce freely altered by dw 2.
In vibroshock, support cap 4 is arranged on piston rod 1, when piston rod 1 moves up and down, directly contacts between support cap 4 with buffer block 3, and and there is an impact forces repeatedly extruded between buffer block 3. By being provided with stiffening plate 5 on support cap 4 top, it is possible not only to the bulk strength performance increasing support cap 4, and can also effectively increase the contact area between support cap 4 and buffer block 3, we know, under same reactive force, active area is more big, the intensity born is more little, can reduce the shock action of buffer block 3 on support cap 4, improves the use properties of support cap 4 further. Stiffening plate is provided with the centre hole 9 matched with support cap, adopts between stiffening plate 5 and support cap 4 and be welded to connect, stiffening plate 5 is fixedly connected on support cap 4.
Specification sheets of the present utility model and accompanying drawing be considered as illustrate property but not restrictive; on the utility model basis; those skilled in the art are according to disclosed technology contents; do not need creative work that some of them technology feature just can be made some to replace and distortion, all in protection scope of the present invention.
