Abstract
A sub-frame for a car is formed by the welded connection of an upper metal plate and a lower metal plate, wherein one mounting hole is formed at each of the four corners of the sub-frame; overturned edges of the upper and the lower two metal plates are formed in the holes through punching; a metal sheath is flush mounted in each mounting hole; and edges of both ends of each metal sheath are turned outwards and completely cover the overturned edges of the upper and the lower two metal plates in a corresponding hole. In the sub-frame for a car, metal sheaths are flush mounted in the mounting holes and the inner surfaces of the mounting holes become planes, so that after a rubber shock absorbing block is embedded, the quality risks caused by the abrasion of iron cement can be avoided, the phenomena of abnormal noise and displacement caused by abrasion are eliminated, the service lives of parts are prolonged, and the actual safety effect of the safety pieces is achieved.
Description
Technical field
The utility model relates to a kind of automotive parts, particularly a kind of secondary car frame.
Background technology
Secondary car frame is with car propons and driving engine bonded assembly safety member, is again the fulcrum of forward mounting, be slow down front body travel in vibrations critical parts.As shown in Figure 1, secondary car frame 1 is made of welded connection by two metal sheets up and down, at two metal sheets up and down four jiaos a mounting hole 11 is arranged respectively, is to form through the punching press flange.After two metal sheets are welded to connect up and down, in mounting hole, add damping rubber block, so that insert tie bolt.The structure at the mounting hole place of the secondary car frame of prior art as shown in Figure 2, after two metal sheets were welded to connect up and down, corresponding flange 12,13 became the inwall of mounting hole, and its length direction fails to connect healing.So after embedding damping rubber block, the flange of failing to heal, the on the go damping rubber block that can wear and tear, after the damping rubber block wearing and tearing, can cause bolt and hole wall direct friction to produce abnormal sound, and then cause the loosening and displacement of whole subframe, influence the safety of vehicle '.
The utility model content
The purpose of this utility model is to overcome the problem that above-mentioned prior art exists, and a kind of damping rubber block worn-down secondary car frame of avoiding is provided.
The purpose of this utility model is achieved in that a kind of secondary car frame, be made of welded connection by two metal sheets up and down, its four jiaos respectively are provided with a mounting hole, two the flange up and down that is formed by punching is arranged in the hole, be embedded with a metallic sheath in each mounting hole respectively, the two ends outward flanging of metallic sheath is with in the flange of two metal sheets is sealed on fully up and down in the respective aperture.
Secondary car frame of the present utility model since in mounting hole setting-in metallic sheath, make the inside face of mounting hole become the plane.After embedding damping rubber block, can evade the quality risk due to the wearing and tearing of iron glue, to have stopped because of the abnormal sound that wearing and tearing produce, the phenomenon of displacement, prolong the service life of part, really played the safety effect of safety member.
Description of drawings
Fig. 1 is the structural representation of secondary car frame;
Fig. 2 is the A-A sectional structure scheme drawing (prior art) of Fig. 1;
Fig. 3 is the A-A sectional structure scheme drawing (the utility model) of Fig. 1.
The specific embodiment
Referring to Fig. 1, cooperation is referring to Fig. 3, secondary car frame 1 of the present utility model, be made of welded connection by two metal sheets up and down, its four jiaos respectively are provided with a mounting hole 11, two the flange 12,13 up and down that is formed by punching is arranged in the hole, be embedded with a metallic sheath 14 respectively in each mounting hole, the two ends outward flanging of metallic sheath is with in the flange of two metal sheets is sealed on fully up and down in the respective aperture.
Secondary car frame of the present utility model is taked the additional way of technology under the prerequisite of the structure that does not change parts and mould, embedded with metallic sheath at mounting hole, by the interference PROCESS FOR TREATMENT, the flange rivet clasp is in four holes.Thereby make the inside face of mounting hole become the plane.During installation, damping rubber block embeds through lubricated extruding, reduces its ionized space, has really played the effect that safety tightens up.
Claims (1)
1, a kind of secondary car frame, be made of welded connection by two metal sheets up and down, its four jiaos respectively are provided with a mounting hole, two the flange up and down that is formed by punching is arranged in the hole, it is characterized in that: be embedded with a metallic sheath in described each mounting hole respectively, the two ends outward flanging of metallic sheath is with in the flange of two metal sheets is sealed on fully up and down in the respective aperture.
