Abstract
The utility model relates to a steel spring plate used for an automobile suspension part. A bulge (2) is arranged at the center position at one side face of the steel spring plate (3), and a groove (1) is arranged at the position at the other side face oppositely to the bulge (2). Compared with the present steel spring plate, the effective section of the steel spring plate is increased and the stress concentration is reduced; therefore, the steel spring plate has strong anti-cracking property. When the steel spring plate needs to be replaced, a U-shaped bolt does not need to be taken down; so long as the loosening distance of a nut on the U-shaped bolt is slightly larger than the sum of the height of the bulge on the steel spring plate and the depth of the groove, the steel spring plate can be drawn out from and placed into the stacked steel spring plates; therefore, the steel spring plate is more convenient to be replaced compared with the present steel spring plate.
Description
Affiliated technical field
The utility model relates to a kind of spring plate of automotive suspension part.
Background technology
The steel spring of existing automotive suspension part is formed by stacking by a plurality of spring plates, each spring plate is provided with a centre hole, and spring plate is fixed together by the tie bolt that is installed in described centre hole, two " U " shape bolts (also claiming staple) in the tie bolt left and right sides across spring plate.In China, the steel spring phenomenon of rupture usually appears in various autotrucies.Promptly found early as indivedual spring plate fractures, must be laid down " U " shape bolt fully, could take out spring plate from tie bolt and change; Because of screw thread corrosion or damage in using, for laying down " U " shape bolt, have to often " U " shape bolt or connected balance seat are destroyed, cause the certain economic loss.Do not found early that as indivedual spring plate fractures autotruck will be put in order the fracture of group steel spring soon, causes the vehicle bridge lack of equilibrium, truck body tilts even overturns, and very easily causes the serious consequence of car crash.
Investigation finds that the steel spring fracture appears at the spring plate central hole mostly.Tracing it to its cause, is because centre hole has reduced the free area of spring plate, has reduced the ability to bear of steel plate central area to reverse stress; There is stress concentration in central hole simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile spring plate, and this spring plate can not only prevent himself fracture, and changes conveniently.
For achieving the above object, the utility model spring plate is provided with projection at the center position of a side, and the position relative with projection in the another side is provided with groove.The centre hole that promptly replaces the former installation tie bolt of spring plate with projection and groove.
Because projection is compared with the centre hole of former installation tie bolt with the structure of groove, the increase of the free area of spring plate, stress concentration reduces, so the utility model is compared with existing spring plate and had stronger anti-breaking fragility.When needs are changed spring plate, need not lay down " U " shape bolt, as long as make the nut loosening distance on " U " shape bolt be slightly larger than the height of projection on this spring plate and the degree of depth sum of groove, spring plate can be extracted out from the spring plate that is stacked together and put into, so the utility model is compared more convenient replacing with existing spring plate.
Description of drawings
Fig. 1 is the front view of first kind of embodiment of the utility model.
Fig. 2 is Fig. 1 cutaway view.
The front view of the another kind of embodiment of Fig. 3 the utility model.
Fig. 4 is the cutaway view of Fig. 3.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described.
As shown in Figures 1 to 4, the center position of the utility model spring plate 3 in a side is provided with projection 2, and the position relative with protruding 2 in the another side is provided with groove 1, promptly replaces the centre hole of the former installation tie bolt of spring plate with projection and groove.Projection and groove cooperatively interact with groove on the adjacent spring plate and projection, are superimposed and promptly are combined into one group of steel spring.Groove 1 and projection 2 on the preferably same spring plate can cooperatively interact on shape, size, the processing of being more convenient for like this.Add man-hour, stamp out a groove, will form a projection simultaneously in the another side in spring plate one side, only need finishing slightly, groove is matched with projection,, groove and projection on the adjacent springs steel plate are cooperatively interacted as long as drift is identical with Sheet Metal Forming Technology.
Claims (1)
1. anti-fracture spring plate of automobile, it is characterized in that: the center position of this spring plate (3) in a side is provided with projection (2), and the position relative with projection (2) in the another side is provided with groove (1).
