Abstract
The utility model relates to a back steel plate spring for preventing the dislocation of an automobile with double axles, which belongs to a steel plate spring of a suspending frame system of an automobile. The utility model discloses the back steel plate spring for preventing the dislocation of an automobile with double axles. The utility model comprises a main spring and an auxiliary spring. A limiting block is arranged between the main spring and the auxiliary spring, and a concave-convex groove on the end part of the auxiliary spring is matched with a concave-convex groove of an adjacent spring sheet. Because the limiting block and each concave-convex groove of the auxiliary spring are added between the springs, the auxiliary spring of the steel plate spring can not dislocated easily. The service life of the plate spring is prolonged, noise is lowered, and the service life of a connecting piece on an automobile frame is prolonged.
Description
(1) technical field
The utility model belongs to the steel spring of automobile suspension system, the anti-dislocation of particularly a kind of diaxon automobile rear leaf spring.
(2) background technology
Existing diaxon automotive use rear-suspension system light plate spring auxiliary spring does not have the mistake proofing bit function, its weak point is that vehicle traveling process light plate spring auxiliary spring easily produces inconsistent phenomenon, reduce the steel spring life-span on the one hand, on the other hand, auxiliary spring and vehicle frame upper connector rub, produce noise, reduce the attaching parts life-span.
(3) summary of the invention
The purpose of this utility model is to provide a kind of diaxon automobile rear leaf spring auxiliary spring to have the mistake proofing bit function, prolongs the leaf spring life-span, reduces noise, improves the vehicle frame upper connector life-span.
The purpose of this utility model is achieved in that
The utility model discloses the anti-dislocation of a kind of diaxon automobile rear leaf spring, have main spring and auxiliary spring, between master, the auxiliary spring limiting stopper is arranged, there is concavo-convex groove the auxiliary spring end, and adjacent reed concavo-convex groove matches.
Because increase limiting stopper and each sheet of auxiliary spring have concavo-convex groove between the spring, thereby make the steel spring auxiliary spring be difficult for dislocation, prolong the leaf spring life-span, reduce noise, the raising vehicle frame upper connector life-span.
(4) description of drawings
Fig. 1 is master of the present utility model, auxiliary spring integral structure scheme drawing
Fig. 2 is the concavo-convex groove structural representation of auxiliary spring end
Fig. 3 is the structural representation of limiting stopper
Among the figure, 1. main spring, 2. auxiliary spring, 3. limiting stopper
(5) specific embodiment
Below in conjunction with accompanying drawing present embodiment is made specific description: the rear leaf spring of present embodiment, form by main spring 1 and auxiliary spring 2, limiting stopper 3 is arranged between main spring and the auxiliary spring, the structure of limiting stopper 3 is as shown in Figure 3.The 3rd non-clamp end of auxiliary spring and the 4th to the 6th both ends are all carried out indent and are handled, as shown in Figure 2, upper surface, lower surface have a concave, convex groove respectively, the concavo-convex groove of upper and lower auxiliary spring matches, prevent the auxiliary spring dislocation, avoid the vehicle frame upper connector to rub, reduce noise, prolong the attaching parts life-span.
Claims (1)
1. the anti-dislocation of a diaxon automobile rear leaf spring has main spring and auxiliary spring, and it is characterized in that: between master, the auxiliary spring limiting stopper is arranged: there is concavo-convex groove the auxiliary spring end, and adjacent reed concavo-convex groove matches.
