Abstract
The utility model provides a novel bearing and shearing plate spring assembly. The plate spring assembly is provided with flat spring plates and a center positioning bolt, wherein the center positioning bolt penetrates center holes formed on the flat spring plates to fix the flat spring plates into a whole; and a positioning lug boss matched with a balance shaft plate spring seat hole is processed at the periphery of the center hole on the lower end surface of the lowest flat spring plate. In the utility model, the positioning lug boss matched with the balance shaft plate spring seat hole is pressed on the lower end surface of the lowest leaf spring and used for positioning and limiting, which not influences the load-bearing and service performance of vehicles and solves the problem that a center bolt of a leaf spring has high probability of being sheared.
Description
Technical field
The utility model relates to a kind of elastic element of automotive suspension, particularly a kind of novel scissors plate spring assembly of holding.
Background technology
At present, two back axle autotrucies extensively adopt the plane formula steel plate spring assembly, and six square toes center bolts are all adopted in steel spring and balance shaft spring block location; This structure causes the center bolt of back doube bridge steel spring to be cut off in abominable operating environment easily.
The utility model content
The technical matters that the utility model solves: provide a kind of novel scissors plate spring assembly of holding, at positioning boss that matches with the balance shaft spring block of the center bolt knock hole place of bottom a slice steel spring compacting.By positioning boss location, spacing, neither influence vehicle carrying and in-use performance, also solved spring centre bolt easily by the problem of cutting off.
The technical solution adopted in the utility model: a kind of novel scissors plate spring assembly of holding, it comprises planar leaf springs and centralized positioning bolt two parts.Described centralized positioning bolt is fixed by the centre hole that is shaped on the planar leaf springs and is one, is suppressed with a positioning boss that matches with balance shaft spring block hole at the center bolt knock hole place of the bottom a slice leaf spring of planar leaf springs.The positioning boss of described leaf spring is rounded, is positioned at the top of the bolt cap of centralized positioning bolt.
The utility model has compared with prior art solved the problem that the centralized positioning bolt is cut off easily, and structural change is little, and processing is simple, is easy to assembling.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the leaf spring structural representation of band positioning boss of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1,2 a kind of embodiment of the present utility model is described.
A kind of novel scissors plate spring assembly of holding, have planar leaf springs 1 and centralized positioning bolt 2, centralized positioning bolt 2 is fixed by the centre hole that is shaped on the planar leaf springs 1 and is one, and the centre hole periphery, lower surface of described planar leaf springs 1 bottom a slice leaf spring is suppressed with a circular positioning boss 3 that matches with balance shaft spring block hole.During assembling, positioning boss 3 is positioned at balance shaft spring block hole, and is positioned at the top of the bolt cap 4 of centralized positioning bolt 2.
The utility model cooperates with the knock hole of balance shaft spring block by positioning boss 3 and plays certain location, position-limiting action; alleviate the shearing force on the centralized positioning bolt 2; protect the centralized positioning bolt effectively, thereby solved the vehicle problem that the leaf spring center bolt is easily cut off when heavy duty.
