Abstract
The utility model relates to a novel steel plate spring with variable cross section. The novel steel plate spring comprises at least four leaf spring main bodies and leaf spring end parts connected with the main bodies. Four leaf spring main bodies are fixedly connected with one another by bolts; the end parts between a leaf spring 1 and a leaf spring 2 are connected with each other by a rolling ear; a near-end of the end part of the leaf spring 1 is of the collapse bending shape; and the end parts of a leaf spring 3 and a leaf spring 4 are of the collapse bending shape. In the utility model, an end part gasket is canceled; and the steel plate spring can reduce the friction among the leaf springs when in use, so as to improve the abrasive resistance of the steel plate spring, improve the stability of the arc height of the steel plate spring and effectively prolong the service life of the steel plate spring.
Description
Technical field
The utility model relates to a kind of leaf spring, relates in particular to a kind of novel variable-section steel sheet spring.
Background technique
Former leaf spring end construction form production technology is: rolling-punching-heat treatment-general assembly;
The gasket type structure is adopted in former leaf spring end, the easy premature wear of plastic spacer in this structural type, thus the leaf spring camber obviously reduces, and influences the user and uses.
The model utility content
The technical problems to be solved in the utility model is: a kind of novel variable-section steel sheet spring is provided, increases the wear resistance of leaf spring, effectively improve leaf spring working life.
In order to overcome the defective that exists in the background technique, the technological scheme that its technical problem that solves the utility model adopts is: a kind of novel variable-section steel sheet spring, comprise and have four reed main bodys at least, and the leaf end that is connected with main body, by bolt that four reed main bodys are fixedly connected, reed one is connected by grasswort with end between the reed two, and the end near-end of reed one is the curved shape that collapses, and reed three is the curved shape that collapses with reed four ends.
According to another embodiment of the present utility model, a kind of novel variable-section steel sheet spring further comprises between each reed and is provided with pad.
According to another embodiment of the present utility model, a kind of novel variable-section steel sheet spring further comprises between described reed main body and the leaf end and is provided with fixture block, by fixture block leaf end is fixed.
According to another embodiment of the present utility model, a kind of novel variable-section steel sheet spring comprises that further the reed one and the outer surface of reed four are provided with backing plate.
The utility model has solved the defective that exists in the background technique, its beneficial effect is: the utility model end construction adopts the end bending formula of collapsing, the cancellation end pad, leaf spring produces friction at process light plate sheet that uses and sheet steel itself, increased its wear resistance, strengthened the stability of the camber of leaf spring, effectively improved leaf spring working life, complained in early days thereby reduce the user.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Wherein: 1, grasswort, 2, reed one, 3, clamp, 4, reed two, 5, reed three, 6, reed four, 7, backing plate, 8, bolt, 9, pad.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, a kind of novel variable-section steel sheet spring, comprise and have four reed main bodys at least, and the leaf end that is connected with main body, by bolt 8 that four reed main bodys are fixedly connected, reed 1 is connected by grasswort 1 with end between the reed 24, and the end near-end of reed 1 is the curved shape that collapses, and reed 35 is the curved shape that collapses with reed 46 ends.Wherein, be provided with pad 9 between each reed, reed 1 is provided with backing plate 7 with the outer surface of reed 46.
For improving leaf end stability, be provided with fixture block 3 between reed main body and the leaf end, by fixture block 3 leaf end is fixed.
The utility model cancellation leaf end pad, leaf spring reed in the process of using rubs with reed itself and reduces, and has increased its wear resistance, has strengthened the stability of the camber of leaf spring, effectively improves leaf spring working life.
The utility model spring end structural type production technology: at first prismatic steel plate rolling is become the steel plate of variable cross section, the steel plate to variable cross section carries out moulding then, i.e. end moulding grasswort, and the end kinking structure that collapses, steel plate is whole to be bent; Steel plate after the moulding is heat-treated heat; At last each reed is fitted together, each reed is fixed by bolt, fixture block.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
