Technical field
The present invention relates to commercial vehicle spring suspension structure more particularly to a kind of two-chip type plate spring structures, belong to traffic work
Has technical field.
Background technique
Domestic commercial vehicle mostly uses longitudinal Leaf Spring Suspension at present, and leaf spring is applied in longitudinal Leaf Spring Suspension
Widest a kind of elastic element, if it is the approximation etc. that wide by dry plate but Length discrepancy alloy spring piece is composed
The spring beam of intensity, when running car, the load on vehicle frame is passed on load box by leaf spring, then is passed in vehicle bridge, during which by
In leaf spring flexible deformation and play buffer function.Leaf spring structure is simple, low in cost, easy to maintenance, and can rise
To the effect of guiding, the friction between piece and piece can also have certain damping action.But commercial vehicle rigid axle suspension uses
Leaf spring have the shortcomings that weight is big, comfort is poor.Development of automobile increasingly payes attention to energy-saving and environmental protection, safety, while customer
Higher to the requirement of commercial vehicle comfort, the application of leaf spring does not meet commercial vehicle technology trends increasingly.Using compound
Material leaf spring replaces leaf spring, will become a kind of novel development trend of domestic automobile industry.There is partial automobile in the country at present
Manufacturer have begun set about carry out composite material plate spring research and development, composite material in terms of obtained effectively
Achievement, such as a kind of plate spring for vehicle disclosed in Chinese patent literature CN205089870U, for another example Chinese patent literature
A kind of composite panel spring structure disclosed in CN106402222A.This composite material plate spring is one chip leaf spring, and this
The bearing capacity of one chip leaf spring is not so good as leaf spring.
Summary of the invention
Therefore, the purpose of the present invention is to overcome the defects in the prior art, and leaf spring weight can be mitigated by providing one kind, together
When solve the problems, such as the two-chip type plate spring structure of one chip leaf spring bearing capacity deficiency.
To achieve the goals above, a kind of two-chip type plate spring structure of the invention, main spring including metal material and folded
It is placed on the auxiliary spring of the composite material below the main spring, the centre of the main spring and auxiliary spring, which passes through center and connects bolt, to be connected
It connects, two hoop components are respectively arranged at the position by two close end of the main spring and auxiliary spring；The hoop component includes opening
The upper positioning lathe dog and lower positioning lathe dog of down-set gate plate are held, the lower positioning lathe dog connects bolt by auxiliary spring and connects
It is connected to the lower section of the auxiliary spring, the upper positioning lathe dog above covers on the main spring, auxiliary spring and lower positioning lathe dog wherein,
Two side plates of the upper positioning lathe dog are bolted by clamp connection respectively with two side plates of lower positioning lathe dog.
The center connection bolt is disposed through the gasket between the main spring and auxiliary spring.
Clamping is there are two silencing pad between the main spring and auxiliary spring, two silencing pads be located at the main spring with
The end positions of the auxiliary spring.
The silencing pad is adhered to the upper surface of the auxiliary spring.
The region for the center connection bolt to be arranged of the main spring and auxiliary spring is flat segments.
The region for the silencing pad to be arranged of the main spring and auxiliary spring is flat segments.
By adopting the above technical scheme, two-chip type plate spring structure of the invention, when bearing lesser load, only main spring work
Make, as load is constantly increasing, auxiliary spring is started to work.Two-chip type plate spring structure of the invention, structure is simple, firm, operation
Stablize, it is easy to assembly, for existing leaf spring and composite material plate spring, it can either reach and alleviate spring plate weight
The purpose of amount, while solving the problems, such as that one chip leaf spring bearing capacity is insufficient again.
