Abstract
The utility model relates to the technical field of machinery, in particular to a damper provided with a hollow piston rod. The hollow piston rod is arranged in an inner cylinder, a guider assembly and an oil seal are arranged between the hollow piston rod and the inner cylinder, the hollow piston rod is connected with an outer cylinder through a blank cap, and the outer side of the middle part of the outer cylinder is sleeved with a spring plate, and the outer side of one end of the outer cylinder is sleeved with a clamp assembly; the hollow piston rod consists of a client connecting end, a piston end and a hollow pipe, wherein the client connecting end is connected with one end of the hollow pipe, and the other end of the hollow pipe is connected with the piston end. Compared with the prior art, the damper is internally additionally provided with the hollow piston rod and adopts a connecting mode of frictional welding, so that the overall weight of the damper can be lightened under the condition of not reducing the strength.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of vibration damper that is provided with hollow piston rod.
Background technique
Automotive light weight technology is to adopt modern Design and effective means to be optimized design to automobile product, alleviates as far as possible automobile product own wt, to reach the integration objective of loss of weight, consumption reduction, environmental protection, safety.In the component of vibration damper, piston rod is vital part, and not only weight is larger, also bears larger intensity.
Therefore, need to design a kind of can not falling in low intensive situation, the vibration damper that is provided with hollow piston rod of weight reduction.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and providing a kind of can not fall in low intensive situation, the vibration damper that is provided with hollow piston rod of weight reduction.
In order to achieve the above object, the utility model is a kind of vibration damper that is provided with hollow piston rod, it is characterized in that: hollow piston rod is located in inner core, between hollow piston rod and inner core, be provided with guider assembly and oil sealing, between hollow piston rod and urceolus, adopt stifle to be connected, the outside, middle part of urceolus is arranged with spring holder, the outside, one end of urceolus is arranged with clamp assembly, hollow piston rod is comprised of client's connecting end, piston end and hollow tubular, client's connecting end is connected with one end of hollow tubular, and the other end of hollow tubular is connected with piston end.
Between described client's connecting end and described hollow tubular, adopt friction welding.
Between described piston end and described hollow tubular, adopt friction welding.
The utility model compared with the existing technology, has been set up hollow piston rod and has been adopted the Placement of friction welding in vibration damper, makes vibration damper not falling in low intensive situation, alleviate overall weight.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Referring to Fig. 1,1 is hollow piston rod; 2 is stifle; 3 is oil sealing; 4 is guider assembly; 5 is spring holder; 6 is urceolus; 7 is inner core; 8 is clamp assembly.
Embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1, the utility model is a kind of vibration damper that is provided with hollow piston rod.Hollow piston rod 1 is located in inner core 7, between hollow piston rod 1 and inner core 7, be provided with guider assembly 4 and oil sealing 3, between hollow piston rod 1 and urceolus 6, adopt stifle 2 to be connected, the outside, middle part of urceolus 6 is arranged with spring holder 5, the outside, one end of urceolus 6 is arranged with clamp assembly 8, hollow piston rod 1 is comprised of client's connecting end, piston end and hollow tubular, and client's connecting end is connected with one end of hollow tubular, and the other end of hollow tubular is connected with piston end.
In the utility model, in order to increase join strength, between client's connecting end and hollow tubular, adopt friction welding, between piston end and hollow tubular, adopt friction welding.
In the utility model, the solid piston bar structure that the weight ratio of hollow piston rod 1 is traditional has alleviated 20%～30%.
The utility model has been set up hollow piston rod 1 and has been adopted the Placement of friction welding in vibration damper, makes vibration damper not falling in low intensive situation, alleviate overall weight.
