Abstract
The utility model relates to a link lever and a positioning sleeve; the utility model mainly comprises a link lever and a positioning sleeve; the link lever is divided into the front section of the link lever and the back section of the link lever; the front section of the link lever and the positioning sleeve form an integral screw rod and the screw rod is fixed and connected with the back section of the link lever. The screw rod and the back section of the link lever are fixed through the process of friction welding. The utility model has the beneficial effect: 1. the screw rod can be purchased according to the standard part and the cost is greatly reduced; 2. the positioning sleeve can be formed by compression and the size precision can be ensured; 3. the screw rod is convenient for surface treatment as a single piece and the problem of corrosion can be solved; 4. the processing procedures of the link lever are greatly reduced, the necessary raw material is reduced and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of automobile vibration damper accessory, especially a kind of connecting rod and setting sleeve structure.
Background technique
For the vibration damper of independent suspension, what have in the upper end of damper link is equipped with setting sleeve, and accompanying drawing 1 is a kind of of common structure, this structure is more commonly used aborning, adopting connecting rod and setting sleeve is the transition fit form, i.e. after the connecting rod integral processing, setting sleeve is pressed onto on the connecting rod again.Its advantage is that the processing technology of connecting rod is ripe, but the defective of this structure is: 1, setting sleeve need carry out the single-piece cutting, and manufacturing efficiency is low; 2, the Machining of Connecting Rod operation is many, the cost of production height; 3, the above length L 1 of setting sleeve is about about 1/4 of connecting rod length overall, and diameter of phi 2 is about 50～62% of connecting rod diameter of phi 1, so material is relatively wasted; 4, outer diameter D 1 required precision of setting sleeve is higher, and processing is difficult for guaranteeing; 5, the elasticity that cooperates with connecting rod of setting sleeve is wayward, and tension then press-fits difficulty; Cross pine then setting sleeve easily come off from connecting rod; 6, the above shaft portion of setting sleeve is difficult for carrying out surface treatment because of equipment, technology etc., can only be coated with rust preventive oil before packing, but of long duration is prone to corrosion phenomena, and therefore the client complains.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of connecting rod and setting sleeve structure are provided.
The utility model solves the technological scheme that its technical problem adopts: this connecting rod and setting sleeve structure, mainly comprise connecting rod and setting sleeve, described connecting rod is divided into connecting rod leading portion and connecting rod back segment, and connecting rod leading portion and setting sleeve constitute the screw rod of integrative-structure, and screw rod is fixedlyed connected with the connecting rod back segment.
Described screw rod is fixedlyed connected by friction welding with the connecting rod back segment.
The effect that the utility model is useful is: 1, screw rod can directly be purchased by standard piece, and cost reduces greatly; 2, the setting sleeve part can be by the upsetting pressure moulding, and dimensional accuracy is guaranteed; 3, screw rod is convenient to carry out surface treatment as single-piece, and the corrosion problem is solved; 4, the manufacturing procedure of connecting rod reduces, and raw material reduce, and cost of production reduces.
Description of drawings
Fig. 1 is the main TV structure schematic representation of common structure;
Fig. 2 is a main TV structure schematic representation of the present utility model;
Fig. 3 is an assembling exemplary construction schematic representation of the present utility model;
Description of reference numerals: connecting rod 1, setting sleeve 2, friction welding 3, screw rod 4, vibration damper 5, buffer 6.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 2, this connecting rod and setting sleeve structure, mainly comprise connecting rod 1 and setting sleeve 2, described connecting rod 1 is divided into connecting rod leading portion and connecting rod back segment, connecting rod leading portion and setting sleeve 2 constitute the screw rod 4 of integrative-structure, screw rod 4 is fixedlyed connected by friction welding 3 with the connecting rod back segment, and screw rod can directly be purchased by standard piece.
The architecture advances of this practical connecting rod and setting sleeve promptly designs at above-mentioned defective, this structure mainly from reduce operation, reduce cost, the angle of anti-corrosion considers, to go up end link and setting sleeve and be screw rod, get final product with the connecting rod welding then, overcome the shortcoming of common structure as an integral body.
The improved place of the needs of this structure is: 1, friction welding technological is not very ripe; 2, screw rod external diameter Φ 2 is difficult for guaranteeing with the coaxality of connecting rod external diameter Φ 1.
As shown in Figure 3, connecting rod 1 is installed in the structural drawing on the vibration damper 5, and connecting rod 1 is provided with buffer 6.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
Claims (2)
