Abstract
The utility model discloses a four-connecting rod vibration absorption front fork arranged at a bicycle. A longitudinal beam which is a main part is processed into a flat box or groove shape part; a tube bushing is a horizontal beam fixed at two sides of the utility model; a connecting part, another main part of the utility model, acts as a tube part. The arrangement can effectively lower gravity of a structure part and reduce manufacture cost.
Description
Technical field:
The utility model relates to a kind of front suspension fork of bicycle, especially four link type shock-absorbing front forks.
Background technology:
The bicycle front fork damping of existing a kind of public use, it has two longerons up and down, longeron two ends fixed cross beam, there are four connecting rods hinged with the crossbeam two ends respectively, constitute the tetragonal body framework of two dimensional motion, see by the side and to be four-bar linkage structure, bicycle profile tube is fixed therein on the crossbeam, front fork is fixed on the longeron relative with this crossbeam, shock-damping device (can be cylinder, hydraulic actuating cylinder or brute spring, mould rubber etc. a firmly) end and front fork are hinged, the rod hinge connection that the other end is relative with above-mentioned crossbeam.The damping performance of this mechanism is better, its longeron, crossbeam all are metal rods, by block of metal adopt car, mill, conventional meanses such as boring, mill process, cost is higher, and member is a solid member, and weight is bigger, also can adopt light-weight metal to process with casting, forging mode, but strength variance is difficult to satisfy operating needs.Simultaneously, from the angle of strength of material, during member stress, its stress is mainly born by the outer layer segment of its cross-sectional plane, and the stress that its heart portion bears is few, and prior art adopts solid component to cause the waste of material in fact.
The utility model content:
The purpose of this utility model is: a kind of potentiality that make full use of material are provided, and can effectively alleviate construction weight, the four-bar suspension fork of bicycle that cuts down finished cost.
Four-bar suspension fork of bicycle described in the utility model, it has two longerons 1 up and down, longeron 1 two ends fixed cross beam 2, there are four connecting rods 4 hinged with crossbeam 2 two ends respectively, constitute the tetragonal body framework of two dimensional motion, see by the side and to be four-bar linkage structure, bicycle profile tube 5 is fixed therein on the crossbeam 2, front fork is fixed on the longeron 1 relative with this crossbeam 2, shock-damping device 7 (can be cylinder, hydraulic actuating cylinder or brute spring, mould rubber etc. firmly) end and front fork 6 be hinged, the connecting rod 4 that the other end and above-mentioned crossbeam 2 are relative is hinged, and it is characterized in that: described longeron is flat box or groove shape spare, and the crossbeam that is fixed on its two ends is a tubular sleeve; Described connecting rod is a tube-like piece, and two ends radially are fixed with annular shaft bearing or axle sleeve.
Because longeron of the present utility model, crossbeam and connecting rod have all adopted the hollow unit of box-like or tubulose, make its weight alleviate greatly, and box-like or groove shape member can be formed by plate stamping, raw material is easy to get, low processing cost, tube-like piece can directly be formed by the tubing cutting, and cost is lower, and longeron, crossbeam can be integrally welded.Described hollow unit has utilized the mechanical property of material to a greater degree, thereby has saved material.
Description of drawings:
Fig. 1 is a scheme drawing of the present utility model
The specific embodiment:
As shown in Figure 1, it has two longerons 1 up and down, longeron 1 two ends fixed cross beam 2, there are four connecting rods 4 hinged with crossbeam 2 two ends respectively, constitute the tetragonal body framework of two dimensional motion, see by the side to be four-bar linkage structure, bicycle profile tube 5 is fixed therein on the crossbeam 2, front fork is fixed on the longeron 1 relative with this crossbeam 2, and shock-damping device 7 (can be cylinder, hydraulic actuating cylinder or brute spring, mould rubber etc. a firmly) end and front fork 6 are hinged, and the connecting rod 4 that the other end and above-mentioned crossbeam 2 are relative is hinged.Described longeron is flat box or groove shape spare, and the crossbeam that is fixed on its two ends is a tubular sleeve; Described connecting rod is a tube-like piece, and two ends radially are fixed with annular shaft bearing or axle sleeve.
Described longeron, crossbeam can be fixed by welding manner.
