Abstract
The utility model discloses a rocker arm assembly applied to a gearbox of a motor vehicle. The rocker arm assembly comprises a rocker arm body (1) and a positioning column (2), wherein a balance weight (3) with a hollow structure is arranged at one end of the rocker arm body (1) through screws (4); and a rubber vulcanization mat (7) is arranged between the screws (4) and the balance weight (3). According to the rocker arm assembly disclosed by the utility model, due to the adoption of the matching of the balance weight with the hollow structure with the screws, a favorable balance action can be achieved according to the requirements of gear shifting and reversing operations, the balance performance of the rocker arm assembly is increased and further the gear shift and the gear reverse are more flexible and free. The rubber vulcanization mat plays a role of buffering the collision and friction between the screws and the balance weight, so that the wear is reduced, the wear resistance is improved, the damping effect is achieved and further the service life of the rocker arm assembly is prolonged.
Description
Technical field
The utility model relates to a kind of motor vehicle gearbox field, specifically relates to the Rocker arm assembly that a kind of motor vehicle gearbox is used.
Background technique
At present, the balancing weight of the Rocker arm assembly of motor vehicle gearbox application has certain balanced action, and it belongs to solid construction for rigid material, can wholely move and make its balance, the degree of balance not really desirable during use, has influenced the service behaviour of Rocker arm assembly; And collision between the part and friction, big lossy the working life of Rocker arm assembly.
Summary of the invention
To the deficiency that existing technology exists, the purpose of the utility model is to provide a kind of balance, the good few Rocker arm assembly of loss of the degree of balance.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of Rocker arm assembly; Comprise rocker body, locating column, through screw the balancing weight with hollow-core construction is housed at an end of said rocker body, and is equipped with vulcanization of rubber pad between this screw and the balancing weight.
Through adopting technique scheme, the balancing weight with hollow-core construction can play good balanced action according to gear shift, the reverse gear action need of Rocker arm assembly with cooperating of screw, has increased the balance quality of Rocker arm assembly, makes gear shift, reverse gear more nimbly and freely.Vulcanization of rubber pad has then played collision and the effect of friction between buffer screw and the balancing weight, has reduced wearing and tearing, has increased wear resistance, reaches damping effect, has obtained prolongation in working life of Rocker arm assembly thereby make.
Description of drawings
Fig. 1 is the structural representation of the utility model Rocker arm assembly.
Fig. 2 is the left-hand side view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and mode of execution the utility model is done further to describe explanation.
Referring to Fig. 1, Fig. 2; The utility model is applied to the Rocker arm assembly of motor vehicle gearbox; Comprise rocker body 1 (containing connecting plate and connecting base), locating column 2 (sphere); Through screw 4 balancing weight 3 with hollow-core construction (be an end load joint chair, its other end assembling pouring weight of connecting plate, and balancing weight and connecting base be in the homonymy of connecting plate, locating column then is in the opposite side of connecting plate) is housed at an end of said rocker body 1; And be equipped with vulcanization of rubber pad 7 (its material is a natural rubber, has cushioning effect) between this screw 4 and the balancing weight 3.Promptly the part of this screw 4 is contained in the balancing weight, its another part exposes outside balancing weight and be contained on the end of rocker body.
In the outer end of said screw 4 and on rocker body 1 (its connecting plate), packing ring 5 and nut 6 are housed, be used for fixing screw 4.
Claims (2)
