Description

Bull-dozer engine shock absorber

Technical Field

The utility model relates to a bumper shock absorber technical field, in particular to bull-dozer engine shock absorber.

Background

The shock absorber is a device which is widely applied in the mechanical industry and used for reducing the vibration amplitude of an engine body, and particularly in the field of engineering machinery with complex working conditions and severe environment, the shock absorber is basically a standard configuration for reducing the vibration of an engine, a transmission part and a cab, so that the shock absorber is more and more emphasized in recent years, and the related NVH industry also more and more arouses the attention research of the industry. Among various shock absorbers, the shock absorber of the engine has the most prominent effect, and the quality of the shock absorber determines the service life of the engine, the noise of the whole engine, the vibration of related transmission parts and the like, so the structural design of the shock absorber becomes more important.

The shock absorption of the engine of the bulldozer at the present stage is generally divided into a shock absorber in the vertical direction and a shock absorber in the horizontal direction according to the shock absorption and stress direction. The vertical direction bumper shock absorber is also simple to the shock attenuation effect preferred of engine, but owing to in the installation screw up process, thereby the shock attenuation piece takes place to warp the skew easily and leads to the engine center to be connected the poor problem of centering nature with the driving medium, so should not use in the occasion that engine and driving medium have the concentricity requirement.

At present, the shock absorbers of the engine of the engineering machinery such as a bulldozer and the like mainly adopt the horizontal shock absorber, and the traditional support is of a shaft structure, and the base is of a hole structure, so that the shock absorbers have many defects; secondly, the cost is high, and the cost of the shock absorber is high due to the complex structure and many parts, so that the large-scale application of the shock absorber is limited; finally, the manufacturing error is large, and as the damping rubber blocks need to be installed in pairs, the accuracy of the installation parts is higher, and the problem that the installation is not in place due to machining errors is easily caused in the manufacturing process.

SUMMERY OF THE UTILITY MODEL

The utility model provides a bulldozer engine horizontal direction bumper shock absorber structure is complicated among the correlation technique, with high costs, the big problem of manufacturing error, provides a bulldozer engine bumper shock absorber, adopts less spare part when having better shock attenuation effect, simple structure and reduce cost reduce manufacturing error's production moreover.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme: a bulldozer engine shock absorber, comprising:

the support is arranged on the engine body, and an inner hole is formed in the support;

the damping block is arranged in an inner hole of the support and is positioned through the axial end face of the inner hole of the support, and the damping block is provided with an inner hole;

the shaft part of the base is arranged in an inner hole of the damping block and is positioned by contacting the axial end surface of the base with the outer end surface of the damping block; the other end of the base is arranged on a rack of the bulldozer.

Preferably, the support is installed on the engine body through a positioning pin and is fastened through a bolt I.

Preferably, the damping block consists of damping rubber, a damping outer ring and a damping inner ring.

Preferably, the base is fixed on the frame through a bolt II.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model changes the shaft structure of the traditional support into the structure of a hole, changes the hole structure of the traditional base into the shaft structure, changes the damping block from two groups of installation into a group of damping block installation, installs the support on the engine body, installs the damping block in the shaft hole of the support, and finally inserts the shaft part of the base into the inner hole of the damping block, thus having simple structure, simplifying the complicated steps of installation and greatly improving the assembly efficiency; compared with the traditional shock absorber, the shock absorber has fewer parts, can greatly reduce the manufacturing cost after being processed by selecting proper materials, can also improve the utilization rate of processing materials, and still has better shock absorption effect; the utility model discloses spare part simple structure behind well spare part optimal design needs the finish machined face less, and the production of reducible manufacturing error reduces the spare part processing degree of difficulty and the inspection degree of difficulty.
