Abstract
The utility model discloses a rotatable damping device of wheelhouse, which is good in damping effect and firm in connection, and comprises a pin shaft. An inner casing is arranged outside the pin shaft, an outer casing is arranged outside the inner casing, a shock pad is arranged between the inner casing and the outer casing, an ear base is arranged on the outer casing, and the end portion of the pin shaft is fixedly connected with a screw bolt. The damping device is applicable to the damping of vehicle wheelhouses.
Description
Technical field
The utility model relates to a kind of shock absorption device, relates in particular to a kind of vehicle cab and chassis bonded assembly shock absorption device of being used for.
Background technology
General rotatable cab adopts bearing pin hinged with being connected of chassis (or car body), owing to there is not shock absorption device, operator's compartment and chassis are rigidly connected by articulated joint, and during machine run, the vibrations on chassis can be directly delivered to operator's compartment, make operation comfort bad.
The utility model content
The rotatable shock absorption device of operator's compartment that technical problem to be solved in the utility model provides a kind of good damping effect, is connected firmly.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises bearing pin, and described bearing pin is provided with inner sleeve outward, and described inner sleeve is provided with outer tube outward, is provided with cushion blocking between described inner sleeve and the outer tube, and described outer tube is provided with the ear seat, captives joint with screw rod in described bearing pin end.
Because the utility model adopts bearing pin that multilayer sleeve and cushion blocking are set outward, transfer of vibration weakens when making machine works, to improve the traveling comfort of operator's compartment, bearing pin adopts screw rod to be connected with multilayer sleeve simultaneously, thereby make operator's compartment more firm with being connected of chassis, and strengthen the rigidity on chassis, improve the stability of machine.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the part partition figure of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the utility model comprises bearing pin 1, and the bearing pin 1 outer inner sleeve 2 that is provided with is provided with outer tube 3 outside the inner sleeve 2, is provided with cushion blocking 4 between inner sleeve 2 and the outer tube 3, captives joint with screw rod 5 in bearing pin 1 end, and outer tube 3 is provided with ear seat 6.
The utility model in use, ear seat 6 is welded on the rear portion of operator's compartment, bearing pin 1 passes inner sleeve 2 again by the hole on the chassis, and pass hole on the chassis by screw rod 5 and be screwed into behind the bearing pin 1 lateral surface compressing inner sleeve 2 two sides and chassis, like this, for the chassis, the utility model is a rigid construction, can strengthen the rigidity on chassis; And for operator's compartment, when machine works, the utility model plays cushioning effect, thereby strengthens the traveling comfort of chaufeur; In the time need keeping in repair to the parts in the chassis, can unload the screw rod of operator's compartment front portion, will turn over behind the operator's compartment.
