Connecting structure of bulldozer pivot and bogie frame as well as bulldozer

Abstract

The invention discloses a connecting structure of a bulldozer pivot and a bogie frame as well as a bulldozer, belonging to the field of a bulldozer assembly. The connecting structure comprises a pivot 1, a bottom plate 2 and a pivot cylinder 3, wherein one end of the pivot 1 stretches into the pivot cylinder 3; one end of the pivot, which stretches into the pivot cylinder 3, is connected with the bottom plate 2 in the pivot cylinder 3; the pivot cylinder 3 is internally provided with an annular bulge for limiting the bottom plate 2 to move along the direction of the pivot 1; a disc-shaped spring is arranged between the bottom plate 2 and the annular bulge of the pivot cylinder 3; the disc-shaped spring is sleeved on the pivot 1; the shape of an outer ring of the disc-shaped spring is matched with the inner shape of the pivot cylinder 3; and the shape of the disc-shaped spring is matched with the shape of the pivot 1. The technical scheme has the beneficial effects that a buffering manner of the disc-shaped spring is utilized so that the abrasion of repeated movement is avoided and a better buffering performance is provided; and the disc-shaped springs with different characteristic curves are adopted and the same disc-shaped spring adopts different combination manners, so that the size of a buffering force and the compression deformation amount are changed to adapt to different types and working conditions.

Description

technical field [0001] The invention relates to a bulldozer assembly, in particular to a connection structure between a bulldozer pivot and a trolley frame and the bulldozer. . Background technique [0002] The existing high-drive crawler bulldozer pivots are generally connected to the frame by being connected to the frame, the pivots are sleeved in the pivot cylinder and fixedly connected to the bottom plate by bolts. When the bulldozer is working, the chassis frame will have a relative displacement in the axial direction of the pivot shaft, which will impact the connection structure between the pivot shaft and the chassis frame, causing premature damage to the connection structure and bringing potential safety hazards. Contents of the invention [0003] In view of the above-mentioned problems existing in the connection structure between the bulldozer pivot and the trolley frame, a connection structure between the bulldozer pivot and the trolley frame and the bulldozer....
