Abstract

The utility model discloses an auxiliary vehicle frame bushing block, which comprises an inner pipe, wherein concave cavities are arranged on the two symmetrical side walls of the inner pipe, the outside of the inner pipe is sheathed with a vulcanization vibration reduction body, the vulcanization vibration reduction body comprises a vulcanization rubber body and an outer pipe, the outer pipe consists of two mutually matched half outer pipe bodies and is in a half opening structure, in addition, the half outer pipe bodies are embedded and arranged in the vulcanization rubber body, the pipe walls of the half outer pipe bodies are inwards stamped to form recessed structures, and the recessed structures correspond to the positions of the concave cavities. The auxiliary vehicle frame bushing block has the advantages that the outer pipe is in the half opening structure, so the recessed degree can be designed according to the axial rigidity during the inward stamping on the half outer pipe bodies, and in addition, the half outer pipe bodies cannot deform during the inward stamping. In addition, the processing of the recessed structures can also be easy through the outer pipe in the half opening structure, and the processing cost is effectively reduced.

Description

A kind of subframe lining
Technical field
The utility model relates to a kind of vehicle link, especially relates to a kind of subframe lining.
Background technique
The appearance of subframe assembly is the again innovation of Automobile Design, it has improved travelling comfort and the suspension stiffness of chassis system, and the subframe lining is as the tie point of subframe assembly and vehicle body, it has larger impact to body vibrations, car room noise level, the quality of subframe bushing design will directly have influence on the vibration noise level of car load, be the key factor that affects riding comfort.
At present, a kind of subframe lining that occurs on the market comprises inner tube, outer tube and vibration isolation rubber layer, and the vibration isolation rubber layer vulcanizes outside inner tube, and outer tube is embedded in the vibration isolation rubber layer, and the inside punching press in the symmetrical two side of outer tube forms sunk structure.This subframe bush structure is simple, but and pass through the inside punching press Effective Raise of outer tube axial rigidity, but because outer tube is the circular pipe of an integral body, therefore the processes to the inside punching press of outer tube is comparatively difficult, and outer tube can be out of shape when higher to the degree of the inside punching press of outer tube, thereby causes this subframe lining to use, and if when inwardly the degree of the low i.e. depression of the degree of punching press is low, then the lifting of axial rigidity is limited, can't satisfy high axial rigidity requirement.
Summary of the invention
It is high that technical problem to be solved in the utility model provides a kind of axial rigidity, and the subframe lining of easy processing and fabricating.
The utility model solves the problems of the technologies described above the technological scheme that adopts: a kind of subframe lining, comprise inner tube, it is characterized in that being provided with cavity on the symmetrical two side of described inner tube, described inner tube is socketed with the sulfuration damping body outward, described sulfuration damping body comprises the vulcanized rubber body and the outer tube of double opening structure being comprised of two half outer tube bodies that cooperatively interact, and described half outer tube body is embedded in the described vulcanized rubber body, the inside punching press of the tube wall of described half outer tube body is sunk structure, and described sunk structure is corresponding with the position of described cavity.
It is sphere and at the bottom of the chamber of described cavity in the middle of the described sunk structure.
The chamber wall of described cavity is the inclined-plane, and vertical both sides of described sunk structure are the arc-shaped transition section, and described arc-shaped transition section is corresponding with the position of the chamber wall of described cavity.
The making material that described inner tube and described outer tube adopt is aluminium.
Compared with prior art, the utility model has the advantage of: by a sulfuration of socket damping body outside inner tube, and this sulfuration damping body comprises the vulcanized rubber body and the outer tube of double opening structure being comprised of two half outer tube bodies that cooperatively interact, half outer tube body is embedded in the vulcanized rubber body, the inside punching press of the tube wall of half outer tube body forms a sunk structure, because outer tube is to half-open structure, therefore when double inside punching press of outer tube body, can require according to axial rigidity the degree of design depression, and inwardly during punching press half outer tube body can not be out of shape; In addition, the outer tube of double opening structure is also so that the easier processing of sunk structure effectively reduces processing cost.
Description of drawings
Fig. 1 is the perspective view of subframe lining of the present utility model;
Fig. 2 is the cross-sectional schematic of subframe lining of the present utility model.
Embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
A kind of subframe lining that the utility model proposes, as shown in the figure, it comprises inner tube 1, be provided with cavity 2 on the symmetrical two side of inner tube 1, the outer sulfuration damping body 3 that is socketed with of inner tube 1, sulfuration damping body 3 comprise vulcanized rubber body 5 and the outer tube of double opening structure being comprised of two half outer tube bodies 4 that cooperatively interact, and half outer tube body 4 is embedded in the vulcanized rubber body 5, the inside punching press of the tube wall of half outer tube body 4 is sunk structure 6, and sunk structure 6 is corresponding with the position of cavity 2.
In this specific embodiment, 61 is sphere and at the bottom of the chamber of cavity 2 21 in the middle of the sunk structure 6, the chamber wall 22 of cavity 2 is the inclined-plane, vertical both sides of sunk structure 6 are arc-shaped transition section 62, arc-shaped transition section 62 is corresponding with the position of the chamber wall 22 of cavity 2, be that rubber body between sunk structure 6 and the cavity 2 is when thinner when the perpendicular distance between the chamber wall 22 of the perpendicular distance between 21 in the middle of the sunk structure 6 and at the bottom of the chamber of cavity 2 and arc-shaped transition section 62 and cavity 2 is shorter, axial rigidity and radial rigidity are just larger, therefore be not to make the rubber body between sunk structure 6 and the cavity 2 get over Bao Yuehao in the preparation, but require suitably to design the sinking degree of sunk structure 6 according to axial rigidity.
At this, inner tube 1 and outer tube all adopt aluminium to make.
