Abstract
The utility model discloses the connection structure of a kind of swing arm sleeve pipe and swing arm sleeve pipe and bush of swing arm, swing arm sleeve body is circular ring structure, its sidewall offers axially through opening, the internal diameter of this circular ring structure is less than the external diameter of the bush of swing arm be mated, described swing arm sleeve body has outward extending flange respectively in the both sides of opening part, and the outside of one of them flange is welded with project-welding nut, another flange offers bolt through-hole in the position corresponding with this project-welding nut.The utility model both ensure that to have enough withdrawal forces between sleeve pipe and lining, in turn ensure that central siphon reliable durable.
Description
Technical field
The utility model belongs to auto parts and components, is specifically related to the connection structure of a kind of swing arm sleeve pipe and swing arm sleeve pipe and bush of swing arm.
Background technology
Swing arm sleeve pipe in vehicle structure is mainly used in press-fiting bush of swing arm, and bush of swing arm, as the important spare part of car load comfort property, can filter the small vibrations raising car load traveling comfort that road surface is delivered to vehicle body.Current central siphon mostly is straight-tube shape, solid drawn pipe turnery processing is adopted to be made, during local welding, distortion is large, in turn inside diameter process, likely because the withdrawal force between sleeve pipe and lining produces displacement not, cause automobile in the process of moving, when particularly turning, easily produce abnormal sound, also can affect the service life of lining, thus affect traffic safety.
The swing arm sleeve pipe that partial automobile have employed common opening solves the inadequate problem of lining withdrawal force, a kind of swing arm sleeve pipe with opening disclosed in CN 201941540 U, as depicted in figs. 1 and 2, it has the body 1 by sheet stamping forming, and body axial limit, two ends joint has flexible opening 2.The axially open 2 that this patent is left by body 1 wall avoids welding deformation.In order to realize having larger withdrawal force between sleeve pipe and lining, needing to leave enough magnitudes of interference to lining 3, causing when press-fiting, sleeve pipe produces moderate finite deformation.And this position is when running car, stressed comparatively large owing to working, use a period of time rear sleeve easily to produce plastic deformation, cause withdrawal force decay and produce displacement.Therefore, the connection structure developing a kind of new swing arm sleeve pipe and swing arm sleeve pipe and bush of swing arm is necessary.
Summary of the invention
The purpose of this utility model is to provide the connection structure of a kind of swing arm sleeve pipe and swing arm sleeve pipe and bush of swing arm, can guarantee to have enough withdrawal forces between sleeve pipe and lining, can ensure sleeve pipe reliable durable again.
Swing arm sleeve pipe described in the utility model, swing arm sleeve body is circular ring structure, its sidewall offers axially through opening, the internal diameter of this circular ring structure is less than the external diameter of the bush of swing arm be mated, described swing arm sleeve body has outward extending flange respectively in the both sides of opening part, and the outside of one of them flange is welded with project-welding nut, another flange offers bolt through-hole in the position corresponding with this project-welding nut.
The connection structure of swing arm sleeve pipe described in the utility model and bush of swing arm, comprise bush of swing arm and swing arm sleeve pipe, this swing arm sleeve body is circular ring structure, its sidewall offers axially through opening, described bush of swing arm is arranged in this circular ring structure, and the internal diameter of circular ring structure is less than the external diameter of bush of swing arm, also comprise bolt, described swing arm sleeve body has outward extending flange respectively in the both sides of opening part, and the outside of one of them flange is welded with project-welding nut, another flange offers bolt through-hole in the position corresponding with this project-welding nut, described bolt coordinates together with two gib through bolt through-hole and project-welding nut.
The utility model has the following advantages: the sidewall of swing arm sleeve body is provided with axially through opening, local welding can be avoided to be out of shape by this opening; Internal diameter due to circular ring structure is less than the external diameter of the bush of swing arm be mated, and makes to have enough magnitudes of interference between swing arm sleeve pipe and bush of swing arm, thus solves bush of swing arm pressing-in force and the inadequate problem of withdrawal force; After bush of swing arm presses fit into swing arm sleeve pipe, then by flange bolt, swing arm sleeve pipe is locked, ensure that the withdrawal force of bush of swing arm is unattenuated, make sleeve pipe work reliably durable.
