Abstract
The utility model provides a dismountable bushing component for an automobile chassis and an assembly structure. The bushing component comprises a bushing colloid, a lining pipe and a fastening backing plate, wherein the bushing colloid is vulcanized outside the lining pipe; a flange is arranged at one end of the bushing colloid; and the diameter of the flange is larger than the diameters of other parts of the bushing colloid. The fastening backing plate is arranged at the flange end of the dismountable bushing component, and is connected with the lining pipe by a fastening bolt and a fastening nut. A raised line is formed on the periphery of the bushing colloid except for the flange end. The two bushing components are matched for use and are pressed into a rod lantern ring from the two ends of the rod lantern ring, so that the bushing components can be taken from the rod lantern ring conveniently in a repairing process. In addition, the bushing component is connected with the fastening bolt which penetrates through the lining pipe by the fastening backing plate at the end part of the bushing component, so that the fastening bolt can be prevented from applying excessive shear pressure on the bushing colloid, and the effect of protecting the bushing colloid, prolonging the service life and improving the reliability of the bushing colloid can be achieved.
Description
Technical field
The utility model relates to the automobile chassis suspension driving system, is specifically related to a kind of bush assembly of car chassis.
Background technology
Increasingly extensive along with the commercial vehicle/comm..vehicle purposes, the user group is more and more higher to the requirement of the performance of commercial vehicle/comm..vehicle and maintenance convenience, and therefore as the rubber bush of consumable accessory in the chassis, the user is also more and more higher for the requirement of its Maintainability And Reliability.The keystone configuration of at present bush assembly employing is with the outer liner tube structure, and as shown in Figure 1, namely lining is comprised of internal lining pipe 1-2, lining colloid 1-1 and outer liner tube 1-3, and three parts by lining colloid 1-1 bonding by Vulcanization together.The interference of bush structure assembly is assembled in the rod member collar of chassis part by outer liner tube 1-3, forms a black box with the rod member collar.Wherein the rod member collar be chassis member with the part of the collar, be to be specifically designed to lining to assemble.
Adopt above structure, when lining colloid cracking damages and after losing efficacy, the bush structure assembly can't take out separately and carry out repair and replacement during maintenance, and need integral replacing rod member assembly from the rod member collar, when causing cost of maintenance and user's service expenditure high.
Therefore, the bush assembly of above structure awaits further to improve.
The utility model content
Deficiency for present prior art existence, the utility model is to propose a kind of detachable bush assembly and mounting structure thereof, its reliability is strong and the life-span is relatively good, effectively solve the bush assembly of car chassis because assembling by interference with the rod member collar, the bush structure assembly can't be dismantled when the damage inefficacy needs maintenance, maintainability is bad, and the problem such as during cost of maintenance.
The technical solution of the utility model is as follows:
The detachable bush assembly of a kind of car chassis comprises lining colloid and internal lining pipe, and the outer sulfuration of described internal lining pipe has the lining colloid, and an end of lining colloid has diameter greater than the flange of remainder.
Further, described bush assembly also comprises fastening backing plate, and described fastening backing plate is arranged on the flange end of detachable bush assembly, is connected with internal lining pipe with clamp nut by binding bolt.Described lining colloid is formed with raised line except the periphery of the remainder of flange end.
The mounting structure of above-mentioned detachable bush assembly, it is to adopt two described detachable bush assemblies to be arranged symmetrically with, flange end is outside, is assemblied in the rod member collar on the automobile chassis parts by interference fit, and flange end is pressed on the both ends of the surface of the rod member collar.
Further, in the flange end of detachable bush assembly fastening backing plate is set respectively, a binding bolt one end and a fastening backing plate welding, the other end passes internal lining pipe and another fastening backing plate of two linings, and is fastening by clamp nut.Described fastening backing plate is used the part of other parts on the vehicle body.
Car chassis of the present utility model can adopt two to be used in conjunction with detachable bush assembly, and the assembling of the rod member collar on chassis is pressed into wherein from the two ends of the rod member collar, bush assembly is removed from the rod member collar during convenient for maintaining like this.In addition; bush assembly is connected with the binding bolt that passes internal lining pipe by the fastening backing plate of end; since around the internal lining pipe with lining colloid bonding by Vulcanization together; therefore in the future fully absorption and the mitigation in the lining colloid of force and moment of Self-fastening bolt of internal lining pipe; alleviate pressure and the shearing force of bearing on the lining colloid unit area; prevent that binding bolt from directly forming excessive shear pressure to the lining colloid, reach the effect of protecting the lining colloid and improving its life and reliability.
As seen, adopt the utility model structure, when the lining colloid in the chassis part occurs such as inefficacies such as cracking, wearing and tearing, only need pull down fastening backing plate and binding bolt, the repair and replacement bush assembly gets final product, and is easy to maintenance quick, and expense is cheap.
Description of drawings
Fig. 1 is the structural representation of common non-dismounting type bush assembly;
Fig. 2 is the structural representation of the detachable bush assembly of the utility model;
Fig. 3 is the assembling section of the detachable bush assembly of the utility model.
Among the figure: 1,Bush assembly, 1-1 lining colloid, 1-2 be by internal lining pipe, the 1-3 outer liner tube, and the 1-1-1 flange, the 2 rod member collars,, 3 fastening backing plates, 4 binding bolts.
The specific embodiment
With reference to Fig. 2 and Fig. 3, existing formation to the detachable bush assembly of the utility model further specifies.
The detachable bush assembly of the utility model as shown in Figure 2, it is formed by lining colloid 1-1 and internal lining pipe 1-2 sulfuration, forms one, two combinations are used in conjunction with.One end of every lining colloid has diameter greater than the flange 1-1-1 of remainder, and the periphery of all the other column parts of lining colloid has raised line, to increase the interference fit power of lining colloid and the rod member collar.
Shown in Fig. 3 assembly drowing, when the rod member collar 2 of the detachable bush assembly of the utility model and chassis part assembles, with the flange end of two bush assemblies outwardly, two ends from the rod member collar are pressed into symmetrically, with rod member collar interference fit, form the suitable magnitude of interference and keep certain dismounting power, and prevent that lining colloid play in the collar of rod member from producing shock and vibration.
Be fitted into the rod member collar of chassis part at bush assembly after, outboard flanges end at two bush assemblies can be used existing part on the vehicle body with fastening backing plate 3() with the torsion tightening compacting with bush assembly of binding bolt 4 and matching nut, prevent the loosening abnormal sound of lining.Specifically, with fastening backing plate 3 welding of binding bolt 4 one ends and an end, the other end passes the internal lining pipe 1-2 of two linings and the fastening backing plate 3 of the other end, and is then fastening by clamp nut.
Adopt above structure, when the lining colloid of part occurs such as inefficacies such as cracking, wearing and tearing, only need to change bush assembly and get final product.After being about to fastening backing plate and binding bolt and removing, bush assembly is taken out, change brand-new bush assembly after, will fastening backing plate with the binding bolt assembling after get final product, easy to maintenance fast, and expense is cheap.
