Abstract
A kind of bush Assembly, it comprises a housing (50), one is positioned at the link (56) of housing (50) and at least one is positioned at resilient bushing (54,55) between housing (50) and the link (56).Lining (54,55) is included in the housing (50) fully.A surface of lining (54,55) is an arcuate surface, also has a surface to adapt for arcuate surface and with the arcuate surface of lining (54,55) on housing (50) or link (56).
Description
The present invention relates to a kind of novel bush Assembly that is used on the likes such as torsion bar, rear stabilizer or steering arm.
The conventional construction that is suitable for the bush Assembly of such use is generally steel bushing by a ferrule element one and a rubber bushing is formed.The internal surface bonding of rubber bushing and ferrule element also has link or the mandrel (being generally metalwork) and rubber bushing resilient engagement with sphere or cylindrical lip part usually.Ferrule element is pressed in the earhole of each end of torsion bar by large-scale press usually, makes it to realize interference fit with the earhole internal surface.
The conventional bushings assembly that is used on the equalizer bar has similar structure, and its lining has a metal-coating tube, the respective surfaces press fit of the earhole of this outer sleeve and each end of equalizer bar.Internal surface at the metal-coating tube also is bonded with a rubber bushing.
This traditional bush Assembly is when repairing with maintenance, its cost is high, usually method therefor is that torsion bar or equalizer bar are pulled down from the chassis, and bar or beams that these are quite heavy are transported on the special pressure machine, and the rubber bushing of the bonding respective end from bar or beam is extruded.Usually, former lining is scrapped, and need to change a new lining, and new lining also need be pressed into by the weight of press machine in the earhole that matches of each respective end of bar or beam, sends bar or beam back to repair shop then it is reinstalled on the chassis.Do not possess long working life if sticking rubber ftractures under the repeated deformation condition because of it or ruptures, then the replacing of this conventional bushings and maintenance problem are just more serious.
21, No. 969/88 Australian patent specification discloses a kind of improved bush Assembly, and a housing is wherein arranged, and a through hole is arranged on this housing, and the lining that one or more elastic materials are made is housed in the through hole, and a bar or rod pass in lining.Be shaped on the part of positioning element on bar or the rod, thus lining be limited to certain position as bar or rod.The outer surface of lining is taper, the one interior wide face that adapts with the lining male cone (strobilus masculinus) is arranged on the housing, the resilient bushing of this bush Assembly is not to be bonded on the housing, therefore convenient disassembly when changing the wearing and tearing lining, but the parts such as the steering arm that are connected by this bush Assembly and the amount that is installed in relative movement required between the double-screw bolt in the bush Assembly can't reach desirable requirement.
4,007, No. 924 US Patent specification discloses a kind of elastic support, and this bearing is at an external member and place between the inner member in it, and the internal surface of external member and the outer surface of inner member generally are turning surface.In illustrated embodiment, have at least two coaxial metal stiffening rings to be used to strengthen bearing at two of elastic support relative axle heads, stiffening ring or embed in the bearing or be fixed on the outer surface of bearing has at least a bearing axle head to stretch out adjacent with it external member end.
This seat structure complexity.And need to strengthen its axial end portion.
The object of the present invention is to provide a kind of improved bush Assembly, this assembly can reduce above-mentioned drawback at least.
For this purpose, the invention provides a kind of bush Assembly, it comprises a housing, one in housing link and at least onely place between housing and the link and be limited to resilient bushing within the housing fully, one surface of resilient bushing is an arc, and an arc shaped surface that matches with this arcuate surface is also arranged on housing or the link.
Lining is the whole lining that can be made by elastic material, also can be the lining that two independent elastic materials are made.In addition, lining can also be combined by one or two resilient bushing and a metal ring.Elastic material can be rubber or polyurethane.
Housing can be a cylindricality substantially, and it preferably can limit the position of lining.Can have a defining flange on the housing, this flange can be annular, and is positioned at an end place that is adjacent to housing, or the annular groove that can be made on housing or the link is used for the placement positioning part, and locating piece can be a snap ring, between annular groove and flange certain intervals is arranged.In addition, annular groove also can be arranged on the link.
Oil leab preferably passes housing and lining, and the oil duct on the housing can be made up of the one or more warp-wises hole on an annular groove and the housing.Described hole can penetration liner, or leaves a gap between adjacent lining.
Link can be a tubulose, and as other embodiments, link is solid cylinder substantially.If it is the link end is shaped on the attachment portion, then even more ideal.
Below with reference to accompanying drawing embodiments of the invention are described.
