Description

Rear-swing arm lining

Technical field

The utility model belongs to machine parts technical field, relates to a kind of lining, particularly a kind of rear-swing arm lining.

Background technology

Along with the develop rapidly of society, automobile as one easily the vehicle in people's daily life, become very universal, but people bring easily simultaneously at enjoyment automobile, there has also been very high requirement to the comfort property of automobile.Bush of swing arm of automobile is as the important spare part of car load comfort property, and it can filter the comfort property that the road surface small vibrations be delivered on vehicle body improve car load.Existing bush of swing arm is formed by cylindrical metal purchasing ore, cylindrical shape rubber layer and the sulfuration of cylindrical metal inner frame, due to the metal interior skeleton of cylinder type and cylindrical shape rubber layer sulfuration area little, in Suspension movement process, be easy to rubber to tear, reduce the service life of lining; In addition cylindrical shape inner frame relatively with cylindrical shape rubber layer up and down, sway is out of shape time ratio and is easier to, the axis of lining and radial rigidity are difficult to control in scope of design.

A kind of bush of swing arm of automobile (application number: 201120070788.5) disclosed in Chinese patent literature, reinforcing sleeve is simple shape structure and the edge that has bent outward to roll over, one end, rubber is wrapped with in reinforcing sleeve, reinforcing sleeve and rubber form columnar structured, before swing arm, inner covering is arranged within this cylindrical shape, and before swing arm, this cylinder is longer than at the two ends of inner covering; Before swing arm, liner jacket wall has elastic groove penetrating inside and outside two, two elastic grooves be symmetrically set and through to reinforcing sleeve along the one end at place.But this bush of swing arm only arranges elastic groove to absorb radial pressure, therefore the ability of its carrying radial stress is poor.

Summary of the invention

The purpose of this utility model there are the problems referred to above for existing technology, proposes a kind of rear-swing arm lining that can carry radial stress preferably.

The purpose of this utility model realizes by following technical proposal: rear-swing arm lining, comprise inner core and be sheathed on the urceolus in outside of described inner core, it is characterized in that, the spring that some radial directions along described urceolus are arranged is provided with between described inner core and described urceolus, described spring is evenly arranged centered by the axis of described inner core, the sidewall of described urceolus is equipped with registration mast and described registration mast and described spring one_to_one corresponding, described registration mast is provided with convex shoulder, one end of described spring is resisted against on the lateral wall of described inner core, the other end of described spring is resisted against on described convex shoulder, elastic rubbery body is injected with in the cavity formed between the lateral wall of described inner core and the madial wall of described urceolus.

Urceolus is connected with base in use, and inner core is connected with swing arm.When inner core is subject to less diametral load, elastic rubbery body generation deformation, when inner core is subject to larger diametral load, there is deformation in spring and elastic caoutchouc simultaneously, makes this rear-swing arm lining have the ability of carrying radial stress preferably.By arranging through the registration mast of outer tube side wall, the other end of spring is resisted against on the convex shoulder of registration mast, has the easy to connect and good advantage of locating effect.

In the above-mentioned latter in bush of swing arm, the outside of described inner core is provided with detent, and one end of described spring is embedded in described detent.One end of spring is embedded in detent, has location failure-free advantage.

In the above-mentioned latter in bush of swing arm, the lateral wall undulate of described inner core, described detent is positioned on trough.The lateral wall undulate of inner core, is convenient to the connection making inner core and elastic rubbery body, has location failure-free advantage.

In the above-mentioned latter in bush of swing arm, described spring is all in compressive state.When then radial forces, predetermincd tension and the radial forces of corresponding spring offset, and have and carry radial forces preferably, improve the load-carrying capacity of this rear-swing arm lining.

In the above-mentioned latter in bush of swing arm, described inner core is parallel on axial the same side and is equipped with two-layer spring set up and down, the same side of the madial wall of described urceolus is provided with the registration mast of two-layer correspondence, and the same side of the lateral wall of described inner core is provided with the detent of two-layer correspondence.One end of spring is against with on corresponding registration mast, and the other end of described spring is all embedded on corresponding detent.By arranging two-layer spring along the axis of inner core, there is the good advantage of load-carrying capacity, improve service life.

In the above-mentioned latter in bush of swing arm, described inner core and described urceolus all adopt stainless steel material to make.Inner core and described urceolus all adopt stainless steel material to make, and have and not easily get rusty and the good advantage of result of use.

Compared with prior art, this rear-swing arm lining has the following advantages:

1, be provided with elastic rubbery body and the radial spring arranged between inner core and urceolus, make this rear-swing arm lining have the ability of carrying radial stress preferably;

2, the lateral wall undulate of inner core, is convenient to the connection making inner core and elastic rubbery body, has location failure-free advantage;

3, spring is all in compressive state, and when then radial forces, predetermincd tension and the radial forces of corresponding spring offset, and have and carry radial forces preferably, improve the load-carrying capacity of this rear-swing arm lining.
