Abstract

The utility model discloses a single-pipe bushing type upper control arm bushing, which comprises an inner pipe and a bushing wrapped outside the inner pipe, wherein the bushing is made of rubber and is bonded with the inner pipe through vulcanization; the outer walls of the openings at the two ends of the inner pipe are thickened, so that the pipe body of the inner pipe presents a circle of groove ring body, and the lining is wrapped in the groove ring body; the bush is three rings of protruding, is first arch, second arch and third arch respectively, and first arch and third arch use the second arch as the benchmark symmetry to set up, and the second arch is located the central point of control arm bush. The utility model is convenient to manufacture, saves cost and is light in weight; the axial rigidity is higher, and the radial-axial ratio is reduced.

Description

Single-pipe bushing type upper control arm bushing

Technical Field

The utility model discloses a control arm bush on single tube bush formula belongs to mechanical structure technical field.

Background

Traditional control arm bush usually comprises outer tube, inner tube and rubber, can't guarantee the lightweight of bush according to the assembly space design, and axial rigidity generally is about 180N/mm, can't realize high increase.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects, the utility model discloses a single-pipe bushing type upper control arm bushing. The axial rigidity is increased, so that the pressing force is improved; the weight of the bushing is reduced, so that the manufacturing cost and the weight of the whole vehicle are optimized, and the lightweight design is realized.

The technical scheme of the utility model as follows:

a single pipe bushing type upper control arm bushing comprises an inner pipe and a bushing wrapped outside the inner pipe,

the outer walls of the openings at the two ends of the inner pipe are thickened, so that the pipe body of the inner pipe presents a circle of groove ring body, and the lining is wrapped in the groove ring body; the bush is three rings of protruding, is first arch, second arch and third arch respectively, and first arch and third arch use the second arch as the benchmark symmetry to set up, and the second arch is located the central point of control arm bush.

Preferably, the bushing is made of rubber and is bonded with the inner pipe through vulcanization;

preferably, the first protrusion and the third protrusion have a height higher than that of the second protrusion.

Preferably, a plurality of structural ribs are arranged in the clearance groove of the first protrusion and the second protrusion and the clearance groove of the second protrusion and the third protrusion, and are symmetrically arranged.

Preferably, the number of the structural ribs is 8, and the structural ribs are uniformly distributed in the clearance grooves.

The utility model has the advantages that:

1. the manufacturing is convenient, the cost is saved, and the weight is reduced;

2. the axial rigidity is higher, and the radial-axial ratio is reduced.

Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a sectional view a-a of fig. 1.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1 and 2, a single-pipe bushing type upper control arm bushing comprises an inner pipe 1 and a bushing 2 wrapped outside the inner pipe,

the outer walls of the openings at the two ends of the inner pipe 1 are thickened, so that the pipe body of the inner pipe 1 presents a circle of groove ring body, and the lining 2 is wrapped in the groove ring body; the bushing is three circles of bulges, namely a first bulge 2-1, a second bulge 2-2 and a third bulge 2-3, the first bulge 2-1 and the third bulge 2-3 are symmetrically arranged by taking the second bulge 2-2 as a reference, and the second bulge 2-2 is positioned in the center of the control arm bushing.

Preferably, the bushing 2 is made of rubber and is bonded to the inner tube 1 by vulcanization;

preferably, the first protrusion 2-1 and the third protrusion 2-3 have a height higher than that of the second protrusion.

Preferably, a plurality of structural ribs 2-4 are symmetrically arranged in the clearance groove of the first protrusion 2-1 and the second protrusion 2-2 and the clearance groove of the second protrusion 2-2 and the third protrusion 2-3.

Preferably, 8 structural ribs 2-4 are uniformly distributed in the clearance groove.

The utility model discloses a control arm bush axial stiffness is higher, has reduced the footpath axial ratio.

Reduced radial and axial stiffness ratio case:

the axial rigidity of an old two-pipe bushing structure of a certain vehicle type is 180N/mm, and the radial rigidity 6200 +/-15N/mm:

the axial rigidity of the novel monotube lining structure of the motorcycle type is 980N/mm, the radial rigidity is 6200 +/-15N/mm,

the axial rigidity ratio of the radial direction of the present case is 34: 1 is reduced to 6: 1.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
