Description
Technical field
The utility model relates to a kind of torque rod bushing, in particular to a kind of torque rod bushing with long service life.
Background technique
Torque rod bushing is the torque arm both ends for acting on automobile chassis bridge, plays damping, buffering and for guide and biography
The effect of power.
And so the middle part of existing torque rod bushing axis is head, as elastic rubbery body is made by external torsion
It is easy degumming with the land portions of the extension of time, axis, once land portions generate degumming, torque rod bushing also just loses damping
Effect.And existing torque rod bushing will lead to shell breakage when by larger pressure, influence its normal use.For this purpose, I
Propose a kind of torque rod bushing with long service life.
Utility model content
The main purpose of the utility model is to provide a kind of torque rod bushings with long service life, can effectively solve background
The problems in technology.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of torque rod bushing with long service life, including central spindle and rubber sleeve, the rubber sleeve are wrapped in central spindle surface, institute
Stating central spindle surface inserting has limit baffle and anti-slip protrusion, the rubber sleeve to be coated with polyurethane set, the polyurethane set
Surface hitch is equipped with metal shell.
Further, two end surfaces of metal shell, which buckle, is equipped with sealing ring, and the sealing ring surface inserting has
Hook is limited, the limit hook buckle is installed on inside metal shell.
Further, nylon fiber silk is inlaid with inside the rubber sleeve, the metal shell surface hitch is equipped with tightly
Gu ring.
Further, two end surfaces of central spindle are inlaid with limit stop block, and limit stop block and be located at rubber sleeve side.
Compared with prior art, the utility model has the following beneficial effects:
1, this kind of long service life and the torque rod bushing with superpower retentivity pass through the limiting block of central spindle surface inserting
Piece and anti-slip protrusion can increase central spindle and the direct contact area of rubber sleeve, avoid the feelings for leading to central spindle degumming when torsion is too strong
Condition occurs, and by the nylon fiber silk inlayed inside rubber sleeve, enhances the toughness of entire rubber sleeve, rubber sleeve is avoided to break
The case where splitting strengthens the zygosity between rubber sleeve and metal shell, simultaneously by the polyurethane set on rubber sleeve surface
Polyurethane covers wear-resisting property and weatherability is strong, indirectly improves the service life of entire torque rod bushing.
2, this kind of long service life and the torque rod bushing with superpower retentivity pass through two end surfaces of metal shell and block
The sealing ring for detaining installation can be sealed positioning to the rubber sleeve and polyurethane set being located in metal shell, and torque rod bushing is avoided to exist
The case where rubber sleeve and polyurethane set compression are subjected to displacement in use process appearance, is installed tight by metal shell surface hitch
Gu ring strengthens the intensity of metal shell, the situation for leading to metal shell breakage because metal shell internal pressure is excessive is avoided to go out
Existing, the limit stop block inlayed by two end surfaces of central spindle is convenient further to position to rubber sleeve, prevents it from position occur
Shift one's love condition.
Detailed description of the invention

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of torque rod bushing with long service life, including central spindle 1 and rubber sleeve 4, the rubber sleeve 4 wrap
It is wrapped in 1 surface of central spindle, 1 surface inserting of central spindle has limit baffle 2 and anti-slip protrusion 3, the rubber sleeve 4 to be coated with poly-
Amine rouge set 6, the polyurethane cover 6 surface hitch and are equipped with metal shell 7.
In the present embodiment, as shown in Fig. 2, can be to being located at by the sealing ring 8 that 7 liang of end surfaces of metal shell buckle installation
Rubber sleeve 4 and polyurethane set 6 in metal shell 7 are sealed positioning, avoid torque rod bushing rubber sleeve 4 in use
The case where being subjected to displacement with 6 compression of polyurethane set appearance.
Wherein, 7 liang of end surfaces of the metal shell, which buckle, is equipped with sealing ring 8, and 8 surface inserting of sealing ring is limited
Position hook 9, the buckle of limit hook 9 are installed on inside metal shell 7.
In the present embodiment, as shown in Fig. 2, enhancing entire rubber by the nylon fiber silk 5 inlayed inside rubber sleeve 4
The toughness of set 4, the case where avoiding rubber sleeve 4 from rupturing, by the dead ring 11 of 7 surface hitch of metal shell installation,
The intensity for strengthening metal shell 7 avoids going out because of the excessive situation for leading to the breakage of metal shell 7 of 7 internal pressure of metal shell
It is existing.
Wherein, nylon fiber silk 5 is inlaid with inside the rubber sleeve 4, the 7 surface hitch of metal shell is equipped with fastening
