Abstract
The utility model discloses a support used on the gas exhaust brake pipe or valve of a vehicle engine. The fastening end of the support is thicker than the stress end of the support. The thickness of the support is gradually increased from the fastening end to the stress end. By increasing the thickness of the fastening end and utilizing the mechanics characteristic of the cantilever beam type support, the utility model enables the thickness of the part of the support with large stress to be also increased, increases the tensile strength of the support, and is breakage proof; as a limiting boss and a dustproof boss are additionally arranged, the utility model not only increases the stressed area of the support and further increases the limiting and dustproof function, but also prevents the trembling of the support, improves the reliability and durability of the gas exhaust brake pipe or valve and further ensures the braking performance of the whole vehicle; the effect is reliable, which is proved with testing.
Description
(1) technical field
The utility model relates to a kind of automobile brake part, the support on particularly a kind of automobile engine to exhaust Brake pipe or the valve.
(2) background technique
The support current, that automobile engine to exhaust Brake pipe or valve use is to adopt steel plate to manufacture through stamping process.Arm is thick everywhere is the same for the support that is obtained, and the loading characteristic of support is to increase gradually from the force side to the fastening end, can not cater to the loading characteristic of the overhang form of support, when support approaches, the support fracture in use often occurs, cause exhaust brake to lose efficacy, and influence the car load braking.When support is thick, cause waste, and weight is big.Moreover this support do not have dust guard, can't avoid dirt to enter Brake pipe (valve), enters the dirt of Brake pipe (valve), can accelerate to wear and tear between pitman arm shaft and the setting sleeve, causes support force inhomogeneous, therefore the working life of reducing Brake pipe (valve).The support fastening end that stamping process is made only relies on two bolton, and insufficient strength when handling cylinder working, is trembleed near two bolts, also causes the support fracture easily.
(3) summary of the invention
The technical problems to be solved in the utility model is: the automobile engine to exhaust Brake pipe of not easy-rupturing of a kind of reliability and good endurance or the support on the valve are provided.
In order to solve the problems of the technologies described above, the fastening end of the utility model support is thicker than the force side.
In order to utilize the loading characteristic of support, the tensile strength that can improve support is waste material not again, and described support increases gradually from the force side to fastening end thickness.
In order to increase lifting surface area, and support is not trembled, the inner of described fastening end upper shaft hole is provided with positioning boss.
In order to increase lifting surface area, and increase dust reduction capability, the outer end of described fastening end upper shaft hole is provided with dustproof boss.
Easy for processing, described support adopts precision casting or contour forging technique to make.
The beneficial effects of the utility model are: the utility model strengthens the thickness of fastening end, utilizes the mechanics feature of the support of overhang form, makes the big local thickness of support force also big, increases the tensile strength of support, so easy-rupturing not; Have additional positioning boss and dustproof boss, the lifting surface area that had both increased support to be to have increased locating function and dust reduction capability, can also prevent that support from trembling; Improve the reliability and the durability of exhaust brake pipe or valve, until guaranteeing braking performance of vehicle; Through evidence, reliable for effect.
(4) description of drawings
Fig. 1 is the utility model structural representation; Fig. 2 is the complete section diagrammatic sketch of Fig. 1;
Wherein: 1, fastening end, 2, the force side, 3, axis hole, 4, attachment hole, 5, dustproof boss, 6, positioning boss.
(5) embodiment
A kind of automobile engine to exhaust Brake pipe as shown in Figure 1 or the support on the valve have an axis hole 3 at the middle part of its fastening end 1, are provided with attachment hole 4 in the both sides of axis hole 3, and an attachment hole 4 is arranged in the force side of support.
As shown in Figure 2, support is 21 thickenings gradually to the fastening end from the force side, are provided with positioning boss 6 in the inner of axis hole 3, are provided with dustproof boss 5 in the outer end of axis hole 3.
This support adopts precision casting or contour forging technique to make.
During use, positioning boss 6 is embedded in the axis hole on Brake pipe or the valve, plays the location and does, and dustproof boss 5 can fence up the spring that is located in the axis hole of support, plays dustproof effect, and the end face of positioning boss 6 and dustproof boss 5 is stressed, has increased lifting surface area.
Claims (4)
1. the support on automobile engine to exhaust Brake pipe or the valve, it is characterized in that: the fastening end of described support (1) is thicker than force side (2).
2. the support on automobile engine to exhaust Brake pipe according to claim 1 or the valve is characterized in that: (2) (1) thickness increases described support gradually to the fastening end from the force side.
3. the support on automobile engine to exhaust Brake pipe according to claim 2 or the valve is characterized in that: the inner of described fastening end (1) upper shaft hole (3) is provided with positioning boss (6).
4. according to the support on claim 2 or 3 described automobile engine to exhaust Brake pipes or the valve, it is characterized in that: the outer end of described fastening end (1) upper shaft hole (3) is provided with dustproof boss (5).
