Abstract
The utility model provides a kind of lifting lug of automobile exhaust pipe, can solve that when lifting lug intensity requirement improves rubber compounding need to be developed again, not only R＆D costs are high, but also time-consuming and laborious technical problem.It includes lifting lug main body, it is characterised in that：It further includes band-like reinforcer, and reinforcer is around being set to lifting lug main body periphery and connect with lifting lug main body by fixed structure.
Description
Technical field
The utility model is related to automobile exhaust pipe connections fields, and in particular to a kind of lifting lug of automobile exhaust pipe.
Background technology
Lifting lug of automobile exhaust pipe is used to exhaust pipe being connected to chassis, is generally obtained by rubber system.When automobile update,
It has also been proposed higher requirement to the intensity of lifting lug, at this point, generally requiring to readjust rubber compounding, passes through rubbery intensity
It improves to ensure the raising of lifting lug intensity, not only R＆D costs are high, but also time-consuming and laborious.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of lifting lug of automobile exhaust pipe, lifting lug intensity requirement can be solved
Rubber compounding need to be developed when raising again, not only R＆D costs are high, but also time-consuming and laborious technical problem.
Its technical solution is such comprising lifting lug main body, it is characterised in that：It further includes band-like reinforcer, institute
Reinforcer is stated around being set to lifting lug main body periphery and connect with the lifting lug main body by fixed structure.
Further, the fixed structure includes being set to the groove of lifting lug main body periphery and being relatively arranged on groove
The limit journal stirrup of two side, the reinforcer are embedded in the groove and by limiting journal stirrup press fitting.
Further, the lifting lug main body is equipped with upper connecting hole and lower connecting hole, and the lifting lug main body is located at the upper company
It connects and is equipped with a perforative compression chamber between hole and the lower connecting hole, institute's compression chamber top, which is equipped with towards the lower connecting hole, to be extended
Upper limit portion, the compression chamber lower part is equipped with the lower limit portion extended towards the upper connecting hole, and the lifting lug main body is not pressed
Under contracting state, the upper limit portion is arranged with lower limit portion interval.
Further, the company that the two side of the compression chamber passes through arc shape with the upper limit portion, the lower limit portion
Socket part connects.
Further, the lower end in the upper limit portion is equipped with the recess of arc shape, and the upper end in the lower limit portion is equipped with arc
The protrusion of shape, the radian of the recess are more than the radian of the protrusion, and the depth of the recess is less than the height of the protrusion；
The lower limit portion is located at the raised both sides and is respectively equipped with plane seam allowance.
The utility model is surrounded with band-like reinforcer by lifting lug main body periphery, can effectively improve lifting lug entirety
Intensity reduce R＆D costs to avoid new rubber compounding is developed, it is time saving and energy saving.
Description of the drawings
Fig. 1 is the main structure diagram of the utility model.
Fig. 2 be Fig. 1 A-A to cross-sectional view.
Fig. 3 is the side structure schematic view of the utility model.
Specific implementation mode
A kind of lifting lug of automobile exhaust pipe, as shown in Fig. 1 ~ Fig. 3 comprising lifting lug main body 1 further includes band-like reinforcer
（It is not shown）, reinforcer is circular to be set to 1 periphery of lifting lug main body and is connect with lifting lug main body 1 by fixed structure；Gu
It includes the groove 10 for being set to 1 periphery of lifting lug main body and the limit journal stirrup 11 for being relatively arranged on groove two side, limit to determine structure
Journal stirrup 11 is integrally formed with lifting lug main body, and reinforcer is embedded in groove 10 and is pressed by limiting journal stirrup 11.
Lifting lug main body 1 is equipped with upper connecting hole 3 and lower connecting hole 2, lifting lug main body 1 be located at upper connecting hole 3 and lower connecting hole 2 it
Between be equipped with a perforative compression chamber 4,4 top of institute's compression chamber is equipped with the upper limit portion 6 that extends towards lower connecting hole 2, under compression chamber 4
Portion is equipped with the lower limit portion 5 that extends towards upper connecting hole 2, under 1 uncompressed state of lifting lug main body, upper limit portion 6 and lower limit portion 5
Interval setting；The setting of compression chamber can ensure the Static stiffness of lifting lug, improve the damping performance of lifting lug entirety, upper limit portion is under
The setting of limiting section can realize that hard nonlinear change occurs in compression process for lifting lug main body, realize overload protection.
The two side of compression chamber 4 is connect with upper limit portion 6, lower limit portion 5 by the interconnecting piece 9 of arc shape, and stress is made to disappear
Subtract more.
The lower end in upper limit portion 6 is equipped with the recess 8 of arc shape, and the upper end in lower limit portion 5 is equipped with the protrusion 7 of arc shape, recessed
Sunken radian is more than the radian of protrusion, and the depth of recess is less than the height of protrusion, and lower limit portion 5 is located at raised 7 both sides and sets respectively
There is plane seam allowance；The setting of the recess and protrusion of arc shape, i.e. primary load bearing face are cambered surface, and area is big, and load is big, while can also make
The curve rising that hard nonlinear change is not unexpected is obtained, but is seamlessly transitted with linear change, and hard nonlinear change itself
Also curved to seamlessly transit, vibration damping process can be kept gentler under the premise of ensuring overload protection.
