Abstract

The utility model relates to a coaxial muffler lifting lug. The coaxial muffler lifting lug is a frameless lifting lug and composed of an elastic mounting hole, a position limit hole and a main spring. Two elastic mounting holes are arranged on the upper surface of the frameless lifting lug. The two mounting holes are symmetrically arranged on the two ends of the frameless lifting lug in parallel and a position limit block is arranged in the middle of the frameless lifting lug. Two elastic mounting holes are arranged on the two ends of the frameless lifting lug in parallel and on the premise of satisfying the intensity requirement, the distance between the position limit blocks is increased and the intensity of the lifting lug is obviously larger than the conventional way and because of the frameless lifting lug and the equal-thickness way, the position limit blocks are improved by using the frameless design to relative well satisfy the requirement and greatly reduce the cost. The frameless lifting lug has features of large vertical static strength, small vertical dynamic strength, good high-temperature resistance, long service life and low cost.

Description

Coaxial noise silencer hanger
Technical field
The utility model relates to a kind of automotive muffler, especially a kind of automotive muffler hanger.
Background technology
Have very big vibration in the time of running car; Wherein the noise of exhaust system vibration generation accounts for significant proportion; The performance of noise silencer hanger directly influences the traveling comfort of vehicle complete vehicle, and existing technical scheme is various informative, and noise silencer will bear bigger vibration in the time of running car; Traditional hanger is as shown in Figure 1, adopts the end-thickened mode of mounting hole to increase the life-span.Travelling comfort when going in order to improve, the deficiency that the technical scheme that prior art adopts exists is: 1. material selection all is a rubber, but the quiet rigidity of vertical direction is little; 2. the dynamic stiffness of vertical direction is bigger; 3. resistance to elevated temperatures is relatively poor; 4. mostly the hanger on the present market is to have the skeleton hanger, and cost is high; 5. distance too little 6. is because traditional scheme vibration frequent between two limiting stoppers, and the hanger life-span is all lower.
Summary of the invention
The utility model is in order to solve the existing high technical matters of hanger cost, and a kind of vertical static strength is big, vertically dynamic stiffness is little, coaxial noise silencer hanger of the high life that resistance to elevated temperatures is good and provide.
For realizing above-mentioned purpose; The technical scheme of the utility model is: a kind of coaxial noise silencer hanger is exoskeletal hanger, by the elastomeric mounting hole; Limiting stopper and main spring are formed; Be characterized in: be provided with two elastomeric mounting holes above the exoskeletal hanger, two parallel symmetries in elastomeric mounting hole are positioned at exoskeletal hanger two ends, and the centre is provided with limiting stopper.
Exoskeletal hanger upper and lower faces is parallel to be the uniform thickness hanger.
The beneficial effect of the utility model: the parallel two ends, exoskeletal hanger end that are positioned at, two elastomeric mounting holes of the utility model; Satisfying under the prerequisite of requirement of strength; Increased the distance between the limiting stopper, intensity is obviously greater than than traditional approach, and adopt exoskeletal hanger and uniform thickness mode and the improvement of limiting stopper form adopted exoskeletal design; Also can meet the demands preferably, greatly reduce cost.Therefore, big, the vertical dynamic stiffness of the vertical static strength of the utility model is little, low-cost exoskeletal hanger of the high life that resistance to elevated temperatures is good.
Description of drawings
Fig. 1 is traditional hanger form scheme drawing;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the cutaway view of bowing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Like Fig. 2, shown in 3, the coaxial noise silencer hanger of the utility model, by elastomeric mounting hole 1, limiting stopper 2 and main spring are formed.
The 1 parallel two ends, end that are positioned at, two elastomeric mounting holes, the centre is provided with limiting stopper 2.
The utility model is satisfying under the prerequisite of requirement of strength, has increased the distance between the limiting stopper 2, and intensity is obviously greater than than traditional approach, because traditional scheme is difficult to meet the demands, so be mostly to have the design of skeleton.The utility model adopts the mode of uniform thickness and exoskeletal design is adopted in the improvement of limiting stopper form, and exoskeletal hanger upper and lower faces is parallel to be uniform thickness hanger (Fig. 3), also can meet the demands preferably, greatly reduces cost.
The 2 parallel hanger two ends that are positioned at, two elastomeric mounting holes as shown in Figure 2, traditional hanger is as shown in Figure 1, adopts the end-thickened mode of mounting hole to increase the life-span, and with spacing hole as shown in Figure 1; The present invention has adopted the form that waits uniform thickness hanger master spring as shown in Figure 2, has improved life-span and hanger intensity and life-span like this.
