Brief description is made to the content expressed by each accompanying drawing of this specification sheets and the mark in figure below:
Fig. 1 is the plan structure schematic diagram of wheel crane ear structure described in the utility model;
Fig. 2 is the sectional structure schematic diagram in the A-A face of the wheel crane ear structure described in Fig. 1;
Accompanying drawing acceptance of the bid note is respectively: 1, hanger body; 2, the left extension of body; 3, the right extension of body; 4, hanger skeleton; 5, mounting hole; 6, through hole; 7, connecting bore; 8, upper limit position block; 9, lower position block; 10, upper limit position block left-hand portion; 11, position on the right side of upper limit position block; 12, rectangular through hole; 13, positioning pin; 14, hanger body left surface; 15, hanger body right flank.
Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of detailed description of the invention of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail:
As accompanying drawing 1, shown in accompanying drawing 2, the utility model is a kind of wheel crane ear structure, described shackle structure comprises the hanger body 1 that elastomeric material is made, hanger body 1 top comprises the left extension of body 2 and the right extension 3 of body, hanger skeleton 4 is set in hanger body 1, hanger skeleton 4 is set to extend in hanger body 1 from the left extension 2 of body, extend to the structure of the right extension 3 of body again, the left extension of body 2 and the right extension 3 of body arrange a mounting hole 5 respectively, hanger body 1 is arranged the through hole 6 of H-shaped, connecting bore 7 is set above through hole 6, described shackle structure is connected with vehicle body by mounting hole 5, the suspension hook of exhaust system is hooked in the connecting bore 7 of shackle structure.Such structure, the effect bearing exhaust system weight can be realized by shackle structure, when jolting in motor-driven vehicle going process, shackle structure has can play absorption impulsive force, the exhaust system that can decay is vibrated, slow down impulsive force and damage is caused to exhaust system, play a protective role, improve level of comfort in car, the setting of said structure, owing to arranging hanger skeleton 4 in hanger body 1, the intensity of shackle structure itself can also be improved, avoid shackle structure that the problem of suspension hook play or shackle structure cracking occurs under limit force status, thus improve the reliability of whole shackle structure.
The upper limit position block 8 comprising protrusion in the through hole 6 of described shackle structure and the lower position block 9 protruded, there is gap between upper limit position block 8 and lower position block 9, connecting bore 7 is arranged on upper limit position block 8.The setting of the lower position block 9 of upper limit position block 8 and protrusion, when shackle structure in use, when car load jolts, the hanger body of elastomeric material deforms, thus the foreign impacts power of absorption band supply and exhaust system, effective attenuation impulsive force brings exhaust system vibration, slows down the damage that impulsive force causes exhaust system.
Described hanger skeleton 4 extends to the part in hanger body 1 from the left extension 2 of body, be set to the structure of passing from lower position block 9 lower position of hanger body 1, connecting bore 7 is borehole structure, on the right side of the upper limit position block left-hand portion 10 of upper limit position block 8 and upper limit position block, position 11 is all set in outwardly arcuate structure, and local increases the thickness of the rubber around connecting bore 7, such vibrational power flow, add connecting bore friction force, effectively prevent exhaust system horizontal looseness, both ensure that the reliability that shackle structure connects, shackle structure integral rigidity is made again to be in rational state, while guarantee shackle structure bulk strength and functional reliability, in turn ensure that traveling comfort in car.Described rectangular through hole 12, ensure that hanger skeleton 4 itself has good decoupling, and improve hanger cushioning performance, hanger skeleton 4 adopts metallic stamping pieces, can carry larger load, strengthens its anti-fatigue performance.
The end head of the left extension 2 of described body arranges the positioning pin 13 upwards bent, one end that hanger skeleton 4 extends in the left extension 2 of body is set to extend to the structure in positioning pin 13, such structure, guarantee that strength character is also improved in positioning pin position, it is vertically arranged structure that the left extension of described body 2 and the right extension of body 3 are set to hanger body left surface 14 and hanger body right flank 15 respectively, institute's hanger skeleton 4 is metallic stamping pieces, the hanger skeleton that metallic material is made, intensity is high, after being arranged on hanger body interior, the intensity of whole shackle structure can be improved, adapt to the working environment that shackle structure is severe, increase service life.Two mounting holes not symmetrical structure centered by connecting bore, like this, positioning pin just can play the effect of effective mistake proofing, avoids shackle structure when installing with vehicle body, and two position of mounting hole are wrongly installed.
Wheel crane ear structure described in the utility model, the effect bearing exhaust system weight can either be realized by shackle structure, when jolting in motor-driven vehicle going process, shackle structure has can play absorption impulsive force, the exhaust system that can decay is vibrated, slow down impulsive force causes damage protective effect to exhaust system, improve level of comfort in car; Wheel crane ear structure described in the utility model, owing to arranging hanger skeleton in hanger body, the intensity of shackle structure itself can also be improved, avoid shackle structure that the problem of suspension hook play or shackle structure cracking occurs under limit force status, thus improve the reliability of whole shackle structure.
By reference to the accompanying drawings exemplary description is carried out to the utility model above; the concrete realization of obvious the utility model is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasions, all in protection domain of the present utility model without to improve.
