Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
The helical spring vibration isolator of this automotive suspension can be arranged between helical spring 6 one or both ends and spring seat, and the helical spring vibration isolator of this automotive suspension comprises body 1, attachment face 2 and butting section 3.
Specifically, as shown in Figures 2 and 3, attachment face 2 is positioned at the interior edge face of body 1, and its shape is the spirality matched with helical spring 6 end shape.It is inner that butting section 3 is positioned at body 1, and vertical with attachment face 2, butting section 3 is provided with at least two projections 31.Preferably, the quantity of projection 31 is 2 ~ 4, and the structure of projection 31 and quantity meet the minimum breakaway force of helical spring 6 and processing technology requirement.Make the location of helical spring 6 more reliable, and reduce assembling load, be convenient to the assembling of helical spring 6.As shown in Figure 4, in the present embodiment, the quantity of projection 31 is two, and is integral type structure with body 1, and easily manufactured, processing cost is lower.
As shown in Figure 1, attachment face 2 on body 1 coincide with the end shape of helical spring 6, butting section 3 for improving the radial stability of helical spring 6, and makes helical spring 6 and body 1 interference fit by projection 31, and then makes helical spring 6 become to be integrated with spring vibration isolation pad.Preloading contracting when helical spring 6 is static, vibration isolator is resisted against on spring seat under the spring-force driven dual of helical spring 6, and when in vehicle traveling process, wheel is vertically beated up and down, helical spring 6 load changes thereupon, and helical spring 6 departs from spring seat or moves towards spring seat.In this process, helical spring 6 is located with vibration isolator all the time, decreases the injury that the shock of helical spring 6 end to spring seat and vibration isolator causes.
As shown in Figure 1, the exterior edge face of body 1 is uniformly distributed circumferentially several vent slots 4, the side of the through body 1 in vent slot 4 outer end.Preferably, have fillet 5 between the exterior edge face of body 1 and side, vent slot 4 outer end extends to fillet 5 place.When vibration isolator along with helical spring 6 moves up and down in process, the outer end of vibration isolator and spring seat Contact, the air of surface of contact compression can be discharged from the side by vent slot 4, reduces vibration isolator and contacts the noise produced with spring seat.
As Fig. 5 and Fig. 6, in the present embodiment, the quantity of vent slot is 10, and the angle namely between adjacent two vent slots is 36 °.The degree of depth of vent slot is 1/5 ~ 1/3 of body 1 thinnest part thickness, and the width of vent slot is the degree of depth 3 ~ 5 times, and the air between vibration isolator and spring seat can be discharged more rapidly, reduces the noise that in vent slot, air-flow produces.Preferably, when the degree of depth of vent slot is 1/4 of body 1 thinnest part thickness, the width of vent slot is the degree of depth 4 times, the endurance quality of vibration isolator is better.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
Although more employ the terms such as body 1, attachment face 2, butting section 3, projection 31, vent slot 4, fillet 5, helical spring 6 herein, do not get rid of the possibility using other term.These terms are used to be only used to describe and explain essence of the present utility model more easily; The restriction that they are construed to any one additional is all contrary with the utility model spirit.
