Abstract

The utility model relates to a special shaped cross-section spring used for the shaking avoidance of the vehicles, in particular to a special non-round cross-section spring used in the vehicle field. The cross section of the spring adopts a special shape design different from the round shape. The shape of the cross section takes the shape of a rectangular, a trapezoid, a single-side arc or an oval, with each of the shape enabling the spring to have a combination of a multiple functions or a plurality of functions in the multiple functions, such as the increase of progress when the free heights are the same, the break-down prevention after the increase of the force bearing area, the decrease of the weight when the progresses are synchronous, the increase in the force bearing, the lengthening of the service period due to the great external force bearing capability, or the position in an extremely small space.

Description

The section spring of vehicle shock absorber special use

Technical field

The utility model relates to the section spring of a kind of vehicle shock absorber special use, is meant especially after a kind of change spring Section Design, has lightweight, stroke increase and improves the section spring of the vehicle shock absorber special use of functions such as meeting with stresses.

Background technique

Generally; at the employed shock-proof spring of vehicular field all is the shape that adopts circular cross section; the shock-absorbing special purpose spring in fields such as automobile, locomotive or bicycle for example; but the spring of circular cross section runs into the restriction that meets with stresses through regular meeting; or actuating length deficiency; spring is long and overweight, and existence is installed not all roses and cost improves relatively, does not meet shortcomings such as economic benefit.

The model utility content

Main purpose of the present utility model is to provide the section spring of the non-circular section of a kind of vehicle shock absorber special use.

According to above-mentioned purpose, the employed section spring of vehicle professional domain of the present utility model, the section configuration of described section spring can be the spring of multiple section configurations such as rectangle, trapezoidal, avette or monolateral arc, has multifrequency natures such as lightweight and stroke are bigger.

Spring with rectangular cross section, under identical spring length comparison condition, comparable coil component spring increases by 15%～35% stroke, and if in next 10%～30% the weight that reduces of the comparison condition of identical stroke, the advantage that have that stroke is big, lightweight and cost reduces significantly.

Spring with trapezoidal cross-section, basically except identical aspect the big characteristic of lightweight and stroke with the rectangular cross section spring, can bear bigger stress again, comparable circular cross section spring improves 5% applied stress or meets with stresses, can avoid elastic fatique or fracture greatly because meet with stresses, its safety in utilization is higher and working life is longer.

Spring with monolateral arc-shaped sections, under the comparison condition of equal length, also comparable circular cross section spring increases stroke, and if reduce weight and can reach lightweight, stroke equally to reach cost greatly low in that the comparison condition of identical stroke is next.

Spring with avette section, though rectangle and trapezoidal cross-section spring are unobvious as described above for the characteristic that its lightweight and stroke increase, but the spring than circular cross section is superior, and avette section configuration is compared down with other section, can significantly improve the problem that applied stress is concentrated, promptly according to avette cross section characteristic, it can more disperse applied stress in use, therefore can satisfy the demand condition of higher stress, and can increase the service life, can be installed in the place that needs small volume but will long stroke especially.

Embodiment

As seen from the figure, the utility model is the section spring of a kind of vehicle shock absorber special use, the section configuration of this spring is non-circular section, thereby reach lightweight, stroke is big, cost is low, the effect of the good and long service life of Security, then make a general reference the machine automobile as for general vehicle, the traffic tool such as locomotive or bicycle, so particularly instigating, the utility model is used in automobile, on the specialized field of locomotive or bicycle shock absorber, installation position and notion as for general automobile or locomotive shock absorber are mature technology, no longer described in detail at this, characteristics of the present utility model mainly are that described section includes rectangular cross section at least, trapezoidal cross-section, multiple shape sections such as avette section and monolateral arc-shaped sections.

As Fig. 1, be the first enforcement schematic representation of the present utility model, as shown in Figure 1, spring section of the present utility model is a rectangular cross section 1, if spring of the present utility model is compared with the circular cross section spring, rectangular cross section spring of the present utility model and circular cross section spring are under the comparison condition of identical springs length, comparable circular cross section spring increases by 15% to 35% stroke, and if under the comparison condition of identical stroke, can significantly reduce by 10% to 30% weight, described stroke is meant in certain spring installing space, remaining length space when the spring tight compression.

As Fig. 2, be the second enforcement schematic representation of the present utility model, as shown in Figure 2, this spring section is a trapezoidal cross-section 2, except the big characteristic of lightweight and stroke is identical with the rectangular cross section spring, can bear bigger stress again basically, comparable circular cross section spring improves 5% applied stress, big because meet with stresses, so be difficult for producing elastic fatique or fracture, it is safe to use and the life-span is longer.

As shown in Figure 3, be the 3rd embodiment's schematic representation of the present utility model, as shown in Figure 3, this spring section is monolateral arc-shaped sections 3, compare with the circular cross section spring, under the comparison condition of equal length, also comparable circular cross section spring increases stroke, if and, have lightweight, stroke and reach the low characteristics of cost greatly in the next weight that reduces of identical stroke comparison condition.

As shown in Figure 4, be the 4th embodiment's diagrammatic sketch of the present utility model, as shown in Figure 4, this spring section is avette section 4, be better than the circular cross section spring aspect lightweight and the stroke increase, because circular cross section spring stress when action concentrates on the immovable point on the spring inside diameter edge, when overstep the extreme limit service time, make spring breakage easily, avette section can significantly reduce the problem that other section stress is concentrated in use, applied stress can be disperseed, therefore heavily stressed place can be used in, and the working life of spring can be prolonged.

The above is preferred embodiment of the present utility model only, is not to be used to limit protection domain of the present utility model.
