Abstract

The invention discloses an elastic wheel which comprises an outer frame, at least two spokes and a shaft seat. The spokes are evenly disposed between the outer frame and the shaft seat and are in distorted arc structures. The spokes have the function of deformation, the same as the springs. Micro deformation of the spokes reduce vibration and also enables the stress of the outer frame to be absorbed by the deforming spokes, the outer frame evenly and flexibly deforms, and accordingly jumping is avoided and comfort is better.

Description

Elastic rim

Technical field

The present invention relates to a kind of rim structure, particularly a kind of elastic rim with elasticity spoke.

Background technology

For moving body, generally all can be at the bottom of car body installing wheel, traditional wheel is comprised of wheel rim and tire, wheel rim comprises again housing 1, some spokes 2 and axle block 3(can cooperate Fig. 6 to shown in Figure 9), tyre ring is placed on the housing, directly contact with ground, can play buffer action, alleviate vibrations, spoke then evenly is fixed in the housing inboard, and intersect at the axle block at center, and utilize the rolling of wheel, reduce to drive the power that car body moves.

Existing spoke has various structures, and tabular rib is a kind of spoke architecture wherein, because rib is durable, can play a supporting role in tire running, but the quantity of rib is usually less, causes the distortion of housing inhomogeneous.Shown in Fig. 6,7, be a kind of rim structure of tabular spoke, the wheel rim of this structure under steam, because rib 2 is durable, rib is distortion not, and the corresponding housing of rib position is not yielding yet, and housing 1 other position owing to there not being rib to support larger distortion occurs, thereby make housing form the fluctuating shape, so traveling comfort is very poor.

Fig. 8 and Fig. 9 are existing other two kinds of rim structures, the wheel rim of these two kinds of structures is identical with aforementioned wheel rim, the center superposition of the center of rib 2 and axle block 3, when wheel rim is stressed, rib 2 is supporting housing 1, support place housing is not yielding, and the distortion of support place housing is comparatively not serious, thereby affects traveling comfort.

From above-mentioned existing wheel rim force analysis under steam as can be known, why causing the under steam problem of housing fluctuating of existing wheel rim, mainly be because tabular spoke rigidity is too strong, and elasticity is not enough, and the center superposition that is subjected to force direction and spoke centre and axle block of wheel rim, not distortion of spoke when stressed only has the housing distortion that rises and falls, especially for the wheel rim of spoke negligible amounts, the state that rises and falls is even more serious, car body even can produce violent vibrations, traveling comfort is very poor, haves much room for improvement.

In view of aforementioned analysis, the design people carries out in-depth study for now widely used rim structure, and is better to obtaining a kind of elasticity, can make the distortion of housing more be tending towards circular rim structure.

Summary of the invention

Technical matters to be solved by this invention is to provide a kind of spoke elasticity that increases to make the housing distortion more be tending towards circular elastic rim, to obtaining good traveling comfort.

For solving the problems of the technologies described above, technical solution of the present invention is:

A kind of elastic rim comprises housing, at least two spokes and axle block, and described each spoke evenly is arranged between housing and the axle block; Described each spoke is the arcuate structure of distortion.

The intersection line of described spoke and axle block is defined as α with the angle of axle centre, and the intersection line of described spoke and housing is defined as β with the angle of axle centre, and α ≠ β.

Described angle α spends less than 90 greater than 0.

Described angle β spends less than 90 greater than 0.

Be provided with hollow slots on the described spoke, this hollow slots is positioned at a side of housing, thereby makes spoke present dynamic chevron pointing.

Described spoke width is widened to housing one end gradually from axle block one end.

After adopting such scheme, because the spoke that the present invention adopts is the arcuate structure of distortion, such structure is similar to the function that spring equally possesses distortion, the infinitesimal deformation function of spoke not only can play the effect of damping, the stressed of housing absorbed in the distortion of spoke, housing produces plastic deformation uniformly, does not therefore have the sensation of beating, and traveling comfort is better.

The specific embodiment

The invention will be further described below in conjunction with the drawings and specific embodiments.

Disclosed is a kind of elastic rim, as shown in Figure 1, 2, be the first preferred embodiment of the present invention.Described elastic rim comprises housing 1, three spokes 2 and axle block 3, and described each spoke 2 evenly is arranged between housing 1 and the axle block 3.Key of the present invention is: described each spoke 2 is the arcuate structure of distortion, and the intersection line of definition spoke 2 and axle block 3 is α with the angle of axle centre, and the intersection line of spoke 2 and housing 1 is β with the angle of axle centre, and α ≠ β.

In order more to prepare explanation angle α and β, to consult shown in Figure 1ly, described axle centre is L.Described spoke 2 and axle block 3 intersect actual for face crossing, and both intersection lines to be defined as the geometric center lines of phase cross surface be L ₁Because axle block 3 is circular, so L ₁May also may be camber line for straight line; Work as L ₁During for straight line, it is parallel with L reality, and both angle α are 0 degree; Work as L ₁During for camber line, α is L ₁The angle of place face and L.It is also crossing for face that in like manner described spoke 2 and housing 1 intersect reality, and both intersection lines to be defined as the geometric center lines of phase cross surface be L ₂Because housing 1 also is circular, so L ₂May or be camber line for straight line also; Work as L ₂During for straight line, it is parallel with L, and both angle β are 0 degree; Work as L ₂During for camber line, β is L ₂The angle of place face and L.L among the figure ₁' be camber line L ₁Move to the tangent line of the intersection point that intersects with L in the isoplanar, α is L ₁' with the angle of L; In like manner, L ₂' be camber line L ₂Move to the tangent line of the intersection point that intersects with L in the isoplanar, β is L ₂' with the angle of L.
