Description

Reinforcement heat radiation wheel rim with convex tendon

Technical field

The utility model relates to a kind of rim for automobile wheel, and particularly a kind of is the reinforcement heat radiation wheel rim with convex tendon of characteristics with the cross-sectional plane.

Background technology

Wheel rim of the prior art comprises that the limited wheel sidewall is to the arcuate leg that moves and the bead seat of supporting tire, bending is connected arcuate leg with bead seat, be provided with along the circumferential parallel interval distribution of wheel rim convex tendon in the junction of turning round of arcuate leg and bead seat, to prevent that wheel rim from causing the wheel rim insufficient strength cracking to be occurred because of arcuate leg is connected the stress problem with turning round of bead seat, the generation of problems such as fracture, but, because vehicle wheel tyre in the process of moving can produce a large amount of heats, these heat accumulations on wheel difficulty distribute, and these heats can cause the accelerated weathering of tire, shorten its service life.

Invention constitutes

The purpose of this utility model is to overcome weak point of the prior art and a kind of intensity that both can guarantee wheel rim is provided, can plays the reinforcement heat radiation wheel rim with convex tendon of thermolysis to wheel.

The purpose of this utility model realizes by following approach.

Reinforcement heat radiation wheel rim with convex tendon, comprise bead seat, arcuate leg and spaced apart in the turn round convex tendon of junction of bead seat and arcuate leg along the wheel rim circumferencial direction, its structural feature is: convex tendon comprises first convex tendon and second convex tendon, first convex tendon and second convex tendon correspondence respectively are distributed on bead seat and the arcuate leg, and first convex tendon and second convex tendon all favour the intersection line of bead seat and arcuate leg.

Like this, during wheel, first convex tendon is subjected to the power perpendicular to this first convex tendon, therefore, this power on the periphery of bead seat, can be decomposed into one along the axial component and one of wheel rim along the circumferential component of bead seat, can produce along the axial wind of wheel rim along the axial component of wheel rim, thereby the heat on the wheel rim bead seat is dispelled, to reduce the temperature of wheel rim; Simultaneously, when wheel rim is rotated, the suffered power of second convex tendon also can be decomposed into along arcuate leg radially component and along the tangential component of arcuate leg, and also can produce along arcuate leg wind radially along arcuate leg component radially, thereby the heat on the arcuate leg is dispelled, further reduce the temperature of whole wheel, prolong the service life of wheel.

In addition, because first convex tendon produces along the axial power of wheel rim, second convex tendon produces along arcuate leg periphery power radially, like this, two power mutual actions, thus make the wind that forms on bead seat and the arcuate leg produce the effect of agitating, so that wind speed is accelerated, in wheel rim, produce the more powerful wind effect of stirring, quicken distributing of wheel heat, and these all are the unexpected effects of the utility model.

The purpose of this utility model can also realize by following approach.

First convex tendon and the equal tilt distribution of second convex tendon, therefore, first convex tendon and second convex tendon can tilt in the same way, also can reversal dip.

First convex tendon and second convex tendon are along same direction inclination and be a kind of " ㄑ " shape.

Like this, when when arcuate leg is seen toward the bead seat direction, the rotation of wheel anticlockwise direction at this moment, produces the wind that spatial vertical liquidates at arcuate leg periphery and bead seat periphery intersection; The wheel right-hand revolution at this moment, then produces the wind that spatial vertical deviates from mutually at the arcuate leg face with bead seat periphery intersection, certainly, no matter is the wind that liquidates, the wind that still deviates from mutually, thus form turbulent flow, make the mobile acceleration of air.

First convex tendon and second convex tendon along opposite direction tilt and be a kind of " " shape.

Like this, the rotation of no matter wheel right-hand revolution, or anticlockwise direction can both form power in the same way on arcuate leg periphery and bead seat, reflux thereby form, and quickens the mobile of bead seat surface air, reaches cool effect.

Can strengthen the intensity of wheel rim at bead seat and the arcuate leg fixing convex tendon in junction that turns round, therefore, should distribution convex tendon as much as possible in the corner, the thickness of convex tendon is big as far as possible, to strengthen the intensity of wheel rim, like this:

The width of first convex tendon and the second convex tendon junction is greater than the width of first convex tendon and second convex tendon.

Like this, not only make the junction of turning round have enough intensity, simultaneously, thereby just the local width that strengthens convex tendon can either saving in material in the junction of turning round, and first convex tendon and second convex tendon that convex tendon extends on arcuate leg and bead seat have the fine wind action of stirring again.

The thickness of first convex tendon and the second convex tendon junction is greater than the thickness of first convex tendon and second convex tendon.

Like this, rim for automobile wheel not only has enough intensity and heat-dissipation function, simultaneously again can saving in material.

The cross sectional shape of convex tendon can have more options:

The cross-sectional plane of convex tendon can be a rectangle, also can be triangle, also can be trapezoidal.

Certainly, when the cross-sectional plane of convex tendon be shaped as rectangle the time, than being easier to processing; Consider then to be best from stressed angle with trapezoidal.

In sum, the utility model has the following advantages compared to existing technology: convex tendon can make wheel strength strengthen, and the bevelled convex tendon produces axial wind-force, and the wind-force mutual action that two convex tendons are produced, generation is agitated, and wind speed is accelerated, thereby the wind effect is stirred in bigger reinforcement, wheel temperature being reduced, increase the service life, is a kind of wheel rim of strengthening the heat-dissipation effect that has.
