Description

The wheel rim of wheel

Technical field

The utility model relates to a kind of wheel rim of wheel, especially for the wheel rim of automotive wheel.

Background technology

At present energy-conservation is all goals to fight for of all trades and professions, in the automobile design industry, reducing oil consumption is a critical index of vehicle design, therefore, on the basis of the using property data that does not reduce parts, if can reduce the parts quality, then can reach the purpose that reduces complete vehicle weight and then reduce oil consumption.

Wheel rim is the vitals in the automotive wheel, is used for cooperating with tire, with support tire.One side of wheel rim supports by with axle wheel the bonded assembly spoke being installed, and wheel rim and spoke can form as one.Wheel rim and tire play the effect of the weight of carrying vehicle in the lump, and the inertia in bearing driving and braking.During, emergency brake curved excessively at vehicle, wheel rim can be born most inertia deformation power to guarantee the ride comfort of driving and braking.Therefore wheel rim can be subjected to bigger stress usually.In existing wheel rim (for example inner tube free drop-center rim), its integral thickness is normally uniform, in order to reduce the stress that wheel rim integral body is subjected to, realizes by the thickness that increases whole wheel rim usually.

The utility model content

The purpose of this utility model is to provide a kind of wheel rim of wheel, by improvement to the structure of this wheel rim, make under the situation of the load-carrying capacity (promptly reducing the stress that this wheel rim integral body is subjected to) that improves this wheel rim, farthest reduce the increase of wheel rim on weight.In other words, under the situation of the load-carrying capacity (stress that it bore) that keeps this wheel rim, can alleviate the weight of this wheel rim, thereby reach the purpose that reduces complete vehicle weight and then reduce oil consumption.

The wheel rim of the wheel that provides according to a kind of embodiment of the present utility model along the rim width direction comprise first sidepiece near wheel spoke, away from second sidepiece and the pars intermedia between this first sidepiece and second sidepiece of this wheel spoke, wherein, the thickness of described first sidepiece and/or described second sidepiece is greater than the thickness of described pars intermedia.

Contriver of the present utility model adopts finite element (CAE) analysis method that the stress that wheel rim is subjected to is analyzed, creatively find: for the uniform wheel rim of thickness, it is being uneven along the stress that is subjected on the rim width direction, but the stress that the stress that is subjected on described first sidepiece of wheel rim and described second sidepiece obviously is subjected to greater than described pars intermedia is wanted about a big order of magnitude usually.Thereby, in order to reduce the stress that wheel rim integral body is subjected to, be unnecessary if increase the thickness of whole wheel rim equably.Contriver of the present utility model finds by cae analysis, even if only increase the thickness of one in described first sidepiece and described second sidepiece, under the identical situation of thickness increment, just almost can reach the effect of the stress reduction that is realized when integral thickness evenly increases.

Therefore, in the wheel rim of the wheel that above-mentioned embodiment of the present utility model provided, by making at least one thickness in described first sidepiece and described second sidepiece greater than the thickness of described pars intermedia, realized under the situation of the load-carrying capacity (promptly reducing the stress that this wheel rim integral body is subjected to) that improves this wheel rim, farthest reducing the increase of wheel rim on weight, thereby finally reached the purpose that reduces complete vehicle weight and then reduce oil consumption.
