Abstract
The invention relates to a noise-reducing design for vehicle wheels, in particular vehicle wheels fitted with tyres. The invention also relates to a method of developing conventional wheels. According to the invention, the hollow space (6; 6a, 6b) formed by a tyre (10) and wheel rim (1) is filled with a granular, non-deformable and temperature-stable filler. The filler dampens the resonance characteristics of the hollow space and thereby substantially reduces the noise emitted by the vehicle. The hollow space can be filled completely with the filler according to the invention. In addition to the filler, a gas, such as compressed air, is also used in the known way to fill the hollow space. The filling does not noticeably affect the static and dynamic characteristics of the vehicle tyres. In addition, a special filler chamber (6b) can also be provided for the material. A second chamber (6a) is filled in the known way with filler gas and the pressure of that gas is transmitted via a diaphragm (8) to the filler and thus to the wall of the tyre (10).
Description
The present invention relates to a kind of wheel, compare, produce the noise that travels that significantly reduces with traditional wheel.The invention still further relates to a kind of process, be used to fill the inner space of tire, so that further improve traditional wheel according to the present invention.
Under present technology status, there are many wheels with different structure and profile known.It is very usual using tubeless tires on automobile.In this case, tubeless tires is placed on the wheel rim with special tool, mode is that the crimping that radially extends of tire presses the inboard that is arranged on the rim shoulder on the wheel rim periphery, thereby forms an annular tire inner space that is wrapped by the tyre and rim envelope.The inside tires space can charge certain filling gas by the valve member that is arranged on the wheel rim, generally is pressurized air.In this case, filling pressure is an important parameters for the ride characteristic of wheel.
From European patent application EP 92,103,501 as can be known, and the tire of wheel is a great noise source of automobile.Wheel travel the generation one of noise be because, each profile of tooth arch rib (profile rib) of tyre crown periodically impacts the road surface, thereby causes the periodically deforming of tire.Another mechanism that the noise that travels generates is that tire contacting surface is the compression of rubber for tire and the corresponding decompression of tire contacting surface in leaning on rear region in the forward area on travel direction.Propose in the european patent application of mentioning in the above, in order to reduce the noise that travels of motor tire, arrange each rib of crown section to be offset so vertically, the feasible difference rib of out-of-position side regions is vertically impacted the road surface in the phase deviation mode, thereby realizes for a kind of destructive interference by the sound pollution source that each side regions constituted.But, can not reach the travel effect of noise of remarkable minimizing with this means.
The objective of the invention is, further improvement is chatted a kind of wheel partly before meeting claim 1, makes its noise that travels significantly reduce, and a kind of process is provided, make in this way, further improvement according to the invention can be achieved with easy means at traditional wheel.
With regard to wheel, this purpose is to realize by the various special characteristics of claim 1.
The present invention is based on a kind of like this understanding, promptly a resonant cavity is represented in the inside tires space of wheel, and it has amplified the noise that travels significantly, and this noise comes down to that sound pollution source on the crown causes by being confined to.The present invention is also based on following understanding, promptly when the resonance effects in inside tires space by filling a kind of noise absorption filler and eliminate or when at least significantly reducing, the noise that travels can significantly reducing.For static state and the dynamic characteristics that does not change tire, with filler, inside tires charges a kind of pressurized filling gas, particularly pressurized air in a known way.Filler must have the particle conformability that adapts to squeegee action, and must not be to be with cusped edge, in order to avoid the endothelium of infringement tire.In order to ensure the filler long durability, filler must can keep its shape under the deflection of tire action, and the temperature rise that must be able to keep out when running at high speed to be occurred.
According to claim 2, filler can be full of the inside tires space basically fully.In order to charge inside tires with filler and filling gas simultaneously, can dispose the valve system of making according to claim 4 to 6.Secondly,, two discrete chambers that charge be can in the inside tires space, dispose, granular filler and filling gas are used for according to claim 7.
The various superperformances of granular filler are statement to some extent in claim 8 to 13.For this reason, preferably, filler has substantially small diameter particles size uniformly when having very high noise absorption power, and comb. is bad.As filler, various expandable plastics, particularly polystyrene, especially suitable.
With regard to process, purpose is to realize by means of the various characteristics of claim 14.
After mixing tire filling gas and granular filler, the compression filling gas also blows into the compound of filler and filling gas in the inside tires space in the time of suitably.
Claim 15 and 16 relates to the various favourable improvements of process of the present invention.
According to claim 15, preferably, during charging the inside tires space, dispose a reducing valve to remove unnecessary filling gas.If adopt a kind of foamable plastics as filler, according to claim 16, the process that a corresponding plastic foamed operation can occupy claim 14 is earlier.
The present invention is further detailed explanation below in conjunction with drawings and Examples, wherein
Fig. 1 is a section-drawing, represents first example embodiment of the periphery section of wheel of the present invention;
Fig. 2 is a section-drawing, second example embodiment of the periphery section of expression wheel of the present invention;
Fig. 3 is a detail drawing, the amplification of presentation graphs 1 and Fig. 2 regional area;
Fig. 4 A and 4B are the scheme drawings according to a kind of valve system of the present invention, as to be used to charge the inside tires space.
Fig. 1 shows first example embodiment of wheel of the present invention.Wheel rim 1 has a rim shoulder 2 in its peripheral edge margin, extend along axis direction basically, is connected with the wheel hub (not shown) via each spoke shape attaching parts 3.At its end regions, rim shoulder 2 has the wheel rim trim ring 4 and 5 that radially extends, and is connected in the crimping 11,12 of tire 10 at this place's wheel rim.For improving stability, the reinforcement that the crimping 11,12 of tire 10 can have crimping chipware 13,14 forms.At crown 15 places, the rubber coating of tire has serrate slot 16.
Rim shoulder 2 and tire 10 define an inside tires space 6, with the air tight manner sealing, can charge certain filling gas, particularly pressurized air via the valve member on the wheel rim 17.Common inflation pressure among the inner space 6 is a kind of tire special parameter, to determining that tire running characteristic tool has a significant impact.
According to the present invention, corresponding to the first embodiment of the invention that is shown in Fig. 1, inside tires space 6 be full of fully basically a kind of granular, can keep shape and the filler heatproof degree.This filler with respect to the pressurized air that is used to charge according to current techniques, has much bigger sound absorbing power, so that inside tires space 6 is subjected to acoustic damping, and its resonance effects is eliminated or be able to remarkable minimizing at least.With this filler, inside tires space 6 is filled with a kind of filling gas, particularly pressurized air, so that with respect to traditional only filled compressed-air actuated tire, the static state of tire and dynamic characteristics can not change or change not quite.The traveling comfort of taking thereby will never be restricted because of filler.By means of the particle conformability (granular concistency) of filler, this is very important for purposes of the invention, has guaranteed that filler can adapt to the distortion at each stage tire of tyre rotation.With respect to carrying out the expanded cellular rubber filling in inside tires space with the either large or small material of a kind of elasticity, according to the present invention be with the advantage that a kind of granulated filler filling inside tires space has, filler can not destroyed by the deflection energy of tire or decompose, and the deflection energy of tire at most only can cause the redistribution of filler.
With the particle conformability, the filler that also requires to be adopted be can keep shape with the heatproof degree, even in over a long time, also need so.Shape keeps and can realize by the material that adopts a kind of elastically deformable particularly.Because temperature build-up when running at high speed, thus can be high temperature resistant be very important.Certainly, equally preferably, filler has very high sound absorbing power, so that the resonance damping in inside tires space is effective especially.In order to ensure filler the distortion of tire is had good dynamic adaptable, preferably, the filler that is adopted has substantially small diameter particles size uniformly.Filler can be ball-shaped particularly, and diameter is less than 1 millimeter.But, should consider that filling gas should be able to make and oneself be evenly distributed among the inside tires space 6, and thereby tyre wall portion be applied uniform pressure.Therefore, the squeegee action that must not can be caused owing to deflection action of filler hinders flowing of filling gas.So the particle size of filler should be too not little.In the example embodiment according to Fig. 1, filler is full of inside tires space 6 basically fully.The percent by volume of filler thereby preferably reach more than 90%.
Fig. 2 shows second example embodiment of wheel of the present invention.The details of tire is described in the above with reference to Fig. 1.Be different from the example embodiment that is shown among Fig. 1, what be shown in that example embodiment among Fig. 2 has two annulars in the inside tires space charges chamber 6a and 6b.One of them, in the case for towards mating surfaces 15 charge chamber 6b, be full of the granulated filler that had illustrated already basically fully, and another charges chamber 6a, be provided with towards wheel shaft, only be full of a kind of filling gas, particularly pressurized air.Two charge chamber 6a and 6b separates by means of a membrane-like partition 8.Membrane-like partition 8 can be guaranteed two equalization of pressure that charge between chamber 6a and the 6b.Thereby the filler that can realize charging chamber 6b is subjected to charging the compressing of pressure of the filling gas of chamber 6a, is close to tyre wall portion in shape match mode.The improved shape of embodiment shown in Fig. 2 in the deformability of tire flex motion tyre during.Secondly, filler can be filled into chamber 6b when having made in that tire is firm, even also stay the there when tire changing.
But, the chamber that is full of filler also can be arranged on the side towards wheel rim.
In Fig. 3, with thin portion display of tyre inner space 6 of amplifying or the zone 9 that charges chamber 6b.In thin portion 9, can discern each particle 20 of granulated filler.Preferably, filler particles is with high-density arrangement, so that inside tires space 6 or charge chamber 6b and almost completely be full of particle.Filling gas can flow through formed hole 21 between the filler particles 20.
For unlikely quality and the moment of inertia that increases wheel significantly, a kind of plastics particularly suitable of low-density elastically deformable is made filler.A kind of expandable plastic (foamable plasti-cs material) such as polystyrene, especially can be buied by trade name Si Dailuobo (Styrop-or) (registered trade mark (RTM)), and is verified effective especially.In the time of suitably, can replenish with polystyrene and use other plastic fractions.As drive wheel materials (driver material), pentane or other hydrocarbon gas all can use.Use polystyrene as filler, can reach from 20 to 40 kilograms/meter
3Grain density.The advantage of expandable plastic is that the particle size of filler can be subjected to the influence of foam process method within a large range, and can produce relative homogeneous granules size.
For the example embodiment of the wheel of the present invention that is shown in Fig. 2, charging chamber 6a with filling gas is to know that altogether mode realizes by the valve 7 that is arranged on the wheel rim 1.The pressure control that remains to fill the filling gas in inside tires space 6 into filler that is shown in the wheel of Fig. 1 can similarly be realized via traditional valve 7.Preferably, inside tires space 6 can side by side be filled with filler and filling gas.The groundwork of required for this reason valve system simply is shown in Fig. 4 A and 4B.
Charge-filling valve 30 and pressure-modulation valve 31 imbed wheel rim 1.Charge-filling valve 30 is closed by means of spring 32 on rest position.Simultaneously, the pressure that charges in inside tires space 6 acts on the cover closing member 33.Pressure-modulation valve 31 is closed by means of cover closing member 35 equally, and this part presses the wall portion of wheel rim 1 by means of spring 34 on rest position.The pressure in inside tires space 6 also acts on the cover closing member 35.For emptying inside tires space, or, can open cover closing member 35 by means of pin 36 in order to reduce its pressure.The particle 20 that charge-filling valve 30 is designed to filler can enter the inside tires space by its cross-sectional plane, and pressure-modulation valve 31 is designed to only to be used to charge or the filling gas in emptying inside tires space.The particle of filler makes it to leave pressure-modulation valve 31 by means of filter net device 37.
Fig. 4 B show be in compound with filler particles 20 and filling gas and charge the process in inside tires space 6 with reference to the described valve system of Fig. 4 A during.With after granulated filler is mixed, compound is via arriving at charge-filling valve 30 for defeated flexible pipe 38 at the tire filling gas.Because the pressure effect of filling gas, the cover closing member 33 of charge-filling valve 30 is opened, and filling gas enters inside tires space 6 with filler particles 20.But, a kind of problem can appear in this moment, and promptly in order to carry filler particles, filler must present lower density, thereby filling gas occupies bigger volume ratio in the compound that is transferred.However, for filler particles in the inside tires space can reach desirable close packing, unnecessary filling gas must be able to be overflowed.Pressure-modulation valve 31 is exactly to serve for this purpose.To the exert pressure cover closing member 35 that just can open pressure-modulation valve 31 and emit unnecessary filling gas of pin 36.Filter net device 37 can prevent that filler particles 20 from selecting.In charging process, the density meeting of filler particles thereby increasing gradually in inside tires space 6.In case reach predetermined filler particles density, just can finish to charge process.Needed pressure of gas sealed in electric can be set up via pressure-modulation valve 31.But, the operating mode of pressure-modulation valve also can be, it is at first opened when the charging pressure and be exceeded of predetermined filling gas.
What should emphasize is, the legend that is shown in the valve system among Fig. 4 A and the 4B should be understood to just schematically, and actual technical pattern can differ widely with legend.Especially, charge-filling valve 30 and pressure-modulation valve 31 can be configured among the structural unit, specifically, and coaxial or parallel axes.
When certain foamable plastics were used as filler, the technological process that charges of inside tires cavity can be a kind of plastic foamed process of knowing altogether before.Before charging, the accessory substance (such as moisture) that is suitable for and removes (such as by oven dry) to occur with foaming.
Note the following fact, promptly by using the disposal problems that can not produce any possibility damage to the environment according to filler of the present invention.Filler can easy means recycle, and perhaps can reuse after suitably cleaning.The solution that proposes according to the present invention is not only applicable to the wheel of belt wheel tire, and is suitable for reducing significantly the noise that travels of the vehicle of any kind of, the noise of the vehicle that particularly travels in orbit.In vehicle ' situation in orbit, when charging wheel, also to consider to charge rail body and pillow body problem.
