Description

Колесо для бескамерных шин с разборным ободом  Wheel for tubeless tires with collapsible rim
Предлагаемая полезная модель относится к транспортным средствам, в частности, к колесам с разборным ободом и может найти применение при про- изводстве колес для большегрузных автомобилей. The proposed utility model relates to vehicles, in particular to wheels with a collapsible rim, and may find application in the manufacture of wheels for heavy vehicles.
Известно автомобильное колесо с ободом для пневматических шин (а.с. N° 279351, опубл. 30.03.1981 г.).  Known automobile wheel with a rim for pneumatic tires (AS N ° 279351, publ. 30.03.1981).
Обод колеса содержит бортовые закраины с наклонной к середине обода по- верхностью посадочной полки. Максимально удаленный от оси вращения обода участок наклонной поверхности расположен в средней зоне посадочной полки под бортом шины, а близлежащая к закраине часть полки выполнена с посте- пенным уменьшением ее высоты к бортовой закраине.  The wheel rim contains side flanges with the surface of the landing flange inclined toward the middle of the rim. The portion of the inclined surface maximally distant from the axis of rotation of the rim is located in the middle zone of the landing flange under the tire bead, and the part of the shelf adjacent to the flange is made with a gradual decrease in its height to the flange.
Недостатком данного автомобильного колеса является недостаточная надежность закрепления бескамерной шины на ободе и герметизация ее внут- ренней полости.  The disadvantage of this car wheel is the insufficient reliability of fixing the tubeless tire to the rim and the sealing of its inner cavity.
Наиболее близким решением является колесо транспортного средства для бескамерных шин с разборным ободом по патент РФ на полезную модель jN° 115304, содержащее основание обода с посадочными полками для шины и мон- тажным ручьем, по меньшей мере, одно бортовое кольцо, замочное или борто- замочное кольцо. Согласно полезной модели, поверхность посадочных полок выполнена тороидальной или трапециевидной или ступенчатой, или треуголь- ной формы, максимальный диаметр посадочных полок в зоне контакта с шиной смещен в направлении оси симметрии шины или бортовой закраине относитель- но средней зоны посадочной поверхности шины, а участки в направлении оси симметрии шины выполнены в виде тороидальных или наклонных или горизон- тальных поверхностей, при этом все указанные поверхности выполнены с обеих сторон обода или только у одной из его бортовых закраин.  The closest solution is the wheel of a vehicle for tubeless tires with a collapsible rim according to the patent of the Russian Federation for utility model jN ° 115304, containing the base of the rim with landing shelves for the tire and mounting creek, at least one side ring, key ring or side lock ring. According to a utility model, the surface of the landing shelves is made of a toroidal or trapezoidal or stepped or triangular shape, the maximum diameter of the landing shelves in the tire contact zone is displaced in the direction of the axis of symmetry of the tire or side flange relative to the middle zone of the tire seating surface, and the sections in the direction of the axis of symmetry of the tire is made in the form of toroidal or inclined or horizontal surfaces, while all of these surfaces are made on both sides of the rim or only one of its side x rim.
Указанное решение по патенту К 115304 выбрано заявителем в качестве прототипа.  The specified decision on patent K 115304 selected by the applicant as a prototype.
Недостатком прототипа является то, что при увеличении нагрузки на колесо или/и увеличении давления в шине, вероятность самопроизвольного выхода из зацепления с ободом и разгерметизация очень велика, так как поверхность кон- такта замочного кольца с шиной невелика - шина не касается, либо незначи- тельно касается замочного кольца. The disadvantage of the prototype is that with an increase in the load on the wheel and / or an increase in tire pressure, the likelihood of spontaneous exit the engagement with the rim and depressurization is very large, since the contact surface of the locking ring with the tire is small - the tire does not touch or slightly touches the locking ring.
Технической задачей, на решение которой направлена заявляемая полезная модель, является создание надежного колеса транспортного средства для беска- мерных шин с разборным ободом.  The technical problem to which the claimed utility model is directed is to create a reliable vehicle wheel for tubeless tires with a collapsible rim.
Техническим результатом является повышение надежности эксплуатации колеса за счет снижения риска разгерметизации при больших нагрузках и давле- нии в шине.  The technical result is to increase the reliability of operation of the wheel by reducing the risk of depressurization at high loads and tire pressure.
Заявленный технический результат достигается тем, что в колесе транспорт- ного средства для бескамерных шин с разборным ободом, содержащем основа- ние обода с посадочными полками для шины и монтажным ручьем, бортозамоч- ное устройство, при этом поверхность посадочных полок выполнена тороидаль- ной формы, максимальный диаметр посадочных полок находится в зоне контак- та с шиной. Согласно полезной модели замочная часть бортозамочного устрой- ства выполнена с увеличенным сечением вдоль горизонтальной оси вращения колеса в направлении вертикальной оси шины таким образом, чтобы ширина участка контакта шины с замочной частью бортозамочного устройства составля- ла не менее величины радиуса борта шины в зоне контакта.  The claimed technical result is achieved by the fact that in the wheel of a vehicle for tubeless tires with a collapsible rim containing the base of the rim with landing shelves for the tire and mounting cradle, a locking device, while the surface of the landing shelves is made of a toroidal shape, the maximum diameter of the landing shelves is in the contact zone with the tire. According to a utility model, the locking part of the locking device is made with an enlarged section along the horizontal axis of rotation of the wheel in the direction of the vertical axis of the tire so that the width of the contact area between the tire and the locking part of the locking device is not less than the radius of the tire bead in the contact zone.
Наличие основания обода с посадочными полками для пшны и монтажным ручьем, бортозамочного устройства способствует надежному креплению шины на ободе, а, следовательно, обеспечивает надежную эксплуатацию колеса.  The presence of the base of the rim with landing shelves for millet and mounting stream, locking device contributes to the reliable fastening of the tire on the rim, and, therefore, ensures reliable operation of the wheel.
Выполнение поверхности посадочных полок тороидальной формы, макси- мальный диаметр которых расположен в зоне контакта с шиной, позволяет обес- печить надежность закрепления шины и герметизацию ее внутренней полости, тем самым обеспечивает надежность эксплуатации колеса за счет снижения рис- ка разгерметизации при больших нагрузках и давлении в шине.  The implementation of the surface of the landing flanges of a toroidal shape, the maximum diameter of which is located in the contact zone with the tire, allows to ensure reliable fastening of the tire and sealing of its internal cavity, thereby ensuring reliable operation of the wheel by reducing the risk of depressurization at high loads and pressure in the tire.
Выполнение замочной части бортозамочного устройства с увеличенным се- чением вдоль горизонтальной оси вращения колеса в направлении вертикальной оси шины, позволяет получить развитую в сторону пшны и обода поверхность замочной части бортозамочного устройства и, тем самым, расширить зону кон- такта шины с замочной частью, т.е. обеспечить не касание шины, а ее прилега- ние к определенной площади поверхности замочной части бортозамочного устройства, что способствует надежному контакту замочной части бортозамоч- ного устройства с ободом, препятствует самопроизвольному выходу бортоза- мочного устройства из зацепления при больших нагрузках, снижению риска раз- герметизации колеса при больших нагрузках и давлении в шине, а значит, спо- собствует надежной эксплуатации колеса. The implementation of the locking part of the locking device with an enlarged cross-section along the horizontal axis of rotation of the wheel in the direction of the vertical axis of the tire allows you to get the surface of the locking part of the locking device developed towards the side of millet and rim, and thereby expand the contact area of the tire with the locking part, t .e. ensure that the tire does not touch, but its adjoining attaching to a certain surface area of the locking part of the locking device with the rim, preventing the locking part of the locking system from engaging under heavy loads, reducing the risk of wheel sealing at high loads and tire pressure, and thus contributes to the reliable operation of the wheel.
Выполнение участка контакта шины с замочной частью бортозамочного устройства не менее величины радиуса борта шины в зоне контакта способству- ет надежному контакту замочной части с ободом, препятствует самопроизволь- ному выходу бортозамочного устройства из зацепления при больших нагрузках, снижению риска разгерметизации колеса при больших нагрузках и давлении в шине, а значит, способствует надежной эксплуатации колеса. При меньшем раз- мере участка касания отсутствует надежное прилегание шины к замочной части бортозамочного устройства, что увеличивает риск выхода замочной части бортозамочного устройства из зацепления с основанием обода и разгерметиза- ции внутренней полости шины.  The implementation of the contact area of the tire with the locking part of the locking system of the tire is not less than the radius of the bead of the tire in the contact zone promotes reliable contact of the locking part with the rim, prevents spontaneous release of the locking system of the engagement under heavy loads, reducing the risk of depressurization of the wheel under heavy loads and pressure in the tire, which means contributes to the reliable operation of the wheel. With a smaller size of the contact area, there is no reliable fit of the tire to the locking part of the locking device, which increases the risk of the locking part of the locking device from engaging with the rim base and depressurization of the inner cavity of the tire.
В результате проведенных патентных исследований не выявлено аналогич- ных технических решений, характеризуемых заявляемой совокупностью при- знаков, что позволяет сделать вывод, что заявляемое техническое решение обла- дают «новизной», может найти применение в промьппленности, т.е. является «промышленно применимым».  As a result of the patent research, no similar technical solutions have been identified, characterized by the claimed combination of features, which allows us to conclude that the claimed technical solution has “novelty”, can be used in industry, i.e. is “industrially applicable”.
Сущность полезной модели поясняется чертежами, где на фиг. 1 изображено колесо транспортного средства с шиной (разрез вдоль оси вращения колеса), на фиг. 2 показана шина (разрез вдоль оси вращения колеса), на фиг. 3 изображена зона контакта шины с замочной частью бортозамочного устройства.  The essence of the utility model is illustrated by drawings, where in FIG. 1 shows a vehicle wheel with a tire (section along the axis of rotation of the wheel), FIG. 2 shows a tire (section along the axis of rotation of the wheel), FIG. 3 shows the contact zone of the tire with the locking part of the flight lock device.
Колесо транспортного средства для бескамерных шин (фиг.1-3) содержит основание обода 1, на котором выполнены посадочные полки 2 и 3, шину 4, бортозамочное устройство, диск 7, вентиль 8.  The vehicle wheel for tubeless tires (Figs. 1-3) contains a rim base 1 on which landing flanges 2 and 3 are made, a tire 4, a locking device, a disk 7, a valve 8.
Бортозамочное устройство включает, согласно примеру конкретного выпол- нения колеса, представленному на фиг.1, бортовое кольцо 5, замочное кольцо 6. Однако заявитель не ограничивает данным примером конкретного выполнения конструкцию применяемого боротозамочного устройства, поскольку оно может быть выполнено также, например, в виде единой детали. The lock-lock device includes, according to an example of a particular embodiment of the wheel shown in FIG. 1, a side ring 5, a lock ring 6. However, the applicant does not limit this example to a specific embodiment the design of the used boro-locking device, since it can also be made, for example, in the form of a single part.
Шина 4 (фиг.2) имеет посадочные поверхности 9, 10, а основание обода 1 - монтажный ручей 11 (фиг.1). Замочное кольцо 6 бортозамочного устройства вы- полнено с посадочными поверхностями для бортового кольца 5 бортозамочного устройства и борта шины 4, при этом сечение профиля замочного кольца 6 уве- личено вдоль горизонтальной оси вращения колеса в направлении вертикальной оси шины 4, а ширина участка контакта шины 4 с замочным кольцом 6 составля- ет не менее величины радиуса R борта шины в зоне контакта.  The tire 4 (figure 2) has a seating surface 9, 10, and the base of the rim 1 - mounting stream 11 (figure 1). The locking ring 6 of the locking device is made with the seating surfaces for the side ring 5 of the locking device and the bead 4, while the cross section of the profile of the locking ring 6 is increased along the horizontal axis of rotation of the wheel in the direction of the vertical axis of the tire 4, and the width of the contact section of the tire 4 with a locking ring 6 is not less than the radius R of the bead in the contact zone.
В качестве примеров используемых шин с определенными радиусами можно привести марки таких шин, как, например, Бел-95 с радиусом борта шины R=3 мм или 600/75R27 Нижнекамскшина с радиусом R=8 мм.  As examples of used tires with certain radii, one can cite brands of tires such as, for example, Bel-95 with a tire radius of R = 3 mm or 600 / 75R27 Nizhnekamskshina with a radius of R = 8 mm.
В частных случая вьшолнения в зависимости от ширины используемой ши- ны максимальный диаметр посадочных полок 2 и 3, имеющих тороидальную форму, может смещаться к вертикальной оси симметрии шины или к бортам.  In particular cases of implementation, depending on the width of the tire used, the maximum diameter of the landing shelves 2 and 3, having a toroidal shape, can be shifted to the vertical axis of symmetry of the tire or to the sides.
В качестве бортовой опоры 12 шины может использоваться как еще одно бортовое кольцо, как это показано в примере конкретного вьшолнения колеса на фиг.1, так и опора, выполненная в виде единой конструкции с ободом 1.  As the side support 12 of the tire can be used as another side ring, as shown in the example of a specific embodiment of the wheel in figure 1, and the support, made in the form of a single design with a rim 1.
В случае наличия в конструкции двух бортовых колец 5 и 12, как это пока- зано на фиг.1 , колесо собирается следующим образом.  If there are two side rings 5 and 12 in the structure, as shown in FIG. 1, the wheel is assembled as follows.
На основание обода 1 устанавливают вентиль 8, устанавливают первое бор- товое кольцо 12, производят монтаж шины 4, устанавливают второе бортовое кольцо 5, а затем замочное кольцо 6 бортозамочного устройства.  A valve 8 is installed on the base of the rim 1, the first side ring 12 is installed, the tire 4 is mounted, the second side ring 5 is installed, and then the lock ring 6 of the lock device.
В процессе эксплуатации шина 4 надежно фиксирует замочное кольцо 6 в основании обода 1, исключая его самопроизвольный выход из зацепления за счет увеличенной поверхности контакта шины 4 с замочным кольцом 6.  During operation, the tire 4 reliably fixes the locking ring 6 at the base of the rim 1, excluding its spontaneous disengagement due to the increased contact surface of the tire 4 with the locking ring 6.
Посадочные полки 2 и 3, имеющие тороидальную форму с обеих сторон ос- нования обода 1, позволяют обеспечить надежность закрепления и герметиза- цию шины 4 на ободе колеса при низком давлении в ее внутренней полости.  Landing shelves 2 and 3, having a toroidal shape on both sides of the base of the rim 1, can ensure reliable fastening and sealing of the tire 4 on the wheel rim at low pressure in its inner cavity.
Таким образом, заявляемое колесо транспортного средства позволяет обес- печить надежность крепления шины на ободе колеса и надежную герметизацию ее внутренней полости, что способствует повышению надежности эксплуатации колеса. Thus, the inventive wheel of the vehicle allows for reliable mounting of the tire on the wheel rim and reliable sealing its internal cavity, which improves the reliability of the wheel.
