Abstract

FIELD: machine building.SUBSTANCE: invention relates to machine building, particularly, to connection of connecting rod with bicycle sprockets. Proposed method consists in that rod with turn section is arranged in shaped recess of plastic disc and detached by screws, and in other shaped recesses of plastic disc sprockets are located and unfolded.EFFECT: higher reliability of connection.1 cl, 2 dwg

Description

Данное изобретение относится к транспортным средствам, в частности, к велосипедам, и может быть использовано для велосипедов различного назначения.This invention relates to vehicles, in particular to bicycles, and can be used for bicycles for various purposes.

В настоящее время широко распространено соединение шатуна со звездами велосипеда при помощи запрессовки или винтового соединения с длинными выступами, что исключает возможность использования шатуна без звезд. Для замены одного сломанного шатуна приходится покупать пару, лишний из которых обычно выбрасывается, что экономически нецелесообразно и вредно для экологии.At present, it is widespread to connect the connecting rod to the stars of the bicycle using a press-in or screw connection with long protrusions, which excludes the possibility of using a connecting rod without stars. To replace one broken connecting rod, you have to buy a pair, the extra of which is usually thrown away, which is economically impractical and harmful to the environment.

Известен способ соединения шатуна со звездами велосипеда, описанный в патенте US 2013/0291678 А1 и отличающийся тем, что крепление осуществляется винтами к рычагу шатуна и четырем выступам, объединенным в два сектора. При этом большая звезда специальными упорами дополнительно стопорится о боковую поверхность секторов.There is a known method of connecting the connecting rod with the stars of a bicycle, described in US patent 2013/0291678 A1 and characterized in that the fastening is carried out with screws to the connecting rod arm and four projections combined into two sectors. In this case, the large star additionally stops with special stops on the lateral surface of the sectors.

К недостаткам данного способа относятся:The disadvantages of this method include:

- большой радиус секторов;- large radius of sectors;

- сложность изготовления шатунов и звезд;- the complexity of manufacturing connecting rods and stars;

- малая площадь контакта звезд в местах крепления;- small contact area of the stars in the attachment points;

- невозможность использования шатуна без звезд.- the inability to use a connecting rod without stars.

Целью изобретения является облегчение и упрощение соединяемых деталей, увеличение площади контакта звезд для защиты от деформации, создание возможности использовать шатун по назначению без звезд.The aim of the invention is to facilitate and simplify the parts to be joined, to increase the contact area of the stars to protect against deformation, to make it possible to use the connecting rod for its intended purpose without stars.

Поставленная цель достигается тем, что шатун 1 имеет поворотный элемент 2 малого размера, расположенный в фасонной выборке 3 пластмассового диска 4 и раскрепленный винтами 5. Звезды 6 и 7 расположены в фасонных выборках 8 и 9 диска 4, раскреплены винтами 10 и 11. Возможно раскрепление звезд заклепками, с помощью клея или иным способом.This goal is achieved by the fact that the connecting rod 1 has a small pivot element 2 located in the shaped cutout 3 of the plastic disc 4 and fastened with screws 5. Stars 6 and 7 are located in the shaped cutouts 8 and 9 of the disc 4, fastened with screws 10 and 11. It is possible stars with rivets, glue or otherwise.

Изобретение поясняется рисунком.The invention is illustrated by a drawing.

На фиг. 1 изображен способ соединения шатуна со звездами согласно патента US 2013/0291678 А1.FIG. 1 shows a method for connecting a connecting rod with stars according to US patent 2013/0291678 A1.

На фиг. 2 изображен предлагаемый способ соединения шатуна со звездами винтами.FIG. 2 shows the proposed method of connecting the connecting rod with the stars with screws.

Таким образом, применение пластмассового диска с фасонными выборками для плотного размещения и раскрепления соединяемых деталей облегчает конструкцию, снижает использование металла, уменьшает напряжения в узлах всвязи с большей площадью соприкосновения, позволяет использовать шатун без звезд. Благодаря простоте способ обеспечивает широкое применение, повышает рациональность использования применяемых деталей и сохраняет экологию.Thus, the use of a plastic disc with shaped grooves for tight placement and loosening of the parts to be joined facilitates the design, reduces the use of metal, reduces stresses in the nodes with a larger contact area, and allows the use of a connecting rod without stars. Due to its simplicity, the method provides widespread use, increases the rationality of the used parts and preserves the environment.

Claims (1)

Способ соединения шатуна со звездами велосипеда заключается в том, что шатун, имеющий поворотный участок, располагают в фасонной выборке пластмассового диска и раскрепляют винтами, а в других фасонных выборках пластмассового диска располагают и раскрепляют звезды.The method of connecting the connecting rod with the stars of the bicycle is that the connecting rod, which has a pivoting section, is placed in the shaped sample of the plastic disc and fastened with screws, and the stars are positioned and unfastened in other shaped samples of the plastic disc.
