Descrição geral General description

O presente pedido diz respeito a um guia de corrente. Este guia de corrente é aplicável a diferentes modelos de motociclos, dada a conjugação dos vários pontos de fixação, apresentando características técnicas de elasticidade, rigidez e resistência à abrasão devido à combinação dos materiais utilizados.  The present application concerns a chain guide. This chain guide is applicable to different motorcycle models, given the combination of the various attachment points, presenting technical characteristics of elasticity, stiffness and abrasion resistance due to the combination of materials used.

O guia de corrente compreende duas peças poliméricas, um corpo exterior e um corpo interior, que encaixam entre si, com características e funções distintas. The chain guide comprises two interlocking polymeric parts, an outer body and an inner body, with distinct characteristics and functions.

O corpo exterior é comum a todos os modelos de motociclos e garante a resistência mecânica do conjunto quando sujeito às condições extremas de utilização, nomeadamente a resistência ao impacto e (in) flexão do guia de corrente. A lateral exterior do corpo exterior é constituído por diversos furos, em número suficiente, para o encaixe dos elementos de fixação que ficam à face da peça polimérica. É possível, mediante o modelo de motociclo em que o guia de corrente está a ser aplicado, utilizar apenas os furos correspondentes aos pontos de fixação do motociclo. The outer body is common to all motorcycle models and ensures the mechanical strength of the set when subjected to the extreme conditions of use, namely the impact resistance and (in) bending of the chain guide. The outer side of the outer body is comprised of several holes, sufficient in number, to engage the fasteners which are to the face of the polymeric part. It is possible, using the motorcycle model to which the chain guide is being applied, to use only the holes corresponding to the motorcycle attachment points.

A base do corpo exterior compreende um mecanismo que permite um encaixe fácil e eficaz aos esforços quando for fixa ao corpo interior. Existe ainda uma pequena nervura cu a função será de garantir o posicionamento correto do corpo interior, em caso de flexão do conjunto, garantindo que as duas peças dão resposta mecânica em conjunto. The base of the outer body comprises a mechanism that allows for easy and effective engagement with stresses when attached to the inner body. There is also a small rib whose function will be to ensure the correct positioning of the inner body, in case of flexion of the set, ensuring that the two pieces give mechanical response together.

O corpo interior, que pode variar em função do modelo de motociclo, em especial no que diz respeito aos pontos de ancoragem no motociclo, estará em contacto com a corrente em funcionamento, pelo que deverá apresentar excelentes características à abrasão e reação a agentes químicos, como lubrificantes ou óleos. O corpo interior compreende duas nervuras longitudinais no interior da peça: uma superior e outra inferior, cuja função, será melhorar o alinhamento da corrente . The inner body, which may vary depending on the motorcycle model, in particular with regard to the anchor points on the motorcycle, will be in contact with the operating chain and should therefore have excellent abrasion and chemical reaction characteristics, as lubricants or oils. The inner body comprises two longitudinal ribs within the piece: one upper and one lower, the function of which is to improve the alignment of the chain.

Todos os corpos interiores formam a aba interior que compreende os pontos de fixação interiores adequados a cada modelo de motociclo, e que limita o movimento de translação e de rotação entre os dois corpos. Neste mesmo ponto são fixos os elementos de fixação, por exemplo casquilhos, que ficam à face do produto. Assim, a base do corpo interior compreende sempre um perfil em forma de C que irá receber a aba que faz parte da peça do corpo exterior. Do encaixe da aba no perfil em C através de deslizamento é obtido o guia de corrente com um encaixe fácil e eficaz ao corpo exterior . Há ainda um pequeno entalhe cu a função será "abraçar" a nervura do corpo exterior de forma a garantir que em caso de flexão do conjunto, as duas peças dão resposta mecânica em conjunto. É possível aplicar o guia de corrente no motociclo sem ser necessário abrir a corrente, graças ao sistema de gaveta nas duas peças. All interior bodies form the inner flange comprising the interior attachment points suitable for each motorcycle model and limiting the translational and rotational movement between the two bodies. At this same point, the fasteners, for example bushes, are fixed to the face of the product. Thus, the base of the inner body always comprises a C-shaped profile which will receive the flap that is part of the outer body part. By sliding the tab into the C-profile by sliding the chain guide is obtained with an easy and effective fit to the outer body. There is still a small notch cu the function will be to "hug" the rib of the outer body to ensure that in case of flexion of the set, the two pieces give mechanical response together. The chain guide can be fitted to the motorcycle without opening the chain thanks to the two-piece drawer system.

O corpo interior do guia de corrente pode ser elaborado, numa forma de realização, em poliamida com média resistência ao impacto e elevada resistência ao desgaste ou poliuretano termoplástico. Quanto ao corpo exterior do guia de corrente pode ser elaborado numa poliamida de elevada resistência ao impacto. The inner body of the chain guide may be made in one embodiment of polyamide with medium impact resistance and high wear resistance or thermoplastic polyurethane. The outer body of the chain guide can be made of a high impact resistance polyamide.
