Abstract

"TUBO PARA BARRA DE DIREçãO COM DEFORMAçãO CONTROLADA". Trata-se a invenção de um tubo para barra de direção com deformação controlada, para ser utilizada em veículos automotores, nos quais utiliza-se processos de conformação controlada ou localizada, com técnicas de pressão hidráulica (hydroforming) ou prensagem convencional, que produzem nos tubos diversas formas de perfis, tais como, quadrado, sextavado, estrelado, etc..., perfis estes, que são posicionados de modo a aumentar a resistência do tubo no sentido em que o mesmo é mais solicitado, reforçando assim a sua resistência à flexão. Com esta técnica pode-se utilizar tubos com paredes de espessura menor que a dos tubos convencionais utilizados em barras de direção, o que vem atender às exigências de redução de peso dos projetos atuais, sem entretanto, causar qualquer prejuízo à condição de segurança que precisa ter uma barra de direção veicular. A deformação controlada pode ser utilizada em toda a extensão do tubo quando se tratar de uma barra de direção reta, ou pode ser localizada nas curvas do tubo, quando a barra de direção possuir este formato, mas, em qualquer situação, os perfis resultantes desta deformação deverão sempre estar posicionados no sentido em que o tubo ou a curva são mais solicitados, para aumentar sua resistência."CONTROLLED DEFORMATION STEERING BAR TUBE". This is the invention of a controlled deformation steering rod tube for use in automotive vehicles where controlled or localized forming processes are employed, with conventional hydroforming or pressing techniques, which produce in the pipes have various shapes of profiles, such as square, hexagonal, starred, etc ..., these profiles, which are positioned in such a way as to increase the strength of the pipe in the direction in which it is most requested, thus reinforcing its resistance to flexion. With this technique it is possible to use tubes with walls smaller than the conventional tubes used in steering bars, which meets the weight reduction requirements of current designs, without, however, causing any damage to the safety condition that needs have a vehicular steering bar. Controlled deformation can be used to the full extent of the pipe when it is a straight guide bar, or it can be located at the pipe bends when the guide bar has this shape, but in any case the profiles resulting from it Deformation should always be positioned in the direction in which the pipe or bend is most requested to increase its strength.
