Abstract

The axle of wheel 5 is mounted in a bearing of sleeve 3 which is coupled to the frame member 6 of the bogie by rubber springs 2. Between the sleeve 3 and the element 8, which is attached to frame member 6 and contains the spring 2, a removable guiding body 1 is fitted. By varying the thickness of the body 1 and hence the longitudinal and/or transverse clearance, the response of the primary suspension in the horizontal plane is varied in frequency and amplitude, enabling the optimum conditions for smooth running to be achieved empirically. <IMAGE>

E sabido qus um dos problemas mais importantes, nos \je_i culos ferroviários, é o de melhorar o mais possível a qualidade da marcha.It is known that one of the most important problems in railway vehicles is to improve the quality of the journey as much as possible.

método comumnente adoptado para conseguir esse resul tado é o de praticar uma boa conservação da via e construir bcgies com suspensões primárias e secundárias de características adequadas.The common method adopted to achieve this result is to practice good road maintenance and build bcgies with primary and secondary suspensions of suitable characteristics.

Apesar da adopção destas precauções de qualidade de cori servação e de projecto, o nível da qualidade da marcha, especialmente em vias de classe mãis baixa, não resulta sempre satisfatório e sobretudo só pode ser raramente melhorado, mesmo quan do as suspensões sejam providas de dispositivos e/ou sistemas intrínsecos e/ou adicionais muito complicados. Estes dispositi vos ou sistemas são, no entanto, dispendiosos e nem sempre sequ ros.Despite the adoption of these precautions for the quality of maintenance and design, the level of gait quality, especially on lower class tracks, is not always satisfactory and above all it can only be rarely improved, even when suspensions are provided with devices and / or very complicated intrinsic and / or additional systems. These devices or systems are, however, expensive and not always sequential.

objectivo do presente invento consiste na realização de um dispositivo de guiamento anti-desgaste para suspensões primárias de bogies para veículos ferroviários que seja de concepção e aplicação simples e que se possa instalar directarnente entre os carris da via, ponto de origem de todas as perturbações e a suspensão primária do bogie, de forma a melhorar a qua lidade da marcha do veículo ferroviário.The objective of the present invention is to create an anti-wear guiding device for primary bogie suspensions for railway vehicles that is simple to design and apply and that can be installed directly between the track rails, the point of origin of all disturbances and the primary suspension of the bogie, in order to improve the gait quality of the railway vehicle.

Este objectivo atings-se, em conformidade com o invento, por meio de um dispositivo de guiamento anti-desgaste para suspensões primárias de bogies para veículos ferroviários com um brinco de suporte para cada roda, em que o brinco esteja ligado ao chassis por meio da suspensão primária, caracterizado pelo facto de compreender entre o referido brinco e uma parte solidá ria com o chassis do bogie, pelo menos, um corpo de guiamento, montado de forma amovível, de maneira a deixar folgas longitudi.This objective is achieved, in accordance with the invention, by means of an anti-wear guiding device for primary suspension of bogies for railway vehicles with a support earring for each wheel, in which the earring is connected to the chassis by means of the primary suspension, characterized by the fact that it comprises between said earring and a part integral with the bogie chassis, at least one guide body, removably mounted, in order to leave longitudinal gaps.

nais e transversais entre o brinco e a referida parts.between the earring and the said parts.

Um dispositivo, em conformidade com o invente, aumenta, no plano horizontal, o valor do facto? de amortecimento e, portanto, o nível da qualidade de marcha de modo bastante eficaz, visto que actua directamente na fonte das perturbações em vez de agir sobre a aceleração; muito mais fatigante para os passa geiros.Does a device, in accordance with the invention, increase, in the horizontal plane, the value of the fact? of damping and, therefore, the level of gait quality quite effectively, since it acts directly at the source of the disturbances instead of acting on the acceleration; much more stressful for passengers.

Ao mesmo tempo, um dispositivo em conformidade com o in vento, permite obter uma qualidade de marcha óptima por intermé dio de modificações de optimização, adequadas, sucessivas e fáceis. Estas podem ser efectuadas, com vantagem, em bogies protótipo, sem ter de suspender a produção em série, medindo as acelerações no plano horizontal durante as experiências no local e, portanto, em função das reais características da via.At the same time, an in-wind compliant device provides optimum running quality through appropriate, successive and easy optimization changes. These can be carried out, advantageously, in prototype bogies, without having to suspend series production, measuring the accelerations in the horizontal plane during on-site experiments and, therefore, according to the actual characteristics of the track.
