Abstract

"SISTEMAS DE SUSPENSãO DE VEìCULO". A invenção se refere aos veículos de estrada e, mais especificamente, a um eixo de suspensão central, destinado à retro-ajuste de um veículo existente. Eixos de suspensão central para retro-ajuste, em virtude de sua construção predominantemente forjada, e sede de mola finamente soldada com uma ranhura de mola usinada, possuem distorções que tomam os mesmos extremamente difíceis de garantir o ajuste fácil da mola à sede, a posição e alinhamento de uma mola e a anexação da mesma ao suspensor frontal no veículo, quando o eixo é ajustado ao veículo. Estas dificuldades conhecidas são evitadas por um eixo de suspensão central compreendendo uma sede de mola (2) localizada em uma respectiva extremidade do eixo de suspensão central (1) tal que, a mola (3) ajustada à sede de mola possui suas extremidades livres em uma posição necessária para que ela seja anexada ao suspensor (8) de um veículo, um dispositivo (7) de aplicação de pressão sobre a sede de mola para ajudar de modo que ela mantenha sua posição necessária em relação ao eixo de suspensão central e um dispositivo para prender a sede de mola ao eixo, e onde na montagem do eixo e suas molas, os parafusos em U são deixados frouxos e os elementos de travamento na sede de mola retraídos, para permitir que a extremidade da mola seja deslizada para baixo da placa de travamento, o eixo sendo então apresentado a um gabarito que impede o movimento do mesmo e permite que a extremidade livre da mola seja colocada na posição necessária para sua anexação subsequente ao suspensor no veículo, para fazer com que a mola assuma uma posição correta na sede, após o que os elementos de travamento são impulsionados em uma direção de contato das laterais da mola e parafusos em U apertados para travar a sede de mola e, conseq³entemente, a mola em posição com relação ao eixo. A invenção também se refere a um suspensor frontal (8) para uma mola em folha (3) de um eixo de suspensão central (1) compreendendo um dispositivo de conexão (8A, 9) ao chassis do veículo e dispositivos (4,16) de conexão articulada da extremidade de uma mola em folha, o dispositivo de conexão da extremidade de uma mola em folha compreendendo um componente semelhante a suporte com paredes laterais (12, 18), as paredes laterais sendo externamente divergentes na direção da extremidade aberta do suporte, pelo que para aceitar a mola (3) e existindo um dispositivo de anexação de um pino de articulação na extremidade livre da mola em relação ao suporte."VEHICLE SUSPENSION SYSTEMS". The invention relates to road vehicles and, more specifically, to a central suspension axle for retrofitting an existing vehicle. Central suspension axles for retrofitting, due to their predominantly forged construction, and finely welded spring seat with a machined spring groove, have distortions that make them extremely difficult to ensure easy adjustment of spring to seat, position and aligning a spring and attaching it to the front suspension in the vehicle when the axle is adjusted to the vehicle. These known difficulties are avoided by a central suspension shaft comprising a spring seat (2) located at a respective end of the central suspension shaft (1) such that the spring (3) fitted to the spring seat has its free ends at each other. a position necessary for it to be attached to a vehicle's hanger (8), a spring seat biasing device (7) to assist it in maintaining its required position relative to the center suspension axle and a device for securing the spring seat to the shaft, and where at the mounting of the shaft and its springs, the U-bolts are left loose and the locking elements on the spring seat retracted to allow the spring end to slide down from the shaft. locking plate, the shaft being then presented to a template which prevents its movement and allows the free end of the spring to be placed in the position necessary for its subsequent attachment to the suspension in the vehicle to make the spring assume a correct seat position, after which the locking elements are driven in a spring-side contacting direction and tight U-bolts to lock the spring seat and therefore , the spring in position with respect to the shaft. The invention also relates to a front suspension (8) for a leaf spring (3) of a central suspension axle (1) comprising a vehicle chassis connecting device (8A, 9) and devices (4,16) of a leaf spring end pivot, the leaf spring end connection device comprising a side-wall support-like component (12, 18), the side walls being externally divergent toward the open end of the support whereby to accept the spring (3) and there is a device for attaching a pivot pin at the free end of the spring with respect to the holder.
