Abstract

"AMORTECEDOR HIDRáULICO VEICULAR". Amortecedor hidráulico veicular, particularmente aplicável à suspensão traseira de veículos automotores, compreendendo um corpo tubular (10), preenchido com um fluido viscoso (FV) em material flexível e impermeável, tendo uma primeira e uma segunda parede extrema (11,12) axial e relativamente deslocáveis entre si; um primeiro meio de suporte (30) montado a uma das massas suspensa e não-suspensa do veículo e contra o qual é fixada a primeira parede extrema (11) do corpo tubular (10); um reservatório (40) cilíndrico, rígido, hermético, contendo gás a alta pressão, tendo uma parede extrema externa (41) fixada à outra de ditas massas suspensa e não-suspensa e uma parede extrema interna (42) oposta à primeira e constituindo um segundo meio de suporte (50) contra o qual é fixada a segunda parede extrema (12) do corpo tubular (10); e meios de válvula (60) providos na parede extrema interna (42) do reservatório (40), de modo a estabelecerem comunicação fluida seletiva e restrita entre o corpo tubular (10) e o reservatório (40) durante a movimentação da suspensão do veículo."VEHICLE HYDRAULIC SHOCK ABSORBER". Vehicle hydraulic shock absorber, particularly applicable to the rear suspension of motor vehicles, comprising a tubular body (10), filled with a viscous fluid (PV) in flexible and impermeable material, having a first and a second extreme wall (11,12) axial and relatively movable with each other; a first support means (30) mounted to one of the suspended and unsuspended masses of the vehicle and against which the first extreme wall (11) of the tubular body (10) is attached; a cylindrical, rigid, airtight reservoir (40), containing high pressure gas, having an outer extreme wall (41) attached to the other of said suspended and non-suspended masses and an inner inner wall (42) opposite the first and constituting a second support means (50) against which the second extreme wall (12) of the tubular body (10) is fixed; and valve means (60) provided in the extreme inner wall (42) of the reservoir (40), in order to establish selective and restricted fluid communication between the tubular body (10) and the reservoir (40) during the movement of the vehicle suspension .
