  • Patent number: 4286802
    Abstract: A telescopic leg suspension comprising a lower wheel-supporting element connected by an articulated lever to the structure of the vehicle, an upper element articulated to the structure and serving to guide the lower element, these two elements being able to slide and possibly rotate in relation to each other and a device for causing pressurized liquid to act between the elements in such a way that the liquid tends to separate these two elements axially one from the other.One of the two elements comprises a tubular member having at one end a bore and a piston adapted to slide sealingly in this bore, the pressurized liquid being contained in this member whereas the other element comprises a cylinder surrounding the member, this cylinder being closed at one end by a bottom against which the piston bears, guiding between the two elements being provided between the cylinder and the member.This invention applies more particularly to a suspension for a motor vehicle steering wheel.
