SUSPENSION LEG FOR MACHINES MOVING OUTSIDE ROADS
Abstract
Abstract Translated from French Une jambe de suspension hydraulique, renfermant un liquide compressible, comprend un piston percé de canaux et mobile alternativement dans un cylindre de manière à en diviser la chambre en deux parties. Les canaux du piston assurent une circulation réglée du liquide de l'une des parties de la chambre dans l'autre. Un élément de clapet s'applique contre le piston lorsque la jambe de suspension est mise en position d'extension sous l'effet d'un rebondissement, de manière à réduire considérablement la circulation du liquide à travers le piston et à amplifier l'amortissement au moment d'un rebondissement. Cet élément de clapet est soumis à la force de deux ressorts qui le retiennent l'écart du piston en fonctionnement normal, mais lui permettent de se rapprocher du piston au cours d'un rebondissement. Application aux engins lourds de transport pour chantiers de construction. A hydraulic suspension strut, containing a compressible liquid, comprises a piston pierced with channels and movable alternately in a cylinder so as to divide the chamber into two parts. The channels of the piston ensure controlled circulation of the liquid from one part of the chamber to the other. A valve member is applied against the piston when the suspension strut is rebounded into the extended position, thereby significantly reducing the flow of liquid through the piston and enhancing damping at the time of a bounce. This valve member is subjected to the force of two springs which keep it away from the piston during normal operation, but allow it to move closer to the piston during a rebound. Application to heavy transport vehicles for construction sites.
