Title (EN) BRAKE DEVICE FOR A CONSTRUCTION MACHINE
(FR) DISPOSITIF DE FREINS DESTINÉ À UNE MACHINE DE CONSTRUCTION
Abstract: front page image
(EN)The invention relates to a brake device (1) for a construction machine, comprising a first brake circuit (2), which is coupled to a first brake member (4) on a first wheel axle (6) of the machine, a second brake circuit (8), which is coupled to a second brake member (10) on a second wheel axle (12) of the machine, the first and second brake circuits (2, 8) being independent of one another, a pressure source (14) for hydraulic oil, which is coupled to the first and second brake circuit (2, 8), and a brake valve (16, 16'), which is coupled to the first and second brake circuit (2, 8), which brake valve (16, 16') is designed to control the hydraulic oil from the pressure source (14) to the brake members (4, 10) on the wheel axles (6, 12). The first or second brake circuit (2, 8) comprises limiting elements (18, 42'), which limit the pressure and/or flow of hydraulic oil when the brake valve (16, 16') controls the hydraulic oil from the pressure source (14) to the brake members (4, 10) on the wheel axles (6, 12).
(FR)L'invention concerne un dispositif de freins (1) destiné à une machine de construction, qui comporte un premier circuit de freins (2) couplé à un premier élément de freins (4) situé sur un premier essieu de roue (6) de la machine, un second circuit de freins (8) couplé à un second élément de freins (10) situé sur un second essieu de roue (12) de la machine, le premier et le second circuit de freins (2, 8) étant indépendants l'un de l'autre, une source de pression (14) d'huile hydraulique, couplée au premier et au second circuit de freins (2, 8) et un clapet de frein (16, 16') couplé au premier et au second circuit de freins (2, 8), ce clapet étant conçu pour commander l'huile hydraulique de la source de pression (14) aux éléments de freins (4, 10) sur les essieux de roue (6, 12). Le premier ou le second circuit de freins (2, 8) comprend des éléments de limitation (18, 42'), qui limitent la pression et/ou le débit d'huile hydraulique lorsque le clapet de frein (16, 16') commande l'huile hydraulique de la source de pression (14) aux éléments de freins (4, 10) situés sur les essieux de roue (6, 12).
