Patent number: 7942482Abstract: What is disclosed is a brake system for a mobile machine, e.g., for a wheel loader, comprising two hydraulic circuits to each of which at least one respective wheel brake cylinder is associated. Control of the wheel brake cylinders is effected through a brake valve arrangement which, in accordance with the invention, is formed by two brake valves each realized with a hydraulic pilot control, wherein the braking pressure at the one brake valve is reported via a control line into a pilot control chamber of the other brake valve.Type: GrantFiled: February 27, 2004Date of Patent: May 17, 2011Assignee: Bosch Rexroth AGInventor: Hubertus Mies

Publication number: 20100187900Abstract: The invention relates to a hydraulic power brake system comprising a manually operated brake valve (4) via which a pressure medium connection between a brake line (BR1, BR2) and a storage circuit (S1, S2) or a reservoir (T; 70) can be controlled to open. A pilot-controlled, continuously adjustable directional valve (16-22) is provided in the pressure medium flow path between a wheel brake cylinder (26-32) and the brake valve (4), said directional valve being controllable via two pilot valves (86, 90).Type: ApplicationFiled: September 30, 2008Publication date: July 29, 2010Applicant: ROBERT BOSCH GHBHInventors: Andreas Remmelmann, Hubertus Mies, Arne Weidemann, Dietmar Seubert

Patent number: 7377599Abstract: A brake system for a mobile work tool, such as for a logging machine or a combined dredger-loader, is disclosed. The mobile work tool is provided with two non-muscular brake valves for brake actuation which may be operated by the driver in accordance with the orientation in the driver's cab—for instance during road travel and when the driver's direction of view is to the rear. In accordance with the invention, a tank port of a non-muscular brake valve is connected with the brake port of the second non-muscular brake valve, so that the first non-muscular brake valve is connected via the tank port of the second non-muscular brake valve with the pressure medium tank, and upon actuation of the second non-muscular brake valve the generated braking pressure is supplied via the tank port of the first non-muscular brake valve into the latter, so that the brake ports thereof are correspondingly subjected to braking pressure.Type: GrantFiled: January 27, 2003Date of Patent: May 27, 2008Assignee: Bosch Rexroth AGInventor: Hubertus Mies

Patent number: 6209966Abstract: An invention relates to an electrically controlled braking system which is intended for use on a wheeled vehicle and has input means which can be actuated by a driver of the vehicle in accordance with the desired braking effect, two electronic control units, which operate independently of each other and each of which can be supplied with an electrical signal corresponding to the extent of actuation of the input means, which can be recorded by a sensor, a brake cylinder assigned to a wheel and a braking pressure modulator valve which is fluid-connected to the brake cylinder and has a first electric actuating element, which can be activated by a first of the two control units. To make the braking system very safe, the braking pressure modulator valve has a second electric actuating element which acts in the same direction when activated, as the first electric actuating element.Type: GrantFiled: August 31, 1999Date of Patent: April 3, 2001Assignee: Mannesmann Rexroth AGInventor: Hubertus Mies

Patent number: 6038858Abstract: What is disclosed is an inching and braking system for a hydraulically powered apparatus with a brake system and a drive system, wherein the drive system and the brake system can be controlled in order to generate a braking effect by actuating the inching and braking system. In the solution according to the invention, an inching valve arrangement and a brake valve arrangement can be coupled mechanically to one another so that the apparatus can be controlled more sensitively during transition from inching to braking.Type: GrantFiled: April 16, 1998Date of Patent: March 21, 2000Assignee: Mannesmann Rexroth AGInventor: Hubertus Mies

Patent number: 6000219Abstract: A load valve apparatus having a control valve which can be connected to a pump and an accumulator and which in a first position connects the pump to the accumulator and in a second position isolates the pump from the accumulator, and the pump and the accumulator are isolated from one another when the accumulator pressure exceeds a certain value, and a connected consuming device is isolated from the accumulator in such a way that the load pressure of the consuming device does not affect the accumulator. The pressure of the pump and/or of the accumulator is used to regulate the pump.Type: GrantFiled: March 3, 1998Date of Patent: December 14, 1999Assignee: Mannessmann Rexroth GmbHInventor: Hubertus Mies
