摘要:
Es wird ein Getriebe (10), insbesondere Zapfwellengetriebe, mit einem Getriebegehäuse (12), einer im Getriebegehäuse (12) gelagerten Welle (14) und einer im Getriebegehäuse (12) angeordneten Bremse (20) zum Bremsen der Welle (14) vorgeschlagen, wobei die Bremse (20) einen ersten auf der Welle (14) axial verschiebbar gelagerten Ringkolben (22) und einen am Getriebegehäuse (12) befestigten Bremskörper (62) umfasst und wobei der erste Ringkolben (22) axial in Richtung des Bremskörpers (62) gegen diesen vorspannbar und durch axiale Verschiebung entgegen der Vorspannung von diesem lösbar ist. Um dem Verschleiß des Bremskörpers auszugleichen wird vorgeschlagen, dass der Bremskörper (62) axial verschiebbar gelagert ist.
摘要:
The invention concerns a disc brake (2) for motor vehicle, comprising: a calliper (4); linings; an actuator (42) and a piston (20); and linking means (70) for compensating lining wear interposed between the actuator (42) and the piston (20) such that when the actuator slides in a first direction relative to the calliper it causes the piston to slide. The linking means (70) are designed to produce a wedging effect so as to block the piston (20) relative to the actuator (42) when it slides, and to cause the piston to be mobile relative to the actuator in a second direction.
摘要:
A brake pad for friction brakes of the disk brake type is provided with a brake lining (7) mounted on a support means (8), such as to be pressable against a brake disk (2). The support means carries a centrally placed pressure distributor (5) for translating pressing force to the brake pad (3). The support means includes a first (9) and a second (10) part between which a liquid-filled balancing chamber (11) is arranged. Force translation between the first and second parts is intended to take place substantially via the liquid in the balancing chamber (11), so that good surface engagement is enabled between the brake disk (2) and lining (7), also for large pressing force and when the brake pad has large extension.

摘要:
The present inventions provide two methods of controlling brake clearance (410) of a braking system of a vehicle (100) and a method for detecting brake wear, each method including providing a brake actuator (516, 518; 716, 718), a brake input device (520; 720), and a cross-drive transmission (502; 702) having an output (508, 510; 708, 710) and a brake pack (406, 408). These methods include (602,802) receiving a brake input request from the brake input device (520; 720), actuating the brake actuator (516, 518; 716, 718) to apply the brake pack (406, 408), and moving the brake actuator (516, 518; 716, 718) from a first position to a second position during the actuating step. These methods further include (604,606,804,806) detecting an axial movement of the actuator (516, 518; 716, 718) from the first position to the second position, comparing (608,610,808,810) said axial movement to a respective clearance or wear threshold. The first two methods also include adjusting (612,614) a return position of the brake actuator (516, 518) that is offset from the first position when the axial movement exceeds the clearance threshold and controling (612,614) the movement of the brake actuator (516, 518) from the second position to the return position. According to the third method (812) a wear alert message is sent to the vehicle operator if either the first or second axial movement of the brake actuator (716, 718) exceeds its respective wear threshold. Three further inventions for three control systems are provided, each of the control systems performing one of the above methods
摘要:
The invention relates to a hydraulic braking system (1) for braking a moving mass, comprising a pressure element (14) for pressing onto a brake surface (15) under friction, a brake actuator (8) filled with hydraulic fluid for producing pressure in the pressure element (14) and distancing means for adjusting play between the pressure element (14) and the brake surface (15) when the brake system (1) is in the non-active position. The aim of the invention is to provide an economical, light and reliable braking system. The distancing means comprise a hydraulic accumulator (4) for accumulating a predefined volume of hydraulic fluid at a minimum pressure, said hydraulic accumulator (4) can be connected to the brake actuator (8) thus preventing mechanical stopping or blocking means being used.
