Patent number: 6453936Abstract: A valve system for the pre-engagement unit of a vehicle braking pressure modulator contains solenoid valves, which are controlled by an electronic braking system. Pneumatic pressure is fed into a brake cylinder on the vehicle wheels via a pressure regulating channel of the pre-engagement unit. The solenoid valves are configured as cartridge solenoid valves, so that assembly is simplified, and utilization of elastic tolerance compensating elements is unnecessary. A preferred embodiment includes three cylinder bodies connected end-to-end with no increase in cylinder diameter. This embodiment enables the use of identical armatures and identical magnet coils for different valve types, such as 3/2-way solenoid valves or 2/2-way solenoid valves. Also, these valves may be configured as normally open or normally closed, with identical outside dimensions. As such, three cartridge solenoid valves can be combined into a compact triple valve cartridge unit that further simplifies the assembly process.Type: GrantFiled: February 23, 2001Date of Patent: September 24, 2002Assignee: WABCO GmbH & Co. oHGInventors: Dieter Frank, Gerdt Schreibert, Peter Homann, Armin Sieker, Andreas Kranz, Hans-Klaus Wolff, Dirk Meier

Patent number: 6105931Abstract: A wear-resistant valve, having at least two parts which move relative to each other, and which impact against each other, avoids damage to the contacting parts over long operating periods, with very little additional space requirement, and at low cost. At least one of the impact surfaces is covered with a thin coating. The material used for the coating is plastic, in particular, a fluorine-containing polymer material, such as polytetrafluoroethylene. The valve closing element, whose valve closing surface makes contact with a valve seat when the valve is actuated, is preferably provided with the coating. Valve arrangements which are actuated electromagnetically by a pulsing electrical signal are preferred areas of application for the present invention.Type: GrantFiled: July 9, 1998Date of Patent: August 22, 2000Assignee: WABCO GmbHInventors: Dieter Frank, Sigfried Hofler, Henning Kutzner

Patent number: 5403073Abstract: A process and apparatus for the braking with optimized stability of a vehicle train is disclosed. The vehicle train comprises at least two individual vehicles, one of the individual vehicles supporting the individual vehicle. The process comprises supplying energy to the brakes of the vehicles, thereby actuating the brakes and producing an actual force between the vehicles, and measuring the actual-value horizontal and vertical components (F.sub.hact, F.sub.vact) of the actual force (F.sub.act) acting between the supporting and supported vehicle. A desired-value horizontal force component (F.sub.hdes) of the force is determined by multiplying the actual-value vertical component (F.sub.vact) by the ratio of the actual-value train deceleration (b) to the earth's acceleration (g). The desired-value horizontal force component (F.sub.hdes) is then compared with the actual-value force horizontal component (F.sub.hact). The energy supplied to the brakes is adjusted so that F.sub.Type: GrantFiled: December 17, 1993Date of Patent: April 4, 1995Assignee: WABCO Standard GmbHInventors: Dieter Frank, Hartmut Schappler, Axel Stender, Norbert Witte

Patent number: 4679518Abstract: A forked thill head attachment for installing a forked thill to a sail mast of a rigging comprises a forked thill head (1) which, in a top view, is constructed essentially V-shaped, and opposed clamping jaws for gripping about the mast having a rearward vertical gap (17). In order to produce a firm connection between a forked thill and a mast for a rigging, that can be firmly locked and released with little expenditure of force, the clamping jaws (13) are constructed as a separate component from the forked thill head (1) and held by a longitudinal bolt (21) guided through the forked thill head (1) in the longitudinal direction in the plane of longitudinal symmetry. Locking rotation of the screw member provided at the forward outer side of the forked thill head (1) over the longitudinal bolt (21), moves clamping jaws (13) in the longitudinal direction while contacting, in the forward direction, contacting surfaces (11) likewise running, in a top view, V-shaped to one another.Type: GrantFiled: May 14, 1986Date of Patent: July 14, 1987Inventor: Dieter Frank
