Patent number: 11511719Abstract: An axle valve module of a compressed air brake system includes a relay valve with a control pressure input connected to a control pressure line which can be connected via a changeover valve alternately to a brake pressure line conducting an introduced brake pressure or to a reservoir pressure line conducting a reservoir pressure. ABS inlet and outlet valves are each formed as a pressure-controlled diaphragm valve with assigned pilot valve, wherein the pilot valves are configured as cyclically controllable 3/2-way magnetic switching valves, A shut-off valve is arranged in the control pressure line of the relay valve, between the changeover valve and the control pressure input of the relay valve or the branch point of a control pressure line of the ABS valves, via which shut-off valve the control pressure present at the control pressure input of the relay valve can be locked in as required.Type: GrantFiled: September 3, 2018Date of Patent: November 29, 2022Assignee: WABCO GmbHInventors: Rafal Bialon, Robert Otremba, Detlef Schmidt

Patent number: 7870780Abstract: A method for identifying low-pressure tires includes determining the number of revolutions of each wheel over a preselected driving distance, and comparing crosswise by summing the number of revolutions of the diagonally opposite front right/rear left and front left/rear right wheels and taking the difference between the sums, a diagonal containing a low-pressure tire being identifiable via the sign of the difference between the diagonals. A further comparison for each side of the vehicle is effected by summing the revolutions of the front left/rear left side and front right/rear right side wheels and comparing the difference between the sums, the side containing a low-pressure tire being identifiable via the sign of the difference between the sides. The difference between diagonals is compared with a low-pressure threshold value. If the threshold is exceeded, the signs of the difference between diagonals and between sides are logically combined to identify the low-pressure tire.Type: GrantFiled: December 15, 2008Date of Patent: January 18, 2011Assignee: WABCO GmbHInventors: Andre Bork, Tobias Munko, Detlef Schmidt

Patent number: 7786633Abstract: An electric motor (100) for controlling the lateral displacement of a shaft (114) connected to a rotor (104) of the electric motor (100) is provided. The electric motor (100) includes one or more stator conductors (106) for carrying a current and one or more permanent magnets (108) to produce a magnetic field (504). The one or more stator conductors (106) interact with the magnetic field (504) when the power is applied, to purposely generate a force with an axial (Fa) and a circumferential component (Fc). The electric motor (100) includes the shaft (114) that travels along a rotor axis (506) in an axial direction when the power is applied, under an action of the axial component of the force. However, when the power is removed, the shaft (114) retracts under the action of a biasing force from a tension device (118).Type: GrantFiled: December 14, 2007Date of Patent: August 31, 2010Assignee: Motorola, Inc.Inventors: Martin R.

Publication number: 20050001709Abstract: An inductive device (200) that includes a core (210) configured so as to be a closed loop and at least one coil (220) around the core, and methods for assembly. The coil is formed from a material having a cross-section with an aspect ratio of a first dimension to a second adjacent dimension, with the first dimension being longer than the second dimension, wherein the coil is positioned around the core such that the first dimension is essentially normal to the core. In one embodiment the core includes a removable core section to enable assembly of the inductive device by slidably placing the coil onto the core through an opening formed in the core by removing the core section. In another embodiment, the coil is rotated to cause it to wind around the core.Type: ApplicationFiled: July 3, 2003Publication date: January 6, 2005Inventors: Martin Pais, James Booth, David Moore, Detlef Schmidt
