  • Patent number: 11511719
    Abstract: 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.

  • Publication number: 20200331478
    Abstract: A method for controlling a starting process of a vehicle includes activating a control sequence and setting a control sequence signal, defining a maximum engine drive torque, and detecting a drive request for a starting process. The method further includes, in response to the drive request, controlling a clutch-gearbox unit with an engagement process duration, controlling wheel slip of driven wheels by determining wheel speeds of the driven wheels and at least setting an output drive torque at the output shaft, and redefining the maximum engine drive torque depending on the wheel slip and a driving speed. The method also includes deactivating the control sequence and resetting the control sequence signal when limit values are reached.

  • Patent number: 9994667
    Abstract: The invention has as subject matter a method for producing a polyurethane cast resin, wherein the production comprises the steps of mixing at least one thiol component with at least one isocyanate component, degassing of the mixture and hardening of the polyurethane polymer in a one-stage process. Cast resins for electronic or optoelectronic components of for the production of optical lenses are obtained by the method of the invention that have good mechanical properties and very good optical properties at the same time by a suitable combination of polythiols as hardening component with commercially available isocyanates. The addition of special isocyanates is also not very necessary, as is the case for carrying out the method in several stages. The method in accordance with the invention results in an economical, one-stage process in the properties of the cast resin that are necessary for the application range.

  • Patent number: 7870780
    Abstract: 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.

  • Patent number: 7786633
    Abstract: 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).

  • Publication number: 20050001709
    Abstract: 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.
