  • Patent number: 10948941
    Abstract: A pedal unit for a motor vehicle may include a multiplicity of cylinder elements which are guided one inside the other in a telescopic fashion along a movement axis, a pedal face for a user, one or more spring elements, and a sensor unit. The pedal face may be coupled to one of the cylinder elements. Each of the spring elements is configured to interact with two cylinder elements assigned thereto, as a result of which, when the pedal face is activated an opposing force can be generated at the pedal face, the opposing force depending progressively on movement travel of the pedal face. The sensor unit may be configured to generate an output signal that is dependent on activation of the pedal face.

  • Patent number: 9850961
    Abstract: The clutch pedal system for a vehicle, such as a motor vehicle, is disclosed. The clutch pedal system includes a pedal carrier having a fastening region configured to be associated with an aperture in a bulkhead and/or a dashboard carrier of the vehicle. A clutch pedal is pivotably mounted on the pedal carrier. A master cylinder is supported on an adapter region of the pedal carrier and is connected to the clutch pedal. The master cylinder is positioned such that at least a portion of the master cylinder extends through the aperture, wherein the pedal carrier is configured to position the master cylinder in a predetermined position relative to the bulkhead and/or of the dashboard carrier.

  • Publication number: 20170351291
    Abstract: A clutch pedal for an electrically operated clutch system simulates the pedal forces of a hydraulically actuated clutch. An operating element is pivotably supported on a mounting so as to move along an operating path between a non-operating position and an operating position. A restoring spring applies a force towards the non-operating position. At least one friction element rubs against a curved friction surface when the operating element is pivoting along the operating path. The friction element is spring-loaded against the friction surface. During operation between the operating position and the non-operating position, the friction element moves over a cam lobe of the friction surface. The friction element is elastically movable radially in relation to the curved friction surface.

  • Patent number: 8511503
    Abstract: A liquid container (1) for holding a liquid (2) of a motor vehicle, having a front wall (4) arranged in the direction of travel of the vehicle and a rear wall (6) opposed thereto and an upper wall (8). To reduce sloshing noises generated by having a wave forming in the liquid container (1) due to acceleration, at least one compensating tube (24) is provided, having a first opening (27), a connecting portion (26) and a second opening (28). The first opening (27) arranged proximate the front wall (4), and the second opening (28) arranged proximate the rear wall (6). The connecting portion (26) fluidly couples the first and second openings (27 and 28).
