Publication number: 20140318305Abstract: A fixing device for an adjustable steering column for a motor vehicle includes a first cam carrier having one or more cams fixedly attached thereto, and at least one further cam carrier having one or more cams fixedly attached thereto. The cam carriers are arranged such as to be rotatable relative to each other about a rotational axis. Upon rotation of the cam carriers relative to each other about the rotational axis, the cam or cams of the first cam carrier interact with the cam or cams of the further cam carrier such as to slide exclusively along each other. The fixing device includes at least one energy-consuming damping device which damps the rotation of the cam carrier in at least one direction of rotation about the rotational axis.Type: ApplicationFiled: May 23, 2012Publication date: October 30, 2014Inventors: Konstantin Cron, Simon Blaettler, Hieronymus Schnitzer, Martin Rohr

Publication number: 20140238184Abstract: The invention relates to a camshaft, especially for motor vehicle engines, comprising a hollow outer shaft (1) and an inner shaft (2) arranged coaxially in the outer shaft (1) and mounted in such a way that it can rotate in relation to the outer shaft (1). Said camshaft also comprises first cams (3a) arranged on the outer shaft (1) in a rotationally fixed manner, and second cams (3b) that are arranged on the outer shaft (1) and fixed to the inner shaft (2). According to the invention, a supporting element (7) is provided on at least one of the end regions of the inner shaft (2), said supporting element projecting past the outer shaft (1) in the radial direction. An outer peripheral surface (8) of the outer shaft (1) and an associated inwardly facing surface (9) of the supporting element (7) form a radial bearing.Type: ApplicationFiled: August 16, 2012Publication date: August 28, 2014Inventors: Michael Kunz, Bernd Mann, Markus Melzer, Juergen Meusel

Publication number: 20140225381Abstract: The present invention includes door locks having a cam having three lobes, and to systems including such door locks. The outer lobes of the cam can limit the rotation of the cam. By limiting the rotation of the cam, the outer lobes can ensure that the cam is always ready for immediate activation. The outer lobes can also strike against outer pins of a locking mechanism to cause the cam to rotate with the locking mechanism when the locking mechanism is activated from the opposite side of the locking mechanism. The present invention also extends to methods of installing and using a door lock including three lobes.Type: ApplicationFiled: July 5, 2012Publication date: August 14, 2014Applicant: DIRTT ENVIRONMENTAL SOLUTIONS, LTD.Inventors: Geoff Gosling, Mogens F.

Publication number: 20140165775Abstract: An apparatus that improves rotation of a shaft. The shaft has a cyclical cogging torque acting thereon in a first direction. A support member is adjacent the shaft. The shaft is operable to rotate relative to the support member. A first anti-cogging member is coupled to the support member. A second anti-cogging member is coupled to the shaft to rotate based on rotation of the shaft. A cam surface has a lobe that is included on one of the first and second anti-cogging members. An abutment member is coupled to the other of the first and second anti-cogging members. The abutment member is operable to abut against the cam surface to provide an anti-cogging torque to the shaft in a second direction that opposes the first direction to at least partially offset the cogging torque. The biasing member biases the abutment member toward the cam surface.Type: ApplicationFiled: February 19, 2014Publication date: June 19, 2014Inventor: Raymond Towne
