  • Patent number: 11215088
    Abstract: A preassembled module for a variable-lift valve drive of an internal combustion engine is provided for installation into a cylinder head. The module has a base plate with an electric linear actuator which lies on an upper side of the base plate. A guide plate, which lies on the upper side, has an outer side wall arranged to guide a slide piece. The guide piece extends below the base plate two downwardly pointing actuating fingers. Each respective actuating finger has a contact surface for moving a transverse coupling slide of a switchable rocker arm. The slide piece has a bracket which protrudes over the guide plate with a contact landing arm which runs transversely relative to the electric linear actuator. An actuator-side end of the contact landing arm is in contact with an actuating pin of the electric linear actuator to move the slide piece.

  • Patent number: 10781757
    Abstract: A variable valve drive of an internal combustion engine is provided that includes at least one gas exchange valve, the valve stroke of said gas exchange valve predefined by cams of a camshaft, and by at least one switchable rocker arm. The switchable rocker arm, having a first lever and a second lever, selectively transmits cam lift to the gas exchange valve. The second lever is selectively coupled to the first lever by a coupling. The coupling is activatable by an elongated activation arm on which one leaf spring is disposed for the coupling of the switchable rocker arm. The elongated activation arm is longitudinally displaceable from a locking position to an unlocking position by a linear actuator. A damper mass is disposed or configured to be capable of oscillating on the elongated activation arm and/or on the leaf spring of the elongated activation arm.

  • Patent number: 10260380
    Abstract: The invention relates to a locking device for a switchable valve drive component, including a first locking body and a second locking body which can be brought into engagement with one another or out of engagement in order to couple to one another or to uncouple two component parts arranged movably with respect to one another, wherein at least one of the two locking bodies has at least one curved surface. In order to increase the wear resistance of the locking device, provision is made for at least one of the two locking bodies to have a plurality of curved surfaces of which the respective curvature is described by radii of identical length having constructional center points spaced apart from one another.

  • Patent number: 8776750
    Abstract: An assembly for a valve train of an internal combustion engine, which has a hydraulic support element and a cam follower resting on one end via a bearing surface located on the bottom side thereof on a complimentary end side of a pressure piston of the support element. The piston extends across the outer shell in a bore of a crucible-shaped housing of the support element. The housing has an opening for hydraulic fluid, which is conductible via a channel between the housing and piston through a passage in the pressure piston to a storage chamber. In a section of a direct contact region between the bearing surface of the cam follower and end side of the piston, an anti-turn mechanism for the piston in relation to the cam follower is implemented. The piston is installed in a defined manner and is torsionally oriented in relation to the cam follower.

  • Patent number: 8689754
    Abstract: An assembly for a valve drive of an internal combustion engine, which has a hydraulic support element and a cam follower connected by way of a clamp. The follower rests on one end via a cap on a spherical head of a pressure piston of the support element. The piston extends in a bore of a housing of the support element. The clamp flanks the cap with holding strips along the sides. The inner sides run in a guide zone on the outer shell of the piston. The housing has an opening for hydraulic fluid that can be conducted between the housing and the piston through at least one passage in the piston to a storage chamber. The guide zone on the piston is also designed as an anti-rotation mechanism therefore. The piston is installed in a defined manner and is torsionally oriented in relation to the cam follower.

  • Patent number: 8635979
    Abstract: A drag lever for actuating a gas exchange valve of an internal combustion engine. The drag lever includes an oblong lever body formed of sheet metal material, wherein the lever body has a bottom and side walls integrally formed at an angle of about 90° onto the bottom on both sides. A first end section of the lever body includes a joint socket formed into the bottom between the side walls. The joint socket serves to pivotally moveably support the drag lever on a joint head mounted stationary in the internal combustion engine. A middle section of the lever body is provided with a cam gripping surface, and a second end section of the lever body has a contact surface extending on the bottom. The contact surface serves for actuating the gas exchange valve. The lever body is dimensioned so as to have essentially the same width in a cross section through the joint socket and in a cross section through the middle section.

  • Patent number: 7444972
    Abstract: A lever for a valve control of a piston engine is provided, which is embodied as a rocker arm, rocker lever or finger lever. A roller (6) is rotationally mounted on a support pin (7) in an intermediate space of the lever. The lateral sides (1, 2) are tapered (8, 9, 10, 16) in a region of a bore (14) which receives the support pin (7), whereby the sum of the widths (12, 13) of the lateral parts (1, 2) is smaller than a total width (11) of the intermediate space (5) enabling a counter perforation of the bore (14) to be possible.
