Patent number: 11193586Abstract: A parking lock for a transmission of a motor vehicle may include a park gear rotatable about an axis of rotation, and an actuation device adjustable into a locking position and an unlocking position radially relative to the axis of rotation. In the unlocking position, rotating of the park gear may be possible, and in the locking position, rotating of the park gear may be prevented by way of positive locking. The actuation device may include a shifting drum and a locking lever, wherein the shifting drum may be rotatable about a guiding axis that is radial relative to the axis of rotation. The locking lever, by way of a guide track formed in the shifting drum, may interact with the guide track so that when the shifting drum is rotated, the locking lever may be guidable by the guide track radially relative to the axis of rotation and parallel to the guiding axis, and thereby the actuation device may be adjustable into the locking position and into the unlocking position.Type: GrantFiled: November 26, 2019Date of Patent: December 7, 2021Inventors: Martin Berger, Karl-Heinz Hanslik, Hermann Hoffmann, Florian Kollitz

Patent number: 8490587Abstract: The present invention relates to a cam drive (1) having a camshaft and having cams (18, 18?)arranged thereon and having at least one rocker arm (3) which has a cam follower (2) and which is operatively connected by means of its first arm (4) to a plunger-like bearing (5) and by means of its second arm (6) to at least one gas exchange valve (7) of an associated cylinder. The cam drive (1) also has a device (10) for varying the lift of the at least one gas exchange valve (7). Here, it is essential to the invention that the device (10) is embodied as a clutch device which acts between the plunger-like abutment (5) and the rocker arm (3, 3?, 3?)and which has an actuating element (12) which is mounted so as to be rotatable about an axis (13) of the plunger-like abutment (5) at least between two positions, wherein a valve lift in a first, coupled position of the actuating element (12) is varied in comparison with a second, decoupled position.Type: GrantFiled: July 4, 2007Date of Patent: July 23, 2013Assignee: Mahle International GmbHInventors: Thomas Hale, Jonathan Hall, Hermann Hoffmann

Patent number: 8327815Abstract: The present invention relates to an adjustable camshaft (1), which is connected to a crankshaft via a sprocket/belt pulley (3) and has a phase adjusting device (4) for adjusting the phase between the camshaft (1) and the crankshaft. The essential idea of the invention is that the phase adjusting device (4) comprises a planetary gear (5) having at least two sun wheels (6 and 7) disposed coaxially to each other and planet wheels (8) surrounding said sun wheels, wherein said planet wheels are rotatably supported on a planet wheel carrier (10) via a planet wheel axis (9). Said planet wheel carrier (10) can be rotated in relation to the camshaft axis (11), wherein a rotation of the planet wheel carrier (10) brings about a phase adjustment between the camshaft (1) and the drive.Type: GrantFiled: April 9, 2008Date of Patent: December 11, 2012Assignee: Mahle International GmbHInventors: Thomas Hale, Jonathan Hall, Hermann Hoffmann, Gordon Taylor

Patent number: 7845075Abstract: A camshaft has at least two completely machined individual cams fixedly mounted on a shaft in predetermined angular positions. The shaft includes an outside shaft and an inside shaft arranged concentrically in the former, and is to be manufactured in such a way that remachining of the joined camshaft is not necessary. This is by combining the individual cams even before they are mounted on a shaft and joining them to this shaft to form a machining module, such that the individual cams are combined in their mutual arrangement in relation to one another in which the cams are to be mounted on the finished camshaft. The final machining of the cams is performed within this machining nodule. When the cams are completely machined in this way, the cams are joined to the shaft of the camshaft within the machining module. This ensures that the desired mutual arrangement is maintained, i.e., that remachining is not necessary.Type: GrantFiled: July 15, 2005Date of Patent: December 7, 2010Assignee: Mahle Ventiltrieb GmbHInventors: Oliver Fritz, Tilo Hentschel, Hermann Hoffmann, Martin Lechner
