Abstract: A device for adjusting the level of a motor vehicle comprises an electric motor (4) and an actuating gear (3) which is connected upstream of a screw drive (2). The actuating gear (3) is formed by three series-connected gears (14, 15, 16) with parallel rotation axes (D14, D15, D16). An input gear (14), the number of teeth of which is at least one and at most five, is coupled to the motor shaft (17) of the electric motor (4) for conjoint rotation. The input gear engages with an intermediate gear (15) which engages with an output gear (16) which is connected to a nut (9) of the screw drive (2) for conjoint rotation.

Abstract: An actuator for level adjustment of a motor vehicle utilizes a ball screw and a locking unit provided for blocking the ball screw. The actuator has a spindle drive which can be actuated by an electric motor via a gear. The spindle may be fastened to a damper of the chassis of a motor vehicle, to a wheel carrier or to the body or a subframe of a motor vehicle. With the aid of a locking unit of the spindle drive, the rotation of the spindle nut can be optionally blocked or enabled. The locking unit includes a locking element which engages a locking contour attached to the end face of a rotatable element of the gear.

Abstract: The invention provides a double clutch transmission (100B), wherein for each of the countershafts (6; 7), between the corresponding driving gear (23; 24) of the corresponding countershaft (6; 7) and at least one of idler gears (8, 9, 10; 11, 12, 13, 14) of the corresponding countershaft (6; 7), there is disposed a bearing (33A; 35A) of the corresponding countershaft (6; 7). The construction of the transmission can be allowed to be more compact according to the invention.

Abstract: The aim of the invention is to be able to make transmissions, in particular dual-clutch transmissions, more stable and compact, especially in respect of a variable moment load. The aim is achieved by a transmission comprising two coaxial transmission input shafts, two countershafts on which gear wheels designed as idlers are rotatably mounted, gear wheels that are arranged in a rotationally fixed and axially successive manner on the two transmission input shafts, are designed as fixed gears, and indirectly or directly mesh with the idlers and thus define different gears, coupling devices which are mounted in a rotationally fixed and axially movable manner on the two countershafts and are to be axially moved by means of adjusting mechanisms in order to connect one respective idler in a rotationally fixed manner to the respective countershaft, and one respective output gear which is mounted on the two countershafts and meshes with teeth of an output member.

Abstract: In order to be able to design a connection between a drive side and a transmission side, in particular a damper side, in a drivetrain between a main driveshaft and a torsional vibration damper to be structurally stronger while at the same time having a small installation volume, the invention proposes a drivetrain with a main driveshaft and a torsional vibration damper, wherein the main driveshaft and the torsional vibration damper rotate substantially about a common rotational axis and are connected by means of a connection, wherein the connection can be released in a non-destructible fashion and/or is self-connecting, and wherein a wall is arranged axially between the driveshaft and the torsional vibration damper, which wall is sealed off against the drivetrain by means of a seal, and the drivetrain is characterized in that the connection is arranged radially further remote from the common rotational axis than the seal and than the main driveshaft.

Abstract: In a control mechanism with a switchable transmission path comprised of mechanism links mounted on a frame, and with a switching pinion gear, through which at least two mechanism links can be optionally incorporated in the transmission path for switching purposes, wherein the two mechanism links are moveably held on a mount of the frame via switching elements, and wherein the switching pinion gear acts through a switching path to select and/or engage or disengage one of the two mechanism links on the switching elements, the mount can encompass a bearing element that is arranged so that it can move relative to the frame, and comprises part of the switching path, and an insertion lockout can be securely fastened to the frame, and the switching elements can be secured to the mount by means of an axially divided bearing block.
