摘要:
An adjustment device for automatically operating a vehicle transmission, includes an actuator to operate a gear input part that, depending upon a desired gear, assumes a position corresponding to that gear. An emergency operating device is connected to the actuator for activating a tension element to establish an active connection to the gear input part for the purpose of setting a position of the gear input part corresponding to a selected gear during a failure of the actuator.

An adjusting device for operating a friction clutch is brought into active connection with the friction clutch via an output device driven by a drive. The output device includes a compensation device that compensates for a wear-induced position change of the pressure spring of the friction clutch by permitting a length change of the output device. For this purpose, the compensation device includes a fixing device that secures the relative positions of the components of the output device to each other. The fixing device is releasable in a predetermined operating state of the adjusting device by a control element. When released, the fixing device allows the relative movement between the components of the output device required to implement the length change of the output device.

A positioning device for an output component for automatically shifting gears of a motor vehicle transmission that undergoes two types of movements comprises a plurality of drives. The movement of each drive can be transmitted via a transmission mechanism to the output component. A first drive causes the output component to undergo movement of a first type, and a second drive causes the output component to undergo movement of a second type. The first drive is connected to a sliding element. The sliding element is axially fixed, but movable in the circumferential direction relative to the output component. The second drive is rotatably fixed, but axially movable output component.

An actuating device for the automatic actuation of a transmission includes at least two actuating units whose driven parts can be driven in a translatory movement by which a transmission shaft of the transmission can be driven in rotary and translatory movement for gear selection and accelerator selection. The driven parts which can be driven in translatory movement cooperate with a lever element which is connected with the transmission shaft and which is mounted in an articulated manner by means of at least one joint.

An automatic transmission, especially for a motor vehicle, having a plurality of torque transmission paths which can be selectively activated for torque transmission. The torque transmission paths have different transmission characteristics and, based on their transmission characteristics, can be ordered in a sequence of torque transmission paths has a clutch arrangement by which at least one of the torque transmission paths can be activated. It is provided that the clutch arrangement has a clutch unit which is associated with a group of torque transmission paths and by which a torque transmission path of a group of torque transmission paths can be selectively activated. A plurality of groups of torque transmission paths are provided, each group having only one individual torque transmission path, or a plurality of groups of torque transmission paths are provided, at least one group having a plurality of torque transmission paths, or a plurality of groups of torque transmission paths are provided, at least one group having an individual torque transmission path and at least one additional group having a plurality of torque transmission paths. At least one group of torque transmission paths, insofar as it includes a plurality of torque transmission paths, has only torque transmission paths which do not immediately follow one another in sequence.

A friction clutch with at least one flywheel mass and a clutch housing with which there is associated a pressing arrangement for a pressing plate which is provided for the action of pressure on one side of a clutch disk the opposite side of which is supported on a counter pressure surface. Furthermore, a disengager is provided by which, upon its movement, the pressing arrangement can be functionally connected with or separated from the clutch disk. The disengager is connected by a disengagement mechanism to the pressing plate by which the movement of the disengager can be transformed into an axial movement of the pressing plate.
摘要:
An actuating device for automatic operation of a gear change in a transmission that produces a change in predetermined translation ratios of the gear change transmission in any desired sequence comprises first and second drives that are in active connection with a selector shaft. The first drive is connected to the selector shaft via a guide mechanism which comprises at least one constraint guide that corresponds to a shifting path. The second drive is in active connection with the selector shaft for providing an operating force in the axial direction and an operating force in the circumferential direction of the selector shaft. The resulting movement depends on the operating position of the guide mechanism.
摘要:
An actuating device for automatically actuating a manual transmission, which has an output element that can be driven in a first direction by a first drive and in a second direction by a second drive. Each drive is assigned a sensor which displays an actuating movement and detects a movement if the output element and whose signals are fed to a control device. In the case of a movement of the output element the sensors output to the control device signals assigned to this movement, the signals specifying the respective magnitude of the movement. The control device uses the signals with reference to an arbitrary prescribable reference point to determine the actual position of the output element and relate the actual position to a desired position of the output element which is to be approached, with the perception that the desired position has not been reached after termination of an actuating movement, or the absence of the signals which indicate the actuating movement causing the control device to activate an emergency function.
摘要:
An actuator is provided with a housing to hold a drive system, a transmission which converts its motion into an essentially translational movement of an output element, and an electronic subassembly. The housing has a first housing part which contains the transmission and a second housing part which supports the electronic subassembly, which is detachable from the transmission. The two housing parts, when connected to one another, and without any partitions separating them, form a compartment in which the transmission and the electronic subassembly are contained as enclosed components which are three-dimensionally engaged with one another, but are functionally separate from one another.
