Abstract:
An externally splined clutch hub and method for making the same is disclosed wherein a flat circular metal perform (10) is contacted with a single forging die to simultaneously cold forge a centrally disposed tubular neck (14) extending outwardly from one side of the perform and simultaneously a splined annular ring (16) at the periphery of the perform and extending outwardly from the other side of the perform wherein the tubular neck and the annular ring are coaxial.
Abstract:
A clutch-driven limited force actuator is disclosed having a motor, a planetary gear mechanism in operative communication with the motor and a clutch plate. The clutch plate includes a contact surface selectively in frictional contact with the planetary gear mechanism to drive an actuator arm. In operation, the frictional force between the planetary gear mechanism and the clutch plate causes the actuator arm to actuate. The actuator arm can be connected to any element that requires actuation. The actuator of the present invention is preferably used in a wheelchair lift to actuate any mechanism that must have a safe limit on the amount of force applied to obstacles and that must have provision for direct manual operation.
Abstract:
The present invention concerns a brake system creating redundancy in electromechanical brakes (1). At least two drive units (2) are provided at each single brake (1) for activation of the brake. The at least two units (2) may be controlled and/or energized separately. To safeguard the function the control and/or energy source systems are formed in two nets (5, 6). The at least two units (2) of each brake (1) are connected to separate nets (5, 6). The at least two units (2) may be separate electrical motors.
Abstract:
The invention relates to a plug-in coupling (1) having a positive coupling partner (2) that is inserted in a receiving opening (10) of a negative coupling partner (5) with its insertion end (3) first. The coupling partners have corresponding wall elements that engage with each other in a turn-lock manner, thereby ensuring a turn-lock relative engagement position of rotation (7) of the turn-lock wall elements (6) of the coupling partners in the inserted position. The aim of the invention is to allow to insert the coupling partner without visual contact. For this purpose, the insertion end (3), along practically the entire covering ends (8) of the outer periphery (13) thereof, is provided with substantially concave insertion recesses (12) which correspond to the turn-lock wall elements (6) of both coupling partners and/or to the insertion recesses (12) of the respective other coupling partner in terms of number, arrangement and geometry in such a manner that they allow a restricted guidance that aligns at least one coupling partner, when the latter is inserted, in the sense of a turn-lock engagement position of rotation of the coupling partners relative to one another.
Abstract:
The invention relates to a method for operating a motor vehicle. According to said method, at least one control parameter is stored in a memory in addition to a first storage of the adaptive parameters. The invention also relates to a motor vehicle with a device for carrying out the inventive method.
Abstract:
An electro-mechanical actuator is provided resisting back driving of a gear train in at least one direction. The actuator includes an internal gear train (101). A clutch (111) is coupled to an output of the gear train and transmits a driving force from the gear train to a clutch output. When a back driving force is applied to the clutch output in at least one direction, the clutch assumes a locked configuration. When the clutch is in a locked configuration the clutch resists rotational movement of the output and back driving of the gear train.
Abstract:
A powertrain clutch for transferring power from an output shaft of an engine to an input shaft of a manual transmission includes a housing and an electrically controlled clutch between the input shaft and the output shaft for selectively coupling and uncoupling the output shaft and the input shaft. The clutching arrangement further includes a clutch disposed between the input shaft and the output shaft for synchronizing a speed of the input shaft with a speed of the output shaft.
Abstract:
A clutch mechanism body has a rotational drive force output portion installed in a rotational drive force input system, a rotational drive force input portion installed in a rotational drive force output system, and a pressing mechanism portion for bringing the rotational drive force output portion and the rotational drive force input portion into contact with each other by pressing them. The pressing mechanism portion has constant load means and variable load means that produce pressing forces that bring the rotational drive force output portion and the rotational drive force input portion into contact with each other. A load value produced by the constant load means is set to a value less than a maximum slip limit value that is required to transmit a rotational drive force with the rotational drive force output portion and the rotational drive force input portion held in contact with each other.
Abstract:
A pad clip (12) for a disc brake includes a first part configured to engage a brake pad support bracket (2). The clip further includes a spring leg that is positioned to engage the brake pad (4) and apply a force to the brake pad that generates an axial friction force on the brake pad. The clip has a support for receiving a pad return spring (18) and the support for the pad return spring is positioned so that it holds the pad return spring such that the pad return spring applies a return force that is in substantial alignment with the axial friction force. The disc brake is further arranged so that the center of gravity of the brake pads lies between the pad abutment force and the axial friction force.
Abstract:
The inventive actuating unit for an electromechanical disc brake for a motor vehicle comprises a lever arrangement (3) placed between an actuating electric motor and a friction lining (4) of said disc brake. Said lever arrangement consists of a first lever (10) mounted at a level of a hinge point (A or 40) in a stationary manner with respect to a brake calliper (1), and a second lever (20) connected to an actuating element (7) by a driving force. Said actuating element is connected to the friction lining with the aid of an adjusting device (30) which is used for compensating the wear-out of the friction linings (4, 5). In order to reduce to a minimum the power demand of the electrical power drive system and the energy demand of the brake along the life service thereof, the adjusting device (30) is constructed in such a way that the efficient transmission range of the lever arrangement (10, 20) is carried into effect by modifying a deviation (A-C) between the hinge point (A or 40) and a force application point (C or 60) of the adjustment unit (30) to the actuating unit (7), the operating air gap between the friction lining (4, 5) and the brake pad (6) being maintained permanent.
