摘要:
A device for opening and closing an opening (11), in particular in a motor vehicle, by means of a motor-driven, movable part (10), with a control unit (26) and a pinch prevention sensor (14), which is disposed essentially along an edge (20) of the part (10) and/or of a frame profile (12) bordering the opening (11) and which, during the closing of the part (10), detects an obstacle (24) that is in the movement path of the part (10) and sends a signal to the control unit (26) in order to stop or reverse the movement of the part (10), wherein the pinch prevention sensor (14) has a highly elastic, electroactive polymer (EAP) material (30), in particular polyurethane, fluoroelastomer, polybutadiene, fluorosilicone, or silicone, disposed between electrodes (28, 34, 36), which produces a voltage change in the electrodes (28, 34, 36) in the event of a deformation.
摘要:
A wiper blade for cleaning windows, especially of motor vehicles, is proposed, which has an elongated, rubber-elastic wiper strip (20) that can be pressed against the window (22) and is retained by a multi-member support bracket system (12) that has a main bracket (14), located in the middle portion of the support bracket system, is provided with a bolt (26), oriented transversely to the length of the wiper blade (10), for pivotable connection to a wiper arm (28) that is urged toward the window and is driven to swing, resulting in one wiper blade half near the swing axis and one wiper blade half remote from the swing axis, and the wiper blade is provided with spring means, which under tension, when the wiper blade is pressed against the window, additionally urge the half remote from the swing axis toward the window. A favorable embodiment and disposition of the spring means in terms of the masses to be moved is achieved by providing that the spring means are embodied as a leg spring (60), of which one leg (64) is braced directly or indirectly on the pivot bolt (26) and its other leg (66) is fixed to the half near the swing axis of the main bracket (14).
摘要:
The invention is based on a control drive for operating drive components or adjusting components in motor vehicles. The control drive comprises an electric actuator (12) that acts on force-transmitting elements (19, 13; 40, 41). With these, the adjusting motion is transmitted to the drive or adjusting components to be adjusted. A throwout element (19) is provided that interrupts the transmission of force by the force-transmitting elements (10, 13; 40, 41) in the de-energized state (23, 55) of the electric actuator.
摘要:
An electronic triggering device for a two-motor wiper system with two electric motors is proposed, in which the triggering device includes a parallel circuit of three half bridges; one of the three half bridges intended for triggering both electric motors in common. A method for triggering such a triggering device is also proposed.
摘要:
A drive unit for wiper assemblies includes a housing (2, 3; 91) surrounding a drive motor, which is associated with a gear (13, 30, 50, 60, 80, 90), whose drive shaft (5, 40, 65, 97) drive wiper components. On the housing (2, 3; 91), a connecting point (27) for a control and regulating electronics, as well as for connecting to an on-board system of a motor vehicle and a position detector (12), are provided. The drive shaft (5, 40) lies either coaxial to the drive shaft of a rotationally symmetrical motor and drive unit (1, 30, 50, 80) or the axis of symmetry (93) of the motor and gear unit (60, 90) lies in a mirror plane (78).
摘要:
The invention relates to a valve for controlling volumetric flows in a heating and/or cooling system of a motor vehicle, comprising a valve housing (10), from which at least one inlet channel (18) and at least one outlet channel (20, 22) branch, in addition to at least one disc-type valve body (28) for controlling the flow, said body being located in the valve housing (10) so that it can rotate about the axis (31) of a driven shaft (30). According to the invention, the valve comprises means for compensating an imbalance, said means ensuring a uniform distribution of mass about the rotational axis (31) of the valve body (28). The invention also relates to a heating and/or cooling circuit (110) of motor vehicle, comprising at least one coolant control valve (131) of this type.
摘要:
Gear mechanism (10), in particular for adjusting moveable parts in a motor vehicle, comprising a spur wheel (14) which is provided with external teeth (16) and meshes with an internal gear (18) that is provided with internal teeth (20), wherein the number of internal teeth (20) to generate a certain gear step-up ratio is greater by at least one than the number of external teeth (16) and the spur wheel (14) and the internal gear (18) perform an eccentric movement relative to one another, wherein the eccentric movement is directed exclusively by means of the matching tooth geometry of the internal and external teeth (20, 16).
摘要:
The invention proposes a valve (1) for controlling volume flows, in particular in a heating and/or cooling system of a motor vehicle, having a disk-shaped valve body (2) with at least one control opening (3) which, to control the volume flow, interacts with a disk-shaped sealing body (10) having at least one passage opening (11), wherein the disk-shaped valve body (2) has an external toothing (49) into which a pinion (42) engages in order to rotate the valve body (2). According to the invention, the pinion (42) and the external toothing (49) of the disk-shaped valve body (2) interact with one another by means of an evoloid toothing (43; 44). The valve according to the invention is provided for controlling volume flows, in particular in a heating and/or cooling system of a motor vehicle.
