A tractor (10), which comprises a boom (21) and a bucket (26) being coupled with each other in series and having the same rotating direction, and a control level (19) for operating both the boom (21) and the bucket (26), wherein: a control button (19d) is equipped in the control lever (19), and the control lever (19) can operate either a boom (21) or a bucket (26) after either the boom (21) or the bucket (26) is selected by pressing the control button (19d).

Es wird eine Ausrückeinrichtung für eine Kraftfahrzeugkupplung beschrieben, welche einen axial, entlang einer Ausrückachse verschiebbaren Ausrücker umfasst, der zur Übertragung einer Kupplungsbetätigungskraft mit einem Ausrückorgan der Kupplung in Wirkverbindung steht. Die Ausrückeinrichtung weist weiter einen um eine Lagerstelle schwenkbar gelagerten Kupplungshebel auf, der einen Kraftaufnahmebereich zur Aufnahme der Kupplungsbetätigungskraft von einem Stellglied und einen Kraft-übertragungsbereich aufweist, welcher sich zur Übertragung der Kupplungsbetätigungskraft mit dem Ausrücker an einer Anlageposition in Wirkverbindung befindet und wobei die Lagerstelle ein erstes Lagerelement an einer zu der Ausrückeinrichtung ortsfesten Baugruppe und ein zweites Lagerelement am Kupplungshebel umfasst.

Zur Reduzierung von unerwünschten Reibkräften, die bei einem Betätigungshub infolge einer radialen Verlagerung der Anlageposition des Kupplungsghebels am Ausrücker verursacht werden, wird vorgeschlagen, dem Ausrückhebel Ausgleichsmittel zuzuordnen, welche eine Ausgleichsbewegung mit mindestens einer Radialkomponente bezüglich der Ausrückachse erzeugen.

An electric switch of mechanical structure and functioning, and with electric contacts by means of membranes, suitable for optionally arranging seven different control signals by means of other such contact positions selectively induced by a single button means, four of these positions are differentiated when a slight rolling movement is carried out on said button means in any of four opposite directions and 90º equidistant from each other, a fifth contact position in its clockwise axial rotation, the sixth position by means of its counter-clockwise rotation, and a last contact position by means of a linear pulsating movement.

An electric quadrant switch (10) is provided with a plastics material housing (11) in which stationary and movable contact elements (46, 47) are received, with an actuating member (18) which, for actuation of the movable contact elements (46, 47), is held in the plastics material housing (11) in such a way that it can be pivoted from a neutral position in preferably four actuation directions, the actuating member (18) having an actuator axis (21) and radially projecting actuating arms (20), and with components (24, 25, 41) causing the readjustment and sustained adoption of the neutral position by the actuating member (18). In order to achieve a good haptic sensation and a detectable switching sensation in a small installation space and with relatively low expenditure and to achieve low transmission resistances, it is provided that a switching transmission mat (51) which overlaps the movable contact element (47) at least between the contact elements (46, 47) and the actuating arm (20) of the actuating member (18) for switching movement transmission and in that the actuating arm (20) is provided at its free end with an axially projecting spring-loaded latching element (25) which, during actuation, is guided along a connecting link (41) which, in the neutral position of the actuating member (18), has a latching face (44),

Eine bekannte Hebel-Drahtzugverbindung läßt sich nur sehr schwer montieren.

Hiergegen weist die neue Hebel-Drahtzugverbindung daher die Merkmale auf, daß der Drahtzug (3) eine aufgepreßte oder angespritzte Kugel (6) aufweist, die mit dem Drahtzug (3) in eine zylindrische Hebelausnehmung (7) eingesetzt ist und innerhalb dieser Hebelausnehmung (7) in Axialrichtung der Hebelausnehmung (7) durch beiderseits des Hebels (2) an den Rändern (8, 9) der Hebelausnehmung (7) anliegende Drahtzugabschnitte (10, 11) gehalten ist.

Hierdurch ist der Einsatz bei Kraftfahrzeugen möglich geworden.

A switch (10) for use on the steering column of a vehicle includes lever operated switch members controlling vehicle operating circuits. A switch lever (16) is mounted in a housing (12) attachable to the steering column of a vehicle for movement in one of two mutually separate planes and/or rotation about a longitudinal axis extending through the switch lever. Actuators (26,28,30) are mounted in the housing (12) and are independently responsive to one of the modes of movement of the switch lever (16) for controlling a separate switch member (34,36,38) mounted in the housing. Each switch member carries electric contacts which are selectively engaged by contacts carried by a driven member in the switch member as the switch member switches position in response to movement by the associated actuator to effect switching of the connections for a particular vehicle operating circuit.

An operating device for a motor-vehicle gearbox in which a gear lever (1) operates an actuator (A₁) for selecting and an actuator (A₂) for engaging the gear ratios of the gearbox by means of a shaft transmission (2) and a flexible-cable transmission (3), respectively.

A control device attachable to the handlebar (4) of a bicycle for controlling a brake mechanism and change speed mechanism. The control device comprises a bracket (1) fixed to the handlebar and a brake lever (2) pivotable crosswise relative to the bracket. The brake mechanism is controlled by fore and aft pivotal movement of the brake lever, while the change speed mechanism is controlled by sideways pivotal movement of the brake lever (2).

In order to render an actuator which is capable of selectively operating two remotely arranged latches or the like devices (102,104) highly compact, the device is provided with a reversible motor, a reduction gear and an clutch arrangement which includes a solenoid coil. In some embodiments the clutch includes a two stage arrangement which perits a small power economical solenoid arrangement to be used. The invention further features the use of a compact reduction gear which includes two ring gears (126, 128) and stepped pinion gears (124).
