A potentiometer includes a rotatably mounted lever which acts as a follower member adapted to lie in contact with a moveable finger, the movement of which the lever is to follow, the lever being biassed at all times towards the finger by resilient return means.The lever is in the form of a fork having two arms whereby it is adapted to embrace the finger. Whichever one of these arms is in the trailing position with respect to the direction of rotation in which the lever is biassed by the return means is longer than the other arm. In the embodiment described, the longer arm is an active arm, the shorter arm being a security arm.
摘要:
A friction clutch device for coupling a first rear motor shaft to a second front forced shaft by allowing free relative axial displacement between the two shafts. The clutch device includes a double shock-absorbing steering wheel having a primary couple input assembly which is fixedly mounted axially to the motor shaft, a secondary couple output assembly which is rotatably connected to a reactive plate of the clutch device which is supported by the forced shaft. An elastic circumferential action member is arranged in a cavity that is peripheral to the primary assembly to rotatably connect the secondary assembly, with circumferential shock absorption, to the primary assembly. The secondary assembly is fixedly mounted axially relative to the reactive plate.

An actuator, especially for a motor vehicle clutch, is of the kind that has a casing carrying a reversible electric motor which has a drive spindle, a driving element for coupling the actuator to an actuating member of the clutch, a coupling mechanism which couples the motor drive spindle to the driving element and which includes a toothed sector plate coupled in rotation to the driving element. The coupling mechanism also includes an actuating force reducing mechanism having a compensating spring. The actuating force reducing mechansim includes a compensating lever which is articulated on the toothed sector plate and on an intermediate pivoting lever, which is itself articulated to the casing, the intermediate pivoting lever being coupled to the compensating spring.

A servo control device comprises a motor and continuously acting friction device, which is coupled to the output shaft of the motor and arranged in a housing having an aperture through which the motor output shaft extends. The housing is mounted so as to float radially in a mounting which is provided for it in a casing. Resilient tongues are provided so as to act between the housing and the mounting. The invention is particularly applicable to the motorized servo control of a clutch.

A device for maintaining a clutch release bearing in contact with a clutch cover assembly at all times comprises a clutch release bearing operating shaft, a motorized actuator and coupling devices coupling the actuator to the shaft. These coupling devices incorporate a gear unit driven by the actuator and a toothed sector meshing with the gear unit and rotating freely on the shaft. The toothed sector cooperates with a lever fastened to the operating shaft through the intermediary of a thrust device which is implemented with play. An elastic device for presetting the force with which the clutch release bearing bears on the clutch cover assembly when the clutch is engaged, is disposed between the toothed sector and the lever and operates to increase the play of the thrust device.

Power-assisted steering device for motor vehicles.The steering column is in two parts 13A and 13B which have between each other a limited degree of relative angular play and which receive rotor discs 23A and 23B of a hydraulic distributor 21. The rotor discs 23A and 23B are housed in a cavity 25 of a casing 26, with a small degree of axial play between a base 27 of the cavity 25 and a closure member 28 fixed to the casing 26. The closure member 28 is positioned with respect to the casing 26 by lugs 51 which are applied so as to abut against the base 27. The closure member 28 is fixed to the casing 26 by a weld 50.
摘要:
A hydraulic distributor device comprises two members movable relative to one another, either in rotary or translational movement, along a planar sliding interface, at least one narrow groove being provided superficially in one of the members along the interface, so as to minimize or eliminate the axial thrust generated by the fluid pressure. The distributor device may be used in power-assisted steering apparatus for a vehicle.
摘要:
A power-assisted steering device for a vehicle. The two parts (13A and 13B) of the steering column have the limited relative angular play permitting an angular offset of the rotor discs (23A, 23B) of the distributor (21). The parts (13A and 13B) are coupled by a torsion bar (52). An annular sealing gasket (70) is engaged in the perforation (50) of at least one of the parts (13A and 13B) round the main portion (53) of the torsion bar (52) and is applied against a widened head (56) of this torsion bar (52). The torsion bar (52) has, between the main portion (53) and the widened head (56), a fillet (57) against which the annular sealing gasket (70, 70') wedges itself. In this way, perfect leak-tightness is provided between the distributor (21) and the outside environment.
