1. A linkage for clutch control forks, in particular for self-propelled vehicules, the fork (15) being situated in a housing (1) and being capable of acting on a cluth thrust bearing (13) cooperating with a resilient element (11) for the purpose of separating plates (5, 10) from a disc on either side of which the plates are disposed, and comprising a first lever (19) connected at one of its ends by a force transmitter to a pedal or lever operated by the driver, and at its other end to a spindle (16) which is pivotally mounted in the housing (1) and carries at least one other lever (17, 18) cooperating with the said clutch thrust bearing (13), characterized in that the said spindle (16) is pivotally mounted in the casing (1) by means of two knife-edge bearings (21, 22), the knife edges (24, 29) being aligned along the direction of the forces exerted at the level of each said bearing and resulting on the one hand from the force exercized by the force transmitter on the first lever (9) and on the other hand from the force exercized by the clutch thrust bearing (13) on the said other lever (17, 18). |
