steering control for a troghetsbroms approaches for the shoulder of a vexellada

摘要

The invention relates to an operating control device for an automobile engine assembly unit comprising successively a clutch and a gear-box equipped with an inertia brake, the control comprising a pressure plate carried on a declutching stop and adapted, by an axial displacement of the clutch in the direction of action, to apply a friction disc against a reaction surface on the casing of the gear-box, the disc being keyed for rotation with the input shaft of the gear-box while remaining axially slidable on this shaft; the control device further comprises a unidirectional axial coupling device located between the declutching stop and the pressure plate, this unidirectional coupling permitting an axial sliding movement of the pressure plate only in the direction opposite to the direction of action, and retaining members intended to engage the pressure plate when the declutching stop moves in the direction opposite to its direction of action. The declutching stop acts by traction or by thrust, the pressure plate thus acting conversely by thrust or by traction.
