Definitions
- the present invention relates to a mechanical device for actuating a piston relative to a cylinder, in particular in a disc brake, this device comprising a pusher integral in translation with the piston, a lever mounted to rotate relative to the cylinder in an axial plane of the latter.
- a ball joint connecting one end of the lever to one end of the pusher to allow relative rotation of this lever and of this pusher, a means for guiding in translation the pusher in the cylinder, a rolling surface fixed relative to the cylinder and forming a cam , and at least one rolling member bearing on the surface forming a cam to allow the lever to roll on this surface, this rolling being accompanied by a rotation of this lever around the ball joint and a translation of this ball joint and of the pusher relative to the cylinder.
- the present invention aims to provide a brake motor of the type defined above, of simple structure, but nevertheless allowing to animate the pusher with a pure movement of axial translation.
- the device of the invention is essentially characterized in that the rolling member bears only on the rolling surface at a single point on the axial plane of the cylinder.
- the ball joint is constituted by a ball sandwiched between the end of the pusher and the end of the lever and the rolling member is a roller mounted to rotate on the lever.
- the cam surface can be essentially constituted by an inclined plane and the pusher can be biased towards the lever by at least one Belleville washer.
- the device concerned mainly intended to allow the mechanical actuation of the piston 1 of a disc brake relative to the cylinder 2 of the latter, essentially comprises a pusher 3 integral in translation with the piston, a lever 4 rotatably mounted relative to the cylinder 2 in an axial plane of the latter, namely the plane of the figure, and a ball joint formed by a ball 5 sandwiched between the end 3a of the pusher and the end 4a of the lever and connecting these ends to allow relative rotation of this lever and this pusher.
- the pusher is secured to a means for guiding in translation, for example taking the form of a plate 6 capable of sliding in a bore 2a of the cylinder, and the pusher 3 is biased towards the lever 4 by a stack of Belleville washers, such as 7, tending to push back the guide plate 6 from a fixed part 2b of the cylinder.
- the rolling member that constitutes the roller 9 is only supported on the rolling surface 8 at a single point 8b of the axial plane of the cylinder, which results in that the pusher is driven by a pure axial translation movement.
- point 8b in question is that which corresponds to the trace, in the axial plane of the device which contains the rotational movement of the lever, of the zone in which the rolling surface 8 and the roller 9 are tangent l to each other.
- point 8b actually has only a virtual existence in the illustrated embodiment, since the axial plane, constituted by the plane of the figure, in this case passes through the opening 8a, at the level from which the roller 9 and the rolling surface 8 cannot be in contact with one another.
- the lever 4 can be provided with a roller such as 9 on either side of the elongated opening 8a, so as to avoid the appearance of any force perpendicular to the axial plane, that is to say in the plane of the figure.
