Abstract: A ground shaping machine, particularly an agricultural machine, including a frame, at least one roller fitted with a flexible tire, a first bearing and a second bearing whereby the roller can rotate about a substantially horizontal axis in the working position, the first bearing and the second bearing being positioned one at each end of the roller. The frame has a first support and a second support, the first support at least being connected to the first bearing through a suspension device including a mechanism with an upper arm and a lower arm, both substantially horizontal and perpendicular to the axis of rotation of the roller, each of the upper and lower arms being connected by a joint to the first support, and to the first bearing, the mechanism forming a deformable quadrilateral, while the suspension device also have a substantially vertical resilient return member connected by a joint to the first support and to the first bearing.

Abstract: The invention relates to a ground shaping machine, particularly an agricultural machine, comprising a frame (3), at least one roller (11) fitted with a flexible tire (13), a first bearing (37) and a second bearing (37) whereby the roller (11) can rotate about a substantially horizontal axis (XX) in the working position, the first bearing (37) and the second bearing (37) being positioned one at each end of the roller (11).

Abstract: A control assembly for operating an agricultural tractor has control members (21, 22, 23, 25, 26) grouped onto a control unit (20) carried by an arm rest (1) intended to be associated to the driver's seat of the tractor. The arm rest (1) comprises a body (2) connected to a support (3) in a swingable way with adjustable inclination, as well as in a longitudinally slidable and adjustable way, and also in a rotatable way with adjustable angular position.

Abstract: A clutch cover is made in one piece for use in an automobile clutch cover assembly comprising, in addition to the cover, at least a pressure plate and adapted for fastening to a reaction plate. The cover comprises, on its periphery, an alternating sequence of radial zones for coupling to the pressure plate and areas for fastening to the reaction plate. These fastening areas each comprise an axial spacer zone aligned with a radial bearing zone, a plurality of holes for fastening members to be passed through and, in the area of the junction between the spacer zone and the bearing zone, a respective bending aperture aligned with each of the holes.

Abstract: A multidisk clutch comprises an external bell member adapted to be coupled to a driving shaft and an internal ring member concentric with the bell member adapted to be coupled to a driven shaft. A plurality of disk members are disposed between the bell member and the ring member. Certain of these disk members are constrained to rotate with the bell member and the remainder with the ring member. A lubricating and cooling liquid is fed into the interior of the ring member, and can reach the disk members through a plurality of holes in the ring member. A generally annular scoop member is rotatably disposed within the ring member. It is constrained to rotate with the driving shaft and has a cylindrical peripheral wall disposed between the liquid feed means and the ring member. Its dimension in the axial direction is substantially the same as that of the ring member.

Abstract: A motor vehicle clutch is provided with a cover which has, on its periphery, zones for fastening the cover to the reaction plate alternating with zones for coupling the cover to the pressure plate. The fastening zones are axially offset from the coupling zones and are provided with radial bearing lugs alternating with axially extending skirt portions which form spacers between the lugs and the reaction plate. The cover is fastened to the reaction plate by screws which pass through apertures in the lugs and into corresponding tapped bores in the reaction plate.

Abstract: A clutch friction disk comprises two friction facings attached by fixing members in the form of rivets to respective sides of a support. Balancing means are associated with the rivets, which to this end comprise an axial bore adapted to accommodate a balancing weight.
