Abstract: Device for coupling two shafts end-to-end, comprising a pair of dog clutch members (16, 28). Each dog clutch member is configured so as to be able to be secured to an end of a shaft to be coupled, and the two dog clutch members (16, 28) have complementary shapes. A first dog clutch member (16) is pivotably mounted in a first casing (6). A second dog clutch member (28) is pivotably mounted in an intermediate bearing (8). The intermediate bearing (8) is slidably mounted in a second casing (10) assumed to be fixed, the intermediate bearing (8) being able to slide relative to the second casing (10) in a direction parallel to the two shafts to be coupled, termed the longitudinal direction. The intermediate bearing (8) is elastically prestressed in the direction of the first casing (6).

Abstract: The invention relates to a hitching device including: a hitched frame mounted onto a tool, such as an agricultural tool; a hitching frame mounted onto a hauling system of a vehicle, such as an agricultural tractor, provided with a power take-off; and transmission means comprising coupling members that are suitable for being moved between a released position and an engaged position and are mounted onto the frames such as to be translatable along a vertical axis (z) and freely rotatable about a so-called “transverse” axis (y). Moreover, a prepositioning means is suitable for keeping, in the released position thereof, both coupling members in a predetermined position along the vertical axis (z) and for enabling, in the engaged position, the displacement of said coupling members, coupled along the vertical axis (z), and tilting of the latter about the transverse axis (y).

Abstract: The invention relates to a device for coupling an agricultural implement to an agricultural tractor (1), comprising two frames (10) each provided with two base plates (11a) arranged such that each base plate (11a) of the frame (10) carried by the agricultural tractor (1) is brought into position under the base plate of the frame carried by the agricultural implement, in such a way as to form, with the latter, a pair of base plates consisting of a base plate pierced by a hole of predefined cross-section and dimensions and a base plate (11) comprising a centering member (18, 19) of decreasing cross-section starting from a base section of dimensions and cross-section matching those of the hole of the other base plate. In addition, tilting means are designed to cause, in a position where the centering members (18, 19) are partially engaged with the facing holes, a relative tilting of the two frames during which said centering members serve as the pivot for said tilting.
