ABSTRACT:
A wide-angle joint for use in torque transmission couplings between a driving vehicle, such as a tractor, and a driven implement, such as an agricultural machine, includes a pair of universal joints, one connected to the driving vehicle and the other to the driven implement, interconnected by a double inner yoke. The yoke has outer limbs associated with each of the universal joints. Two gear segment pairs, disposed in meshed engagement are supported on the outer limbs of the yoke, each associated with a different universal joint. The gear segment pairs execute a joint rolling movement in a tilting plane disposed at an angle of more than 0.degree. and less than 90.degree. relative to surface over which the driving vehicle travels. An elongated spring is connected at one of its ends to the wide-angle joint and at its other end to an attachment between the vehicle and the implements. The spring maintains the tilting plane of the gear segment pairs at the desired angle.
