BINARY FORK-JOINT Russian patent published in 2012 - IPC F16C11/06 F16D3/32 

FIELD: mechanics.

SUBSTANCE: device refers to duplex hinged joints of agricultural and other machinery. The duplex universal hinged joint contains first spindle (1), and second spindle (2) which are connected pivotally with the intermediate spindle (11) by means of the centre cross (7,8) with inter-perpendicular axes. The spindles (1,2) are additionally inter-connected through the openings in the centre cross (7 and 8) by the arrester of the redundant axis with the ability to level the displacement angles of the spindles' spinning axis (1,2) from the spinning axis of the spindle (11). The arrester of the redundant axis contains first and second ball headed gearwheels (3,4) which are in the interlocking arrangement and are positively connected to the spindle extension housing (1,2). Each gear tooth (3,4) is located in the spherical surface in a circumferential direction, symmetric to the spindle rotation axis, ball headed gearwheel. On the first gearwheel.(3) in the spindle rotation axis (1) the central tooth is located, the surface of which is symmetric to the spindle rotation axis (1). On the second gearwheel (4), in the spindle rotation axis (2) for the central tooth inlet (3) the central low spot is located the surface of which is symmetric to the spindle rotation axis (2).

EFFECT: creation of the duplex universal hinged joint which transmits the predicted rotating torque at the axis cross of its spindles in the 120 degree angle or greater.
