STABILISING COUPLING DEVICE OF TRAILED ASYMMETRICAL MACHINE ON MACHINE-TRACTOR UNIT Russian patent published in 2023 - IPC A01D75/28 A01B59/41 B60D1/00 

FIELD: agriculture.

SUBSTANCE: stabilizing coupling device of a trailed asymmetrical machine on a machine-tractor unit contains a traction lever (1), connected with the front part to the tractor through a hinged mount, and with the rear part fixedly connected to the frame of the trailed asymmetrical machine, resting through the running wheels on the supporting surface of movement. The traction lever (1) is made in the form of a square pipe, in the internal cavity of which installed with the possibility of longitudinal movement relative to this lever (1) fork, consisting of upper and lower horizontally located eyes (5 and 6), fixed on a support platform (7), located in a vertical transverse plane, preloaded by a compression spring (8), abutting the front part into the support platform (7) of this fork, and the back part resting against the collar (9) made on the inner surface of the traction lever (1). In the horizontally located eyes (5 and 6) of the fork, a cylindrical roller (11) is installed with the possibility of rotation on a vertical axis (10). On the front part of the traction lever (1) there is a rotating platform (12) made in the shape of a cylinder sector, mounted on the traction lever (1) with the possibility of angular rotations relative to the vertical kingpin (13) connected to the traction lever (1) by means of (1) brackets (14). The axis of the king pin (13) coincides with the geometric axis of the cylindrical surface of the turntable (12). One flat side surface of the turntable (12) faces the tractor and is connected by means of brackets (15) mounted on the turntable (12) and a horizontal transverse axis with a fork-flange (17) mounted on the tractor with the possibility of rotation relative to the tractor in the transverse vertical plane, and the other with a flat side surface in contact with the roller (11). The rotating platform (12) faces the asymmetrical part of the trailed asymmetrical machine.

EFFECT: reduction in the lateral deviation of the trailed machine from the straight path of the tractor.
