摘要:
The invention concerns an automatic alignment system that provides controls of the angle between the tower (A) / trailer (B) and the rotation way of the wheels, and provides the performance of the automatic alignment process in accordance with these controls in vehicles that are used in heavy load carriage, and have hydro-mechanical steering system. The system includes a mechanical control system assembled on the front and rear steering centers (13, 23), inductive sensors (30, 40) assembled on the front and rear steering centers (13, 23) along with the mechanical control system, generating digital signal regarding the mechanical control system, an electric control circuit (60) providing the automatic performance of alignment by controlling the hydraulic steering system in accordance with the signals received from the mentioned inductive sensors (30, 40), and a wired or wireless remote control with a lighted warning (70) providing commands for left steering, right steering, and automatic alignment functions by working connectedly with the electric control circuit (60), all for providing the control of the alignment situation between the direction of rotation of the wheels and the tower (A) / trailer (B).

The invention relates to a heavy-transport vehicle (10) for transporting an elongated object, having a tractor (14), a multi-axis trailer (16) and a carrier (18), supported on the trailer (16) and on the tractor (14), for the elongated object, the trailer (16) and the carrier (18) being rotatable in relation to each other about a vertical axis (52) of the transport vehicle (10). According to the invention the carrier is supported on the tractor (14) via a goose-neck (22), the trailer (16) has at least one rigid axis (42, 44) and at least one steered axis (40), and, in a steered operating mode during the journey, the steered axis (40) of the trailer (16) is capable of being steered in relation to the trailer (16) as a function of rotational movements of the carrier (18) about the vertical axis (52).

Es wird ein Satteldrehplateau (10) für einen Sattelauflieger beschrieben. Das Satteldrehplateau (10) weist einen Drehteller (12), der einen Königszapfen (14) trägt, einen Drehkranz (16), in dem der Drehteller (12) drehbar angeordnet ist, und eine Aufliegerplatte (20) auf, an der der Drehkranz (16) befestigt ist. Die Aufliegerplatte (20) weist zwei sich in Längsrichtung L des Satteldrehplateaus (10) erstreckende Längsränder (24a,b) und zwei sich in Querrichtung Q des Satteldrehplateaus (10) erstreckende Querränder (26a,b) auf. Die Aufliegerplatte (20) weist am ersten Querrand (24a) einen ersten abgebogenen Schenkel (30) und am zweiten Querrand (24b) einen zweiten abgebogenen Schenkel (32) auf.
摘要:
A steering mechanism for a drawn vehicle to steer one or more turnable steered axles that at least has: • A slewing bearing. • A rocker that is fitted around a vertical shaft and is turnable. • A cable whose ends are connected to the rocker on either side of the vertical shaft and which is fitted around the slewing bearing to transmit a turn of the slewing bearing to the rocker; and, • A tackle at each end of the cable with a fixed pulley that can be coupled to the drawn vehicle, and a movable pulley on the rocker.
