SLEWING DEVICE OF A TWO-AXLE TRAILER WITH A VARIABLE INCLINATION OF THE PIVOT Russian patent published in 2022 - IPC B62D63/06 B62D53/04 

FIELD: slewing devices.

SUBSTANCE: invention relates to slewing devices for two-axle trailers. The turntable of the two-axle trailer comprises a traction arm, a turntable fixed at an inclination in the longitudinal vertical plane on the frame of the front wheeled bogie and connected to the frame of the trailer body with the possibility of turning this platform relative to the frame around the pivot. The tractor is equipped with a hydraulic system with a source of hydraulic fluid pressure and contains an element of the steering system, kinematically connected to the spool of the three-position distributor. The traction arm is made integral with the frame of the front wheeled bogie, and the turntable is made of two parts - upper and lower, connected to each other by means of a pivot.

EFFECT: reduction of the force moment acting on the traction lever relative to the pivot axis is achieved, which helps to reduce the resistance to turning, facilitate the conditions for making a turn and improve the controllability of a transport train with a two-axle trailer.
