SLEWING RING OF A TWO-AXLE TRAILER Russian patent published in 2023 - IPC B62D63/08 B62D53/00 

FIELD: slewing devices.

SUBSTANCE: invention relates to slewing devices for a two-axle trailer. Slewing device comprises a traction lever pivotally connected to the tractor, a turntable fixed on the frame of the front wheeled bogie and connected to the frame of the trailer body by means of a pivot. The turntable consists of two cylindrical plates - upper and lower, connected by means of a pivot. The top plate is connected to the trailer body frame by means of brackets fixed to the body frame and the horizontal transverse axis. The bottom plate is connected to the front swivel bogie through brackets attached to its frame and a horizontal transverse axle. The bottom plate of the platform is kinematically connected to the tractor through a connecting rod, the front end of which is fixed to the tractor by means of a ball joint, and the rear end is connected by means of a ball joint to the free end of the pendulum lever fixedly fixed on the lower plane of the lower plate.

EFFECT: reduction of lateral horizontal deviations (wobbles) of a two-axle trailer during rectilinear movement and absence of obstacles when making turns of an autotractor train during maneuvering, due to the possibility of damping transverse vibrations of a two-axle trailer.
