FIELD: transportation.
SUBSTANCE: invention relates to hitch devices of trackless vehicles. Hitch mechanism consists of ball with traction rod, thrust and ball-type spring-loaded retainers. Ball with traction rod with through slot is made of resilient material. Ball-type spring-loaded retainers interact with semi-spherical head of trailer hitch. Traction rod is tapered and has rectangular cross-section, and its through slot, changing into ball, along their entire length is made of different width. Sleeve is spring-loaded by a helical compression spring on the rod. Sleeve has tapered inner surface interacting with ball rod outer surface.
