FIELD: machine building.
SUBSTANCE: suspension with towing device comprises pin connected with lifting and lowering hydraulic cylinder, and suspension hydraulic cylinder mounted on self-propelled machine frame and connected via lever with rotary shaft. Lower part of suspension is made in form of a welded structure arranged to swing in vertical plane and secured by one end on swinging axis, while other end is connected by flexible link with rotary shaft. Rotary shaft is connected by lower lever with lug attached to rod of lifting hydraulic cylinder of suspension, with possibility of lifting suspension when pressure is applied in piston cavity of hydraulic cylinder of suspension. On upper part of pin there is a spring to generate force retaining pin in closed state.
EFFECT: higher reliability of engagement, increased efficiency of hydraulic system pump of suspension mechanism when operator performs coupling and uncoupling of trailer directly from cabin.
