Structure design and working principle of rolling & propulsive hydraulic cylinder

Aimed at the linear reciprocating motion or rotary movement of the existing hydraulic actuators,a new hydraulic actuator of rotary propulsion hydraulic cylinder was proposed.Coupled with the traditional vane hydraulic motor and hydraulic cylinder,hydraulic motor turning movement parts we used to replace hydraulic piston in the cylinder part.In the same action of hydraulic source,the reciprocating propulsion and rotating combined motion with load capacity was realized in a single cylinder with two oil circuit.Because of the combined motion based on the same hydraulic source,the hydraulic oil in the cylinder can automatically realize soft flow distribution.The result show that the rotation reciprocating motion of hydraulic cylinder has the features of good adaptive characteristics in elastic feed and energy complementary.
