Abstract
A swash-plate transmission drive system including a rotary driven shaft, reciprocally movable drive shafts, a swash plate secured on said driven shaft, and sliding members, each having a flat surface engaging said plate and a spherical surface engaging one of said drive shafts.
Claims14
A drive system comprising a shaft which is journalled to be rotatable in a frame and on which a plate is provided which cooperates with at least one sliding body, one flat side of which cooperates with a running surface on the side of the plate which faces said body, the said running surface being formed by a face which encloses an angle with the center line of the rotatable shaft, the sliding body being provided with a spherical face which cooperates with a corresponding face in a head of a drive rod, the arrangement being such that when the shaft rotates, the sliding body and the drive rod cooperating therewith perform a reciprocating movement, characterized in that the running surface is formed by a face which is constructed to be convex at least in the relative movement direction of sliding body and running surface.
In a transmission drive system including a frame, a shaft mounted in said frame for rotation about its axis, at least one drive rod reciprocally movable along an axis generally parallel to said shaft axis and including a drive end with a spherical surface, a swash plate secured to and rotatable with said shaft and having a running surface which extends transversely of the shaft axis and defines therewith an angle, a sliding body operable with each of said drive rods, said body having opposite first and second sides, said first side defining a flat surface in sliding engagement with said running surface of the plate, and said second side defining a spherical surface in sliding engagement with the spherical surface of said drive end of the drive rod, the improvement in combination therewith wherein said running surface of the plate is convex at least in the direction of movement of said sliding body relative to said running surface.
