ABSTRACT:
A gear assembly: a gear assembly which is used in a power assisted steering system of a vehicle.
The gear assembly comprises a piston (1) within a cylinder (2), the piston (1) being axially displaceable in response to an input shaft (4). The piston (1) is axially rotatable by means of a track (18) and track follower (19) in response to axial displacement. Splines (40) on the piston (1) intermesh with teeth (42a) of a take off part (42) which is laterally spaced and in side by side relationship with the piston. By rotation of the piston (1) an output shaft (44) of the take off part (42) is rotated. In a modification of the take off part instead of being in side by side relationship is an extension of the piston and the track is of variable curved portions.
