ABSTRACT:
Hydraulic assisted steering for a motor vehicle comprising a control shaft (1) mounted for rotation in a casing (2) and connected to the steering wheel, a follower shaft (3) also mounted for pivoting in this casing and connected mechanically to a pinion (4) engaged with the steering rack (5) resilient means connecting the control shaft (1) and the follower shaft (3) together so that there is produced a relative angular movement of the two shafts when a torque is exerted on the control shaft (1) a hydraulic valve (13 or 13a-13b) responsive to this relative movement, and an assisting cylinder (10) in the supply line of which the valve is inserted and whose mobile element is connected to the rack (5).
The resilient means connecting the control shaft (1) and the follower (3) together and detecting the torque exerted on the control shaft comprise a first endmost transmission element (17 or 17a) interlocked in rotation with the control shaft (1), a second endmost transmission element (18 or 18a) interlocked in rotation with the follower shaft (3) and coaxial with the first one, and a third intermediate transmission element (22) which is coaxial with the first two and connected peripherally thereto by flexible blades (23 and 26) directed obliquely, in one direction for the first endmost element and in the opposite direction for the second one; the intermediate element (22) is connected to the slide (31) of the valve. FIG. 2.
