Patent number: 10589776Abstract: An assembly method in which an assembly ring is force-fitted between a first part and a second part such as to create: a tightening contact between the first part and the inner face of the ring, by means of plastic deformation of the ring, said tightening contact occupying a first interference zone; and a tightening contact between the second part and the outer face of the ring, said tightening contact occupying a second interference zone. The assembly ring comprises a first ring segment (T1) and a second ring segment (T2) which are stepped axially in relation to one another and which have different radial dimensions from one another, such as to confine the first interference zone to the first ring segment (T1) and the second interference zone to the second ring segment (T2), in order to prevent the first interference zone and the second interference zone from overlapping axially.Type: GrantFiled: April 6, 2016Date of Patent: March 17, 2020Assignee: JTEKT EUROPEInventors: Patrice Brochot, Julien Stephanus

Patent number: 8826763Abstract: The invention relates to a pusher device (8) that includes a rotary bearing (10) having an inner periphery (11) that is off-center relative to the outer periphery (12). In order to compensate for wear, the bearing (10) is rotationally urged in one direction (F) by a spring (10) and is thus pressed against the back (9) of a rack (3) that is then pushed back against the teeth of the steering sprocket (5). The rotary bearing (10) is rotatingly mounted in a housing (13) that is in turn mounted on a steering casing (2) so as to be capable of sliding in a direction (B) parallel to a plane (P) of the teeth (6) of the rack (3) and orthogonal to the axis (A) of said rack. Shock-absorbing spring means (20, 21) are arranged between the sliding housing (13) and the steering casing (2) for absorbing the straightness defects of the rack (3).Type: GrantFiled: October 29, 2009Date of Patent: September 9, 2014Assignee: JTEKT EuropeInventors: Nicolas Plataret, Patrice Brochot
