Device for connecting a motor vehicle steering column to a shaft journal of a steering gear train

A device for connecting a motor vehicle steering column to a shaft journal (12) of a steering gear train, wherein the device comprises a coupling piece (1) having a first direction (A) with the coupling piece being U-shaped transversely of the first direction, said coupling piece (1) arranged to be articulated to the steering column for pivotal movement about an axis (2) extending transversely of the first direction, said U-shaped coupling piece (1) having a pair of laterally spaced sides (3, 4) and a bight section (5) extending between and interconnecting said sides, a bore (7) in at least one of said sides, a lock bolt (16) secured against turning in said bore, said sides (3, 4) each have a first side surface facing one another and a second side surface facing in the opposite direction, a stop formed in said lock bolt and arranged to contact the second side surface of the one of said sides (3), a spring (19) pressing said stop (22) of said lock bolt (16) against said second side surface, said lock bolt has a first end surface facing the other one of said sides and a second end surface facing in the opposite direction, and said first end surface (23, 24) of said lock bolt (16) has an axis extending in a second direction transversely of the first direction with said axis traversing said first end surface (23, 24) from a first point to a diagonally opposite second point on an outer circumferential periphery of said first end surface of said lock bolt with the first point being more remote from said bight section than said second point, said first end surface (23, 24) has a wedge-shaped configuration extending in the second direction and when said stop of said lock bolt is pressed against the one of said sides said wedge-shaped first end surface has a first bevel section inclined from the first point inwardly from the one of said sides in the second direction toward said bight section, wherein the improvement comprising that said wedge-shaped first end surface has a second bevel section inclined from the second point inwardly of the one of said sides in the second direction away from said bight section, and said first and second bevel sections (23, 24) each having an angle of inclination relative to the first side surface of said one of said sides and the angle of inclination of said second bevel section being greater than the angle of inclination of said first bevel section.
