Turbocharger for vehicle with improved suspension of the actuating mechanism for variable nozzles

A turbocharger in which gas is directed through a first annular passage (30) to the turbine, including a housing (18, 24, 26), a ring of guide blades (34) in the first annular passage (30), which are mounted pivotably on a nozzle ring (38) defining one boundary of the first annular passage, and an annular actuating ring (48) coupled to pivot the blades by movement of the actuating ring in relation to the nozzle ring, and a suspension mechanism (55, 59) for the actuating ring (48) which brings about a coaxial location of the nozzle ring and the actuating ring relative to each other and about the turbine shaft, wherein pins (55) and rollers (49) with grooves (59) are provided about the inner or outer circumference of the actuation ring, which rollers are provided in a second annular passage formed between a housing part (126) and the nozzle ring (38), thereby characterized, that the pins (55′, 55″) engage with one end in a bore in the nozzle ring (38) or a housing part (24, 26), but not both, and that the length of the pins projecting from the bores corresponds approximately to the axial length of the rollers.
