Abstract
A steer by wire steering column assembly for a vehicle comprises a shroud having a first shroud portion and a second shroud portion, the two shroud portions being constrained to move telescopically relative to one another for adjustment of a reach position of the steering column assembly; a shaft supported by one or more bearing assemblies housed within the shroud and adapted for supporting a handwheel or another user operable device at a free end; and a linear actuator that includes an elongate threaded rod that is connected at a first location to one of the shroud portions by a first bracket assembly and at a second location to the other shroud portion by a second bracket assembly, the linear actuator controlling the telescopic position of the shroud by causing the threaded rod to rotate around its axis. At least one of the bracket assemblies is adapted to provide a degree of lost motion between the linear actuator and the associated shroud portion that accommodates misalignment of the two shroud portions during use of the steering column assembly that would otherwise apply a bending moment to the linear actuator.
