ABSTRACT:
A telescopic power transmitting unit. The power transmitting unit includes a tubular inner member having an outer longitudinal cylindrical section connected to a universal coupling and an inner splined section which is mounted for axial sliding movement within a central member having inner and outer splines extending the full length of the central member. An outer tubular member has an outer longitudinal cylindrical section connected to a universal coupling and an inner splined section which is mounted for sliding movement with respect to the outer spline of the central member. Circumferential guide rings are mounted on the inner and outer surfaces of the central member and aid in guiding the cylindrical sections of the inner and outer members relative to the central member and serve as stops to limit extension of the inner and outer members. A floating cylindrical shield is spaced radially outward of the outer member to prevent foreign material from contacting the splined sections.
