Tripod joints, each of which includes revolvable rollers to be directly fitted to outer circumferential surfaces of spider shafts, are provided respectively at both ends of an input-side shaft to which slave driving force is transmitted. Accordingly, it is possible to prevent a slave driving system from transmission of unnecessary torque, and obtain a slave driving force-transmitting mechanism which is compact and light in weight, having a structure simplified as compared with those of the conventional technique.

Slave driving force-transmitting mechanism for vehicle

In a slide type universal joint, a slider is slidably fitted around a trunnion of an inner member and a roller, which rolls in a transmission groove of an outer member, is carried rotatably on the slider via a needle bearing, the slider and the roller being coupled together against axial relative displacement by an axial coupling means. This makes the joint simple in structure and reduces frictional resistance.

Slide type universal joint

A restriction flange formed integrally on one end of each cylindrical holder in a sliding universal joint abuts the bottom surface of the respective transmitting groove to prevent inclination of the holder relative to a center axis of the outer member of the joint.

Sliding universal joint having a holder inclination restriction flange

A restriction flange is independently formed and then fitted on one end of each cylindrical holder in a sliding universal joint and abuts a rail portion surface of the transmitting groove to prevent inclination of the holder. The rail portion can also be formed independently of the outer member and then fixed thereto by bolting, welding or caulking.

A restriction flange is provided on the inner end of each cylindrical holder in a sliding universal joint to keep the pair of cutouts which are provided for installation of the inner roller aligned with the longitudinal direction of the transmitting groove. The flange can be rectangular having appropriate side lengths to restrict any rotational motion of the cylindrical about it's center axis.

Sliding universal joint having cylindrical holder positioning means

A stopper is slidably mounted on a bearing surface on the end wall of the inner member accommodating chamber of the outer member of a sliding-type universal joint. The bearing surface can be provided on a raised portion of the end wall larger in diameter than the diameter of a flange provided on the base of the stopper. The bearing surface is perpendicular to the axis of the outer member. A retainer in the form of a cylindrical member can be fitted to the outer periphery of the raised portion and can have an engagement portion to engage the flange of the stopper while allowing radial play of the stopper.

Stopper apparatus for inner member in sliding universal joints

In a slide type universal joint mounted between two transmission shafts between which power is transmitted, to connect both the shafts in a pivotable manner, a plurality of axially extending transmission grooves are provided in an inner peripheral surface of a hollow cylindrical outer member connected to one of the transmission shafts, while radial trunnions are mounted on an inner member connected to the other transmission shaft to project into the corresponding transmission grooves of the outer member. An inner roller is slidably fitted on the outer periphery of the trunnion and in turn, a holder is fitted on the outer periphery of the inner roller for rotatable support of an outer roller which is rollable within the transmission grooves. A regulating mechanism is provided between the holder and the outer member for preventing inclination of the holder with respect to the transmission groove while permitting smooth rolling movement of the outer roller within the transmission groove.
