An independent wheel suspension system having a transverse support member attached between the side frame members of a vehicle frame, a semi-trailing arm having a wheel end coupled to the wheel assembly and a pair of spaced-apart support sections pivotably coupled to the transverse support member, a differential rotatably coupled to the transverse support member to allow relative movement therebetween about a transverse pivot axis, and a prop shaft coupling the differential and engine with only one universal joint, that joint being of the constant velocity plunging type, whereby the differential is allowed to pivot about the transverse pivot axis to accommodate articulation between the prop shaft and the engine.

A constant velocity torque transmitting universal joint, utilizing spherical ball members arranged in a longitudinal groove of an inner joint member, is adapted to connect to a shaft and a longitudinal groove of an outer joint member. The outer joint member is connected to a second shaft so that the outer joint member may be displaced in an axial direction relative to the inner joint member. Therefore, the inner joint member may be displaced in an axial direction relative to the cage restraining member holding the spherical ball members in their mutually opposed grooves of their respective joint members. The cage restraining member permits the spherical ball members to roll in their respective grooves for a short distance prior to skidding to reduce the overall resistance to axial movement effort prior to skidding as a result of the friction torque relationship of the joint. This is accomplished by providing a relatively flat or cylindrical surface on the outer periphery of the inner body member for a relatively short axial portion and blending appropriate spherical radii with the surface in order to provide sufficient clearance between the inner joint member and the inner surface of the cage. By providing this relatively flat portion to the outer surface of the inner body member, the start of the displacement of the spherical ball members with respect to the outer joint member is considerably facilitated since the spherical ball members can roll in their respective longitudinal grooves prior to skidding.
摘要:
A method for making constant velocity joint cages involving a minimalization of offal, scrap, rework, production time and production costs. A sheet of flat metal stock is die-cut stamped or cut by laser into a circularly shaped multi-limbed member having a central circular aperture therein and truncated limb radials extending therefrom that end in a predetermined angle. The multi-limbed member is then pressed into a spherical shape, forming a half-cage member. This process is repeated to make a second half-cage member. The two half-cage members are then placed together with their radials aligned. The aligned radials form legs which thereby define windows on the cage. The half-cage members are then rotated relative to each other with the angle on each radial acting as a ramp that causes the window width to lengthen or shorten in response to rotation in a particular direction. In this way, the window width may be precisely set to specification. When the window width is set, the radials are welded together forming a constant velocity joint cage needing only heat treating, and minimal polishing and grinding. No further processing of the windows is necessary.

摘要:
A universal joint for transmitting driving torque between rotative members including an inner joint member for connection to one of the rotative members and an outer joint member for connection to the inner joint member and to the other of the rotative members. The inner joint member swivels within the outer joint member by virtue of contacting inner and outer spherical surface portions on the outer and inner joint members, respectively. Torque is transmitted between the inner and outer joint members by a plurality of roller balls which extend between a recess in the inner joint member and a plurality of circumferentially spaced-apart rectilinear recesses in the outer joint member which are disposed between the spherical inner surface portions on the outer joint member. The recess in the inner joint member permits the spherical roller balls to come into contact with one another, and the rectilinear recesses in the outer joint member permit the roller balls to separate when the inner and outer joint members articulate with respect to one another.
