Embodiments of the invention are directed to an upper ball joint assembly for connecting an upper axle housing to a steering knuckle of a vehicle. In one embodiment, the upper ball joint assembly comprises a plurality of components including a tapered ball joint pin (or stud), a ball joint cup and a threaded cap configured to assemble together into an upper ball joint assembly. In an assembled configuration, a proximal, or head component, of the ball joint pin may be housed within one or more chambers (or tiers) of the ball joint cup. The cap may reversibly engage with the ball joint cup to complete the assembly. The ball joint assembly may have a hardness characteristic of between forty (40) and one-hundred (100) Rockwell.

The invention provides a ball head joint finger mechanism with flexible connection and hydraulic drive. The ball head joint finger mechanism includes a three-rod two-joint mechanism, a hydraulically driven locking mechanism and a flexible connection mechanism; the three-rod two-joint mechanism includes a first ball head rod, a second ball head rod and a ball socket rod; a ball socket A and a ballsocket B are separately disposed at the two ends of the ball socket rod; the ball socket rod is provided with a ball socket rod through hole along the axis; the flexible connection mechanism includesa first flexible connecting piece and a second flexible connecting piece; the ball head end of the first ball head rod can be matched with the ball socket A and the ball head end of the first ball head rod and the ball socket A are connected through the first flexible connecting piece to form a first ball joint, and the ball head end of the second ball head rod can be matched with the ball socketB and the ball head end of the second ball head rod and the ball socket B are connected through the second flexible connecting piece to form a second ball joint; and the hydraulically driven locking mechanism is disposed in the ball socket rod through hole, and includes a first piston, a second piston and an oil chamber formed between the first piston and the second piston. The ball head joint finger mechanism has the characteristics of combining flexibility and rigidity, the structure is compact, the output force is larger than that under the condition of volume, the action is flexible, and manufacturability is high.
