A mobile robot (for example, a robot used for package deliveries, among other purposes) may include a mast with a visual indicator for providing visibility to drivers and pedestrians in the environment proximate to the mobile robot. The mast may produce a large moment arm, which may result in the mast being more likely to break off from the robot. To mitigate or prevent damage to any components of the mast and/or the mobile robot when such a breakage occurs, described herein is an omni directional breakage joint that is used to connect the mast to the mobile robot. The omni directional breakage joint comprises multiple ball and socket joints that provide structural support between the mast and the mobile robot, while simultaneously allowing for a certain movement freedom of the mast and allowing for the mast to easily be engaged and disengaged from the mobile robot without causing damage to any components.

A clamping mechanism embodying the invention may be disposed between a swivel ball and a housing overlying the ball for selectively locking or unlocking the swivel ball relative to the housing. The clamping mechanism includes first and second gears mounted on a compression screw with rotational forces being selectively applied to the first and second gears via respective first and second gear-pawl assemblies. The rotational forces cause vertical (up/down) motion along the screw which increases or decreases the pressure exerted between the housing and the swivel ball which effectively may be used to lock (clamp) or unlock (unclamp) the swivel ball relative to the housing.

The ball socket assembly includes a housing that is made of a monolithic piece which includes a lower wall. A ball portion of a ball stud is disposed in an inner bore of the housing. An exit bearing, which is made of a polymeric material, is disposed in the inner bore and is in slidable contact with at least one hemisphere of the ball portion. The exit bearing has an upper surface which faces towards an open end of the housing. A cover plate is in direct contact with the upper surface of the exit bearing along a surface-to-surface contact area. The surface-to-surface contact area is angled towards the open end from its radially outermost end to its radially innermost end for supporting the exit bearing against radial expansion in response to axial loads being applied on the exit bearing from the ball portion of the ball stud.

A connecting rod has a big end bearing eye for attachment to a crankshaft, a small end bearing eye for attachment to a piston of a cylinder, and an eccentric adjusting device for adjusting an effective connecting rod length. The eccentric adjusting device has eccentric rods (15, 16) with first ends that engage on an eccentric lever of the eccentric adjusting device and second ends that engage on pistons (20, 21) guided in hydraulic chambers of the connecting rod. The second ends of the eccentric rods (15, 16) are spherical heads that engage in a corresponding recess (40) in the respective piston (20, 21), and the respective piston (20, 21) further accommodates a retention element (41), one segment of which rests on the spherical-headed end of the respective eccentric rods (15, 16).

A ball joint has a dust cover fitted onto the outer periphery of a socket formed into the shape of a cylinder with a bottom. The socket has a dust cover groove into which a socket-fitting portion of the dust cover is fitted, and a dust cover-recieving surface for supporting a socket-facing surface of the dust cover. The dust cover-recieving surface inclines toward the socket-facing surface while extending from the outer side toward the inner side. Radial projections are formed on the inner peripheral surface of the socket-fitting portion of the dust cover. An axial projection which projects toward the dust cover-recieving surface is formed on the socket-facing surface of the dust cover.

A ball bearing including a ball head arranged at a support rod and supported in a ball head receiver, characterized in that the ball head is secured at an outer surface of the ball head in the ball head receiver by a retaining ring against sliding out of the ball head receiver. The invention also relates to a piston rod with the ball bearing.

The ball joint includes a housing and a stud with a spherical bearing surface disposed in the housing. The bearing has a concave spherical bearing surface which is brought into sliding abutment with the spherical bearing surface of the stud. The bearing is of a monolithic piece of fiber-reinforced polyamide material and includes carbon fibers which extend circumferentially about the concave spherical bearing surface.

A ball joint orientation device applicable to a unipod includes a ball joint and stop members, in which one end of the ball joint is formed as a rotating part and is arranged in a ball joint seat in a universal swaying manner, and the other end extends to form a connecting part and is fixedly connected with a main rod; the stop members are arranged in the ball joint seat, and include a locking stop member located at the upper side of the rotating part; an orientation knob is sleeved on the connecting part and/or the main rod; when screwed toward the direction close to the ball joint seat, the ball joint is subjected to orienting locking and no longer rotates; and when screwed toward the direction away from the ball joint seat, and the orienting locking is released, so the ball joint is rotatable freely.

A stabilizer link and a production method therefor are provided in which a jig for attaching a forming die to a subassembly has a simple structure and which can effectively prevent leakage of a resin to the outside. In insert molding, a ring member is used. An outer peripheral side surface of a ball seat of a subassembly is abutted to an inner peripheral surface of a hole of the ring member. An outer peripheral side radial direction surface of a fixing portion of a dust cover is pressed toward the flange portion of the ball seat by a surface of the ring member, and the fixing portion is held by the surface and the flange portion. An end portion of a die body is abutted to another surface of the ring member.
