Abstract: A propeller shaft for a vehicle in which a tube yoke is connected to a main tube via an adapter and tapered splines are formed at the contact regions between a tube yoke and the main tube to transmit the power output from a transmission to a rear wheel. The tube yoke and the main tube are displaced relative to each other at the tapered splines to break the adapter. The tube yoke and the main tube are thus separated from each other by virtue of the breakage of the adapter.

Abstract: Briefly, implementations of claimed subject matter relate to methods and devices for coupling a first rotating shaft to a second shaft. In a particular implementation, an end of a plurality of resilient fingers of a resilient structure may be radially displaced to permit positioning of the resilient structure over a first shaft.

The connecting element comprises a connecting portion with an outer toothing which is pressed with a press fit into a connecting portion of the shaft tube so that an interlocking connection effective in the circumferential direction is formed for torque transmission, wherein the connecting element comprises a maximum outer diameter in the region of the outer toothing; wherein the shaft tube comprises an axial connecting region which is formed radially inwardly into a section of the connecting portion that is reduced relative to the outer toothing so that an interlocking axial connection effective in the axial direction is formed between the shaft tube and the connecting element for transmitting axial forces. A drive shaft can have such a shaft connection.

Abstract: The invention pertains to a portable fencing system that provides for easy and versatile positioning and removal. In one aspect, the portable fencing system includes sleeves that are pre-positioned in the ground so as to define a predetermined boundary suitable for a particular repetitive use. In another aspect, a portable fencing system that is without pre-positioned sleeves is described, which is more suitable for applications where the insertion of semi-permanent sleeves is impracticable, or where added positioning flexibility is desired.

Abstract: A low surface-roughness part is formed at a first tapered part, as a result, the roughness of an opening-edge of a groove part of an internal spline part that opens at the first tapered part is reduced, and surface pressure applied by the opening edge to a tooth of an external spline part can be reduced. As a result, the opening edge of the groove part of the internal spline part can be kept from digging into the tooth, and variation, between products, in the insertion load of a second shaft part can be suppressed.

The curved surface portion can extend over the entire surface of a groove, for example. The other component has a taper. When assembling the two components before a force is applied, a line connection is created from the 2-contact point connection and when force is applied, the line connection changes through plastic deformation into a strip connection, on the basis of which the two components (1, 2) hold together.

Abstract: A mechanical sliding connector that mates to an identical mechanical connector by a sliding action. The connector can be slid into another connector or another connecter can slide on to it, allowing the connectors to connect in either direction. The connector features a latching mechanism that engages with no interaction required by the operator other than sliding the connectors together. Unlatching the connectors can be accomplished by unlatching either of the connectors and sliding them apart. The connector latch resets automatically after it's disconnected enabling it to be ready for another connection without user action. This feature along with a latch locking feature provides for easy one hand operation.
