Abstract: A linear roller bearing element with an endless rolling element channel is composed of a carrier raceway for the load-bearing rolling elements on a carrier body, a return channel for rolling elements that are returning, and turnaround channels that connect the carrier raceway and the return channel at both ends with each other in an endless manner, the turnaround channels being bounded by end covers. The roller bearing element has two rolling element channels with two longitudinally extending carrier raceways located next to each other within a common plane and with clearance between them, on the carrier body for load-bearing rolling elements, and two assigned return channels for rolling elements that are returning, and respective turnaround channels. With a linear roller bearing guide, these roller bearing elements are located between a guide rail and a guide carriage—which is supported such that it is displaceable relative to the guide rail—in order to provide support.

Abstract: An actuating device for a transmission of a vehicle, particularly a commercial vehicle, a bus, or the like, moves a trip cam of the transmission forward or backward in the longitudinal direction, and in the transverse direction in one direction or the other transversely to the longitudinal direction. It has a spindle, which includes two axially adjacent thread sections with opposing thread directions, with a spindle nut on each thread section of the spindle, with a drive motor for each spindle nut to drive it in a rotary manner, and with a coupling member that engages with the trip cam and moves it in the longitudinal and transverse directions, and which is actuatable using the spindle.

Abstract: A linear roller bearing has raceway elements, which are grouped around the central axis of the bearing, include rows of rolling elements distributed around a circle—as viewed in the cross section—and which are essentially parallel to each other and to the central axis of the bearing, the raceway elements being by enclosed in the circumferential direction by at least one connecting piece on at least one longitudinal section such that the raceway elements bear via the outer surface of the longitudinal section against a facing inner surface of the at least one connecting piece. The inner surface and the outer surface are curved biaxially and bear against each other in two dimensions, thereby resulting in a design similar to that of a ball joint.

Abstract: A double piston for a compressor, having an elongated piston carrier which has one piston on each end, and having a connecting rod, extending approximately parallel to the piston carrier, that is supported rotatably by means of a bearing on a bolt of the piston carrier and spaced apart from it is supportable on a cam of a drive mechanism by means of a connecting rod bearing. In a middle region that extends between the two pistons, the piston carrier includes an intermediate chamber, dimensioned to receive the connecting rod freely movably, in which the connecting rod is received freely movably.

Abstract: A connecting rod for a piston of a compressor for a double piston has a portion supportable by a connecting rod bearing on an eccentric of a drive device, a coupling point at a distance from the portion for connecting with the piston, and at least one vibration damping device which in a course of the connecting rod is arranged between the connecting rod bearing and the coupling point.
