Abstract: The invention relates to a gearwheel (1, 11, 31) with a three-part structure consisting of an outer toothed rim (2), a connecting element (3), and a hub element (4). The outer toothed rim (2) has a plurality of teeth (5) and is made of a plastic material injection-molded onto an outer edge (16) of the connecting element (3). The connecting element (3) has a central through-going opening (7) and the hub element (4) is arranged in the said through-going opening (7). To enable a lighter and/or inexpensive structure, the gearwheel (1, 11, 31) is characterized in that the thickness of the connecting element (3) is less than that of the hub element (4), and the connecting element (3) has a plurality of reinforcing structures (17, 24).

Abstract: A leaf spring device (1) for a vehicle having a first spring leaf (2) made of a fiber reinforced plastic and at least one further spring leaf (3). The first spring leaf (2) and the further spring leaf (3) interact with one another to implement a progressive suspension. The first spring leaf (2) has a receiving space (4) and the further spring leaf (3) is arranged in the receiving space (4) so as to implement the progressive suspension and/or to increase stability when using such a leaf-spring device (1).

Abstract: A gear arrangement is provided with a built-up for a shaft or pinion to rotate in unison therewith. The gear includes a gear rim and two flanges arranged axially on both sides and fixed them against the gear rim in a positive-locking connection. A hub, over which the respective other parts of the gear are pushed, is formed on at least one of the parts of the gear. The parts of the gear are held together without the use of rivets or screws by a clamped connection including a clamping ring, which is caused to mesh with a groove extending circumferentially on the circumference of the hub or shaft. The clamped connection presses the respective flange outer surface in a spring-mounted manner. Mutually corresponding elevations and depressions on the axial outer surfaces of the gear rim as well as on the axially inner surfaces of the flanges mesh with one another.

Abstract: A spiral-toothed gear wheel for a rack and pinion steering. The spiral-toothed gear wheel includes a pinion, which meshes on the power take-off side with a toothed rack, and a spiral-toothed gear, which is arranged on the pinion on the drive side in such a way that they rotate in unison, and on which a torque caused by a steering power or/and steering assist power acts. The spiral-toothed gear is designed as a built-up gear and includes a gear rim, which is arranged, relative to the axial direction of the gear or of the pinion thereof, between two flanges. The gear rim is pushed over a hub formed at one of the flanges and is fitted together with the flanges in a positive-locking manner. One of the flanges, namely, the flange having the hub for the gear rim, is made in one piece with the pinion.

Abstract: The invention relates to a skew gear constructed as a built skew gear and provided with attenuation. The skew gear wheel has a first flange for rotation-locked arrangement of the skew gear on a shaft or a pinion, a second flange or a disk, and a ring gear arranged and rotatable therebetween. The two flanges, or the first flange and the disk, are frictionally or positively connected with one another, wherein their respective elements providing the connection extend through the ring gear in the axial direction. According to the invention, at least one elastomeric element is overmolded on an inside contour of the ring gear for forming the attenuation, so that the ring gear and the attenuation form a single unit.

Abstract: A spiral-toothed gear is provided with a toothed ring (2) formed by extrusion coating a basic body (1) with a plastic. The spiral-toothed gear provides a connection between the basic body (1) and the toothed ring (2), whose strength makes possible the transmission of high torques in a reliable manner. The basic body (1) of the spiral-toothed gear has a flange with a disk-shaped area (1?) that is extrusion coated with the plastic toothed ring (2). The area (1?) of reduced diameter adjoining area (1?) forms a hub for mounting the spiral-toothed gear on a shaft in such a way that it rotates in unison. The area (1?) of the flange has, axially on both sides, a plurality of recesses (3, 3?) each, which are arranged distributed on its circumference, extend primarily in the axial direction but do not pass through area (1?).
