Abstract: A progressive gear assembly that is a vehicle steering gear, the assembly comprising at least one spur gear (1, 2) and a toothed structure (3, 4, 5, 7, 8) with which the spur gear (1, 2) meshes. The spur gear (1, 2) has teeth (11) arranged along a curve (10), the curve (10) comprising a radius of curvature (r) which monotonically rises over an angular range of more than 90° of the curve (10). Preferably the curve is a spiral, particularly a logarithmic spiral. This gear assembly is configured compact and simple, features smooth running and achieves a late end point.

Abstract: The invention relates to a transmission mechanism (20) of a progressive gear (1), especially a steering gear for a vehicle, comprising a seating for each of an input shaft (10) and an output shaft (30). The transmission mechanism (20) according to the invention consists of a movable coupler (21) which is in articulated connection with the input shaft (10) and the output shaft (30) so that transmission from the input shaft (10) to the output shaft (30) with a progressive characteristic is achieved in the range ?180° to +180°. The advantage of such a gear (1) lies in the simple and therefore economical production of the apparatus and in its low space requirement. The absence of play in the mechanism and the direct transmission of forces by virtue of the individual components having suitable angles with respect to one another are further advantages.

Abstract: The invention relates to a translation mechanism (20) on a progressive gear (1), preferably a steering gear on a vehicle, with an input shaft (10) and an output shaft (30). Said translation mechanism (20) comprises three moving parts (21, 23), which are jointed together and fixed to levers (11, 31) on the input shaft (10) and the output shaft (30), such that a translation with a linear progression in the range ?180° to +180° is achieved from the input shaft (11) to the output shaft (30). The advantage of a said translation mechanism (20) lies in the lack of play in the mechanism and the direct force transfer due to the suitable relative angles of the individual components and the economical production thereof.

Abstract: The invention relates to a tensioning/relaxing element that comprises a base (3), at least one rotating shaft (4) mounted on said base, a mobile part (2) and a lashing device (1). Between said base (3) and the at least one shaft (4) at least one nonpositive and positive element (5, 6) is provided that tightly encloses the shaft (4). The first nonpositive and positive element (5), configured as a tensioning element, is firmly linked on the one side (5a) with a part (2) that is mobile vis-a-vis the base (3) and can be actuated on the other side (5b), with a variable and continuous pretension, via a first actuator (11), while the second nonpositive and positive element (6), configured as a relaxing element, is firmly linked on the one side (6a) with the base (3) and can be actuated on the other side (6b), with a variable and continuous pretension, via a second actuator (11′).
