The disclosure relates to an electric power steering system having a rack for steering wheels of a vehicle and having a pinion shaft. The pinion shaft meshes with a row of teeth of the rack in an assembled state. The rack has an assembly portion for an initial assembly of the pinion shaft, with one end of the row of teeth transitioning into the assembly portion. On the one hand, to facilitate initial assembly for establishing a connection between the pinion shaft and the row of teeth of the rack and, on the other hand, to prevent the connection between the pinion shaft and the row of teeth of the rack from breaking during repair measures carried out after the initial assembly, the electric power steering system is arranged such that first teeth of the row of teeth each have a first tooth height and the assembly portion has second teeth for interacting with the pinion shaft, the second teeth each having a second tooth height that is less than the first tooth height.

To securely and easily disassemble and assemble a rack gear and a pinion gear. A drive mechanism 5 includes a rack gear 5A, a pinion gear 5B engaging with the rack gear 5A, a positioning member 5D fixed to a portion in the rack gear 5A where rack teeth 5Ab are not included, and a plurality of abutting members 5E disposed along a rotation direction of the pinion gear 5B. In a case in which at least one of the rack gear 5A and the pinion gear 5B is moved in a relative movement direction at the time when the rack gear 5A engages with the pinion gear 5B, abutment between the positioning member 5D and the abutting member 5E defines a rotational position of pinion teeth 5Bb of the pinion gear 5B to be an engaging position with the rack teeth 5Ab of the rack gear 5A.

A rack for a steering gear of a motor vehicle may include a toothed portion having a toothing, and a shaft portion. Separate segments comprising at least one in each case bar-shaped toothed segment and one shaft segment are provided, are aligned on a common longitudinal axis, and are connected to one another at a joint. The method may involve providing a raw material piece having a piece length that is a multiple of a segment length, thermally continuously hardening the raw material piece across a multiple of a segment length to produce a hardened semi-finished segment product, cutting to length a hardened segment from the hardened semi-finished segment product, providing a further segment, and joining the hardened segment to a further segment.

An anchor for a support member of a track system may include an anchor body and a toothed anchor portion. The anchor body may be connectable to said support member. The toothed anchor portion may include a plurality of anchor teeth configured to engage a plurality of track teeth of a toothed portion of a track assembly. The anchor body and the toothed anchor portion may be connected to one another to collectively form a hook portion configured to engage said toothed portion of said track assembly. At least a subset of anchor teeth of the plurality of anchor teeth may be disposed one after another in a curved or angled configuration to define a curved or angled row of anchor teeth.

The rack housing has an engaging concave section having a bottom surface configured by a bottom inclined surface that is inclined in a direction outward in the radial direction toward the opening side of the rack housing, and the rack bush comprises an engaging convex section having a top surface configured by a top inclined surface that is inclined in a direction outward in the radial direction toward the opening side of the rack housing. The top inclined surface is pressed against the bottom inclined surface toward outside in the radial direction, and the outside surface of the engaging convex section facing the opening side of the rack housing is pressed against the inner side surface of the engaging concave section facing the inner side of the rack housing.

Convertible multifunctional furniture comprising at least one support base, at least one lifting device which is supported on the support base, a usage unit, a horizontal rotational axis in the longitudinal or transverse direction about which the usage unit can be rotated, and a mounting pin at each end of the rotational axis. At least one scissor mechanism is arranged between the lifting devices and each mounting pin of the rotational axis, at least one scissor limb is connected to a drive of the lifting device at one end and to a support at the other end. The other end of the scissor both is connected to a linear element for controlling purposes, said linear element having a surface which can be coupled to a surface of a wheel that is rotatably coupled to a complementary element of the mounting pin.

A steering device includes a rack housing portion housing a rack shaft, a pinion gear provided on one end side of the rack housing portion, a first supporting portion provided on the rack housing portion to support the one end side of the rack housing portion, and a second supporting portion provided on the rack housing portion to support the other end side of the rack housing portion. The second supporting portion includes a first vehicle body mounting portion and a second vehicle body mounting portion provided to project outwardly of the rack housing portion, the first and second vehicle body mounting portions being mounted on a vehicle body. The first and second vehicle body mounting portions are arranged to be shifted in an axial direction of the rack housing portion so as not to overlap in the axial direction.
