The present invention relates to a multi-part rail wheel with a wheel tyre, a wheel body, an elastic body arranged between the wheel tyre and the wheel body and via which the wheel tyre is supported on the wheel body, and at least one clamping element attached to the wheel body from one end face, via which the elastic body is braced against the wheel body and the wheel tyre by clamping means acting on the wheel body, the wheel body consisting of a light metal material in the region where the clamping means act. The rail wheel guarantees secure bracing of the components with simple assembly and disassembly. This is achieved by at least one counter-bearing element being provided on the end face of the wheel body opposite the clamping element. The counter-bearing element consists of a material which has a higher strength than the wheel body material.

A magnetic wheel includes: a balance block; a magnetic body which is provided in the balance block and attaches the balance block to an attachment object with a magnetic force; and a magnetic shielding block which is provided in the balance block and guides a magnetic field generated in the magnetic body toward the attachment object.

A wheel of a vehicle, in particular a motor vehicle, has a rim, a hub portion, and at least two spokes connecting the hub portion to the rim. At least one free space between the spokes is covered at least in part by a substantially planar covering element. The covering element is produced from two different material layers.

An attachment is provided for a vehicle wheel for enabling a driving operation with restricted tire functions. A system includes the attachment and a rim of a vehicle wheel.

A caster mounting portion has a mounting member housing portion which houses the mounting member, the mounting member has a rotary shaft portion which is pivotally supported in a bearing recessed portion in the mounting member housing portion, an abutment body in which the rotary shaft portion is provided at an eccentric position and which is displaced by rotation to be widened to close the inside of the mounting member housing portion, an upper locking piece which engages with a locking receiving portion of an opposed wall, a lower locking piece which abuts against the bottom face of a latching portion, and a locking stepped portion which is urged by a leading end of an elastic arm, climbing over the aforementioned latching portion, and engages with the latching portion.

A snap lock device for securing a wheel assembly to an axle is provided. The snap lock device may be formed from one integral piece. The snap lock device may include a hubcap and a first and second clip extending from the hubcap. The first and second clips may include a spring, an engagement member, and an actuator. The spring may be directly coupled to the hubcap. The snap lock device may be installed in the wheel assembly by inserting the cap assembly in the wheel assembly such that the first and second clip are placed in two apertures of a wheel and the springs bias the engagement members toward a center of a bore defined in the wheel for receiving the axle. The snap lock device can allow for tool-less installation and removal of the axle.

A track widening system for motor vehicles, having at least one track widening disc and at least one centering ring, which is inserted into a central opening of the track widening disc, wherein the centering ring has at least one catch device which is arranged at the free end of a resilient arm and wherein the track widening disc has at least one corresponding catch device. The centering ring may be plastic, and may be fiber-reinforced. One or more centering rings may have different colors.

Disclosed are modular mechanical assemblies formed from durable, corrosion resistant components with sufficient strength to maintain efficient operation. The modular mechanical assemblies include a novel torsion axle assembly having a cartridge that houses a torsion bar with a splined tip. A load bearing, relatively incompressible bushing is optionally disposed about the torsion bar. The cartridge is inserted into an axle tube, and an end cap is placed over the cartridge and torsion bar. The end cap is affixed to the axle tube such that the bushing is secured within a bore in the end cap. The torsion bar tip extends through the bushing and end cap and is secured within a torsion arm. A spindle is also secured within the torsion arm. One or more components of the torsion axle assembly are made from a low alloy, medium carbon steel material that provides corrosion resistance and advantageous yield and ultimate strength properties. One or more components of the assembly can also be coated to improve corrosion resistance. Suitable coating techniques include, but are not limited to liquid ferritic nitrocarburizing, gas nitriding, electroless nickel plating, or a diamond like carbon coating process.

A wheel axle for a vehicle, having a shaft extending along a main axis, a first protection device and at least one second protection device, each device having a body at least partially surrounding the shaft in a plane perpendicular to the main axis, the body having a first end portion and a second end portion, the end portions being opposite one another along their main axis. The first end portion of the first device at least partially surrounds the second end portion of the second device in a plane perpendicular to the main axis.

Self-locking nipple for attaching wheel spoke to wheel part. The self-locking function of the nipple is created by deforming the nipple body in a rotationally symmetrical way and over a predetermined axial distance, such that such a narrowed part is created in the internal screw-thread of the nipple which is rotationally symmetric with respect to the longitudinal axis of the nipple and extends over only one to two windings of the internal screw-thread.
