A method for detecting and estimating an angle of rotation on itself, about a mounting axis, of a wheel unit with an acceleration sensor, the wheel unit being associated with a tire mounted on a rim, forming a wheel, the sensor detecting a gravitational force during the rotation of the wheel, forming a sinusoid. The wheel unit is mounted on the wheel with the acceleration sensor directly or indirectly inclined with respect to a plane tangential to the rim. The angle of rotation on itself of said wheel unit and therefore of the acceleration sensor at a given instant is estimated by comparing at least one parameter of the sinusoids that are obtained for the wheel unit in an initial mounting position on the wheel and in its position at this given instant, respectively.

A child vehicle includes a front frame having a handlebar with a steering tube and a front fork having a fork stem and a front wheel, a rear frame including a head tube and a rear wheel, and a sleeve assembly mounted to the front frame and engaging the rear frame to rotatably connect the front and rear frames in a tool-less manner. A method of tool-less assembly of a child vehicle includes inserting an end of the fork stem through the head tube, sliding an inner sleeve over the end of the fork stem and positively connecting the inner sleeve to the fork stem, sliding the outer sleeve over an end of the steering tube, connecting the steering tube to the fork stem, and connecting the outer sleeve to the inner sleeve. A child vehicle having a rear wheel connected to the vehicle in a tool-less manner and a method of achieving such a tool-less connection is also disclosed.

An axle for a vehicle, wherein the axle includes a transverse axle portion having a longitudinal end. The axle including a first axle portion connecting the transverse portion to a chassis of the vehicle and a second axle portion connecting the transverse portion to a wheel carrier for supporting a vehicle wheel. A vibration damper is arranged in a receiver in one of the axle portions.

A drive axle for a work machine for driving wheels that are coupled to the drive axle. The drive axle includes a spur gear stage with an input shaft. A differential gear unit couples to the spur gear stage and to the wheels via wheel drive shafts. The drive axle further includes a reduction gear unit with an output element couples to the input shaft of the spur gear stageand an input element which couples to an output shaft of an electric drive machine.
