Abstract: A chassis of a utility motor vehicle has a double wishbone suspension having two independent wheel suspensions, each wheel suspensions has an upper control arm, a lower control arm, and a wheel carrier. The upper control arm is connected to two upper connection points on the vehicle body which define a first axis, the upper control arm being rotatable relative to the vehicle body about the first axis, and the lower control arm being connected to two lower connection points on the vehicle body which define a second axis, the lower control arm being rotatable with respect to the vehicle body about the second axis. The first and second axes are parallel to one another and inclined relative to a horizontal by an inclination angle that is greater than 0° in a forward direction of travel when the double wishbone suspension is installed in the utility motor vehicle.

Abstract: A valve arrangement for a vibration damper, as may be used on a vehicle. The vibration damper can be a telescopic suspension fork leg of a motorbike, or a shock absorber for a vehicle with more than one track, for example an automobile. The valve arrangement is for a vibration damper that has a valve housing with an annular valve seat, and is configured to receive damping fluid, and further having a valve piston arranged in an axially displaceable manner relative to the valve seat in an inner space of the valve housing. The valve piston has a main valve which has a flexible circular valve disc which can be removed from contact with a contact surface side on the valve seat. The valve disc is arranged on the valve piston by a guide pin, such that it can be moved axially relative to the latter and is guided radially.

Abstract: An independent wheel suspension includes a knuckle which is supported on a spring support connected to a vehicle body. The knuckle is connected to the spring support via a knuckle pin and is arranged so as to be mounted rotatably around a longitudinal axis A of the knuckle pin. The transverse control arms are mounted at the upper end and lower end, respectively, of the knuckle pin. The spring support is connected to the knuckle pin so as to be fixed with respect to rotation relative to it so that the knuckle pin connects the spring support, the knuckle and the upper transverse control arm and lower transverse control arm together. The independent wheel suspension has a further safety component which prevents the knuckle pin from rotating in an uncontrolled manner around its longitudinal axis A.

Abstract: A telescopic suspension fork leg, such as may be using in conjunction with a motorcycle. The fork leg has an inner tube and an outer tube, a damping arrangement, and a spring arrangement which is arranged inside a first chamber formed in the outer tube and resting opposite a second chamber formed by the damping arrangement and arranged beneath the first chamber. The telescopic suspension fork leg features a compressible equalizing volume for a damping fluid volume displaced by a piston rod. The equalizing volume is provided generally concentrically between a damping tube and a separating piston. The separating piston fluidically separates the equalizing volume from an annular space chamber.

Abstract: An elongated concrete structure, such as a bridge, is constructed by providing at a construction zone located at one end of the site of the structure a formwork arrangement which includes a bottom formwork within which the structure may be formed in discrete sections. Successive discrete sections formed in the formwork are joined together and launched in series from the construction zone toward the opposite end of the site across which the structure is to extend. As each section of the structure is launched, the bottom formwork is moved together with each section across one section length in the launching direction while the remainder of the formwork arrangement is maintained stationary at the construction zone.
