The present invention relates to a method for controlling a suspension system of a motor vehicle comprising a vehicle body and a plurality of wheel pairs (2a/2b, 2c/2d), wherein the suspension system comprises spring members arranged for resilient connection between the wheels of the vehicle and said vehicle body. The method comprises the step of: monitoring at least one first parameter indicating braking of thee motor vehicle, and when said parameter indicates braking of the motor vehicle, preventing compression of the spring members of at least one wheel pair (2a/2b, 2c/2d) of the motor vehicle for counteracting a rotation of the vehicle body in connection to braking.

Provided is a linear motion mechanism having a further enhanced strength of a structure.

The linear motion mechanism including an intermediate link including a conversion mechanism that converts a rotational force from a motor into a driving force in a linear direction, the intermediate link extending in the linear direction, a first link that linearly moves toward a first side in the linear direction from an end of the intermediate link on the first side on the basis of the driving force in the linear direction, and a second link that linearly moves toward a second side opposite to the first side from an end of the intermediate link on the second side on the basis of the driving force in the linear direction, in which the first link and the second link linearly move symmetrically in the linear direction in conjunction with each other.

A tubular spring, such as a coil spring, a torsion-rod spring, and/or a stabilizer for motor vehicles, may comprise at least one metal tube element having a tube internal cross section, a tube internal diameter, a tube external diameter, a tube internal wall, and a tube wall thickness. At least one metal foam may be disposed in the tube internal cross section of the at least one metal tube element of the tubular spring in at least one part-region. The metal foam may be connected in an at least partially materially integral manner to the tube internal wall of the metal tube element. Further, the at least one metal tube element may have an at least partially martensitic structure.

A strut assembly for a suspension corner employed in a vehicle having a vehicle body and a road wheel includes a damper. The strut assembly also includes an elastic unit having at least one spring module acting in concert with the damper to suspend the vehicle body relative to the road wheel. Each spring module has a positive stiffness spring arranged in parallel with a negative stiffness spring. A vehicle that has a suspension corner employing the elastic unit and is configured to maintain contact between the road wheel and the road surface and provide isolation of vibration between the road wheel and the vehicle body is also contemplated.

The present disclosure relates to a swing arm assembly (1) for a mid-wheel drive wheelchair (21), comprising: a front swing arm (3) having a front swing arm pivot point (3a), a drive assembly swing arm (5) having a drive assembly swing arm pivot point (5a) and a resilient member first mounting point (5b), a rear swing arm (7) having a rear swing arm pivot point (7a) and a resilient member second mounting point (7b), and a resilient member (9) configured to be connected to the resilient member first mounting point (5a) and to the resilient member second mounting point (7a) to enable force transfer between the drive assembly swing arm (5) and the rear swing arm (7).

A vehicle includes a vehicle body having a structure and a wheel maintaining contact with a road surface. A suspension supports the structure and includes one or more suspension corner assemblies connecting the wheel to the structure and configured to maintain contact between the wheel and the road surface.
