Abstract
Abstract A front wheel suspension for motor vehicles with the use of a triangularly shaped guide member whose two guide arms are elastically supported at the vehicle superstructure in such a way that of the two guide arms, the forwardly disposed guide arm is directly elastically connected at the vehicle superstructure while the rear guide arm is connected with the vehicle superstructure by way of a cross yoke that is common to the wheel suspensions of both vehicle sides; the forward and rear guide arm of each triangular guide member are thereby pivotally connected with each other and a relatively radially soft bearing support is used for the forward guide arm at the vehicle superstructure; while the rear guide arm is pivotally connected at the cross yoke in such a manner that the connection of the rear guide arm with the cross yoke is constructed relatively hard at least in the direction of the line of force determined by its points of pivotal connection.
