Description

Rear axle for motor vehicles with pendulum half axles All known so far Constructions of rigid and pendulum axles have the disadvantage that the shocks that has to pick up the bike from the road, directly via the spring or another Spring element to the chassis or the self-supporting body in more or be passed on in a less strong form. This is particularly effective on bumpy roads or hard suspension very annoying to the car occupants and puts them in such Falls into a not exactly pleasant swing in the seats. Another disadvantage of these constructions is the dwindling grip, whether wavy or sideways depending roads are run over. A precise control in the control of the Motor vehicle or sufficient braking effect are no longer in most cases given.

There are also constructions known in which an inherently rigid Axle bracket is fastened over the pendulum half-axles, the ends of which extend over coil springs support against the pendulum half-axles. Here is a good road holding and a Safe driving of the vehicle sought, but because of the high altitude required Center of gravity of the body and the slight sideways swing not reached.

According to the invention, these problems are now solved in such a way that the spring is not fastened between the axle and the chassis as before, but a specially shaped bracket is used as an intermediate transfer element. Of the Bracket is attached in such a way that impacts which on one or the other half of the axle of be carried out on the road, taken up by the correspondingly assigned spring and via the bracket and the spring assigned to the other half of the axle to the other Half of the axle are forwarded, d. This means that the shock compensation takes place only via the Bracket and the axle halves. The one described, about the bracket and the axle halves the impact compensation also causes the good grip mentioned at the beginning; so always safe road holding.

Because the swivel mounting of the bracket is below the for both pendulum half-axes common journal bearing takes place, the focus of the structure can be placed very low will. In addition, the support of the body is above the axle and bracket pivot points; thus in a zone which is at the intersection of the balance between left and right lies. The body is therefore always in the balanced central position and thus in the desired state of suspension.

To allow the body to swing sideways or to move out of the To prevent central position to the axes, on each side are self-resilient Connections provided, which still have the advantages shown according to the invention raise. In particular, this improves driving safety on bad roads or increased even at high speed.

In the above-mentioned, inherently resilient connections, the spring travel is limited. The limitation corresponds to the maximum difference that occurs during the process the axle suspension through the different radii of motion of the two with each other working parts can arise.

The invention is shown schematically in the drawing. When driving over a bump, z. B. by the left wheel, the pendulum suspended left axle half 1 is pushed upwards. This pressure (shock) is partially absorbed by spring 2, but at the same time transferred via bracket 3, which rotates at bearing point 4, to spring 5 and thus again cushioned to the right axle half 6 and thus to the right wheel.

The structure 7 of the carriage is above the pivot point of the bracket on the Housing of differential gear attached.

The resilient, telescopically acting connections 8 and 9 between the semi-axes 1 and 6 and the bracket 3 have the task of a lateral Prevent shifting the semi-axes to the body.
