The invention relates to the load regulation of an air suspension vehicle braking system.

Typical embodiments are load regulation with air springs on only one side of the rear axle. Pressure v. the number of them changes when cornering, and when braking in the jetaom direction of rotation, the axle brakes more than when driving straight and in the opposite direction brakes the man · r ·

in.

Also known is an embodiment where the pressures of the air springs of both. On the sides of the axle, they separate the two active surfaces of the components! This embodiment has a greater passive resistance due to the sealing of the two active surfaces. Even the average pressure signal is not ideal for load regulation, as the axle has less braking power and less braking power to transmit side forces.

These disadvantages are overcome by the braking control arrangement according to the invention, which is based on the fact that the air springs on both sides of the axle are interconnected by piping with the inlet throats of the lower pressure member, from whose outlet throat

This design achieves a braking effect independent of the direction of rotation. Of the two different thicknesses on the left and right side of the vehicle, a lower pressure is always used to control the load control of the braking. This achieves the desired reduction in cornering performance.

Examples zapooení are shown in FIGS · 1 and 2, wherein Fig. 1 shows a general diagram zapojeiní brake control, and Fig. ¹ two embodiments, in which like member during limited 0 (^ 0 ^ 101 a lower pressure controller is used verti! (Relay Venn! ).

In Fig. 1, the air springs 4 and 2 of both sides of the axle are connected by piping. 2 and 6 with the inlet orifices 0 and N of the lower pressure relief member 6. In FIG. 2, a known control valve (relay valve) is connected as a lower pressure exiting member. 2 and 6 with its control 0 and supply N throat.

The connection according to the invention works as follows: The latex in the left air spring 4 and in the right air spring 2 is generally different, especially when cornering or on a transverse slope. The lower pressure producing member 6 permits into its outlet throat. Only the lower of the inlet pressures. From there, the compressed air is discharged via line 6 to the load control braking system. .

Since the transmission of the lateral force through the axle which consumes part of the adhesion is always accompanied by a pressure drop in the air springs of one side of the vehicle, a desirable reduction in the braking effect is achieved.
