Abstract
1511522 Braking control for tractor-trailer combinations DAIMLER-BENZ AG 21 July 1975 [22 July 1974] 30433/75 Heading F2F Apparatus for regulating the braking force on the wheels of a towing vehicle/trailer combination 10, 11, in which respective independently controllable anti-locking braking force control systems are provided for the towing vehicle and for the trailer, by means of which systems each individual wheel is controllable in the stable region of the co-efficient of friction-slip curve, comprises a measuring means 20 disposed in the connection (e.g. tow-bar 15) between the towing vehicle 10 and the trailer 11 to ascertain the force occurring in said connection, the measuring means 20 being connected to transmit a signal to the anti-locking braking force control system of the towing vehicle when a predetermined compressive force in said connection is exceeded, upward adjustment of the braking force on the towing vehicle being blocked at least for the duration of the signal. This ensures that as the combination passes from a length of road having a low coefficient of friction to a length of road having a high coefficient of friction, an upward adjustment of the braking force on the towing vehicle wheels is prevented to thereby prevent jack-knifing. As seen in Fig. 2 an electronic part 17 of the control system of the towing vehicle 10 converts signals from sensors 18 on the front axle 13 and rear axle 16 into switch pulses to control valves 19 to control the braking force; the trailer 11 has a similar braking force control system but the two systems are independent. A threshold switch 21 is associated with the measuring means 20 and supplies a digital output signal to part 17 when the predetermined compressive force is exceeded. In one embodiment the threshold switch is connected by way of a matching amplifier and a filter. The threshold switch may also operate a timing element the running time of which may be reduced with increasing vehicle road speed. If the arrangement is utilized with a semitrailer unit, static fifth-wheel and trailer axle pressures are additionally measured.
