Hydraulic installation for heavy vehicle - has magnetic valve blocking or opening by=pass to regulate rear wheel braking effort according to load

The heavy vehicle has separate front and rear wheel brake circuits and an ABS control. The rear wheel brakes (13,14) are linked to the brake system by proportional control valves (31,32) which provide an increasing brake force with increasing rear axle loads. These valves are bridged by the ABS control valves (43,44) which prevent rear wheel locking. For normal operation the increasing loading results in increasing brake effect from the rear wheels. This relieves the front wheel brakes from excessive braking effort. If the rear wheel brakes start to lock, the normal ABS system protects the vehicle. The load regulators are mounted near the rear suspension, as are the proportional valves. ADVANTAGE - Less brake wear (front); improved braking balance for heavy loads.

SCHALTUNGSANORDNUNG FUER EIN ANTRIEBSSCHLUPFREGELUNGSSYSTEM MIT BREMSEN- UND/ODER MOTOREINGRIFF

A circuit arrangement for a drive slip control system assesses the speed (vER) measured at a driven spare wheel with a correction factor K(t) in order to maintain or improve the control function even when a smaller spare wheel is fitted. This correction factor (K(t)) is found with the drive slip control inoperative by the comparison between axles of the rotation speeds (vna1, vna2, va, vER) of the wheels on one axle and the comparison of the rotation speed differences measured on the driven and undriven axles. On the transition from very slippery road surfaces ( mu lowuniform) to dry ones ( mu highuniform) without the prior calculation of the correction factor, the slip threshold (S) is temporarily raised. When running on different friction factors on the right and left ( mu -split), a raised slip threshold (SER) becomes effective on the spare wheel if it is fitted on the high-friction factor side.

MOTORANTRIEBSSTEUEREINHEIT

Ein Erhöhen des Startstroms, der einem Motor zugeführt wird, wird in einem Anfangsstadium des Startens der automatischen Bremssteuerung unterdrückt, während die Stromzuführung zum Motor in einem vollständig erregten Zustand ausgeführt wird, nachdem die automatische Bremssteuerung gestartet wurde. Während die Ausgabe des Motors durch Steuern des Motors in den vollständig erregten Zustand erhöht wird, so dass eine hohe Bremskraft mit einem guten Ansprechverhalten erhalten wird, wird verhindert, dass der Startstrom übermäßig wird, indem eine Hochfrequenzsteuerung nur beim Starten ausgeführt wird. Somit wird die Verringerung bei der Batteriespannung minimiert und somit wird das Auftreten einer Fehlfunktion in dem Steuersystem von unterschiedlichen elektrischen Komponenten, die im Fahrzeug verwendet werden, minimiert.

Method and device for automatically reducing the relative slip of a pair of axle shafts of a motor vehicle

A method and a device for implementing the method for automatically reducing the relative slip of a pair of axles of a motor vehicle are described. For this purpose, vehicles are equipped with lockable differential gears, which are locked as a function of a predetermined threshold value for the relative slip. In vehicles of this type the threshold value is set relatively high so that the differential gear is not locked simply due to the negotiation of very tight curves. With this method of operation, however, very great tyre wear has to be sustained owing to undetected slip of the wheels in relation to the ground. In order to achieve a more sensitive response of the differential gear lock, according to the invention the threshold value for the relative slip is adjustable as a function of the steering angle of one of the steered wheels. As a result it is possible to determine how great the actual wheel slip in relation to the ground is from the total measured relative slip of the axle shafts ...

ASR을 운영할시에, 운전자는 임의의 시간에서 제동을 할수 있으며 스티프(stiff)한 브레이크 페달과 마주치지 않는다. ABS는 두개의 보조 밸브 예를들면 변환 밸브와 로딩 밸브의 도움이 있는 ASR 경우에 압력 발생기로서 역활을 하는 흡기 복귀 펌프에 장착된다. 슬립성을 먼저 보여주는 선택된 축선상에 차륜의 브레이크 압력은 보조 밸브에 의해 조정되고, 반면에 모든 다른 차륜의 브레이크 압력은 ABS 밸브에 의해 조정된다. 이러한 방식에서 브레이크 압력은 적어도 한개의 차륜 브레이크에 항상 닿을 수 있다. 만일 ABS가 반응하면, ASR은 차단된다. When operating the ASR, the driver can brake at any time and does not encounter a stiff brake pedal. ABS is mounted on an intake return pump, which serves as a pressure generator in the case of ASR with the aid of two auxiliary valves, for example, a conversion valve and a loading valve. The brake pressure of the wheels on the selected axis, which shows the slip first, is adjusted by the auxiliary valves, while the brake pressures of all other wheels are adjusted by the ABS valves. In this way the brake pressure can always reach at least one wheel brake. If ABS reacts, ASR is blocked.
