Title: Flow control valve for a braking system
IPC: B60T15/60
Filed: 1972-10-16
Abstract: 1411981 Tractor/trailer braking systems EATON CORP 16 Dot 1972 [26 Oct 1971] 47595/72 Heading F2F A relay valve 26 for use in a tractor/trailer braking system controls the application of the trailer brakes 24 in the event of pressure in an emergency line 38 falling below a predetermined level. During start-up of the vehicle a compressor driven reservoir supplies compressed air, to an inlet 38 of valve 26 by way of line 38, air then flowing past a check valve 102, passages 94, 72 respectively formed in a check valve assembly 88 and spool 70, passages 69 in a bobbin 64 and port 52 to charge a reservoir 28. As pressure builds up check valve assembly 88 moves rightwardly causing a nose portion 86 to firstly seat against seal 76 thereby closing communication between port 52 and a port 56 leading to an application line 42 and thereafter to unseat seal 76 from a shoulder 80 to establish communication between a port 50 and port 56. To initiate a braking application a treadle valve 16 is operated thereby passing air from reservoir 14 to port 50, and hence port 56 by way of a service line 40. The pressure in application line 44 then operates a valve 30 and air is allowed to pass from reservoir 28 to actuate brakes 24 by way of ports 52, 54, a supply line 44 and valve 30. If emergency line pressure is lost, for example by disconnection of the emergency line after the trailer is parked, a spring 106 shifts check valve assembly 88 leftwardly and spool 70 also moves leftwardly to isolate port 50 from port 56. Thereafter nose portion 86 moves away from seal 76 thereby establishing communication between ports 52, 56 and allowing the reservoir pressure to actuate valve 30 so that the brakes may be actuated through pressure in line 44. Valve 30 is solenoid operated under the control of an antiskid circuit 31 to relieve the braking pressure under skid conditions. In the construction shown in Fig. 3 comprising the subject matter claimed in which the brakes include a spring applied, air pressure released portion emergency actuator valve 26 is fitted with a cartridge 110, having a further check valve assembly 118 which during normal braking permits passage of air to the pressure hold-off chamber 140 of the brake. If the emergency line 38 pressure fails this assembly (118) shifts leftwardly causing a check valve plate 124 therein to engage a projection 132 whereby the pressure in the hold-off chamber is released gradually to cause the brake to be spring applied at the same time as the normal apply pressure in apply chamber 142 of the brake decreases. The claims are directed to the Fig. 3 embodiment of valve 26.

Title: Controlling braking forces on the wheels of trailers
IPC: B60T7/20
Filed: 1975-11-26
Abstract: 1497179 Trailer overrun brakes; automatic control DAIMLER-BENZ AG 26 Nov 1975 [20 Dec 1974] 48644/75 Headings F2F and F2E To control the braking forces on the wheels of a trailer for eliminating forces occurring in the coupling 2, (3) between a towing vehicle and the trailer (i.e. for eliminating overrun), a static force reference value and at least one dynamic force value of the forces occurring in the coupling 3 are measured electrically and combined to form an electrical control signal which regulates the trailer breaking forces. As particularly described, the static force reference value is the "overrun path" of the trailer, that is the distance by which the connection from the trailer axle to the trailer coupling varies when the trailer runs into the towing vehicle, a first said dynamic force value is overrun speed and a second (optional) said dynamic force value is overrun acceleration. In the illustrated embodiment a potentiometer 6 mechanically connected to a towbar 2 provides a signal proportional to the overrun path which signal is fed via a changeover switch 25 to a matching amplifier 26 at the output of which an electrical signal proportional to the overrun path appears, and to a differentiating element 28 at the output of which an electrical signal proportional to overrun speed appears, which signal passes to another differentiating element 30 at whose output appears an electrical signal proportional to overrun acceleration. The three signals are applied to a summing amplifier 32 via respective multiplier elements 27, 29, 31, and thence to a comparator 33 and via a power amplifier 35 and a diode 40 to an electric trailer brake 38. The power amplifier 35 is connected to a current source only when a switch 36 is closed by operation of a brake pedal B. When reverse gear is engaged or the reversing lamp is switched on the switch 25 is switched over, the input magnitudes are reversed in polarity and may be differently weighted, and the voltage from potentiometer 6 now passes by way of an inverter amplifier 41. A voltage source 13 is provided on the trailer which acts on the trailer brake 38 if the trailer breaks away to close a switch 39.
