Title: Adaptive braking modulator
IPC: B60T8/46
Filed: 1975-04-09
Abstract: 1473278 Antiskid braking systems BENDIX CORP 9 April 1975 [22 April 1974] 14658/75 Heading F2F A modulator for an antiskid braking system comprises a housing 12 defining a chamber 42 having an inlet port 38, an outlet port 40 and an exhaust port, the chamber being divided into inlet and outlet sections 44, 46 connected to the inlet and outlet ports respectively an electrically operated valve 48 being normally in a first position connecting the inlet and outlet sections 44, 46 but preventing communication with the exhaust port and being shiftable when actuated into a second position preventing communication between the sections 44, 46 and connecting the outlet section to the exhaust port, there being also provided means responsive to actuation of the valve 48 and to the fluid pressure level at the inlet port 38 for restricting communication into the inlet section 44 when the valve is initially actuated and maintaining said restriction until the fluid pressure level at the inlet port drops below a predetermined level. A control member including a differential piston 66 slidably mounted in a chamber 64 and operating a valve member 84 is movable from a position allowing uninhibited fluid communication between the inlet port 38 and the chamber 42 to a position interposing a flow restricting orifice 90 therebetween upon actuation of the valve. A quick release valve 96 includes an atmospheric port 98 and diaphragm 100 which is forced into sealing engagement with housing 12 when inlet port pressure is greater than that in the housing, the edges of the diaphragm deflecting to permit communication with a flow path 78 connecting port 38 and chamber 42. When pressure at the inlet port is reduced below that in housing 12 diaphragm 100 is forced away to allow quick release of pressure to atmosphere. The modulator is combined with a conventional relay valve having a housing 14 and piston 16. When a brake application is effected high pressure fluid is fed to inlet port 38 and hence into primary chamber 18 of the relay valve through path 78, inlet section 44 and outlet chamber 46. A skid signal causes valve 48 to operate so that chamber 18 is connected to atmosphere to operate the relay valve to release the brakes. Compartment 68 of chamber 64 is also communicated to atmosphere causing valve member 84 to be moved into sealing engagement with seat 80 to restrict fluid flow from path 78 to section 44 so that unless the brake pressure delay cycle is such that brake pressure reaches zero each time as in a severe skid the pressure level in section 44 increases to a value less than line pressure so that braking pressure is modulated as shown in Fig. 2.
