Abstract
1,186,322. Fluid pressure brakes. WESTINGHOUSE BREMSEN UND APPARATEBAU G.m.b.H. 11 Sept., 1968 [11 Sept., 1967], No. 43189/68. Heading F2F. In a variable-load brake controls means 1-16 of a generally-known construction, the mechanical advantage of a lever system 17-22 is varied according to vehicle loading by movement of a fulcrum between two adjustable limits. Levers 18, 21 pivot about a fulcrum 20 ,which is urged by a first force due to a pistonrod 31 of an adjusting piston 32, the chamber 33 of which communicates via union 34 with a medium (e.g. compressed air) of which the pressure depends upon the load, fulcrum motion being opposed by a second force due to a compression spring 46 disposed between a fulcrummounting member 29 and a spring plate 45. A guide-collar 30 of the member 29 projects into a first socket 35 screwed into a housing 1, which socket has a stop 36 for a stop surface 37 of the collar. Screwed into the first socket is a second 38 of which the inner end surface forms a stop 39 for a stop surface 40 on the collar. The positions of the sockets are secured by respective lock nuts 41, 42. Prestressing of the spring 46 is effected by adjustment of a screw 44 in the cover 43 of socket 38 after removal of a dust cover 46. Under a minimum load condition the fulcrum moves to the left until stop surface 37 contacts stop 36 at which point maximum reduction of the controlled brake pressure is achieved and vice versa.
