Abstract:
PCT No. PCT/US94/03602 Sec. 371 Date May 2, 1995 Sec. 102(e) Date May 2, 1995 PCT Filed Apr. 1, 1994 PCT Pub. No. WO95/26895 PCT Pub. Date Oct. 12, 1995A nut and bolt assembler comprises a threaded bolt (78a) having a proximal end (140) with a knurled outer surface (142). A nut (144) is press fit onto the bolt knurled proximal end (190) to prevent rotation of the nut (144) with respect to the bolt (78a). Preferably, the knurled outer surface preferably comprises axial splines (142). The connection is most useful on the proximal end of a caging bolt (78a) in a spring brake actuator (10) having a hollow actuator rod (60) into which a head (86) at a distal end of the caging bolt (78a) is positioned with the proximal end (140) of the caging bolt (78a) extending out of the brake actuator through a threaded aperture (77) in an end portion of a brake actuator housing (52). A washer (148) can be provided between the nut (144) and the brake actuator housing (52) to prevent foreign material from entering the break actuator housing (52) through the threaded aperture (77).
