Abstract

1,084,727. Railway vehicle undercarriages. ABEX CORPORATION. Nov. 17, 1964 [Dec. 12, 1963], No. 46836/64. Heading B72. [Also in Division F2] In a braking unit adapted to be secured to the bogie of a railway vehicle, a pair of brake beams 35, 40 are disposed on opposite sides of a bolster 15 which is mounted on springs 16 for vertical movement relative to the side frames 13, 14 of the bogie and brake beam operating means includes a beam operating lever 28 extending upwardly from one of the brake beams 40 at an angle to the vertical to be in operative connection with a horizontally mounted force multiplying lever means 26 operated by the piston means of a brake actuating cylinder 20. The brake actuating cylinder 20 and the force multiplying lever 26 are mounted on the bolster 15 for vertical movement with the latter such that the intersecting contact point 55 between the beam operating lever 28 and the force multiplying lever 26 is varied with movement of the bolster such that any change in the loading of the railway vehicle changes the multiplying effect of the force multiplying lever 26 so that the amount of braking force applied to the force multiplying lever 26 to the brake beam operating lever 28 increases as the weight of the railway vehicle increases, and decreases as the weight of the railway vehicle decreases. The brake beam operating lever 28 acts as a live lever and is interconnected by means of a horizontal rod 30 with a dead lever 32 the upper end of which abuts against a lug 44 formed on a slack adjuster 45 associated with the brake actuating cylinder 20. The position of the lug 44 on the slack adjuster 45 may be adjusted manually by rotation of an exterior handle 80 attached to a threaded shaft 82 or alternatively, the adjuster lug 44 may be automatically adjusted when the stroke of the brake actuating piston exceeds a predetermined amount. Provision is made for the attachment of a hand brake pull rod 150 to the pin 50 associated with the end 25 of the piston-rod 22, so that the pull rod 150 actuates the force multiplying level 26.
