Title: Improved vehicle braking apparatus
IPC: B60T1/06
Filed: 1964-11-04
Abstract: 1,091,665. Vehicle brake arrangements. RAYMOND CORPORATION. Nov. 4, 1964 [Oct. 16, 1964], No. 45062/64. Heading B7H. [Also in Division F2] A disc brake arrangement (see Division F2) for use on an industrial truck, e.g. as disclosed in Specification 1,087,354, comprises a disc 40 arranged on the shaft 22 of a motor 20 which drives a steerable wheel via gears 33, 34, the motor and gearing being mounted in a frame 30 mounted on a turntable structure, a pair of pads 51, 60 engageable with opposite faces of the disc, and a floating caliper structure comprises two independent piston-and-cylinder actuators, one of which is arranged to apply both pads on admission of hydraulic fluid from a pedal-operated master cylinder, and the other of which is arranged to be pressurized by another master cylinder whenever the driver is seated in his cab to compress a spring assembly, normally tending to apply the pads when the driver's seat is unoccupied, whereby the latter arrangement acts as a parking brake and provides the equivalent of a dead man's handle. The pedal-operated master cylinder 32 pressurizes a chamber 88 in a block 48 which is axially movable, together with another block 46, by being mounted on slide shafts 50, 51 slidable in apertures in the frame 30. A result piston 44 acts on a plate 59, also carried by the slide shafts, to which are secured pads 60, so that the pads 60 are applied to the disc and the reaction moves the block 46 so as to apply another pair of pads 57, carried by a stepped piston 43 working in a bore in the block 46, to the opposite face of the disc. The piston 43 normally occupies an inner position in the cylinder bore owing to hydraulic pressure supplied by a master cylinder 31 to the annular chamber formed by the step of piston 43 comprising a pair of springs 54, 56, the hydraulic pressure being generated as a result of the weight of the driver acting via seat 18 on a lever 35. When the driver leaves his seat, or presses so hard on the pedal 23 as to lift himself off the seat, this hydraulic pressure is removed so that the springs 54, 56 apply the pads 57 directly and the pads 60 by reaction via the slide shafts 50, 51, or in the latter case augment the application force on the pads. Springs 70, 71, 76, 77 on the slide shafts act to centralize the floating structure to give pad clearance in the release position, the clearance on one side being adjustable by nuts 79, 80 which together with shims 80, 81 form adjustable anchorages for the springs 70, 71 against the frame 30. Springs 76, 77 may also be adjustable in this way, but as shown removable shims 41 fulfil this purpose.
