Title: Shock resisting energy absorbing device
IPC: F16F7/00
Filed: 1974-05-14
Abstract: 1447005 Energy absorbing devices HARTWELL CORP 14 May 1974 [10 Aug 1973] 21317/74 Heading F28 In an energy absorbing device comprising a support member 1, 39 carrying an energy absorbing member 4, 40, and a carrier 6, 42 movable with respect to the support member and carrying balls 11 or rollers 47 for deforming the energy absorbing member, the balls or rollers are movable on a cam surface (cone 9, or surface 45) on the support member against the bias of a spring 15, 50, on shock loads, to increase the degree of identation of the energy absorbing member, and hence the energy absorbed. In the embodiment shown in Figs. 2 and 4 the spring 15 urges the balls 11 to the position of minimum indentation shown in Fig. 2. This position is maintained when the carrier 6 is moved to the left w.r.t. the support member 1, so that this stroke absorbs a minimum of energy. When the carrier 6 is moved instead to the right at a regular speed (Fig. 3 not shown), the spring 15 yields slightly, the balls 11 move further into the cone, indentation of the energy absorbing member 4 increases, and so more energy is absorbed. Should a shock load occur (Fig. 4) the balls effect maximum indentation of the member 4 which may cause the relative movement to cease. When the shock is over the spring 15 causes the balls to move outwardly of the cone. In the embodiment of Figs. 6-9 (not shown) the support member is a rectangular housing, the energy absorbing member is formed as strips lining the housing, the carrier is a shaft movable within the housing and having on its end a cam surface carrying rollers, the rollers being biased by a coil spring acting against a shoulder on the shaft. In the embodiment shown in Fig. 15, a spiral spring 50 acts between the carrier 42 and a disc 48 to cause stop segments 49 on the disc to urge the indenting rollers 47 to the position shown. Clockwise rotation of the carrier 42 produces little energy absorption because the roller 47 is at the left hand end of the cam surface 45. Anitclockwise rotation at a regular speed produces the indentation shown, and when a shock load occurs, the roller forces the stop segment 49 back against the spring 50 to ride up the cam surface and indent the energy absorbing lining 40 still further.

Patent GB-635543-A (GB)
Title: Vehicle brake
IPC: F16D65/22
Filed: 1945-08-27
Abstract: 635,543. Hydraulic brake systems; drum brakes. HOYT, R. C. Aug. 27, 1945, No. 21985. [Class 103 (i)] In a vehicle brake system, the brakes of one set of wheels are applied by the braking reaction on shoes of the brakes of another set of wheels, acting through hydraulic transmission means. The braking reaction on one shoe of a brake may be transmitted to the other shoe of the same brake by means of a hydraulic cylinder, the piston arrangement being such that the force transmitted to the other shoe is relatively reduced and this cylinder may serve to transmit the pressure to the other set of brakes. The two brake sets may be those of the front and rear wheels and the rear wheel brakes may apply the front wheel brakes or vice versa. As shown, the pressure chamber 68, Fig. 5, and a master cylinder 49 is connected by pipe 69 to the primary cylinders 19 of the brakes R of the rear wheels of a vehicle and secondary cylinders 29 between the shoes of these brakes are connected by pipes 84, 81, 82 to the primary cylinders 19 of the front wheel brakes F and by pipes 84a to the secondary cylinders 29 of these brakes. The pipe 81 is connected also by pipe 79 to a chamber 77 of the master cylinder which is normally connected by port 74 to the reservoir 53 but which is cut off therefrom when the piston is moved to apply pressure to the primary cylinders 19 of the rear brakes. The master cylinder 49 is provided with the usual chamber 55 connected by port 66 to the reservoir and from which liquid may pass to the pressure chamber 68 during retraction of the piston, through ports 56 in the piston and past the sealing cup 59. The shoes 17, Fig. 3, of each brake are connected to pistons 21, 37 of the cylinders 19, 29 by links 26, 38 pivoted to the shoes at 26a, 39 and of U-cross-section so that in the release position they contact along their length with the inner edges of the shoe flanges. The pistons 37 are slidable in annular pistons 31 which normally abut on stops 33. Release springs 43 are attached to the shoes at 39 and to the pistons 31. Thus when the master cylinder is operated with the drum rotating counter-clockwise the braking reaction on the left-hand shoe is transmitted by the adjacent pistons 37, 31, one of which engages the other, to the other piston 37 and the right-hand shoe of the same brake which anchors through the right-hand link 26 and piston 21 on the cylinder 19, the force thus transmitted to the right-hand shoe being reduced in accordance with the ratio of the area of piston 37 to the sum of the areas of pistons 37, 31. The pressure in the cylinders 29 of the rear brakes is also transmitted by pipes 84, 81, 82 to the cylinders of the front brakes which are thus also applied. By suitable proportioning of the piston diameters the pressure applied to the several brake shoes may be substantially equal. If the wheels are rotating clockwise, the right-hand shoes of the rear brakes become effective for applying the other shoes and brakes.

Abstract: 500,625. Friction clutches ; combined clutch and brake mechanism. SCHULER AKT.-GES., L. Aug. 11, 1937, No. 22133. Convention date, Aug. 11, 1936. [Class 80 (ii)] A clutch arranged on the shaft of n press comprises a split ring 5 encircling a pair of discs 8, 9 secured to the shaft within a driving drum 4 journalled on the shaft, one end of the ring 5 abutting against a projection 43 on the discs while the other end abuts against a lever 11 pivoted on the discs. A spindle 17 journalled in the discs has throe arms 18, 19, and 25, the first of which carries a roller 16 engaging the cam end 15 of the lover 11, the second carries a roller 20 co-operating with a cam surface 45 formed on a fixed drum 34, while the third is engaged by a spring-urged sleeve 24 slidable in a projecting part 21 of the disc 9. A spring-retracted brake shoe 35 pivoted on the disc 9 carries a roller 37 co-operating with a cam 39 on the spindle 17. A spring-rotracted lever 27, pivoted on a fixed pin 26, is normally held in the position shown in Fig. 3 by a pivoted catch 31. In this position. the shoe 35 is engaged with the fixed drum 34, as shown in Fig. 3, and the clutch ring 5 contracts away from the drum 4, as shown in Fig. 1. On releasing the catch 31, the sleeve 24 acts, through its spring and the arm 19, to disengage the brake shoe and lightly engage the clutch. The discs 8, 9 thus begin to turn, and, as the roller 20 mounts the cam surface 46, the spindle 17 is turned further to increase the clutching pressure until the arm 18 reaches, or passes slightly beyond, a dead-centre position so as to maintain the clutch engaged when the roller 20 passes off the surface 45. The lever 27 now returns to, and is latched in, its original position. Towards the end of the revolution, the roller 20 engages the cam surface of the lever 27 to disengage the clutch and apply the brake, the shaft 1 being stopped in a predetermined position by the roller 20 coming into engagement with the end 48 of the cam 45. According to the Specification as open to inspection under Sect. 91, the initial engagement of the clutch may be produced directly by hand, or by pressure fluid, or an auxiliary clutch may be used to cause engagement of the main clutch. This subject-matter does not appear in the Specification as accepted.
