Abstract

1351138 Railway vehicle undercarriages DUNLOP HOLDINGS Ltd 19 April 1971 [7 April 1970] 16284/70 Heading B7L [Also in Division F2] The axle box 7 of a rail vehicle is supported from the underframe 9 by two shear/compression springs 1, 2. Each spring comprises a stack of V-shaped section resilient blocks 3, parallel V- shaped section metal plates 4 interleaved between and bonded to the blocks, and end plates 5, 6. The width of the base of the V decreases from the apex end of the stack (i.e. that attached to the axle box) to the other, and a cavity 10 extends through the apex end plate 5 into at least the first block 3. The plates and blocks decrease in length (the dimension perpendicular to the plane shown) towards the apex end of the stack. Successive blocks are displaced in the direction perpendicular to the plane shown so that the stack has an echelon profile. The end plate 6 of each spring is attached to the vehicle underframe 9 by an adaptor block 11 which engages a vertically extending cut-out 12 formed in the underframe. The cut-out provides transverse location of the spring. Vertical location is achieved by the adaptor block 11 abutting the underside of the underframe 9. The end plate 5 of each spring is provided with studs 13 to engage sockets 14 formed in the axle box 7. Provided the end plate 5 is biased towards the axle box by its spring, the studs and sockets prevent vertical movement between the end plate and the axle box. Alternatively the studs 13 may be provided with split pins or other similar releasable means to hold the spring in engagement with the axle box 7. The end plates may instead be permanently secured to the axle box.
