A rocker arrangement comprises a rocker member 32 and an adaptor member 28, the rocker member 32 and the adaptor member 28 having co-operating surfaces arranged to allow the rocker member 32 to tilt relative to the adaptor member 28, and a resiliently deformable component 3 8 arranged to apply a restoring force in the event of tilting of the rocker member 32 relative to the adaptor member 28.
摘要:
A truck arrangement comprising a wheelset 38 carrying a saddle member 35, a resiliently deformable rocker member 42, 44 being interposed between the saddle member 35 and the wheelset 38, the rocker member 42, 44 being resiliently deformable to damp lateral accelerations of the wheelset 38 relative to the saddle member 35.
摘要:
A railway truck frame (20) for a railway truck including a first side frame (50) and a second side frame, each side frame having an inverted trapezoidal-shaped window (68) including a first inclined side and a second inclined side. The truck frame also includes a bolster (54) having a first end and a second end which extends transversely between the first and second side frames. Each end of the bolster includes a first inclined channel and an opposing second inclined channel. Each channel includes an exterior flange, a spaced apart interior flange, and a bearing surface located between the exterior and the interior flanges. Each inclined side of a window is adapted to be located in a respective first or second channel between the exterior flange and the interior flange ofthe channel and in engagement with the bearing surface of the channel. A locking device (180) such as a jack is located in each window between the top of the end of the bolster and the top side (78) of the window which selectively forces the end of the bolster downwardly into engagement with the side frame such that the end ofthe bolster is rigidly but removably connected to the side frame.
摘要:
A friction damping arrangement for a railway vehicle comprises first and second relatively moveable vehicle components (14,16), a friction wedge (18) having a surface (37) arranged to co-operate with a surface of the second vehicle component (16), and resiliently urged towards the first vehicle component (14), and a resiliently deformable component (48), located between the first vehicle component (14) and the friction wedge (18), the resiliently deformable component (48) being deformable to allow relative movement between the first vehicle component (14) and the friction wedge (18).
摘要:
A side bearer comprises a lower component 10, an upper component 20 guided for generally vertical movement relative to the lower component 10, and resilient biassing means 18 urging the upper component 20 away from the lower component 10, the resilient biassing means 18 further being arranged to resist horizontal or longitudinal relative movement between the upper and lower components 10, 20 by shearing thereof.
