PURPOSE:To increase the height of get-over, to keep an initial axle weight share ratio from fluctuating and to reduce the weight transfer from an axle, by lengthening an equalizer, optimizing the angle of a shackle and lowering the mounted position of a torque rod at the side of the axle. CONSTITUTION:An equalizer 7 is set at a lever ratio divided in inverse proportion to an initial axle weight share ratio required for axles 5, 6. The ratio between the constants of springs 9, 10 is made equal to the initial axle weight share ratio. As a result, the initial rest angle of the equalizer 7 is prevented from fluctuating due to carried weight. The total length of the equalizer 7 is made large within such a range that the asymmetric ratio of the springs 9, 10 is not greatly changed. The span of the springs 9, 10 is lengthened. The angle of shackles 8 as to the vertical line is set at 0 to 10 deg.. The mounted positions of torque rod 15, 16 at the sides of the axles 5, 6 are made lower than the straight lines extending on the center lines of the axles 5, 6 and the centers of mounting of the rods 15, 16 opposite the axles 5, 6. Wearresistant silencing pads 17 are interposed between the contact portions of the springs 9, 10 and front and rear hangers 2, 4. |
