A pair of axles A, B, are interconnected with each other and with the frame 2 of a mobile crane by means of torsion springs 1 each of which is formed from a series of leaf springs 3. The spring 1 on the off side of the vehicle is connected rigidly to the leading axle A; and by means of a pivotal connection with the trailing axle B. The axle on the near side of the vehicle is connected by a pivotal connection to the leading axle A, and is rigid with the trailing axle B. The middle portion of each spring 1 is held between plates 9 which have a pivot connection 20 with a respective U-shaped bracket 10 rigid with the frame 2. The extremities of the U-shaped bracket 10 may be drawn together by bolts 15. In operation, the springs 1 permit the axles A, B, to twist relatively to each other, as shown. Vertical deflection of the springs 1, due to bending in a vertical plane, is not possible.

In the system shown (which relates to Fig. 2 of Specification 1,350,525), a cavity 41 in the transmission casing 28 forms an annular reservoir of liquid metal when the casing is rotated, and a tube 40 fixed in the core 16 of the generator is thereby caused to convey the liquid into an annular groove 42 within the core 16 owing to the greater speed of core 16 relative to casing 28 (as detailed in the above Specification). A further tube 43 then conveys the liquid into an annular cavity 44 from where it passes via ducts 45 and 46, 47 to the contacts formed by slip rings 5, 35 and 6, 36. Excess liquid is able to pass back to the reservoir 41 via radial ducts 48, 49 in the cores 16, 17 of the generator, motor respectively.
