A steerable wheel assembly for a vehicle comprises a mounting bracket 1 incorporating a vertical pivot mounting 2 for attachment to the vehicle. A second bracket 6 has a first arm 7 carrying a road wheel and a second arm 8 generally upstanding from the first and linked at the upper end thereof to the mounting bracket 1 by a parallelogram linkage 4, 5. A spring and shock-absorber unit 9 is pivotally connected between the second bracket and the parallelogram linkage 4, 5. Another aspect of the invention provides a vehicle suspension system comprising a mounting bracket 20 for attachment to a vehicle body or chassis, and a wheel-mounting arm 21 pivotally attached to the mounting bracket and having a wheel mounted thereon. A spring and shock-absorber unit 22 ex tends between the mounting bracket and the wheel-mounting arm, at least one end of the spring and shock-absorber unit being connected through a member 23 whose position is adjustable along the axis of the respective bracket or arm. |
