Abstract: A hydraulic/mechanical braking system for a vehicle comprises a cam (128) keyed onto a transmission shaft or a trailing wheel and at least two hydraulic cylinder assemblies (126,129) including a cam follower (127). A hydraulic circuit (C) connects the hydraulic cylinder assemblies together. A master brake valve (113) controls the flow of fluid in the circuit. Actuation of the master brake valve (113) obstructs the flow of fluid and hence the reciprocation of the hydraulic cylinder assemblies, forcing the cam following against the cam to resist rotation. The system further comprises an energy recovery system configured to transfer energy from the hydraulic fluid flowing in the hydraulic circuit to generate electricity and/or to recover heat from the hydraulic fluid flowing in the hydraulic circuit.

The cam (128) is formed with two opposing flat faces (142, 143) in order to provide an anti-lock braking system (ABS).

Abstract: A known vehicle front wheel suspension incorporates a cross-member of sheet material adapted to support a wheel suspension assembly at each end of the cross member. Each assembly comprises a lever arm shock absorber mounted on an upper location on an end of the cross-member having a damped lever arm serving as an upper arm for the wheel suspension; the inner end of the damped lever arm being adapted to rotate about a first axis of fixed alignment relative to the cross member; a lower arm pivotably attached at its inner end to a lower location on an end of the cross-member so as to rotate about a second axis of fixed alignment relative to the cross member; a wheel carrier pivotably located by and between- the outer end of the upper arm for rotation about a third axis, and the outer end of the lower arm for rotation about a fourth axis; the first, second, third and fourth axis all being parallel to one another; and a coil spring acting between the lower arm and the cross member.
