    摘要： Selectively engagable auxiliary leaf springs (38 or 138) for vertically supporting a vehicle chassis (32) on an axle assembly (22 or 102) in parallel with main suspension springs (34 or 114). In three of the disclosed embodiments, both ends (38b,38a) of the auxiliary springs (38) are pivotally atached. In two other embodiments, one end (138a) of the auxiliary leaf springs (142) is pivotally attached and the other end (138b) is rigidly affixed in cantilever fashion. Actuators (56 or 142) are employed to selectively enable or increase load supporting of the auxiliary leaf springs. One of the actuators is a hydraulic actuator (142) which receives pressurized fluid from a pump (148) driven by jounce of the axle assembly (22 or 102).

    摘要： A vehicle suspension arrangement for a vehicle having a chassis rail and a transverse axle arranged substantially orthogonal to the chassis rail is provided. The vehicle suspension arrangement includes a coil spring having a predetermined resilience characteristic, a first end for coupling to the chassis rail of the vehicle at a primary coupling, and a second end disposed axially distal from the first end for coupling to the transverse axle. The vehicle suspension arrangement also includes a secondary leaf spring having a plan view longitudinal configuration, a first end for pivotally coupling to the chassis rail of the vehicle at a secondary pivot coupling, and a second end for coupling to the transverse axle. The entire length of the plan view longitudinal configuration of said secondary leaf spring extends in a single substantially linear direction that is arranged to be angularly displaced with respect to the chassis rail.

In three of the disclosed embodiments, both ends (38b,38a) of the auxiliary leaf springs (38) are pivotally attached. In two other embodiments, one end (142a) of each auxiliary leaf spring (142) is pivotally attached and the other end (142b) is rigidly affixed in cantilever fashion. A manually operated hand crank (60) or ratchet mechanism (87) employed to drive a speed reducer actuator (62) to selectively enable or increase load supporting of the auxiliary leaf springs.
