A steering assembly for a lawn maintenance vehicle having a control assembly that receives a user rotational input, a transfer assembly for transferring the rotational input from the user to a pair of wheel assemblies. Each wheel assembly includes a knuckle connected to a pivot bar by way of a kingpin, wherein the kingpin is positioned within the rim of the tire operatively connected to the knuckle. The transfer assembly includes a sector gear having a leading edge that forms a rack that is meshingly engaged to a pinion gear of the transfer assembly.

A crane for lifting and transporting loads includes a base frame, for transferring the loads of the crane onto a support surface by a plurality of wheels having two steering wheels; and a steering system. The steering system includes a linear steering actuator, which is hinged, on one side, to the base frame and, on the other side, to a bar having two ends. Each end of the bar is hinged to a respective rotary element around a respective hinging axis. Each rotary element rotates around a respective rotation axis and is constrained in rotation to the respective steering wheel to steer it.

Methods and systems are provided for a steering system for a vehicle. In one example, the steering system may include a steering assembly with a first linkage assembly extending along a first direction between a vehicle steering wheel and a first wheel plate of the steering assembly. The steering system may also include a second linkage assembly with a sliding middle link extending along a second direction between the first wheel plate and a second wheel plate of the steering assembly.

The present invention is a steering system for a beam-type solid axle arrangement. The steering system is designed to operate in conjunction with the triangulated link-style suspension system with zero bumpsteer during suspension travel and negligible bumpsteer during articulation. Accurate steering throughout suspension operations is satisfied with mechanical linkages that include a slow ratio rack and pinion gearset and unique augmented chain and sprocket assembly. The slow ratio of the rack and pinion gearset ensures negligible bumpsteer during articulation, thereby leading to negligible if any bumpsteer throughout operation of the suspension system. Meanwhile, augmentation of the chain and sprocket assembly defines a steering quickener effect thereby speeding up the rack and pinion gearset and restoring quick steering response. Effortless steering is ensured by appropriate use of electric or hydraulic assist devices.

A wheel suspension includes an axle limb which supports a wheel. The axle limb includes a first steering axle which provides a first steering angle in a specified range for the wheel, and components for connecting the axle limb to a support structure. At least one of the components includes a second steering axle which is selectively releasable in order to provide a steering angle which is different than the first steering axle. The components for connecting the axle limb to the support structure form a McPherson suspension.

An air reservoir for a steering axle is mounted on a trailer, the steering axle comprising a pair of rotation pivoting wheel assemblies. Each wheel assembly has a rotation plate and a steering arm connected thereto. A rod pivotally connects the steering arms, each wheel assembly being rotatably connected to either end of the axle. An air stabilizer assembly is mounted on the axle and is connected to the rod, the air stabilizer assembly having an inflatable damper assembly thereon. An air supply is fluidly connected to an air inlet on the axle, the air inlet being fluidly connected to the damper assembly. The air stabilizer assembly dampens pivotal movement of the wheel assemblies when compressed air from the air reservoir fills the damper assembly. The air stabilizer assembly allows the wheel assemblies to rotate more freely when pressure of the compressed air within the damper assembly is reduced.
