Synthesis and analysis of the steering system of an adjustable tread-width four-wheel tractor

Dynamic effect of the bump steer in a wheeled tractor

“…The first variant is an existing model, exhibiting a larger bump-steer. The second variant has the geometry of the steering system improved, by minimizing the kinematic crosscoupling between the steering control and the axle oscillation following the approach described in [1].…”

“…The purpose of this undertaking was to validate the kinematic analysis results generated with an in-house computer program used previously [1,5], and to evaluate the dynamic effects of the cross-coupling between steering and axle oscillation, and of the occasional impacts that can occur between the axle-beam and the bump-stops mounted on the tractor body.…”

“…Reports on the Ackermann linkage analysis and design are available in a number of publications (see [1] and the references therein). This is a symmetric spatial four-bar function generator, which ensures that the steered wheels pivot at a certain ratio imposed by the condition of correct turning, viz.…”

“…The steering-control linkage has been also investigated by researchers, and some design recommendations can be found in the literature [1][2][3][4][5]. The configuration schematized in Fig.…”

Assessment of a Boat Fractured Steering Wheel

“…Previous research on steering wheels mainly concentrate on mechanisms of force transmission [19], impact in case of collision [20] and ergonomics [21]. Nevertheless, no previous work had been found that deals with crack occurrence or fracture of steering wheels of any kind.…”
