Non-driving bearing axle device for trailer
2008
The utility model relates to the technical field of non-driving axles of vehicles, and in particular relates to a non-driving bearing axle device for a trailer. Aiming at overcoming the disadvantage that the deformation of the leaf spring in the prior art fails to adapt to unsmooth roads, the utility model provides a non-driving bearing axle device for a trailer, which comprises an intermediate axle assembly, a leaf spring mounting rack assembly, a leaf spring assembly and a wheel assembly, and further comprises a rocker assembly arranged between the intermediate axle assembly and the wheel assembly. The rocker assembly can rotate around the intermediate axle assembly within certain angle range; the leaf spring assembly is arranged in the middle of the rocker assembly and is connected with the end of the intermediate axle assembly; and the leaf spring assembly is fixed on the leaf spring mounting rack assembly through a leaf spring keep plate. The non-driving bearing axle device can adapt to unsmooth roads through the deformation of the leaf spring and can adapt to the height changes through the swinging of the rocker, thus improving the capability of adapting to unsmooth roads and the off-road performance the trailer.
