Problems solved by technology

However, most of these attempts were unsuccessful
Existing successful mechanically and autonomously driven steerable wheel assemblies can only pivot the trailer at a fixed, predetermined point along the length of the trailer, which limits trailer flexibility

Embodiment Construction

[0032] The drawing shows an independently supported and independently steerable unitary wheel assembly 10 which is self-contained and adapted to be mounted on a trailer body 11 . Figure 4 and Figure 5 In particular, it shows the wheel parts fixedly mounted on the linear bearing actuator 30 on the underside of the trailer body 11 .

[0033] figure 1 Shown is a trailer body 11 with five individual wheel members evenly spaced along the entire length of the trailer body. Due to the independent nature of the wheel components, each tire has its own independent suspension system and handles independently of all other tires, and thus can be evenly distributed along the length of the trailer.

[0034] Smooth turning of a trailer with non-towed tires is achieved by using the wheels at the front end of the trailer that turn at a greater angle than the wheels at the rear end, with the tires in between them turning at an incrementally smaller angle. Different turning angles depending ...

Abstract

A single wheel unit adapted to be mounted on a vehicle body ( 11 ) comprising: a wheel frame supporting a suspension mechanism ( 15 ) and a wheel assembly mounted on the suspension mechanism ( 15 ), and steering means mounted between the wheel frame and vehicle body ( 11 ) for pivoting the wheel frame relative to the vehicle body ( 11 ) so as to steer a vehicle, wherein the steering means includes two steering components ( 30 ) pivotally attached ( 32, 33 ) one at each of the leading and trailing portions of the wheel frame and capable of being actuated to independently displace the leading and trailing portions laterally of the vehicle body ( 11 ).

Description

technical field [0001] The present invention relates to a steerable single wheel unit, particularly for a heavy transport trailer having a single wheel set. Background technique [0002] About 20% of heavy-duty transport trailers are extremely heavy-duty trailers used to transport larger loads. These trailers require a dual wheel system with front and rear trailer axles with adjacent pairs of dual wheels to support excessive loads. The remaining 80% of heavy duty trailers are capable of supporting the maximum payload with one wheel set. [0003] The wheels on most trailers are mounted on cross axles which are grouped at the front and rear of the trailer to facilitate maneuvering the trailer and reduce tire buckling. However, the flexibility of such trailers is limited. Putting tires on the middle length of a trailer is not appropriate because the tires drag on the road every time the trailer makes a turn, causing a lot of wear on the tires and wear on the road. Also, tir...
