Problems solved by technology

This compression produces relatively high load forces on the outer inner guide wheel (and often the inner outer guide wheel), which undesirably lead to premature wear of the guide wheel

Embodiment Construction

[0020] Referring to the accompanying drawings, especially figure 1 , shows a non-limiting example of a monorail assembly 10 traveling on a monorail track 16 . The monorail assembly 10 includes a monorail 12 and two single axle bogies 14 operable to support the monorail 12 on a monorail track 16 . As described in more detail below, each of the single axle bogies 14 according to the present invention includes a traction control assembly 40 having a steering assist device 42 . The traction control assembly 40 provides structures that can help manage longitudinal traction forces, and the power steering device 42 helps manage the forces exerted on the guide wheels by adding shear forces on the monorail bogie 14 to counteract the shear forces exerted on the bogie by the secondary suspension system. 32 load force. As explained in more detail below, the steering assist device 42 thus helps to reduce and more evenly distribute the load forces applied to the guide wheels 32 during the...

Abstract

A traction control assembly for connection between a monorail bogie frame and a monorail car. The traction control assembly comprising a first traction link pivotally connected to a first bell crank mechanism and a second traction link pivotally connected to a second bell crank mechanism. The first traction link and the second traction link are capable of absorbing traction forces applied to the monorail bogie. The traction control assembly further comprises a cross link interconnecting the first bell crank mechanism and the second bell crank mechanism and a passive steering assist device interconnecting the first bell crank mechanism and the second bell crank mechanism.; The steering assist device causes the traction control assembly to insert shear forces on the monorail bogie during travel of the monorail bogie over a curved section of monorail track for facilitating rotational motion between the monorail bogie and the monorail car.

Description

technical field [0001] The present invention relates to the field of monorail bogies for supporting monorail vehicles and, more particularly, to monorail bogies including steering assist devices for enabling the steering wheel to be applied to the monorail guide wheels when on a curve of the monorail track. The load on the load is more evenly distributed. Background technique [0002] Monorail bogies for supporting monorail cars are known in the art and are used in many monorail car assemblies for supporting the running and guide wheels beneath the monorail car. [0003] Many monorail bogies support load wheels that run on the upper surface of the monorail track and guide wheels that run along the sides of the monorail track and provide lateral support for the monorail cars. A common problem with many such monorail bogies is that the load on certain guide wheels of the monorail bogie can increase significantly as the monorail bogie travels over curved sections of the track....
