Abstract

The chassis e.g. for a personal carrier comprises a first frame member (10), having a first pair of coaxial wheels (14), a second frame member (12) having a second pair of coaxial wheels and means pivotally connecting the first to the second frame member on a pivot axis (20) which lies in the direction of vehicle travel. This arrangement allows large vertical deviations in the track to be followed. The wheels may be located in suspension arrangements in the frames (10, 12) to follow small deviations. The vehicle may be powered by a D.C. traction motor 28 and may have two roofed passenger compartments 32, a central housing for battery 34 and equipment storage space 36. <IMAGE>

Description

SPECIFICATION Rail vehicle This invention relates to a rail vehicle and more particularly to the wheeled chassis on which the vehicle body is located.
A chassis for a rail vehicle according to the invention includes a first frame member, a first pair of wheels which are attached for rotation on a common axis to the first frame member, a second frame member, means pivotally connecting the first to the second frame member on a pivot axis which lies in the direction of vehicle travel and a second pair of wheels on the second frame member.
The first pair of wheels may be attached to a common axle.
In one form of the invention the first frame member is in plan substantially H-shaped with the first pair of wheels located between two legs of the H and the second frame member and second pair of wheels located between the remaining pair of legs of the H. Preferably the first frame member includes means at or near the free ends of the legs of the H for attaching the vehicle body to the frame member. Conveniently, the wheels are connected to the frame members through suspension arrangements.
A rail vehicle according to the invention includes a chassis as described in any of the above statements. The vehicle preferably includes a motor and means connecting the motor to the first pair of wheels to drive the wheels.
The invention is now described by way of example with reference to the drawings in which: Figure 1 is a side view of the vehicle of the invention, Figure 2 is a sectioned side elevation of a rail vehicle chassis seen on the line 2-2 in Fig. 3, and Figure 3 is a plan view of the chassis of Fig. 2.
The rail vehicle chassis of the invention is shown in Figs 2 and 3 to include a frame member 10, a sub frame member 1 2 and rail wheels 14.
The frame member 10 is, as seen in Fig. 3, substantially H-shaped in plan. One pair of wheels 14 are fixed to a live axle 1 6 the ends of which are journalled for rotation in suspension assemblies in the legs 1 8 of the frame.
The frame 1 2 is U-shaped and connected to a cross-member of the frame 10 by a pivot pin 20 which locates the frame 1 2 between the remaining legs 22 of the frame 10. The arms of the frame 1 2 carry the remaining wheels 1 4 with the stub axles of the wheels located in suspension arrangements in the frame arms.
The free ends of the legs 1 8 and 22 r+ the frame 10 each carry a rubber or like shock mounting arrangement 24 to which the body 26 of a rail vehicle is attached.
A D.C traction motor 28 is attached, as seen in Fig. 3, to the frame 10 and connected through a suitable gear drive 30 to the axle 16.
Fig. 1 illustrates a personal carrier body 26 which is located on the chassis of Figs 2 and 3. The body 26 includes two roofed passenger compartments 32, a central housing for a battery 34 for the motor 28 and a stretcher or equipment storage space 36 between two passenger compartments 32.
The body is shock mounted on the mounting arrangements 24 on the frame 10.
Slight vertical deviations in the track on which the vehicle is to operate are accommodated by the wheel suspension arrangements.
Larger deviations, such as those that occur on underground mine tracks are followed by the wheels on the frame 1 2.
