Abstract

The bogie includes a housing (12) which carries a wheelset of four wheels (14), the housing being attached to the vehicle body by means (38) which enables the housing to rotate on a vertical axis relatively to the body. A motor (10) is located on the rotational axis of the housing and means (16, 18 and 20) in the housing (12) connect the motor to at least one wheel of the wheelset. <IMAGE>

Description

SPECIFICATION Vehicle bogie This invention relates to a self propelled or driven vehicle bogie.
A vehicle bogie according to the invention includes a housing which carries a wheelset, means for connecting the housing for rotational motion on a vertical axis to a vehicle body, a prime mover and power transmission means connecting at least one wheel of the wheelset to the prime mover.
Further according to the invention at least a portion of the transmission means is located in the housing and the prime mover is a motor which is located above the vehicle body connecting means with the rotor shaft of the motor being vertically located in the housing on its axis of rotation and engaged with the transmission means.
Preferably the wheelset includes two pairs of wheels with at least one wheel of each pair being connected to the rotor shaft of the motor through the transmission means. In a preferred form of the invention each wheel of the wheelset is independently connected through the transmission means to the rotor shaft of the motor.
In one form of the invention the wheels of the wheelset are each connected to the housing on swing arms.
The transmission means may include a gear train in the housing between the motor shaft and a pair of spaced parallel shafts the ends of which project from the housing and about which the wheel swinging arms are rotatable and means on the ends of the shafts for driving the wheels of the wheelsets.
An embodiment of the invention is now described by way of example with reference to the drawings in which: Figure 1 is a half sectioned side elevation of the bogie of the invention, and Figure 2 is a half sectioned end elevation of the bogie of Figure 1.
The bogie of the invention is shown in the drawings to consist of a prime mover 10, a housing 12 and a wheel set consisting of four rail wheels 14, only two of which are seen in the drawings.
The housing 12 is a gearbox which contains three meshed gears 16, 18 and 20. The gear 18 is a bevel gear which carries a fixed reduction pinion gear 22 which is meshed with the spur gears 1 6 and 20 as seen in Figure 1. The gears 16 and 20 are each mounted on the shaft 24 which is journalled for rotation in and projects from bearings in the side walis of the housing. The four ends of the gear shafts on the outside of the housing each carry a fixed chain sprocket 26.
The prime mover 10, which in this embodiment of the invention is a D.C. traction motor, is fixed vertically on the housing 12 with a beveled pinion gear 28 on the end of the motor rotor shaft meshed directly with the beveled gear 1 8.
The wheels 14 are each mounted on a swinging arm 30 which is mounted on and pivotable about a boss which houses the bearings of the shafts 24 on the outside of the sidewall of the gearbox housing. The arms include any suitable suspension means, not shown, for holding them in the position shown in the drawings. A suitable suspension arrangement could consist or rubber or like shock dampers which are located between suitable formations on the arms 30 and the housing 12 to bias the arms downwardly.
The wheels each carry a fixed chain sprocket 32. A suitable drive chain 34 connects each gear shaft sprocket 26 to a wheel sprocket 32. The chains could each be located in a suitable chain cover 35 for protection and safety.
Each of the shafts 24 to which the gears 1 6 and 20 are fixed carry, in the gearbox housing, discs of a wet disc brake 36 which is adapted for activation from the outside of the housing 12.
The sump of the housing 12 is fiiled with oil for lubrication of the gears and brakes 36.
The upper surface of the housing 12 carries either a fixed or swivelable turntable 38 which is adapted for attachment to the bed of a vehicle on which the bogie is to be used.
As will be appreciated from the drawings arld their description, the purely mechanical drive coupling between the motor 10 and the wheels will eliminate synchronisation problems which are common with arrangements of this sort which employ independently driven wheels.
The invention is not limited to the precise constructional details as herein described and the prime mover 10 could, for example, be a hydraulic motor in place of the electrical motor described above. Additionally, the wheel chain drives could be replaced by geared drives.
1. A vehicle bogie including a housing which carries a wheelset, means for connecting the housing for rotational motion on a vertical axis to a vehicle body, a prime mover and power transmission means connecting at least one wheel of the wheelset to the prime mover.
2. A bogie as claimed in claim 1 in which at least a portion of the transmission means is located in the housing and the prime mover is a motor which is located above the vehicle body connecting means with the rotor shaft of the motor being vertically located in the housing on its axis of rotation and engaged with the transmission means.
3. A bogie as claimed in claim 2 in which the wheelset includes two pairs of wheels.
4. A bogie as claimed in claim 3 in which at least one wheel of each pair is connected through the transmission means to the rotor shaft of the motor.
