The drive units 50 and 51 are electric connected in series and thus act as a differential for the wheels of the front Wheel frames. As will be described in detail later, the motor drive 50 drives the Wheels 52 and 53 on one side of the frame 23. The motor drive 51 drives wheels 54 and 55 on the opposite side: the front wheel frame 23 on. By the fact that the drive units 50 and 51 are connected in series drive these the corresponding wheels at the same speed. When the transport ' However, if the vehicle is in a curve, the wheels will turn on the shorter one Side of the curve slower while the wheels are on the longer side of the curve turn faster.

The electrical connection between the drive units is made possible a drive unit to slow down as it is according to the shorter to be covered Distance is required. When referring to Fig. 2, the transport vehicle in a right curve goes, then the wheels 54 and 55 rotate more slowly as a result of the slower one Drive by the drive unit 51. As a result of the motor series connection, the / drive 50 automatically faster to the same amount so that wheels 52 and 53 move Turn faster to make the curve with a larger radius.

A cam roller or guide roller 71 is rotatable on each arm 70 arranged so that the outer peripheral surface of the roller 71 is close however is at a distance from the side edge of the rail 43. When the rails of the rail system going straight ahead, the rollers 78 will not engage the sides of the rails.

However, if the rails describe a curve and the vehicle is in the curve goes, then the guide roller 71 comes into rolling engagement with the Edge of the rail on the outside of the curve.-The role of the guide rollers 71 is therefore to turn the wheels behind you to avoid excessive wear on the rail and on the inside of the flange 72 on the wheel. the Rollers 71 take on the main deformation forces between the curved rail and the heavy transport vehicle and thus ensure contact between the wheels of the transport vehicle and the rails, which are proportionate is free from deformation forces and from wear and tear.

It is within the scope of the invention to have a rear arm and to provide a rear guide roller for each housing to enable the transport vehicle can move back and forth for certain applications to create a similar, to provide free movement of the vehicle wheels from deformation forces while moving the vehicle moves backwards.

As shown generally in the drawings, the transport vehicle an articulated suspension system is provided which ensures contact with eight wheels on the rails takes place simultaneously. As shown in Fig. 6, pins 73 connect the individual wheel frame assemblies 73a with the underframes 23, so that each wheel set 52 and 53 and 54 and 55 automatically adjusts even with unevenness and changes in height of the rail system. the Wheels 65 and 66 and 67 and 68 are attached to the base 24 in a similar manner. Furthermore, the rear subframe 24 can be pivoted with the aid of a pin 74 a rear radial bearing 76 connected to an additional automatic self-adjustment Provide for changes in the alignments of the rails or other rail irregularities to compensate that occur as a result of inaccurate installation or heavy loads can.

The transport vehicle is given additional adaptability by radial ball bearing assemblies 75 and 76 that support the front and rear undercarriages Connect 23 and 24 to the support frame 22. These camps improve the possibility of the transport vehicle to take the load off-center.
