Embodiment Construction

[0023] dump truck 10 shown on figure 1 middle. These are so-called large dump trucks, which are used, for example, in mines. Front wheel 14 and trailing wheel 16 are driven by electric motor (in figure 1 not shown in more detail) driven, supported at a rigid frame. The rear wheels 16 are designed to have dual tires (see figure 2 ).

[0024] The hopper 18 is pivotally connected to the frame and is pivotable by hydraulic lift cylinders provided at both sides of the vehicle. The vehicle 10 is delimited by a bumper 22 in the region of the front of the vehicle in the direction of travel. The radiator module 24 is arranged above the bumper 22 . The upper deck 26 extends across the width of the dump truck 10 above the radiator module 24 . The operator's cabin 28 is located on one side of the upper deck 26 , on the side of the upper deck 26 to the left in the direction of travel. The operator's compartment 28 is thus above the left front wheel 14 .

Abstract

The invention relates to a work machine, in particular in the form of a dump truck or truck, having a diesel electric traction drive, wherein at least one alternator is or can be driven by at least one internal combustion engine of the work machine. In accordance with the invention, the current generation can also be reliably interruptible with a running internal combustion engine by interruption of the excitation circuit by means of a breaker switch.

Description

technical field [0001] The invention relates to a work machine, in particular in the form of a dump truck or truck, with a diesel-electric drive, wherein an alternator is or can be driven by at least one internal combustion engine of the work machine. Background technique [0002] Dump trucks or so-called jumbo dump trucks are mainly used in coal mining operations or mining operations to transport mined coal, minerals and ores. These bulk self-dumping equipment are manufactured in sizes greater than 90 metric tons (tons) in weight and payload, up to hundreds of tons, giving them a great overall size. [0003] Diesel-electric drives are used as traction drives, wherein the mechanical energy produced by such diesel engines is converted into electrical energy with the assistance of an alternator to supply the electric traction drives. The reason for this process is that diesel engines, like all internal combustion engines, can only be operated with ideal efficiency within a ve...
