Description

Technical Field

[0001] The utility model belongs to the technical field of range extender suspension, in particular to a range extender suspension device for a mining truck. Background Art

[0002] A mining truck is a heavy-duty dump truck used in open-pit mines to complete rock and earth stripping and ore transportation tasks. Its working characteristics are short distance and heavy load. It is usually loaded with a large electric shovel or hydraulic shovel and travels back and forth between the mining point and the unloading point.

[0003] A range extender generally refers to an electric vehicle component that can provide additional electrical energy, thereby increasing the mileage of the electric vehicle. A range extender in the traditional sense refers to a combination of an engine and a generator.

[0004] Traditional fuel mining trucks have a relatively mature way of fixing their engines. However, because the engine is directly connected to the generator, the peak torque of the motor is large and converts rapidly in a certain speed range. The torque will reverse from positive to negative in a very short time. As a result, the requirements for the load, torque, vibration isolation and various stability that the range extender suspension system can withstand are constantly increasing.

[0005] At present, there are two types of range extender suspension for mining trucks:

[0006] 1. Only the engine support point is fixed, the generator is directly connected to the engine, and there is no suspension system to fix the generator. When the generator is subjected to a large torque, it will have a large torsion and a large vibration amplitude.

[0007] 2. The engine and generator are fixed separately. Under bumpy and complex working conditions, the amplitudes of the engine and generator are different, which causes great damage to the gear direct connection and poor overall stability of the range extender. Utility Model Content

[0011] A further improvement of the utility model is that a first gasket is provided on the upper side of the first rubber shock-absorbing block on the upper side.

[0012] A further improvement of the utility model is that a second gasket is provided on the upper side of the second rubber shock absorbing block on the upper side.
