Description

Technical Field

[0002] A generator is a mechanical device that converts mechanical energy into electrical energy. It is driven by a turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator, which is then converted into electrical energy by the generator. Traditionally, if we want to use a generator on a vehicle, we usually install the generator set on the vehicle, or use a power take-off to transfer the generator and the vehicle power. The generator set takes up a lot of space. It is only suitable for use in larger vehicles. The power take-off generator connects the original power on the vehicle to the generator through a power take-off. The disadvantage is that in order to ensure that the speed of the generator does not change, it can usually only be used when the vehicle is parked. The hydraulic generator solves the above problem very well.

[0003] The above-mentioned prior art still has some problems: 1. It is difficult to connect the hydraulic docking permanent magnet generator to the hydraulic motor.
