Problems solved by technology

As the main transmission mechanism of the electric wheel dump truck, the wheel side gear device occupies an important position in the electric wheel dump truck. The wheel side gear device is installed inside the rim and needs to transmit large power. It also bears the load of the vehicle while transmitting torque. Due to the limited internal space of the rim, the existing wheel gear device is inconvenient to install due to the alternating load of weight, and the lubrication effect is poor, and the bearing capacity is not good enough

The hub assembly, the wheel rim gear device and the dumper comprise the transmission device.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a transmission device, a wheel hub assembly, a wheel side gear device and a dump truck. Background technique [0002] Mining electric wheel dump trucks are transportation vehicles for open-pit coal mines, metal mines and water conservancy projects. They are usually powered by diesel engines, converted into electrical energy through generators, and transmitted to electric motors after frequency conversion control, and converted into high-speed and low-torque loads , and through the wheel gear device to reduce speed and increase torque, to obtain a low-speed high-torque load that can drive the vehicle forward. As the main transmission mechanism of the electric wheel dump truck, the wheel side gear device occupies an important position in the electric wheel dump truck. The wheel side gear device is installed inside the rim and needs to transmit large power. It also be...
