Motor-Wheel Reduction Gear Unit
The motor wheels of the dump truck are fully unified, which allows to optimize the range and number of spare parts and reduce operating costs.
Bearing parts and gears of the motor-wheel reduction gear unit are made of the top-of-the-line alloy steels according to the most sophisticated technologies.
The applied kinematic scheme allows to transmit torque to the wheel hub simultaneously by the first and the second rows of the reduction gear unit and maximize the use of the space inside the wheel rim, reduces the actual loads in the reduction gear unit and provides its insreased service life.
The design of the reduction gear unit is made in such a way that replacement of any part is possible without dismantling the tires, which reduces the time for its maintenance and repair.
The design of the motor-wheel reduction gear unit made it possible to use the hub seals of reduced diameter, which reduced the sliding speed and increased its reliability and service life. For the same purpose, the grease supply system for the hub seals is installed, connected to the centralized lubrication system of the truck.
Design solutions of the reduction gear unit eliminate the influence of deformations of gears and bearings of the unit that may occur during operation which makes it reliable and durable.
