(3) Steering transmission mechanism
The steering motor drives meshing gears and then is transmitted to steer wheel. The
steering way is simple, easy and convenient. (Refer to the chapter relating to steering axle
for more information).
3.4 Integrated electric steering axle
The steering rear axle assembly (as shown in Figure 3-2) is composed of steering
motor, mechanical structure (including reductor), steering wheel axle and steer wheels
and other parts. The meshing gear pair is driven by the steering motor. When the driver
operates the steering wheel, the angle signal is provided to the controller, which gives the
control signal to the steering motor. The steering motor outputs a steering torque through
the mechanical structure to control the truck steering. The wheel is pried to the rear wheel
hub through the wheel rim, and the rear wheel hub is installed on the steering wheel axle
through two tapered roller bearings; the inner side of the bearing is equipped with oil seal
to keep the grease in the wheel hub and the steering wheel axle cavity.
Steering axle tyre and rim model see table 3-1.
