The precise control of heavy-duty truck trolley steering systems mainly involves the following key aspects:
1. High-quality steering mechanism design
Steering gear selection: Heavy-duty vehicles often use power steering gears, such as hydraulic power steering gears. It provides auxiliary power through the hydraulic system to reduce the force of the driver operating the steering wheel. This kind of steering gear has a precise gear rack or recirculating ball structure inside. Take the recirculating ball steering gear as an example. It has a steel ball installed between the screw and the nut, which converts sliding friction into rolling friction, reduces steering resistance, and improves steering accuracy.
Steering transmission device optimization: The steering transmission device includes steering rocker arms, straight tie rods, and tie rods. The connection points of these components use ball joints, which can rotate flexibly in multiple directions to ensure the effective transmission of steering force. In addition, during the manufacturing process, the dimensional accuracy requirements are very high. For example, the length tolerance of the tie rod is controlled within a very small range to ensure the accuracy of the steering angle of the left and right wheels.
2. Advanced electronic control system assistance
Sensor application: The torque sensor installed on the steering shaft can accurately measure the magnitude and direction of the torque applied by the driver to the steering wheel. At the same time, the angle sensor at the wheel can monitor the steering angle of the wheel in real time. These sensors transmit signals to the electronic control unit (ECU).
Electronic Control Unit (ECU) adjustment: The ECU calculates according to the signals from the sensors and the pre-set program. If a steering angle deviation is detected, it will control the power assist motor or hydraulic system to fine-tune the steering.
3. Professional operation and adaptation of the driver
Skill training: Drivers need to undergo professional training and be familiar with the characteristics of heavy-duty vehicle steering systems. They need to understand how to properly control the steering wheel angle and force under different road conditions and vehicle speeds.
Adapt to vehicle characteristics: The steering system of each heavy-duty vehicle may have slight differences. The driver must adapt to the vehicle's steering feel, response speed and other characteristics during driving, and accumulate experience to better achieve precise control.
