Description

Technical Field

[0001] This utility model relates to the field of fatigue loading test technology for vehicle vibration damping joints, and specifically provides a torsional loading device for a commercial vehicle thrust rod system. Background Technology

[0002] The commercial vehicle chassis thrust rod system is a key guiding and force transmission mechanism connecting the frame and axle. Especially in heavy trucks, tractors, buses and other models, it plays a decisive role in the stability, handling and load-bearing capacity of the vehicle. The commercial vehicle chassis thrust rod system is a key force transmission and load-bearing device of the vehicle chassis, and its durability and reliability are directly related to the service life and safety of the vehicle.

[0003] Verifying the durability of a commercial vehicle chassis thrust rod system during its development phase is crucial for ensuring performance and overall vehicle stability. During testing, to ensure the results closely match real-world conditions, laboratory conditions are typically required to closely mirror actual usage. However, due to the unique characteristics of thrust rods, their stress conditions during actual operation are complex. Vehicle starting, braking, cornering, and wheel bounce caused by traversing uneven roads result in the thrust rod being subjected to vertical, lateral, longitudinal, and yaw loads simultaneously. Yaw loads require detection using a torsional loading device.

[0004] Existing technologies for torque loading devices in thrust rod systems suffer from excessive sway angles, which may cause interference. Therefore, designing a torque loading device for commercial vehicle thrust rod systems that can avoid excessive sway angles and thus ensure detection performance is an urgent problem to be solved.

[0008] Furthermore, both longitudinal plates extend upwards toward the thrust rod system to form an extension section. The extension section and the transverse plate near the thrust rod system together form a receiving area, and the support plate is located within the receiving area.

[0009] Furthermore, the end of the main shaft near the thrust rod system is connected to the support plate; the longitudinal width of the support plate is greater than the longitudinal width of the bearing housing, and a wobble gap is left between the support plate and the extension section.
