HOHAN N7 HOHAN NJ17 Steering shaft and Steering column assembly WG9525470087 WG9525470121
The core components of the entire steering column system-including the mounting bracket, adjustment mechanism, ball screw, and universal joint-are responsible for transmitting the driver's steering inputs to the steering gear.
FUNCTION
1. As the core intermediate transmission component of the cab's steering system, it precisely transmits steering inputs from the steering wheel to the lower telescopic shaft and steering gear; by conveying the steering torque applied by the driver to the steering gear, it facilitates vehicle steering control.
2. Telescopic Adjustment Function: Features axial adjustability, allowing for a comfortable driving position tailored to drivers of varying physical statures.
3. It absorbs minor vibrations and displacements occurring during the steering process, thereby protecting other components of the steering system and minimizing abnormal noises and wear.
Installation Location
1. The steering column assembly is mounted inside the cab, positioned centrally beneath the instrument panel; its upper end connects directly to the steering wheel (via splines or mounting bolts), while its lower end connects to the telescopic shaft via a flange or coupling component.
2. The steering telescopic shaft is installed as an extension beneath the steering column assembly, serving to connect the lower end of the steering column assembly to the input shaft of the steering gear.
Working Principle
Together, these components constitute the steering column system. Its core function is to accurately and safely transmit the rotational torque and angular input applied by the driver at the steering wheel to the steering gear located below, thereby ultimately controlling the steering of the front wheels.
Advantages
| Performance Dimension | WG9525470087 (Telescopic Steering Shaft) Performance Advantages | WG9525470121 (Steering Column Assembly with NJ17 Ball Screw) Performance Advantages | Overall Performance Advantages of the Two Parts Combined |
|---|---|---|---|
| Steering Lightness | Reduces sticking through telescopic structure and improves overall system smoothness | NJ17 ball screw adopts rolling friction, significantly reducing steering resistance for lighter and smoother operation (far superior to traditional sliding friction) | The combination delivers a "light + smooth" feel, reducing operating effort on long-distance drives and minimizing driver fatigue |
| Control Precision | Universal joints + spline design ensure efficient torque transmission with good backlash control | Ball circulation mechanism provides high transmission accuracy and low backlash, enabling faster and more accurate steering angle response | Precise force transmission + low backlash results in linear steering feel and more stable control at high speeds or under full load |
| Adaptability & Compensation | Excellent telescopic (telescopic) capability automatically compensates for relative movement between cab and chassis (adapts to floating suspension and bumps) | Adjustment mechanism supports flexible height/angle adjustment to suit different driving postures | Rigid-flexible combination: upper section for comfortable adjustment, lower section for telescopic compensation, adapting to complex heavy-truck conditions (bumps, load changes) |
| Vibration & Noise Control | Telescopic structure + dust-proof bellows effectively absorbs minor vibrations, reducing steering wheel shake and abnormal noise | Low-friction ball screw design reduces mechanical noise and vibration transmission | Overall low vibration and minimal abnormal noise, improving driving smoothness and comfort |
