Sinotruk Howo 7 Howo Chassis Braking Device (Non-Traction / 6×4 / 275 / Model 16)
The Sinotruk Howo 7 Howo Chassis Braking Device is a complete air brake system specifically designed for non-traction 6×4 configuration Howo 7 trucks, featuring 275mm brake chambers and Model 16 specifications. This comprehensive system begins with the air drying chamber (WG9000360521) that removes moisture and contaminants from the compressed air, ensuring clean, dry air reaches all braking components. The system includes mounting hardware such as the drier bracket (WG9918360817) and hexagon bolts with flange (ZQ1851440) that provide secure installation and vibration resistance in demanding operating conditions.
Air storage and distribution form critical components of the Sinotruk Howo 7 Howo Chassis Braking Device, with multiple air reservoir assemblies including 40L (WG9000361714) and 30L (WG9000360715) units that provide ample compressed air storage for reliable brake application. The four-circuit protective valve (WG9000360523) ensures balanced air distribution to different brake circuits, maintaining system integrity even if one circuit fails. These components work together to provide consistent air pressure for immediate brake response when needed.
The connection and routing system of the Sinotruk Howo 7 Howo Chassis Braking Device includes numerous joints, pipes, and protective elements that ensure reliable air flow throughout the system. Various straight-through and right-angle joint bodies in NG12, NG8, NW12, NW9, and NW6 configurations provide flexible connection options, while spiral protective pipes, corrugated sheaths, and rubber sheaths protect air lines from damage. Plastic fastening belts and stringing sheaths ensure proper routing and secure mounting of all components.
Maintenance and safety features are integral to the Sinotruk Howo 7 Howo Chassis Braking Device, with drain valves (WG9000361402) allowing for regular removal of accumulated moisture, and pressure test joint assemblies (WG9000361401) facilitating system diagnostics. The comprehensive hardware package includes various bolts, nuts, washers, pins, and brackets that ensure proper installation and long-term reliability. This complete system represents Sinotruk’s commitment to safety and performance in heavy-duty commercial vehicle applications.
