Dongfeng Xinjiang D1 truck spare parts cab shell 50M12-SBS604ZXY

Adopting a “full-enclosed safety cage” design, this cab shell prioritizes driver safety with multi-level structural reinforcement. Key stress-bearing parts including A-pillars, B-pillars, roof crossbeams, and floor beams are made of Q960 high-strength steel with a tensile strength of 960MPa, which is 45% stronger than ordinary Q355 steel. The floor adopts a 4-layer composite structure (base steel + anti-collision ribs + buffer foam + wear-resistant plate) that can withstand a 12-ton impact load without collapsing. It meets ECE R29-03 rollover safety certification, maintaining a valid survival space for drivers even when the cab rolls over at 35km/h. The front anti-collision beam is integrated with energy-absorbing aluminum honeycomb structures, which can reduce frontal collision impact force by 55%, significantly improving accident survival rates

The cab shell achieves an optimal balance between lightweight and structural rigidity through advanced material matching and structural optimization. It adopts a hybrid material scheme: 40% of the structure uses Q960 high-strength steel for stress-bearing areas, and 25% uses 6063 aluminum alloy for non-stress panels such as side walls and roofs, reducing the overall weight by 20% compared to traditional all-steel cabs—directly improving fuel efficiency by 6-8%. The shell undergoes CNC precision stamping and robotic laser welding (weld seam strength ≥520MPa), ensuring uniform force transmission and minimizing cab vibration during driving. Finite element simulation tests confirm that it can resist torsional deformation under 35g vibration loads (5-2000Hz) and maintain structural integrity even when driving on uneven mining roads, enhancing driving stability

Tailored to the harsh operating environments of Xinjiang and western plateau areas, the cab shell features specialized environmental adaptation designs. The aerodynamic contour optimized by CFD simulation has a 28° sloped windshield and streamlined roof deflector, which can reduce wind resistance by 28% at high altitudes (where wind speeds are frequent) and lower wind noise by 18dB. The shell’s sealing system uses high-temperature and low-temperature resistant EPDM rubber (operating range -45℃ to 85℃), achieving IP67 waterproof and dustproof ratings, effectively preventing sand intrusion in desert areas and water seepage in heavy rain. The surface undergoes a three-layer anti-corrosion treatment (zinc phosphating + electrophoretic coating + powder coating) with a total thickness of 130μm, passing 3000-hour neutral salt spray tests to resist corrosion in saline-alkali areas of Xinjiang

Designed for both factory assembly and after-sales maintenance, the cab shell adopts a modular structure with precise positioning benchmarks. All pre-punched holes for interior components, wiring harnesses, and exterior accessories have a dimensional tolerance of ±0.08mm, ensuring one-time accurate alignment during assembly. It integrates standardized mounting interfaces for plateau-specific configurations such as oxygen generators, heating systems, and anti-freeze air conditioners, reducing assembly time by 35% compared to non-OE shells. For after-sales service, the shell’s detachable front panel and side inspection doors allow quick access to the engine and chassis components, shortening maintenance time by 50%. Backed by a 3-year/350,000km warranty, it provides reliable support for long-term heavy-duty operations in western China
