I. Product Overview
This engine mount base is a core component of heavy truck vibration isolation systems, precision cast from high-quality cast steel. Designed to securely mount the engine to the vehicle chassis, it effectively absorbs and buffers engine vibration and shock, reduces noise transmission, protects the engine and chassis from damage, and ensures smooth, stable operation of heavy-duty vehicles under heavy load and complex road conditions. We also provide professional rubber vulcanization services to deliver fully assembled, ready-to-install engine mount assemblies.
This engine mount (hereinafter referred to as the "mount" a core load-bearing component of the powertrain suspension system, achieves three core functions: stable engine fixation, vibration isolation, and load transfer, through an integrated design of metal structures and elastlements. The product strictly adheres to national and industry standards such as GB/T 38597-2020 "Road Vehicles - Powertrain Suspension Systems - Terms andDefinitions" and QC/T 545-2022 "Automotive Engine Suspension System - Bench Test Methods," while also meeting the requirements ofthe IATF 16949 quality management system. It is suitable for fuel, hybrid, and electric powertrains in passenger cars, commercial vehicles, and special vehicles, serving as a key nt to ensure the overall vehicle's NVH performance, driving comfort, and power system durability.
Key Material & Performance Advantages
Premium Material Specification
Chinese Grade: ZG310-570 Carbon Cast Steel
US ASTM Equivalent: ASTM A27 Gr. 60-30
European EN Equivalent: EN 10213 GSC250
Core Advantages: Excellent strength, toughness and load-bearing capacity, meeting the harsh working requirements of heavy truck engine mounting systems, with outstanding impact resistance and fatigue resistance.
II. Core Advantages
1. High-Strength Load-Bearing Design Material Selectiovides multi-material solutions, including QT450/QT500 ductile iron, A356-T6 aluminum alloy, Q235 high-quality carbon strucl steel, and carbon fiber composites, to meet the strength and lightweighting requirements of different vehicle models. Among them, the aluminum alloy mount uses an optimized Al-Ti-C-Bi composfier formula, achieving a tensile strength ≥320MPa and Brinell hardness ≥95HB, reducing weight by over 40% compared to traditional materiby assisting in improving the vehicle's fuel economy. Structural Reinforcement: Adopts a three-point/four-point distributed support layout with triangular reinforcing ribs between the mount body an the baffle. Installation holes precisely match the engine block and vehicle subframe, ensuring no displacement or fracture during sudden acceleration, emergency braking, and bumpy road conditions, with a fatigue ife of over 500,000 loading cycles.
2. Excellent Vibration and Noise Reduction Performance Integrates high-damping rubber bushings or hydraulic cushioning modu, capable of absorbing 40%-60% of high-frequency vibrations generated by engine operation. Dynamic stiffness control precision is ±8%, with a decoupling rate ex effectively reducing cabin noise and idle vibration. Elastic elements use high/low temperature resistant formulations, maintaining performance stability under temperature cycles from -40°C to 125°C, suitable for complex operating environments.
3. Precision Manufacturing and Reliable Quality Adopts differential pressure casting, integrated die-casting, and electrophoretic coating processes. Surface ent of metal mounts is optimized according to material characteristics: non-machined surfaces of cast iron parts are painted black, machined surfaces are coated with rust preventive oil; aluminum alloy parts ergo shot peening; carbon structural steel parts use electrophoretic black paint or white zinc trivalent chromium treatment, with salt spray test corrosion resistance reaching over 48 hours. Be leaving the factory, the product undergoes CAE mechanical simulation analysis, modal testing (1st order modal ≥200Hz), and road reliability testing to ensure no loosening oment failure modes.
