Dongfeng VR truck parts left Tilt bracket with Rubber Bushing Assembly 5001025-C1100

Designed to work in tandem to absorb vibration and enable smooth cab movement, the assembly combines a rigid tilt bracket with a high-performance EPDM rubber bushing. The rubber bushing (72 Shore A hardness) features a dual-layer structure: an inner metal sleeve for pivot pin compatibility and an outer rubber layer that absorbs 70% of vibration from the chassis, preventing metal-to-metal rattling in the cab during driving. It also reduces friction between the bracket and pivot pin by 60%, requiring only 80N of force to actuate cab tilting (25% less than worn assemblies). The bushing’s flexible design allows ±4° of angular movement, accommodating minor chassis flex without stressing the bracket. Unlike brackets with rigid plastic bushings that cause rough operation, this synergetic design improves operator comfort and extends the lifespan of the entire tilt mechanism

Built to withstand the high torque and static loads of cab tilting (supporting up to 40% of the Dongfeng VR’s cab weight), the tilt bracket is crafted from 40Cr alloy steel—heat-treated to HRC 40–44 for exceptional tensile strength (1,000 MPa) and impact resistance (27 kJ/m²). The bracket undergoes precision forging and robotic welding to create a seamless, reinforced structure, with 10mm-thick gussets at stress points (e.g., bushing housing, mounting hole edges) to distribute load evenly. Finite Element Analysis (FEA) testing confirms the bracket endures 6,000+ cab tilt cycles (equivalent to 9 years of heavy use) without fatigue cracking, even under uneven loading. Unlike low-carbon steel brackets that bend under stress, this high-strength design ensures reliable cab support and smooth tilting throughout the truck’s service life

Engineered to resist corrosion from underbody contaminants (road salt, mud, moisture) and wear from pivot movement, the assembly features dual protective treatments. The tilt bracket’s surface is coated with a zinc-nickel alloy (18μm thickness)—providing 15x better corrosion resistance than standard zinc plating—passing 1,200 hours of neutral salt spray testing without rust. The bracket’s bushing housing is precision-machined to a Ra 0.6μm surface finish, reducing friction with the rubber bushing and preventing premature wear. The EPDM rubber bushing is infused with UV-stabilizers and oil-resistant additives, maintaining flexibility for 8+ years and resisting hardening or cracking from sun exposure or diesel spills. Unlike uncoated brackets that rust or wear quickly, this dual-protection design ensures the assembly remains functional in rain, snow, or dusty off-road conditions

Designed for hassle-free replacement by fleet technicians or DIY owners, the assembly arrives fully pre-assembled—the rubber bushing is factory-pressed into the tilt bracket, eliminating the need for specialized pressing tools. It includes all necessary hardware: 4 M12×35mm high-tensile bolts, lock washers, a tube of anti-seize compound (for the pivot pin), and a torque guide (specifying 75 N·m for secure mounting). Installation takes 25–30 minutes: support the cab with a hydraulic jack, remove the old bracket by unscrewing frame bolts and sliding out the pivot pin, clean the pivot pin and mounting surfaces, slide the new assembly onto the pin, align mounting holes with the frame, torque bolts to specification, and apply anti-seize to the pivot pin. No post-installation adjustment is needed—the pre-assembled bushing ensures proper alignment with the tilt system. Each unit undergoes dimensional verification via CMM, load testing, and bushing fit checks, backed by a 24-month warranty against defects (e.g., bracket bending, bushing cracking, corrosion)
