howo dump truck spare parts Ingot-shaped beam connector AZ972551000009/AZ972551000008
Commonly found in the front or middle suspension systems of heavy-duty vehicles such as the Howo 70 mining truck, 84 mining truck, HOWO-T7H, and HOWO-A7.
Function
1. Connecting and securing the balance beam (equalizer beam): As the core mounting base of the balance beam, it reliably connects the balance beam to the vehicle frame or suspension longitudinal beam, forming a complete balanced suspension system.
2. Achieving balanced axle load distribution: Through the swinging characteristics of the balance beam, the load is evenly distributed between the front and rear axles (or multiple axles), preventing single-axle overload and improving the vehicle's passability and stability under heavy loads and on uneven roads.
3. Withstanding enormous vertical loads and torque: Under full load conditions (50-100 tons) of mining trucks and heavy-duty dump trucks, it withstands tens of tons of vertical pressure, lateral force, and torsional force, ensuring that the suspension system does not fail.
4. Buffering and shock absorption: In conjunction with balance beams, leaf springs, pins, and bushings, it absorbs and transmits road shocks and vibrations, protecting the frame, cargo box, and cab, and extending the service life of the entire vehicle.

Advantages
1. Superior Load-Bearing Capacity and High Load Adaptability: Designed specifically for mining/construction vehicles weighing 70 tons or more, each component can withstand tens of tons of vertical load plus lateral torque. It supports balanced axle load distribution under full load (or even overload) conditions, preventing premature failure caused by overloading on one side or one axle.
2. Excellent impact resistance and deformation resistance: The structural design incorporates multiple reinforcing ribs and thickened stress-bearing areas (key wall thickness of 30–50mm), effectively dispersing stress concentrations. Under extreme conditions such as uneven roads, sudden braking, and heavy-load starting, the deformation is minimal, and it is not prone to cracking or permanent deformation.
symptom
1. Obvious abnormal noise while driving: The chassis makes abnormal noises when driving over potholes or uneven roads, especially during starting, braking, or turning.
2. Vehicle pulling to one side or steering wheel shaking: The steering wheel needs to be corrected when driving in a straight line; the steering wheel shakes at high speeds. The chassis feels soft and unstable.
4. Abnormal tire wear: Uneven wear of tires on the front and rear axles, indicating uneven axle load.
5. Signs of loose leaf springs or U-bolts: Inspection reveals loose U-bolts connecting the leaf springs to the mounting brackets, worn or displaced washers.
Troubleshooting suggestions
1. Immediate Replacement: When serious malfunctions occur, such as cracks/deformation/breakage of the connecting seat, detachment of the balance beam, severe vehicle deviation, or loud metallic banging sounds from the chassis, the vehicle must be stopped immediately and the faulty part replaced to prevent safety accidents or cascading damage to the frame, leaf springs, balance beam, etc.
2. Recommended Proactive Replacement: When moderate malfunctions occur, such as noticeable abnormal noises accompanied by vehicle deviation, looseness of the balance beam, uneven tire wear, or signs of loose leaf spring U-bolts, replacement should be arranged as soon as possible, usually within 1-2 weeks of detection.
3. Preventive Replacement:
For mining trucks/heavy-duty dump trucks, after 80,000-120,000 kilometers of use or 3-5 years of service; in cases of prolonged overloading (70 tons+) and frequent operation on harsh road surfaces (gravel, potholes, steep slopes); or when inspection during regular maintenance reveals ovalization of the pin holes, fine cracks on the surface, or signs of deformation; if either side shows problems, it is strongly recommended to replace both sides as a pair. Even if the other side appears normal, it is likely to fail quickly due to uneven stress distribution.
