Structural Form:

• Made of cast steel/cast iron (gray coating for rust prevention and wear resistance).

• Triangular/fork-shaped bracket structure with a mounting flange at the bottom (with multiple bolt holes) for rigid connection to the axle housing or rear axle body.

• A bearing housing cavity (circular raised area) in the middle for installing the balance shaft bearing and supporting the rotation of the balance shaft.

• A leaf spring seat (with a U-shaped groove or protrusion) on the side for fixing the shackle of the rear axle leaf spring and transmitting vertical loads.

Quantity and Application Scenario:

• These are presumed to be new parts awaiting assembly or replacement parts for maintenance, commonly used in rear axle repairs or vehicle assembly for heavy-duty trucks (e.g., Shaanxi Automobile Delong, Foton, FAW Jiefang, etc.).

Related System:

• The balance shaft housing is the core component of the balance shaft suspension system.

• The balance shaft passes through the bearing housing of the housing, with both ends connected to the wheels (or wheel ends).

• Through the combination of the balance shaft and leaf springs, it counteracts lateral forces during vehicle operation, distributes loads, prevents single-wheel overloading, and improves ride comfort and safety under heavy-load conditions.
