Engine Bracket Assemby for HOWO A7 8X4 Trucks

The Beam assembly forms the primary load-carrying structure of the engine mounting system. This tubular cross member connects the left and right frame rails and provides a rigid platform for attaching the engine support brackets.

Constructed from high-tensile steel, the Beam assembly resists bending and torsion while maintaining a lightweight profile. Its precise dimensions ensure a perfect fit with the chassis mounting points.

This component is designed to absorb and distribute dynamic loads from the engine, reducing stress on individual fasteners and prolonging the life of the entire bracket system.

The Self-locking screw provides a secure, vibration-resistant fastening solution for critical joint locations. Its unique thread geometry creates a prevailing torque that prevents loosening under cyclic loading.

Made from alloy steel with a durable surface treatment, the Self-locking screw maintains its clamping force even after repeated thermal cycles and mechanical shocks.

This fastener is essential for maintaining the integrity of the Engine bracket assemby, as it eliminates the need for additional locking compounds or adhesives.

The Hex bolt is a versatile fastening element used throughout the Engine bracket assemby to secure brackets, subplates, and mounting flanges. Its six-sided head enables high torque application with standard wrenches.

Available in various lengths and diameters, the Hex bolt is manufactured from quenched and tempered steel to provide exceptional shear and tensile strength.

Each Hex bolt is precision-threaded and coated to resist galling and corrosion, ensuring reliable performance and easy removal during maintenance.

The Subplate serves as an intermediary mounting surface that distributes loads from the engine supports to the main frame. It increases the bearing area and reduces stress concentration on the chassis rails.

Fabricated from thick steel plate and machined to tight tolerances, the Subplate accommodates minor alignment variations while maintaining a solid connection interface.

This component also provides additional mounting points for ancillary equipment, adding versatility to the overall engine compartment layout.

The Bracket assembly is a welded structure that directly supports the engine mounts and transfers vertical and lateral forces to the chassis. Its robust design minimises deflection and maintains engine alignment.

Using high-strength steel and reinforced gussets, the Bracket assembly withstands the high static and dynamic loads generated by the engine and transmission.

This assembly is engineered for easy installation and removal, allowing for efficient service access without disassembling adjacent components.

The Hex flange face bolt(fine thread) combines a built-in flange washer with a fine pitch thread, providing superior clamping force and resistance to self-loosening. The flange distributes load over a wider area.

This bolt is ideal for applications with limited space or where precise torque control is critical. Its fine thread offers higher preload accuracy and better fatigue resistance.

Used in high-stress locations, the Hex flange face bolt(fine thread) ensures a durable and vibration-proof connection within the Engine bracket assemby.

The Motor rear support right bracket assembly is a dedicated bracket that anchors the rear right side of the engine to the frame. It handles the torsional reactions from the driveline.

Precision-formed from heavy-gauge steel, this bracket incorporates bushings and reinforcement ribs to absorb shock loads and reduce noise transmission.

Its symmetrical counterpart on the left side works in tandem to maintain perfect engine alignment and minimise stress on the crankshaft and transmission.

The Hex flange face bolt is a general-purpose fastener with an integrated flange that eliminates the need for a separate washer. It provides a clean, compact assembly with reduced parts count.

Manufactured from medium-carbon steel and heat-treated, this bolt offers excellent strength and ductility. Its flange also serves as a locking feature under high vibration.

This bolt is commonly used for attaching brackets and supports where space constraints do not allow for standard hex bolts with separate washers.

The Bracket is a simple yet essential L-shaped or flat mounting piece that connects various subassemblies to the main structure. It provides a reliable interface for bolted connections.

Stamped or laser-cut from high-strength sheet steel, the Bracket is lightweight yet strong enough to support auxiliary components and sensors.

Its straightforward design allows for quick replacement and customisation, making it a versatile component in the Engine bracket assemby system.

The Spring washer is a helical split ring that exerts a continuous axial force on the bolt joint, preventing loosening due to vibration. It acts as a locking device with a simple, reliable mechanism.

Made from spring steel with a corrosion-resistant finish, the Spring washer maintains its elasticity over many cycles of loading and unloading.

Its compact size and low cost make it an ideal choice for securing bolts in the Engine bracket assemby without adding significant weight or bulk.

The Engine mounting is the primary load-bearing elastomeric component that isolates engine vibrations from the chassis. It combines a steel core with a rubber or polyurethane cushion.

This mounting absorbs both high-frequency vibrations and low-frequency shocks, contributing to a smoother ride and reduced noise inside the cabin.

The Engine mounting is designed to withstand high temperatures and oil exposure, ensuring long service life even under severe operating conditions.

The Flat washer is a thin, annular plate placed under the bolt head or nut to distribute clamping load and protect the surface from damage. It also helps to compensate for clearance variations.

Made from hardened steel with a smooth finish, the Flat washer reduces friction during tightening, enabling more accurate torque readings and consistent preload.

This component is widely used throughout the Engine bracket assemby to ensure uniform load distribution and prolong the life of both fasteners and mating surfaces.

The Motor rear support left bracket assembly is the mirror-image counterpart of the right side bracket, securing the rear left side of the engine to the frame. It balances the load across both rails.

Manufactured using the same high-quality steel and welding techniques, this bracket offers identical strength and durability characteristics as its right-side partner.

Together with the right assembly, it ensures that the engine remains stable during acceleration, braking, and cornering, minimising unwanted movement and reducing wear on drive components.

The 2 type full metal Hex locking nut is a high-performance fastener that provides a prevailing torque locking feature without any non-metallic inserts. Its all-metal construction offers excellent heat resistance.

This nut achieves its locking action through controlled elastic deformation of the threads, which creates a consistent frictional force that resists loosening under extreme vibration.

It is reusable multiple times without significant loss of locking performance, making it a cost-effective choice for maintenance and repair operations on the Engine bracket assemby.

The Sleeve is a tubular spacer used to maintain proper stand-off distance between components and to protect bolt threads from excessive bending or shear loads. It also acts as a guide for alignment.

Precision-machined from steel tubing, the Sleeve is chamfered at both ends to facilitate assembly and reduce stress concentrations at the interface.

This component is critical for maintaining the correct spatial relationship between the Engine bracket assemby and the chassis, ensuring that all fasteners are properly engaged.
