The part is a critical pneumatic actuation device engineered specifically for HOWO 4X2 tractor trucks. This complete brake chamber assembly comprises four essential components: the 27/27 Brake chamber (L=70), the Cotter pin, the Axis pin, and the Flat washer. Each part is precision-manufactured to deliver reliable braking performance under demanding operational conditions. As a core safety solution, this assembly ensures that your vehicle’s braking system functions with exceptional accuracy and consistency. When you choose authentic howo Parts, you invest in durability, precision, and long-term operational safety for your fleet. The part assembly is designed to meet the rigorous standards of modern heavy-duty transportation.
The 27/27 Brake chamber (L=70) is the primary actuation unit within The part assembly. This clamp-on-diaphragm type chamber converts compressed air pressure into mechanical force to engage the braking mechanism[reference:0]. With a type 27/27 configuration and an L=70 stroke length, this chamber delivers optimal braking force for HOWO 4X2 tractor applications[reference:1]. The chamber consists of an air inlet, cover, diaphragm, support plate, return spring, housing, push rod, connecting fork, clamp, and bolts[reference:2]. Its robust construction ensures consistent performance across thousands of braking cycles, providing reliable deceleration and stopping power for heavy-duty commercial vehicles[reference:3].
The Cotter pin is a vital securing component within The part assembly. This small but essential fastener locks the axis pin in place, preventing unintended disconnection during vehicle operation. Manufactured from high-strength steel, the cotter pin provides reliable mechanical locking that withstands vibration and shock loads common in heavy-duty trucking environments. Its simple yet effective design ensures that The part’s moving parts remain securely connected, contributing to the overall reliability and safety of the braking system.
The Axis pin serves as the pivotal connection point within The part assembly. This precision-machined pin provides the mounting interface between The part and the slack adjuster or brake linkage. Manufactured from durable steel with wear-resistant surface treatment, the axis pin maintains proper alignment and smooth operation of the braking mechanism. Its precise dimensions ensure correct geometry between The part pushrod and the slack adjuster, enabling efficient force transmission and consistent brake application.
The Flat washer is a critical load-distributing component within The part assembly. Positioned beneath the fastener head, this washer spreads the clamping load evenly across the mounting surface, preventing damage to The part housing and ensuring secure attachment. Manufactured from corrosion-resistant steel, the flat washer maintains its integrity even in harsh environmental conditions. Its proper installation is essential for maintaining the correct torque specifications and preventing loosening of The part mounting hardware over time.
