 YILAITE pneumatic lock valve assembly WG2203250010


——Heavy truck gearbox safety locking core component


Product overview


ELITE air-controlled locking valve assembly WG2203250010 It is the core component of the air system specially designed for heavy-duty trucks equipped with HW series transmissions such as Sinotruk Howo T7H, Shandeka C7H/C9H, and Haohan J7G/N7G. By accurately controlling the air circuit signal, the transmission gear can be safely locked and unlocked, effectively preventing transmission damage caused by misoperation and ensuring the operational reliability of the vehicle under complex working conditions.


[P_STA RT] Brand and production: YILAITE

Applicable models: Sinotruk Howo T7H, Shandeka C7H/C9H, Haohan J7G/N7G and other HW series transformers Speed ​​box heavy truck


Core function analysis


[P1. Gear Interlock Protection: The transmission auxiliary gearbox piston movement is controlled via air circuit signals to achieve mechanical interlock between high and low gear ranges. When the vehicle is in motion, the current gear is automatically locked to prevent unexpected gear shifts caused by accidental clutch or gear shift lever operation. 2. Safety Unlocking Mechanism: Equipped with a sliding column extension protection device, when the cylinder seals wear, the air pressure can be compensated by adjusting the valve core to maintain gear lock stability. The unlocking process requires simultaneous fulfillment of both air pressure signal and mechanical linkage conditions to avoid false locking due to a single signal error. 3. The optimized air circuit system

employs an end-face sealing structure, significantly improving the reliability of air circuit connections and reducing air pressure leakage or cross-contamination issues.

A built-in fault protection valve automatically cuts off the air pressure supply when the air circuit system malfunctions, preventing the transmission from entering a dangerous state.


Technical advantages and adaptability


1. Original Factory Compatibility

Strictly adheres to the air circuit design standards of HW series transmissions for models such as Sinotruk Howo and Sinotruk Shandeka, ensuring seamless replacement of original parts.

The interface and pipeline layout are completely matched to the original vehicle, requiring no additional modifications after installation.


2. High-Efficiency Response

By optimizing the air circuit channel design, the air pressure transmission path is shortened, improving the immediacy of lock/unlock operations.

Response time ≤ 0.2 seconds, meeting the safety requirements of frequent gear changes in heavy truck scenarios.


3. Enhanced Durability

The valve body is made of high-strength alloy material, suitable for the long-term high-load operation environment of heavy trucks.

After 500,000 cycle tests, its wear resistance is significantly better than that of ordinary pneumatic components.


Application Scenarios and Value


1. Heavy-duty Transportation

In mountainous areas or complex road conditions, ensuring...The precision of gear shifting prevents power interruption due to misoperation.

The locking function prevents the vehicle from rolling back due to incorrect gear selection when starting on an incline.


2. Urban Logistics

In frequent start-stop scenarios, smooth gear shifting reduces mechanical wear and maintenance costs.

The unlocking mechanism prevents gearbox damage due to driver misoperation and extends its service life.


3." Retrofit and Upgrade:

Provides standardized interfaces for performance optimization, compatible with mainstream heavy-duty truck pneumatic system modification needs.

Can be paired with other Elet pneumatic components (such as dual H-valve assemblies) to achieve system-level upgrades.


Brand and Service Support:

Production Guarantee: Zhejiang Chuangtuo Automotive Parts Co., Ltd. relies on automated production lines to ensure batch consistency and quality stability of products.

After-sales System: Provides technical consultation and fault diagnosis services to assist users in quickly locating pneumatic system abnormalities.
