Our GLL timing chain's core advantage starts with material selection. Our products are made of high-strength alloy steel. After special heat treatment, the wear resistance and tensile strength are improved by more than 30% compared with ordinary alloy steel. This material property enables the chain to maintain stable deformation under high-speed (driving sprocket speed can reach more than 8000r/min) and high-load conditions, effectively extending the service life.
In terms of chain type, our GLL mainly promotes the Silent Chain design. Compared with traditional roller chains, the Silent Chain reduces transmission noise by about 15 decibels through the meshing transmission of chain links and sprockets, while increasing transmission accuracy by 20%. This feature is particularly critical in multi-cylinder engines such as V6 and V8, whose multi-axis transmission systems have extremely high requirements for timing accuracy. The micron-level transmission error control capability of the Silent Chain can ensure the precise synchronization of valve opening and closing time and piston movement, avoiding engine knock or power loss.
The design life of our GLL timing chain is consistent with that of the entire engine.
Durability: After 25,000 hours of continuous operation, the wear of our GLL chain is still below the allowable threshold of 1%, far exceeding the industry average.
Maintenance cost: Compared with the timing belt that needs to be replaced every 60,000 kilometers, the lifetime maintenance-free feature of our GLL chain can save users about 5,000 yuan in long-term use costs.
Power response: The low inertia design of the toothed chain shortens the engine speed climbing response time by 12%. In actual tests of models such as the Sagitar GLI, the power connection smoothness when shifting at 6000rpm is improved by 18%.
Our GLL not only provides single chain products, but also focuses on the integrated innovation of timing systems:
Dynamic tension compensation technology: Through the coordinated design of hydraulic tensioners and chain guides, it automatically compensates for tension changes caused by thermal expansion and wear, ensuring that the transmission system is always in the best working range.
NVH optimization: Coating the surface of the chain guide with a low friction coefficient coating, combined with the sound insulation design of the engine compartment, the timing system noise is reduced to below 38 decibels, reaching the quietness standard of luxury cars.
Lightweight design: Using hollow pins and high-strength plastic guides, the weight of a single chain is reduced by 15%, helping the engine achieve a 5% improvement in fuel consumption.
