AI Technical Summary

Technical Problem

The TE17 transmission experiences low lubricant temperature during startup in cold weather, resulting in poor lubrication, a long warm-up period, reduced transmission efficiency, and increased wear on transmission components.

Method used

Design a TE17 gearbox assembly that adopts a lubrication system that automatically switches the oil circuit based on the lubricating oil temperature. During cold start, the lubricating oil bypasses the oil cooler and circulates directly. The lubricating oil temperature is adaptively controlled through drive components and locking components, and the direct flow channel and cooling flow channel are automatically switched.

Benefits of technology

Shorten warm-up time, improve gearbox efficiency, reduce wear on transmission components, enhance lubrication and cooling effects, and improve system adaptability and reliability.
