Description

Technical Field

[0001] The utility model relates to the field of comprehensive transmission device performance test equipment, in particular to a no-load test detection system for a comprehensive transmission device. Background Art

[0002] The integrated transmission is a crucial component of the high-speed tracked vehicle transmission system. It integrates a torque converter, a planetary powershift transmission, a hydraulic continuously variable steering system, and an electro-hydraulic automatic control system, achieving both power shifting and continuously variable steering. Its performance significantly impacts the overall vehicle performance and the life of the transmission system. Due to the complex structure and numerous interfaces with various onboard systems, the integrated transmission's assembly and commissioning are complex and technically challenging. Furthermore, the limited space within the vehicle's chassis power compartment makes it difficult to inspect and troubleshoot malfunctions within the internally installed assembly.

The transmission, engine, data acquisition system, and its auxiliary systems undergo assembly quality inspections, basic performance parameter testing, and joint commissioning. This assesses the operating condition of the integrated transmission and the accuracy and reliability of related data transmission to ensure the quality of its installation and commissioning.
