High efficiency gear transmission |
摘要 |
A mechanical gear transmission between an engine and a load includes shiftable speed change gearing. Brakes or clutches are provided for shift synchronization when changing to different speeds. Positioned between the engine and the gearing is a main synchronization element such as a clutch. The primary segment of the main synchronization element is driven by the engine output shaft while the secondary segment drives the input shaft of the speed change gearing. During a gear shift under load, the main synchronization element is maintained in a slip mode for a longer duration than the gearing synchronization element and provides the major portion of the total synchronization work. In alternate embodiments, the main synchronization element is combined with a planetary gearing for speed reduction on a pair of planetary gearings for reversing direction. A further embodiment incorporates a microprocessor controller and sensors for monitoring various engine and transmission functions. The microprocessor controller actuates the main and the gearing synchronization elements and may control the engine during a gear change.
