Title:
FULLY-MECHANICAL SELF-ADAPTIVE AUTOMATIC TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2021/110155
Kind Code:
A1
Abstract:
A fully-mechanical self-adaptive automatic transmission, comprising a power input mechanism, a high-speed gear transmission mechanism, a low-speed gear transmission mechanism, and a main shaft (1) for outputting power. The high-speed gear transmission mechanism comprises a friction clutch (2) and an elastic element group (3) for applying a preload force to the friction clutch (2); the power input mechanism transfers power to the friction clutch (2) by means of a first overrunning clutch (4), the friction clutch (2) is sleeved on the main shaft (1) by means of an inner plate spiral raceway sleeve (5), and a spiral transmission pair is formed between the inner plate spiral raceway sleeve (5) and the main shaft (1) to enable the inner plate spiral raceway sleeve (5) to axially slide along the main shaft (1); the low-speed gear transmission mechanism comprises a second overrunning clutch (6) and an auxiliary shaft transmission assembly for speed reduction transmission between the power input mechanism and the second overrunning clutch (6), the second overrunning clutch (6) is sleeved on the main shaft (1) by means of an inner core wheel cam sleeve (7), and the inner core wheel cam sleeve (7) can transfer power to the main shaft (1) by means of the inner plate spiral raceway sleeve (5). The apparatus can automatically perform gear shifting and speed changing adaptively with traveling resistance changes under the condition that driving force is not cut off, the gear shifting is smooth, the efficient running interval of a motor is greatly increased, the apparatus can be used in mountainous areas, hills and heavy load conditions, so that the load change of the motor or an engine is gentle, and the whole vehicle runs stably and is high in safety.
