Abstract
The present invention relates to a speed variable system, and in the first input rotating direction, it is capable of controlling the output shaft to output in normal and reverse rotating directions, and the input shaft is in different speed ratios to the output shaft with respect to the normal and reverse rotation directions.
Claims11
A three-end shaft type differential gear set with a controllable rotating direction, comprising:
- a first input/output shaft (S101) and a second input/output shaft (S102);
- a controllable brake device (BK101);
- and
- a controllable clutch device (CL101) between the second input/output shaft (S102) and the first input/output shaft (S101) for controllably coupling the second input/output shaft (S102) to the first input/output shaft (S101),
- wherein the first input/output shaft (S101) has a sleeve shape and coaxially surrounds a part of the second input/output shaft (S102), and
- wherein the controllable brake device (BK101) and the controllable clutch device (CL101) are controllable to cause the following relationships between the second input/output shaft (S102) and the first input/output shaft (S101):
- the rotating direction of the first input/output shaft (S101) is the same as or different from the rotating the direction of the second input/output shaft (S102), the second input/output shaft (S102) and the first input/output shaft (S101) to be in a released state without mutual transmission, and the second input/output shaft (S102) and the first input/output shaft (S101) to be locked in a non-rotating state.
