Transmission mechanism for driving four wheels

A transmission mechanism for driving four wheels of an automotive vehicle comprising

• a driving power input shaft connected with a motor of the automotive vehicle;
• a first driving power input gear rotably mounted on the driving power input shaft;
• a first slidable engaging member slidably mounted on the driving power input shaft;
• a second driving power input gear rotably mounted on the driving power input shaft;
• a third slidable engaging member slidably mounted on the driving power input shaft;
• a first differential mechanism including a first half shaft sleeve, a second half shaft sleeve, and a first ring gear engaged to the first driving power input gear;
• a second differential mechanism including a third half shaft sleeve, a fourth half shaft sleeve, and a second ring gear engaged to the second driving power input gear;
• a first core shaft passing through the first differential mechanism;
• a second core shaft passing through the second differential mechanism;
• a second slidable engaging member for coaxially connecting the first core shaft with the second core shaft;
• a first gear rotably mounted on the second half shaft sleeve;
• a second gear rotably mounted the fourth half shaft sleeve;
• a first gear shaft engaged to the first gear for driving a wheel decelerator of the automotive vehicle;
• a second gear shaft engaged to the second gear for driving a wheel decelerator of the automotive vehicle;
• a first connecting member connected with the first core shaft for driving a wheel decelerator of the automotive vehicle;
• and
• a second connecting member connected with the second core shaft for driving a wheel decelerator of the automotive vehicle, wherein the first slidable engaging member and the third slidable engaging member can be regulated to engage the first driving power input gear and the second driving power input gear respectively, so as to drive different wheels of the automotive vehicle.
