Emergency brake system for motor vehicle, has planet gear carrier that is intensely decelerated so that rotation speed of propeller shaft halves is lowered and rotation direction of driving wheels is completely reversed

摘要

The system has an intermediate planetary gear connecting two propeller shaft halves (1a, 1b) of a motor vehicle, where the planetary gear rotates along with the propeller shaft halves without any specific function during a normal driving condition. A bypass gear (2) is released and a freely rotating planet gear carrier (3) is intensely decelerated when an emergency braking is triggered, so that rotation speed of the propeller shaft halves is lowered and the rotation direction of actual driving wheels of the vehicle is completely reversed.
