Barrel type straight spindle: spindle and spindle motor to reduce the transmission link error and vibration, the use of integrated direct design, and the use of high precision ABECT.

In this paper the performance characteristics of the moter vehicle during braking are studied, the exciting force and moments applied to motor vehicle braking on a straight way are discussed.

Therefore, this research would provide a instructive reference straight for the structure design of thrust-vectoring motor and jet et vane.
