Power steering oil pump, oil pipe, power steering oil reservoir for needing etc., number of parts is few, and arrangement is convenient, light-weight.Especially automobile
Power steering is variation in driving process, because the lateral resistance of tire is small, and steering wheel is unstable when running at high speed, is difficult
The feeling for capturing road surface also be easy to cause and turns to excessively sensitive and keep automobile not easy to control, so suitably to lower in high speed
Power, but this variation must smoothly excessively, and such case only uses electric powered steering just to can solve.Therefore electric power steering
System can save energy reduction oil consumption under various driving conditions, improve the runnability of automobile, decreases oil leaking pollution, changes
It has been apt to environment.
