飞思卡尔杯B型车模机械部件的改进探讨

An Exploration of the Improvement of the Mechanical Parts of the B-type Freescale Cup Cars

针对B型车模存在的底盘太高、减震器过于灵敏、舵机响应慢、测速码盘安装不便等问题,经过系列改进,通过压缩弹簧以降低底盘重心和减轻减震太软带来的震荡;选择合理的定位参数,提高了小车行走的稳定性及控制的灵敏度;舵机、测速码盘合理安装,提高舵机响应速度,为智能车快速、平稳前进、转弯以及制动控制提供更好的基础.

There exist the problems of too high chassis,too sensitive shock absorbers,slow response of the steering,and the inconvenience of the installation of the speedometer in the B-type Freescale cars.A series of improvements can be made： shock can be reduced by lowering the gravity center of the chassis to reduce the vibration caused by too soft shock-absorbers;improving the stability and sensitivity of the control of the car in motion;and improving the steering response through reasonable installation of the steering unit and speedometer.
