后轮

Responding to differences in speed between the right and left rear wheel, the Variable M Differential Lock also offers ideal support further enhancing the positive features and characteristics of rear-wheel drive.

响应之间的权利和左后轮轮速差异，可变M差速锁也提供了理想的支持，进一步加强积极的特点和后轮驱动的特点。

This paper presents a research of the dynamic characteristics testing method of the rear wheel of a typical car and new experimental project and testing method based on the four-post vehicle road simulation system.

以某典型中级轿车后轮为例，对轿车后轮定位参数动态特性试验测试方法进行了研究。

This four-wheeler change direction system to fasten exploitation controller to accept a car to soon spread feeling machine and steer device to turn the signal that the Cape spread a feeling machine to come to compute empress a round need it turn Cape, subsequently make the liquid press system push empress rotate to, but after this four-wheeler change direction vehicle rotate Cape most can only attain one degree.

此四轮转向系统系利用控制器接受车速传感器及方向盘转角传感器之讯号来计算出后轮所需之转角，继而使液压系统推动后轮转向，而此四轮转向车辆之后轮转角最多只可达到1度。

It was driven by a belt that ran from the motor to a sheave on the rear wheel that was almost as large as the rear wheel itself.

这是驱动的带跑的汽车到带轮的后轮是几乎一样大后轮本身。

It has a unique design: its paired back wheels splay outward when the bike is at rest, and are drawn inward when the bike is in motion, to work more like a single wheel.

它的设计独一无二：当车静止时，它的两只后轮是向外张开的；当车前进时，后轮则向内收缩成近乎一个轮子。

The dynamic characteristics of the toe-in and camber of the rear wheel were measured on the vibration test table. The influences of different input manners were investigated such as the swept input and the stochastic input, the single input and the dual input. And an analysis was made of the testing results and the testing error.

设计制定了基于电－液伺服四通道车辆道路模拟试验台的后轮定位参数测量试验方案，在振动台架上测定该车后轮前束角和外倾角的动态变化特性，研究了扫频信号和随机信号加载和单双侧加载等不同的加载方式对测试结果的影响，并对试验结果进行了误差分析。

Besides, the rear wheel of the walker is equipped with the electro- magnetic brake which can be triggered by the controller and therefore lock the rear wheel when the speed of the walker is too high.

并在助行器的后轮上装有电磁煞车，当助行器的速度过快时，控制器送出讯号启动电磁煞车将后轮锁住，以避免使用者发生危险。

The obstacle (the altitude of 900 mm) process for both sides of a planetary gear train was analyzed in ADAMAS. It is proved that the physical dimension of the planetary gear train, bodywork center position and attachment coefficient are the key effect factors. The driven moment, velocity and normal pressure sharply increased as each wheel surmounting obstacles, but they were moderate after the front wheel came over the obstacles. Another weaker pulse occurred when the rear wheel began climbing, and then the parameters reached a plateau.

行星轮系的结构尺寸、车体质心位置及附着系数对越障高度影响较大；各轮系越障时出现驱动力矩、速度和正压力急增的现象，前轮系的前轮越上障碍后，各参数值趋于平稳，后轮越障时又出现瞬时脉动，但脉动较小，后轮系也有相同的变化趋势，各轮的阻力矩和输出功率与正压力变化趋势相同。

Followingly,among the existing brake control strategy, most don't consider the problem of battery anti-overcharging.So,a practical electric vehicle regenerative braking strategy that considering battery state of charge is proposed, and braking force distribution controller and regulator are designed respectively according to vehicle safety requirements and battery SOC constraint.

接着针对现有制动控制策略中，未考虑抑制电池过充的问题，提出了一种实用的考虑电池SOC约束的再生制动力分配策略，根据车辆前后轮制动力安全要求和电池SOC约束，分别设计了前后轮制动力分配控制器和制动力调节器。

Lock it by dropping the seatpost, then swing the front wheel under and round, and tuck it in next to the rear wheel, with the derailleur nestled between the front wheel spokes.

折叠前须将链条变到后飞轮最小齿，接著将后轮往前荡向主管下方，下滑座杆将之卡住；再来把前轮向车身收折至后轮旁，此时后变速器会恰好介於前后轮钢丝间；最后将立管放下折向另一边。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
