双摇臂悬架

<font color="red"><font size="6">双摇臂悬架&nbsp;</font></font><br><br>双摇臂悬架是独立悬架的
一种,也叫双叉骨、双愿骨(double&nbsp;wish&nbsp;bone)悬架,为什么有双愿骨这个名字呢?西方过圣诞节的时候人们喜欢吃火鸡,在吃的时候要对这火
鸡上的一根骨头许个愿,这条有点像A字的骨头就叫愿骨wish&nbsp;bone,双摇臂悬架上的A字型摇臂与这根愿骨比较相像,所以又叫双愿骨。<br><br>双
差臂悬挂拥有上下两个不等长的摇臂,双横臂的臂有做成A字形或V字形。V形臂的上下2个V形摆臂以一定的距离,分别安装在车轮上,另一端安装在车架上。横
向力由两个摇臂同时吸收,支柱只承载车身重量,因此横向刚度大。由于上下摇臂不等长(上长下短),让车轮在上下运动时能自动改变外倾角并且减小轮距变化,
上臂比下臂运动弧度小,减小轮胎磨损。并且也能自适应路面,轮胎接地面积大,贴地性好。但是由于多了一个上摇臂,所以需要站用较大的空间,因此小型车的前
桥一般布置不下此种悬挂。双摇臂悬挂设计是大型轿车、越野车和城市休闲SUV前悬架惯用的设计手法。而这种设计相对麦弗逊式设计稳定性、适应性要更出色,
增加横向承受力的刚性,使用寿命得以大大提升。同时在使用双叉臂结构设计后使得减震支柱不承受横向力,提高汽车行驶平顺性和方向稳定性。但任何结构设计的
优势都不是绝对的,相对麦弗逊它的设计结构更加复杂,相应速度、灵敏性相对较低,乘坐舒适性相对打了折扣。<br><br><font color="navy">优点:悬架刚度大,承受冲击力强,能保持轮胎紧贴路面。</font><br><font color="red">缺点:占用空间较大,悬架精度没有多连杆的高。&nbsp;</font><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700675030.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700675030.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;1&nbsp;幅&nbsp;Alfa_Romeo_159_2.4_JTDM_2005_双摇臂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700697604.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700697604.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;2&nbsp;幅&nbsp;Acura_RL_SH-AWD_Chinese_Version_2006_前摇臂悬挂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700719660.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700719660.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;3&nbsp;幅&nbsp;Lincoln_MKZ_AWD_2007_前双摇臂悬架.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700743012.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700743012.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;4&nbsp;幅&nbsp;Jaguar_S-Type_R_2003_前双摇臂悬挂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700763683.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700763683.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;5&nbsp;幅&nbsp;Jaguar_XJR_2004_前双摇臂悬挂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700797681.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700797681.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;6&nbsp;幅&nbsp;Maserati_Quattroporte_2004_前双摇臂悬架.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700820005.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700820005.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;7&nbsp;幅&nbsp;Mercedes-Benz_ML500_2006_前双摇臂悬挂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700842892.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700842892.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;8&nbsp;幅&nbsp;Mercedes-Benz_GL450_4MATIC_2007_前双摇臂悬挂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700869449.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700869449.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;9&nbsp;幅&nbsp;Nissan_Fuga_350GT_2004_双摇臂悬挂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700894967.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700894967.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;10&nbsp;幅&nbsp;Mercedes-Benz_R500_2006_前双摇臂悬挂.jpg&nbsp;<br><br><br><a href="http://bbs.pcauto.com.cn/viewpic.jsp?imgUrl=http%3A%2F%2Fimg.pconline.com.cn%2Fimages%2Fbbs4%2F20076%2F13%2F1181700920172.jpg" target="_blank"><img src="http://img.pconline.com.cn/images/bbs4/20076/13/1181700920172.jpg" alt="按此在新窗口浏览图片" onload="javascript:if(this.width>screen.width-500)this.width=screen.width-500;" border="0" width="524"></a> <br>第&nbsp;11&nbsp;幅&nbsp;Volkswagen_Phaeton_2002_前双摇臂悬架.jp
