《电动汽车同步器设计与计算案例综述3300字》
电动汽车同步器设计与计算案例综述1.1.同步器选型本设计中,同步器的结构为锁环式,又称为滑块式。
这种同步器的结构主要包括齿毂、滑块、定位销、弹簧、结合齿圈。
考虑到其组合与自身功能,同步器的各个零件有着功能尺寸与配合安装的尺寸。
同步器的每个零件都需要自己的功能尺寸,同时在安装过程中零件之间也要有匹配的尺寸;联接夹具的外径,花键孔的大直径,花键参数和宽度;还有相应的零件尺寸参数同步环,例如同步带孔大端的直径,半锥角,圆锥形表面的长度,摩擦系数,锁紧角度,组合齿的分度环半径,齿端的倒角,边线角度,同步环槽的宽度,刮油器和排油槽的参数;箔的宽度;合适的尺寸包括滑块中的圆形照明同步器环的凹槽,安全行程,接近尺寸,滑块的末端自由度等。
在设计之初,同步器的参数基于为了获得较短的组合时间,良好的驾驶舒适性和较长的使用寿命,已开发了同步器的寿命和组合性能。
1.1是锁紧环同步器的剖视图:图1.11、同步器接合套2、同步环3、同步环4、花键毂5、同步器弹簧6-7、同步器滑块块同步器附件被弹簧固定在一个固定的齿轮插座上(每组3组)。
同步推进单元的头部位于一个环形齿轮槽中。
当传动装置向轴向移动时,首先必须克服同步压力单元的阻力,然后由推进器推进器施加的力必须通过弹簧、传动轴同步和同步同步来达到柔性换向,达到明显的效果。
它可以避免被踢到齿轮表面的声音。
下图为同步器的整个换档过程应为3的整倍数。
m=2,根据GB3478.1−83:1.2.锥孔直径及倾斜角,锥面平均半径和工作长度的确定同步环锥形孔的DC大端直径是根据齿的分度圆直径D来定义的。
对于轻型车来说,它们之间的差值是12-15毫米。
如果洞太小,同步能力太小,洞太大,环壁太厚,强度不够。
锁环预选中等差13.5,Dc=41.5.同步环锥面半锥角α与换挡时候的同步力矩成反比。
但α太小可能会发生自锁现象。
根据以下公式计算α:f tan >α (7-1)将f 代入得α>6.3°,考虑到f 在使用中会有所降低,这里选择α=7°作为同步环的内锥角。

同时也可以使发动机在最有利的工况范围内工作。
为保证变速器具有良好的工作性能,对变速器提出以下基本要求:1. 应有合适的变速档位数和传动比,保证汽车具有良好的动力性和经济性指标。
2. 较高的传动效率。

由此可见,用常压式同步器换档与用接合套换档比较,在工作过程上的区别,主要在于前者的摩擦作用能使需 接合的两花键齿圈迅速地达到并保持同步。
惯性式同步器与常压式同步器一样,都是依靠摩擦作用实现同步。但它可以从结构上保证接合套与待接合的 花键齿圈在达到同步之前不可能接触,以避免齿间冲击和发生噪声。
惯性式同步器广泛应用于轿车和轻、中型货车的变速器中。常用的结构形式有锁环式惯性同步器和锁销式惯 性同步器两种。
只要接合套与待啮合齿轮之间存在转速差,弹簧片的支承力就阻止同步环直径缩小,因而也就阻止了接合套 移动。在二者的转速差为零(同步)时,弹簧片卸除载荷,即以右弹簧片的上端为支点,弹簧片伸张,其下端顶 住支承块凸起右侧,推动接合齿圈连同低档齿轮一道顺时针方向转动一个角度,使弹簧片松弛,于是阻止同步环 直径缩小的支承力消失。此时,在不大的换档力作用下,接合套便可压缩同步环,与右侧的接合齿圈接合,而同 步环处于接合套的屋顶状凹槽里,被可靠地定位。因此,在挂档位置,毋需采用一般变速器所必须设置的自锁装 置。
常压式同步器在齿轮2与4接合齿圈相对的一侧均有一个外锥面。相应地在花键毂两侧加工出内锥面。在花键 毂的径向孔内,装有定位销6,它借弹簧的压力嵌入在接合套3内切出的环形凹槽中。图1上部的三个图为在挂直 接档的过程中同步器的工作示意图。图1a表示接合套在空档位置。挂直接档时,向左拨动接合套,则通过定位销 带动花键毂1一同左移。当花键毂的内锥面与齿轮2的外锥面接触时,花键毂即不能再继续左移。由于接合套与花 键毂之间有弹簧顶住的定位销6,若驾驶员作用在接合套上的力不大,则定位销便阻止接合套在花键毂停止不动的 情况下继续向左移动。此时位置如图1b所示。两锥匦在驾驶员通过操纵机构加于接合套和花键毂上的力的作用下 互相压紧。齿轮2与花键毂存在转速差,因而两锥面一经接触,便产生摩擦作用。这种摩擦作用促使第一轴齿轮的 转速迅速降低到与花键毂的转速(亦即接合套的转速)相等,因而二者花键齿的圆周速度相等(同步)。此时驾 驶员继续增大加于接合套上的推力,使接合套克服弹簧力压下定位销6而相对花键毂继续左移,其内花键齿圈便与 齿轮 &的接合齿圈接合,即挂入直接档,如图1c所示。

同步器有常压式,惯性式和自行增力式等种类。
这里仅介绍目前广泛采用的惯性式同步器。
惯性式同步器是依靠摩擦作用实现同步的,在其上面设有专设机构保证接合套与待接合的花键齿圈在达到同步之前不可能接触,从而避免了齿间冲击。
惯性同步器按结构又分为锁环式和锁销式两种。
其工作原理可以北京BJ212型汽车三档变速器中的二、三档同步器为例说明。
花键毂7与第二轴用花键连接,并用垫片和卡环作轴向定位。
在花键毂两端与齿轮1和4之间,各有一个青铜制成的锁环(也称同步环)9和5。
锁环上有短花键齿圈,花键齿的断面轮廓尺寸与齿轮 1,4及花键毂 7上的外花键齿均相同。
在两个锁环上,花键齿对着接合套8的一端都有倒角(称锁止角),且与接合套齿端的倒角相同。
锁环具有与齿轮1和4上的摩擦面锥度相同的内锥面,内锥面上制出细牙的螺旋槽,以便两锥面接触后破坏油膜,增加锥面间的摩擦。
三个滑块2分别嵌合在花键毂的三个轴向槽11内,并可沿槽轴向滑动。
在两个弹簧圈6的作用下,滑块压向接合套,使滑块中部的凸起部分正好嵌在接合套中部的凹槽10中,起到空档定位作用。
滑块2的两端伸入锁环9和5的三个缺口12中。
只有当滑块位于缺口12的中央时,接合套与锁环的齿方可能接合。

同步器设计
第五节同步器设计同步器有常压式、惯性式和惯性增力式三种。
常压式同步器结构虽然简单,但有不能保证啮合件在同步状态下(即角速度相等)换挡的缺点,现已不用。
得到广泛应用的是惯性式同步器。
一、惯性式同步器惯性式同步器能做到换挡时两换挡元件之间的角速度达到完全相等之前,不允许换挡,因而能完善地完成同步器的功能和实现对同步器的基本要求。
按结构分,惯性式同步器有锁销式、滑块式、锁环式、多片式和多锥式几种。
虽然它们的结构不同,但都有摩擦元件、锁止元件和弹性元件。
图3—17a所示锁销式同步器的摩擦件是同步环2和齿轮3上的凸肩部分,分别在它们的内圈和外圈设计有相互接触的锥形摩擦面。
锁止元件位于滑动齿套1的圆盘部分孔中做出的锥形肩角和装在上述孔中、在中部位置处有相同角度的斜面锁销4。
锁销与同步环2刚性连接。
弹性元件是位于滑动齿套1圆盘部分径向孔中的弹簧7。
在空挡位置,钢球5在弹簧压力作用下处在销6的凹槽中,使之保持滑动齿套与同步环之间没有相对移动。
滑动齿套与同步环之间为弹性连接。
图3—17b所示锁环式同步器摩擦元件,是通过滑动齿套8及锁环9上的锥面来实现的。
作为锁止元件是锁环9的内齿和做在齿轮10上的接合齿端部。
齿轮10和锁环9之间是弹性连接。
图3—17 惯性式同步器结构方菜a)锁销式 b)锁环式1、8--滑动齿套 2--同步环 3、10--齿轮 4--锁销5--钢球 6--销 7--弹簧 9--锁环在惯性式同步器中,弹性元件的重要性仅次于摩擦元件和锁止元件,它用来使有关部分保持在中立位置的同时,又不妨碍锁止、解除锁止和完成换挡的进行。
锁销式同步器的优点是零件数量少,摩擦锥面平均半径较大,使转矩容量增加。
这种同步器轴向尺寸长是它的缺点。
锁销式同步器多用于中、重型货车的变速器中。
滑块式同步器本质上是锁环式同步器,它工作可靠、零件耐用;但因结构布置上的限制,转矩容量不大,而且由于锁止面在同步锥环的接合齿上,会因齿端磨损而失效,因而主要用于轿车和轻型货车变速器中。

毕业设计论文_汽车同步器的设计说明书
第一章绪论1.1 选题背景1.1.1 汽车同步器的应用与发展趋势近几年来我国汽车行业发展迅速,产量连年突破新高。
汽车工业已成为国民经济的第四大支柱行业,同时我国仅次于美、日、德的汽车第四大生产国。
随着汽车产业的发展,对机械换档装置中的重要部件——同步器的要求也越来越高。
但是,目前国内对同步器的研究很少,其生产还处于照抄照搬的模仿阶段,而在普通齿轮变速器中采用同步器,可以保证换档时齿轮啮合不受冲击,消除噪声,延长齿轮寿命,使换档动作方便迅速,有利于提高汽车的动力性和燃油经济性,由此可见同步器的重要。
图1.1 汽车同步器1.1.2我国同步器发展的现状由于变速器输入轴与输出轴以各自的速度旋转,变换档位时啮合存在一个"同步"问题。
两个旋转速度不一样齿轮强行啮合必然会发生冲击碰撞,损坏齿轮。
因此,旧式变速器的换档要采用"两脚离合"的方式,升档在空档位置停留片刻,减档要在空档位置加油门,以减少齿轮的转速差。
但这个操作比较复杂,难以掌握精确。
因此设计师创造出"同步器",通过同步器使将要啮合的齿轮达到一致的转速而顺利啮合。
1.1.3 锁环式同步器的特点、组成与分类同步器有常压式,惯性式和自行增力式等种类。
惯性式同步器是依靠摩擦作用实现同步的,在其上面设有专设机构保证接合套与待接合的花键齿圈在达到同步之前不可能接触,从而避免了齿间冲击。
惯性同步器按结构又分为锁环式和锁销式两种。
目前全部同步式变速器上采用的是惯性同步器,它主要由接合套、卡环(锁环)等组成,它的特点是依靠摩擦作用实现同步。
接合套、锁环和待接合齿轮的齿圈上均有倒角(锁止角),锁环的内锥面与待接合齿轮齿圈外锥面接触产生摩擦。
锁止角与锥面在设计时已作了适当选择,锥面摩擦使得待啮合的接合套与接合齿圈迅速同步,同时又会产生一种锁止作用,防止齿轮在同步前进行啮合。
当同步锁环内锥面与待接合齿轮齿圈外锥面接触后,在摩擦力矩的作用下齿轮转速迅速降低(或升高)到与锁环转速相等,两者同步旋转,齿轮相对于锁环的转速为零,因而惯性力矩也同时消失,这时在作用力的推动下,接合套不受阻碍地与锁环、接合齿圈接合,并进一步与待接合齿轮的齿圈接合而完成换档过程。

前言
汽车变速器中采用同步器,可以保证换档操作迅速、轻便无冲击,延长齿轮和传动系统的使用寿命,提高汽车在换档和加速起步时的动力性和经济性,改善驾驶舒适性的有效措施。同步器技术目前被广泛应用于各种车型上。同步器的应用是机械变速器发展过程中一次质的飞跃,在我国汽车行业标准QC/T29063中明确规定轻型汽车变速器前进档必需装有同步器结构,中型汽车除一档、倒档外,其余各档也必需装有同步器结构。随着同步器技术不断发展,对于提高变速器传动性能,具有十分重要的经济技术意义。
对于二档换一档的退档过程中,同理是齿轮P1和S1的减速度要比齿轮P2和S2要大。所以高档换低档是极其复杂的。在分开二档齿轮之前,齿轮S1的圆周线速度VS1比齿轮S2、P2、P1要大,如图3所示,齿轮P2和P1在t′x 时趋于零,齿轮S2和S1在tx 时趋于零,他们之间相距很大。根本不能相交,齿轮P1和S1圆周线速度永远没有相等的时间。所以,要想在瞬间内使这两个齿轮直接相啮合是不可能的。必须采取一种辅助方法使齿轮P1和S1圆周线速度接近。这就是通常的做法“两脚离合器”:
第一步踩下离合器踏板;
第二步将排档杆移至空档位置;
第三步再松开离合器踏板,稍加油门从a→b,使齿轮p1速度增高并超过齿轮S1的速度线。
第四步再踩下离合器踏板b→C,使齿轮p1速度迅速下降,在C点迅速换档。
这样就找到了时间t2 点,使齿轮P1和S1圆周线速相等。在这个过程中,驾驶员不但要有高超的实践经验和操作技能,而且劳动强度也很大。
汽车机械式变速器安装了同步器之后,就不需要“两脚离合器”的操作。减轻了驾驶员的劳动强度,减少换档时齿轮间的撞击,能准确无误地换档,增加了舒适性。
同步器发展仅有数十年的历史。自1912年奥地利的Humohries提出了采用摩擦式同步器之后,直到1926年才装到美国凯迪莱克汽车上。从此之后使用范围不断扩大,到目前为止凡是手动机械式汽车变速器都使用了同步器。
本手册是在综合同步器理论和实践研究的基础上编写而成。本书结构新颖,文字简洁,图文并茂,通俗易懂。内容包括:同步器结构形式,工作原理,设计参数,结构参数,以及影响同步器性能的因素。本手册可供从事汽车变速器的设计、生产、维修人员参考。
本手册经等人员审阅并提出修改意见,在此表示感谢。由于作者水平有限,难免有不足之处,请广大员工提出宝贵意见。
早期开发的同步器为常压式同步器,有锥形和片式两种。由于它不能保证被啮合齿轮在同步状态(即角速度相等)下实现换档,不能从根本上解决换档时啮合冲击问题,所以这种同步器目前已被淘汰。
目前汽车上广泛使用的惯性式同步器,主要有:锁销式同步器;锁环式同步器;锁环式多锥面同步器。除此以外还有增压式同步器。由于这种同步器对材料、热处理及制造精度均要求较高,目前国内采用较少。近几年来国外还开发了一种杠杆式同步器,主要用于倒档。这种同步器还处于试验状态中。下面分锁销式同步器、锁环式同步有良好的工作性能,对变速器提出以下基本要求:
1.应有合适的变速档位数和传动比,保证汽车具有良好的动力性和经济性指标。
2.较高的传动效率。
3.应有空档和倒档。
4.换档操纵迅速轻便、工作可靠,噪声小。
在手动机械式变速器中(Manual Transmission简称MT),同步器是改善换档性能的主要零部件。对减轻驾驶员的劳动强度,使操纵轻便,提高齿轮及传动系统的使用寿命,提高汽车行驶安全性和乘坐的舒适性,改善汽车起步时的加速性和经济性起着重要作用。

第一节结构参数设计
第二节结构参数设计对换档性能的影响
现以一个五档变速器为例,说明同步器在换档中的作用。
假如汽车正在二档位置上行驶,则变速器通过发动机传来的动力,经过第一轴上的齿轮A和中间轴常啮合齿轮B、齿轮P2传递给第二轴上的齿轮S2,使动力输出。这时齿轮P2和齿轮S2的圆周线速度相等,VS2=VP2。当汽车在良好的路面行驶,驾驶员此时要改善汽车行驶的经济性,要从二档换到三档上行驶,这时驾驶员就要把齿轮S2和P2分开,而把齿轮S3和P3接合上。此时中间轴上的齿轮P3的直径要比P2大。由于中间轴传动角速度ω不变,则Vp3>VP2。同理,由于第二轴上的齿轮S3的直径小于S2的直径,VS3<VS2。如果在时间t内踩离合器,由于第二轴与驱动桥、后轮、整车相连,转动惯量很大,齿轮的速度不可能很快降下来。这样,在时间t内,齿轮S2和S3的圆周线速度不相等,见图2所示。要经过相当长的时间tx,等后轮轴停止后,齿轮S2和S3的圆周线速度相等,同时为零。
同步器自问世以来,结构在不断变化,工作性能也在日趋完善。近些年来国外在同步器研究、设计、制造方面发展很快。我们在自主研发、制造与国外相比还存在很大差距,同步器的性能和可靠性还不能满足使用要求。因此我们要加强同步器方面的研究,缩小差距,力争赶超和超过国外先进水平。
第一章同步器的结构型式及其特点
汽车变速器中使用同步器,可以保证换档时齿轮不受冲击,延长齿轮的使用寿命,使汽车在起步、换档时的加速度和经济性得到改善。换档时加在齿套上的轴向力经柱销(或滑块)推动同步环使锥面相接触产生摩擦力矩,借此改变被啮合齿轮的转速以达到同步。
对于中间轴,是齿轮A、B随第一轴即离合器而转动。由于这一段的转动惯量小,离合器分离后,会在很短时间t′x 内停止转动,Vp3和VP2很快随第一轴的停止而趋于零。
当中间轴与第二轴以不同的速度降低的过程中,齿轮P3和S3圆周线速度相等,驾驶员就要巧妙地抓住这段时间,把齿轮P3和齿轮S3接合上。所以在低档换高档的过程中,全靠驾驶员的熟练操作和丰富经验,同时注意力也要特别集中。

绪论
汽车变速器是汽车传动系中的一个重要部件,它的功能是在不同的使用条件下,改变由发动机传到驱动轮上的转矩和转速,使得汽车得到不同的牵引力和车速,以适应不同的使用条件。同时也可以使发动机在最有利的工况范围内工作。
