第三章变速器,第五节分动器1

第三章变速器,第五节分动器1

§3.5分动器一.基本概念1.分动器的作用:用于越野车,使变速器输出的动力分配到各驱动桥。

2.在传动系中的安装布置位置:布置在变速器之后---即变速器输出的动力通过传动轴输入给分动器;分动器再向前桥、后桥(4×4)或其它多个驱动桥(6×6及以上的越野车)分别输出动力。

参见图3-25。

3.分动器的档位设置:一般设高、低2个档。

4.分动器前桥使用:▲好路行驶:不接前桥。

此时前桥为从动桥,可避免功率消耗及轮胎、传动系零件磨损。

只后桥或其它驱动桥驱动。

▲坏路行驶:接前桥。

此时前桥为转向驱动桥。

全轮驱动。

可防止其它驱动桥过载。

5.接、退前桥与挂、退低速档的关系:非先接上前桥,不得挂入低速档;非先退出低速档,不得摘下前桥。

或者这样说:在进入坏路行驶之前,先接上前桥,再挂入低速档;在进入好路行驶时,先退出低速档,再摘下前桥。

二.应用实例1.BJ2020吉普车分动器(见图3-26)该分动器设有2个操纵杆——一个用于换挡;一个用于接、摘前桥。

换档方式:滑动齿轮;接前桥方式:接合套。

▲空档:图示位置;分动器前、后轴均无动力输出。

▲高速档:换挡滑动齿轮10前移通过花键与齿轮9联接,不接前桥;只后桥驱动;传动比i H=(Z11/Z2)×(Z9/Z11)=(31/20)×( 24/31)= 1.2▲低速档:先接前桥——用接合套6,换挡滑动齿轮10后移与齿轮4啮合;全轮驱动;传动比i D=(Z11/Z2)×(Z10/Z4)=(31/20)×(41/24)=2.648退出低速档:先将换挡滑动齿轮10退出啮合;再摘下前桥接合套。

2.BJ2021(切诺基)吉普车分动器(见图3-29)分动器设有一个操纵杆。

接前桥与换挡均由这一个操纵杆来完成。

操纵杆有4个位置如下:▲4L(4轮低速驱动):接合套——前移(左移);锁销式同步器——后移(右移)。

传动比i4L=(Z11/Z2)×(Z4/Z8)——后桥输出=(Z11/Z2)×(Z9/Z8)——前桥输出。

东风EQ1092F型汽车分动器的设计

东风EQ1092F型汽车分动器的设计

摘要东风EQ1092F型汽车作为我国较先进的军用和民用汽车,有着广泛的用途和重要的作用。

在多轴驱动的汽车上,为了将输出的动力合理的分配给各驱动桥,设有分动器。

分动器的功用就是将变速器输出的动力分配到个驱动桥,并且进一步增大扭矩。

分动器也是一个齿轮传动系统,它单独固定在车架上,其输出轴与分动器的输出轴用万向传动装置连接,分动器的输出轴有若干根,分别经万向传动装置与各驱动桥相连。

越野汽车在良好的道路行驶时,为减少功率消耗及传动系机件和轮胎磨损,一般要切断通向前桥的动力。

在越野行驶时,根据需要接合前桥并采用低速档,增加驱动轮数和驱动力。

本文概述了分动器的现状和发展趋势,介绍了分动器领域的最新发展状况,对工作原理做了阐述。

本设计选用机械式分动器,其具有结构简单、传动效率高、制造成本低和工作可靠等优点。

主要说明了三轴式分动器的设计和计算过程,选择合理的结构方案进行设计,对分动器高低档齿轮和轴以及轴承做了详细的设计计算,并进行了受力分析、强度和刚度校核计算,对一些标准件进行了选型以及壳体得设计。

关键词:分动器;三轴式;高低档;校核;齿轮传动。

ABSTRACTThe DongfengEQ1092 cars are more advanced military and civilian cars, which are used widely and take the important role. In order to output the power to drive axle reasonably we settle transfer case drive in the car. The function of transfer case is output the power which from the gear box to drive axle and increase the torque. T he transfer case is a gear transmission system .It is fixed on the frame alone. The output axis and the transfer case output axis are connected by universal driven device .There are several output axis in transfer case, which link to driving axle by universal driving device .When the cross country vehicle running on the good way ,it always cut down the power to front axle in order to reduce consumption of transmitting mechanism and wheel. According to the need ,the cars connect the front axis and use low speed when in the off-road driving to increase the number of driven wheels and drive power. This paper outlines the transfer case and its further development meanwhile describe the theory of work. This design takes mechanical transfer case. It has a simple structure, high transmission efficiency, low manufacturing cost and working and reliable. Mainly to explain the three-axis sub-actuator design and calculation process, a reasonable choice to design the structure of the program. Accounting the low and high gear of transfer case and drive axis detailedly and analyses the stress and strength . Carrying out the type selected and shell design in a number of standard parts.Keywords:Thansfer; Triaxial type; Check; High low-grade; Gear transmission目录摘要 (I)ABSTRACT (II)第1章绪论 (1)1.1 概述 (1)1.2 分动器类型和发展 (1)1.3 分动器的功用及意义 (2)1.4 设计内容 (3)第2章分动器结构的确定及主要参数的计算 (4)2.1 设计所依据的主要技术参数 (4)2.2分动器的设计要求 (4)2.3 分动器结构方案的选择 (4)2.4 传动方案 (5)2.5 齿轮的安排 (5)2.6 换挡结构形式 (6)2.7分动器壳体 (6)2.8分动器的操纵机构设计 (7)2.9 传动比的计算 (7)2.10 中心距A确定 (8)2.11 本章小结 (9)第3章分动器的齿轮设计 (10)3.1 模数的确定 (10)3.2 齿形压力角及螺旋角 (10)3.3 齿宽 (11)3.4 各档齿轮齿数的确定 (11)3.4.1 低速档齿轮副齿数的确定 (11)3.4.2 对中心距进行修正 (12)3.4.3 确定其他齿轮的齿数 (13)3.5 齿轮损坏的原因和形式 (14)3.6 齿轮的材料选择 (15)3.7 齿轮的强度计算 (16)3.7.1 轮齿的弯曲应力 (16)3.7.2 轮齿触应接力 (19)3.8 本章小结 (22)第4章轴的设计 (23)4.1轴的尺寸初选 (23)4.2 轴的结构设计 (23)4.3 花键的形式和尺寸 (26)4.4 轴承的设计 (26)4.5齿轮和轴上的受力计算 (28)4.6 轴的强度校核 (30)4.7 本章小结 (33)结论 (34)参考文献 (35)致谢 (36)附录 (37)第1章绪论1.1 概述东风EQ1092F型汽车作为我国较先进的军用和民用汽车,有着广泛的用途和重要的作用[17]。

They can be used in numerous applications in both open and closed loop circuits.Series F12 conforms to current ISO and SAE mounting flange and shaft end configu -rations. A very compact cartridge version is also available.Frame sizes: F12-30, -40, -60, -80, -90, -110, -125, -150, -250.Thanks to the unique spherical piston de-sign, F12 motors can be used at unusually high shaft speeds. Operating pressures to 480 bar provides for the high output power capability.The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor/pump.The laminated piston ring offers important advantages such as low internal leakage and thermal shock resistance.The pump version has highly engineered valve plates for increased selfpriming speed and low noise, available with left and right hand rotation.The F12 motors produce very high torque at start-up as well as at low speeds.Our unique timing gear design synchronizes shaft and cylinder barrel, making the F12 very tolerant to high ’G’ forces and torsional vibrations.Heavy duty roller bearings permit substan-tial external axial and radial shaft loads.The F12’s have a simple and straightfor-ward design with very few moving parts, making them very reliable motors/pumps.The unique piston locking, timing gear and bearing set-up as well as the limited num-ber of parts add up to a very robust design with long service life and, above all, proven reliability.F12 cross section1.

例如,如果一辆前轮驱动的汽车两前轮都陷入沟中(这种情况在坏路上经常会遇到),那汽车就无法将发动机的动力通过车轮与地面的磨擦产生驱动力而继续前进。

而假如这辆车的四个轮子都能产生驱动力的话,那么,还有两个没陷入沟中的车轮能正常工作,使汽车继续行驶。

在多轴驱动的汽车上,为了将输出的动力分配给各驱动桥设有分动器。

1.1 毕业设计任务及要求题目:EQ2080型汽车分动器设计设计参数:课题内容:完成分动器的选型、设计计算并绘制相关图纸。

装配图1张(0号图);齿轮零件图4张(2号图);输入、输出轴,中间轴3张(2号图);动力传动示意图1张(2号图)。

其中要有计算机绘制的图样。

1.2 分动器的功用和设计要求分动器的功用就是将分动器输出的动力分配到各驱动桥,并且进一步增大扭矩。

分动器也是一个齿轮传动系统,它单独固定在车架上,其输入轴与分动器的输出轴用万向传动装置连接,分动器的输出轴有若干根,分别经万向传动装置与各驱动桥相连。

汽车全轮驱动,可在冰雪、泥沙和无路的地区地面行驶。

对分动器的设计要求要满足以下几点:1)便于制造、使用、维修以及质量轻、尺寸紧凑;2)保证汽车必要的动力性和经济性;3)换档迅速、省力、方便;4)工作可靠。

不得有跳档及换档冲击等现象发生;5)分动器应有高的工作效率;6)分动器的工作噪声低。

2 分动器结构方案的选择分动器的结构形式是多种多样的,各种结构形式都有其各自的优缺点,这些优缺点随着主观和客观条件的变化而变化。

因此在设计过程中我们应深入实际,收集资料,调查研究,对结构进行分析比较,并尽可能地考虑到产品的系列化、通用化和标准化,最后确定较合适的方案。

机械式具有结构简单、传动效率高、制造成本低和工作可靠等优点,在不同形式的汽车上得到广泛应用。

本设计采用的结构方案如图2-1所示。

图 2-1 分动器传动示意图2.1 传动方案分动器的设计类比于变速器和减速器的设计。

现在汽车大多数都采用中间轴式变速器,由《汽车构造》中EQ208型汽车分动器的结构图,采用输入轴与后轮输出轴同轴的形式,输入轴的后端经轴承在后轮输出轴的轴孔内,后轮输出要经过两对齿轮副的传递,因此传动效率有所降低。

2.2 齿轮的安排各齿轮副的相对安装位置,对于整个分动器的结构布置有很大的影响,要考虑到以下几个方面的要求:1)整车总布置根据整车的总布置,对分动器输入轴与输出轴的相对位置和分动器的轮廓形状以及换挡机构提出要求2)驾驶员的使用习惯3)提高平均传动效率4)改善齿轮受载状况各挡位齿轮在分动器中的位置安排,考虑到齿轮的受载状况。

承受载荷大的低挡齿轮,安置在离轴承较近的方,以减小铀的变形,使齿轮的重叠系数不致下降过多。

分动器齿轮主要是因接触应力过高而造成表面点蚀损坏,因此将高挡齿轮安排在离两支承较远处。

该处因轴的变形而引起齿轮的偏转角较小,故齿轮的偏载也小。

2.3 换档结构形式目前用于齿轮传动中的换挡结构形式主要有三种:1)滑动齿轮换挡通常是采用滑动直齿轮进行换挡,但也有采用滑动斜齿轮换挡的。

滑动直齿轮换挡的优点是结构简单、紧凑、容易制造。

缺点是换挡时齿端面承受很大的冲击,会导致齿轮过早损坏,并且直齿轮工作噪声大。

所以这种换挡方式,一般仅用在较低的档位上,例如变速器中的一挡和倒挡。

采用滑动斜齿轮换挡,虽有工作平稳、承裁能力大、噪声小的优点,但它的换挡仍然避免不了齿端面承受冲击。

2)啮合套换挡用啮合套换挡,可将构成某传动比的一对齿轮,制成常啮合的斜齿轮。

而斜齿轮上另外有一部分做成直的接合齿,用来与啮合套相啮合。

这种结构既具有斜齿轮传动的优点,同时克服了滑动齿轮换挡时,冲击力集中在1~2个轮齿上的缺陷。

因为在换挡时,由啮合套以及相啮合的接合齿上所有的轮齿共同承担所受到的冲击,所以啮合套和接合齿的轮齿所受的冲击损伤和磨损较小。

它的缺点是增大了分动器的轴向尺寸,未能彻底消陈齿轮端面所受到的冲击。

本设计中倒挡采用这种换挡方式。

3)同步器换挡现在大多数汽车的变速器都采用同步器。

使用同步器可减轻接合齿在换挡时引起的冲击及零件的损坏。

并且具有操纵轻便,经济性和缩短换挡时间等优点,从而改善了汽车的加速性、经济性和山区行驶的安全性。

其缺点是零件增多,结构复杂,轴向尺寸增加,制造要求高,同步环磨损大,寿命低。

但是近年来,由于同步器广泛使用,寿命问题已解决。

比如在其工作表面上镀一层金属,不仅提高了耐腐性,而且提高了工作表面的摩擦系数。

3 分动器主要参数的选择 3.1传动比分配高速级传动比:08.1i =高;低速级传动比:05.2i =低。

3.2 中心距A将中间轴与第二轴之间的距离称为中心距A 。

它是一个基本参数,其大小不仅对分动器的外形尺寸、体积个质量大小,而且对轮齿的接触强度有影响。

中心距越小,齿轮的接触应力越大,齿轮寿命越短。

因此,最小允许中心距应当由保证轮齿有必要的接触强度来确定。

分动器的轴经轴承安装在壳体上,从布置轴承的可能与方便和不影响壳体的强度考虑,要求中心距取大些。

4 分动器齿轮参数的确定 4.1 模数齿轮模数是一个重要参数,并且影响它的选取因素又很多,如齿轮的强度、质量、噪声、工艺要求、载荷等。

决定齿轮模数的因素很多,其中最主要的是载荷的大小。

由于高档齿轮和低档齿轮载荷不同,股高速挡和低速档的模数不宜相同。

从加工工艺及维修观点考虑,同一齿轮机械中的齿轮模数不宜过多。

根据国家标准GB1357—78的规定,选取各齿轮副模数如下:常啮合齿轮:m n =4mm ; 低速档:m n =4mm , 高速挡:m n =3mm 。

啮合套采用渐开线齿形,取m=3mm 。

4.2 压力角α压力角较小时,重合度较大,传动平稳,噪声较低;压力角较大时,可提高轮齿的抗弯强度和表面接触强度。

对于轿车,为加大重合度以降低噪声,应取用小些的压力角;对于货车,为提高齿轮承载能力,应取用大些的压力角。

实际上,因国家规定的标准压力角为ο20,所以分动器齿轮采用的压力角为ο20。

4.3 螺旋角β螺旋角β一般范围为10°~35°。

螺旋角增大使齿轮啮合系数增加、工作平稳、噪声降低、另外齿轮的强度也有所提高。

但螺旋角太大,会使轴向力及轴承载荷过大。

初选低速档啮合齿轮螺旋角β=20°。

关于螺旋角的方向,输入轴齿轮采用右旋,这样可使第一轴所受的轴向力直接经过轴承盖作用在分动器壳体上,避免了因轴向力一二两轴抱死的现象。

中间轴齿轮全部采用左旋,因此中间轴上同时啮合的两对齿轮轴向力方向相反,轴向力可互相抵消一部分。

4.4 齿宽齿轮宽度大,承载能力高。

但齿轮受载后,由于齿向误差及轴的挠度变形等原因,沿齿宽方向受力不均匀,因而齿宽不宜太大。

齿宽可根据下列公式初选:直齿轮b=(4.5~7.5)m,斜齿轮b=(6.0~8.5)m n 。

综合各个齿轮的情况,均为斜齿轮,齿宽选为30mm 。

4.5 各档齿轮齿数的分配 4.5.1 确定低速档齿轮副齿数在初选中心距、齿轮模数和螺旋角以后,可根据档数、传动比和传动方案来分配各档齿轮的齿数。
