Description

摩托车前传动装置 技术领域
本发明涉及到一种摩托车， 尤其是一种摩托车的前传动装置。 背景技术
摩托车前传动系统为摩托车前轮与其车身主体提供了衔接， 该系统保证了 车体与地面之间的联系， 从而保证了车轮与地面之间的接触。 车轮胎必须保持 三度活动自由：
1 . 摩托车轴承周围的交替回转带动着摩托车的前进， 该转动可以使无拘 束或者是被支配的 （刹车的情况或者是主动轮未启动状况）；
2 . 垂直性平移会使摩托车悬挂装置成为可能， 因此保证使用者拥有齐全 的设备以及安全的保障。 此稳定性由摩托车的悬挂装置控制 （弹簧和减震器）， 而悬挂装置控制又改变着速度， 传动装置所具有的几何理论定义了车轮下的行 程；
3 . 摩托车转向系统轴承周围的交替回转实现了使用者对摩托车的驾驶， 摩托车驾驶者通过对驾驶尬监控的办法支配着摩托车的运动， 车轮的运动又是 由摩托车的车把控制， 而车把的控制又是由传动装置所具有的几何理论实现的。
通常， 摩托车的套管式车叉实现了以上三个作用， 装配在转向系统柱周围 的该种车叉使使用者对摩托车的驾驶成为现实。 导向装置的外套和车叉管让悬 挂装置产生了纵向震动。
惯用的车叉虽然已经广为推广， 但是它本身所带的缺点制约着我们的思维。 它对转向系统和悬挂装置的兼并作用加大了系统的调整难度。 不难发现， 大量 确认本 参数都是互相关联的。
以下几个基本的几何参数影响着摩托车的相关运动： 轴距、 框架的角度、 框架或者是气流的迎面阻力以及元件之间的角度和空间。
利用此机械原理， 轴距、 框架的角度和气流的迎面阻力在悬挂装置插入的 过程中将会被改变。 所以摩托车的运动也将不再与悬挂装置降压或者升压后的 运动相同， 这使得套管式车叉的几何错误变得尤为显著。
另一方面， 所有作用于轮胎上的力被传导到转向系统柱的位置上。 这个位 置上的框一定会被极大地加强， 并在一个大大高于并且远离重心的位置区域上 达到一定的重量， 从而大大削减了摩托车的易操作性。 套管式车叉也同时有着 螺旋升降的趋势， 尤其当刹车力不对称的时候（只有一个刹车盘的情况）， 会在 车把上引发一个精确度的错误和对车手心理上造成可能导致人身危险的影响。 发明内容
为了解决现有技术的上述不足之处， 本发明提供了一种无套管式车叉的新 型摩托车前传动装置， 通过铰接的方式有机结合车把手、 车前轮和车身本体， 使得前车轮可以更大角度范围内自由转向， 同时整个车身受力均匀。
本发明是通过以下技术方案来实现的。
一种摩托车前传动装置， 包括前车轮、 车轮轴承和车把手， 还包括操纵臂、 悬挂臂、 上连接块、 支持架和连接杆;其中， 所述悬挂臂的前端与所述操纵臂的 下端相铰接， 所述悬挂臂的后端与车身主体或者发动机相铰接； 所述操纵臂的 下端通过车轮轴承和所述前车轮相连接； 所述操纵臂的上端一侧通过连接杆与 所述车把手铰接， 另一侧与所述上连接块铰接； 所述支持架分别和所述上连接 块、 所述车把手以及所述车身本体或者发动机相铰接。 所述悬挂臂呈 "V" 字形， 水平对称地分布在所述车身本体两侧。
所述悬挂臂的前端通过球形连轴节和所述操纵臂的下端相铰接， 所述悬挂 臂的前端和所述球形连接轴的两侧相连接； 所述悬挂臂的后端通过轴承与所述 车身本体或者发动机相铰接。
所述车轮轴承包括内圏和外圈， 所述车轮轴承的内圈与所述操纵臂的下端 固定连接， 所述车轮轴承的外圈与所述前车轮的轮辋固定连接。
所述车轮轴承的内圈有一个水平轴孔， 所述球形连轴节通过垂直于地面的 轴销安装在所述水平轴孔中。
在另一个实施例中， 所述的车轮轴承内圈有一个轴孔， 所述轴孔内安装有 向心汉关节轴承， 所述悬挂臂通过所述向心双关节轴承和所述操纵臂铰接。 所 述的向心双关节轴承包括内圈和外圈， 所述向心双关节轴承的内圈和外圈分别 可以独立自由转动。
所述上连接块通过一对互相垂直的轴承与所述操纵臂相铰接。
所述上连接块通过两个水平且中心轴线相重合的滚珠轴承与所述支持架相 铰接， 所述上连接块与所述支持架之间还连接有减震弹簧。
所述车把手和所述支持架之间通过轴承相铰接； 所述轴承包括通过上下两 组滚珠支承的内圈和外圈， 所述轴承的内圈与所述车把手固定连接， 所述轴承 的外圈与所述支持架固定连接。
本发明摩托车前传动装置通过铰接的方式， 有机结合车前轮、 车把手和车 身主体， 把摩托车行使过程中车前轮所受到的作用力分别通过悬挂臂、 上连接 以及减震弹簧传递到车身本体上， 使得整车受力均匀。 而且， 通过操纵臂和悬 挂装置来引导前车轮的转向， 克服了现有技术中的前叉装置对前车轮左右转向 角度的限制， 所以本发明可以使摩托车实现大角度的转向。 下面将结合附图， 通过优选实施例进一步阐述本实用新型。 附图说明

具体实施方式
图 1 为装有本发明摩托车前传动装置的摩托车结构示意图， 包括本发明摩 托车前传动装置和摩托车车身本体 10。 其中本发明摩托车前传动装置包括前车 轮 1、 操纵臂 2、 上连接块 3、 连接杆 4、 减震弹簧 5、 车把手 6、 悬挂臂 7和支 持架 8。
所述悬挂臂 7前窄后宽， 呈 "V" 字形， 水平并且对称地分布在所述车身本 体 10的两侧。 所述悬挂臂 7的前端与所述操纵臂 2的下端相铰接， 后端通过轴 承与所述车身主体 10相铰接。 所述操纵臂 2的下端通过车轮轴承 12与所述前 车轮 1相连。 所述操纵臂 2的上端一侧通过所述连接杆 4与所述车把手 6相铰 接， 另一側与所述上连接块 3相铰接。 所述车把手 6和所述支持架 8之间铰接, 且连有所述减震弹簧 5。所述支持架 8还同时与所述上连接块 3以及所述车身本 体 10铰接。
如图 2至图 3所示， 所述车轮轴承 12包括内圏 12a和外圈 12b， 所述内圈 12a和所述操纵臂 2的下端固定连接，所述外圈 12b固定在所述前车轮 1的轮辋 中央， 由此实现所述操纵臂 2和所述前车轮 1的连接。 所述内圈 12a中还有一 个水平轴孔， 球形连轴节 11安装在该水平轴孔中。 所述悬挂臂 7的前端分别与 所述球形连轴节 11的上下两侧相连接。 通过垂直于地面的轴销 11a把所述球形 连轴节 11固定在该水平轴孔中。
所述操纵臂 2和所述上连接块 3之间通过轴承 13a和 13b相铰接， 所述轴 承 13a和轴承 13b互相垂直， 因此可以实现所述操纵臂 2和所述上连接块 3之 间各个方向上的相对运动。
如图 5和图 6所示， 所述上连接块 3呈三角形， 其中部有两组滚珠轴承 14a 和 14b， 所述滚珠轴承 14a和 14b的中心轴线重合且处于水平位置。 所述滚珠轴 承 14a和 14b的内圈与所述支持架 8相固定连接， 所述滚珠轴 14a和 14b的 外圈与所述上连接块 3相固定连接。
如图 7和图 8所示， 所述车把手 6和所述支持架 8之间通过轴承 15实现餃 接。 所述车把手 6与所述轴承 15的内圈 15a固定连接， 所述支持架 8与所述轴 承 15的外圈 15b固定连接。 所述轴承 15的内圈 15a和外圈 15b之间通过上下 两组滚珠 15c支承。
图 9中， 所述连接杆 4两端分别带有一个球形铰， 其中一端与所述车把手 6 相连， 另一端与所述操纵臂 2的上端一侧相连。 在本发明的第二个实施例中， 悬挂臂的后端通过轴承跟摩托车的发动机相 铰接， 支持架也与摩托车的发动才 /^目铰接。操纵臂 2' 的下端和车轮轴承的内圈 12a' 可以设置多个对应的长形孔 2a' ， 用螺栓 2b' 穿过对应的所述长形孔 2a ' ， 用于固定所述操纵臂 2' 下端和所述车轮轴承的内圈 12a' 。 这样就可以根 据需要调节所述操纵臂 2' 与地面之间的角度。
如图 12所示， 在本发明第三个实施例中， 操纵臂 2' ' 和车轮轴承的内圈 15a' ' 有一个轴孔 15c' ' , 所述轴孔 15c' ' 内安装有向心双关节轴承 16 , 悬挂臂通过向心双关节轴承 16和所述操纵臂 2' ' 铰接。如图 11所示， 所述的 向心双关节轴承 16包括内圈 16a和外圏 16b， 所述双向心关节轴承的内圈 16a 和外圈 16b分别可以独立自由转动。
向心双关节轴承 16的内圈 16a可以自由转动， 同时其外圈 16b也可以独立 转动， 这样装有本发明的摩托车在行驶过程中， 前轮 1 转动更自由， 转动角度 就更大。
装有本发明摩托车前传动装置的摩托车在行驶过程中， 所述前车轮 1 的作 用力 2分别通过所述悬挂臂 7、所述上连接块 3 及所述减震弹簧 5传递到摩托 车车身主体上， 整个车身受到的应力分布均匀。 车身两侧对称分布的所述悬挂 臂 7在摩托车行驶过程中受力对称， 使得车身的平衡性更好。 根据需要， 悬桂 臂 7的横截面可以设计得更小， 从而减轻车身重量， 降低制造成本。
所述悬挂臂 7和所述操纵臂 2之间铰接， 且所述球形连轴节 11通过垂直于 地面的轴销水平安装在轴孔里， 这样所述操纵臂 2在控制前车轮 1运动的时候 就没有左右方向上外部限制， 所述前车轮 1的摆动角度可以更大， 更容易操控。 在发生强大的扭转变形时， 本发明仍可以保持很好的刚度。
本发明还可以根据实际需要调节所述操纵臂 2' 和地面的角度，所以能实现 在不更换任一部件的情况下， 改变车身的基本几何参数。
以上所揭露的仅为本实用新型的优选实施例而已， 当然不能以此来限定本 实用新型之权利范围， 因此依本实用新型申请专利范围所作的等同变化， 仍属 本实用新型所涵盖的范围。
