Description

一种可摇摆的轴传动三轮车 技术领域
本发明涉及三轮车领域，尤其涉及一种可摇摆的轴传动三轮车。
背景技术
脚踏式三轮车是日常生活中较为常用的轻便交通工具，具有与自行车相同的轻便型，同时能够装载更多的物品。随着技术的进步，为了节省骑车人的体力，出现了电动助力式的三轮车，主要依靠曲柄轴处的扭力传感器检测到曲柄轴转动的信号，随后控制器控制电机为三轮车的驱动轮提供动力，从而节约骑车人的体力。该种助力式的三轮车与电摩式三轮车具有本质上的区别，如控制电机转动的方式不同，电动助力式的三轮车没有在车把上设置油门，骑行人通过脚踏驱动曲柄轴，曲柄轴触发扭力传感器，从而通过控制器控制电机驱动三轮车的驱动轮，安全性更加可靠。
关于三轮车拐弯容易翻车的原因主要是因为三轮车拐弯时，其重心会转移至前轮与拐弯时的外侧后轮之间，在离心力的作用下，车子就非常容易发生倾斜、翻车。目前有些国家强制规定，三轮车的后部通过宽度不能大于前车把的宽度，由于车把的宽度尺寸不能太大，使得三轮车的两个后轮之间的轮距较窄，并且两个后轮同轴驱动，拐弯时非常容易发生倾斜、侧翻。如日本市场需求的三轮车有这样两个要求。其一，三轮车的总宽度在600mm之内。其二，三轮车的车架由前后车架构成，前车架骑行时需有轴向左右摇摆功能；后车身且保持水平。这种三轮车在拐弯时，前车架相对于后车架可以进行一定角度的扭动，将车子的重心往弯道内侧移动，从而使三轮车拐弯时更加平稳、可靠。由于前车架其骑行摇摆时，还采用传统的链条直接驱动后轮，链条会呈现8字形扭曲，且左右扭曲的扭距是不同的。影响骑行安全，不便车把控制。所以这类三轮车被设计成多段式传动系统。如图1和图2，三轮车包括前车架101和后车架102，后车架102上设有向下延伸的支撑架1021，支撑架1021上设有摇摆机构111；前车架101与摇摆机构111连接，在前车架101后部一侧设置第一传动链轮103，在后 车架102的前部的另一侧设置第二传动链轮104，第一传动链轮103和第二传统链轮104相对设置并通过一多级万向节105连接，第一传动链轮103通过第一链条106与前车架101曲柄轴上的驱动链轮107传动连接；第二传动链轮104通过第二链条108与其中一个后车轮110上的后链轮109传动连接。前车架101通过摇摆机构111发生倾斜时，第一链条106、第一传动链轮103、驱动链轮107均随之倾斜，多级万向节105发生形态变化，以保证第二传动链轮104不受前车架101倾斜带来的应力；保持动力正常传输。但是上述技术方案中，动力需要经过第一链条106、第一传动链轮103、多级万向节105、第二传动链轮104、第二链条108、后链轮109才能到驱动后车轮110转动，属于多级传输，传动损耗较大，并且传统系统的零部件大大增加，装配过程复杂，通过同一链条联动的两个链轮轮距较大，并且是两组链条传动机构，可靠性差，传动系统离地间隙小，骑行过程中易与地面物体发生刮擦、磕碰，链条脱落的隐患无法解决，可靠性差，传动部件数量多，装配效率低。

具体实施方式
实施例一
参见图3至图15，按照发明提供的可摇摆的轴传动三轮车实施例，包括前车架1、后车架2和传动机构，所述前车架1上设有前车轮71(附图中的前车轮为结构示意图)，所述后车架2上对称设置有两个后车轮72(附图中的后车轮为结构示意图)，所述前车架1通过摇摆机构3可摇摆的与所述后车架2连接，所述传动机构包括设在所述前车架1上的第一扭矩输出组件4、设在所述后车架2上的第二扭矩输出组件5,所述第一扭矩输出组件4通过传动轴6将扭矩传输至所述第二扭矩输出组件5；所述第二扭矩输出组件5与两个后车轮72中的至少一个连动配合；所述摇摆机构3中部设有传动过孔331，所述传动轴6穿过所述传动过孔331，位于所述传动过孔331中的传动轴6的轴心线与所述摇摆机构3的轴心线重合。
本发明与现有技术相比，将传统三轮车的链条传动改为轴传动，并且传动轴6位于车架中线的所在平面中，首先，解决了现有技术中前车架1与后车架2之间发生摇摆时，传动系统需要随车架发生摆动，导致传动可靠性差的问题；其次，解决了现有技术中链条受到颠簸、震动易脱落，影响骑车体验，甚至影响安全的问题；再次，轴传动解决了现有技术中链条多级传动，导致的扭矩传输损耗大的问题；最后，位于传动过孔331中的一段传动轴6的中心线与摇摆机构3的旋转中心线重合，使得摇摆机构3发生摇摆时，传动轴6不会发生任何受力的情况，保证了本申请的传动性能；综上本申请中的轴传动机构相对于现有技 术中的链条传动机构，结构简单、易装配、可靠性高、传动机构具有免维护的优势。
参见图5至图8，根据发明上述的实施例，所述摇摆机构3包括第一摇摆件31、第二摇摆件32、连接轴33和弹性块34，所述第一摇摆件31包括摇摆轴311和设在所述摇摆轴311一端的第一连接部312，所述第二摇摆件32包括轴套321和套装在所述轴套321上的连接罩322，所述连接罩322上设有第二连接部3222；所述摇摆轴311的外壁设有外卡槽313，所述轴套321的内壁设有内卡槽3211；所述摇摆轴311的另一端插入所述轴套321中，所述外卡槽313与所述内卡槽3211相对，所述弹性块34的一端插入所述内卡槽3211，所述弹性块34的另一端插入所述外卡槽313；所述摇摆轴311中部设有第一插孔314，所述连接罩322上设有第二插孔3221，所述连接轴33穿过所述第二插孔3221和所述第一插孔314，将所述第一摇摆件31和所述第二摇摆件32可转动地连接；所述连接轴33的中部设有所述传动过孔331。上述弹性块34可采用橡胶弹性块。上述外卡槽313为多个并均匀设在摇摆轴311的外壁上，上述内卡槽3211为多个并均匀设在所述轴套321的内壁上。所述连接轴33上还设有锁紧螺母332，通过与锁紧螺母322配合将第一摇摆件31和第二摇摆件32可转动的连接。所述连接轴33的外壁与所述第一插孔314的内壁之间设有轴承35。摇摆机构静止状态时，弹性块34不发生形变，当第一摇摆件31相对于第二摇摆件32发生扭动时，弹性块34中部被挤压变形，随着弹性块34的自动恢复，第一摇摆件31也随之恢复到初始状态。第一摇摆件31和第二摇摆件32沿连接轴33扭动，因此，连接轴33的轴心线为摇摆机构3的轴心线。该摇摆机构3第一连接部312与三轮车的前车架1连接，第二连接部3222与三轮车的后车架2连接，尤其是传动过孔331的设置，可供传动轴6的穿过，使得摇摆机构3和传动轴6两个转动的部件，实现了有机结合，为轴传动的摇摆式三轮车的加工生产，提供了有利条件，有助于简化该种三轮车的传动机构，同时上述摇摆机构，结构简单紧凑、部件少、装配方便，生产成本低。
参见图13，根据发明上述的实施例，所述传动轴6包括至少两个分段传动轴6，相邻的两个分段传动轴6之间通过万向接头连接。采用上述结构的传动轴6，提高了第一扭矩输出组件4与第二扭矩输出组件5位置设定的灵活性，即第一扭 矩输出组件4的输出端与第二扭矩输出组件5的输入端是否在同一高度，或二者之间的连线是否为直线，均不会影响扭矩的传输，提高了车架设定的灵活性，扩宽了传动轴6与车架的匹配度，同时降低了车架的精度要求，提高了产品的良品率。
参见图12和图13，根据发明上述的实施例，所述传动轴6包括第一分段传动轴61、第二分段传动轴62和第三分段传动轴63，所述第一分段传动轴61和第二分段传动轴62通过第一万向接头64连接，所述第二分段传动轴62和所述第三分段传动轴63通过第二万向接头65连接，所述第一分段传动轴61与所述第一扭矩输出组件4配合，所述第三分段传动轴63与所述第二扭矩输出组件5配合。本实施例采用上述三段式的传动轴6，再不影响车架设计的前提下，最少得使用万向接头，保证了传动过程顺畅度，以及传动的可靠性。
参见图3、图4、图9、图11、图13和图14，根据发明上述的实施例，所述前车架1包括组件安装箱11、设在所述组件安装箱11上中空连接梁12，所述中空连接梁12的一端与组件安装箱11连接，所述中空连接梁12的另一端与摇摆机构3连接，所述传动轴6穿设在所述中空连接梁12内；所述第一扭矩输出组件4设在所述组件安装箱11中。上述前车架1的结构使得第一扭矩输出组件4和传动轴6均被前车架1包覆，传动轴6穿设在中空连接梁12中，在不改变车架基本构造的情况下，使得本发明中的扭矩输出组件、传动轴6均被封闭在了车架中，避免了外界雨水、砂砾的沾染，保证了传动系统的可靠性、安全性。所述组件安装箱11上设有前车梁13，所述前车梁13上设有前叉及车把，所述前车轮71设在所述前叉上。所述传动轴6一端与所述第一扭矩输出组件4配合，所述传动轴6的另一端穿过所述传动过孔331与所述第二扭矩输出端组件配合,还包括车座、设在曲柄上的脚蹬等部件，均是三轮车上的现有技术，此处不再详细赘述。
参见图3、图4、图9、图11、图13和图14，根据发明上述的实施例，所述后车架2包括车轮架21和设在所述车轮架21上的齿轮箱22，所述齿轮箱22与所述摇摆机构3连接，所述第二扭矩输出组件5设在所述齿轮箱22中，所述后车轮72设在所述车轮架21上。齿轮箱22的设置保证了第二扭矩输出组件5处于一个封闭的环境中，结合上述第一扭矩输出组件4、传动轴6均被封闭在车架中，使得本 发明的传动系统完全被封闭在了车架中，在车架不受到外力损坏的情况下，可以实现终身免维护，大大提高了三轮车的可靠性，延长了产品的使用寿命。
参见图3和图4，根据发明上述的实施例，所述车轮架21包括框架211、对称设在所述框架211上的两个车轮安装件212、设在所述车轮安装件212上的车轮传动轴213，车轮传动轴213可转动地设在车轮安装件212上，所述后车轮72设在所述车轮传动轴213上，所述第二扭矩输出组件5至少与一个车轮传动轴213连接。该种车轮架21结构简单、装配方便，通过车轮传动轴213将扭力传送至后车轮72上，与现有技术中的车轮轴不转，后车轮72上装链轮从而被链条48驱动自转相比；后车轮72的拆装无需拆装传动机构中的任何零部件(如现有技术中需要拆装链条48等)，简化了后车轮72，尤其被驱动的后车轮72的装配过程，提高了装配效率。
参见图3和图4，根据发明上述的实施例，所述车轮安装件212上设有刹车片机构214，所述后车轮72上设有刹车鼓或刹车盘，所述刹车片机构214与所述刹车鼓或刹车盘配合。盘式刹车和鼓式刹车均为现有技术中较为成熟的机构，此处不再详细赘述。本实施例优选在后车轮72上设置刹车鼓，采用上述刹车片机构214保证了本发明刹车的可靠性，从而保障了骑车人的安全。
参见图9至图12，根据发明上述的实施例，所述第一扭矩输出组件4包括可转动地设在所述前车架1上的中轴41和后轴42、设在所述中轴41上的前链轮43、设在所述中轴41两端的曲柄44、设在所述后轴42上的后链轮45和第一锥齿轮46，所述前链轮43和后链轮45通过链条48连动配合，所述传动轴6上设有第二锥齿轮47，所述第一锥齿轮46和所述第二锥齿轮47啮合。该种第一扭矩输出组件4结构简单、装配灵活，尤其是适用于不同直径后车轮72的三轮车，当被驱动轮发生大小变化时，只需更换一个适配的后链轮45即可实现速比的调整，而无需对整套第一扭矩输出组件4进行调整，该种结构对于生产多种不同型号的车企来说，减少了零部件的种类，有助于组件流水线的标准化设置，提高生产效率，缩减零部件的研发成本。
参见图9至图12，根据发明上述的实施例，所述中轴41和后轴42平行设置，所述传动轴6的与所述后轴42垂直。便于零部件的装配、保证传动机构的可靠性、 稳定性。所述第一扭矩输出组件4还包括与所述链条48压紧配合的涨链轮49。涨链轮49的设置可以将松垮的链条48压紧，保证一链条48与多种不同大小链轮的适配性，第一扭矩输出组件4中的链条48与前后链轮适配之后处于松垮的状态，采用涨链轮49弹性压紧，第一可避免链条48的脱落；第二当后链轮45或前链轮43发生直径变化时，仍旧可以采用原来的链条48，而无需调整链条48的长短。
参见图4、图9、图13至图17，根据发明上述的实施例，所述第二扭矩输出组件5包括设在所述后车架2上的扭矩输出轴51，所述传动轴6通过第二齿轮副连动所述扭矩输出轴51，所述传动轴6与所述第二齿轮副之间或者所述扭矩输出轴51与所述第二齿轮副之间设有离合组件，本实施例中的离合组件设在所述传动轴6与所述第二齿轮副之间，所述扭矩输出轴51与两个后车轮72中的至少一个连动配合。所述扭矩输出轴51通过万向传输轴57，与两个后车轮72中的至少一个连动配合，所述万向传输轴57一端通过第三万向接头58与扭矩输出轴51连接，所述万向传输轴57的另一端通过第四万向接头59与车轮传动轴312连接。本实施例中的扭矩输出轴51与其中一个后车轮72连动配合，上述第二扭矩输出组件5有效的将扭矩从传动轴6传输至与其垂直的扭矩输出轴51上，同时结构简单、部件少，装配方便，可靠性高，离合组件的设置保证了传动轴6静止状态时，后车轮72仍旧可以向前转动，符合传统传动机构的骑行习惯。
参见图13至图17，根据发明上述的实施例，所述第二齿轮副包括啮合的第三锥齿轮53和第四锥齿轮54，所述第四锥齿轮54设在所述扭矩输出轴51上，所述传动轴6通过离合组件连动所述第三锥齿轮53。所述离合组件包括设在所述第三锥齿轮53上的扭矩输入轴52、设在所述扭矩输入轴52上的第一端面棘齿521、滑动卡装在所述传动轴6上的内花键套55、推动所述内花键套55向所述第一端面棘齿521贴靠的弹性件56；所述扭矩输入轴52的一端与所述第三锥齿轮53连接，所述扭矩输入轴52的另一端设有所述第一端面棘齿521，所述传动轴6外壁上设有外花键66，所述内花键套55与所述外花键66滑动卡接配合，所述内花键套55与所述第一端面棘齿521相对的一端设有第二端面棘齿551，所述第一端面棘齿521与所述第二端面棘齿551配合。传动轴6正转即传动轴6驱动第二扭矩传输组件带动后车轮72向前转动时，此时第一端面棘齿521和第二端面棘齿551为啮合 状态并可带动第二端面棘齿551随之转动；当传动轴6反转时，第一端面棘齿521则无法与第二端面棘齿551啮合，也就无法带动第二端面棘齿551随之转动，同时，当向前转动的后车轮72带动第二端面棘齿551转动时，第二端面的棘齿无法与第一端面棘齿521啮合，也就无法带动第一端面棘齿521转动。上述离合组件结构简单、紧凑，设计巧妙，零部件少。所述弹性件56为套装在传动轴6上的弹簧。弹性件56采用弹簧，装配方便、成本低、可靠性高。所述扭矩输入轴52与所述传动轴6相对的一端设有定位插孔522，所述传动轴6的端部插入所述定位插孔522。该结构保证了传动轴6、离合器和扭矩输入轴52之间的联动的可靠性。所述第三锥齿轮53、扭矩输入轴52、第一端面棘齿521为一体成型结构。便于部件的加工、装配，同时保证了零部件的精度。
参见图1和图2，根据发明上述的实施例，还包括设在所述前车架1或后车架2上的蓄电池8，设在所述前车轮71上的助力电机(图中未示出)，设在所述第一扭矩输出组件4中的扭力传感器9，所述扭力传感器9与所述助力电机电连接，所述蓄电池8与所述扭力传感器9和所述助力电机连接。本实施例中的蓄电池8设在所述前车架1上，将上述结构用于电动助力的三轮车上时，大大提升了电动助力三轮车的可靠性，骑行感受大大提升。
根据发明上述的实施例，所述扭力传感器9上设有扭力触发孔，所述中轴41穿设在所述扭力触发孔中，中轴41转动触发所述扭力传感器。该种结构的扭力传感器，可直接通过转轴触发，即电动助力三路车极度匹配，有助于简化第一扭矩输出组件4的整体构造。
实施例二
本实施例与上述实施例一结构大致相同，唯有第一扭矩输出组件结构不同，所述第一扭矩输出组件4包括可转动地设在前车架1上的中轴41、设在所述中轴41两端的曲柄44，所述中轴41通过第一齿轮副连动所述传动轴6。该第一扭矩输出组件4结构简单、部件少、装配方便。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行变化，本发明的范围由所附权利要求及其等同物限定。
