Description

一种反向三轮车 技术领域
本发明涉及三轮车零部件，具体涉及一种前面设置两个转向轮，后面设置一个驱动轮的反向三轮车。
背景技术
倒三轮车是前轮具有左、右各一轮，后轮具有一轮的三轮车，其中，两个前轮具有转向功能，而后轮具有驱动功能。目前，市场上的倒三轮车支撑结构包括车架、前两轮固定架、后平叉，所述车架，包括车架后段、车架中段、车架前段，所述的车架前段固定连接前两轮固定架，车架后段活动连接后平叉，前两轮固定架固定在前面两个车轮上，后中心独减震上端铰链固定在车架上，后中心独减震下端铰链固定在后平叉上，但由于车架和前两轮固定架采用的不同，造成整个倒三轮车的支撑结构不合理，存在前悬架结构分散不集中，倒三轮车车架前段的空间布置小的缺陷；另外，市场上的倒三轮的前两轮转向装置，包括连接在支撑架上的立管以及方向柱，所述的支撑架是指车架或者前悬挂等固定旋转机构零部件的固定件，方向柱带动万向节的转向臂对前轮方向进行控制，由于转向臂之间采用万向节连接的，而万向节之间配合需要旋转间隙较大，造成操作间隙大，相应速度慢；另外也有采用类似汽车上的齿条式传递，这种方式虽然旋转间隙小，但操作的动作范围大，通常需要将方向盘操作几圈才能将车轮方向旋转到合适位置，也不适合倒三轮车的方向把形式，所以需要提供一种相应速度快，旋转间隙小的适用于倒三轮车的前两轮转向装置。
发明内容
本发明技术方案所要解决的技术问题是提供一种倒三轮车支撑结构，解决目前前悬架结构分散不集中，倒三轮车车架前段的空间布置小的缺陷；
为解决上述技术问题，本发明的技术方案如下：
一种反向三轮车，包括支撑机构和转向装置，其中，支撑机构包括车架、前两轮固定架、后平叉；转向装置包括包括方向柱及连接在支撑架上的立管，所述车架，包括车架后段、车架中段、车架前段，所述的车架前段固定连接前两轮固定架，车架后段活动连接后平叉，前两轮固定架固定在前面两个车轮上，后中心独减震上端铰链固定在车架上，后中心独减震下端铰链固定在后平叉上，其特征在于，还包括有驻车锁止装置，驻车锁止装置控制固定前固定架的左右摆动；所述车架的后段包括左后上横管、左后斜后竖管、右后上横管、右后斜后竖管；所述车架的中段包括左中上横管、左中斜后竖管、左中下横管、左中斜前竖管、右中上横管、右中斜后竖管、右中下横管、右中斜前竖管；所述车架前段包括左前斜竖管、左前横管、右前斜竖管、右前横管；其中，左后上横管平滑连接左后斜后竖管后再平滑连接左中上横管再连接左前斜竖管再连接左前横管，左中下横管的前端与左中斜前竖管连接，左中下横管的后端与左中斜后竖管连接，左中斜前竖管与左前斜竖管连接，左中斜后竖管与左中上横管连接；右后上横管平滑连接右后斜后竖管后再平滑连接右中上横管再连接右前斜竖管再连接右前横管，右中下横管的前端与右中斜前竖管连接，右中下横管的后端与右中斜 后竖管连接，右中斜前竖管与右前斜竖管连接，右中斜后竖管与右后上横管连接；左后上横管、左后斜后竖管和右后上横管、右后斜后竖管之间形成的平行架之间连接有后中心独减震的上连接件，后中心独减震的下连接件设置在后平叉上，后平叉活动连接在左中上横管和右中上横管之间；左前横管、左前斜竖管和右前横管、右前斜竖管之间形成的平行架之间固定连接有方向立管固定架，方向立管固定架上固定连接有立管；所述的前两轮固定架，包括左固定座、右固定座，左固定座固定在左前轮的轮毂上，右固定座固定在右前轮的轮毂上，还包括有连接在车架主体前端的前悬架以及支撑臂组合，所述的前悬架包括中部设置有安装横置前减震的空腔、前上部设置的前上空腔、前下部设置的前下空腔、后下部设置的后下空腔；前悬架的前上空腔和前下空腔之间左边设置有左限位块，前上空腔和前下空腔之间右边设置有右限位块；支撑臂组合包括左上支臂、右上支臂、左下支臂前臂、右下支臂前臂、左下支臂后臂、右下支臂后臂，其中，左上支臂内端和右上支臂内端通过第一销轴铰链连接安装在前上空腔内；左下支臂前臂内端和右下支臂前臂内端通过第二销轴铰链连接安装在前下空腔内；左下支臂后臂内端和右下支臂后臂内端通过第三销轴铰链连接安装在后下空腔内；左上支臂设置在左限位块的上部，左下支臂前臂之间设置在左限位块的下部，右上支臂设置在右限位块的上部，右下支臂前臂设置在右限位块的下部；左上支臂、左下支臂前臂、左下支臂后臂的外端铰链连接在左固定座上；右上支臂、右下支臂前臂、右下支臂后臂的外端铰链连接在右固定座上；在左下支臂前臂和左下支臂后臂之间设置有前减震左连接件，在右下支臂前臂和右下支臂后臂之间设置有前减震右连接件，前减震左边与前减震左连接件连接，前减震右边与前减震右连接件连接。
采用上述技术方案的倒三轮车支撑结构，由于前悬架包括中部设置有安装横置前减震的空腔、前上部设置的前上空腔、前下部设置的前下空腔、后下部设置的后下空腔，将横向的前减震及支撑臂组合都集中设置在前悬架，前悬架结构集中，倒三轮车车架前段的空间布置较大，同时由于前减震横向设置在前悬挂的中间空腔位置，相对竖直的前减震而言，降低了减震的位置和整车的重心；另外采用铰链方式连接替换万向节连接方式，降低了对工艺的要求，降低了成本。
进一步，限定所述的左下支臂前臂和左下支臂后臂一体成型，所述的右下支臂前臂和右下支臂后臂对称的设计一体成型。采用一体成型和对称的设计结构一方面减少模具的投入，同时保证了支撑应力和前减震的固定位置。
另外，进一步限定左、右固定座的结构，左、右固定座也采用对称的设计一体成型，详细来说限定所述的左固定座包括左固定座本体、左上安装台、左下安装台，左固定座本体中心向左延伸出安装左前轮的左轮安装轴，左上安装台上铰链连接左上支臂，左下安装台上铰链连接左下支臂前臂和左下支臂后臂；所述的右固定座包括右固定座本体、右上安装台、右下安装台，右固定座本体中心向右延伸出安装右前轮的右轮安装轴，右上安装台上铰链连接右上支臂，右下安装台上铰链连接右下支臂前臂和右下支臂后臂。
本发明技术方案与现有技术相比具有以下优点：倒三轮车车架前段的空间布置较大，同时由于前减震横向设置在前悬挂的中间空腔位置，相对竖直的前减震而言，降低了减震的位置和整车的重心；另外采用铰链方式连接替换万向节连接方式，降低了对工艺的要求，降低了成本。
采用本发明技术方案的倒三轮车支撑结构，使用时，由于左上支臂、右上支臂、左 下支臂前臂、右下支臂前臂、左下支臂后臂、右下支臂后臂都是采用铰链连接的方式与左固定座、右固定座以及前悬架连接，依靠固定在下支臂上的横置的前减震左连接件、右连接件进行横向控制铰链旋转前悬挂上下移动受力，并通过左限位块、右限位块限定左上支臂、右上支臂、左下支臂前臂、右下支臂前臂的上下移动的位置，从而保证了固定架的稳定性；这种将前减震横置设置的方式，能更好的对支撑臂组合产生的力给予减震缓冲，前减震在使用过程中，其位置高低根据支撑臂组合的位置形状变化而进行变化，适用在行进动态中更舒适。
另外进一步限定所述的后平叉包括左右相互对称的左平叉和右平叉，左平叉包括左套管、左平叉支撑臂、后中心独减震左安装支耳，其中，左套管与左平叉支撑臂固定连接，左平叉支撑臂内端固定连接后中心独减震左安装支耳；右平叉包括右套管、右平叉支撑臂、后中心独减震右安装支耳，其中，右套管与右平叉支撑臂固定连接，右平叉支撑臂内端固定连接后中心独减震右安装支耳；左平叉和右平叉对称摆放通过平叉轴固定在车架上，后中心独减震的上端铰链连接在车架后段的上端，后中心独减震的下端铰链连接在后中心独减震左安装支耳和后中心独减震右安装支耳上。
采用上述技术方案的组合式后平叉，在轮胎更换，电机维修时候，只需要将平叉轴(一端是用螺母锁紧)的固定螺母松开，将后中心独减震下端的铰链轴松开，就能将左平叉取下，直接就可以在不取下后轮和右平叉的基础上更换轮胎和维修电机；另外，由于左平叉和右平叉是左右相互对称的形状，可以采用同一副模具进行制造，制作的模具也比固定一体式结构的小，模具容易制作，成本降低，互换性强。当然，根据安装的需要，也可以单独将右平叉取下，其效果和结构原理一样。
进一步，限定所述的后中心独减震左安装支耳设置在左平叉支撑臂内端下部，所述的后中心独减震右安装支耳设置在右平叉支撑臂内端下部。
由于平叉采用左右相互对称的左平叉和右平叉组合而成，作用在后轮中心的应力较大，传递到平叉轴中心，也就是左平叉和右平叉配合接触处受到的应力较大，所以设置成后中心独减震更适合这种组合式平叉，并且将安装支耳都设置在平叉支撑臂内端下部，有利于减少左平叉和右平叉配合接触处受到的应力变形，平叉下部的空间大，更方便安装后中心独减震。
驻车锁止装置，前两轮固定架包括支撑臂组合和前悬挂架，支撑臂内端铰链在三轮车的前悬挂架上，支撑臂外端铰链在前两轮固定座上，驻车锁止装置包括摆动片、锁钳及操作手柄，所述的摆动片固定安装在支撑臂的臂杆上，以被安装的支撑臂内端铰链中心进行旋转；所述的锁钳包括锁钳基座和至少一对夹持摩擦片，锁钳基座固定安装在前悬挂架上，夹持摩擦片能夹紧和松开摆动片；所述的操作手柄包括操作杆和锁定件，操作杆能操作夹持摩擦片处于夹紧摆动片或松开摆动片的状态，操作到状态后由锁定件对操作杆进行锁定。
采用上述技术方案的驻车锁止装置，专门适用在采用背景技术中所述的倒三轮车上，这种倒三轮车的前两轮固定架包括支撑臂组合和前悬挂架，支撑臂内端铰链在三轮车的前悬挂架上，支撑臂外端铰链在前两轮固定座上，由于专门设置了驻车锁止装置，驻车锁止装置包括摆动片、锁钳及操作手柄，手柄是采用可以自锁的结构设置在车架或者方向把上，这种自锁的技术方案可以采用背景技术中所述的中国公布(公告)的专利 CN104477311A；CN104386196A；CN202847937U专利公开的技术方案，本领域技术人员可以通过阅读上述专利文献就能得到具体结构限定，所以本开放式写法中不再作为必要的技术特征对这种自锁操作手柄的结构进行限定。
使用本发明的专利技术方案，在操作手柄没有锁止的状态下，这种摆动片在倒三轮车左右摆动(也就是支撑臂内端围绕铰链轴旋转)时，在锁钳的夹持摩擦片之间间隙来回在复摆动，一方面可以限位在行进过程中，根据不同的路况，借助夹持摩擦片的摩擦力，缓解倒三轮车前端左右摆动响应速度，提高不同路面情况下的逐渐适应性，另一方面又会辅助限定支撑臂的旋转间隙，减少支撑臂前后方向(轴向)上窜动；在驻车时，首先将车体摆正，然后将其锁止住，在锁止的状态时，锁钳的夹持摩擦片始终夹紧摆动片，从而使摆动片不能相对锁钳进行运动，也就锁定了支撑臂内端不能围绕铰链轴进行旋转，而锁钳又固定在前悬挂架上，前悬挂架又固定在车架上，从而在操作手柄锁止的情况下，车身不会再左、右倾斜运动，满足了车身摆正的要求。
进一步，限定支撑臂的具体结构以及驻车锁止装置零件的具体安装位置，限定所述的支撑臂组合包括左上支臂、右上支臂、左下支臂前臂、右下支臂前臂、左下支臂后臂、右下支臂后臂，其中，左上支臂内端和右上支臂内端通过右上支臂内端第一销轴铰链连接安装在前悬架板前上部；左下支臂前臂内端和右下支臂前臂内端通过第二销轴铰链连接安装在前悬架板前下部；左下支臂后臂内端和右下支臂后臂内端通过第三销轴铰链连接安装在前悬架板后下部；左上支臂、左下支臂前臂、左下支臂后臂的外端铰链连接在左固定座上；右上支臂、右下支臂前臂、右下支臂后臂的外端铰链连接在右固定座上；所述的摆动片固定安装在右上支臂的臂杆的内侧，以右上支臂内端铰链中心进行旋转，所述的锁钳基座固定安装在前悬挂架上部设置的前连接件上，所述的操作杆通过拉索或液压管连接锁钳，操作杆固定在方向把上或车架上。
采用直接将摆动片固定安装在右上支臂的臂杆的内侧，以右上支臂内端铰链中心进行旋转，所述的锁钳基座固定安装在前悬挂架上部设置的前连接件上，所述的操作杆通过拉索或液压管连接锁钳，操作杆固定在方向把上或车架上，结构紧凑，操作方便。当然，针对本领域技术人员，还可以将摆动片安装在其他的支撑臂上，如可以将摆动片固定安装在左上支臂的臂杆的内侧，以左上支臂内端铰链中心进行旋转；锁钳基座安装在前悬挂架上的位置也会根据摆动片的位置进行调整，根据位置关系，也可以将锁钳基座安装在车架上，本专利申请的技术方案中，前悬挂架也可以是车架的一部分，与车架一体设计。
更进一步，限定摆动片的具体形状，所述的摆动片包括固定部分和被夹持部分，其中，固定部分的形状为与右上支臂相互配合的直线板，固定部分上设置有与右上支臂上设置的安装柱相匹配的固定安装孔；被夹持部分的形状为与与夹持摩擦片相互配合的弧形板，弧形板的弧度的圆心与右上支臂内端第一销轴121轴121同心。采用这样形状的摆动片，既能保证安装方便，通过螺栓或螺母直接将摆动片固定部分固定在右上支臂，又能保证在支撑臂左右摆动时，被夹持部分和右上支臂同步同心旋转。
本发明技术方案采用铰链支撑臂组合的形式形成前两轮固定架，匹配上驻车锁止装置既能保证行驶过程中，支撑臂的灵活转动支撑，又能保证在驻车情况下，支撑臂不能再灵活转动，从而保证了在驻车情况下，车身不会再左、右倾斜运动，满足车身摆正的要求。
由于增加了方向立管固定架，方向立管固定架上固定连接有立管，方向立管固定 架设置在左前横管、左前斜竖管和右前横管、右前斜竖管之间形成的平行架之间，这样的结构改变了原来直接将车架的前段和方向立管是一体连接的结构，可以根据不同的造型设计改变方向立管固定架的位置和形状，没有必要改变整体车架的结构和性能，方向立管容易调整、更换、适用车型范围宽；同时，由于车架没有和立管连接，受方向立管转动的影响较小，所以车架的设计可以根据造型需求变化，前段的空间调整范围大。
进一步，限定所述的左后上横管、右后上横管为单臂梁，所述的单臂梁是指左后上横管、右后上横管除了本身的后端的支撑力外，没有在竖直方向的支持杆来提升支撑力。采用这种结构的左后上横管、右后上横管更有利于扩大左后上横管、右后上横管下部的空间位置，方便造型和储物。
另外，进一步限定所述的方向立管固定架包括横向连接件和向上延伸的固定管，横向连接件连接左前斜竖管和右前斜竖管，固定管下端与横向连接件固定连接，固定管上端与立管固定连接。采用这种单独结构的方向立管固定架，横向连接件的位置和固定管的位置可以在同一个车架上进行不同位置和角度的调整，从而适用不同风格的车型需要，即便是方向立管固定架损坏需要更换，也只需要更换单独的方向立管固定架即可，不需要更换整个车架，实现了分体的好处，扩大了适用范围。
另外，转向装置，包括方向柱及连接在支撑架上的立管，还包括第一旋转板、第一转向拉杆、第二旋转板、第一转轴件、左转向臂、右转向臂、左固定座、右固定座，其中，第一转轴件下端设置有安装左转向臂和右转向臂的空腔，第一转轴件上端设固定有第二铰链轴；第二旋转板的前端设置有第三铰链轴，第三铰链轴的下端固定在的支撑架上，第二旋转板的前端可旋转的套接在第三铰链轴的上端；方向柱可旋转的套接在所述的立管内，方向柱下端固定连接第一旋转板的一端，第一旋转板的另一端通过第一铰链轴与第一转向拉杆的前端铰链连接，第一转向拉杆的后端以及第二旋转板后端通过第二铰链轴铰链连接，第一转轴件的空腔内通过第四铰链轴将左转向臂、右转向臂铰链连接，左转向臂通过第五铰链轴与左固定座铰链连接，右转向臂通过第六铰链轴与右固定座铰链连接。
采用本发明技术方案的适用于倒三轮车的前两轮转向装置，使用时，偏摆形式的拉杆带动转向臂，转向臂推动固定座(固定座固定在前轮轮毂上)，从而带动前两轮转动，完成转向。
由于采用支撑臂之间的铰链连接取代了万向节连接，支撑臂之间的配合间隙减小，转向相应快，同时，具有铰链连接的支撑臂相对万向节连接的支撑臂的制作成本低，相对也降低了成本。
进一步，限定左转向臂的具体结构和具体连接方式，限定所述的左转向臂包括左转向臂本体和左拉杆，右转向臂包括右转向臂本体和右拉杆，通过第四铰链轴将左转向臂本体内端、右转向臂本体内端铰链连接，左转向臂本体外端与左拉杆内端采用可调式轴孔连接，右转向臂本体外端与右拉杆内端采用可调式轴孔连接，左拉杆外端通过第五铰链轴与左固定座铰链连接，右拉杆外端通过第六铰链轴与右固定座铰链连接。由于采用转向臂本体和拉杆分体的方式，方便制作，转向臂本体外端与拉杆内端采用可调式轴孔连接的方式，这种可调式的轴孔连接，可以对左右两边转向臂长度进行适量调节，补偿因制造造成的误差，更有利于安装和调试。这种可调式轴孔连接方式，可以是在转向臂本体外端设置成孔的方式，拉杆设置成轴的方式，轴上部分段设置台螺纹，拉杆穿过转向臂本体外端后，在转 向臂本体外端的两端采用外螺母的固定的方式将拉杆和转向臂本体外端位置锁定；当然，也可以反过来设计，即将转向臂本体外端设置成轴的方式，拉杆设置成孔的方式，也同样能实现技术效果。这种设计简单，能过很方便的进行调节。
进一步，限定固定座的结构和具体连接方式，限定所述的左固定座包括左固定座本体，左固定座本体前端设置有左转向连接台，左转向连接台与左拉杆外端通过第五铰链轴铰链连接，左固定座本体中心向左延伸出安装左前轮的左轮安装轴；所述的右固定座包括右固定座本体，右固定座本体前端设置有右转向连接台，右转向连接台与右拉杆外端通过第六铰链轴铰链连接，右固定座本体中心向右延伸出安装右前轮的右轮安装轴。
