具体实施方式
下面详细描述本发明的实施例，参考附图描述的实施例是示例性的，下面详细描述本发明的实施例。
下面参考图1-图11描述根据本发明实施例的实施例的混合动力总成1000，该混合动力总成1000应用于全地形车中。
如图1所示，根据本发明实施例的混合动力总成1000可以包括：发动机100和发电机200，发电机200设置于发动机100的轴向一侧，例如，发电机200设置于发动机100的右侧。其中，发动机100和发电机200动力传递，发动机100带动发电机200工作，发电机200会产生电能，发电机200与全地形车的动力电池和电动机相连接，动力电池与电动机相连接，这样发电机200的电能，可以供给电动机，从而可以驱动全地形车运动。
由此，由发动机100和发电机200组成的混合动力总成1000，可以将利用发动机100产生的动力转化为电能，再供给电动机，从而可以有效增加全地形车的续航里程，可以解决动力不足的问题，而且由于发电机200设置于发动机100的一侧，混合动力总成1000体积小，占用空间小，整体性更好。需要说明的是，混合动力总成1000内的发动机100可以保证持续正常工况工作，从而可以提高能效，可以减少能源的浪费，以及可以减少有害气体的排放。
如图2所示，发动机100包括曲轴10和曲轴箱20，曲轴10安装于曲轴箱20，曲轴10的轴端(即右侧轴端)伸出曲轴箱20，曲轴10的轴端可以方便发动机100与发电机200动力传递。
如图3和图4所示，发电机200包括：电机安装盖210、电机壳220、电机盖230、定子240和转子250，电机安装盖210安装于曲轴箱20的一侧，电机壳220安装于电机安装盖210和电机盖230之间，定子240固定于电机壳220内，转子250设置于定子240的内周，而且转子250相对定子240可以转动，转子250与曲轴10的轴端传动。也就是说，曲轴10的轴端实质上穿过电机安装盖210后与转子250相配合，然后带动转子250转动，以进行发电。此种方式可以使得发动机100和电动机200集成度高，传动效率高。
由此，通过设置电机安装盖210，发电机200可以牢靠安装在曲轴箱20的一侧，可以进一步地减小混合动力总成1000的体积，并且，通过设置电机安装盖210、电机壳220和电机盖230，可以合理安装定子240和转子250，可以保证两者的安装可靠性，以及可以保证曲轴10的轴端和转子250的传动可靠性。
根据本发明的一个可选实施例，转子250形成有转子孔，曲轴10的轴端穿过转子孔，而且曲轴10的轴端与转子250传动。也就是说，转子250套设在曲轴10的轴端上，然后两者套设配合，从而可以更好地保证同步转动，可以实现发动机100和发电机200之间的动力传递，可以保证保证两者的动力传递稳定性。
一种可选地，转子250在转子孔处形成有内花键，曲轴10的轴端形成有外花键，内花键与外花键花键配合。内花键和外花键的配合，简单可靠，而且易于实施。
另一种可选地，如图3和图4所示，转子孔形成有内锥面，曲轴10的轴端形成有外锥面11，内锥面与外锥面11相互配合。内锥面和外锥面11可以相互贴靠配合，这样可以使得转子250能够牢靠地安装在轴端上，可以保证两者的可靠性和传动稳定性。
具体地，如图3和图4所示，电机壳220形成有容置孔221，电机安装盖210和电机盖230形成有朝向电机壳220的容置槽211，定子240容置于容置孔221和两个容置槽211内。也就是说，定子240的中部容置于容置孔221内，定子240的两侧分别容置于对应的容置槽211内，这样可以有效容置定子240，可以保证定子240的安装可靠性，而且可以减小电机壳220的轴向尺寸。
可选地，容置孔221与定子240过盈配合。过盈配合的方式简单可靠，这样可以保证定子240在电机壳220内的安装可靠性。
根据本发明的一个具体实施例，如图5所示，电机安装盖210设置有第一限位部212，电机壳220的两侧设置有第二限位部222和第三限位部223，电机盖230设置有第四限位部231，第一限位部212与第二限位部222限位配合，第三限位部223和第四限位部231限位配合。第一限位部212和第二限位部222可以起到对电机安装盖210和电机壳220预限位的作用，可以降低发电机200的安装难度，可以提高电机安装盖210和电机壳220之间的安装可靠性。第三限位部223和第四限位部231可以起到对电机壳220和电机盖230预限位的作用，可以降低发电机200的安装难度，可以提高电机壳220和电机盖230之间的安装可靠性。
其中，如图5所示，第一限位部212和第二限位部222中的一个为外凸的限位环且另一个为内凹的限位槽，第三限位部223和第四限位部231中的一个为外凸的限位环且另一个为内凹的限位槽。例如，第一限位部212和第四限位部231均为限位环，第二限位部222和第三限位部223均为限位槽，这样至少一定程度上能够降低电机壳220的制造难度。通过限位槽和限位环的配合，可以提高发电机200的结构可靠性，以及可以降低发电机200的安装难度。
还有，结合图5和图11所示，电机安装盖210设置有第五限位部213，曲轴箱20设置有第六限位部27，第五限位部213与第六限位部27限位配合。第五限位部213和第六限位部27可以起到对电机安装盖210和曲轴箱20预限位的作用，可以降低发电机200的安装难度，以及可以提高电机安装盖210和曲轴箱20的安装可靠性。
其中，如图5和图11所示，第五限位部213和第六限位部27中的一个为外凸的限位环且另一个为内凹的限位槽。例如，第五限位部213可以为限位槽，第六限位部27可以为限位环。其中，电机安装盖210上可以设置有供曲轴10的轴端穿过的穿孔，该穿孔可以设置有轴承，限位环围绕轴承设置。
可选地，如图3和图4所示，定子240连接有出线端，电机盖230的一部分向远离电机壳220的方向凸出以形成容置出线端的容置空间，发电机200还包括：盒盖260，盒盖260盖设于容置空间处。由此，发电机200可以有效解决出线端的布置问题，而且仅需要增加盒盖260即可，从而可以简化发电机200的制造难度。盒盖260和电机盖230之间可以设置有密封垫。
具体地，如图4所示，电机壳220内形成有液冷通道，电机壳220还设置有连通液冷通道的进液口224和出液口225。也就是说，电机壳220内可以流动有冷却液，设置在冷却通道内的冷却液可以带走发电机200工作时产生的热量，从而可以有效降低发电机200的温度，可以使得发电机200的温度保持在合理的工作温度区间。
可选地，电机安装盖210可以拆卸地安装在曲轴箱20的一侧，电机壳220可以拆卸地安装在电机安装盖210的一侧，电机盖230可以拆卸地安装在电机壳220的一侧。可拆卸的方式可以采用紧固件固定连接。如此设置的发电机200结构简单，安装方便，从而可以降低发电机200的安装难度，以及可以便于后续的维修。
其中，如图4所示，发动机100还可以包括：缸体30和两个活塞连杆组40，缸体30设置于曲轴箱20的上部，缸体30具有两个气缸，两个活塞连杆组40的活塞分别设置于两个气缸内且连杆分别连接在曲轴10上。
下面结合附图详细描述一下根据本发明实施例的发动机100的曲轴箱20。
如图6、图7和图11所示，根据本发明实施例的曲轴箱20可以包括：第一箱体21、第二箱体22、油底壳23和边盖24，第二箱体22连接于第一箱体21的下方，第二箱体22和第一箱体21限定出曲轴腔和曲轴孔，曲轴腔与曲轴孔连通，曲轴孔形成于第一箱体21和第二箱体22的一端，油底壳23连接于第二箱体22的下方，边盖24连接于第一箱体21和第二箱体22的另一端。第一箱体21和第二箱体22上下配合，这样第一箱体21和第二箱体22可以限定出曲轴腔，曲轴10可以容置于曲轴腔内，而且曲轴10的轴端可以通过曲轴孔伸出曲轴腔，然后伸入发电机200内与转子250配合，其中，曲轴孔处可以设置有轴承或者轴瓦，这样可以保证曲轴10的转动稳定性。边盖24可以起到遮盖的作用，从而可以进一步地提高曲轴箱20的结构可靠性。
由此，根据本发明实施例的曲轴箱20，通过合理设置第一箱体21和第二箱体22，可以方便曲轴10伸出曲轴箱20与转子250配合，从而可以适用于混合动力总成1000，而且整体结构布置合理，结构可靠性高。
如图6和图7所示，第一箱体21的下侧形成有多个第一轴孔21a，第二箱体22的上侧形成有多个第二轴孔22a，多个第一轴孔21a与多个第二轴孔22a一一对应，以适于安装曲轴10。也就是说，第一箱体21的第一轴孔21a和第二箱体22的第二轴孔22a共同配合曲轴10，这样可以方便曲轴10的安装布置，而且可以降低第一箱体21和第二箱体22的布置难度。
进一步地，如图6和图7所示，第一箱体21的下侧形成有多个第三轴孔21b，第二箱体22的上侧形成有多个第四轴孔22b，多个第三轴孔21b与多个第四轴孔22b一一对应，以适于安装平衡轴。多个第三轴孔21b和多个第一轴孔21a在第一箱体21的下侧间隔设置，多个第二轴孔22a和多个第四轴孔22b在第二箱体22的上侧间隔设置，如此设置的第一箱体21和第二箱体22还可以容置平衡轴，平衡轴与曲轴10传动，平衡轴可以用于平衡活塞连杆组40运动时所产生的往复惯性力，从而可以提高发动机100的运行平顺性。
具体地，如图6和图7所示，第一轴孔21a、第二轴孔22a、第三轴孔21b和第四轴孔22b可以均为半圆孔。半圆孔易于设计制造，而且如此形状的轴孔易于支撑曲轴10和平衡轴，也可以便于轴承和轴瓦的安装布置。
可选地，第一轴孔21a、第二轴孔22a、第三轴孔21b和第四轴孔22b内部均设置有油槽。油槽内流动有润滑油，轴承或者轴瓦可以与油槽连通，这样润滑油可以有效润滑曲轴10和平衡轴的接触面，可以减少曲轴10和平衡轴的磨损，可以延长曲轴10和平衡轴的使用寿命，可以提高曲轴10和平衡轴的可靠性。
根据本发明的一个可选实施例，如图6所示，曲轴箱20还包括：第一箱盖25，第一箱盖25连接于第一箱体21的一侧，第一箱盖25与第一箱体21形成有第一容置腔。第一容置腔可以起到容置的作用，可以改变曲轴箱20的结构，可以使得曲轴箱20整体布局更加合理。
其中，如图6所示，相对于第一箱体21和第二箱体22的结合平面，第一箱盖25与第一箱体21的安装平面倾斜设置。如此设置的第一箱盖25可以有效适应第一箱体21的表面，可以保证其在第一箱体21表面的安装可靠性，第一箱盖25和第一箱体21之间可以采用紧固件固定连接。
进一步地，如图6所示，曲轴箱20还可以包括：第二箱盖26，第二箱盖26连接于第二箱体22的一侧，第二箱盖26与第二箱体22形成有第二容置腔，的第二容置腔与第一容置腔连通。第二容置腔可以起到容置的作用，可以改变曲轴箱20的结构，可以使得曲轴箱20整体布局更加合理。
其中，如图6和图11所示，相对于第一箱体21和第二箱体22的结合平面，第二箱盖26与第二箱体22的安装平面垂直设置。如此设置的第二箱盖26可以有效适应第二箱体22的表面，可以保证其在第二箱体22表面的安装可靠性，第二箱盖26和第二箱体22之间可以采用紧固件固定连接。
可选地，第一箱体21设置有至少两个通孔，两个通孔与曲轴腔相连通。两个通孔可以与缸体30的两个气缸相对应，也可以对于两个活塞连杆组40相对应，也就是说，如此设置的曲轴箱20可以适用于双缸发动机100，从而可以提升发动机100的动力性能，可以使得发电机200的发电效率高。
具体地，第一箱体21和第二箱体22中的至少一个在曲轴孔的一端设置有用于对发电机200限位的限位部。限位部即上述的第六限位部27，如此设置的第一箱体21和第二箱体22可以保证发电机200的安装可靠性。
下面再结合附图详细描述一下根据本发明实施例的曲轴箱20的油底壳23。
如图8-图10所示，根据本发明实施例的油底壳23可以包括：底壁23a和多个侧壁23b，多个侧壁23b连接在底壁23a的不同侧边上，而且多个侧壁23b在底壁23a的上方限定出敞开的油槽。可以理解的是，油槽用于容置润滑油，润滑发动机100运动副的润滑油在重力作用下向下流动，最终汇聚到油槽内，油槽内的润滑油还可以采用一定的方式向上供油，例如，供油方式可以为溅射方式，也可以为抽吸方式。其中，相邻的侧壁23b之间采用圆弧过渡。圆弧过渡可以使得油底壳23过渡自然，结构可靠性高，整体性好。
如图8所示，至少一个侧壁23b设置有用于避让传动轴300的避让区23c。也就是说，该油底壳23的底壁23a周围设置有传动轴300，避让区23c可以有效避让开传动轴300，可以给予传动轴300一定的容置空间，从而可以使得全地形车整体结构布局合理，而且至少一定程度上可以提高全地形车的最小离地距离，可以提升全地形车的通过性。
可选地，如图8和图9所示，避让区23c的表面可以为向油槽内部凹入的弧形表面。弧形表面可以有效避让传动轴300，而且可以降低油底壳23的制造难度，可以提高油底壳23的结构可靠性。
其中，如图8所示，两个相对的侧壁23b均设置有避让区23c。也就是说，油底壳23的左右两个侧壁23b均设置有避让区23c，两个传动轴300分别设置在油底壳23的两侧，如此设置的油底壳23整体布局合理，可以有效避开两个传动轴300，而且可以使得全地形车的整体布局合理。
可选地，如图9所示，每个侧壁23b均设置有从上端朝向底壁23a倾斜延伸的导油部23d。导油部23d可以为导油斜面，这样可以有利于润滑油向下流动至油底壳23的底部，可以提升油底壳23的汇聚润滑油的能力。
其中，如图9所示，每个侧壁23b的内表面形成有导油筋23e。导油筋23e可以为凸出的筋条，导油筋23e的设置一方面可以起到导油的作用，另一方面可以提高油底壳23的结构可靠性。
具体地，如图8和图9所示，底壁23a形成有放油孔，放油孔处设置有堵盖23f。在长时间未更换润滑油时，用户或者维修人员可以打开堵盖23f，放出润滑油，然后更换润滑油，从而可以方便润滑油的更换，可以有利于提升发动机100的性能。
可选地，如图8和图10所示，油底壳23的横截面积从开口向底部递减。也就是说，油底壳23构造为从上向下渐缩的结构，如此设置的油底壳23便于汇聚润滑油，可以可以便于润滑油再次润滑运动副。
其中，油底壳23为铝合金壳。铝合金壳结构强度高，重量轻，如此设置的油底壳23符合全地形车的轻量化设计目标。
