本申请公开一种分布式电驱系统,减速装置与设置在两侧的第一驱动装置和第二驱动装置之间形成容置空间,由于控制器具有第一安装部,且该第一安装部与减速装置上下对应且位于第一驱动装置、第二驱动装置以及减速装置围成的容置空间内,一方面大大缩短控制器与第一驱动装置和第二驱动装置之间的高度差,尽可能降低分布式电驱系统高度尺寸,使其在有限的空间内更加紧凑。另一方面,便于驱动装置的电机三相线与控制器铜排直连,缩短连接路径和减少线缆的弯曲程度,从而起到提高信号传输效率,并减少故障点的作用,还大大节省了用铜量,可以减少对铜材料的需求,从而降低制造成本。
在本申请的一些实施例中,减速装置的相应两端为第一端和第二端,第一安装部的一端装设于容置空间内且与第一端对应设置,第一安装部的另一端的相对两侧上均设置有第二安装部,两个第二安装部位于第二端的相对两侧上。通过将控制器的第二安装部分布在减速装置第二端的相对两侧上,进而能充分利用减速装置第二端的输出端两侧的空间,能进一步降低分布式电驱系统构型的高度尺寸。
在本申请的一些实施例中,第一安装部以及两侧设置的第二安装部之间围合成凹槽,减速装置的第二端至少部分位于凹槽内。通过设置两第二安装部与第一安装部之间围成凹槽,从而增加了第二安装部沿第一驱动装置与第二驱动装置轴向方向上的尺寸,以使控制器容纳更多控制器元件,同时可以在不增加分布式电驱系统的高度尺寸的情况下,使减速装置与第二安装部在高度方向至少部分重合,以减小分布式电驱系统在高度方向的尺寸。
在本申请的一些实施例中,第一输入端和第二输入端对应地位于第一端的相对两侧,第二端的相对两侧对应设有第一输出端与第二输出端。这样,输入端与对应的第一驱动装置或者第二驱动装置连接而作为减速装置的动力来源,输出端对应地与其他传动装置连接而作为减速装置的动力输出端。
在本申请的一些实施例中,还包括第一输出轴和第二输出轴,第一输出轴用于连接第一输出端与车轮,第二输出轴用于连接第二输出端与车轮,其中一个第二安装部与第一输出轴上下对应,另一个第二安装部与第二输出轴上下对应。通过将第二安装部与第一输出轴或第二输出轴上下对应,两个第二安装部位于第二端的相对两侧且沿上下方向高于相应的第一输出端与第二输出端,这样,当分布式电驱系统应用在车辆中,不仅能充分利用第一输出轴与车辆底部之间的空间来安装控制器,能够更好地保护控制器,从而提高结构的稳定性。

在本申请的一些实施例中,减速器包括一级减速齿轮组和二级减速齿轮组,一级减速齿轮组位于减速装置的相应两端的其中一端上,二级减速齿轮组位于减速装置的相应两端的另外一端上,一级减速齿轮组的输出端与二级减速齿轮组的输入端传动连接且同轴设置。通过将一级减速齿轮组的输入端与二级减速齿轮组的输出端对应地设置在减速装置的相对应的两端上,能有效利用减速器沿车身长度方向的空间利用,一级减速齿轮组的输出端与二级减速齿轮组的输入端之间通过同轴传动连接从而缩短在沿车身长度方向的占用尺寸,使得分布式电驱系统的整体结构更加紧凑。
在本申请的一些实施例中,一级减速齿轮组设有第一输入端,二级减速齿轮组设有第一输出端,一级减速齿轮组相对于二级减速齿轮组更靠近第一驱动装置设置。进而可以降低二级减速齿轮组的输出端与第一驱动装置的壳体造成干涉,以降低驱动装置需向外侧移动避让导致轴向距离增大的情况发生。
在本申请的一些实施例中,还包括锁止机构,锁止机构连接于两个减速器之间,锁止机构通过接合两个减速器,以将其中一侧的减速的动力传递至另一侧的减速器上。通过锁止机构连接两个减速器,可以增加车辆的牵引力,在锁止机构结合两侧的减速器时,在一侧的减速器工作的情况下,锁止机构将动力传递至另一侧的减速器,使得两个减速器共同作用,提供更大的驱动力,有助于车辆克服障碍和脱困。

现有分布式电驱技术由于集成了双电机及双电控,而电机和控制器4的尺寸通常较大,还需要将每个驱动系统连接到车辆的底盘和车身上,导致包络尺寸较大,给整车的布置带来了困难。
基于此,本申请的一些实施例提出了一种分布式电驱系统,包括减速装置1、第一驱动装置2、第二驱动装置3以及控制器4。
请参照附图1至附图4,减速装置1的相对两侧对应设有第一输入端和第二输入端;第一驱动装置2和第二驱动装置3位于减速装置1的相对两侧,第一驱动装置2与第一输入端连接,第二驱动装置3与第二输入端连接,减速装置1、第一驱动装置2和第二驱动装置3之间围合成容置空间102,控制器4,具有第一安装部41,第一安装部41与减速装置1上下对应且位于第一驱动装置2和第二驱动装置3之间。
如附图2所示,第一驱动装置2和第二驱动装置3用于与减速装置1传动连接,在减速装置1作用下,能根据实际使用需求调节第一驱动装置2和第二驱动装置3的输出动力,控制器4用于与第一驱动装置2和第二驱动装置3电连接,从而控制第一驱动装置2和第二驱动装置3的工作状态。
其中,为了优化分布式电驱系统的空间构型设计,通过将第一驱动装置2和第二驱动装置3均相对于减速装置1向上凸起,这样设置使得减速装置1与设置在两侧的第一驱动装置2和第二驱动装置3之间形成容置空间102,由于控制器4具有第一安装部41,且该第一安装部41与减速装置1上下对应且位于第一驱动装置2和第二驱动装置3之间,使得第一安装部41可以安装于上述的容置空间102中,一方面大大缩短控制器4与第一驱动装置2和第二驱动装置3之间的高度差,尽可能降低分布式电驱系统高度尺寸,使其在有限的空间内更加紧凑。另一方面,第一驱动装置2和第二驱动装置3的高于减速装置1设置的空间布局,还有利于由第一驱动装置2和第二驱动装置3流向减速装置1的冷却油输送效率,从而提高分布式电驱系统在传动过程中的冷却效果,具有良好的散热性能从而有利于分布式电驱系统在各种工作条件下稳定运行,延长其使用寿命。
更详细地,该布局可以解决现有的分布式电驱系统构型中由于控制器4与驱动装置之间的高度差太大,从而增加连接的困难度,出现连接线分布杂乱等问题。而本申请设计的分布式电驱系统构型中,大大缩短了控制器4与第一驱动装置2和第二驱动装置3之间的高度尺寸,避免驱动装置的电机三相线需要绕过这个高度差,从而增加线的长度和弯曲程度,而长距离和过多的弯曲可能会增加线缆的电阻,影响信号的传输效果的问题。上述的分布式电驱系统中,便于驱动装置的电机三相线与控制器4铜排直连,缩短连接路径和减少线缆的弯曲程度,从而起到提高信号传输效率,并减少故障点的作用,还大大节省了用铜量,可以减少对铜材料的需求,从而降低制造成本。
在本申请的一些实施例中,减速装置1的相应两端为第一端和第二端,第一输入端和第二输入端对应地位于第一端的相对两侧,第二端的相对两侧对应设有第一输出端与第二输出端。减速装置1的第一端和第二端分别对应地配置为输入端以及输出端,其中,输入端与对应的第一驱动装置2或者第二驱动装置3连接而作为减速装置1的动力来源,输出端对应地与其他传动装置连接而作为减速装置1的动力输出端。
进一步地,第一安装部41的一端装设于容置空间102内且与第一端对应设置,具体地,如图2和图4所示,第一安装部41的一端与第一端上下对应且位于第一驱动装置2和第二驱动装置3之间,第一安装部41的另一端与第二端上下对应,控制器4还具有第二安装部42,第一安装部41的另一端的相对两侧上均设置有第二安装部42,两个第二安装部42位于第二端的相对两侧上。
具体来说,为了进一步降低分布式电驱系统构型的高度尺寸,可以通过进一步设计控制器4的分布结构从而充分利用减速装置1输出端一侧的空间,控制器4还包括设置在第一安装部41的另一端的相对两侧上的第二安装部42,这样,第二安装部42可以为其他辅助部件或连接线路提供额外的空间,第二安装部42分布在减速装置1第二端的相对两侧上,结合上述的实施例方案以及附图可知,第二安装部42与对应一侧的驱动装置排列设置,从而进一步降低分布式电驱系统的空间高度,提高了系统集成度。
在本申请的一些实施例中,第一安装部41可以设置为长条状的延伸部,第二安装部42可以设置为长条状的侧凸部,相应地,两个侧凸部位于延伸部的两侧。进一步地,延伸部可以与减速装置1的长度方向上下对应设置,这样可以更加充分地利用减速装置1沿长度设置的空间,而且,侧凸部可以对应地装设于减速装置1的第二端与第一驱动装置2之间,或装设于减速装置1的第二端与第一驱动装置2之间,进而能够更好地利用分布式电驱系统的空间。
详细地,可参照图1和图2,控制器4的整体形状呈T字型,即第一安装部41与第二安装部42构成T字型,第一安装部41与减速器11上下对应设置,而第一安装部41两侧的第二安装部42则分布在减速装置1的第二端的两个外侧,并与各自对应的第一驱动装置2和第二驱动装置3相对设置。
当然,本申请并不限定控制器4的形状为上述的T字型,还可以设计成凸字形、土字形等,只要包含上述的第一安装部41和第二安装部42的分布构型也属于本申请限定的方案之一。
在本申请的一些实施例中,第一安装部41以及两侧设置的第二安装部42之间围合成凹槽103,减速装置1的第二端至少部分位于凹槽103内。结合附图1所示,两个第二安装部42与第一安装部41之间围合成的凹槽103朝向减速装置1的第二端的所在一侧设置,这样可以增加第二安装部42沿第一驱动装置2或第二驱动装置3的高度方向上的尺寸,一方面可以使控制器4容纳更多控制器元件,另一方面,在不增加分布式电驱系统的高度尺寸的情况下,使减速装置1与第二安装部42在高度方向至少部分重合,以减小分布式电驱系统在高度方向的尺寸。
进一步地,分布式电驱系统还包括第一输出轴51和第二输出轴52,第一输出轴51用于连接第一输出端与车轮,第二输出轴52用于连接第二输出端与车轮,其中一个第二安装部42与第一输出轴51上下对应,另一个第二安装部42与第二输出轴52上下对应。
如附图5所示,附图标示的W1和W2分别指左右两侧的车轮,通过第一输出轴51和第二输出轴52将减速装置1的输出端与车轮连接,可以增强整个系统的输出稳定性。输出轴的设计可以确保动力传输更加直接和高效,减少能量损失和振动,而且通过将第二安装部42与第一输出轴51或第二输出轴52上下对应,两个第二安装部42位于第二端的相对两侧且沿上下方向高于相应的第一输出端与第二输出端,这样,当分布式电驱系统应用在车辆中,不仅能充分利用第一输出轴51与车辆底部之间的空间来安装控制器4,控制器4的第二安装部42与对应的第一驱动装置和第二驱动装置相对设置,从而有利于驱动装置的电机三相线与控制器铜排直连,大大节省了用铜量,还能够更好地保护控制器4,从而提高结构的稳定性。
如图2和图3所示,分布式电驱系统还包括第一电连接器71和第二电连接器72,对应地,第一电连接器71与第二电连接器72分别用于与第一驱动装置2和第二驱动装置3电控连接。其中,第一电连接器71位于第一驱动装置2的轴向中心线上方且与同侧设置的第二安装部42相对设置,第一电连接器71用于连接第一驱动装置2与前述同侧设置的第二安装部42,第二电连接器72位于第二驱动装置3的轴向中心线上方且与同侧设置的第二安装部42相对设置,第二电连接器72用于连接第二驱动装置3与前述同侧设置的第二安装部42。
举例而言,通过将第一电连接器71设置在第一驱动装置2的轴向中心线上方且与第二安装部42相对设置,使得第一驱动装置2与第二安装部42之间的电连接呈直连结构,避免其他连接需要增加线的长度和弯曲程度,从而增强电气稳定性。
同样地,第二驱动装置3与第二安装部42之间的电连接也呈直连结构,能缩短连接路径和减少线缆的弯曲程度,从而起到提高信号传输效率,并减少故障点的作用,还大大节省了用铜量。
更详细地,第一驱动装置2以及第二驱动装置3分别对应地设置有电机,对应地,第一驱动装置2以及第二驱动装置3分别通过转子转轴与减速装置1传动连接,第一驱动装置2的轴向中心线可以理解为转子转轴的轴心线;而电连接器7为高压连接器,控制器4与两侧的高压连接器之间设置密封圈密封,使其具备更好的防尘防水效果,提高电连接的安全性和稳定性。
其中,第一驱动装置2的轴向中心线上方且朝向第一电连接器71的一侧设有第一开口104,与第一驱动装置2位于同一侧的第二安装部42设有第二开口,第一开口104与第二开口相对设置,第一电连接器71的一侧通过第一开口104与第一驱动装置2连接,第一电连接器71的另一侧通过第二开口与同侧设置的第二安装部连接,这样,通过在第一驱动装置2以及第一驱动装置2对应设置的第二安装部42上设有对应的开口,使得第一电连接器71的两侧能通过开口连接第一驱动装置2以及对应一侧的第二安装部42,实现第一驱动装置2与控制器之间的直连结构。
同样地,第二驱动装置3的轴向中心线上方且朝向第二电连接器72的一侧设有第三开口,与第二驱动装置3位于同一侧的第二安装部42设有第四开口,第三开口与第四开口相对设置,第二电连接器72的一侧通过第三开口与第二驱动装置3连接,第二电连接器72的另一侧通过第四开口与同侧设置的第二安装部42连接,使得第二电连接器72的两侧能通过开口连接第二驱动装置3以及对应一侧的第二安装部42,实现第二驱动装置3与控制器之间的直连结构。
进一步地,如图3所示,减速装置1的相对两侧上对应地设置有一个减速器11,位于其中一侧的减速器11设有第一输入端,位于另一侧的减速器11设有第二输入端,两个减速器11呈中心对称设置或沿减速装置1的相对两侧平移设置。通过在减速装置1的相对两侧上设置两个减速器11,每个减速器11对应一个输入端,可以增加系统的驱动能力,从而提高系统的整体效率。更详细地,减速器11对应地设有上述的输入端以及输出端,输入端与对应侧的驱动装置传动连接,输出端可用于与车轮传动连接。进一步地,通过将两个减速器11呈中心对称设置或沿减速装置1的相对两侧平移设置,可以增强系统的稳定性,这种对称或平移的设计有助于平衡系统内的力和扭矩,减少振动和不平衡现象,提高系统的可靠性和稳定性,还可以更充分地利用空间,使整个系统更加紧凑和高效。
在本申请的一些实施例中,减速器包括一级减速齿轮组和二级减速齿轮组,一级减速齿轮组位于减速装置的相应两端的其中一端上,二级减速齿轮组位于减速装置的相应两端的另外一端上,一级减速齿轮组的输出端与二级减速齿轮组的输入端传动连接且同轴设置。
在本申请的一些实施例中,分布式电驱系统还包括锁止机构8,锁止机构8连接于两个减速器11之间,锁止机构8通过接合两个减速器11,以将其中一侧的减速的动力传递至另一侧的减速器11上。
具体而言,当车辆陷入泥泞、雪地或其他低附着力路面时,单个驱动装置以及减速器11可能无法提供足够的牵引力使车辆脱困,通过锁止机构8连接两个减速器11,可以增加车辆的牵引力,在锁止机构8结合两侧的减速器11时,在一侧的减速器11工作的情况下,锁止机构8将动力传递至另一侧的减速器11,使得两个减速器11共同作用,提供更大的驱动力,有助于车辆克服障碍和脱困。而且,在复杂路况下,车辆的动力传输可能会受到干扰或中断,可以通过锁止机构8中的设置确保两个减速器11之间的稳定连接,防止动力传输过程中的损失或中断,这种稳定性确保了持续、有效的动力输出,有助于提高车辆的脱困能力。
进一步地,还包括第一输入轴61和第二输入轴62,第一输入轴61传动连接于第一驱动装置2与对应一侧的减速器11之间,第二输入轴62传动连接于第二驱动装置3与对应一侧的减速器11之间,锁止机构8设置在第一输入轴61与第二输入轴62之间,以使锁止机构8处于接合状态下,将驱动一侧的减速器11的动力传递至另一侧的减速器11上。通过将第一驱动装置2和第二驱动装置3分别驱动对应一侧的减速器11,第一输入轴61和第二输入轴62分别用于动力传递,将第一驱动装置2和第二驱动装置3的动力传递给减速器11,而锁止机构8设置在第一输入轴61与第二输入轴62之间,能够实现两侧减速器11的动力同步传递。
通常地,当第一驱动装置2启动时,其动力通过第一输入轴61传递给对应一侧的减速器11,驱动减速器11工作,同样地,第二驱动装置3的动力通过第二输入轴62传递给另一侧的减速器11。请参照附图5,当需要将两侧减速器11的动力进行同步传递时,锁止机构8处于结合第一输入轴61与第二输入轴62的状态,此时第一输入轴61与第二输入轴62被连接在一起,实现了两侧减速器11的动力传递。当不需要两侧减速器11协同工作时,锁止机构8可以处于分离状态,使两侧减速器11独立工作,实现分布式驱动。这样可以更好地适应不同的工况和需求,提高系统的灵活性和效率。这样,能够提高车辆的牵引力和脱困能力,使其更好地适应复杂路况和恶劣环境,同时,系统的集成度和灵活性也得到了提高。
在本申请的一些实施例中,减速器11包括一级减速齿轮组111和二级减速齿轮组112,一级减速齿轮组111位于减速装置1的相应两端的其中一端上,二级减速齿轮组112位于减速装置1的相应两端的另外一端上,一级减速齿轮组111的输出端与二级减速齿轮组112的输入端传动连接且同轴设置。通过将一级减速齿轮组111的输入端与二级减速齿轮组112的输出端对应地设置在减速装置1的相对应的两端上,结合图3所示,减速装置1的相对应的两端也可以理解为减速装置1的长度方向,一级减速齿轮组111和二级减速齿轮组112沿减速装置1的长度方向分布,当该分布式电驱系统应用在车辆上时,能有效利用减速器11沿车身长度方向的空间利用,一级减速齿轮组111的输出端与二级减速齿轮组112的输入端之间通过同轴传动连接从而缩短在沿车身长度方向的占用尺寸,使得分布式电驱系统的整体结构更加紧凑。
以设有第一输入端的减速器11举例,一级减速齿轮组111设有第一输入端,二级减速齿轮组112设有第一输出端,一级减速齿轮组111相对于二级减速齿轮组112更靠近第一驱动装置设置。
需要说明的是,设有第二输入端的减速器11,其一级减速齿轮组111同样可以相对于其二级减速齿轮组112更靠近第二驱动装置设置。
具体地,两侧的减速器11的一级减速齿轮组111分别设置第一级传入齿轮,该齿轮直接与对应一侧的第一输入轴61或者第二输入轴62连接,从而在驱动装置的带动下进行动力传递。请参照附图3和图5,减速器11包括一级减速齿轮组111和二级减速齿轮组112,其中,一级减速齿轮组111包括相啮合的一级主动齿轮1111和一级从动齿轮1112,二级减速齿轮组112包括相啮合的二级主动齿轮1121和二级从动齿轮1122,第一输入轴61与一级主动齿轮1111相连接,一级从动齿轮1112与二级主动齿轮1121设置于同一个中间传动轴上,二级从动齿轮1122则通过第一输出轴51或第二输出轴52带动两侧的车轮转动。锁止机构8还可以设置在第一输出轴51和第二输出轴52之间,同样能起到将其中一侧的减速器11的动力传递至另一侧的减速器11上。但将锁止机构8设置在第一输入轴61与第二输入轴62之间,由于输入轴是动力传递的起始点,因此在此位置控制动力传递可以更加直接和高效,而且还能减少扭矩在传递过程中的损失,两侧减速器11的扭矩能够更加高效地传递,更加迅速、准确地实现两侧减速器11的动力同步,提高了车辆的牵引力和脱困能力。
更详细举例而言,为了进一步缩短分布式电驱系统的轴向尺寸,将一级主动齿轮1111靠近对应所在同一侧的第一驱动装置2或第二驱动装置3布置,从而有利于大幅减小第一驱动装置2与第二驱动装置3之间的轴向距离,另一方面,以靠近第一驱动装置2的减速器举例而言,二级减速齿轮组112相对于一级减速齿轮组111更加远离第一驱动装置2设置,这样可以避免二级减速齿轮组112的输出端与第一驱动装置2的壳体造成干涉,而使得驱动装置需向外侧移动避让导致轴向距离增大的情况发生。
进一步地,锁止机构8包括同步器。其中,同步器能够减小第一输入轴61与第二输入轴62之间的冲击和振动。在接合和分离过程中,同步器可以平滑地过渡,减少了对系统的冲击,降低了振动和噪音,提高了系统的舒适性和稳定性。
在本申请的一些实施例中,分布式电驱系统还包括油泵总成装置9,油泵总成装置9设置在第一安装部41的下方且位于第一驱动装置2和第二驱动装置3之间,第一驱动装置2和第二驱动装置3的顶部均相对于油泵总成装置9的顶部向上凸起,油泵总成装置9用于向第一驱动装置2和第二驱动装置3输送冷却油。本申请的分布式电驱系统中,通过将电动油泵子总成设计为独立结构,并集成设计成油泵总成装置9,油泵总成装置9用于向第一驱动装置2和第二驱动装置3输送冷却油,从而能够确保第一驱动装置2和第二驱动装置3在适当的温度下工作,避免过热导致的故障或安全隐患。具体来说,油泵总成装置9装设于第一驱动装置2和第二驱动装置3之间,缩短了油泵总成装置9向两侧输送冷却油的油道路径,而且油泵总成装置9集成设置在控制器4的第一安装部41下方,有利于减少分布式电驱系统的高度,而且,独立设计的电动油泵子总成可以更加灵活地适应不同的空间布局需求,可以根据具体的车辆设计和电驱系统的配置,电动油泵子总成放置在更加合适的位置,从而优化整个系统的布局,提高车辆的性能和效率。
详细地,请参照附图6,油泵总成装置9包括电动油泵电机91、泵头92和电动油泵壳体93,其中,电动油泵壳体93设有安装腔体,使得电动油泵电机91和泵头92能集成安装于安装腔体内,电动油泵壳体93起到保护的作用。进一步地,油泵总成装置9与两侧的第一驱动装置2和第二驱动装置3之间采用螺栓连接,其拆卸和更换过程相对简单。当电动油泵出现故障或需要更换时,可以快速地将其从螺栓连接处拆下并进行更换,而无需对整个电驱系统进行深入的拆卸。这大大提高了维修效率和便利性。
进一步地,减速装置1的外部设有减速器壳体12,减速器壳体12的部分凹设形成安装槽101,油泵总成装置9安装于安装槽101内。通过将减速器壳体12的凹设形成安装槽101从而能够容纳油泵总成装置9,一方面能更加充分利用减速器11、控制器4的第一安装部41、第一驱动装置2以及第二驱动装置3之间的空间,进一步优化系统的整体尺寸;另一方面,油泵总成装置9安装于安装槽101内,可以增强油泵总成装置9的稳定性,防止其在工作过程中发生位移或振动。
在本申请的一些实施例中,分布式电驱系统还包括传感器装置,传感器装置与第一驱动装置2和第二驱动装置3电连接,用于感应获取第一驱动装置2和第二驱动装置3的工作状态参数,传感器装置设置在减速装置1的上方,传感器装置与减速装置1上下对应且位于第一驱动装置2和第二驱动装置3之间。
其中,传感器装置用于感应获取第一驱动装置2和第二驱动装置3的工作状态参数,如转速、温度、压力等,这种实时监测功能有助于及时发现异常情况,并采取相应的措施进行应对。相比于现有技术而言,将传感器装置集成在第一驱动装置2和第二驱动装置3之间的区域内,能够最大限度地利用有限的空间,从而减少第一驱动装置2和第二驱动装置3的轴向尺寸,应用在车辆中,相应地可以减少分布式电驱系统沿车宽方向的尺寸。
更详细举例而言,传感器装置包括旋变信号传感器和油温信号传感器,其中旋变信号传感器通常用于检测电机的转子位置,有利于精确控制电机的旋转角度和速度;油温信号传感器用于监测油温,确保系统在适宜的温度下工作,防止过热或损坏。将上述的传感器集成在第一驱动装置2和第二驱动装置3之间的区域,有效利用了这一空间,避免了在第一驱动装置2和第二驱动装置3的端盖侧集成所带来的额外尺寸增加,通过这种集成方式,可以减少分布式电驱系统的轴向尺寸,使其更加紧凑。
在本申请的一些实施例中,第一驱动装置2和第二驱动装置3的电连接线集成安装于第一驱动装置2和第二驱动装置3之间。详细地,第一驱动装置2和第二驱动装置3包括电机,电机与控制器4或者是其他装置的电连接线集成在它们之间的区域内,相比于现有技术中,将电连接线分散在电机端盖两侧的技术方案而言,能够很好地减少分布式电驱系统的轴向尺寸,使得整个系统更加紧凑;还能减少了电连接线的长度和复杂性,降低了因线路过长或过于复杂而产生的信号衰减、干扰和故障风险。
在本申请的一些实施例中,控制器4包括控制器壳体,控制器壳体呈T字型。
具体地,控制器壳体与控制器4的整体形状对应设置,其中,控制器壳体T字型中的第一安装部41与控制器4的第一安装部41对应,并对应设置在减速器11上方以及第一驱动装置2和第二驱动装置3之间,控制器壳体T字型中的两侧凸起部与控制器4的第二安装部42对应,结合上述的结构设置,控制器壳体呈T字型对应地装设于两驱动装置与减速装置1形成的容纳空间,以及减速装置1输出端的两侧之间,可使整体结构紧凑,另一方面可缩短控制器壳体与第一驱动装置2及第二驱动装置3之间的高度差,从而便于电机三相线与控制器4铜排直连,缩短连接路径,节省用铜量。
本申请的一些实施例提出了一种车辆,包括车体、车轮以及电驱系统,车轮装设于车体上,电驱系统包括如上述任一实施例的分布式电驱系统,分布式电驱系统用于驱动两个车轮运动。通过采用上述任一实施例的分布式电驱系统,将第一驱动装置2和第二驱动装置3之间形成高度差设计,减速装置1安装于第一驱动装置2和第二驱动装置3之间,并且充分利用第一驱动装置2、第二驱动装置3以及减速装置1之间的空间而有效地降低电驱系统的高度尺寸,进一步地,具体结合对应的结构设计充分利用第一驱动装置2与第二驱动装置3之间的空间,从而有效降低电驱系统的轴向尺寸。
