Description
本发明涉及变速器技术领域,具体涉及一种智能化自适应自动变速器。
现有的电动交通工具由于其传动结构的限制,在行驶过程中,完全由驾驶员在不能准确知晓行驶阻力的情况下,依据经验进行操控,因此,常常不可避免地出现电机工作状态与交通工具实际行驶状况不匹配的情况,造成电机堵转。尤其是交通工具处于启动、爬坡、逆风等低速重载条件时,现有的自动变速器不能实时检测阻力矩,造成电机往往需要在低效率、低转速、高扭矩情况下工作,而不能根据实际情况对电机的转速和扭矩进行适应性的调节,容易引起电机的意外损坏,增加维修和更换成本,同时也会直接影响到电池的续航里程。对于诸如电动物流车等对经济性要求较高的车型而言,传统的变速传动结构显然不能较好的满足其使用要求。并且,电动交通工具惯性滑动时,由于现有自动变速器结构设计的问题,变速器不能将车轮的扭力传递给电机,从而无法实现能力回收和储存,导致续航里程不理想。同时,现有电动交通的前进和倒退通过电机的正反转切换实现,导致倒挡速比较小,扭矩不足,不能适应于一些特殊状况。

一、前进挡:双向啮合花键套31与主轴1结合,与倒挡三级从动齿轮32分离;第二啮合花件套33与一级减速从动齿轮16结合。
本实施例中,弹性元件组12通过各端面轴承15施加压力,压紧摩擦离合器11的各外摩擦片11c和内摩擦片11d,此时摩擦离合器11在弹性元件组12的压力下处于结合状态,动力处于高速挡动力传递路线:
电机→动力输入轴22→前进挡一级主动齿轮23→前进挡一级从动齿轮轴19→传动传感凸轮套21→前进挡二级主动齿轮20→前进挡输入双联齿轮26 →外片花键套11b→摩擦片支撑盘11a→外摩擦片11c和内摩擦片11d→内片螺旋滚道套13→主轴1→双向啮合花键套31→主轴加长轴1a输出动力。
此时,多排组合式超越离合器3处于超越状态,弹性元件组12未被压缩。当主轴1传递给摩擦离合器11的阻力矩大于等于摩擦离合器11的预设载荷极限时,内片螺旋滚道套13与主轴1出现转速差,内片螺旋滚道套13朝压缩弹性元件组12移动,压缩弹性元件组12,摩擦离合器11的各外摩擦片11c和内摩擦片11d之间出现间隙,即分离,动力改为通过下述路线传递,即低速挡动力传递路线:
电机→动力输入轴22→前进挡一级主动齿轮23→前进挡一级从动齿轮轴19→传动传感凸轮套21→前进挡二级主动齿轮20→前进挡输入双联齿轮26→外片花键套11b→摩擦片支撑盘11a→一级减速主动齿轮18→一级减速从动齿轮16→第二啮合花件套33→副轴21→二级主动齿轮17→多排组合式超越离合器3→内心轮套2→内片螺旋滚道套13→主轴1→双向啮合花键套31→主轴加长轴1a输出动力。
此时,多排组合式超越离合器3未超越,弹性元件组12被压缩。从上述传递路线可以看出,本发明在运行时,形成一个保持一定压力的自动变速机构。
本实施例以电动汽车为例,整车在启动时阻力大于驱动力,阻力迫使主轴1相对内片螺旋滚道套13转动一定角度,在螺旋传动副的作用下,内片螺旋滚道套13通过端面轴承15压缩弹性元件组12,外摩擦片11c和内摩擦片11d分离,即摩擦离合器11处于断开状态,以低速挡速度转动;因此,自动实现了低速挡起动,缩短了起动时间。与此同时,弹性元件组12吸收运动阻力矩能量,为恢复高速挡挡位传递动力储备势能。
启动成功后,行驶阻力减少,当分力减少到小于弹性元件组12所产生的压力时,因被运动阻力压缩而产生弹性元件组12压力迅速释放的推动下,摩擦离合器11的各外摩擦片11c和内摩擦片11d恢复紧密贴合状态,以高速挡速度转动。
行驶过程中,随着运动阻力的变化自动换挡原理同上,在不需要切断动 力的情况下实现变挡,使整车运行平稳,安全低耗,而且传递路线简单化,提高传动效率。
二、倒挡:双向啮合花键套31与倒挡三级从动齿轮32结合,与主轴1分离;第二啮合花件套33与一级减速从动齿轮16分离。
倒挡动力传递路线:电机→动力输入轴22→倒挡一级从动齿轮29→倒挡一级齿轮轴27→倒挡二级从动齿轮30→倒挡二级齿轮轴28→倒挡三级从动齿轮32→双向啮合花键套31→主轴加长轴1a输出动力。
最后需要说明的是,上述描述仅仅为本发明的优选实施例,本领域的普通技术人员在本发明的启示下,在不违背本发明宗旨及权利要求的前提下,可以做出多种类似的表示,这样的变换均落入本发明的保护范围之内。
