Abstract

一种双离合器变速器,采用了两根输入轴(1,2)和两根驱动轴(3,18),实现了七个前进档(D1,D2,D3,D4,D5,D6,D7)和一个倒档(R),省去了为倒档(R)单独设置的倒档轴;采用八个同步器(S1,S2,S3,S4)控制了七个前进档(D1,D2,D3,D4,D5,D6,D7)和一个倒档(R)共八个档位的切换,部分档位共用主动齿轮,减少了总零件数量和变速器的轴向长度;由于低速档的从动齿轮(14,15,16)直径相对较大,根据结构布置需要将相应同步器(S2,S3)的结合套布置在所述从动齿轮(14,15,16)内侧,极大的节省了轴向空间;省去了一根倒档轴及其上的齿轮,节省的空间便于换档拨叉机构的布置,由于换档拨叉的支撑点没有了倒档轴及其上齿轮的阻碍,可以布置在与驱动轴(3,18)中心和换档执行机构靠近的位置,有利于拨叉机构的受力。

Description

一种双离合器变速器 技术领域
本发明属于汽车构造的技术领域, 涉及汽车的动力系统的结构, 更具体地说, 本 发明涉及一种双离合器变速器。 背景技术
双离合器变速器采用双离合系统和常规的定轴齿轮传动, 传动效率高, 换档时, 系统动力中断时间短, 有良好驾驶舒适性和燃油经济性。 自从大众公司成功装车上市 以来, 逐步成为变速箱行业发展的热点。
中国专利 CN 102084153A公开了一种双离合器变速器, 其具有两根输入轴, 输入 轴分别与第一离合器或第二离合器相连。 在输入轴的上方和下方设置了两根驱动轴, 驱动轴通过驱动轴上的驱动齿轮将扭矩传到差速器上。 为了实现倒车档, 又设置了另 一根轴, 其布置在第二驱动轴的上方; 此处的倒档如下实现: 即第一输入轴的扭矩通 过相应的齿轮副传递到用于倒车档的轴上, 然后由此通过倒车档齿轮传递到第二驱动 轴, 最后扭矩由此通过驱动轴的驱动齿轮作用到差速器上。 该双离合器变速器为倒档 单独设置一根轴的布置方式, 会使变速箱的换档机构布置及整体结构布置受到非常大 的限制, 妨碍了实现紧凑的结构形式。

下面对照附图, 通过对实施例的描述, 对本发明的具体实施方式作进一步详细的 说明, 以帮助本领域的技术人员对本发明的发明构思、 技术方案有更完整、 准确和深 入的理解。
如各附图所表达的本发明的结构, 为双离合器变速器, 包括输入部分、 驱动部分 和输出部分;
所述的输入部分包括同轴布置的第一输入轴 1和第二输入轴 2; 所述的第一输入 轴 1与第一离合器 K1连接, 第二输入轴 2与第二离合器 K2连接;
所述的第二输入轴 2为空心轴, 套在第一输入轴 1的外侧;
所述的驱动部分包括第一驱动轴 18和第二驱动轴 3 ;
所述的输出部分包括差速器 20,其上的主减速从动齿轮 20a分别与第一驱动轴 18 上的第一驱动轴主减速主动齿轮 19和第二驱动轴 3上的第二驱动轴主减速主动齿轮 4 啮合; 各轴相互平行布置。 且为水平布置。
所述的双离合器变速器设有七个前进档和一个倒档 R, 七个前进档分别为一档 Dl、 二档 D2、 三档 D3、 四档 D4、 五档 D5、 六档 D6和七档 D7。
本发明提供的七速双离合器变速器, 是一种紧凑型七速双离合器变速器, 该双离 合器变速器具有下列优点:
1、 采用两根输入轴和两根驱动轴实现了七个前进档和一个倒档, 省去了一根倒 档轴, 同时, 将一档从动齿轮、 二档从动齿轮设置在一根拥有相对较少齿数的主减速 主动齿轮的驱动轴上, 将六档从动齿轮, 七档从动齿轮设置在另外一根拥有相对较多 齿数的主减速主动齿轮的驱动轴, 实现了各齿轮尺寸和各档传动比的优化配置。 因此, 该布置结构紧凑、 简单合理, 齿轮、 轴及同步器零件数量少。
2、 由于一二三档的从动齿轮直径相对较大, 因此, 这些档位的同步器结合套可 以布置在齿轮内侧, 结合各档位位置的合理排布, 可以极大的节省轴向空间。
3、 由于省去了一根倒档轴, 其节省的空间便于换档拨叉机构的布置。
众所周知, 变速器的低速档通常是一档和二档, 其需要设置很大的总传动比, 变 速器的高速档通常是最高档和次高档, 其需要设置较小的总传动比, 变速器的各档的 总传动比为各档的齿轮副的传动比与主减速比 (即主减速从动齿轮的齿数与主减速主 动齿轮齿数的商) 的乘积。
本发明的双离合器变速器有两个驱动轴, 即拥有两个主减速比, 通常这两个主减 速比为不同数值, 将低速档搭配数值相对较大的主减速比、 高速档搭配相数值对较小 的主减速比的好处是, 可以减小各档的一对啮合齿轮直径的尺寸差, 齿轮的受力变得 相对均衡。
因此, 本发明将一档从动齿轮、 二档从动齿轮设置在一根拥有相对较少齿数的主 减速主动齿轮的第一驱动轴上, 将六档从动齿轮、 七档从动齿轮设置在另外一根拥有 相对较多齿数的主减速主动齿轮的第二驱动轴, 这样的布置方式, 实现了各齿轮尺寸 和各档传动比的优化配置。
本发明的总体构思是:
各档位的主动齿轮分别与第一输入轴或第二输入轴无相对转动的连接, 其中若干 个主动齿轮同时作为两个档位的主动齿轮, 各档位的从动齿轮空套在第一驱动轴或第 二驱动轴上, 通过同步装置实现从动齿轮与两驱动轴互联以实现各个档位。
利用设置在其中一根驱动轴上的一档从动齿轮作为倒档惰轮来实现倒档的换向; 其中, 一档从档齿轮布置在其中一根驱动轴上, 倒档从动齿轮布置在另外一根驱动轴 上, 一档所在的驱动轴的主减速主动齿轮的齿数少于倒档从动齿轮所在驱动轴的主减 速主动齿轮的齿数; 一档从动齿轮为塔齿轮, 具有一个第一齿轮和一个第二齿轮, 第 一齿轮的直径大于第二齿轮的直径; 其中, 第一齿轮与一档从动齿轮啮合, 第二齿轮 与倒档从动齿轮啮合, 从而实现倒档换向; 其中, 通过设置一档从档齿轮上的第二齿 轮齿数和倒档从动齿轮的齿数, 可以获得的较理想的倒档速比; 其中, 倒档从动齿轮 与偶数档 (例如六档) 从动齿轮设置在同一根驱动轴上并共用一个同步器。

所述的五七档同步器 S 1位于五档从动齿轮 8和七档从动齿轮 7之间, 六倒档同 步器 S4位于六档从动齿轮 5和倒档从动齿轮 6之间;
所述的五档从动齿轮 8位于远离双离合器的变速器后侧, 六档从动齿轮 5位于靠 近双离合器的变速器前侧。

第一输入轴 1、 第二输入轴 2、 第一驱动轴 18和第二驱动轴 3的上述空间配置在 图 2中示出。 图 2为图 1的右视图, 为了更好的理解转动部件的转动轴之间的空间位 置关系, 在图 2中有意的没有示出图 1中示出的一些齿轮。

2、 驱动轴上依次布置三档从动齿轮、 一档从动齿轮、 二档从动齿轮和四档从动 齿轮, 还固定有一三档同步器和二四档同步器, 一三档同步器位于一档从动齿轮和三 档从动齿轮之间, 二四档同步器位于二档从动齿轮和四档从动齿轮之间; 第二驱动轴 上依次布置五档从动齿轮、 七档从动齿轮、 倒档从动齿轮和六档从动齿轮, 还固定有 五七档同步器和六倒档同步器,五七档同步器位于五档从动齿轮和七档从动齿轮之间, 六倒档同步器位于六档从动齿轮和倒档从动齿轮之间。

1、 第一输入轴上依次固定五七档主动齿轮、 三档主动齿轮和一档主动齿轮; 第 二输入轴上依次固定二档主动齿轮和四六档主动齿轮。
奇数档和偶数档的主动齿轮分别布置在两根输入轴上, 换档时两根输入轴交替传 递动力, 保证换档过程中的动力不中断。
2、 第一驱动轴上依次布置五档从动齿轮、 一档从动齿轮、 二档从动齿轮和四档 从动齿轮, 还固定有一五档同步器和二四档同步器, 一五档同步器位于一档从动齿轮 和五档从动齿轮之间, 二四档同步器位于二档从动齿轮和四档从动齿轮之间; 第二驱 动轴上依次布置七档从动齿轮、 三档从动齿轮、 倒档从动齿轮和六档从动齿轮, 还固 定有三七档同步器和六倒档同步器, 三七档同步器位于三档从动齿轮和七档从动齿轮 之间, 六倒档同步器位于六档从动齿轮和倒档从动齿轮之间。
各档从动齿轮通过轴承安装在各驱动轴上, 倒档从动齿轮与形状为塔齿轮的一档 从动齿轮第二齿轮啮合, 其它档位的从动齿轮分别与对应的主动齿轮啮合, 且各档齿 轮副基本位于各同一平面内。 当需要进行换档时, 将相应档位的从动齿轮与驱动轴通 过同步器互联, 完成驱动轴与该档位从动齿轮的同步转动, 从而实现换档。
综上所述, 本发明的双离合器变速器采用了两根输入轴和两根驱动轴, 实现了七 个前进档和一个倒档, 省去了背景技术中所述双离合器变速器为倒档单独设置的倒档 轴。
本发明采用了八个同步器控制了七个前进档和一个倒档共八个档位的切换, 部分 档位共用主动齿轮, 因此, 减少了总零件数量和变速器的轴向长度。
本发明利用一二三档的从动齿轮相对直径较大, 可以根据结构布置需要将相应同 步器的结合套布置在这些齿轮内侧, 极大的节省轴向空间。
本发明由于省去了一根倒档轴及其上的齿轮, 其节省的空间便于换档拨叉机构的 布置, 这样, 换档拨叉的支撑点由于没有了倒档轴及其上齿轮的阻碍, 因此可以布置 在与驱动轴中心和换档执行机构靠近的位置, 这样的布置有利于拨叉机构的受力。
上面结合附图对本发明进行了示例性描述, 显然本发明具体实现并不受上述方式 的限制, 只要采用了本发明的方法构思和技术方案进行的各种非实质性的改进, 或未 经改进将本发明的构思和技术方案直接应用于其它场合的, 均在本发明的保护范围之 内。
