Description

教练车的副制动踏板装置及制动踏板总成
技术领域
本发明涉及一种教练车的副制动踏板装置, 以及具有该副制动踏板装置 的制动踏板总成。 背景技术
目前的教练车所采用的副制动踏板基本上都是简单的机械杠杆机构,例 如包括副踏板、 传动杆和连接端, 传动杆包括轴线基本成直角的第一杆部和 第二杆部, 连接端连接于第一杆部的末端, 副踏板连接于第二杆部的末端。 使用时,连接端连接到主制动踏板装置(例如主制动踏板装置的踏板臂)上。 当教练员踩下副制动踏板装置的副踏板时, 副制动踏板装置的连接端按下主 制动踏板装置的踏板臂, 使主制动踏板装置进行制动。 但是, 由于不同车型 的高度不统一, 或者即使同一车型的不同车辆的主制动踏板的高度也存在波 动, 这会导致副制动踏板装置的副踏板角度波动范围相当大, 使得教练员在 操作该副制动踏板装置时很不舒适, 而且还会影响副制动踏板装置的行程, 使得副制动踏板装置的制动力不足。 此外, 由于教练员的个体差异, 不同教 练员所需的副踏板角度和制动行程也不同, 而该现有的副制动踏板装置无法 根据不同教练员的需要进行调整。 发明内容
本发明所要解决的技术问题是,现有副制动踏板装置的无法适应不同主 制动踏板高度和教练员个体差异, 因此本发明的一个目的是提供一种能够针 对不同主制动踏板高度和教练员个体差异进行调整的副制动踏板装置。
为了解决上述技术问题, 一方面, 本发明实施方式提供了一种副制动踏 板装置, 该副制动踏板装置包括副踏板、 传动杆和连接端, 传动杆包括轴线 基本成直角的第一杆部和第二杆部, 连接端连接于第一杆部的末端, 副踏板 连接于第二杆部的末端, 其中, 副踏板的初始角度可调节。
另一方面, 本发明实施方式还提供了一种教练车的制动踏板总成, 该制 动踏板总成包括主制动踏板装置和上述教练车的副制动踏板装置。
通过本发明实施方式的上述技术方案, 由于副踏板的初始角度可调节, 因此能够通过调节副踏板的初始角度来适应不同主制动踏板的高度和教练 员个体差异。
本发明的其他特征和优点将在随后的具体实施方式部分予以详细说明。 附图说明
附图是用来提供对本发明的进一步理解, 并且构成说明书的一部分, 与 本发明的具体实施方式一起用于解释本发明, 但并不构成对本发明的限制。 在附图中:
图 1是根据本发明的一种实施方式的副制动踏板装置的结构示意图; 图 2是图 1中的 A部的局部放大分解示意图;
图 3是根据本发明的另一种实施方式的副制动踏板装置的结构示意图; 图 4是图 3中的 B部的局部放大分解示意图;
图 5是根据本发明的再一种实施方式的副制动踏板装置的结构示意图; 图 6是图 5中的 C部的局部放大分解示意图。 具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。 应当理解的是, 此处所描述的具体实施方式仅用于说明和解释本发明, 并不用于限制本发 明。 如图 1所示,本发明的一种实施方式提供的副制动踏板装置包括副踏板 1、 传动杆 2和连接端 3, 传动杆 2包括轴线基本成直角的第一杆部 21和第 二杆部 22, 连接端 3连接于第一杆部 21的末端, 副踏板 1连接于第二杆部 22的末端, 其中, 副踏板 1的初始角度 ct可调节。
副踏板 1的初始角度 α是指副制动踏板装置安装在车辆地板上的初始状 态下(即不对副踏板 1进行任何动作的状态下)副踏板 1与车辆地板形成的 角度。
使用时, 如图 1和图 3所示, 连接端 3连接在主制动踏板装置的踏板臂 4上。 由于副踏板 1的初始角度 α可调节, 因此能够通过调节副踏板 1的初 始角度 α来适应不同主制动踏板的高度和教练员个体差异。
副踏板 1 的初始角度 α可调节这一特性可以采用多种适当的结构来实 现, 例如, 可以采用具有可调节结构的传动杆 2来实现。 传动杆 2可以采用 各种适当的结构来通过不同的调节方式来实现上述目的。 例如, 作为一种具 体的实施方式, 第一杆部 21可以为长度可调式杆。 从而通过调节第一杆部 21的长度 L来实现对副踏板 1的初始角度 α和副制动踏板装置高度的调节。
第一杆部 21作为长度可调式杆也可以通过各种具体结构来实现, 例如 作为一种具体的实施方式, 如图 1和图 2所示, 第一杆部 21可以包括第一 部件 211、 第二部件 212和锁止螺钉 213, 第一部件 211具有长孔, 第二部 件 212具有可插入长孔的插入部, 并且长孔与插入部通过锁止螺钉 213进行 固定。 例如更具体地如图 2所示, 第一部件 211的长孔上形成有内螺紋(图 中未示出), 第二部件 212的插入部上形成有与该内螺紋配合的外螺紋 (图 中未示出), 通过螺紋啮合而使得第一部件 211相对于第二部件 212轴向固 定。 第一部件 211的长孔的侧壁上形成有长槽 214, 第二部件 212的插入部 上形成有凹孔 215, 锁止螺钉 213可以穿过长槽 214并锁止到凹孔 215内, 以使得第一部件 211相对于第二部件 212周向固定。 使用时, 首先调整副踏 板 1的初始角度 α到适当位置,然后通过调节第二部件 212的插入部插入第 一部件 211的长孔中的量, 来调节第一杆部 21的长度 L, 并用锁止螺钉 213 进行锁止, 从而能够适应不同的主踏板 4的高度。
根据本发明的另一种具体实施方式,作为实现可调式的传动杆 2的一种 方式, 第二杆部 22可以为角度可调式杆。 从而通过调节第一杆部 21的轴线 相对于第二杆部 22所安装的平面 (即车辆地板所在的平面) 的角度 β来实 现对副踏板 1的初始角度 α和副制动踏板装置高度的调节。
第二杆部 22作为角度可调式杆也可以通过各种具体结构来实现。
例如作为一种具体的实施方式, 如图 3和图 4所示, 第二杆部 22包括 第一螺紋管件 221、第二螺紋管件 222、螺紋接头 223 (该第一螺紋管件 221、 第二螺紋管件 222、 螺紋接头 223的螺紋在图中未示出) 和锁止螺母 224, 第一螺紋管件 221和第二螺紋管件 222通过螺紋接头 223相连接, 并通过锁 止螺母 224进行锁止。 使用时, 首先调整副踏板 1的角度 α到适当位置, 然 后通过调节第一螺紋管件 221相对于第二螺紋管件 222的角度(即使第一螺 紋管件 221相对于第二螺紋管件 222转动适当角度) 来调节第一杆部 21的 轴线相对于第二杆部 22所安装的平面的角度 β, 并通过锁止螺母 224进行 锁止, 从而实现对副踏板 1角度 α以及副制动踏板装置高度的调节。
例如作为另一种具体的实施方式, 如图 5和图 6所示, 第二杆部 22可 以包括相互配合的内花键部 225和外花键部 226以及将内花键部 225和外花 键部 226相互锁紧的锁止件 227。 使用时, 首先调整副踏板 1的角度 ct到适 当位置, 然后通过调节内花键部 225相对于外花键部 226的角度(即使外花 键部 226相对于内花键部 225转动适当的角度), 从而调节第一杆部 21的轴 线相对于第二杆部 22所安装的平面的角度 β, 然后通过锁止件 227使得内 花键部 225和外花键部 226相互锁紧, 从而实现对副踏板 1角度 α以及副制 动踏板装置高度的调节。 内花键部 225和外花键部 226之间的锁紧可以通过 各种适当的方式来实现, 例如如图 5和图 6所示, 内花键部 225的周壁上形 成有缺口 228, 该缺口 228的相对两侧分别形成有凸耳 229, 锁止件 227为 穿过凸耳 229进行紧固的螺栓。
当然,虽然上述长度可调式第一杆部 21和角度可调式第二杆部 22在不 同的实施方式中进行说明,但是显然传动杆 2可以同时具有上述长度可调式 第一杆部 21和角度可调式第二杆部 22, 从而为副制动踏板装置提供了更多 样化的调节方式。
此外, 连接端 3和第一杆部 21可以形成为一体, 也可以各自作为单独 的部件。 副踏板 1的具体结构及其与传动杆 2的连接方式为本领域所公知, 在此不再赘述。
另一方面, 本发明实施方式还提供了一种教练车的制动踏板总成, 该制 动踏板总成包括主制动踏板装置和上文所述的副制动踏板装置。
在该教练车的制动踏板总成中,副制动踏板装置的连接端 3连接到主踏 板装置的主踏板臂 4上。 这可以采用各种适当的连接方式来实现, 例如副制 动踏板装置的连接端 3可以直接搭靠在主制动踏板装置的主踏板臂 4上。当 教练员踩下副踏板 1时, 副踏板 1通过传动杆 2使得连接端 3按压主踏板臂 4, 从而使得主制动踏板装置进行制动; 当教练员松开副踏板 1 时, 副制动 踏板装置回复到初始位置, 连接端 3不再作用在主踏板臂 4上, 从而主制动 踏板装置也回复到初始位置。但是这种连接方式会使得连接端 3与主踏板臂 4之间在在动作过程中产生冲击, 进而影响整个制动踏板总成的制动效果。 因此优选地, 如图 3所示, 连接端 3通过挂簧 5连接到主制动踏板装置的踏 板臂 4上,从而可以减少连接端 3与主踏板臂 4之间在制动动作过程中产生 的冲击。
在教练车的制动踏板总成中, 副制动踏板装置的第二杆部 22通过固定 件固定到车辆的地板上, 该固定件可以采用各种适当的结构, 例如如图 1和 图 3所示, 该固定件可以包括套在第二杆部 22上的轴套 6和固定在轴套 6 上的固定板 7。通过将固定板 7固定到车辆的地板上来实现第二杆部 22可转 动地固定。
需要说明的是, 在上述具体实施方式中所描述的各个具体技术特征, 可 以通过任何合适的方式进行任意组合, 其同样落入本发明所公开的范围之 内。 另外, 本发明的各种不同的实施方式之间也可以进行任意组合, 只要其 不违背本发明的思想, 其同样应当视为本发明所公开的内容。
以上结合附图详细描述了本发明的优选实施方式, 但是, 本发明并不限 于上述实施方式中的具体细节, 在本发明的技术构思范围内, 可以对本发明 的技术方案进行多种简单变型, 这些简单变型均属于本发明的保护范围。
