Description

自激制动钳
技术领域
本发明涉及一种自激制动钳(Self-energizing Brake Caliper)。
背景技术
在液压式制动系统中,在驾驶者踩踏制动踏板的情况下,在主气缸发生的压力通过盘式制动钳或鼓式制动器轮缸(wheel cylinder)而变换为制动力。包括自激制动器(self-energizing brake)作为增强该制动力的设备,例如,美国专利第5,012,901号公开的利用球(ball)或斜坡(ramp)的自激制动器、美国专利第6,318,513号公开的利用楔效应(wedge effect)的自激制动器。
但现有的自激制动器因结构复杂,而量产性低且制造成本高,在利用楔(wedge)的结构中,因插入现象而发生的自锁(self-locking)等各种理由而自激制动器实际无法适用于车辆。
并且,在线控制动(Brake-by-wire)中,在使用通过电动机驱动的EMB(机电制动,electro-mechanical brake)钳时,为了将其使用于需要大的制动力的前轮用盘式制动器,需要极大增大因电动机的驱动而产生的制动力。

第一插槽43被提供至内侧制动器板的上侧与下侧,第二插槽53被提供至外侧制动器板的上侧与下侧。
在制动时,接收所传输的驱动力,以使第一钳臂20与第二钳臂30的内侧端部22、32相互远离。
钳支架10包括:安装面18;贯通孔19,与安装面18邻接形成。第一钳臂20在安装面18的上部与钳支架10连接,第二钳臂30与钳支架10连接,以使在安装面18的下部经过贯通孔19。
驱动装置100的驱动力作用点与旋转轴12之间的第一距离大于第一钳臂20的外侧端部21与旋转轴12之间的第二距离。第一距离为制动器盘的旋转轴方向的距离,第二距离为制动器板的长度方向的距离。
发明的效果
本发明通过杠杆效应,按压制动器板的力与驱动装置的驱动力相比,进行第一次增大,在制动器板的摩擦材料中发生的摩擦力产生将钳臂向制动器盘侧旋转的力矩,第二次增加施加至制动器板的垂直力,由此,增加制动力强化效果。

第一钳臂20包括:外侧端部21、内侧端部22、第一安装孔23。外侧端部21固定于外侧制动器板50的第二端部52。安装螺栓8贯通外侧端部21的安装孔、形成于外侧制动器板50的第二端部52的安装孔,从而,联结外侧端部21与第二端部52。在安装螺栓8的端部通过联结销90,而防止安装螺栓8的滑脱。在需要比联结销更强的联结的情况下,也能够将槽顶螺母(castle nut)与安装螺栓8的端部联结,以代替联结销90。

制动器驱动装置100在发生驱动力(F0),以用于制动的情况下,以第一钳臂20与第二钳臂30相互远离的方式推动。但第一钳臂20与第二钳臂30以对于旋转轴12而能够旋转的方式与钳支架10联结,由此,第一钳臂20对于旋转轴12以逆时针方向旋转,第二钳臂30相对于旋转轴12而以顺时针方向旋转。第一导件60沿着第一插槽43滑动,第二导件70沿着第二插槽53滑动。
此时,第一插槽43与摩擦材料45的摩擦面平行,第二插槽53与摩擦材料55的摩擦面平行提供,由此,在钳臂20、30进行剪刀运动期间,摩擦材料45、55保持相互平行的状态。
第一钳臂20的外侧端部21固定于外侧制动器板50的第二端部52,通过第一钳臂20的旋转,而增加外侧制动器板50按压制动器盘1的力。因此,按压外侧制动器板50的力,通过杠杆效应,为F0的a/c倍。即以大于驱动装置100所产生的力的力,按压制动器盘1,由此,具有增加制动力效果。并且,第二钳臂30在内侧固定于内侧制动器板40的第二端部42,也具有同样的增加制动力的效果。
并且,在内侧制动器板40与外侧制动器板50按压制动器盘1的情况下,通过制动器盘1的旋转而产生摩擦力Ff,该摩擦力Ff产生将第一钳臂20与第二钳臂30向制动器盘1侧旋转的力矩。通过该旋转力矩,内侧及外侧制动器盘板40、50按压制动器盘1的力(Fp)增加,从而,极大化磁化效果。
从外侧观察制动器盘时,在以逆时针方向旋转的情况下,即车辆后退的情况下,在内侧及外侧制动器板40、50的摩擦材料45、55产生的摩擦力Ff的方向相反,而发生制动力低下(deenergizing)的效果。但在该情况下,因通过杠杆效应而产生的制动力强化效果相同,由此,制动力强化的效果比前进的情况小,但在现有技术的后退时,制动力更优秀。并且,在车辆的后退时,因以较低的速度移动,与前进方向相比,即使制动力强化效果低,实际适用时完全不存在问题。
在松开(release)制动器时,制动器驱动装置100的力向驱动力(F0)的相反方向产生,由此,以相互接近的方式拉拽第一钳臂20与第二钳臂30。此时,钳臂20、30通过剪刀运动而将内侧制动器板40与外侧制动器板50由制动器盘1远离,因此,内侧及外侧制动器板40、50按压制动器盘1的力(Fp)消失。
由此,在本发明中,因制动时自激(self-energizing)效应及松开制动器(release)通过引起剪刀运动的联动装置(linkage)而发生,由此,未发生因在利用楔(wedge)的结构中显示的插入而产生的自锁现象(self-locking)。
综上,参照附图对本发明进行了说明,但本发明的权利范围根据权利要求书确定,并非以上述实施例及/或附图所限制的进行解释。并且,权利要求书中记载的发明的、本领域明了的改良、变更及修正也应明确理解为包含于本发明的权利要求范围内。例如,本发明的自激钳结构在不脱离本发明的技术思想的状态下,也能够以适合鼓式制动器(drumbrake)的方式修正而适用。
