Description

车高调整装置
技术领域
本发明涉及车高调整装置。更详细地说,涉及一种利用马达和齿轮而调整车高的车高调整装置。
背景技术
一般地说,悬架装置具备减震器和悬架弹簧,从而能够在行驶时吸收从路面传达的各种振动或冲击而提高乘车感。这种悬架装置的悬架弹簧可分为片弹簧、线圈悬架弹簧及空气弹簧(Air suspension)等,其中空气弹簧具有能够维持或调整车辆的高度的优点,但额外需要根据负荷调整空气量的装置及用于压缩空气的装置,因此其使用范围限定于公交车等大型车辆或高级轿车。
尤其,高级车辆中,为了提高乘车感及驾驶稳定性、燃油效率而利用调整车体高度的系统。具有代表性的方法是:空气弹簧,代替现有的线圈悬架弹簧而安装空气悬架弹簧并通过空气悬架弹簧的空气进出而调整车体高度的空气弹簧及;奔驰的ABC(Active Body Control-主动车身控制系统)系统,利用液压调整线圈悬架弹簧安装面的高度。
与所述空气悬架相关的传统技术为韩国专利公开公报第10-2010-0127395号(2010.12.06)即‘容易调整车高的混合空气悬架'。
所述容易调整车高的混合空气弹簧连接车体与车轮之间,根据空气的进出而调整车体的缓冲及车高。
所述ABC系统需考虑专用液压致动器、液压排管等,因此单价非常高,系统结构也复杂。
并且,空气悬架因利用空气,比液压更环保,系统结构也比较简单,但为了控制气压,各拐角需连接气压线路,个别空气悬架弹簧需要空气压缩器,以控制电磁气压阀并生成高压空气。
因此,空气悬架的系统单价也比车辆的其他系统高,目前主要用于高级车辆。
发明内容
(要解决的技术问题)
本发明的目的在于,为解决所述传统技术的问题点而提供一种车高调整装置,利用马达及齿轮而调整车辆的车高。
(解决问题的手段)
为达成所述目的的本发明的车高调整装置设置在用于支撑车辆负荷的悬架弹簧的上端部或支撑所述悬架弹簧与所述悬架弹簧的悬架支撑部之间,从而调整车高(vehicle-height),包括:马达;螺丝;齿轮装置,向所述螺丝传递所述马达的旋转力;及螺丝导件,根据所述螺丝的旋转而升降;根据所述螺丝导件的升降而调整车高。
优选地,所述齿轮装置,包括:蜗轮,设置在所述马达的轴;正齿轮,设置在所述蜗轮与所述螺丝之间,向所述螺丝传递所述蜗轮的旋转力。
并且,所述螺丝导件还可包括限制(limit)传感器,若达到预先设定的高度,使所述马达停止运转。
并且,还包括设置在所述马达的编码器。
并且,还可包括车高传感器,感应所述车辆的车高;根据所述车高传感器传送的信号而控制所述马达的动作。
另外,所述悬架支撑部为位于所述车辆前侧的前悬架(front suspension)支撑部。
或,所述悬架支撑部为位于所述车辆后侧的后悬架(rear suspension)支撑部。
(发明的效果)
具有所述结构的根据本发明的优选一实施例的车高调整装置,因利用马达及齿轮,其结构简单,能够节俭成本。
即,与空气悬架或液压悬架不同,无需另外设置气压线路及压缩器或液压线路及液压致动器等装置。据此,能够通过减少部件数量而简化工序并达成轻量化且节俭成本。

具体实施方式
下面,为了明确与本发明技术课题相关的解决方案,参照附图而详细说明本发明的优选实施例。但是,说明本发明时,判断为对相关公开技术的具体说明能够混淆本发明的要旨时,省略该说明。并且,后述的用语是考虑到其在本发明中的作用而定义的用语,会根据设计者、制造者等的意图或惯例等而不同。因此,应基于本说明书整体内容而定义。并且,整个说明书中以相同的附图编号(参照编号)标示的部分表示相同的构成要素。
下面,说明根据本发明的优选一实施例的车高调整装置。
参照图2至图4,根据本发明的优选一实施例的车高调整装置1,设置在支撑车辆(未图示)负荷的悬架弹簧2的上端部或支撑悬架弹簧2与悬架弹簧2的悬架支撑部3a、3b之间,从而调整车高(vehicle-height)。尤其,如同悬架弹簧2的问题,只在需要控制车高时调整车高,从而调整车高的高低。
所述车高调整装置1,如图2及图3所图示,可设置在A或B区域。即,所述车高调整装置1可分别设置在4个车轮侧。据此,能够在车辆的所述各个车轮侧,分别调整所述车辆的高度。
并且,所述车高调整装置1仅设置在前悬架(front suspension)支撑部3a或后悬架(rear suspension)支撑部3b侧,从而只调整车辆前侧的车高或车辆后侧的车高。
参照图4,所述车高调整装置1,包括:机壳100、螺丝导件200、螺丝300、齿轮装置400、马达500及下端支撑部600。
机壳100设置在悬架弹簧2的下端部而支撑向悬架弹簧2施加的负荷,或设置在悬架弹簧的上端部而使车辆的负荷施加到悬架弹簧2。
机壳100,如图4所图示,内部具有收容空间及一侧开口。而且,所述收容空间可设有螺丝导件200、螺丝300、齿轮装置400。并且,例示为马达500设置在机壳100的外部,但并不限定于此,也可设置在机壳100的内部。
螺丝导件200设置在机壳100的内部收容空间而根据螺丝300的旋转而升降。因此,机壳100根据螺丝导件200而升降,从而使悬架弹簧2升降,由此调整车高。
随着马达500的旋转,齿轮装置400把马达500的旋转力传递到螺丝300。因此,螺丝导件200随着螺丝300的旋转而升降。
这里,齿轮装置400,如图4所图示,包括蜗轮410及正齿轮420。
蜗轮410设置在马达500的一侧。而且,正齿轮420设置在蜗轮410与螺丝300之间而向螺丝300传递蜗轮410的旋转力。
通过利用蜗轮410与正齿轮420,只在需要控制车高时,通过蜗轮410启动正齿轮420,因行驶中的车高变化而正齿轮420想要旋转时,也会通过蜗轮410而阻止其旋转。
即,无法实现控制的状态下,无需另行驱动马达500,只有需要调整车高时,才启动马达500。从而消除了控制马达500的静止位置的必要性,能够减少马达500电力消耗。
根据本发明的一实施例,例示为所述车高调整装置1利用正齿轮420,但并不限定于此,为了向螺丝300传递马达500的旋转力,可利用螺旋齿轮等。但利用所述螺旋齿轮时,还需要控制马达位置。
下端支撑部600,如图4所图示,支撑螺丝300与正齿轮420共享的轴。
而且,所述车高调整装置1设置在A区域时,下端支撑部600的下部侧设有悬架支撑架3a、3b。并且,设置在B区域时,下端支撑部600的下部侧设有悬架弹簧2的上端部。
因此,传递到悬架弹簧2的车辆的负荷通过所述车高调整装置1而根据悬架弹簧2或悬架支撑部3a、3b所支撑。
另外,所述车高调整装置1可包括控制部700及车高传感器800。而且,可包括限制传感器810或编码器820而替代车高传感器800,。
车高传感器800感应车辆的车高。据此,向控制部700传送包括车高信息的信号。而且,控制部700根据车高传感器800的信号,驱动马达500而调整车高。
这里,车高传感器800可设置在车辆的各车轮侧。而且,还可以只设置在前方或后方的车轮侧。
编码器820可设置在马达500而替代车高传感器800。
并且,限制传感器810可替代车高传感器800。
限制传感器810感应螺丝导件200是否达到预先设定的高度。据此,螺丝导件200若达到预先设定的高度,使马达500的停止运转。
并且,螺丝导件200若未达到预先设定的高度时,限制传感器810向控制部700传送信号而使螺丝导件200达到预先设定的高度。而且,控制部700能够控制马达500而使螺丝导件200达到预先设定的高度。
根据本发明的多种实施例能够解决相应技术领域的技术问题以外,还能解决未在本说明书中提及的相关技术领域的其他技术课题。
以上参照实施例而说明了本发明。但本发明所属技术领域的技术人员能够在不脱离本发明本质技术特性的范围内,可进行多种变更。因此,本发明公开的实施例并不是限定性的,而是为了说明本发明。即,本发明的真正技术范围以公开于权利要求范围,与其同等范围内的所有差异都包括在本发明。
