Abstract

一种脚操作驻车制动器消除了手分离的需要。J形杆元件14枢转以将销20接合靠在推进单元10的轮胎22上。J形杆14具有安装于其上的可枢转踏板组件24，其可释放地与安装于支架12上的锁板30接合。操作者可通过用他或她的脚后跟压下踏板26的下部来释放所述制动器。

Description

用于推进车辆的脚制动器
技术领域
本申请要求2007年12月20日提交的系列号为61/015,546的美国申请的权益，其内容通过参考被并入。
背景技术
划线机推进单元是公知的，例如本发明的受让人用LineDriver商标出售的划线机推进单元。在这些单元中，汽油发动机直接驱动液压泵，该液压泵供应流体静力驱动系统。当在斜坡上且用于运输而操作时，具有驻车制动功能的能力是有帮助的。
发明内容
脚操作驻车制动器消除了现有技术设计的手分离的需要。J形杆枢转以将销接合靠在推进单元的轮胎上。J形杆具有安装在其上的可枢转踏板单元，该踏板单元可释放地与安装在支架上的锁板接合。操作者可通过用他或她的脚后跟压下踏板的下部来释放制动器。
从下述描述结合附图可更加全面地显示本发明的这些和其它的目的和优点，其中贯穿几个视图相同的附图标记指示相同或相似的部分。
附图说明
图1示出安装在推进单元上的本发明的踏板机构。
图2示出踏板上的回位弹簧细节。
图3示出分离的制动器。
图4示出接合的制动器。
具体实施方式
推进单元、例如将用于推进划线机(或推动割草机或多数任何其它后操纵器具)的推进单元通常被指定为10。J形杆焊接件14经由轴16可枢转地与支架12连接。销支架18连接至轴16且具有第一和第二销20，该第一和第二销20经由多个孔18a可调节地安装至该销支架18，设置第一和第二销20以便当制动器接合时摩擦地接合轮胎22。由孔18a提供的可调整性允许用于轮胎22和销20的磨损补偿。
踏板组件24由焊接或以其它方式连接至踏板锁元件28顶部的踏板26组成。踏板锁元件28可枢转地安装至J形杆14的顶端14a，且具有位于邻近锁板30的缺口28a，所述锁板30与支架12连接。踏板弹簧32安装在踏板组件24的枢转点处，以便将踏板锁元件28的下端28b朝向锁板30偏压。回位弹簧34用于偏压J形杆14以致销20不接合。
在操作期间，操作者只需按压踏板26直到销20压靠轮胎22。当脚压力释放时，缺口28a与锁板30接合并在适当的位置锁定制动器。当期望释放制动器时，操作者只需压下踏板的下部导致踏板锁元件28的下端28b与锁板30分离。
可以预期的是，可以对推进单元进行各种改变和改进，而没有偏离如由随后的权利要求所限定的本发明的精神和范围。

Claims (3)

1.在一种推进单元中，该推进单元具有支架和接合所述单元的轮胎的驻车制动器元件，改进包括：
在所述支架上的锁板；和
踏板组件，该踏板组件可枢转地安装到所述制动器元件且能够在第一位置和第二位置之间枢转，由此在所述第一位置中，所述踏板组件接合所述锁板以接合所述轮胎，并且由此在所述第二位置中，踏板组件从所述锁板分离。
2.如权利要求1所述的推进单元，其中所述踏板组件被朝向所述第一位置偏压。
3.如权利要求1所述的推进单元，进一步包括销和多个孔，该销用于接合所述轮胎，并且该多个孔用于将所述销相对于所述轮胎和所述制动器元件可调节地定位。
