    Abstract: The present invention relates to a mechanical parking drum brake for a vehicle. A leading brake shoe (16) and a trailing brake shoe (18) are coupled to a front of a backplate (14) by using an anchor pin (28) and return springs (20, 40, 42) so that each of the leading brake shoe (16) and the trailing brake shoe (18) rotates around an axis of the anchor pin (22) by a cam (30) having a cam shaft (28) to perform braking. A through hole (48) having a larger diameter than the cam shaft (28) is provided in the backplate (14). A first bracket (52) having a guide hole (50), which is elongated left and right, and a second bracket (56) spaced apart from the first bracket (52) to maintain a predetermined distance and having a shaft hole (54) to rotatably couple the cam shaft (28) are sequentially coupled to a back of the through hole (48) so that the cam shaft IS rotatable around shaft holes (24, 54) of the dust cover (12) and the second bracket (56) while movable left and right by the large through hole (48) of the back plate (12) and the guide hole (50) of the first bracket (52). Thus, an optimal brake force can be achieved by applying optimal force to each of the leading brake shoe (16) and the trailing brake shoe (18) and also a braking effect (output force/input force) is improved to a level equivalent to an effect of a hydraulic parking drum brake of a wheel cylinder structure.

    Abstract translation: 本发明涉及一种用于车辆的机械停车鼓式制动器。 引导式制动蹄片（16）和拖曳制动蹄片（18）通过使用固定销（28）和复位弹簧（20,40,42）联接到背板（14）的前部，使得每个前导 制动蹄（16）和后煞车蹄（18）通过具有凸轮轴（28）的凸轮（30）围绕锚定销（22）的轴线旋转以执行制动。 具有比凸轮轴（28）大的直径的通孔（48）设置在背板（14）中。 第一支架（52）具有左右伸展的导向孔（50）和与第一支架（52）间隔开并保持预定距离并具有轴孔（54）的第二支架（56） 以可旋转的方式联接凸轮轴（28）顺序地联接到通孔（48）的后部，使得凸轮轴可绕防尘罩（12）的轴孔（24,54）和第二支架（56）旋转 ），同时由后板（12）的大通孔（48）和第一支架（52）的引导孔（50）左右移动。 因此，可以通过对每个前导制动蹄片（16）和后煞车蹄（18）施加最佳的力，并且将制动效果（输出力/输入力）提高到等于 轮缸结构的液压驻车鼓制动器的作用。

    Abstract: PURPOSE: A drum brake for a vehicle is provided to maintain perpendicularity in repeated braking operation and to flexibly move a brake shoe for braking without occurring frictional noise. CONSTITUTION: A drum brake(10) for a vehicle comprises a back plate(12), a top and bottom wheel cylinder(14), brake shoes(18,20), and a return spring(22). Left and right brake shoes installed in the back plate is welded with a web inside a rim. The web is formed with a through-hole. The left and right pin bolts(32,24) of the back plate pass the through-hole to fit support plates(44,46) in a spiral part protruded to the top of the web and is screwed with nuts(48,50). A brake shoe is given with perpendicularity by surface-contacting with the web of the brake shoe in the non-contact state with the back plate.
