摘要： A brake system of a minecar according to the present invention comprises brake shoes corresponding to left and right wheels of the minecar; brake arms having one side ends hinge-connected to the brake shoes for supporting the brake shoes respectively; tension units controlling the brake arms to adhere the brake shoes to the wheels respectively; and an actuator actuating the brake arm in a direction opposite to a control direction of a left and a right brake arm by the tension units to separate each of the brake shoes from the wheel. The tension unit includes a connecting member connecting the other end of each of the brake arms; a support rod having an upper end connected to a base frame and a lower end connected to the connecting member and a spring elastically pressing the support rod upwards. The actuator includes a cylinder arranged between the connecting member and the base frame; a pair of plungers arranged in an up and down symmetric direction within the cylinder and having protrusions; and an extension spring positioned between both the plungers for pressing both the plungers in opposite directions. The present invention basically maintains a braking state in a state that the minecar is separated from an engine locomotive and selectively releases the braking state according to a manipulation of a worker. Therefore, the present invention enhances stability of the minecar, accordingly has an advantage of enhancing work efficiency in performing a cargo loading or unloading work using the minecar.
摘要翻译：根据本发明的半导体制动系统包括对应于微型车的左右轮的制动蹄; 制动臂的一侧端铰链连接到制动蹄上，用于分别支撑制动蹄; 控制制动臂的张力单元分别将制动蹄附着在车轮上; 以及通过张力单元沿与左右制动臂的控制方向相反的方向致动制动臂的致动器，以将每个制动蹄与车轮分开。张紧单元包括连接每个制动臂的另一端的连接构件; 支撑杆，其上端连接到基部框架，下端连接到连接构件，弹簧弹簧将支撑杆向上按压。致动器包括设置在连接构件和基架之间的气缸; 一对在气缸内沿上下对称方向排列并具有突出部的柱塞; 以及定位在两个柱塞之间的拉伸弹簧，用于沿相反方向按压两个柱塞。本发明基本上在从发动机机车分离的状态下保持制动状态，并根据作业者的操纵有选择地释放制动状态。因此，本发明提高了精密度的稳定性，因此具有提高使用微型车进行货物装卸的工作效率的优点。
