Description
上記課題を解決するユニットブレーキは、空気によってブレーキ力を出力する空気シリンダと、前記空気シリンダの出力を伝達する伝達駆動部と、前記伝達駆動部に取り付けられる制輪子頭と、上記隙間調整器とを備える。 Unit brake for solving the above air cylinder for outputting a braking force by air, and the transmission drive unit for transmitting an output of said air cylinder, and head the transmission driving system is attached to the unit wheel element, the gap regulator And prepare.
図３に示すように、引張ばね５４は、ラチェット爪４２に係合することで、ラチェット爪４２を開口部５５に位置させる。また、引張ばね５４は、ラチェット爪４２の第２係合軸４２Ｂと保持部材４３の第１係合軸４７とに係合することで開口部５５を閉じるとともに、図５に示すように、ラチェット爪４２の第２係合軸４２Ｂとの係合を外されることで開口部５５を開く。よって、引張ばね５４が開口部５５を開閉する開閉部として機能する。ラチェット爪４２は、連結ピン５３Ｂを中心に図５中時計回りに回転して枠体５０の開口部５５を開く。 As shown in FIG. 3, the tension spring 54 engages with the ratchet claw 42 to position the ratchet claw 42 at the opening 55. Further, the tension spring 54 closes the opening 55 by engaging with the second engaging shaft 42B of the ratchet claw 42 and the first engaging shaft 47 of the holding member 43, and as shown in FIG. 5, the ratchet The opening 55 is opened by disengaging the claw 42 from the second engaging shaft 42B. Therefore, the tension spring 54 functions as an opening / closing portion for opening / closing the opening 55. The ratchet claw 42 rotates clockwise in FIG. 5 around the connecting pin 53B to open the opening 55 of the frame body 50.
