根據上述構成,由於彈性部吸收接觸材之振動,故不需要接觸部之安裝時之調整,只要使接觸部與棘輪齒輪之齒接觸而安裝彈性部即可。因此,易於安裝規制由棘輪齒輪之振動引起之旋轉之規制部。 According to the above configuration, since the elastic portion absorbs the vibration of the contact material, there is no need to adjust the installation of the contact portion, and the elastic portion can be installed by bringing the contact portion into contact with the teeth of the ratchet gear. Therefore, it is easy to install the regulation part that regulates the rotation caused by the vibration of the ratchet gear.
上述制動件與車輪之間隙調整機構較佳具備固定前述接觸部與前述彈性部之螺桿。 The gap adjustment mechanism between the brake and the wheel preferably includes a screw that fixes the contact portion and the elastic portion.
根據上述構成,由於可藉由螺桿固定接觸部和彈性部,故易於安裝規制部。 According to the above configuration, since the contact portion and the elastic portion can be fixed by the screw, it is easy to install the regulating portion.
上述制動件與車輪之間隙調整機構較佳具備規制前述接觸構件之旋轉之止轉部。 The gap adjustment mechanism between the brake and the wheel preferably includes a rotation stop portion that regulates the rotation of the contact member.

上述制動件與車輪之間隙調整機構中,前述彈性部較佳為螺旋彈簧。 In the aforementioned mechanism for adjusting the gap between the brake and the wheel, the elastic portion is preferably a coil spring.
根據上述構成,由於彈性部為螺旋彈簧,故螺旋彈簧之負載應力小,經年變化小,故可減少彈性部之更換次數。 According to the above structure, since the elastic part is a coil spring, the load stress of the coil spring is small and the change over the years is small, so the number of replacements of the elastic part can be reduced.
解決上述課題之煞車缸具備:氣缸,其藉由空氣輸出煞車力;鞘桿,其傳遞前述氣缸之輸出;推桿,其安裝於前述鞘桿;及上述間隙調整器,其安裝於前述鞘桿。 The brake cylinder that solves the above problems includes: a cylinder, which outputs braking force through air; a sheath rod, which transmits the output of the cylinder; a push rod, which is mounted on the sheath rod; and the lash adjuster, which is mounted on the sheath rod .

鞘桿24相對於活塞22可旋轉地連接。推桿25螺合於鞘桿24。因此,當鞘桿24旋轉時,活塞22不旋轉,推桿25在與鞘桿24之旋轉方向對應之軸向之任一方向上移動。
The
於缸筒21之底部21A(圖中左側),設置有對缸筒21內供給壓縮空氣之供給口26。壓縮空氣被供給至由缸筒21與活塞22包圍之作動室27。若對作動室27供給壓縮空氣,則煞車缸1之活塞22向離開缸筒21之底部21A之方向移動。另一方面,若自作動室27排出壓縮空氣,則煞車缸1之活塞22藉由釋放彈簧23向接近缸筒21之底部21A之方向移動。

下移動之斜面13A。於調整推桿33之基端設置有在凸輪13之斜面13A上滾動之滾子33A。凸輪13設置於框體10之筒部11之內壁。凸輪13可對應於車輪與制動件之所期望之間隙,藉由設置在蓋12之螺栓而朝鞘桿24之軸向變更。若推桿25推進,則滾子33A在凸輪13之斜面13A上升,從而滾子33A提升,調整推桿33向上移動。即,滾子33A之提升量與調整推桿33之移動量一致。
The
如圖2所示,間隙調整器30具備作為爪部之棘爪34,該棘爪34相應於調整推桿33之上下移動而旋轉。棘爪34在車輪與制動件之間隙為規定值以上時,越過棘輪齒輪32之一齒,而與下一個齒頂嚙合。而若制動被解除,則調整推桿33向下方移動,棘爪34使棘輪齒輪32旋轉一齒之量。
As shown in FIG. 2, the
(規制部40) (Regulation Department 40)
如圖2~圖4所示,間隙調整器30具備規制部40,該規制部40規制由棘輪齒輪32之振動引起之旋轉。規制部40設置於鞘桿外筒31之上表面。規制部40具備個別構件之:作為與棘輪齒輪32之齒接觸之接觸部之棘輪按壓件41,以及作為吸收棘輪按壓件41之振動之彈性部之螺旋彈簧42。棘輪按壓件41具有與棘輪齒輪32之齒接觸之圓柱狀之按壓部41A。棘輪按壓件41由螺旋彈簧42予以彈推。
As shown in FIGS. 2 to 4, the
規制部40具備作為按壓構件之彈簧按壓件43,該彈簧按壓件43以特定值壓縮螺旋彈簧42。彈簧按壓件43具備:圓筒部43A,其插通於螺旋彈簧42之內側;及凸緣部43B,其與螺旋彈簧42之上端接觸。螺旋彈簧42被彈簧按壓件43之凸緣部43B壓縮,螺旋彈簧42之壓縮根據圓筒部
43A之長度而被規定為特定值。
The
規制部40具備作為將棘輪按壓件41與螺旋彈簧42固定於鞘桿外筒31之螺桿之螺栓44。棘輪按壓件41具有非供螺旋彈簧42插通而供彈簧按壓件43插通之貫通孔41B。彈簧按壓件43貫通棘輪按壓件41。螺栓44貫通插通於螺旋彈簧42之彈簧按壓件43及棘輪按壓件41之貫通孔41B,而螺合於鞘桿外筒31之母螺紋31A。彈簧墊圈46夾在螺栓44之螺桿頭與彈簧按壓件43之凸緣部43B之間。彈簧墊圈46夾在棘輪按壓件41與鞘桿外筒31之間。藉由該等彈簧墊圈46而抑制螺栓44鬆動。

The regulating
其次,說明上述間隙調整器30之動作。
Next, the operation of the above-mentioned
如圖1所示,若自缸筒21之供給口26向作動室27供給壓縮空氣,則活塞22抗著釋放彈簧23之作用力而向離開缸筒21之底部21A之一側即圖1中右側移動。然後,若活塞22向圖1中右側移動,則推桿25經由與活塞22連接之鞘桿24與活塞22成為一體向圖1中右側前進。
As shown in FIG. 1, if compressed air is supplied from the
若鞘桿24向圖1中右側移動時,間隙調整器30向圖1中右側移動,調整推桿33之滾子33A於凸輪13之斜面13A上升,藉此調整推桿33向上方移動。若調整推桿33向上方移動,則棘爪34向圖2中之逆時針方向旋轉。
If the
如圖2所示,在車輪與制動件之間隙不足規定值而推桿25之前進量小於規定值時,棘爪34利用滾子33A之提升量(調整推桿33之移動量),於棘輪齒輪32不會越過一齒,而棘輪齒輪32不旋轉。
As shown in Figure 2, when the gap between the wheel and the brake is less than the specified value and the advance of the
另一方面,在車輪與制動件之間隙為規定值以上而推桿25之前進量為規定值以上時,棘爪34利用滾子33A之提升量(調整推桿33之移動量)越過棘輪齒輪32之一齒,而與下一齒頂嚙合。而且,若自該狀態藉由自作動室27排出壓縮空氣而解除制動,則隨著推桿25向與進入方向相反之方向移動,而調整推桿33在凸輪13之斜面13A下降,藉此棘爪34使棘輪齒輪32旋轉一齒之量。藉由棘輪齒輪32旋轉,而與棘輪齒輪32固定為一體之鞘桿24亦旋轉,與鞘桿24螺合之推桿25向前進方向移動而位置被調整。
On the other hand, when the gap between the wheel and the brake is greater than the predetermined value and the advancement of the
間隙調整器30之規制部40藉由始終與棘輪齒輪32之齒接觸,而規制由棘輪齒輪32之振動引起之旋轉。規制部40之棘輪按壓件41由螺旋彈簧42彈推。該螺旋彈簧42被彈簧按壓件43壓縮為特定值,故不需要如先前之板簧之調整,僅藉由組裝規制部40之構件而可以特定之彈推力來規制棘輪齒輪32之旋轉。又,棘輪按壓件41之按壓部41A與棘輪齒輪32之齒接觸,螺旋彈簧42吸收棘輪按壓件41之振動。因此,藉由使棘輪齒輪32之接觸之功能與振動吸收之功能設為不同構件,而可不需要各自之組裝之調整。
The regulating
其次,對本實施形態之效果進行說明。 Next, the effect of this embodiment will be explained.
(1)由於螺旋彈簧42吸收棘輪按壓件41之振動,因此不需要在棘輪按壓件41安裝時進行調整,只要使棘輪按壓件41與棘輪齒輪32之齒接觸,且安裝螺旋彈簧42即可。因此,易於安裝規制由振動引起之棘輪齒輪32之旋轉之規制部40。
(1) Since the
(2)由於可藉由螺栓44來固定棘輪按壓件41與螺旋彈簧42,故易於安裝規制部40。
(2) Since the
