The gap between the left end of the primary oil cylinder 14 and the secondary oil cylinder 11 is S1, and S1>0. At this time, the double-acting brake caliper is at the initial installation position;

如图5所示,双作用刹车钳实现工作制动过程具体实施方案如下:As shown in Figure 5, the specific implementation plan of the double-acting brake caliper to realize the working braking process is as follows:

一级油缸14远离二级油缸11的一端分别开设有油孔A20和排气孔B23,排气孔B23用于消除油孔A20进入压力油时产生的气压;The end of the primary oil cylinder 14 away from the secondary oil cylinder 11 is respectively provided with an oil hole A20 and a vent hole B23, and the vent hole B23 is used to eliminate the air pressure generated when the oil hole A20 enters the pressure oil;

当压力油P1从油孔A20进入一级油缸14内腔,二级油缸11在压力油的推力下向左滑动,二级油缸11推动活塞杆8向左伸出,活塞杆8绕端盖A17转动带动左连杆6旋转,左连杆6带动左闸靴4向右旋转,左闸靴4带动左闸瓦2向右旋转通过摩擦力f1压紧刹车盘1,实现刹车;When the pressure oil P1 enters the inner cavity of the primary oil cylinder 14 from the oil hole A20, the secondary oil cylinder 11 slides to the left under the thrust of the pressure oil, the secondary oil cylinder 11 pushes the piston rod 8 to extend to the left, and the piston rod 8 wraps around the end cover A17 The rotation drives the left connecting rod 6 to rotate, the left connecting rod 6 drives the left brake shoe 4 to rotate to the right, and the left brake shoe 4 drives the left brake shoe 2 to rotate to the right and presses the brake disc 1 by the friction force f1 to realize braking;

与此同时,二级油缸11右端与一级油缸14间隙S2从零逐渐增大,碟簧13继续被压缩,直到一级油缸14左端头和二级油缸11间隙为S1=0停止压缩;At the same time, the gap S2 between the right end of the secondary oil cylinder 11 and the primary oil cylinder 14 gradually increases from zero, and the disc spring 13 continues to be compressed until the gap between the left end of the primary oil cylinder 14 and the secondary oil cylinder 11 is S1=0 to stop compression;

一级油缸14在压力油推力下向右滑动,一级油缸14推动顶杆9向右伸出,顶杆9绕端盖A17转动带动右连杆7旋转,右连杆7带动右闸靴5向左旋转,右闸靴5带动右闸瓦3向左旋转通过摩擦力f1压紧刹车盘1,实现刹车;The primary oil cylinder 14 slides to the right under the thrust of the pressure oil, the primary oil cylinder 14 pushes the ejector rod 9 to extend to the right, the ejector rod 9 rotates around the end cover A17 to drive the right connecting rod 7 to rotate, and the right connecting rod 7 drives the right brake shoe 5 Rotating to the left, the right brake shoe 5 drives the right brake shoe 3 to rotate to the left and presses the brake disc 1 through the friction force f1 to realize braking;
