Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, this self-regualting type hydraulic brake caliper assembly, comprise caliper 1, support 18 and self-adjustment structure, wherein, caliper 1 is provided with the movable friction plate 3 and static friction sheet 2 that are positioned at brake disc both sides, side caliper being positioned at movable friction plate is provided with the cylinder body 4 of hydraulic pressure, piston 10 is provided with in cylinder body 4 inside of hydraulic pressure, the apron 9 of lips piston the inner is equipped with, under the pressure effect of transmission fluid, promote piston move to cylinder mouth direction, push movable friction plate to brake disc, meanwhile, reaction force makes caliper move backward, caliper drives static friction sheet to push brake disc to, movable friction plate and static friction sheet clamp brake disc under the effect of transmitting hydraulic power, reach the object of car brakeing.
Support 18 is the parts be combined with caliper by supporting pin 19, its major function: one is that brake calipers is installed on main frame reliably; Two is ensure that caliper realizes float function by supporting pin.Relative sliding is kept by two supporting pins being symmetrical in oil cylinder center between caliper entirety and support, supporting pin adopts the two ends being bolted to caliper separately, on supporting pin between caliper and support, cover has the dust-proof cover 20 of rubber, is covered by its slip exposed part.
Self-adjustment structure comprises bearing pin 5, axle sleeve 6, Compress Spring 8, and axle sleeve 6 is located on caliper 1, and bearing pin one end is connected with axle sleeve by Compress Spring, and the bearing pin the other end matches with the ratchet of the inclination that piston 10 is arranged, and control piston can only move to movable friction plate direction.
Axle sleeve 6 is provided with endoporus, and endoporus is step hole, and bearing pin one end is through step hole, and bearing pin is provided with ledge structure, and Compress Spring is enclosed within bearing pin and is located in step hole.The inner of bearing pin is the oblique tip suitable with the skewed slot of ratchet, with the inclined-plane of the skewed slot of ratchet towards movable friction plate.
