Embodiment
Below against accompanying drawing, by the description to embodiment, the embodiment to the present invention makees further details of
Explanation.
As depicted in figs. 1 and 2, the self-adjustable hydraulic brake caliper assembly, including caliper 1, support 18 and self-adjusting mechanism, its
In, the side for being located at movable friction plate on the movable friction plate 3 and static friction piece 2 positioned at brake disc both sides, caliper is provided with caliper 1
Cylinder body 4 provided with hydraulic pressure, is provided with the apron 9 that lips are housed on piston 10, piston the inner, in transmission inside the cylinder body 4 of hydraulic pressure
The pressure effect of liquid is lower to promote piston to be moved to cylinder mouthful direction, pushes movable friction plate to brake disc, at the same time, reaction force makes
Caliper is moved backward, and caliper drives static friction piece to push brake disc to；Movable friction plate and static friction piece are under the effect of transmitting hydraulic power
Brake disc is clamped, the purpose of vehicle braking is reached.
Support 18 is the part combined by supporting pin 19 with caliper, its major function：One is to make caliper reliable
It is installed on main frame；Two be to ensure that caliper realizes float function by supporting pin.Pass through two between caliper entirety and support
The supporting pin for being symmetrical with oil cylinder center keeps relative and slided, and supporting pin each adopts the two ends for being bolted to caliper, caliper with
The dust cover 20 of rubber is cased with supporting pin between support, exposed part is slided and is covered.
Self-adjusting mechanism includes bearing pin 5, axle sleeve 6, compression spring 8, and axle sleeve 6 is located on caliper 1, and bearing pin one end is by compressing bullet
Spring is connected with axle sleeve, and the bearing pin other end is engaged with the inclined ratchet set on piston 10, and control piston can only be to dynamic friction
Move in piece direction.
Axle sleeve 6 is provided with endoporus, and endoporus is stepped hole, and bearing pin one end passes through stepped hole, and bearing pin is provided with ledge structure, compression
Spring housing is located in stepped hole on bearing pin.The inner of bearing pin is the beveled tip head being adapted with the skewed slot of ratchet, oblique with ratchet
The inclined-plane of groove is towards movable friction plate.
Piston, which is located at, to be located in the cylinder body in caliper, and the outer end periphery of piston is provided with a ring recess mouthful, and a ring recess is intraoral to be provided with
Dust ring 15, dust ring 15 is fixed by elastic spring 16, and the inner end periphery of piston is provided with apron.
Movable friction plate 3 is located in caliper by spring pull bar 12, and being provided between spring pull bar and caliper is used for movable friction plate
The return spring 11 of return.Static friction 2 is fixed on caliper by two bolts 13, equipped with a control after two friction plates
Moment of torsion processed produces the spring leaf 14 of centrifugal action to two friction plates.
Caliper 1 is provided with the air vent communicated with cylinder interior, and air vent is set close to the oil inlet of cylinder body, described to deflate
