Specific implementation mode
The following examples can make professional and technical personnel that the present invention be more fully understood, but therefore not send out this
It is bright to be limited among the embodiment described range.
A kind of electric-controlled hydraulic integrated form multi-cylinder braking tongs as shown in Figures 1 to 4, including braking clamp body 1, piston 2, swivel nut
3, screw rod 4, inside brake block assembly 5, outer brake pad assembly 6, holder 7, guide pin 8 and bolt 9.
Setting is there are two being coaxially equipped with piston 2 on braking clamp body 1 in wheel cylinder 11 and wheel cylinder 11, two of braking clamp body 1
It is cast with channel between wheel cylinder 11；Setting is located at two wheel cylinders 11 there are one middle cylinder 12 and middle cylinder 12 on the braking clamp body 1
Between, it is coaxially equipped with the power part 33 of swivel nut 3 in the middle cylinder 12 and power part 33 coordinates with screw rod 4, on power part 33
It is provided with linking arm 32, the both ends of the swivel nut power part 33, which are respectively set, to be extended to and be mounted on there are one pressure head 31 and pressure head 31
Have in the wheel cylinder 11 of piston 2 with coaxially assembled in piston 2.
Holder 7 straddles in brake disc 10, and holder pilot hole is provided on holder 7；The braking clamp body 1 passes through bolt 9
It is fixedly linked and can be slided along holder pilot hole with guide pin 8, the screw rod 4 is mounted in braking clamp body 1 and 3 power part of swivel nut
Screw-drive mechanism is formed, the inside brake block assembly 5 is arranged symmetrically in 10 both sides of brake disc with outer brake pad assembly 6, described
Inside brake block assembly 5 and outer brake pad assembly 6 can be slided along rack groove.
The end of piston 2 is provided with 21 structure of gap.
The depth of 2 end gap 21 of piston is bigger 2.5mm or more than the thickness of 3 pressure head 31 of swivel nut.
Swivel nut 3 is integral type 31 symmetrical structure of double pressure heads, and 3 two pressure head transverse planes of the swivel nut are same plane, and are pressed
The rounded concave inward structure in head central area.
The pressure head 31 of swivel nut 3 is higher by 0.5mm or more than linking arm 32.
Operation principle is：
When service brake, the hydraulic pressure force actuation piston 2 in braking clamp body wheel cylinder 11 moves, and the piston 2 pushes inside brake block total
It is pressed against in brake disc 10 at 5, while the hydraulic coupling in the braking clamp body wheel cylinder 11 pushes braking clamp body 1 to be moved to piston
Negative direction moves, and the braking clamp body hooks pawl 13 and outer brake(-holder) block assembly 6 is driven to be pressed against on formulation disk 10, and final inside brake block is total
Brake disc is clamped with equal power at 5 and outer brake pad assembly 6, to achieve the purpose that vehicle deceleration or stopping；Parking braking
When, executing agency, which is powered, drives screw rod 4 to rotate, and since the rotation of the swivel nut 3 is limited by piston, the swivel nut 3 is pushed away by screw rod 4
Dynamic to move axially, the swivel nut 3 pushes inside brake block assembly 5 to be pressed against in brake disc 10, while the screw rod 4 is due to spiral shell
The negative direction that the axial reaction of set 3 drives braking clamp body 1 to be moved to swivel nut 3 moves, and the braking clamp body hook pawl 13 drives outer
Brake(-holder) block assembly 6 is pressed against in brake disc 8, and final inside brake block assembly 5 and outer brake pad assembly 6 clamp braking with equal power
Disk realizes parking braking, and due to the latching characteristics of screw rod swivel nut mechanism, after executing agency's power-off, the clamping force of caliper is constant,
Therefore it can realize that the function of long-time stable parking, the electric control braking can also realize emergency brake function in driving.
