Specific embodiment
The following examples can make professional and technical personnel that the utility model be more fully understood, but therefore will not
The utility model is 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, interior brake pad assembly 5, outer brake pad assembly 6, bracket 7, guide pin 8 and bolt 9.
Setting is coaxially equipped with piston 2 there are two wheel cylinder 11 and in wheel cylinder 11 on braking clamp body 1, and two of braking clamp body 1
Channel is cast between wheel cylinder 11；It is provided with a middle cylinder 12 on the braking clamp body 1 and middle cylinder 12 is located at two wheel cylinders 11
Between, it is coaxially equipped with the power part 33 of swivel nut 3 in the middle cylinder 12 and power part 33 and screw rod 4 cooperate, on power part 33
It is provided with linking arm 32, the both ends of the swivel nut power part 33 are respectively arranged with a pressure head 31 and pressure head 31 is extended to and is mounted on
Have in the wheel cylinder 11 of piston 2 with coaxially assembled in piston 2.
Bracket 7 straddles in brake disc 10, and bracket pilot hole is provided on bracket 7；The braking clamp body 1 passes through bolt 9
It is fixedly linked and can be slided along bracket 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 interior brake pad assembly 5 is arranged symmetrically in 10 two sides of brake disc with outer brake pad assembly 6, described
Interior brake pad 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 2.5mm or more bigger 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.
Working principle is:
When service brake, the hydraulic force actuation piston 2 in braking clamp body wheel cylinder 11 is mobile, and the piston 2 pushes interior braking
Block assembly 5 is pressed against in brake disc 10, while the hydraulic coupling in the braking clamp body wheel cylinder 11 pushes braking clamp body 1 to move to piston
Dynamic opposite direction movement, the braking clamp body hook pawl 13 and outer brake(-holder) block assembly 6 are driven to be pressed against on formulation disk 10, final interior braking
Block assembly 5 and outer brake pad assembly 6 are with equal power clamping brake disc, to achieve the purpose that vehicle deceleration or stopping；Parking
When braking, executing agency's driving screw rod 4 that is powered is rotated, and since the rotation of the swivel nut 3 is limited by piston, the swivel nut 3 is by spiral shell
The promotion of bar 4 can only move axially, and the swivel nut 3 pushes interior brake pad assembly 5 to be pressed against in brake disc 10, while the screw rod 4
Since the axial reaction of swivel nut 3 drives braking clamp body 1 to move to the mobile opposite direction of swivel nut 3, the braking clamp body hooks pawl 13
Outer brake(-holder) block assembly 6 is driven to be pressed against in brake disc 8, final interior brake pad assembly 5 and outer brake pad assembly 6 are pressed from both sides with equal power
Tight brake disc realizes parking braking, due to the latching characteristics of screw rod swivel nut mechanism, after executing agency's power-off, the clamping force of caliper
It is constant, therefore can realize the function of long-time stable parking, which can also realize emergency brake function in driving.
