Description
Technical field
The present invention relates to automotive brake technical field, specifically a kind of floating caliper type disc centre brake with automatic resetting mechanism.
Background technique
Along with the variation of modern offroad vehicle equipment, the deadweight of vehicle itself continues to increase, and security requirement improves constantly, and the braking ability of vehicle requires also more and more higher.At present, offroad vehicle central authorities floating caliper type disc centre brake causes parking braking Problem of Failure to be given prominence to because rear brake shoe is dawdled, and the mean distance between failures how improving parking braking is important topic in the industry.The friction plate return spring that former Parking Brake carries, after releasing parking braking, rear friction plate cannot overcome mechanical friction between caliper body and sliding pin and moment, rear friction plate is caused to be close to parking braking dish occurs braking to dawdle phenomenon, dawdle and directly cause rear friction plate premature abrasion and increase parking braking gap, after this gap increases above parking automatic backlash adjustment range, parking braking is just caused to be lost efficacy.Existing break mean distance between failures is 500Km, poor reliability.
Summary of the invention
The object of the invention is a kind of floating caliper type disc centre brake with automatic resetting mechanism for elimination causes parking braking to be lost efficacy because centre brake rear brake shoe is dawdled and design.
Technological scheme of the present invention: the floating caliper type disc centre brake of band automatic resetting mechanism of the present invention comprises centre brake caliper body, the pitman arm shaft be connected with centre brake caliper body and rocking arm, through the sliding pin of centre brake caliper body, sliding pin support, be arranged on the front brake lining on centre brake caliper body and rear brake shoe, center brake dish between front brake lining and rear brake shoe, breaking top pin assembly, front brake pad return spring, sliding pin between the rear end of centre brake caliper body and sliding pin support overlaps and has Compress Spring, centre brake caliper body stretches out a limiting board, limiting board is installed adjustable clearance stop screw, the sliding pin support at the corresponding Compress Spring place of rod end of adjustable clearance stop screw.
In centre brake caliper body, rectangular seal is established at the two ends of sliding pin.
Fit between described original state adjustable clearance stop screw and sliding pin support.
The described axis of adjustable clearance stop screw and the axis being parallel of pitman arm shaft.
Described adjustable clearance stop screw and the coaxial line of sliding pin.
Advantage of the present invention: this invention ensures that, in driving conditions, before and after parking, brake shoe is separated with brake disc, ensure that front brake lining and rear brake shoe balanced with the gap of center brake dish, make front and back brake shoe all can not cause phenomenon of dawdling.Reach the phenomenon eliminated eccentric wear and dawdle.Increase rectangular seal at former caliper body pin-and-hole two ends, avoid in vehicle using process, the impurity such as sand and dust, muddy water enters and causes caliper body stuck, causes front and back brake shoe to dawdle phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention: the floating caliper type disc centre brake of band automatic resetting mechanism of the present invention comprises centre brake caliper body 1, the pitman arm shaft 2 be connected with centre brake caliper body 1 and rocking arm 3, through the sliding pin 4 of centre brake caliper body 1, sliding pin support 5, be arranged on the front brake lining 6 on centre brake caliper body 1 and rear brake shoe 7, center brake dish 8 between front brake lining 6 and rear brake shoe 7, breaking top pin assembly 9, front brake pad return spring 10, sliding pin 4 between the rear end of centre brake caliper body 1 and sliding pin support 5 overlaps and has Compress Spring 11, centre brake caliper body 1 stretches out a limiting board 13, limiting board 13 is installed adjustable clearance stop screw 12, the sliding pin support 5 at corresponding Compress Spring 11 place of rod end of adjustable clearance stop screw 12.
In centre brake caliper body 1, rectangular seal 14 is established at the two ends of sliding pin 4.
Described original state, when namely not braking, when brake disc 8 is equal with the gap between front brake lining 6 and rear brake shoe 7, fits between adjustable clearance stop screw 12 and sliding pin support 5.Generally, front brake lining 6 and the gap between rear brake shoe 7 and brake disc 8 change at 0.5 ~ 1mm.
The axis of described adjustable clearance stop screw 12 and the axis being parallel of pitman arm shaft 2.
Described adjustable clearance stop screw 12 and the coaxial line of sliding pin 4.
Working principle: after releasing parking braking, because front brake lining 6 pulls open by the effect of front brake lining 6 return spring 10, have a gap with center brake dish 8; If the effect of return spring 10 is excessive, rear brake shoe 7 may be attached on center brake dish 8, causes rear brake shoe 7 that braking occurs on parking braking dish and to dawdle phenomenon; If the effect of return spring 10 is too small, may there is braking and to dawdle phenomenon (this is prior art Problems existing) in front brake lining 6 on parking braking dish.The present invention overlaps on the sliding pin 4 between the rear end and sliding pin support 5 of former centre brake caliper body 1 Compress Spring 11, after releasing parking braking, Compress Spring 11 resistance overcome between centre brake caliper body 1 and sliding pin 4 makes centre brake caliper body 1 return, rear brake shoe 7 also can leave center brake dish 8 one gaps, thus in guarantee driving conditions, before and after parking, brake shoe is separated with brake disc, reaches the phenomenon eliminated eccentric wear and dawdle.
The effect of position-limit mechanism is that the effect of limit compression spring 11 power makes centre brake caliper body 1 return.When entreating brake caliper body 1 return, when the gap that rear brake shoe 7 leaves center brake dish 8 reaches 0.5 ~ 1mm, be subject to the stop of adjustable clearance stop screw 12, stop motion, the elastic force of adjustable clearance stop screw 12 limit compression spring 11, ensure that front brake lining 6 and rear brake shoe 7 balanced with the gap of center brake dish 8, make front and back brake shoe all can not cause phenomenon of dawdling.Adjustable clearance stop screw 12 can regulate front brake lining 6 and the gap between rear brake shoe 7 and brake disc 8 to arrange and resemble.
Adopt rectangular seal 14 to avoid in vehicle using process, the impurity such as sand and dust, muddy water enters and causes caliper body stuck, causes front and back brake shoe to dawdle phenomenon.
