Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
Embodiment one
As depicted in figs. 1 and 2, the active adjuster of a kind of disk brake, including self-regulated component and adjusting sleeve 29, it is described
One end rotary moveable of adjusting sleeve 29 is connected with push plate 292.The self-regulated component includes adjustment axis 22 and adjusts pulling block, described
Adjusting sleeve 29 be equipped with and the adjustment matched accommodating cavity 291 of pulling block, in the described adjustment pulling block insertion accommodating cavity 291.Also wrap
Fixed plate 20 is included, the adjustment axis 22 passes through fixed plate 20 and connect with 20 rotary moveable of fixed plate；The fixed plate 20
Torque reset spring 28 is equipped between sleeve 221.Fixed plate 20 with brake pedestal 1 for connecting, torque reset spring 28
For in brake release, tune to pull out set 21 and rotates backward.
As Figure 1-Figure 4, the adjustment pulling block includes the outer pulling block 24 and interior pulling block 25 being set on adjustment axis 22,
The adjustment axis 22 includes mandrel and the sleeve 221 that is set on mandrel and is fixedly connected with mandrel, on the sleeve 221
Equipped with boss corresponding with outer 24 one end of pulling block, the outer pulling block 24 is arranged between interior pulling block 25 and boss, the adjustment
Axis 22 is equipped with the limited block being axially moved for limiting interior pulling block 25.The setting of preloading spring 26 is in interior pulling block 25 and outside
Between pulling block 24.Opposite end face is respectively equipped with one-to-one cavity 245 between the outer pulling block 24 and boss, corresponding
Transmitting balls 23 are equipped between two cavitys 245；The preload for compressing transmitting balls 23 is additionally provided on the adjustment axis 22
Spring 26.It is also arranged with tune outside the adjustment axis 22 and pulls out set 21, the tune pulls out set 21 and passes through unilateral bearing with adjustment axis 22
27 connections.
As shown in Figure 5 and Figure 6, the outer rim side of the outer pulling block 24 is equipped with several transmission protrusions 241, the accommodating cavity
291 cavity wall is equipped with the groove 293 for matching and axially extending with transmission protrusion 241, the transmission protrusion 241 and groove 293
Between be equipped with elastic component.The elastic component is that the elastic cushion 242 for being driven raised 241 surfaces is arranged in, the elastic cushion 242
With a thickness of 0.5 ~ 1.2mm, the elastic component is made of rubber.
In braking, set rotation is alloted in pressure arm drive, and adjustment axis 22 is driven to rotate simultaneously, and adjustment axis 22 passes through transmission
Ball 23 drives outer pulling block 24 to rotate, and is passed between outer pulling block 24 and adjusting sleeve 29 by transmission protrusion 241 and the cooperation of groove 293
It is dynamic, it is connected through a screw thread between usual adjusting sleeve 29 and brake pedestal 1, adjusting sleeve 29 carries out axial fortune while rotation
It is dynamic, complete the adjustment of brake clearance.
After brake clearance completely eliminates, do not released if braking at this time, since friction plate is not moving, adjusting sleeve 29
It pulling block namely is not being rotated with adjustment.But under the driving of pressure arm, tune pulls out set 21 and adjustment axis 22 still rotates, when adjustment axis
After relative motion trend between 22 and adjustment pulling block reaches a certain amount of, transmitting balls 23 roll between adjacent cavity 245, disappear
Except movement tendency, playing prevents from adjusting excessive effect.In brake release, tune pulls out 21 for counter motions of set, pulls out set 21 due to adjusting
With adjustment axis 22 single-direction transmission in the circumferential, adjusting axis 22 at this time will not be rotated with it, and effectively prevent the production again of brake clearance
It is raw.
In addition, can occur to slide relatively between transmission protrusion 241 and groove 293 due to when gap adjusts, transmission protrusion
There are a small amount of gaps between 241 and groove 293.Therefore when gap adjusts, it may appear that response speed is slow, brake operating distance
The problems such as lengthening.The time that whole process works when automobile emergency brake is shorter, and above-mentioned response speed is slow and operating distance lengthens institute's band
The delay come, might have great influence.Increase elastic component between drive lugs and groove 293, guarantees drive lugs
Between groove 293 under the premise of sliding capability, gap between the two is eliminated, accelerates the corresponding speed of brake clearance adjustment
Degree, improves the security performance of braking system entirety.
Embodiment two
As shown in fig. 7, compared with embodiment one, the present embodiment the difference is that, the elastic component is that setting exists
It is driven the elastic strip 243 of raised 241 sides, in transmission, the transmission protrusion 241 and the surface that groove 293 compresses are front end
Face, the surface away from front end face are or hold that the rear end face of transmission protrusion 241 is arranged in the elastic strip 243.The elastic strip
243 section is rounded, and diameter is 2 ~ 3mm.
As shown in figure 8, a kind of disk brake, including brake pedestal 1, the brake pedestal 1 are equipped with driven
