Description

Clipper disk brake

Technical field

The present invention relates to engineering machinery EPB technical field, specifically a kind of clipper disk brake.

Background technology

At present, the engineering machinery such as loading machine is interior shoe type drum type parking brake with EPB, be by brake drum, Brake-shoe, friction plate, cam, pull bar, spring etc. are formed.Major defect is big volume, complicated, poor reliability, installation dimension Repair inconvenience.After particularly repairing dismounting, once being stained with greasy dirt or into the grains of sand, brake is with regard to ineffective.And clean clear Except again pretty troublesome.

The content of the invention

It is an object of the invention to provide a kind of small volume, simple in construction, good reliability, pincers disk convenient to install and maintain braking Device.

The present invention is that technical scheme is as follows used by solving technical problem：

Clipper disk brake of the present invention includes fixed plate, the fix bar for being fixedly mounted on fixed plate one side, slip cap and is mounted in The first bearing and the second bearing in fix bar, the relative medial surface of first bearing and the second bearing are provided with friction plate, First bearing separately has for changing gap between the first bearing and the second bearing between fixed plate and the second bearing Clamping mechanism, the clamping mechanism are included through being inserted into the first bearing and axis on the second bearing, be sleeved on axis simultaneously The fixed disk and rotating disk that can be rotated against, the fixed disk are fixedly connected on the second bearing relative to the outer of the first bearing direction On side, it is provided with the rotating disk and drives the drawing of rotation disc spins bright, be provided with and slide between the fixed disk and rotating disk Guider, the slide guide device change both axial gap when fixed disk and rotating disk rotate against.

The slide guide device includes being arranged on fixed disk and guide groove on the relative madial wall of rotating disk, is arranged on Spheroid in guide groove, the guide groove are the multiple arcs grooves extended along axis circumferencial direction, and multiple arcs grooved ring is in Axle is uniformly distributed, the depth of the deep-slotted chip breaker by be deep to it is shallow seamlessly transit, the diameter of the spheroid is not less than deep-slotted chip breaker bosom Depth.

Spacer is set with fix bar between the first bearing and the second bearing；Drawing is fixedly connected with the second bearing Bright support, it is described draw bright support and draw it is bright between be provided with return spring.

It is the clipper disk brake small volume, simple in construction, good reliability, convenient to install and maintain as a result of said structure. Brake disc can be removed voluntarily after being stained with greasy dirt, remain no-sundries between brake disc and brake(-holder) block.Braking moment is big, can meet Large-tonnage loading machine requirement, using lever drive principle, reinforcement multiple is reached 10-30 times, reduce braking maneuver pulling force with Brake force is improved, shortens and brakes corresponding stroke and time.Automatically adjust brake block and the symmetrical function of brake disc.With higher Social value and economic value.

Embodiment

As shown in Figure 1, Figure 2, Figure 3 shows, clipper disk brake of the present invention includes fixed plate 13, is fixedly mounted on fixed plate 13 The first bearing 2 and the second bearing 3 of the fix bar 17 of one side, slip cap in fix bar 17, first bearing 2 and the The relative medial surface of two bearings 3 is provided with friction plate 11, and the first bearing 2 and the second bearing 3 can be slided in fix bar 17, changed Become gap between the two, so as to clamp brake disc between the two, realize braking function.In order to keep balancing, fix bar 17 There are two to be arranged in parallel, it is vertical with fixed plate 13, it is symmetricly set on the both ends of the first bearing 2 and the second bearing 3.

As shown in Figure 1, Figure 2, Figure 4 shows, first bearing 2 is located between the bearing 3 of fixed plate 13 and second, separately has for changing Become the clamping mechanism in gap between the first bearing 2 and the second bearing 3, the clamping mechanism, which includes running through, is inserted into the first bearing 2 With the axis 1 on the second bearing 3, the fixed disk 4 that is sleeved on axis 1 and can rotate against and rotating disk 5, axis 1 is located at two The centre position of root fix bar 17, parallel with fix bar 17, the both ends of axis 1 set nut, and thereon each is inserted for limit Part prevents from coming off.The fixed disk 4 is fixedly connected on lateral surface of second bearing 3 relative to the direction of the first bearing 2, described The drawing bright 6 that driving rotating disk 5 rotates is installed in rotating disk 5, as shown in Figure 1, shown in Figure 5, draws bright 6 one end to be bolted company It is connected on the lateral surface of rotating disk 5, pulling bright 6 free end can drive rotating disk 5 to rotate.The fixed disk 4 and rotation Slide guide device is provided between disk 5, the slide guide device changes both when fixed disk 4 and rotating disk 5 rotate against Axial gap.

As shown in Figure 6, Figure 7, the slide guide device includes being arranged on fixed disk 4 and the relative madial wall of rotating disk 5 On guide groove 121, the spheroid 12 in guide groove 121, the guide groove 121 be along the circumferencial direction of axis 1 extend Multiple arcs groove, multiple arcs grooved ring is uniformly distributed around axis 1, the depth of the deep-slotted chip breaker by be deep to it is shallow seamlessly transit, institute The diameter for stating spheroid 12 is not less than the innermost depth of deep-slotted chip breaker.To match the outline of spheroid 12, the section of the deep-slotted chip breaker For circular arc, it is gradually reduced from major part to the depth and width of microcephaly's deep-slotted chip breaker, in drops.The deep-slotted chip breaker can only be set On fixed disk 4 or the madial wall of rotating disk 5, deep-slotted chip breaker can also be respectively provided with the madial wall of fixed disk 4 and rotating disk 5. When rotating disk 5 rotates, spheroid 12 slides with being rotated in deep-slotted chip breaker for rotating disk 5, when spheroid 12 slides into deep-slotted chip breaker When higher depth, the major part of spheroid 12 is embedded into deep-slotted chip breaker, and the gap between fixed disk 4 and rotating disk 5 is smaller, and first Gap between the bearing 3 of bearing 2 and second is larger, and brake is in releasing orientation；When spheroid 12 slides into the shallower place of deep-slotted chip breaker When, the only small part of spheroid 12 is embedded in shallow slot, and thrust caused by spheroid 12 is by between fixed disk 4 and rotating disk 5 Gap enlargement, rotating disk 5 promotes the second bearing 3 to be moved to the direction of the first bearing 2 by spheroid 12, while is pulled by axis 1 First bearing 2 moves to the direction of the second bearing 3, the gap between the first bearing 2 and the second bearing 3 is compressed, by what is be located therein Chuck clamping is braked, realizes braking function.

As shown in Figure 1 and Figure 2, it is set with spacer 14 in the fix bar 17 between the first bearing 2 and the second bearing 3；Should be every Set 14 is made of elastomeric materials, on the one hand can separate the first bearing 2 and the second bearing 3, is limited between minimum between the two Gap, on the other hand when take-off the brake, the elasticity of spacer 14 can make the first bearing 2 and the return of the second bearing 3.Second It is fixedly connected with bearing 3 and draws bright support 16, it is described to draw bright support 16 and be provided with return spring 61 between drawing bright 6.The return The effect of spring 61 can make the return of rotating disk 5 when take-off the brake.
