The specific embodiment

See also Fig. 1 to shown in Figure 3, the simple pendulum arm Disk brake device that the utility model one preferred embodiment is provided includes:

One disc 10 is fixed in a wheel hub 70, and this disc 10 can be rotated with this wheel hub 70.This disc 10 has one first 11 and 1 second 12.

Two guide rods 20 are to be two bolts by it in appearance, and each guide rod 20 has a head 21 and a bar portion 22, and wherein this bar portion 22 is smooth round bar, have one section screw thread 23 near this head 21, and are having a wall portion 24 near free end.This two guide rod 20 is locked two screws 74 on the support 72 of being located at a front vehicle fork or rear vehicle fork respectively, and outside making that this bar portion 22 is parallel and extending side by side.

One pedestal 30 generally is a microscler block, has a base segment 31 and an extension 32.The guide hole 33, brake bar 34, an axis hole 35 and the screw 36 that have two side direction on this base segment 31, wherein should brake bar 34 between this two guide hole 33, be fixed with a brake facing 37 on it, this axis hole 35 is positioned at this brake bar 34 tops, but still between this two guide hole 33, and this screw 36 is positioned at the desired location of these pedestal 30 extensions 32 near the outer end.

This pedestal 30 is sheathed on the bar portion 22 of this two guide rod 20 with this two guide hole 33, and this pedestal 30 is engaged on the support 72 of (back) car fork before this, and the wall portion 24 of this two guide rod 20 is for avoiding the usefulness of these pedestal 30 these two guide rods 20 of disengaging.This bar portion 22 exposes to the outer part of support 72, and its length (deduction wall portion 24) is greater than the thickness of this pedestal 30, and therefore, this pedestal 30 can be generally moves along the bearing of trend of this two guide rod 20.When this defines this pedestal 30 and moves to the support 72 of (back) car fork before this of reclining is the one primary importance, and when this pedestal 30 behind the mobile preset distance in the outer end of this guide rod (wall portion 24), then arrive a second place.

The base segment 31 of this pedestal 30 is sides of first 11 that are positioned at this disc 10, make this brake facing 37 first 11 in the face of this disc 10, and (this brake facing 37 is positioned at more the outer rim near this disc 10 on the practice to be positioned at a desired location away from this disc 10 centers one preset distance, producible brake better effects if, but preferably still keep all areas of this brake facing 37 all can contact this disc 10).First 11 of this brake facing 37 and this disc 10 keep a preset distance (can keep 0.1mm to 2mm on the practice).The serve as reasons outwardly-bent extension of an end of this base segment 21 of the extension 32 of this pedestal 30 makes second 12 the side of the position of this screw 36 at this disc 10.

One swing arm 40, central authorities have an axis hole 41, and are divided into a driving section 42 and one retaining segment 43 with these axis hole 41 2 lateral areas.This swing arm 40 has a perforation 44 at the end of this driving section 42, and has a brake bar 45 at the end of this dog point 43, is fixed with a brake facing 46 on it.

This swing arm 40 is passed this axis hole 41 by a bolt 47 and is locked in the axis hole 35 of this pedestal 30, and this swing arm 40 can be swung in a predetermined angular for the axle center by this bolt 47.The retaining segment 43 of this swing arm 40 is positioned at a side of second 12 of this disc 10, make this brake facing 46 corresponding to the brake facing on the pedestal 37, and the driving section 42 of this swing arm 40 extends to a side of first 11 of this disc 10, and is relative with the extension 32 of this pedestal 30.

One brake cable 50 has a sleeve pipe 51, one ends and passes the perforation 44 that this swing arm 40 drives on the section 42, and lock the screw 36 of these pedestal 30 extensions 32 by a screw 38 and a nut 39, and is fixed in this pedestal 30; The other end of this brake cable 50 then is connected to a brake controller (not shown).Thus, the user can spur this brake cable 50 by driving this brake controller.

One spring 60 is sheathed on this brake cable 50, and between the driving section 42 of the extension 32 of this pedestal 30 and swing arm 40, and two ends are respectively against the two.So made the brake facing 3 in this pedestal 30 and this

swing arm

40,46, under initial condition (or not strained condition), do not contact with this disc 10.

By above structure, when the user operates this brake controller and spurs brake cable wire 50, this swing arm 40 can because of swing and make this brake facing 46 compress this disc 10; Simultaneously, the extension 32 of this pedestal 30 also is pulled simultaneously, and makes this base segment 31 along this two guide rod 20, moves to the second place by this primary importance, causes this brake facing 37 to compress this disc 10, as Fig. 5 and shown in Figure 7; And after the user decontroled the brake controller, the restoring force of this spring 60 can order about this pedestal 30 and get back to initial position with this swing arm 40, as Fig. 4 and shown in Figure 6.

The utility model has the advantage of:

1. simple structure, failure rate is low:

The group of single-swing arm disc brake provided by the utility model want element only have this two Guide rod, pedestal, this swing arm, this brake cable and this spring; Because the more existing dish of number of elements The formula brake device is few, and the chance that therefore produces fault is also lower.

2. assembling is easily:

Single-swing arm disc brake provided by the utility model there is no and anyly smallly is difficult to assemble Element, therefore comparatively easy in assembling, make on the manufacturing cost and can therefore and significantly reduce, and carry The market competitiveness of high product.

3. the brake effect is comparatively excellent:

When single-swing arm disc brake of the present utility model produces the brake effect, even slightly Under the situation of brake, the brake block in this pedestal and this swing arm can compress two sides of this disc simultaneously, Stable and balanced brake effect so can be provided.
