The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Embodiment 1: as shown in Figures 1 to 4, a kind of front and back wheel interlock braking two-wheel car, comprise for the disc brake 100 of front wheel brake, for the drum of trailing wheel braking stop 200, hand braking mechanism 300, link gear 400.Disc brake 100 is controlled by oil pump 5, and drum is stopped and 200 is connected with brake rod 10, and brake rod 10 is connected with the first drag-line 6.
In other specific embodiment, also can adopt shoulder bolt to connect balance block 15 and handle 2, and save lining, to reach essentially identical technique effect.
Oil pump actuating mechanism 7 be can be around the shaft the rocking arm of 1 rotation, rocking arm one end drives by equalizing gear 4, the other end can be by the piston 5e of pressure oil pump 5.
On oil pump 5, one is arranged at intervals with the first flange 5a and the second flange 5b, and oil pump actuating mechanism 7 and handle 2 are arranged at the gap between the firstth flange 5a and the second flange 5b.Rotating shaft 1 is bolt, is connected successively through the first flange 5a, oil pump actuating mechanism 7, handle 2 with after the second flange 5b with jam nut 11.The front portion of oil pump 5 relative vehicles is provided with the 4th flange 5d, is provided with the through hole 5f passing through for the first drag-line 6a on the 4th flange 5d.The first drag-line 6a passes by being arranged at after 5f in balance block 15, and the first drag-line 6a passes through hollow bolt 24 guide-localizations, hollow bolt 24 and through hole 5f screw thread fit.
This device also comprises the stop gear of restriction oil pump actuating mechanism 7 end positions, and when oil pump actuating mechanism 7 moves to end position when static, equalizing gear 4 still can rotate centered by rotating shaft 1.
Stop gear comprises Limit screw 12.On oil pump 5, be wholely set upwardly extending the 3rd flange 5c, Limit screw 12 is fixed on the 3rd flange 5c by stop nut 13.In oil pump actuating mechanism 7, be provided with the limiting section 7a relative with Limit screw 12, when oil pump actuating mechanism 7 makes oil pump piston 5e move to end position, Limit screw 12 contacts with limiting section 7a.The end that Limit screw 12 is relative with limiting section 7a is set to round end, and therefore, a little overload appears in tolerable rocking arm 7.
According to Vehicle Driving Cycle road conditions, drg service condition etc., can, by adjusting the relative position of stop nut 13 and Limit screw 12, allow forward and backward drg reach best synchronous braking, gradual braking effect.
On two-wheel car, be hinged with rear brake pedal 19, the other end that rear brake pedal 19 is ridden is relatively connected with the second drag-line 20.The lower end of brake rod 10 is arranged at intervals with the first braking pin shaft support 10a, the second braking pin shaft support 10b, the 3rd braking pin shaft support 10c and the 4th braking pin shaft support 10d.The first braking pin shaft support 10a, the second braking pin shaft support 10b, the 3rd braking pin shaft support 10c and the 4th braking pin shaft support 10d are provided with relative bar hole 21.In the bar hole of the first braking pin shaft support 10a and the second braking pin shaft support 10b, be provided with the first braking pin shaft 22a, in the bar hole of the 3rd braking pin shaft support 10c and the 4th braking pin shaft support 10d, be provided with the second braking pin shaft 22b, the first braking pin shaft 22a is connected with the first drag-line 6; The second braking pin shaft 22b is connected with the second drag-line 20.The diameter of the first braking pin shaft 22a and the second braking pin shaft 22b is all less than the length of bar hole 21.Because the first braking pin shaft 22a and the second braking pin shaft 22b can rotate freely in corresponding bar hole 21, therefore the first drag-line 6 and the second drag-line 20 there will not be twisted phenomena, thereby drag-line motion is more smooth, operates lighter.
Under initial condition shown in Fig. 5, Fig. 6 and Fig. 7, during linkage braking device work, driver's bar handle 2, handle 2 is 1 rotation around the shaft, band dynamic balance weight 15 rotates, thereby the drag-line pin 23 that drives rotary type to be arranged on balance block 15 the latter halfs pulls the first drag-line 6, the first drag-lines 6 to pull bulging braking bar 10, reach the stop effect of 200 brakings of Back-braking drum.Also can step on rear brake pedal 19 with pin, rear brake pedal 19 is rotated, thereby drive the second drag-line 20 to pull brake rod 10, make trailing wheel braking.
When balance block 15 rotates, balance block 15 the first half cylinder 15a drive rocking arm 3 front ends, make rocking arm 71 rotation around the shaft, thereby make rocking arm 7 back-end contacts promote oil cylinder piston 5e, allow oil cylinder 5 inside brake oil enter in brake pump 17, the piston that promotes brake pump 17 with this clamps brake disc 18, reaches the effect of disc brake 100 front brakings.
Because the stroke of disc brake oil cylinder braking is shorter, therefore in the situation that the first drag-line 6 does not make brake rod 10 pull to put in place completely; the back-end contacts of rocking arm 7 has made oil pump piston 5e move to end position; as shown in Fig. 9, Figure 10 and Figure 11; therefore; limiting section 7a and Limit screw 12 are set to stop rocking arm further to move, thus reliability and the service life of improving oil pump 5; Simultaneously, because the cylinder 15a place on the corresponding balance block of rocking arm 7 15 tops is provided with the circular arc 7b of evagination, therefore, when the handle 2 of further holding with a firm grip makes handle 2 continue rotation, as shown in Figure 12, Figure 13 and Figure 14, balance block 15 will further be followed rotation, thereby make the first drag-line 6 strain brake rod 10, but make to keep rocking arm 3 in relatively static state.
After braking, release handle 2, makes handle 2 and balance block 15 be returned to initial condition, and meanwhile, rocking arm 7, under the effect of disc brake oil cylinder 5 retracing spring (not shown)s, is returned to initial condition.
Embodiment 2: as shown in figure 15, the structure of the present embodiment is substantially the same manner as Example 1, difference is that oil pump actuating mechanism 7 is provided with ball cage installation room 7c near balance block 15 one end, is provided with ball cage 14a and lower ball cage 14b in ball cage installation room 7c; The contact jaw of balance block and oil pump actuating mechanism 7 is bulb 15b; Bulb 15b stretches into ball cage installation room 7c and coordinates with upper ball cage 14a and lower ball cage 14b.
Other structures and the principle of work of the present embodiment are identical with embodiment 1.
Embodiment 3: as shown in Figure 15,16 and 17, the structure of the present embodiment is substantially the same manner as Example 1, difference is that balance block 15 is structure as a whole with oil pump actuating mechanism 7.The top of rotating shaft 1 is provided with circular hole 25, and oil pump actuating mechanism 7 is stirred oil pump 5 through after circular hole 25, and the diameter of circular hole 25 is greater than the external diameter of oil pump actuating mechanism 7.
Other structures and the principle of work of the present embodiment are identical with embodiment 1.
Embodiment 4: oil pump actuating mechanism is connected by universal joint cross with equalizing gear, therefore, when oil pump actuating mechanism moves to end position when static, equalizing gear still can be rotated further centered by rotating shaft.Other structures and the principle of work of the present embodiment are identical with embodiment 1.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical personnels are in the art complied with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
