Description

The bicycle brake linkage

Technical field

The utility model relates to bicycle brake device, particularly a kind of device of realizing bicycle front and rear wheel brake interlock.

Background technology

Generally, bicycle front and rear wheel brake respectively by left and right brake control, realize braking separately; Further improved be before, the rear wheel brake line is braked control brake simultaneously by a left side or the right side by an interlinked mechanism, as Chinese patent---the bicycle brake synchronizer (patent No.: 00100759.9), this interlinked mechanism comprises body, wall scroll brake cable and be slidingly installed in slide plate on the body, on the slide plate, the below is provided with the pulley of winding wall scroll brake cable and the pulley of winding interlock cable wire, slide plate top pulley is provided with connecting element, the wall scroll brake cable that two ends are connected on the Brake lever of the bicycle left and right sides is fixed on the connecting element of top pulley, a left side or right brake lever as long as hold with a firm grip like this, before can both stopping tightly simultaneously, trailing wheel, but it is preceding, trailing wheel brakes simultaneously, effect is obvious, and the cyclist has plunging sensation, if front-wheel is than the slow beat brake of trailing wheel, play the buffering brake, just do not had plunging sensation.

Summary of the invention

In order to remedy above deficiency, the utility model provides a kind of bicycle brake linkage, can realize the brake that successively links of trailing wheel and front-wheel, reaches the purpose of buffering brake, and the cyclist does not have the sensation to preshoot.

The technical solution of the utility model is such realization: a kind of bicycle brake linkage, comprise link gear and be connected in this link gear before, rear wheel brake line and brake are bus, this link gear comprises body with inner cavity chamber and the slide block that can slide in this inner cavity chamber, before being somebody's turn to do, the rear wheel brake sleeve pipe is fixed in this body one end side by side, and this brake is fixed in this body other end to sleeve pipe, this slide block is provided with two knock holees and an adjustment hole side by side, before being somebody's turn to do, the rear wheel brake interior lines are fixed two stop blocks respectively after corresponding knock hole is passed in a side activity, and these preceding wheel brake interior lines also activity wear compression spring, fix corresponding stop block again, this brake is passed interior lines this adjustment hole and is fixed in this adjustment hole by governing screw from opposite side.

As further improvement of the utility model, to should front-wheel the knock hole of brake interior lines be stepped hole, this preceding wheel brake interior lines activity is passed behind this stepped hole and is worn this compression spring, fixes corresponding stop block again, and this compression spring can be placed in this stepped hole anchor ring.

As further improvement of the utility model, knock hole aperture that should the rear wheel brake interior lines is formed recess, be convenient to that corresponding stop block is positioned in this recess in this rear wheel brake.

As further improvement of the utility model, this body is made up of loam cake and lower cover that slidably staving, the insertion type of ccontaining this slide block are installed on these staving two ends, this loam cake and lower cover and this staving form the inner cavity chamber of this body, be covered with a stepped hole on being somebody's turn to do, this brake is stretched into the interior lines activity in this staving when being convenient to this brake and being positioned sleeve pipe in this stepped hole, this lower cover is provided with two stepped holes side by side, when being convenient to this front and rear wheel brake sleeve pipe and being positioned in the corresponding stepped hole these front and rear wheel brake interior lines respectively activity stretch in this staving.

Useful technique effect of the present utility model is: described front and rear wheel brake interior lines are fixed two stop blocks respectively after corresponding knock hole is passed in slide block one side activity, these preceding wheel brake interior lines also activity wear compression spring, fix corresponding stop block again, can realize that like this trailing wheel is prior to preceding wheel brake, and the front-wheel braking strength progressively increases, meanwhile described brake is passed interior lines this adjustment hole and is fixed in this adjustment hole by governing screw from the slide block opposite side, can adjust brake like this displacement, the effect that the control brake is total.

To should front-wheel the knock hole of brake interior lines be stepped hole, this preceding wheel brake interior lines activity is passed behind this stepped hole and is worn compression spring, fix corresponding stop block again, this compression spring can be placed in this stepped hole anchor ring, wheel brake was with respect to the delay degree of rear wheel brake before design helped controlling like this, be convenient to install and adjust, reaching whole brake has better buffering effect.

The specific embodiment

In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, below be further described:

A kind of bicycle brake linkage, as shown in Figure 1, comprise link gear and be connected in this link gear before, rear wheel brake line and brake are bus, this link gear comprises body 1 with inner cavity chamber and the slide block 2 that can slide in this inner cavity chamber, before being somebody's turn to do, rear wheel

brake sleeve pipe

31,41 are fixed in this body 1 one ends side by side, and this brake is fixed in this body 1 other end to sleeve pipe 51, particularly, as shown in Figure 2, this body 1 is by the staving 12 of ccontaining this slide block 2 slidably, insertion type is installed on the loam cake 11 and the lower cover 13 at these staving 12 two ends and forms, this loam cake and lower cover and this staving form the inner cavity chamber of this body, this loam cake 11 is provided with a stepped hole 111, be convenient to brake brake when being positioned sleeve pipe 51 in this stepped hole 111 interior lines 52 activities are stretched in this staving 12, this lower cover 13 is provided with two stepped holes side by side, before being convenient to, rear wheel

brake sleeve pipe

31,41 when being positioned in the corresponding stepped hole before, rear wheel brake

interior lines

32,42 respectively activity stretch in this staving.

As Fig. 3, Fig. 4 and shown in Figure 5, this slide block 2 is provided with two knock holees 21 side by side, 22 and adjustment holes 25, before being somebody's turn to do, rear wheel brake

interior lines

32,42 fix two stop blocks 23 respectively after corresponding knock hole is passed in slide block 2 one side activities, 24, and to should front-wheel the knock hole of brake interior lines 32 be stepped hole 211, these preceding wheel brake interior lines 32 activities are passed behind this stepped hole and are worn this compression spring 27, fix corresponding stop block again, this compression spring 27 can be placed in these stepped hole 211 anchor rings, this brake is passed interior lines 52 this adjustment hole and is fixed in this adjustment hole by governing screw 26 from slide block 2 opposite sides, knock hole aperture that should rear wheel brake interior lines 42 is formed recess 221, be convenient to that corresponding stop block is positioned this recess 221 in this rear wheel brake.

Because these preceding wheel brake interior lines also activity wear compression spring, fix corresponding stop block again, can realize that like this trailing wheel is prior to front-wheel realization brake, and the front-wheel braking strength progressively increases, utilize this adjustment hole fit adjustment screw, can adjust brake like this displacement, the effect that the control brake is total, to should front-wheel the knock hole of brake interior lines be stepped hole, this compression spring can be placed in this stepped hole anchor ring, wheel brake was with respect to the delay degree of rear wheel brake before design helped controlling like this, and reaching whole brake has better buffering effect.
