Description

Regulating structure for brake

The utility model relates to a kind of brake shoes and adjusts structure, particularly relates to the brake shoes structure that a kind of brake shoes can be done 360 ° of comprehensive adjustment.

At present, in the general stress-relieving activity, with most popular by bike, except body-building, outside the motion, it also has to park and does not take up space, can not produce the air-polluting advantage, bicycle is of a great variety, as the car of climbing the mountain, the car etc. of competing for speed, moulding, different its interest of function, yet, all bicycles have a common ground, promptly must possess brake, brake modes is that the braking brake piece contacts with bicycle flange and stops and stop, when bicycle of assembly, the adjustment of brake shoes position is considerable, because bicycle flange roughly has two kinds on V-type U type, effectively contacts for brake shoes is braked with wheel rim, brake shoes must be adjusted to the appropriate location, brake shoes is because frequent friction and loss gradually, and brake shoes is subjected to the wheel revolutions effect of inertia when contacting with wheel rim, and can depart from slightly, make brake shoes often can't do contacting of maximum area with wheel rim, therefore, the rider often must be at the situation of driving, the brake shoes position is done suitably to adjust, can safety and comfort drive is so brake shoes is adjusted structure by becoming dealer's active research, one of target of development.

See also shown in Figure 1, be that a kind of brake shoes is in the past adjusted structure, brake shoes 1 is fixed in a bar 2,2 of bars are placed through a sleeve column 3, establish perforate 48 on the brake arm 4, and fix a tab 5 in perforate 48, offer a slotted hole 58 on the tab 5, sleeve column 3 is nested with a bevelled washer 6, and passes the slotted hole 58 of tab 5, is locked on the brake arm 4 with nut 7 Passscheibens etc., can be by on sleeve column 3 be in slotted hole 58, move down, to adjust brake shoes 1 upright position, in addition, can be by adjusting the position of bevelled washer 6, be offset radian and adjust brake shoes 1, certainly, adjust the position of bar 2 in sleeve column 3, then can do the adjustment of brake shoes 1 front and back position.

Yet brake shoes adjustment structure still had following shortcoming in the past:

One: must make tab 5, and it is mounted on the brake arm 4, processing procedure is comparatively complicated.

Its two: bevelled washer 6 coagulates in fixed elevation own, can not do omnibearing radian adjustment, usually brake shoes 1 can't be adjusted to the appropriate location.

Main purpose of the present utility model is to provide a kind of brake shoes of doing 360 ° of comprehensive adjustment to adjust structure.

Characteristics of the present utility model are: make the bottom be the adjustment piece of indent circular conical surface, move on cone shape spacer and adjust, make brake shoes can do comprehensive adjustment, do the most effective the contact to adjust brake shoes with wheel rim.

Adjust structure according to a kind of brake shoes of the present utility model, mainly be that the bar that the brake shoes back side sets firmly is placed through in the perforation of a sleeve column one end, place one on the sleeve column and adjust a piece and a spacer, pass the perforate of brake arm again, and be nested with a pad and a positioning block, the sleeve column other end is provided with screw thread fit one nut and is locked in brake arm, it is coniform that spacer is, central authorities are provided with through hole, its bottom is for the plane and fit in brake arm, adjusts the circular conical surface of piece and spacer and fits, and is cylinder, central authorities are provided with a through hole, and itself and spacer joint place are the indent circular conical surfaces that is suitable radian.

Below by most preferred embodiment and accompanying drawing brake shoes of the present utility model is adjusted structure and be elaborated, in the accompanying drawing:

Fig. 1 is the exploded perspective view of the structure of brake shoes adjustment in the past.

Fig. 2 is the exploded perspective view of the utility model first preferred embodiment.

Fig. 3 is the combination cross-sectional schematic of the utility model first preferred embodiment.

Fig. 4 is the use scheme drawing of the utility model first preferred embodiment.

Fig. 5 is another use scheme drawing of the utility model first preferred embodiment.

Fig. 6 is the combination scheme drawing of the utility model second preferred embodiment.

Please consult Fig. 2 simultaneously, shown in 3, the utility model brake shoes is adjusted structure first preferred embodiment, mainly be to be installed on the brake arm 10, brake arm 10 is installed on bicycle flange 20(and sees also Fig. 4) both sides, be provided with perforate 11, it is the cylinder body of rod that brake shoes 30 back sides set firmly a bar 31, one sleeve columns 40, one end tool column cap 41, column cap 41 is provided with perforation 411 and places for bar 31, sleeve column 40 end in addition is provided with external screw thread 42, puts with a nut 43 locks, and sleeve column 40 passes one and adjusts a piece 60 and a spacer 50, pass the perforate 11 of brake arm 10 again, be nested with a pad 70 and a positioning block 80 at last, cooperate aforementioned nut 43 to be locked in brake arm 10, wherein:

Spacer 50 is coniform, and central authorities are provided with perforation 51, and its bottom is for the plane and fit in brake arm 10, and the top then is a circular conical surface 52.

Adjust piece 60, fit with the circular conical surface 52 of spacer 50, be cylinder, central authorities are provided with a through hole 61, and 41 week of the column cap footpath of through hole 61 apertures and sleeve column 40 is suitable, and its bottom surface and spacer 50 joint places are the indent circular conical surfaces 62 that are suitable radian.

Pad 70 also is coniform, and the bottom surface is that the plane fits in brake arm 10, and end face then is a circular conical surface 71.

Locating piece 80, bottom surface are that circular conical surface 81 is fitted with the circular conical surface 71 of pad 70.

Above-mentioned is basic structure of the present utility model and relevant position thereof, use situation as for it, see also shown in Figure 4, if the contact surface of brake shoes 30 is vertical wheel rims 20, then the rotator inertia because of wheel rim 20 influences, brake shoes 30 can't contact with wheel rim 20, at this moment after being subjected to brake arm 10 brakings fully, it is adjustable loose nut 43, running fix sheet 50 screws nut 43 again to required angle again, adjusts 20 one-tenth appropriate tilt angles of brake shoes 30 and wheel rim, state as shown in Figure 5, during brake, brake shoes 30 is contacted fully with wheel rim 20, make drag with actv..

Please continue to consult shown in Figure 5, on the circular conical surface 51 of spacer 50, move adjustment owing to adjust piece 60 with its indent circular conical surface 62, brake shoes 30 can be done 360 ° of comprehensive adjustment, also be that brake shoes 30 is looked the position of adjusting piece 60 and spacer 50 applyings, and present the skew of different radians, in addition, pad 70 also fits with circular conical surface 71,81 with locating piece 80, cooperate the adjustment of aforementioned adjustment piece 60 and spacer 50, can rapidly brake shoes 30 be adjusted to the location.

Seeing also shown in Figure 6ly, is the utility model second preferred embodiment, its with aforementioned different be in: brake arm 90 is with original coniform pad one forging moulding, forms a cone part 91, so can simplify load module, processing procedure.

Certainly, among the aforesaid embodiment of the utility model, the perforate 11 of brake arm 10 can be done the adjustment in upper and lower orientation for brake shoes 30, and 31 of bars move in the perforation 411 of sleeve column 40, and adjust the forward and backward position of brake shoes 30.

The utlity model has following advantage:

One: need not make the tab such as in the past in addition, save the trouble that is installed on the brake arm 10, simplify processing procedure, simple installation.

Its two: by adjusting matching of piece 60 and spacer 50 circular conical surfaces 61,52, make brake shoes can do 360 ° comprehensive adjustment, and the skew of different radians is arranged, make contacting that brake shoes 30 can be appropriate with wheel rim 20, do actv. brake, prolong brake shoes service life.

In sum, brake shoes of the present utility model is adjusted structure, really is the structure of a novelty, practicality.
