Abstract
The utility model relates to a kind of Bicycle dished brake device, and its structure comprises brake body, pull handle, hold-down arm, u-shaped spring, brake shoe brake cheek, pull back spring.Brake body is divided into left brake body, right brake body, and is connected by bolt, and brake shoe brake cheek is also divided into left brake shoe brake cheek, right braking hoof, and two brake shoe brake cheek middle inside have cuboid groove.Left and right brake shoe brake cheek is loaded on left and right respectively and stops vehicle body, be embedded in the groove of left and right brake shoe brake cheek about u-shaped spring, pull back spring two ends connect hold-down arm and pull handle respectively, fixed pulley pin or other connection mode are determined and hold-down arm, and pull handle can freely rotate an angle promotion brake shoe brake cheek around eccentric pin shaft and move to disc under the pulling of brake cable.The utility model structure is simple, and lower to requirement on machining accuracy, materials are few, under the prerequisite meeting braking effect, reduce cost.
Description
Technical field
The utility model relates to a kind of Bicycle dished brake device, belongs to machinery manufacturing technology field.Background technology
Current market has upper common braking binder of bicycle to have friction glue formula or disc brake type.Friction glue formula is with low cost but performance is good not, often occurs the situation that left and right brake pads wear inequality causes braking quality decline even malfunctioning.Disc brake type function admirable, travelling comfort when braking effect and brake is better, but complex structure, the requirement on machining accuracy of some parts is high, and materials are more, and cost is higher.
Summary of the invention
The present inventor is through thinking and research, and design has improved out a kind of brand new Bicycle dished brake device, well solves current technology and the incompatible problem of cost.The technical solution of the utility model is as follows: Bicycle dished brake device comprises brake body, pull handle, hold-down arm, u-shaped spring, brake shoe brake cheek, pull back spring.Brake body is divided into left brake body, right brake body, and brake shoe brake cheek is also divided into left brake shoe brake cheek, right braking hoof, and two brake shoe brake cheek middle inside have cuboid groove.Mounting means left and right brake shoe brake cheek is loaded on respectively left and right to stop vehicle body, and u-shaped spring is embedded in the groove of left and right brake shoe brake cheek, and pull back spring two ends connect hold-down arm and pull handle respectively, and fixed pulley pin or other connection mode are arranged in hold-down arm.Pull handle head is eccentric structure, and this eccentric structure contacts with brake shoe brake cheek, is provided with the fixed pulley changing brake cable direction, is provided with the pull back spring making pull handle return between pull handle and hold-down arm in support arm head hollow structure.The above pull handle pin is connected on left brake body, and pull handle head and left brake shoe brake cheek are close together, and pull handle can rotate relative to pull handle head eccentric shaft.
The beneficial effect of the utility model Bicycle dished brake device is: overcome traditional disc brake complex structure, some component processing accuracy requirements are higher, materials are many, the shortcoming that cost is high, under the prerequisite meeting braking effect, achieve again structure simple, economic benefit with low cost, be applicable to extensively promoting the use of.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the utility model Bicycle dished brake device.
Mark in figure: 1. fixed pulley, 2. brake cable, 3. pull back spring, 4. pull handle, 5. pull handle head, 6. left brake body, 7. left brake shoe brake cheek, 8. disc, 9. right braking hoof, 10. right brake body, 11.u type spring, 12. hold-down arms.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature more easily and be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.As shown in Figure 1, Bicycle dished brake device, comprises left brake body (6), right brake body (10), left brake shoe brake cheek (7), right braking hoof (9), hold-down arm (12), pull handle (4).Left brake body (6) is connected by 2 bolts with right brake body (10); U-shaped spring (11) is embedded in the middle of left brake shoe brake cheek and right braking hoof; Fixed pulley (1) is arranged in the hollow structure of hold-down arm (12) head by pin: pull back spring (3) two ends connect pull handle (4) and hold-down arm (12) respectively.The principle of work of above-mentioned disc brake is: brake cable (2) is walked around fixed pulley (1) and is connected with pull handle (4) through pull back spring.The object of fixed pulley 1 changes pulling direction and the cliding friction between traditional brake cable and hold-down arm being changed over the friction of rolling compared with less friction of brake cable 2; When brake cable (2) is tightened up, pull handle (4) can rotate an angle and compresses pull back spring (3) by the bearing pin on pull handle head (5), because pull handle head (5) is eccentric structure, when brake cable (2) when pulled, left brake shoe brake cheek moves closer to until compress disc (8) to complete braking.When after releasing of brake line, pull handle can pop into position by compacted pull back spring, simultaneously left brake shoe brake cheek (7) and right braking hoof (9) return under the effect of u-shaped spring (11), thus left and right brake shoe brake cheek is separated with disc.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any change of obtaining without creative work or replace all should be covered by this utility model protection domain within; therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
Claims (1)
