Description

Bicycle dished brake

Technical field

The utility model relates to the parts of Electrical Bicycle, specifically a kind of mechanical Bicycle dished brake.

Background technology

Bicycle and Electrical Bicycle are the traffic means of transport of China's owning amount maximum, and in order easily to control and to regulate the speed of advancing and promptly realizing stopping, one of the parts that are absolutely necessary brake.Past brake commonly used is with the brake backguy, the drag friction piece is pressed to the pull clamp structure of wheel rim, when the steel ring invar silk of bicycle is adjusted when unbalanced, two lateral surfaces can swing when rolling, and cause the applying of friction shoe and wheel rim intermittent, promptly produce and skid, braking effect is descended.The brake of this type of form is at present substituted by a kind of more failure-free disc brake just gradually, its version is to consist predominantly of a brake disc and the disc brake body that is fixedly connected on the vehicle frame that is fixed on the wheel, in the disc brake body, be provided with one can ccontaining brake disc opening, be equipped with bremsbelage respectively in two side through hole of this opening, wherein the bremsbelage of a side also is connected with a bremsbelage penetrating mechanism that is contained in the brake body through-holes, this penetrating mechanism is by upper ejector pin, lower push rod, the pushing and pressing pearl, returning spring, the solid seat of spring constitutes, upper ejector pin is connecting the movable arm that can scratch commentaries on classics with respect to body, when movable arm is scratched commentaries on classics by the backguy pulling, penetrating mechanism can be with the friction lining ejection to brake disc, to reach the purpose of deceleration.Since upper ejector pin when being reversed the upper ejector pin side arm be local the contact with the containing hole arm contact of body, the uneven wearing and tearing of therefore easy formation, thus cause whole penetrating mechanism axis and containing hole axis not parallel.

The utility model content

The Bicycle dished brake that the purpose of this utility model is to provide a kind of movable arm, push rod to rotate flexibly and to reset, the body containing hole is difficult for localized wear.

The concrete structure of realizing the technical solution of the utility model is such: it includes body, the fixed arm that extends to form on the body, the movable arm that pivots of body relatively, supply the ccontaining opening of brake disc on the body, the ccontaining through hole vertical with opening, the ccontaining bremsbelage of difference in opening two side through hole, ccontaining by upper ejector pin in this end through hole of movable arm, lower push rod, the pushing and pressing pearl, returning spring, the bremsbelage top-pressure mechanism that the spring check screw is constituted, the bremsbelage plus-minus screw of the body other end, the extended connection lug in body outer rim both sides, bremsbelage is adsorbed by magnetic, the extended connection lug in brake body both sides also mates the connecting plate that is connected with the Electrical Bicycle frame, and outside the upper ejector pin of bremsbelage top-pressure mechanism, also be set with the sliding support pad, this annular surface has annular groove, be used to store lubricating oil, improve the contact condition of upper ejector pin outer wall and the ccontaining internal face of body; In order to reduce sliding support pad friction force, the sliding support pad can be provided with stack use more than two, can be that section is circular hoop with being set as of being clipped in the middle, the annular groove that has on the size of this circular section hoop and the pad is complementary, and can store more lubricating oil in the annular groove; Also having these sliding support pads can be the antifriction material system that handle through antifriction on plastics, graphite or surface.

Bicycle dished brake of the present utility model, between the containing hole of the upper ejector pin of bremsbelage top-pressure mechanism and the body that brakes, sliding support pad and circular section hoop have been added, and the material of reduce friction power and self-lubricating is made, long-term local action to the containing hole of brake body when both having alleviated movable arm and reversing the back and drive upper ejector pin and rotate causes wearing and tearing, can not increase the friction force when trackslipping again, and improve simple in structure, handling ease, easy to use, effective.

The specific embodiment

Below in conjunction with embodiment the utility model is further described, following each embodiment only is used to illustrate the technical solution of the utility model, but to not restriction of the utility model.

Embodiment one

As shown in fig. 1, Bicycle dished brake of the present utility model is by

disc brake body

9a, 9b, the fixed arm 9c that extends to form on the body 9a, the movable arm 2 that pivots of body relatively, body 9a goes up for the ccontaining opening 9d of brake disc, the ccontaining through hole 9d vertical with opening, the bremsbelage 18 that the opening both sides are provided with respectively, 19, bremsbelage 18, the 19th, be similar to table tennis racket shaped, the position of protruding is handle portion, ccontaining top-pressure mechanism is by upper ejector pin 15 in the through hole 9d of body 9a, lower push rod 13, pushing and pressing pearl 14, be sleeved on the returning spring 16 on the upper ejector pin 15, spring check screw 17 is constituted, its upper ejector pin 15 is placed in the returning spring 16, be to be clipped in successively, pushing and pressing pearl 14 between lower push rod, lower push rod 13, lower push rod 13 outer suit sliding support pads 12, pull bar check screw 1 is connected with lower push rod 13, the fixed arm 9c of body 9a should end face movable arm 2 be connected with lower push rod 13 in the through hole 9d with pull bar check screw 1 and lower push rod 13, drag friction car sheet 18 is abutted on the spring check screw 17 by magnetic absorption, among the through hole 9d of the other end of body 9b relative fixed arm 9c, drag friction car sheet 19 dorsal parts are equipped with plus-minus screw 21,22nd, tie bolt, the 23rd, pin.From figure, it can also be seen that, part 4 is flat shims, part 5 is clamp screws, part 6 is backguy setting nuts, part 7 is backguy governing screw, and part 8 is connecting plate governing screw, and respectively there is extended connection lug 9e both sides on brake body 9a, connection screw on this connection lug 9e is slotted hole as shown in Figure 1, so that carry out the adjustment of position when connecting.

Certainly, be located in the ccontaining through hole 9d of body 9a, but be set on the lower push rod 13 sliding support pad 12 also as shown in Figure 2, it is by the flat shim 1 that has annular groove on two plate planes and the hoop 2 of the circular section in the middle of being installed in is constituted.Also can be so as shown in Figure 3 in addition, be formed by stacking by three flat shims that have an annular groove that is used to store lubricating oil.The material that also can be such sliding support pad 12 as shown in Figure 4 is material of handling through antifriction with plastics, graphite, surface.

During use, brake disc is fixed on the wheel, brake body 1 is connected on the vehicle frame, adjusts the parallelism of brake disc and bremsbelage, and the brake backguy gets final product in the connection.
