Abstract
A single-plate two-way driving mechanical disk brake comprises a disk brake plate and a brake cramp, wherein the brake cramp is equipped with a jaw to hold the disk brake plate and a driving device. Both sides of the jaw are equipped with the left and right friction plates, between which is positioned with a return spring, with one friction plate positioned in the jaw arm and the other friction plate, connected with the driving device. The jaw on one side of the driving device is positioned with a steady support, wherein the driving device is equipped with a driving plate connected with the rocker arm. A wave-shaped spring is positioned between the steady support and the driving plate. A steel ball and a slide driving mechanism are arranged between the driving plate and the housing. A return spring is arranged between the steady support and the jaw arm. The two friction plates simultaneously clamp the two-way driving device of the disk brake plate, with the disk plate little deformed and the two friction plates uniformly worn for sound braking. The utility model is simple-structured, eliminates fault, saves manufacturing cost, good in the production and assembly specification process, and is capable of adjusting space without tools.
Description
Technical field
The utility model relates to the braking device of a kind of bicycle, tricycle, light-duty power car, particularly a kind of disc brake with bi-directional drive structure.
Background technique
In the prior art, in the domestic and international various mechanical type disc brake product, drive unit in its sincere caliper of stopping is owing to be subjected to the spoke of wheel and the too small influence of the useful space between the disc brake hull, mostly adopt the unidirectional drive structure, moments two friction plate before brake is not to contact disc simultaneously, but a slice friction plate is pressed in earlier on the disc end face, then the strength that forces disc to produce resiliently deformable or overcome the return spring that floats in the floating bracket under the active force of disc self rigidity makes caliper displacement vertically, until with just realize braking after the another side friction plate contact.So its brake disc is long-term work under the effect that is subjected to suitable axial force, disc is because under the effect of long-term frequent axial force, the end face run-out amount of aggravation disc, i.e. and disc rolling momentum strengthens, and friction plate occurs and rubs the disc phenomenon, produces and drags moment.People are by bike or during electric bicycle, the consumption that can strengthen manpower or electric energy, and other two friction plate abrasion degree differences influence the durability of disc brake.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of single-deck bi-directional drive mechanical type disc brake that assembly process process is good, have good braking effect of producing.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of single-deck bi-directional drive mechanical type disc brake, it comprises disc brake dish and brake binder, brake binder is provided with jaw and the drive unit that holds the disc brake dish, left and right sides friction plate assembly is equipped with on the jaw both sides, be provided with the return leaf spring between two friction plate assemblies, one of them friction plate assembly is contained in the tong arm, another friction plate assembly and drive unit join, the jaw place that is positioned at drive unit one side is provided with a fixed support, be characterized in: drive unit is provided with a drive plate that is connected with rocking arm, between fixed support and the drive plate wavy spring is housed, be provided with steel ball between drive plate and the housing, the slideway driving structure is equipped with Returnning spring between fixed support and the tong arm.
The technical problems to be solved in the utility model can also be achieved through the following technical solutions, and is provided with loose flange between drive plate and the friction plate assembly or is provided with convex portion and friction plate assembly joins at the end face of drive plate.
The technical problems to be solved in the utility model can also be achieved through the following technical solutions, and adds fixed tray between drive plate and housing, and steel ball, slideway driving structure are arranged between drive plate and the fixed tray.
The technical problems to be solved in the utility model can also be come by the following technical programs further to realize, is provided with spacing whirl-stop device between fixed support and the drive unit housing.
The utility model compared with prior art, its drive unit adopts a drive plate structure, between drive plate and the housing by steel ball or steel ball with have the slideway price fixing and realize driving, the friction plate that drive plate promotes loose flange and the friction plate that joins with it moves forward or the direct promotion of convex portion of drive plate is joined with it moves forward, simultaneously, drive plate acts on fixed support by wavy spring again, promoting drive unit and housing does oppositely to move, thereby it is mobile in opposite directions to drive another piece friction plate be positioned at tong arm, realizes that two friction plates embrace the bi-directional drive to the disc brake dish simultaneously.The disc distortion is little, and two friction plate abrasions are even, have good braking effect.Its structure is comparatively simple, has reduced fault, has saved fabricating cost, and it produces the good manufacturability of assembling, and the friction plate gap can directly be regulated by loose flange, can realize no instrument adjusting gap.
