Abstract
A two-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. A steady support is positioned on the jaw on one side of the driving device, which is equipped with a big driving plate connected with the rocker arm and a small driving plate connected with the back of the friction plate component. The driving face of the big driving plate is positioned with an internal and an external driving slide, and the driving slide on the driving face of the small driving plate engages with the internal driving slide of the big driving plate by the steel ball. The steady support is equipped with the driving face engaged with the external driving slide of the big driving plate, wherein the driving face is equipped with the ball socket or slide engaged with the external driving slide of the big driving plate by the steel ball. The return spring is positioned between the steady support and the housing or between the steady support and the caliper arm. The two-layer driving slide of the big driving plate is in the same plane, simple in the specification process, the position between the internal slide and the external slide easily determined and the assembly not being over positioned, with sound brake.
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 double plate bi-directional drive mechanical type disc brake with good braking effect.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of double plate 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, is characterized in: the little drive plate that drive unit is provided with a big drive plate that is connected with rocking arm and joins with the back side of friction plate assembly; The drive surface of big drive plate is provided with inside and outside two-layer driving slideway, and the driving slideway on the drive surface of little drive plate drives slideway by steel ball with the internal layer of big drive plate and cooperates; Fixed support is provided with the drive surface that cooperates with the outer driving of big drive plate slideway, and drive surface is provided with by steel ball and big drive plate skin and drives ball-and-socket or the slideway that slideway cooperates; Be provided with Returnning spring between fixed support and the housing or between fixed support and tong arm.
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 pad between the back side of big drive plate and the housing.
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 little steel ball between the back side of big drive plate and the housing.
The utility model compared with prior art, inside and outside two-layer driving slideway is set on the driving card of big drive plate, the internal layer slideway promotes little drive plate to the extrapolation friction plate by steel ball, simultaneously, outer slideway acts on fixed support by steel ball, then promote drive unit and housing and oppositely move, move in opposite directions, realize the bidirectional-movement that two friction plates move to the disc brake dish simultaneously thereby drive another piece friction plate that is positioned at tong arm.Bilayer on the big drive plate drives slideway on same plane, and preparation process is simple, and the position between the interior external slideway guarantees that well the problem of location can not appear in assembling.Big drive plate does not have axial motion, when therefore the rocking arm that joins with big drive plate rotates, sinkage can not occur.The disc distortion is little, and two friction plate abrasions are even, prolonged the working life of friction plate, have good braking effect simultaneously.
