Abstract
The utility model relates to a bicycle planet roller disc type brake, a brake clamp body of which comprises a clamp body(4), a brake lining(9), a spring leaf(8), an adjusting plug(10), a front push plate(12), a rear push plate(5)and a planet roller mechanism. The planet roller mechanism comprises a driving shaft(3), a roller(6), a torsion spring(2), a bolt(1)and an operating rod(7). The planet roller mechanism can generate a rolling function when the roller makes a planetary motion, so the bicycle planet roller disc type brake improves the clamping force and transmission efficiency of the brake clamp and improves the manufacturability.
Description
Technical field
The utility model relates to a kind of bicycle brake parts, especially with the mechanical disc-type brake of planetary roller reinforcement.
Background technology
At present, known bicycle mechanical plate disc brake is that brake clamp, brake disc and support three parts constitute.And brake clamp is crucial.Brake clamp is made up of caliper, brake lining, screw mechanism, joystick and spring.Screw mechanism makes brake lining produce gripping power to brake disc in caliper.
Practice shows: the gripping power that screw mechanism produced is the out of reach setting value all.Slip screw is mainly bad by touching, and surface pressure is excessive, and friction coefficient sharply raises, and galled spots has reduced driving efficiency, has reduced force increasing ratio.Contact stress has surpassed allowable value on the rolling of rolling screw, and rolling resistance increases, and force increasing ratio also descends greatly.In a word, under the bulk restriction, it is very difficult producing the setting gripping power with screw mechanism.Test shows: the various 1/3-1/2 that only reach desired value with its gripping power of brake clamp of spiral reinforcement.
Summary of the invention
Brake hypodynamic problem in order to solve present bicycle mechanical plate disc brake, the utility model provides a kind of planetary roller plate disc brake.
The technical scheme in the invention for solving the technical problem is: under caliper and brake lining permanence condition, substitute screw mechanism with planet rolling mechanism, the axis of this mechanism is parallel with brake lining.Concrete scheme: replace steel ball with roller, improve it and hold the sanction ability; Form planet motion with three row's rollers, change angle of obliquity and realize little range big-push force.So not only increase gripping power, also reduced difficulty of processing.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is brake clamp planetary roller mechanical work principle figure.
Fig. 2 is the longitudinal diagram of first kind of embodiment of brake clamp.
Fig. 3 is the birds-eye view of second kind of embodiment of drg.
Bolt in the drawings, 1; 2, torsion spring; 3, imput shaft; 4, caliper; 5, back board; 6, cylinder; 7, joystick; 8, spring leaf; 9, brake lining; 10, adjust spiral; 11, brake disc; 12, preceding push pedal.Remove brake disc (11) other pieces combination back and claim brake clamp.
The specific embodiment
Among Fig. 1, the planetary roller mechanism that dress is made of imput shaft (3) and three row's rollers (6) between caliper (4) and preceding push pedal (12).Initial position is that groove and caliper (4) axis on the imput shaft (3) is a angle.When imput shaft (3) when rotating in the direction of arrows, a angle diminishes, and the distance between preceding push pedal (12) and caliper (4) is diminished.Change three row's rollers (6) and do planet motion on one side along with changing a, also move in imput shaft (3) groove, then spend when enough when caliper (4), this moment, gripping power was more and more big.
Among Fig. 2, among the shown embodiment, order is loaded onto brake lining (9), spring leaf (8), adjuster plug (10), preceding push pedal (12), back board (5) and a cover planetary roller mechanism in the caliper (4): roller (6), imput shaft (3), torsion spring (2), joystick (7) and bolt (1).
Glancing impact, brake disc is pressed to preceding push pedal by brake lining (9) in swivel lever (7) planetary roller mechanism.
When loosening, torsion spring (2) resets planetary roller mechanism, and simultaneously spring leaf (8) two braking liners (9) are pushed open.
During adjustment,, also be the optimization point of gap value with adjuster plug (10) control gripping power size.
Fig. 3 is an another embodiment: caliper configuration two cover planetary roller mechanisms can obtain bigger lock torque.
Claims (3)
1, a kind of bicycle planet roller plate disc brake.It is to be made of pack in proper order in the caliper brake lining, spring leaf, adjuster plug, front and back board, imput shaft, roller, torsion spring and joystick machinery, it is characterized in that: constitute the planetary roller force-increasing mechanism by imput shaft, roller and front and back board.
2, drg according to claim 1 is characterized in that: single planetary roller mechanism that drives.
3, drg according to claim 1 is characterized in that: two drivings two are overlapped planetary roller mechanisms and are occupy in the caliper.
