Abstract
A bicycle straight-pulling rolling inclined wedge force increasing disc brake is provided, which comprises a brake liner, a front bearing block, a passive inclined wedge, an active inclined wedge, a rolling needle, a maintenance frame, a spring, and a brake disc arranged in a clippers body in turn. The rolling inclined wedge force increasing mechanism comprises a passive inclined wedge, an active inclined wedge, a rolling needle and a maintenance frame. The contact of a plurality of lines of ribs lowers the contact stress, enhances the efficiency, and ensures the holding forces, thus meeting the safety requirement. The utility model has the advantages of concise straight-pulling structure and easy production.
Description
The new technical field that belongs to
The utility model relates to a kind of bicycle brake parts, especially with the mechanical type plate disc brake of vertical pulling rolling inclined wedge augmenting.
Background technology
At present, known bicycle mechanical formula plate disc brake, it is to be made of caliper, brake lining, active spiral, passive spiral, steel ball, fork and brake disc.The gripping power of drg depends on the driving efficiency of the screw pair that is made of master, passive spiral and steel ball.Plug helix engineering factor in this screw pair requires very strict, and difficulty is very big on the technology, the out of reach requirement, and contact stress can surpass allowable value, and driving efficiency is low, and force increasing ratio descends, gripping power out of reach anticipated value.It is very high to reach the requirement cost, popularizes difficulty.
Summary of the invention
Gripping power in order to ensure setting reduces its difficulty of processing, and the utility model provides a kind of Straight pull rolling inclined wedge augmenting plate disc brake.
The technical scheme that its technical matters that solves the utility model adopts is: the two rolling wedges of direct pull are obtained gripping power.Constitute Wedge mechanism by active wedge, passive wedge, needle roller and retainer, initiatively wedge two driving surfaces have two row's needle rollers.Be many line contacts between pair, increase its load-carrying capacity, driving efficiency is guaranteed.Wedge processing is simple.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is a longitudinal sectional drawing of the present utility model.
Fig. 2 is the I-I transverse cross-sectional view of Fig. 1.
1. calipers among the figure, 2. brake disc, 3. brake lining is 4. before held piece, 5. wedge initiatively, 6. spring, 7. needle roller, 8. retainer, 9. passive wedge.
The specific embodiment
Among Fig. 1, brake disc (2) is fixed on the wheel wheel hub.The preceding passive wedge of piece (4) (9) that holds of brake lining (3) is packed into earlier in the caliper (1).Spring (6) is packed into earlier initiatively in the wedge (5), and needle roller (7) installs with retainer (8), refills in the caliper (1), and this moment, assembly claimed brake clamp, and it is to be fixed on the vehicle frame.
Among Fig. 2, glancing impact, backguy pulling initiatively wedge (5) is downward, left and right sides needle roller row rolls downwards (7) (8) thereupon, the right side is against on caliper (1) rear wall, and the left side promotes passive wedge (9) left, by preceding holding piece (4) brake lining (3) is pressed to brake disc (2) enforcement braking.
When loosening, locking backguy, initiatively wedge (5) resets under spring (6) effect, and drives needle roller row (7) (8), and passive wedge (9) resets.
Claims (3)
1, a kind of bicycle disk brake, it be by order in the caliper pack into brake lining, initiatively spiral base, passive spiral base, shake wedge, roller, steel ball, fork and brake disc and constitute, it is characterized in that: its force-increasing mechanism is the roller screw pair.
2, drg according to claim 1 is characterized in that: in the screw pair initiatively spiral base with shake wedge and constitute initiatively spiral, passive spiral base with shake wedge and constitute passive spiral, rolling body is a roller.
3, drg according to claim 1 is characterized in that: radially imput shaft, roller and the passive spiral of circular groove constitute screw pair by there being three.
