Below in conjunction with accompanying drawing concrete structure of the present utility model is further described:

The utility model comprises braking chassis 8, and braking is fixed with spline housing 7 on the chassis 8, is brake disc 14 outside the spline housing 7; Brake disc 14 is fixed in transmission flower cover 18, be aligned in sequence with friction disk 16 on the spline housing 7 in brake disc 14 outsides, end lock collar 17, be aligned in sequence with the platen 12 that rubs, pressure disk 10, corrugated hydraulic chamber 9 on the spline housing 7 of the inboard of brake disc 14, corrugated hydraulic chamber 9 links to each other with oil hydraulic cylinder 5.

Be to strengthen the working life of friction disk 16, the platen 12 that rubs, can be in friction disk 16 inboards, the inboard of the platen 12 that rubs is respectively arranged with liner 15, liner 13.

Friction disk 16 is fixed in by lock screw 20 and ends on the lock collar 17; Spline housing 7 outer ends are provided with retaining projection 21.

For the fortuitous event that prevents the utility model brake failure takes place, can be provided with trigger 3, trigger 3 comprises body 45, has movably pull bar 34 on the body 45, one end of pull bar 34 has link stopper 33, the other end of pull bar 34 is connected with dashboard 11 by drag-line 6, and the drift 24 on the dashboard 11 contacts by the cushion block 26 of roller 25 with the liner 27 on the platen 12 that rubs, and is Returnning spring 23 between dashboard 11 and the braking chassis 8; One side of the torque arm 28 on 45 of the bodies is connected with the Returnning spring on the body 45 30, torque arm 28 opposite sides are connected with the balladeur train on the pull bar 34 35 by bearing pin 31 in 34 chutes 32 of the pull bar on the push rod 29, having on the waist axle 42 of body 45 can be with the stopping-receding bench 44 contacted hook 41 of pull bar 34, drift 37 on the afterbody of hook 41 can contact with the roller 38 on the movable clamp 40 on the balladeur train 35, the front portion of hook 41 is provided with Returnning spring 43, so that hook 41 contacts with pull bar 34 all the time.Move position for ease of drift 37, and drift 37 afterbodys are provided with adjusts screw 36.

When using the utility model, the utility model is fixed between the wheel net 19 and wheel hub 22 of wheel, oil hydraulic cylinder 5 is by braking overall pump 4, connecting rod 2, continuous with foot treadle 1.

A regular event circulation of narration the utility model break below.

In the time of on forcing in foot treadle 1, foot treadle 1 is by connecting rod 2, braking overall pump 4, oil cylinder 5,9 pairs of pressure disk 10 application of forces of corrugated hydraulic chamber, pressure disk 10 by the 12 pairs of brake discs 14 of platen that rub, friction disk 16, end lock collar 17 application of forces, because the projection 21 of spline housing 7 stops, brake disc 14 is tightly clamped by friction disk 16, the platen 12 that rubs, and has promptly implemented braking action of the present utility model; When no longer to foot treadle 1 application of force, corrugated hydraulic chamber 9 automatically resets, and brake disc 14 is also no longer clamped, has promptly eliminated braking action.

The course of action of trigger 3: torque arm 28 is applied pulling force, push rod 29 makes balladeur train 35 to link stopper 33, link stopper 33 makes that pull bar 34 moves, the head of hook 41 is fallen stopping-receding bench 44 places, and the drift 37 of the afterbody of hook 41 contacts with the roller on the clamp 40 38, at this moment, drag-line 6 is tightened up, balladeur train 35 resets under return spring 30 effects, and drag-line 6 affects dashboard 11 to overcome the power of Returnning spring 23, and dashboard 11 is rotated, roller 25 is in drift 24 lowers, and liner 27 different braking dishes 14 contact; In case during the utility model brake failure, or when needing Parking, torque arm 28 is applied pulling force once more, 29 pairs of balladeur train 35 application of forces of push rod, roller 38 on the clamp 40 can not be swung again, and roller 38 advances along drift 37, presses down the afterbody of hook 41, the front end of hook 41 overcomes Returnning spring 43 effects and is lifted, leaves stopping-receding bench 44, drag-line 6 no longer is tightened up, and rotates at Returnning spring 23 effect lower-pilot dishes 11, and roller 25 is in drift 24 eminences, liner 27 contacts with brake disc 14, just can play braking action.
