Above-mentioned braking adjusting arm adopts traditional worm and gear, although convenient use and safe and reliable, complex structure, maintenance is large, cost is higher, is not suitable for applying.
CN202284622 U discloses a kind of braking adjusting-arm of Linear locking, comprise the worm shaft that cooperates with adjustment mounting hole on the braking adjusting-arm body, and worm gear and worm screw, worm screw is provided with slotted eye connecting worm axle along central axis, adjust mounting hole and be provided with gear ring along the inwall circumference, be provided with steel ball between the corresponding shrinkage pool on gear ring and the worm shaft, one section on the nut of worm shaft is provided with central shaft hole, be provided with successively from inside to outside spring, center steel ball, adjusting screw rod in the central shaft hole, adjusting screw rod is threaded with central shaft hole; Described adjusting screw rod enters top outer circumferential walls in the central shaft hole when cooperating with steel ball, and steel ball ejects and the gear ring interference fit.The present invention is by interference fit or the Spielpassung of adjusting screw rod contact steel ball control steel ball and gear ring.
The braking adjusting-arm complex structure that CN202284622 U proposes, working life is weak point and maintenance trouble.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is that the skidding that provides a kind of realization brake brake clearance simple in structure, with low cost, that maintenance is little, safety and environmental protection is practical to regulate is adjusted arm.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of skidding is adjusted arm, comprise the adjustment arm armed lever that links to each other with the air chamber push rod and the denticle with gear ring that is connected with camshaft, described adjustment arm armed lever has attachment hole, described denticle with can be flexibly connected around the adjustment arm armed lever that the attachment hole axis rotates, described denticle has one can drive the regulating arm that gear ring rotates around the attachment hole axis, regulating arm be provided with one with adjust controlling mechanism that the arm armed lever is connected, that can drive the regulating arm rotation and reset.
Above-mentioned skidding is adjusted arm, and described denticle is fixed on by back-up ring and adjusts on the arm armed lever.
Above-mentioned skidding is adjusted arm, and described controlling mechanism is by being located at the joint adjusted on the arm armed lever, passing the double-screw bolt that regulating arm is fixedly connected with joint and the adjusting nut be located on the double-screw bolt outside the regulating arm forms.
Above-mentioned skidding is adjusted arm, it is characterized in that: be provided with one between described joint or adjustment arm armed lever and the regulating arm and drive the Returnning spring that regulating arm resets.
The advantage that skidding of the present invention is adjusted arm is: simple in structure, the cost of production simple process is easy to regulate, and has greatly saved cost, makes its great market competitiveness and applicability.Adjusting the arm armed lever is foundry goods, the high processing that is easy to simple in structure of intensity; Denticle is the firm modulation treatment of alloy, and intensity is high, has improved greatly the performance of adjusting arm; Bolt structure is simple, is easily damaged parts, and the rear replacing that is damaged is simple.Adjust the angle that relatively rotates of arm armed lever and denticle by adopting double-screw bolt and adjusting bolt to finely tune, come regulating brake skidding gap, easy to adjust, Returnning spring both can be realized reset function, also can realize the relative position between fixed support denticle and the adjustment arm armed lever, realize the adaptation of free adjusting and braking, this novel adjustment arm of cost aspect is because simple in structure, greatly reduce cost, and can keep in repair, maintenance expenses simple in structure is extremely low, can realize recycling, avoided waste, safety and environmental protection is applicable.
