Abstract
The utility model relates to an automatic adjusting arm for vehicle brake gap which belongs to the field of automobile braking component device, comprising an endless screw axis, a separation sleeve, a body case, a clutch, an endless screw, a worm-gear, a controlling arm, a rocking bar, a driving ring and a regulating ring. After braking and canceling the braking torque, the regulating ring can reset with the function of the spring when the interval between the friction plate of the automobile and the braking hub is over proof, and meanwhile, the ratchet of the end surface of the regulating ring can drive the clutch, the endless screw and the worm-gear in order to make the braking camshaft of the automobile rotating, so the braking interval can be adjusted. The utility model solves the problems that existing automobile brake adopts manpower adjusting, the adjusting occasion is hard to master, the adjusting interval is hard to reach the defined require, the left interval and the right interval is unequal, automobile sliding when brakes, and the security running of the automobile is harmed. The utility model is suitable for automatic adjusting the interval between various vehicle braking friction plates and the braking hub.
Description
Affiliated technical field:
The utility model relates to a kind of adjustment arm of vehicle brake gap, particularly a kind of arm for adjusting automobile brake clearance automatically.Belong to automobile brake accessory device field.
Background technique:
The braking device of automobile, the safety when being directly connected to automobile running.The break of automobile because of the wearing piece wearing and tearing cause wearing piece and the excesssive gap of braking hub, can cause braking ability to reduce in the course of the work, also directly influences the safety traffic of automobile.In order to address this problem, the adjustment arm generally all is housed on the break of automobile, the effect of adjusting arm is when wearing piece surpasses specified value with the gap of braking hub, its can reach specified value in adjusting play, guarantees the braking ability of break.And the adjustment arm that present automotive brake is adopted is to adopt the method for adjusting manually, all exist following defective, that is: on the one hand, be difficult to grasp adjustment opportunity, on the other hand, the gap of adjustment is difficult to reach the requirement of regulation, often produce the phenomenon that gap, the left and right sides is unequal, run the limit when braking, the safety traffic of harm automobile, therefore, national regulation is eliminated this adjustment arm.
Summary of the invention:
The purpose of this utility model is: provide a kind of and can adjust wearing piece and the gap of braking between the hub automatically, and can make gap, the left and right sides equal fully, very safe arm for adjusting automobile brake clearance automatically when making the automobile running brake.
The utility model is to realize above-mentioned purpose by following technical solution:
This arm for adjusting automobile brake clearance automatically is made of worm-wheel shaft, separation sleeve, body shell, clutch, worm screw, worm gear, control arm, rocking bar, driving ring and regulation and control ring, the body shell links by the pneumatic link rod of bolt and braking automobile, be fixed with a worm shaft by separation sleeve in the body shell, it is characterized in that: the end by separation sleeve of worm shaft is equipped with a clutch, the centre is shaped on worm screw, be engaged with a worm gear on the worm screw, the end of worm gear is with a driving ring, the rocking bar and the control arm that drive the rotation of regulation and control ring are housed on the driving ring, are shaped on ratchet on the end face of regulation and control ring.
The utility model compared with prior art has following beneficial effect:
Solve existing vehicle brake gap and adopted artificial the adjustment, be difficult to grasp adjustment opportunity and the unequal problem in gap, the adjusted left and right sides.Automatic adjusting play in the time of surpassing specified value in the gap of wearing piece and braking hub, and the maintenance forever of gap, the adjusted left and right sides is equal, makes automobile safe especially when travelling brake.
Description of drawings:
Fig. 1 is the plan view of arm for adjusting automobile brake clearance automatically;
Fig. 2 is the plan view of arm for adjusting automobile brake clearance automatically.
Among the figure: 1. worm shaft, 2. separation sleeve, 3. body shell, 4. clutch, 5. worm screw, 6. worm gear, 7. control arm, 8. rocking bar, 9. driving ring, 10. regulation and control ring.
Embodiment:
This arm for adjusting automobile brake clearance automatically is made of worm shaft (1), separation sleeve (2), body shell (3), clutch (4), worm screw (5), worm gear (6), control arm (7), rocking bar (8), driving ring (9), regulation and control rings (10).Automatically the body shell (3) of adjustment arm links by the pneumatic link rod of bolt and braking automobile, and the other end is by the internal spline and the interlock of brake cam of automobile axle of worm gear (6).Control arm (7) is fixed on the axle housing.Before the use, separation sleeve on the arm for adjusting automobile brake clearance automatically after installing (2) is pressed, the clutch (4) on the worm shaft (1) is left, adjust the position of regulation and control ring (10) end face ratchet and clutch (14), unclamp separation sleeve (2) again, clutch (4) is closed up.During automobile brake, ratchet by regulation and control ring (10) end face drives clutch (4), gap between wearing piece and braking hub just often, the ratchet and the rotation between the clutch (4) of regulation and control ring (10) end face do not surpass a tooth, when returning after the cancellation braking, regulation and control rings (10) do not have with clutch (4) and relatively rotate, and clutch (4) does not drive worm screw (5) and worm gear (6), the brake camshaft of automobile does not rotate, and does not carry out the gap adjustment between wearing piece and the braking hub.When the gap between wearing piece and the braking hub is overproof, the ratchet and the rotation between the clutch (4) of regulation and control ring (10) end face surpass a tooth, regulation and control rings (10) drive clutch (4) and rotate an angle when returning after the cancellation braking, clutch (4) drives worm screw (5) and worm gear (6) simultaneously, make angle of brake camshaft rotation of automobile, and reach the purpose of automatic adjustment brake clearance.
