Description
The utility model relates to a kind of braking automobile gap automatic adjusting mechanism technical field.
The domestic automobile brake is adjusted arm and is not generally had automatic elimination gap function, have only the arm of adjustment, cover plate and worm screw, worm gear, when brake block is worn the back with spider creep when big or driver when feeling that brake is not agile, just go to the artificial commentaries on classics worm screw gap of adjusting, can not eliminate the gap at any time, so just exist personal factor and the hidden danger of hiding, it is safe and reliable to influence braking automobile.As the patent No. is that the Chinese patent " automobile pressure regulating type self-actuating brake valve " of 94229274.X discloses a kind of braking automobile safety installations, it is by by forming valve body at the bottom of the valve gap valve, valve body is provided with the brake suction port, the brake air outlet, gas receiver outlet and inflating pump import, piston is set in the valve body, B, O-ring seals, spring, jump ring, one-way valves etc. are formed three air chambers, the pressure regulation pad is set at the bottom of the valve, voltage regulation screw, this valve is connected gas receiver, though it is sensitive that it has brake, safe and reliable advantage, but exist braking gap equally and can not adjust defective automatically, influence vehicle braked.
The purpose of this utility model is to provide a kind of can eliminate unnecessary excessive gaps at any time automatically, not influenced by personal factor, makes the safe and reliable braking automobile of brake adjust arm automatically.
The technical solution of the utility model is to realize like this.This braking automobile is adjusted arm automatically, it includes housing, worm screw, worm gear, cover plate, worm screw is housed in the housing, the worm and wheel engagement, housing simultaneously is fixed with cover plate, it is characterized in that control unit is to connect control arm on the control panel, the mutual rigid joint of control arm and control panel, and can freely rotate as an integral body along lid surface, one breach that matches with the spur rack elbow is arranged on the control panel, between spur rack and housing Returnning spring is housed, and control unit is fixed in the housing with screw, overrunning clutch middle gear engagement on spur rack and worm screw one end, the worm screw the other end is the elasticity perceptron, engagement can drive the worm gear that S type cam shaft rotates in the middle of the worm screw.
Above-mentioned overrunning clutch is that gear, clutch spring, clutch ring cooperate successively and assemble, and worm screw one end is with gear earlier, and there is annular groove on the surface in the gear, and interior dress clutch spring overlaps the clutch ring then again on the worm screw.
Above-mentioned elasticity perceptron is that worm screw one end helical spring and worm screw the other end conical clutch constitute.
After the utility model entrucking, only need join the control panel locating stud in addition can finish installation, and as long as its shell of transposing can be installed convenience, economy, highly versatile on different automobile types.After automobile runs certain stroke, after interior friction disc wear or excess gap produce,, just can make brake reply normal clearance as long as adopt brake for several times, guaranteeing safety traffic, thereby abandon over the personal factor of artificial manual adjustment, the hidden danger that elimination is hidden.Especially adopt straight wide type worm screw of normal direction and fine module gear to make the work of adjustment arm more reliable and more stable.
Description of drawings:
Fig. 1. the utility model braking automobile is adjusted arm configuration office automatically and is cutd open figure;
Fig. 2. for D-D among Fig. 1 to sectional view;
Fig. 3. for E-E among Fig. 2 to sectional view;
Fig. 4. for braking automobile is adjusted arm configuration schematic perspective view (housing, cover plate are depicted as vitreousness virtually) automatically.
Below in conjunction with description of drawings embodiment of the present utility model is further described:
As shown in the figure, its housing 1 is made for spheroidal graphite cast iron, and through the salt bath processing, its friction factor is low and wear-resisting property good, lining 2 is made by Chilled Hardened Steel, design corresponding size according to customer requirement, control unit is finished and is adjusted required the moving of arm compensating movement, it is by control panel 16, control arm 17 and cover plate 18 are formed, control arm and control panel be rigid joint each other, and can freely rotate as an integral body along lid surface, between cover plate and the control arm seal ring is arranged, see Fig. 4, in order to show that the inside part connects, we are with housing, cover plate is depicted as vitreousness virtually, make things convenient for intuitivism apprehension, have on the control panel between a breach 19 that matches with spur rack 3 elbows and tooth bar and the housing Returnning spring 5 is housed, stopper 15 is blocked the mount inlet of returning spring in the housing, see Fig. 1, sealing gasket is installed between control unit and the housing, and control unit is fixed in the housing with screw, overrunning clutch middle gear 8 engagements on spur rack and worm screw 20 1 ends, see Fig. 4, overrunning clutch is converted to axial motion with the tooth bar linear motion, it is by gear 8, clutch spring 7, clutch ring 6 cooperates successively and assembles, see Fig. 2, worm screw one end is with gear 8 earlier, and dress clutch spring 7 in 8 li surperficial open loop grooves of gear overlaps clutch ring 6 again on the worm screw then and constitutes, the flexible perceptron of the worm screw the other end, see Fig. 2, it should go up helical spring 10 and the other end conical clutch formation by end for worm screw, and conical clutch is made up of worm screw end and clutch ring 6, all there is tooth the taper position of worm screw and the inboard of clutch ring, the two engagement the time is called the conical clutch combination, otherwise when throwing off, is called conical clutch and separates.Driving S type cam shaft again with the worm gear 4 of worm meshing rotates and adjusts braking gap.Needle bearing 12 is fixed in worm screw one end on the housing by rivet 14 and screw lid, and needle bearing and worm screw one end liner have O RunddichtringO 13, and the worm screw the other end is fixed on the housing by thrust washer 9, helical spring 10 and screw lid 11.Its tooth of worm screw is the straight wide type of normal direction, and worm and wheel is made by the high tensile steel through special processing, and gear 8 moduluses are in 0.220 millimeter, and the number of teeth improves degree of regulation and working stability more than 80 like this.
During its normal braking, control panel rotates relative to adjusting arm, be that breach promotes spur rack and rotates overrunning clutch on the control panel, this moment, the overrunning clutch separation was slipping state, be that gear rotates relative to the clutch spring, simultaneously S type cam shaft promote brake shoe until wearing piece with till brake drum contact, also compression helical spring is axially moved in the stressed back of worm screw, clutch separates with the worm screw conical tooth at this moment.When the excess gap, control panel moves on continuing relatively, rise rapidly until S type cam shaft torsion, promote whole free-wheeling assembly, when the brake of excess gap discharges, S type cam shaft torsion descends, and makes helical spring promote worm screw and moves to left, and this moment, worm screw conical surface tooth and overrunning clutch clutch loops closed, control panel is adjusted arm relatively and is moved down, this moment, two clutch drove the worm screw rotation by spur rack, and worm screw drives the worm gear rotation, the while worm gear drives S type cam shaft again and rotates to an angle, thereby finish once adjusting play action automatically, this mechanism can experience gap length automatically and implement automatic the adjustment, to keep brake and the normal fixed interval (FI) of brake drum.
