Description
One, technical field
The utility model relates to a kind of disk type braker, particularly relates to the disk type braker that a kind of automobile back wheel is used.
Two, background technique
The particularly medium-to-high grade car of existing automobile, its front wheel brake adopts disk type braker, and trailing wheel is braked then employing dish drum brake, is finished by the drum brake of braked-disc hub portion during parking braking.And disk type braker (fixation clamps type) is all adopted in another kind of automobile front and rear wheel braking, but needs to install the auxiliary braking pincers that a cover is used for parking braking additional at trailing wheel.These two kinds of brake structurals are all complicated, and installation difficulty is higher, therefore exist the chance of braking failure more, drawback such as manufacture cost height.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of possess service brake and two kinds of functions of parking braking and automobile back wheel disk type braker simple in structure are provided.
The purpose of this utility model realizes by following technical solution: a kind of automobile back wheel disk type braker, comprise caliper, shoe plate, support, oil inlet hole, bleed screw, piston, rectangular loop, wherein the front end of the rectangle ring recess in the caliper cylinder hole has chamfering structure, the steel ball sleeve screw rod is housed in caliper and stretches out the caliper end and link to each other, use nut check with swinging mounting, caliper is equipped with fixed support on the end, and swinging mounting links to each other with torsion spring with fixed support; On the steel ball sleeve screw rod steel ball sleeve is housed, has the corresponding circular arc surface groove in both sides between steel ball sleeve screw rod and the steel ball sleeve, on described circular arc surface groove, be provided with steel ball; The steel ball sleeve screw rod links to each other with threaded guide rod by the anti-attrition pad, is provided with pressure spring and spring socket sleeve below the threaded guide rod, and threaded guide rod is peripherally equipped with the adjustment swivel nut, and threaded guide rod and the connecting thread of adjusting between the swivel nut are the four-head buttress thread form; Adjust swivel nut and link to each other with piston again, adjusting between swivel nut and the piston, be connected with toothed washer, wave washer, plain washer, plane bearing successively and form as one with the adjustment swivel nut by the check ring on the piston inner hole.
After adopting the utility model structure, realize parking braking by the mechanical transmission that in the caliper cylinder of former disk type braker, installs a cover promotion cylinder inner carrier additional, and this mechanical transmission can be adjusted the requirement that satisfy service brake automatically along with the service brake state when needing service brake, and is constant to guarantee the prepsetting gap between shoe plate and the brake disc.Therefore, the utility model can have service brake and two kinds of functions of parking braking simultaneously, and simple in structure, low cost of manufacture, easy for installation, good braking effect.
Four, description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model automobile back wheel disk type braker and installation thereof.
Fig. 2 is the partial enlarged drawing of the mark I among Fig. 1.
Fig. 3 is the partial enlarged drawing of the mark II among Fig. 1.
Fig. 4 is the partial enlarged drawing of the mark III among Fig. 1.
Five, embodiment
Referring to figs. 1 through Fig. 4 as can be known, the utility model automobile back wheel disk type braker, comprise caliper 1, shoe plate 2, support 3, oil inlet hole 4, bleed screw 5, piston 6, rectangular loop 7, wherein the front end of the rectangle ring recess in the caliper cylinder hole has chamfering structure (as shown in Figure 2), steel ball sleeve screw rod 8 is housed in caliper 1 and stretches out the caliper end and link to each other with swinging mounting 9, lock with nut 10, fixed support 11 is housed on the caliper end, and swinging mounting 9 links to each other with torsion spring 12 with fixed support 11; Steel ball sleeve 13 is housed on the steel ball sleeve screw rod 8, has the corresponding circular arc surface groove (as shown in Figure 3) in both sides between steel ball sleeve screw rod 8 and the steel ball sleeve 13, on described circular arc surface groove, be provided with steel ball 14; Steel ball sleeve screw rod 8 links to each other with threaded guide rod 16 by anti-attrition pad 15, be provided with pressure spring 17 and spring socket sleeve 18 below the threaded guide rod 16, threaded guide rod 16 is peripherally equipped with adjusts swivel nut 19, threaded guide rod 16 and to adjust connecting thread between the swivel nut 19 be four-head buttress thread form (as shown in Figure 4, its role is to make swinging mounting to rotate less angle and adjust swivel nut obtain bigger displacement); Adjusting swivel nut 19 links to each other with piston 6 again, adjusting between swivel nut 19 and the piston 6 by the check ring on the piston inner hole 20, be associated with successively toothed washer 21, wave washer 22, plain washer 23, plane bearing 24 and with adjust swivel nut 19 form as one (as shown in Figure 4, effect is to make it cannot produce motion respectively).3 steel balls wherein evenly distribute on the circular arc surface groove; The effect of anti-attrition pad is to reduce the frictional force between steel ball sleeve screw rod and the threaded guide rod; Above-mentioned four-head buttress thread form has the characteristics of single load bearing, helps resetting when the brake off so that produce when adjusting swivel nut and being subjected to thrust to move axially with threaded guide rod; The wearing and tearing of shoe plate, brake disc when eliminating gap or service brake need to adjust swivel nut and constantly compensate automatically with piston, make the gap between shoe plate and the brake disc be made as definite value.
When the needs service brake, hydraulic oil flows in the caliper cylinder from oil inlet hole, piston moves forward under the effect of oil pressure F1, drive the chamfering place distortion of rectangular loop in caliper cylinder hole, pistons end promotes shoe plate and presses to brake disc 26 (its pressure is F2), produces reaction force F3 in bottom, caliper cylinder hole simultaneously, caliper is moved backward, thereby drive another shoe plate and press to brake disc, under the effect of F2 and F3, brake disc is stopped operating, reach the service brake purpose.Drive the adjustment swivel nut when piston forward moves and move forward, and be subjected to the tensile force f 7 of threaded guide rod and the reaction force F8 that the compressed waveform packing ring produces, make the rotation of adjustment swivel nut and the displacement synchronous of piston.
After service brake was removed, the tensile force f 7 of threaded guide rod and the reaction force F8 of wave washer equalled zero, and adjusted swivel nut return under the effect of piston returning place force, made the prepsetting gap between shoe plate and the brake disc constant.
When the needs parking braking, automobile stops the back rotating swinging mounting with pulling moving wire rope 25, driving the steel ball sleeve screw rod simultaneously rotates, this moment, steel ball rolled in the circular arc surface groove, and then the promotion threaded guide rod moves forward generation thrust F4 (pressure spring has spring force F5 simultaneously), under the effect of F4, make to adjust the swivel nut rotation and drive piston forward and move (meanwhile, rectangular loop is to caliper cylinder Hole chamfering place distortion) promote shoe plate and press to brake disc, moving another shoe plate of shipper pole is pressed to brake disc behind the effect lower clamp of reaction force, thereby reaches the parking braking purpose.
After removing parking braking, swinging mounting makes steel ball get back to original position so that the steel ball sleeve screw rod automatically resets along the circular arc surface groove under the effect of the spring force F5 of torsion spring torsion F6 and pressure spring.Threaded guide rod pulling is simultaneously adjusted swivel nut and is retreated, and makes the piston return under the effect of rectangular loop, makes the prepsetting gap between shoe plate and the brake disc constant.
