A set of the parking mechanism and the top rod pushing mechanism is additionally installed in the brake caliper body of the brake caliper assembly, and the brake caliper assembly further has the three functions of service braking, parking braking and emergency braking, so that the volume of the brake is reduced to adapt to the limited space of the automobile chassis, and the brake has a simple structure, is convenient to install and ensures the stability of braking effect, and meanwhile, the braking effects during the traveling and reversing of the automobile are consistent.
Description
One, technical field
The utility model relates to the pure disc type machinery of a kind of automobile Parking Brake, belongs to the brake system of car field.
Two, background technique
At present, automobile brake employing dish drum-type machinery Parking Brake, it can realize service brake (disc type), parking braking (drum-type) and emergency brake, but brake caliper assy (service brake with), halting mechanism (parking braking with) are respectively two different mechanisms.When the needs service brake, import oil pressure by giving in the braking clamp body, the oil pressure effect makes the brake pad that is distributed in the brake disc both sides that brake disc is embraced, and makes traveling automobile slow down or stop to travel; After automobile stopped to travel, operating grip drives halting mechanism by backguy opened two brake shoes that are distributed in circle in the brake disc, props up circle in the brake disc, makes automobile remain on the original place.
This brake structural more complicated, shared space is big; Halting mechanism for neck from shoe type drum-type structure, the advance braking effect in (the place ahead) of automobile is higher than the braking effect at rolling-back of car (rear); After circle wearing and tearing in brake shoe and the brake disc, need artificial adjusting play, therebetween since the de-stabilising effect of brake clearance the stability of braking effect.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of and service brake and parking braking, three kinds of functions of emergency brake can be focused in the same mechanism, pure disc type machinery Parking Brake simple in structure.
The purpose of this utility model realizes by following technical solution: a kind of pure disc type machinery Parking Brake, comprise brake caliper assy, brake disc, hub-bearing unit, swinging mounting and backguy, in the braking clamp body of described brake caliper assy halting mechanism is housed, the threaded guide rod of halting mechanism and push rod pushing mechanism link; Described swinging mounting and push rod pushing mechanism link.Described push rod pushing mechanism is linked by eccentric shaft and push rod and constitutes, and the threaded guide rod of push rod and halting mechanism links, and eccentric shaft and swinging mounting link.
After adopting the utility model structure, by in the braking clamp body of brake caliper assy, installing a cover halting mechanism and a push rod pushing mechanism additional, make brake caliper assy possess service brake and parking braking, three kinds of functions of emergency brake simultaneously, thereby reduced the volume of break, adapting to the limited space of automobile chassis, and simple in structure, easy for installation.And can realize the automatic adjustment in service brake, parking braking gap, and guaranteed the stability of braking effect, simultaneously automobile advances consistent with the braking effect that retreats of moveing backward.

Fig. 2 is the plan view of the brake caliper assy among Fig. 1.
Fig. 3 is the plan view of Fig. 2.
Five, embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and mode of execution.
Referring to figs. 1 through Fig. 3 as can be known, the pure disc type machinery of the utility model Parking Brake, comprise brake caliper assy 1, brake disc 4, hub-bearing unit 3, mudguard wing assembly 2, swinging mounting 3b and backguy 6b (backguy is located on the swinging mounting), in the braking clamp body 1a of described brake caliper assy 1 halting mechanism 4a is housed, the threaded guide rod 2b of halting mechanism 4a and push rod pushing mechanism 7b link; Described swinging mounting 3b and push rod pushing mechanism 7b link.Described push rod pushing mechanism 7b is linked by eccentric shaft 5b and push rod 1b and constitutes, and the threaded guide rod 2b of push rod 1b and halting mechanism 4a links, and eccentric shaft 5b and swinging mounting 3b link.Use the advantage of eccentric shaft 5b to be that its manufacturing is simple, mechanical loss is less.
With reference to Fig. 2, Fig. 3 as can be known, brake caliper assy 1 comprises braking clamp body 1a, mounting bracket 2a, brake pad 3a, halting mechanism 4a, and described halting mechanism 4a is contained in the braking clamp body 1a, and push rod pushing mechanism 7b also is housed in the braking clamp body 1a; Halting mechanism 4a comprises piston 4b, threaded guide rod 2b etc. (for known technology), and its piston 4b and brake pad 3a join, and can drive brake pad (being made of inside and outside brake pad).Wherein said braking clamp body 1a adopts casting aluminium material, its light weight, exquisite appearance is small and exquisite, intensity is high, and described disc material is that HT250, mudguard wing assembly material are that 08Al, braking clamp body material are that cast aluminium alloy ZL111, mounting bracket material are QT500-7.Rotatable member in the disk type braker friction pair is the discoid brake disc that is installed on the wheel, and its working surface is both ends of the surface.Fixed element is the brake caliper assy of the band brake pad of bulk.Braking clamp body is its two strands and strides the clamp-shaped parts that clip brake disc that its inside processes columnar oil cylinder, and piston wherein is housed.The internal brake pad of piston forward is exerted pressure during braking, and brake pad slides and is resisted against on brake disc one surface along the brake pad groove in making; At this moment because the external pressure and the surface friction drag of interior brake pad and brake disc make braking clamp body along the slippage backward of its sliding axle, pulling external friction piece is against another surface of brake disc, at this moment, the tangential force of two brake pads forms a counter-force and produces braking moment the sense of rotation of brake disc.
The utility model is the break that integrates service brake, parking braking, three kinds of functions of emergency brake.Service brake is to import oil pressure by giving in the braking clamp body, and the oil pressure effect makes the brake pad that is distributed in the brake disc both sides that brake disc is embraced, and makes traveling automobile slow down or stop to travel.It is when piston moves past this segment distance of spatial joint clearance that Service Brake unclamps, and makes the rectangular seal distortion that remains static, and the seal ring that has become shape when release brake retracts piston this segment distance of air clearance to the direction that reduces brake fluid pressure.Parking braking is after vehicle stops to travel, operating grip drives the eccentric shaft rotation by backguy with swinging mounting 3b rotation (swinging mounting 3b and eccentric shaft 5b weld together), thereby promotion push rod 1b, threaded guide rod 2b, piston 4b motion are passed to the brake pad that is distributed in the brake disc both sides with power brake disc are embraced, and make automobile remain on the original place.Emergency brake is to have in service brake under the situation of place inefficacy, operating grip drives the eccentric shaft rotation by backguy with swinging mounting 3b rotation, thereby promotion push rod 1b, threaded guide rod 2b, piston 4b motion are passed to the brake pad that is distributed in the brake disc both sides with power brake disc are embraced, and vehicle is stopped in a suitable segment distance.
