Wherein, determine shell and shell are respectively arranged with further into and out of hydraulic fluid port.
Wherein, end face service brake piston and parking automatic piston contacted with static friction sheet is provided with groove further.
Wherein, seal ring is provided with further between shell and parking braking piston.
Implement the utility model embodiment, there is following beneficial effect: three shells one of the present utility model cover shape row wet brake in one by determining shell, shell, the large Component composition of dynamic shell three together, innovate structure, achieve good rigidly, intensity is high, easy processing, easy accessibility, reduce break manufacture and working service cost, the target be user-friendly to.This break employing full-closed structure, stable and reliable for performance, braking torque is large, and manipulation is simple, works without electrostatic, no-spark, nothing discharge, temperature-controllable.Can be widely used in general-utility car, wheeled engineering truck, farm machinery and vehicle, special adaptation, requires heavy goods vehicles or the big machinery fields such as the engineering vehicle high, service condition is harsh at explosion-proof, fire prevention, environmental pollution.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the drawing in side sectional elevation that three shells one that the utility model provides cover shape row wet brake in one.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, Fig. 1 is the structural representation that three shells one that the utility model provides cover shape row wet brake in one.Three shells one cover shape row wet brake in one and comprise: shell 10, determine shell 20, dynamic shell 30, movable friction plate 40, static friction sheet 50 and end cap 60.
Shell 10 shell is single-side flange cartridge type, and inside is provided with internal tooth and step hole, and step hole is provided with parking braking piston 11, and parking braking piston 11 is provided with groove, is provided with seal ring 13 between shell 10 and parking braking piston 11.Shell 10 end face of flange is provided with 20 diameter 12mm holes, is used for Returnning spring 12 is installed.Housing flange end face is provided with 16 bolt connecting holes, is used for and determines shell 20 bolt and be connected.Shell 10 is also provided with oil outlet.
Determine shell 20 for flange type, removably connected by bolt with shell 10.Determine shell 20 inside and be provided with groove, be detachably provided with service brake piston 21 in groove, service brake piston 21 is also provided with groove.Determine shell 20 is also provided with filler opening.
Dynamic shell 30 is long cylindrical structure, is removably connected by bolt with shell 10.Dynamic shell 30 right-hand member is set to flange type, and left end is provided with external tooth, and inside is provided with duplex bearing mounting hole site.
Movable friction plate 40 is connected with a joggle with the external tooth of dynamic shell 30 left end.
Static friction sheet 50 is connected with a joggle with the internal tooth of shell 10 inside, and movable friction plate 40 and static friction sheet 50 are alternately disposed between service brake piston 21 and parking braking piston 11.
End cap 60, for there being the plane face flange type of shoulder hole, is removably connected by bolt with shell 10, for pressing and the spring 12 on parking braking piston 11, ensures enough parking moments of torsion.
After general assembly completes, determine shell 20 and be in stationary state with shell 10, the external tooth on the internal tooth of the movable friction plate 40 in shape chamber and dynamic shell 30 is connected with a joggle, and the tooth in the external tooth of static friction sheet 50 and shell 10 endoporus is connected with a joggle.Parking braking piston 11 pressing movable friction plate 40 and static friction sheet 50 under spring force during normality, break is in parked state.When vehicle launch motor, operation of oil pump, after unclamping parking brake handle grip, hydraulic oil enters from the hydraulic fluid port at shell 10 top and promotes parking piston 11 and move to right, compression reseting spring 12, make movable friction plate 40 and static friction sheet 50 be in relaxed state, break is in driving states.When needing braking in driving a vehicle, step on foot brake pedal, hydraulic oil flows into by determine filler opening on shell 10, and promote service brake piston 21 and to move to right pressing movable friction plate 40 and static friction sheet 50, break is in service brake state.Unclamp foot brake pedal, hydraulic oil refluxes, and Returnning spring 12 promotes service brake piston 21 and moves to left, and movable friction plate 40 and static friction sheet 50 are in free state, and break recovers driving states.When vehicle stops needing parking braking, tension parking brake handle grip, hydraulic oil refluxes, and Returnning spring 12 promotes parking braking piston 11 and to move to left pressure and movable friction plate 40 and static friction sheet 50, and break is in parked state again.
Implement the utility model embodiment, there is following beneficial effect: three shells one of the present utility model cover shape row.
