The first O-shaped ring and the second O-shaped ring are arranged in a groove formed in the end face flange, the end face flange is connected with the connection shaft through a second set of screws, and the pneumatic disc brake body is fixed on the connection shaft.
Description
Technical field
The utility model relates to a kind of air disc brake, relates in particular to the structure of this air disc brake.
Background technique
Air disc brake is applied to various machinery, realizes that clutch moment is transmitted rapidly and the fast braking of equipment driven member.
The air disc brake of prior art all adopts axle upper air form, namely in one of the center processing that is connected axle head with disk type braker axial admission hole, radially process an air outlet hole vertical with the axial admission hole at axle, air outlet hole is aimed at the inlet hole of disk type braker endoporus, and the external compression air can enter the disk type braker cylinder smoothly.For preventing compressed air leakage, at disk type braker both sides end face, a sealed cover is installed respectively, an endoporus O type circle and end face O type circle are installed on sealed cover.Be processed with screw thread and configuration lock jack panel at connection axle head external diameter, locking nut is fixed on disk type braker and both sides sealing cover plate on coupling shaft, thereby realizes the fixing and compressed air sealing of disk type braker and coupling shaft.The drawback of axle upper air is: one, endoporus O type circle easily damages, and during due to the installation sealed cover, endoporus O type circle must be through the radially air outlet hole on axle, and the air outlet hole sharp edge is very easily cut bad O type circle; Two, fabricating cost is high, and connecting the axle head external diameter must machining screw and the axial admission hole, and must the configuration lock jack panel; Three, maintenance is complicated, when the damage of the O type circle on the inner seal cover plate causes gas leakage, disk type braker must be pulled down could change; Four, installation cost is high, because the component that must install are many, must increase the time of assembling and produce higher assembly cost.
Summary of the invention
The utility model technical issues that need to address have been to provide a kind of air disc brake of end face air inlet, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: the air disc brake body; Described air disc brake body comprises: cylinder body, piston, clutch base, Compress Spring, drag friction group, clutch friction group, the first seal ring and the second seal ring; Described cylinder body is processed with inlet hole, cylinder body and clutch base are by first group of screw attachment, described piston is installed in cylinder body and can be moved axially by relative clutch base, and the first seal ring and the second seal ring are installed between cylinder body and piston, is used for the pressurized air in sealed cylinder block; At piston and clutch base intermediate arrangement, one group of Compress Spring is arranged, the drag friction group is arranged between cylinder body and piston, and the clutch friction group is arranged between piston and clutch base, and Compress Spring is used for piston reset closes clutch friction group disengagement drag friction winding; Also comprise: air inlet end face and coupling shaft; Described inlet end face comprises: end face flange, an O type circle and the 2nd O type circle; A described O type circle and the 2nd O type circle are arranged in the groove of end face flange; The end face flange connects with coupling shaft by second group of screw, and the air disc brake body is fixed on coupling shaft.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting the end face intake type, pressurized air directly enters cylinder by the B hole on air inlet end cap and cylinder body, need not processing gas inlet hole, air outlet hole and external thread of shaft end on coupling shaft, has greatly reduced the fabricating cost of coupling shaft; The rate of fault of gas leakage when reduce installing, thereby keep in repair more conveniently, even the improper damage of the O type circle that inlet end covers assembling causes gas leakage, only need simply the air inlet end cap is pulled down and change O type circle, need not the dismounting disk type braker; Improve the disk type braker installation efficiency, saved the disk type braker installation time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As seen from Figure 1, the utility model comprises: the air disc brake body; Described air disc brake body comprises: cylinder body 4, piston 5, clutch base 9, Compress Spring 8, drag friction group 6, clutch friction group 7, the first seal ring 13 and the second seal ring 14; Described cylinder body 4 is processed with inlet hole B, cylinder body 4 and clutch base 9 connect by first group of screw 12, described piston 5 is installed in cylinder body 4 and can be moved axially by relative clutch base 9, the first seal ring 13 and the second seal ring 14 are installed between cylinder body 4 and piston 5, are used for the pressurized air in sealed cylinder block 4; At piston 5 and clutch base 9 intermediate arrangement, one group of Compress Spring 8 is arranged, drag friction group 6 is arranged between cylinder body 4 and piston 5, clutch friction group 7 is arranged between piston 5 and clutch base 9, and Compress Spring 8 resets for piston 5 and makes clutch friction group 7 throw off drag friction groups 6 joints; Also comprise: air inlet end face and coupling shaft 10; Described inlet end face comprises: end face flange 1, an O type circle 2 and the 2nd O type circle 3; A described O type circle 2 and the 2nd O type circle 3 are arranged in the groove of end face flange 1; End face flange 1 connects with coupling shaft 10 by second group of screw 11, and the air disc brake body is fixed on coupling shaft 10.
Working principle of the present utility model is: the pressurized air from the outside enters cylinder by the inlet hole B that compressed air inlet A enters on end face flange 1 air vent channel and cylinder body 4, pushing piston 5 actions, piston 5 overcomes Compress Spring 8 power and moves right, on the compacted clutch base 9 of clutch friction group 7, realize that clutch engages.When cylinder body 4 compressed airs were discharged by the A mouth on end face flange 1, due to the effect of Compress Spring 8, piston 5 was moved to the left and resets, and drag friction group 6 is pressed on cylinder body 4, realizes brake engagement.
