Friction disk is after wearing and tearing after a while, frictional force can diminish, and influences the effect of clutch, braking, and this need adjust the friction gap, this gap adjustment of existing combined clutch break also is very inconvenient, also needs to take apart by the professional workforce and just can finish.
The model utility content
The technical problems to be solved in the utility model provides a kind of combined clutch break easy to maintenance.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme: a kind of combined clutch break, comprise cylinder, piston, supporting disk, pressure strip and two friction disks, described supporting disk is fixedlyed connected with cylinder, described pressure strip is fixedlyed connected with piston, described friction disk comprises circular discs and at a plurality of friction plates of disc upper edge circumferential arrangement, described friction plate is made of pedestal and the friction material that is fixed on the pedestal, the outer rim of described pedestal is provided with fixing device, and described pedestal removably connects by fixing device and described disc.
The utility model is fixed on friction material on the pedestal, and then pedestal is fixed on the disc of friction disk, when needing to change after the friction material wearing and tearing, as long as the pedestal of friction plate is disassembled from disc, the friction plate that more renews gets final product, and do not need to change whole friction disk, so not only can save material, reduce cost, the more important thing is, because the pedestal of friction plate is to be fixed on the disc of friction disk by its exposed outer rim, more do not need the combined clutch break is removed from lathe during renewal of facing renewal, also do not need it is taken apart, just renewal of facing renewal more is very convenient.So just significantly reduce the more workload of renewal of facing renewal, maintenance man's requirement has also been reduced, do not needed the professional workforce also can finish repair and replacement.
In technique scheme, the outer rim of pedestal is provided with screw hole, pedestal by screw on disc, as long as unclamp just renewal of facing renewal more of screw.
In the above-mentioned friction plate, friction material is bonded on the pedestal by glue.
As a kind of preferred version of technique scheme, the position that pressure strip contacts with friction disk is provided with one and adjusts plate, and described adjustment plate is connected by screw with pressure strip.After friction plate has produced certain wearing and tearing, pressure strip can diminish to the pressure of friction disk, influence braking effect, this moment is as long as unclamp the attachment screw between pressure strip and the adjustment plate a bit, make pressure strip and adjust between the plate and produce certain clearance, in this gap, insert pad then, at last screw-driving is got final product.Compensate by the wear extent of this structure friction plate, can solve easily because wearing and tearing cause the hypodynamic problem of braking, and this operation does not need dismounting yet, does not need the professional workforce, and is very convenient to the running repairs of combined clutch break.
