Abstract
The utility model relates to a brake cylinder, which is particularly suitable for being installed in a locomotive vehicle brake system. The brake cylinder comprises piston bars which are installed in a closed cylinder hole which is at the front and rear end caps, a leather cup which is fixed at the rear end surface of the piston bar by a clip, inlet and outlet air holes which are opened on the rear end cap, a seal ring which can seal up the slumping cylinder of the piston bar and is embedded in the front end cap, and a piston bar end cap with an ear-ring which is fixed at the front end surface of the piston bar. The brake cylinder is characterized in that an extension spring which is on a front pull seat and is coaxially installed in the hollow piston bar hole, and one end of the extension spring is fixed on the ear seat of the rear cap, and the other end is fixed in the end cap of the piston bar. A trunnion is arranged on the outer wall of the cylinder. The effective travel of the piston bar can be enlarged under the condition that the axial dimension of the cylinder isn't increased.
Description
The utility model relates to a kind of brake cylinder, is specially adapted to the brake system of rail vehicles.
In existing railway rolling stock brake system, what adopt mostly is compression spring energy storage braking cylinder, be compression spring be installed in the cylinder hole and Gou Gou bar cylindrical between annular chamber in, be exactly this brake cylinder as what use in the homemade dong feng 4 diesel locomotive brake system.Its shortcoming is: in the process of locomotive brake; when the pressurized air that feeds in brake cylinder makes compression spring pressurized to spring coil gap be zero; compression spring still keeps certain length; therefore reduced the effective travel of Gou Gou in the brake cylinder; particularly when rail vehicles when long and steep downgrade snipe is travelled; the brake shoe abrasion constantly increase; the stroke of brake cylinder Gou Gou also will constantly increase thereupon; because existing brake cylinder Gou Gou stroke surplus is not enough, so regular meeting causes the braking force deficiency of rail vehicles and the traffic safety accident takes place.The cylinder body of existing brake cylinder is that fixed type is installed, glancing impact, and the moving system of braking produces deletrious diametral load and moment of flexure to Gou Gou bar.In addition, when its Gou Gou bar stretches, can not limit, be not easy to the installation of brake cylinder around himself rotational.
The brake cylinder that the utility model relates to, its purpose will overcome above-mentioned shortcoming exactly, under the condition of the axial dimension of the brake cylinder that do not extend, increase the effective travel of Gou Gou bar, in brake shoe abrasion process, can maintain enough big braking force all the time, to satisfy the requirement of rail vehicles safety arrestment when long and steep downgrade snipe is travelled.The moment of flexure of eliminating Gou Gou diametral load that bar bears and producing by it, and be convenient to install.
The brake cylinder that the utility model provides, before being included in, hollow Gou Gou bar is housed in the rear side housing osed top cylinder bore coaxially, be fixed on leather cup on the Gou Gou rod rear end ring surface with pressing plate, have on the rear side housing into, deflation hole, front end cover has been embedded in the seal ring of salable Gou Gou bar slip cylinder, Gou Gou bar front end face is fixed with the Gou Gou rod end lid of band earrings, its constructional feature is: in hollow Gou Gou bar hole extension spring is housed coaxially, the one end is fixed on pin and is hinged on the back pulling seat of bonnet ear seat, the other end is fixed on the Gou Gou bar protecgulum by pulling seat before threaded, outer wall of cylinder block is provided with the gudgeon that cylinder body is swung in fixed bearing, its axis and cylinder body axis normal.Its advantage is can be under the condition that does not increase the cylinder body axial dimension, increase the effective travel of Gou Gou bar, when satisfying the abrasion of the frequent glancing impact brake shoe of rolling stock,, guarantee the problem of traffic safety because of the caused inadequately braking force deficiency of Gou Gou throw of lever surplus in the brake cylinder.Cylinder body can be eliminated brake system around the swing of trunnion axis and at glancing impact Gou Gou bar be produced deletrious diametral load and moment of flexure thereof.With the hole of fixing back pulling seat in extension spring rear end and bonnet ear seat in the pin that forms hinge-coupled is housed, can limit Gou Gou bar and when flexible, produce rotation, be convenient to installation.
Now the brake cylinder embodiment that in conjunction with the accompanying drawings the utility model is related to describes in detail down:
The brake cylinder longitudinal sectional view that Fig. 1 the utility model relates to.
As shown in Figure 1, in fixed bearing, the cylinder body 6 that trunnion axis swing that can be on outer wall of cylinder block is arranged, have in its back-end on the bonnet that is screwed, packing seal 2 between bonnet and cylinder body binding face, be contained in the cylinder bore and the coaxial hollow Gou Gou bar 7 in cylinder hole, its rear end have by the gland 4 of an end by being threaded into Gou Gou bar, be fixed on Gou Gou bar 7 the rear end ring surface on leather cup 3, Gou Gou bar has also screwed in the fastening spiro loop 5 that can prevent that gland 4 from getting loose in the hole.Front end at hollow Gou Gou bar 7, be fixed together with Gou Gou bar and have the Gou Gou bar protecgulum 11 of earrings, in the hole of hollow Gou Gou bar 7 extension spring 12 is housed coaxially, its rear end is connected with ear seat formation hinge on the bonnet 1 by back pulling seat 13 usefulness pins 14, and the screw thread of its front end by preceding pulling seat 10 is fixed on Gou Gou rod end and covers on 11.
Glancing impact, after inlet and outlet hole A on the bonnet 1 and wind regime were connected, pressurized air entered in the cavity B of Gou Gou bar 7 rear end leather cups 3, promote the inner end surface of leather cup 3 and Gou Gou rod end lid 11, make extension spring 12 be in extended state, Gou Gou bar 7 moves to right, and stretches out in the hole of protecgulum 9.This moment, power was promoted on the wheel tread of brake shoe (not shown) with the rolling stock of braking force effect by brake system by the earrings on the Gou Gou rod end lid 11, and the maximum effective travel of braking is L.Meanwhile, brake system can be eliminated around the swing of its trunnion axis by cylinder body 6 to the diametral load of Gou Gou bar 7 generations with by the moment of flexure that its produces.
When the inlet and outlet hole A on the bonnet and atmosphere were connected, under the effect of extension spring 12, the Gou Gou bar 7 that will stretch out moved to left and is withdrawn into as shown in Figure 1 initial position.
Claims (2)
1, a kind of brake cylinder, be particularly suitable for being contained in the rolling stock brake system and use, it is included in the front and back ends lid osed top cylinder bore Gou Gou bar is housed, be fixed on leather cup on the Gou Gou rod rear end end face with pressing plate, have the inlet and outlet hole on the rear side housing, front end cover has been embedded in the seal ring of salable Gou Gou bar slip cylinder, and Gou Gou bar front end face is fixed with the Gou Gou rod end lid of band earrings, it is characterized in that:
