Abstract
The present invention relates to a brake shoe piece of a partly lined disc brake. The brake shoe piece comprises a bonding layer and a soft elastic vibration absorbing layer, wherein the bonding layer is arranged between a supporting plate and a vibration absorbing layer. Flange portions (7, 9 and 10) of a vibration absorbing piece are connected with the supporting plate to surround the lateral surface of the support plate (3). The transverse flange portion (7) of the vibration absorbing piece (4) and a dust storage chamber for restoration on the support plate (3) are matched.
Description
The present invention is about the brake shoe of partly lined disc brake device, and it comprises a support plate, and a friction plate and an absorbing sheet have bonding coat and soft elasticity shock absorption layer between support plate and absorbing sheet, and the absorbing sheet partly is connected with support plate with flanging.
As everyone knows (or connection) punching out sheet is arranged in the brake slipper box of partly lined disc brake device, be positioned on the working surface of support plate.Its effect is to make each surface of contact of above-mentioned each sheet fork the effect of soft elasitic layer to apply piston or to the connection on the Brake Block, thereby reaches the purpose of absorbing.For horizontal guiding, support and contact absorbing, on the support plate lining face or on the detent box that supports, use the plastics filler rod of simple tabs, plug-in type spring or lateral means.
When break is under the long-time big stress phase, when bonding coat is subjected to Temperature Influence inevitably, the laterally folded of simple absorbing sheet just can not guarantee that the safety between absorbing sheet and the support plate connects, though laterally twice bending of the absorbing sheet that protrudes stops support plate to unclamp when above-below direction moves, and can not prevent because mobile unclamping of causing radially with this way.Other laterally steering means or method are then very expensive as reach the contact absorbing with the plastics filler rod, nor can be clipped in the absorbing sheet on the support plate safely.
The objective of the invention is to eliminate as far as possible the vibration that the brake shoe of above-mentioned pattern transmits out, therefore adopted and adorned solid absorbing sheet safely and improve guiding and the clamping of support plate on horizontal surface of contact.Characteristics of the present invention are to have flanging partly to surround the side of support plate on the limit of absorbing sheet, and the horizontal flanging of absorbing sheet is partly connecting the recessed dust pocket of support plate.
Because the phenomenon that the absorbing sheet unclamps has been got rid of in the horizontal clamping of absorbing sheet safely on the support plate of brake shoe, makes the laterally steering of the absorbing sheet on support plate and cross-brace become reliable simultaneously.For this purpose, adopt a kind of like this support plate, its side is not continuous, but a recessed dust pocket is arranged, and this dust pocket provides safety and perfect means, and absorbing sheet and support plate are clamped together.
Another characteristics of the present invention be having up and down of absorbing sheet have corresponding additional support tongue piece flanging part in order to connect support plate.These additional support tongue pieces form horizontal surface of contact, play a part the contact absorbing between support plate and Brake Block.Support tongue piece engaging the outer side surface of support plate, so the pressure of the unit area that the contact absorbing causes is not too big, this just makes shock absorption layer avoided too early wearing and tearing.
Another characteristics of the present invention are side central position flanging parts that the dust pocket of the removing usefulness of these and support plate is connected, and are made into the curved limit that shakes twice, and this just forms the firm clamping that can not move.By the support tongue piece that a dihedral is partly formed, fully engaging the outer side surface of support plate.
The width of the corresponding folding edge of flanging part with support the width of tongue to reduce, to bending partly to be easy to manufactured be favourable.Same reason, the central position side of support plate and the back side (shown in sectional drawing) should form the angle less than 90 ° mutually.
The present invention will further describe with a represented embodiment of accompanying drawing.
Fig. 1 illustrates brake shoe of the present invention, from this face of friction plate, the horizontal clamping of the absorbing sheet that is arranged in the back side is shown.
Fig. 2 is half a transverse views of absorbing sheet, and this moment, transverse fin or tongue piece were crooked as yet.
Fig. 3 is half a transverse views (can see from working surface) of brake slipper of the present invention, comprises the absorbing sheet that is closing, and fin is partly by bending.
Fig. 4 is the sectional drawing of the amplification of giving along IV-IV among Fig. 3.
The brake shoe 1 of partly lined disc brake device comprises braking lining 2, one support plates 3 and an absorbing sheet 4, and the dust pocket 8 of the removing usefulness of absorbing sheet 4 usefulness twice flanging 7 and support plate 3 is connected.In addition, absorbing sheet 4 also comprises simple flanging 9 and 10, be positioned at the top of twice bending 7 and below.
Fig. 2 demonstrates the absorbing sheet 4 that punching out goes out, and three pairs of tongue pieces or fin are arranged on its limit.The fin 7 of central authorities is than two other tongue piece 9 and 10 long, it press bending line 7 ' with 7 " by twice bending.The tongue 9 and 10 of outside all only bends guiding, support and the contact surface that once forms the support plate on the Brake Block.The arris 7 that fin or tongue piece will bend afterwards ', 7 " and 9 ', 10 ' the position, its width is reduced by fillet.
Fig. 3 and 4 demonstrates the clamping of absorbing sheet 4 and support plate 3, and this is to finish by the dust pocket 8 that twice folded over tab 7 that the former central flanging partly forms enters the latter.At this position, the side of support plate and the back side (shown in sectional drawing) forms one less than 90 ° angle, and this makes central flanging partly 7 can surround the surface that the support plate fovea superior is cut. Tongue piece 9 and 10 quilts of outside bend once, are pasting the outer side surface of support plate 3 straightly.Bonding coat 5 and shock absorption layer 6 are represented with thick line in Fig. 4.
The final position that Fig. 4 does not draw twice bending edge 7 as yet, the surface engagement of fin and support plate during the final position.
