Description
Technical field
The utility model relates to a kind of syndeton for single-track vehicle brake disc, belongs to the brake disc technology neck of single-track vehicleTerritory.
Background technology
The out of shape of single-track vehicle taken turns as rubber wheel, and its axletree is hole-bored axle from end to end, and two layouts of taking turns out of shape are comparatively concentrated. Therefore,Due to the restriction of single-track vehicle structure and bulk, cannot axletree and wheel on arrange brake rigging, its brake disc clothPut on gear-box jackshaft. Car brakeing process, clamp action drives brake pad to act on and is installed on gear-box jackshaftBrake disc, and act on gear-box, thereby realize car brakeing.
And urban rail transit vehicles can be divided into shaft-mounted and take turns two kinds of dress formulas according to its mounting structure with brake disc at present, it is rightShould be arranged on respectively on axletree and on wheel on ground.
Wherein, domestic and international conventional shaft mounted type brake disc structure is general main by monoblock type or split type disk body, hub, spacer ringAnd the compositions such as connector such as bolt, nut. Disk body inner edge position is designed with and connects pawl structure, is provided with bolt connecting hole on it;Hub adopts and connects pawl or flange arrangement, and is connecting design bolt connecting hole corresponding to disk body on pawl and flange; When assembling, dishBody is positioned at hub one side, and by connectors such as spacer ring and bolt, nuts, disk body is fixed on hub; And assembling after brake disc,Further be fitted on axletree by hub bore interference fit, thereby realize the installation of brake disc and axletree.
The shaft mounted type brake disc of this type, it is more that it realizes the connector that hub is connected with disk body, and to hub and disk body connecting portionPosition and the dimension precision requirement of the syndetons such as the hole of position are higher, the location of syndeton and dress on assembling process disk body and hubJoin required precision also higher.
, for monoblock type brake disc, when it is changed in maintenance, complete after the connection disassembling of disk body and hub meanwhile, be positioned at axletreeOn disk body must cut and can dismantle, meanwhile, need the split type disk body of design, just replaceable new disk body, otherwise need move back wheel alsoReinstall, and split type body structure reliability is poorer compared with unitary tray body, therefore the type shaft mounted type brake disc manufacture andLater stage repair and maintenance cost is higher.
For low floor vehicle, also there is the wheel of new structure brake disk mounted, disclosed " a kind of light rail of ZL201220020049.XWheel for vehicle edge brake disc ", its two drag rings are all positioned at wheel web one side, and by the installing hole on mounting flangeBe connected with wheel, process and change more for convenience, but the hollow shaft path portion of its design, the structure of bearing at braking procedure shouldPower is larger; Connecting flange structure adopts screw to be connected to wheel, nothing installation and positioning structure accurately, and braking torque is all logicalCross screw transmission, the braking torque that braking procedure attachment screw bears is larger.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, and positioning precision is high, connection is braked for single-track vehicle reliablyThe syndeton of dish.
The utility model is that the technical scheme achieving the above object is: a kind of syndeton for single-track vehicle brake disc, bagDraw together the disk body of the interior drag ring of having of one and external friction ring, and between interior drag ring and external friction ring, there are a plurality of columnsRadiating ribs, is characterized in that: described disk body has the inner edge mounting flange of one, and inner edge mounting flange is provided with at least twoIndividual installing hole and at least two dowel holes, the mounting flange with axis hole is provided with corresponding at least two screwed holes and extremelyFew two step dowel holes, and heavy stand on step dowel hole is towards installed surface, and the installed surface of mounting flange is fitted inOn the installation locating surface of inner edge mounting flange inner side, each alignment pin be arranged on step dowel hole that mounting flange is corresponding and inIn dowel hole corresponding to edge mounting flange, the heavy stand of the bulge loop on described alignment pin and step dowel hole matches, each screwPass installing hole corresponding on inner edge mounting flange and be screwed in the screwed hole that mounting flange is corresponding.
Single-track vehicle of the present utility model has adopted the body structure of mounting flange and one with brake disc, rub on disk bodyWipe between ring and external friction ring and connect into overall structure by radiating ribs, make disk body there is the inner edge mounting flange of one, make dishBody structure is simple, compact, and can keep good radiating effect, has reduced processing and assembling procedure, has reduced processing and groupDress difficulty, has saved production and replacement cost. The inner edge mounting flange of the utility model disk body is by screw and alignment pin and companyActing flange dish connects, and mounting flange is arranged on a side of disk body, has saved the structural member such as hub and spacer ring, overall structure letterSingle, solve the problem that brake disc that two drag rings are arranged in structure on two sides need to cut inner side drag ring in the time changing, and nothingMust design split type brake disc, maintenance is changed convenient, has saved repair and maintenance cost. The utility model is at inner edge mounting flangeBe provided with at least two installing holes and at least two dowel holes, and mounting flange is provided with corresponding screwed hole and at least twoStep dowel hole, ensures that by the alignment pin with bulge loop mounting flange has higher positioning precision while installation. SimultaneouslyAlso can effectively avoid screw in the time of Joint failure, directly to bear braking torque, connect reliably, improve structural reliability and safetyProperty.
