Description
Technical field
The utility model relates to a kind of brake disc/wheel hub connection and a kind of brake disc that is used to connect brake disc and wheel hub.
Background technique
For thereby the braking moment that brake disc is connected on the wheel hub and produce in order will to brake the time is delivered on the wheel hub and is delivered on the wheel of connection, the shape lock uint of the profile of tooth of known mutual interlocking, this shape lock uint comprise a plurality of supporting elements on the interior week that is arranged on brake disc, the formation ring gear and are preventing to rotate a plurality of moving parts of taking on the periphery corresponding, that be arranged on wheel hub, that form external toothing on the meaning with it.
For brake disc is axially fixed on the wheel hub, use the connection set of rigidity so far, by this connection set fixing brake disc on the meaning that clamps.But because manufacturing tolerances is not guaranteed the firm fixing of brake disc, thereby in servicely cause screaking of brake disc travelling, in described tolerance range because brake disc can move axially.
The thermal load that produces when braking also often is debatable, and also causes its axial expansion in join domain except the radial expansion of brake disc.
The frictional heat that produces during braking to the member that participates in, particularly to the influence of the brake disc that tends to form crackle thus in this problem of the primordial in service of brake disc.
The model utility content
The purpose of this utility model is, further develops a kind of brake disc/wheel hub connection and a kind of brake disc, makes to improve the working life of brake disc and the installation and removal of simplifying brake disc with the expense on the structural and manufacturing technology seldom.
Described purpose realizes by a kind of brake disc/wheel hub connection that is used to connect brake disc and wheel hub, the brake disc that wherein has friction ring in both sides has the ring gear that is formed by a plurality of supporting elements on the interior week at it, this ring gear embeds being taken in the external toothing that moving part forms in case spline is moving by a plurality of of wheel hub, and brake disc passes through the flange portion axial restraint of at least one spring element and/or bail wire and/or wheel hub.Perhaps, described purpose realizes that by a kind of brake disc this brake disc has the friction ring of both sides and have the ring gear that is formed by a plurality of supporting elements on week in this brake disc, and wherein brake disc is 180N/mm by minimum tensile strength
2Gray cast iron constitute and this brake disc is the mirror image symmetry, make it possible to the installation of independent of direction ground.
According to a kind of advantageous embodiment, described at least one spring element and/or bail wire are arranged on the side relative with flange portion of brake disc.
Particularly by spring element with brake disc with defeating on the flange portion that comes to wheel hub of determining, realize axial fixing thus on the one hand, as the axial expansion that is caused by heat load, same compensation is about the tolerance of the thickness of brake disc in regional with reclining of wheel hub on the other hand.
In order to connect brake disc and wheel hub, can be provided for torque and power the intermediary element on the supporting element that moving part is delivered to brake disc taken from wheel hub, wherein these intermediary element are embedded into respectively in taking the gap that forms between moving part and the supporting element, thereby guarantee torque is delivered on the wheel hub from brake disc on two sense of rotation.
These intermediary element make can dismantle brake disc, for example in order to change it, releases each intermediary element for this reason, thereby can take off brake disc.
Form with the crackle that helps reducing in brake disc that separates of the material of wheel hub by the brake disc that uses intermediary element to obtain.
Each intermediary element can constitute U-shaped or basically strip-type, I shape, L shaped or T shape, and by the flange portion of bail wire and/or wheel hub and/or by each spring element axial restraint.
The intermediary element that strip-type constitutes for example is made for stamping part by sheet material because their simple geometric can be made especially simply.Particularly by the bail wire axial restraint in the groove that embeds wheel hub the time, obtain having no the installation of difficulty, wherein bail wire is guaranteed each intermediary element and the brake disc axial restraint on wheel hub.
Intermediary element folding provides further temperature to intercept, thereby should be folding helps making transmission of heat minimum between wheel hub and the brake disc in conclusive mode.
The lath of the horizontal expansion by L shaped or T shape element is realized the axial position of determining of each intermediary element respectively in simple mode.
In addition, the folded portions of each intermediary element can be the elasticity pretension, thus the elasticity by folding principle and each intermediary element in combination between brake disc and the wheel hub, promptly between ring gear and external toothing, obtain resistance of heat transfer every with the better compensation of tolerance of size.
According to another form of implementation, in the moving part at least one taken of wheel hub is provided with the outstanding flange portion of radially outward, this flange portion will be installed in brake disc on the wheel hub towards a side shaft to fixing.The one protuberance synergy of flange portion and brake disc, this protuberance forms by the step on interior week.Therefore, even under high load, after the operation of long period, also still easily can dismantle brake disc from wheel hub.
Each intermediary element can be passed through the spring element axial restraint, and wherein each spring element has a spring fin that is fixed on the flange taken on the moving part and extends in both sides, and this spring fin is bearing on the intermediary element of attaching troops to a unit.
By the utility model will the high rubbing surface of when braking heat load be braked power consumingly the supporting element of mechanical load separate.This is also supported in this wise, be each supporting element be provided be used for cooling air, to the input pipeline of air passageways, this air passageways forms at interval by each, these are produced synergistically by the layout that separates and the meeting stile of two friction rings at interval, and wherein each input pipeline is basically by radially forming in the hole that brake disc extends.
According to another conception regulation of the present utility model, brake disc is 180N/mm by minimum tensile strength
2Gray cast iron constitute.
Wheel hub can be made by the spheroidal graphite ingot bar, and it has 500N/mm
2Minimum tensile strength at least 9% specific elongation, perhaps 600N/mm simultaneously
2Minimum tensile strength and at least 5% specific elongation.
New brake disc constitutes, and makes the bottom of corresponding supporting element in that to constitute side in the transition region of the bottom surface of the adjacency of the teeth groove that forms recessed, and this side is recessed to have the profile of spill and not processed to keep casting surface.
Should can bear the high tensile stress that when braking, exists from the teeth outwards especially by the casting surface harder with respect to base material.
Set in addition, brake disc mirror image in each plane constitutes symmetrically, thereby can install on independent of direction ground without a doubt.
In addition, the radial height of corresponding supporting element is 19-22mm, preferred 20.5mm from the inside radius of corresponding rubbing surface.Reduce effective compressive load per unit area thus, make the number of supporting element to be reduced to minimum, obtain the cost advantage thus naturally, particularly because must use corresponding less intermediary element and spring element.
The beneficial effects of the utility model are to improve the working life of brake disc and the installation and removal of simplifying brake disc with the expense on the structural and manufacturing technology seldom.
