Abstract
The invention provides a full-floating type half shaft and hub system fixed without a flange or a screw. The size of a hub of an existing vehicle does not need to be changed, only a key groove needs to be machined in the inner hole face adjacent to the outer fracture surface of the hub to form a spline sleeve, meanwhile, the flange in the direction of a transmission shaft flange plate is removed, and the length of a half shaft is reduced to the length slightly smaller than the length of the outer end face of the hub; a spline shaft matched with the spline sleeve of the hub is machined on a shaft at an original flange end, the center of the outer end face of the spline shaft can be punched and tapped into a thread so that the half shaft can be easily dismounted; due to the fact that the total torsion acting area between the spline sleeve manufactured on the hub and the spline shaft is far larger than the stress area of the half shaft fixed through the screw, the half shaft can be fixed without the screw, and meanwhile the outer surface of the hub is not fixedly provided with the half shaft flange any more instead of an end cover irrelevant to the half shaft. Thus, the fault of the half shaft and hub system due to loosening, falling and fracturing of the half shaft screw cannot happen any more.
Description
(1) technical field
The invention provides and a kind of can apply to various vehicle, it is impossible to the blue full floating automobile half-axle fixed without screw and hub system.
(2) technical background
One end that traditional vehicle fully floating axle is connected with differential mechanism is spline, and the one end being connected with wheel hub (another name spindle nose) is flange, flange has screw hole, is realized the link of half shaft flange wheel hub (another name spindle nose) by screw.This ring flange (flange) that is screwed realizes the mode of transmission, especially many heavy-duty vehicles and the engineering truck etc. fallen back that frequently advances after vehicle uses a period of time, slightly causing connecting screw easily rupture and loosen owing to using environment to dislike, causing vehicle to cast anchor cannot walk.Its main cause is one direction high pulling torque or the active force of twocouese high pulling torque, according to torsion direction, the threaded interior hole caused defines that aperture is unilateral or being gradually increased of bilateral from inside to outside, and then add the shaking amplitude of king bolt, ultimately result in screw and nut loosen drop or cause screw to fracture because of work fatigue, formed vehicle trouble.
(3) summary of the invention
nullThe hub size of existing vehicle can not be done any change (we the most do not oppose to carry out wheel hub and semiaxis as required the design of dimensional structure improvement certainly) by the present invention as required，Only by processing keyway formation spline housing in the inner hole surface adjacent at section outer with wheel hub，The flange in transmission shaft flange dish direction is removed simultaneously，By the length reduction of semiaxis to being slightly less than the length arriving wheel hub outer face，And on the axle of original flange end, process the splined shaft matched with wheel hub spline housing，Can punch at this outer end of splined shaft center and screw thread is made in tapping，It is beneficial to the dismounting of semiaxis，Due to the spline housing made on wheel hub，And between splined shaft，Total twisting force area is far longer than，The semiaxis lifting surface area being screwed，Again because this semiaxis is fixed without screw，So this semiaxis will not occur that axle shaft screw loosens the fault caused that drops and rupture again.This kind of structure makes the ring flange outside wheel hub separate with semiaxis and becomes end cap, although making spline housing in wheel hub to define the keyway of a few millimeters deep, but owing to the end cap in outside is not subjected to torsion, with the least screw can realize forever not dropping fixing, so several millimeters of designs that can realize punching tapping are moved gently towards the direction that diameter increases in the center of screw hole, the normal mounting that can meet end cap completely is fixed and uses safety.
(4) accompanying drawing explanation
Fig. 1 is fully floating axle and the hub system structure chart of the present invention
(5) specific implementation method
If Fig. 1 is fully floating axle and the hub system structure chart of the present invention, in figure, 1 is the section of wheel hub；2 is wheelboss flange, is provided with screw for fixing brake disc (brake hub) and wheel；3 wheel hub outer faces, are that old-fashioned flanged disc type suspends semiaxis entirely, and for fixing the outer face of semiaxis ring flange, here this wheel hub outer face is served only for fixing end cap；4 is hub interior annular retaining ring groove, fixes bearing use for placing back-up ring；5 is the position that former hub oil seal is installed；6 is hub bearing installation site (hub spindle bearing)；The installing space (space namely needed for the nut and locking plate installation of fixing bearing in rear axle case hub spindle bearing) that 8 is the upper nut and locking plate (stop pad) for installing stationary hub of rear axle case far-end (axle sleeve)；This space is the useful space by carrying out process of axle shaft acquisition, the bulk processing being specifically actually needed according to nut and locking plate.9 is power transmission shaft profile；Also have in the middle of semiaxis and wheel hub be connected with back axle for stationary hub parts of bearings (rear axle case far-end hub spindle bearing and the fixing screw thread of bearing inner race), nut locking plate is installed on the components and can realize the fixing of wheel hub, owing to these parts are not that the present invention improves the part related to, figure is not drawn into also be not described at this.7 is the splined shaft that formed of semiaxis and wheel hub and spline housing working occlusion sectional schematic diagram.
Owing to connecting between the splined shaft parts and the semiaxis that process on semiaxis needs certain intensity, therefore the coupling part for placing nut locking plate annular groove space Yu semiaxis made on semiaxis, the thinnest place is also required to certain thickness, to ensure that semiaxis meets or exceeds the intensity of needs, therefore the outside threadless part of residue also needing to the nut locking plate by being used for stationary hub removes the length (i.e. the inefficient length of 10 millimeter is respectively removed at rear axle case two ends) of certain millimeter, in order to meet the bonding strength (thickness) between semiaxis and splined shaft.Splined shaft on semiaxis and wheel hub and spline housing, its length can be equal to or less than the two the maximum allowable length of inner surface, as marked in 7 in Fig. 1.Additionally splined shaft spline length might be less that hub inner surface length.The spline housing processed on wheel hub can be with wheel hub one, it is also possible to welds with different materials or identical material or inlays up.Wheel hub material therefor can be one or more in the materials such as cast iron, wrought iron, steel.When splined shaft combines with semiaxis, if wheel hub spline housing intensity is sufficiently high, the length that splined shaft matches with wheel hub spline housing can also be made the shortest, namely spline length need not stretch out again formation hub nut locking plate install ring-shaped groove, i.e. ringless-type groove splined shaft.If the design about end cap is not desired to remove the inefficient length (namely rear axle case two ends hub spindle bearing part outside the screw thread that bearing is fixed) of the axle sleeve for stationary hub, it would however also be possible to employ protruding end cover designs.
The present invention is a kind of fully floating axle fixing without flange and screw and hub system, it is characterised in that the splined shaft that connecting through between semiaxis and wheel hub is separately positioned on semiaxis and wheel hub and spline housing realize the transmission of power；Native system wheel hub is provided with end cap, the method being designed to use original semiaxis flange screw fixing of the end cap of the present invention；Another implementation of the end cap of the present invention is utilized in hub outside surface formulated external threads, configures the design of matched female thread on end cap simultaneously；The shape of the end cap of the present invention can use the shape of former half shaft flange；Another design of the end cap of the present invention is that the end cap of the present invention can use mid portion to have the design of projection；The semiaxis of the present invention can be made with one piece of integral material；Semiaxis another program of the present invention is that this axle can be made with different materials combination；Spline housing on the wheel hub of the present invention and wheel hub can be made with one piece of integral material；Spline housing another embodiment on the wheel hub of the present invention and wheel hub is that the spline housing on wheel hub and wheel hub can be made with different materials combination, the connection between different piece can use welding, inlay, dock, butt welding, the method realization of excessively cooperation.
nullOwing to the hub size of existing vehicle can not be done any change by the present invention as required，Only by processing keyway formation spline housing in the inner hole surface adjacent at section outer with wheel hub，The flange in transmission shaft flange dish direction is removed simultaneously，By the length reduction of semiaxis to being slightly less than the length arriving wheel hub outer face，And on the axle of original flange end, process the splined shaft matched with wheel hub spline housing，Can punch at this outer end of splined shaft center and screw thread is made in tapping，It is beneficial to the dismounting of semiaxis，Due to the spline housing made on wheel hub，And between splined shaft，Total twisting force area is far longer than，The semiaxis lifting surface area being screwed，Again because this semiaxis is fixed without screw，This kind of structure makes the ring flange outside wheel hub separate with semiaxis and becomes end cap simultaneously，So this semiaxis will not occur that axle shaft screw loosens the fault caused that drops and rupture again.
