Description
Technical field
The utility model belongs to automotive transmission technical field, relates to a kind of positioning device of gear sleeve of automobile synchronizer.
Background technique
Automotive transmission is a set of for coordinating the speed change gear of the rotating speed of motor and the actual travel speed of wheel, for bringing into play the optimum performance of motor.Speed changer can, in vehicle traveling process, produce different gear ratio between motor and wheel, can make engine operation under its best power performance state by gearshift.Because transmission input shaft and output shaft are with speed rotation separately, two different gears of rotational speed engage by force impact will inevitably occur, and damage gear.Therefore in speed changer, all can be provided with synchronizer.Synchronizer is exactly the friction plate of arranging on combined cover and gear train, different from general friction plate, and its rubbing surface is taper.The effect of this group friction plate is before the vertical tooth of straight-tooth and disk contacts; rub in advance; a side's larger rotating speed energy is passed to the side that rotating speed is less; make the side that rotating speed is less promote rotating speed; reach a side synchronization larger with rotating speed; so not only can guarantee normal gearshift, can also play the effect of buffering.Synchronizer has generally comprised tooth hub and tooth cover, and tooth cover is set on tooth hub and by spline engagement, is provided with slide block and carries out axial location between tooth hub and tooth cover.
Chinese utility model patent application (200920310591.7) discloses the synchronizer run-resistant mechanism in a kind of AE field, comprise: synchronizing ring, tooth hub, tooth cover and integrated slider, wherein: integrated slider is arranged at the outer of tooth hub, integrated slider and the clamping of tooth cover phase, tooth hub and tooth cover socket-connect, and are socketed in the both sides of tooth cover the synchronizing ring Mirror Symmetry of two same structures.When this device has been eliminated gearshift in simplified structure, deviate from tooth cover because of the steel ball of integrated slider and affect the situation generation that even synchronizer lost efficacy of shifting gears.But current generally popular double-clutch speed changer, double-clutch speed changer proposes higher requirement to the neutral gear positioning performance of synchronizer, if double-clutch speed changer only adopts above-mentioned positioning sliding block to position tooth cover, its stationkeeping ability cannot meet double-clutch speed changer.
For this reason, between the tooth hub of synchronizer and tooth cover, increase by one group of positioning device technician, this positioning device has been offered locating slot on the inner side surface of tooth cover, on the outer circumferential face of tooth hub, offer mounting hole, in mounting hole, plug the spring seat of a tubular, one steel ball and a spring are set in spring seat, compress steel ball by spring and make steel ball compress locating slot, tooth cover is positioned.But because spring seat is plugged in mounting hole, between itself and mounting hole inwall, certainly exist certain gap, and parts in gearbox are in the state of running up, therefore spring seat there will be play displacement, although this play displacement is less, the motion size of the assemblies such as shift fork is also to have certain error, in the time that these motion sizes are superimposed, will cause gear clear not, affect shifting comfort.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of positioning device of gear sleeve of automobile synchronizer, and the positioning device of this gear sleeve of automobile synchronizer can make the fixing more firm of spring seat, thereby improves the stationkeeping ability to tooth cover.
The purpose of this utility model can realize by following technical proposal: a kind of positioning device of gear sleeve of automobile synchronizer, synchronizer comprises tooth hub and tooth cover, described tooth cover is set on tooth hub, described positioning device comprises the some locating slots that are circumferentially opened on tooth cover inner side surface, on the outer circumferential face of tooth hub, offer some mounting holes with locating slot relative position, it is characterized in that, in described mounting hole, be inserted with a tubular spring seat, on the outer side wall of spring seat, there is outside thread, on the inwall of mounting hole, there is internal thread, spring seat is fixed in mounting hole by screw-thread fit, in described spring seat, be provided with a spring and a steel ball, one end of spring is pressed on the bottom surface of spring seat, the other end is pressed on steel ball.
When in neutral state, tooth cover is set on tooth hub, locating slot is relative with spring seat, steel ball in spring seat is pressed in locating slot under the elastic force effect of spring, in the time that axial float power appears in tooth cover, the sidewall of locating slot can act on steel ball and make steel ball Compress Spring, and the elastic force of spring increases and makes steel ball produce reverse axial force to cell wall, stop the axial float of tooth cover, improve the stationkeeping ability of tooth cover; Spring seat is connected in mounting hole by thread helix, and the gap between mounting hole has been eliminated in fixation, not only can improve the stationkeeping ability to tooth cover, and can improve the travelling comfort while gearshift.
In the positioning device of above-mentioned gear sleeve of automobile synchronizer, described spring seat axially and wheel hub radially consistent, on the opening end end face of spring seat, there are two cylindric projections, the axle center of the relative spring seat of this two projection is symmetrical arranged.The elastic force of spring radially front passes to steel ball, and steel ball is more even to the active force of locating slot; Clamping application of force when projection is used for rotating missile spring abutment, facilitates the dismounting of spring seat.
In the positioning device of above-mentioned gear sleeve of automobile synchronizer, on the inner side surface of described tooth cover, be circumferentially evenly equipped with some splines, on the outer circumferential face of described tooth hub, be circumferentially evenly equipped with some keyways, above-mentioned locating slot is opened on spline end face, and mounting hole is opened on keyway bottom surface.Mounting hole has certain degree of depth, if be opened on spline, will weaken the mechanical strength of spline, is therefore opened on the bottom surface of keyway.
In the positioning device of above-mentioned gear sleeve of automobile synchronizer, described locating slot is a spherical groove.The spherical radius of this spherical groove is consistent with the radius of steel ball, and when steel ball is pressed in locating slot, the inwall of spherical groove can be completely and steel ball surface laminating.
In the positioning device of above-mentioned gear sleeve of automobile synchronizer, the quantity of described mounting hole is three, and these three mounting holes are circumferentially uniformly distributed.Mounting hole quantity can weaken the mechanical strength of tooth hub too much, obvious not to the locating effect of tooth cover very little; Be uniformly distributed the active force making tooth cover more even, improve position stability.
In the positioning device of above-mentioned gear sleeve of automobile synchronizer, described spring seat adopts metal stamping formed.Processing technology is simple, and cost of production is low.
Compared with prior art, the positioning device of this gear sleeve of automobile synchronizer has the following advantages:
1, because spring seat is threaded connection in mounting hole, therefore fixation, has eliminated the gap between mounting hole, not only can improve the stationkeeping ability to tooth cover, and can improve the travelling comfort while gearshift.
2, owing on the opening end end face at spring seat, projection being set, in the time of spring seat dismounting, clamping application of force when this projection is used for rotating missile spring abutment, therefore dismounting is convenient.
3,, because locating slot is a spherical groove, when therefore steel ball is pressed in locating slot, the inwall of spherical groove can be completely and steel ball surface laminating.
