Description
Technical field
The utility model belongs to automobile gearbox technical field, relates to a kind of positioning device of gear sleeve of automobile synchronizer.
Background technique
The output speed of motor is very high, and peak output and Maximum Torque occur in certain rotating speed district.In order to bring into play the optimum performance of motor, just must there is a set of speed change gear, coordinate the actual travel speed of rotating speed and the wheel of motor.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, when conversion gear, close " synchronously " problem that exists.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 ensure 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.
As 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 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.
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 stationkeeping ability to tooth cover when the positioning device of this gear sleeve of automobile synchronizer can improve neutral position state makes gearshift sense more clear.
The purpose of this utility model can realize by following technical proposal: a kind of positioning device of gear sleeve of automobile synchronizer, described synchronizer comprises tooth hub and is set in the tooth cover on tooth hub, it is characterized in that, described positioning device is included on the inner side surface of tooth cover and circumferentially offers some locating slots, on the outer circumferential face of described tooth hub, circumferentially offer some mounting holes, described mounting hole axially and tooth hub radially consistent, in mounting hole, be provided with a steel ball, between the bottom surface of described mounting hole and steel ball, be provided with and can promote steel ball and be pressed on the spring in above-mentioned locating slot.
The cell wall of locating slot is arc-shaped concave, can match with steel ball; Spring is arranged in mounting hole, and when neutral position state, steel ball half is in mounting hole, and spring one end is pressed on steel ball, and its elastic force promotes steel ball and is pressed in locating slot; 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, stops the axial float of tooth cover, improves the stationkeeping ability of tooth cover.
In the positioning device of above-mentioned gear sleeve of automobile synchronizer, in described mounting hole, be inserted with a tubular spring seat, above-mentioned spring and steel ball are arranged in spring seat, and one end of described spring is pressed on the bottom surface of spring seat, and the other end is pressed on steel ball.Spring and steel ball are arranged in mounting hole by spring seat, improve the stability of spring and steel ball, simultaneously easy maintenance and replacement.
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, the opening end end face of described spring seat flushes with keyway bottom surface.When tooth cover is set on tooth hub, spline need to coordinate with keyway, and the opening end end face of spring seat flushes with keyway bottom surface, avoids spring seat and spline to produce and collides with.
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.
Compared with prior art, the positioning device of this gear sleeve of automobile synchronizer has the following advantages:
1, because tooth hub increases axially locating ability by steel ball and spring to tooth cover, therefore can stop the axial float of tooth cover, improve the stationkeeping ability of tooth cover, make gearshift sense more clear.
2, because spring and steel ball are arranged in mounting hole by spring seat, therefore the structure of spring and steel ball is more stable, maintenance simultaneously with change convenient.
3, because the opening end end face of spring seat flushes with keyway bottom surface, therefore can avoid spring seat and spline to produce and collide with, improve the global stability of synchronizer.
