Description
Technical field
The utility model belongs to field of mechanical technique, and the tooth sleeve anti-drop relating to a kind of automobile synchronizer falls structure.
Background technique
Because transmission input shaft and output shaft rotate with respective speed, and two different gears of rotational speed engage by force impact will inevitably occur, and damage gear, therefore there is the problem of " synchronously " when converting gear.The gearshift of old-fashioned speed changer mainly adopts the mode of " bipod clutch ", and upshift in neutral gear position stop for a moment, downshift will at neutral gear position open out, and to reduce the speed discrepancy of gear, this operates more complicated, is difficult to grasp accurately.In order to solve the problem, the inside configuration of existing automotive transmission is equipped with an important equipment, i.e. synchronizer.The Main Function of synchronizer makes to reach consistent rotating speed and engage smoothly by meshed gears, can effectively avoid hanging do not perform, gear whine etc. when eliminating gearshift.
As Chinese patent application (application number: 200910307120.5) disclose a kind of synchronizer with Anti-extrusion integrated slider, comprise in conjunction with tooth, synchronizing ring, tooth hub, tooth cover and integrated slider, integrated slider is arranged at the outer of tooth hub, uniform some slide block slots on tooth hub, slide block is installed in the slide block slot of tooth hub; Interior edge uniform some steel-ball grooves respectively of tooth cover, integrated slider is connected in the steel-ball groove of tooth bar; Synchronizing ring and the both sides being socketed in tooth cover in conjunction with tooth successively from inside to outside of two groups of same structures Mirror Symmetry.Synchronizer is arranged according to gear can be divided into bilateral synchronous device and Unilateral synchronizer.In existing Unilateral synchronizer, there will be tooth cover during assembling and hold caducous problem, the efficiency of impact assembling.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, and the tooth sleeve anti-drop proposing a kind of automobile synchronizer falls structure, and its technical problem to be solved is: existing Unilateral synchronizer tooth cover when assembling easily comes off, the efficiency of impact assembling.
The purpose of this utility model realizes by following technical proposal: a kind of tooth sleeve anti-drop of automobile synchronizer falls structure, automobile synchronizer comprises tooth cover, slide block and tooth hub, described tooth hub to be arranged in tooth cover and to be connected by spline fitted between overlapping with tooth, on described tooth hub, circumference is evenly equipped with some slide block slots, and the internal surface circumference of described tooth cover is evenly equipped with some corresponding slots to make way; Described slide block is arranged in described slide block slot and end is connected in slot to make way, it is characterized in that, this tooth sleeve anti-drop structure that falls comprises limiting stopper on the cell wall being installed in described slide block slot, and described limiting stopper is arranged in the side of described slide block and can comes off from slide block slot with the slide block anti-limited slip block that leans.
During automobile synchronizer assembling, by being arranged on the effect of the limiting stopper of slide block side, can for slide block against, block the movement of slide block, anti-limited slip block comes off from slide block slot, and slide block is then connected in the slot to make way of tooth cover, then the movement of tooth cover can be blocked, play spacing effect, efficiently solve tooth cover in assembly process and hold caducous problem, improve the efficiency of assembling.
Fall in structure at the tooth sleeve anti-drop of above-mentioned automobile synchronizer, described slide block comprises steel ball, spring and fixture block, and described steel ball, spring and fixture block are integral type structure, and described steel ball is connected in the slot to make way of tooth cover; Described spring and fixture block are all located in described slide block slot, and described limiting stopper is positioned at the side of fixture block and can leans with fixture block.During assembling, limiting stopper can lean with fixture block, thus blocks the movement of slide block, and anti-limited slip block comes off from slide block slot.
Fall in structure at the tooth sleeve anti-drop of above-mentioned automobile synchronizer, the thickness of described limiting stopper is 2 ~ 3mm.The thickness of limiting stopper is too thin, then the limit effect played is poor, is not enough to restriction tooth cover coming off with slide block; The thickness of limiting stopper is too thick, then can affect again the integral layout of tooth cover and tooth hub.The thickness of limiting stopper is arranged in the scope of 2 ~ 3mm, best results.
Fall in structure at the tooth sleeve anti-drop of above-mentioned automobile synchronizer, described limiting stopper and described tooth hub are integral type structure.In the process making tooth hub, when only need offer slide block slot on tooth hub, retain limiting stopper, more for convenience.
Fall in structure at the tooth sleeve anti-drop of above-mentioned automobile synchronizer, described limiting stopper is welded on the cell wall of described slide block slot.Limiting stopper is also directly fixed on the cell wall of slide block slot by welding, and easily makes.
Compared with prior art, the tooth sleeve anti-drop of this automobile synchronizer structure that falls has the following advantages:
1, by the effect of limiting stopper, the movement of slide block can be blocked, then can play the effect of restriction tooth cover movement, efficiently solve tooth cover in assembly process and hold caducous problem, improve the efficiency of assembling.
2, the thickness of limiting stopper is moderate, and guarantee can limit tooth cover coming off with slide block again while can not affecting the integral layout of tooth cover and tooth hub well.
3, structure is simple, easy to make, and be applicable to the automobile synchronizer of various vehicle, versatility is good.
