Abstract
A split type thrust gasket structure comprises a thrust gasket and a shaft with a clamping groove, wherein the thrust gasket adopts a split structure and is composed of two semi-annular gaskets which are embedded in the clamping groove in a matched manner. When the thrust gasket structure is in use, the two semi-annular gaskets are mounted in the clamping groove of the shaft to bear bidirectional axial forces; ring-shaped retaining rings are arranged on the outer sides of the two semi-annular gaskets to prevent the thrust gasket from separation under the centrifugal force action of the shaft in high speed revolution. The thrust gasket structure can bear the bidirectional axial forces without snap rings or other limiting parts on the shaft, and avoids the situation that the shaft is lengthened due to axial adding of limit structures, so that a transmission is more compact in structure to facilitate the spatial arrangement in the whole vehicle. The thrust gasket structure has the advantages of simple structure and easiness in realization, and can be applied to axial spacing of the parts on the shaft.
Description
Technical field
The utility model relates to a kind of automotive transmission technology, particularly a kind of for the split type thrust pad structure on automotive transmission.
Background technique
At present, on automotive transmission, extensive use is integrated type thrust pad, and this thrust pad is more in the shaft shoulder place application of single load bearing, is used for speed changer one side of keeping off and reverse gear, and can bear larger axial force, prevents end face ablation.But the in the situation that of bidirectional stress, axially must increase limit structure, as the structures such as snap ring and annular groove carry out spacing, thereby strengthened axial dimension.Application number is that 200820086182.9 patent document discloses a kind of automotive transmission five and keeps off thrust washer, described structure consists of thrust washer, stop steel ball and snap ring, be arranged on the input shaft between four gear driving gears and five gear driving gears, thrust washer relies on the snap ring being arranged in draw-in groove to bear unidirectional axial force.If this structure thrust washer need to bear two-way axial force, to increase again snap ring or other spacing part is spacing to thrust washer, like this, increased axle upper limit part, simultaneously with the increase of using part, axle, also in requisition for lengthening, increases the boundary dimension of speed changer, is unfavorable for car load space layout.
Model utility content
The purpose of this utility model is the drawback for prior art, and the split type thrust pad structure that a kind of axial dimension is little and can bear bidirectional axial force is provided.
Problem described in the utility model realizes with following technical proposals:
A kind of split type thrust pad structure, specialization is, and it comprises thrust pad and axle, and axle is provided with draw-in groove, and described thrust pad is Split type structure, it is comprised of two semi-circular pads, two involutory being inlaid in draw-in groove of semi-circular pad.
Above-mentioned split type thrust pad structure, described structure is also provided with and keeps circle, keeps circle for ring, keeps circle coupling to be sleeved on two semi-circular pad outsides.
Above-mentioned split type thrust pad structure, the thickness of described thrust pad is greater than the thickness 0.5-1 millimeter that keeps circle.
Above-mentioned split type thrust pad structure, the thickness of described thrust pad is less than the width dimensions 0.05-0.1 millimeter of draw-in groove.
The utility model bears bidirectional axial force problem for solution thrust pad and improves on the basis that does not increase axial dimension, has designed a kind of split type thrust pad structure.This structure comprises that thrust pad and a ring that two semi-circular pads form keep circle, two semi-circular pads are arranged in the draw-in groove on axle, bear bidirectional axial force, ring keeps snare in two semi-circular pad outsides, avoids the effect of axle centrifugal force when High Rotation Speed that thrust pad is separated.Thrust pad of the present utility model just can be realized and bear bidirectional axial force without snap ring or other axle upper limit part, avoid increasing the length dimension of axle because axially increasing limit structure, thereby make speed changer structure compacter, the space that speed changer is more conducive in car load is arranged.The utility model is simple in structure, be easy to realize, and can be widely used in the axial limiting of parts on shaft.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 left view;
Fig. 3 is that the utility model is used view.
In figure, each list of reference numerals is: 1, keep circle, 2, thrust pad, 3, axle, 4, draw-in groove, 5, four gear driving gears, 6, three gear driving gears, 7, transmission input shaft.
Embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises maintenance circle 1, thrust pad 2 and axle 3, and axle is provided with draw-in groove 4.Thrust pad 2 is Split type structure, and it is comprised of two semi-circular pads, and two semi-circular pads are inlaid in draw-in groove 4 synthetic ring.For avoiding the axle effect of centrifugal force when rotated that thrust pad is separated and thrown away, the maintenance circle coupling of ring is sleeved on to two semi-circular pad outsides, keep enclosing the position-limiting action to thrust pad.In use, thrust pad can bear the axial force of both direction, and for improving the working life of thrust pad, thrust pad need to pass through Q-tempering processing.The maintenance circle that is enclosed within thrust pad outside only plays position-limiting action, keeps circle not bear axial force, generally through quenching with Subsequent tempering.According to above-mentioned handling characteristics, the thickness of thrust pad 2 is greater than the thickness 0.5-1 millimeter that keeps circle.Thrust pad is arranged in draw-in groove 4, and it will guarantee to be convenient to the requirement of assembling, can not in draw-in groove, have again larger play, and the thickness size of thrust pad is less than the width dimensions 0.05-0.1 millimeter of draw-in groove.
With reference to figure 3, the utility model is arranged on transmission input shaft 7 while being used for automotive transmission, between three gear driving gears 6 and four gear driving gears 5, its effect is as follows: when speed changer is hung into three gear towing aheads, the suffered axial force left of three gear driving gears 6, three gear driving gears make thrust pad contact with draw-in groove left side on transmission input shaft, now thrust pad 2 plays axial limiting effect to three gear driving gears, avoids four gear driving gears 5 to produce pressure and cause four gear driving gear ablations; When speed changer is hung into four gears are anti-while dragging, the suffered axial force to the right of four gear driving gears 5, four gear driving gears make thrust pad 2 contact with draw-in groove right side on transmission input shaft, now thrust pad plays axial limiting effect to four gear driving gears 6, avoids three gear driving gears to produce pressure and cause three gear driving gear ablations.When thrust pad turns round together with transmission input shaft, keep snare to a two semicircle annular gasket outer end, overcome the centrifugal force of two semicircle annular gaskets, prevent its separation.
