Description
Technical field
The utility model relates to automatic transmission correlative technology field, refers in particular to a kind of clutch anti-rotation mechanism.
Background technique
Automatic transmission, also known as automatic transmission case, is as a rule a kind of automotive transmission that automatically can change gear ratio in vehicle travel process, thus makes driver need not hand shift, also for main equipment railway locomotive.In the flywheel casing of clutch between motor and gearbox, be fixed on the back plane of flywheel with screw by clutch assembly, the output shaft of clutch is exactly the input shaft of gearbox.In vehicle traveling process, driver can step on as required or release the clutch pedal, and motor and gearbox is temporarily separated and engages gradually, to cut off or to transmit the power that motor inputs to speed changer.In the clutch configuration of existing automatic transmission, because bearing larger torque, and easily there is torsional deflection, even breakage phenomenon in the return spring of 03 clutch (clutch of one of them), thus affect the closed of clutch and be separated, finally affect the normal work of clutch.In prior art, realized anti-rotational by structure characteristic, but if once stressed comparatively large, rotating speed is higher, anti-rotationally namely loses efficacy, return spring skids distortion.
Chinese patent Authorization Notice No.: 0N 2861604Y, authorized announcement date on January 24th, 2007, disclose a kind of adjustment-free clutch, it is characterized in that: on platen, be fixed with concavo-convex profile of tooth adjustment ring A, concavo-convex profile of tooth adjustment ring B is corresponding with adjustment ring A to be engaged, extension spring is hung with between adjustment ring B and adjustment ring A, diaphragm spring and support ring are riveted and are fixed in lid, diaphragm spring outer is pressed on adjustment ring B outward edge, spacing jam plate one end is fixed in adjustment column, spacing jam plate the other end head is stuck in adjustment ring B outward edge gap, adjustment column one end is fixed on and covers, the adjustment column the other end is plugged in platen groove by spring A.The deficiency of this model utility is, if once stressed comparatively large, rotating speed is higher, anti-rotationally namely loses efficacy, spring skids distortion.
Model utility content
The utility model there is above-mentioned deficiency to overcome in prior art, provides a kind of clutch anti-rotation mechanism that effectively can prevent relatively rotating.
To achieve these goals, the utility model is by the following technical solutions:
A kind of clutch anti-rotation mechanism, comprise clutch external tooth hub and clutch plunger, described clutch plunger is arranged on the inside of clutch external tooth hub, some positioning rods are provided with between described clutch external tooth hub and clutch plunger, one end of described positioning rod is fixedly mounted on clutch external tooth hub, and the other end and the clutch plunger of described positioning rod are slidably connected.
Coordinate after complete clutch is installed, when clutch plunger moves, under spacing between above-mentioned positioning rod, clutch external tooth hub and clutch plunger three, clutch plunger can be free to slide along positioning rod, but clutch plunger can not rotate relatively with clutch external tooth hub, such design reaches the object that can effectively prevent from relatively rotating, and namely starts anti-rotational function.
As preferably, the shape of cross section of described positioning rod is convex shape, described clutch external tooth hub is provided with the external tooth hub boring corresponding with positioning rod, and described clutch plunger is provided with the piston boring corresponding with positioning rod, and the aperture of described external tooth hub boring is less than the aperture of piston boring.The position of positioning clutch external tooth hub and clutch plunger is convenient in such design, thus facilitates the installation of positioning rod.
As preferably, the part that described positioning rod is arranged on clutch external tooth hub is consistent with the aperture that external tooth hub is holed, and other parts of described positioning rod are consistent with the aperture that piston is holed.Such design greatly facilitates positioning rod and is installed on clutch external tooth hub, and the installation contributing to positioning rod is fixed.
As preferably, one end that described positioning rod is arranged on clutch plunger inside is provided with position-limit mechanism, described position-limit mechanism comprises spacing steel ball and limit spring, described positioning rod is provided with the spacing hole for position-limit mechanism, the shape of cross section of described spacing hole is waist shaped hole shape, described spacing steel ball has two two ends being placed in spacing hole respectively, and described limit spring is placed in the centre of two spacing steel balls.Be convenient to spacing for positioning rod on clutch plunger, prevent positioning rod disconnecting clutch piston and affect the use of clutch, causing the skidding of return spring in clutch to be out of shape.
As preferably, described positioning rod and clutch external tooth hub are by punching press or be welded to connect.Structure is reliable, and intensity is better.
The beneficial effects of the utility model are: even if also can prevent relative rotation at high speeds, and in protection clutch, return spring does not stress distortion, effectively prevents relative rotation, conveniently install, and reliably, intensity is better for structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation at A place in Fig. 1.
In figure: 1. clutch external tooth hub, 2. clutch plunger, 3. positioning rod, 4. spacing steel ball, 5. limit spring, 6. spacing hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as described in Figure 1, a kind of clutch anti-rotation mechanism, comprise clutch external tooth hub 1 and clutch plunger 2, clutch plunger 2 is arranged on the inside of clutch external tooth hub 1, some positioning rods 3 are provided with between clutch external tooth hub 1 and clutch plunger 2, one end of positioning rod 3 is fixedly mounted on clutch external tooth hub 1, and positioning rod 3 and clutch external tooth hub 1 are by punching press or be welded to connect, and the other end and the clutch plunger 2 of positioning rod 3 are slidably connected.Wherein: the shape of cross section of positioning rod 3 is convex shape, clutch external tooth hub 1 is provided with the external tooth hub corresponding with positioning rod 3 and holes, clutch plunger 2 is provided with the piston corresponding with positioning rod 3 and holes, the aperture of external tooth hub boring is less than the aperture of piston boring, the part that positioning rod 3 is arranged on clutch external tooth hub 1 is consistent with the aperture that external tooth hub is holed, and other parts of positioning rod 3 are consistent with the aperture that piston is holed.As shown in Figure 2, one end that positioning rod 3 is arranged on clutch plunger 2 inside is provided with position-limit mechanism, position-limit mechanism comprises spacing steel ball 4 and limit spring 5, positioning rod 3 is provided with the spacing hole 6 for position-limit mechanism, the shape of cross section of spacing hole 6 is waist shaped hole shape, spacing steel ball 4 has two two ends being placed in spacing hole 6 respectively, and limit spring 5 is placed in the centre of two spacing steel balls 4.
