Description

Isolator with floating slide block for starter

Technical Field

The utility model relates to a part on the automobile starter, concretely relates to isolator of slider floats in starter area.

Background

The one-way clutch in the starter is an intermediary component for transmitting the mechanical energy generated by the working of the starter motor to the engine gear ring to start the engine. During the whole starting process, the work cycle of the isolator is as follows: under the action of external force, the gear ring is engaged with the gear ring; when the starting motor works, the gear ring is driven to rotate through the isolator; when the rotating speed of the engine rises to a certain limit after the engine is started, the overrunning of the isolator is realized; and finally, the isolator is withdrawn to the original position.

In the process of actual work, the isolator is sleeved on an electric drive shaft through spiral teeth, a driving gear on the isolator body is located in the process of meshing and matching of a gear ring of an engine, the isolator is pushed upwards and is mainly pried through a shifting fork, one end of the shifting fork is connected with the movable end of an electromagnetic switch, the shifting fork is used for prying the isolator, as the fulcrum of the middle position of the shifting fork is fixed, the shifting fork is in contact with the stressed surface of the isolator and in the prying process, the contact point of the shifting fork and the isolator has a shifting process, abrasion can be caused to the end part of the shifting fork, after the service life is prolonged, the meshing and matching of the driving gear on the isolator and an engine flywheel is not tight enough, and the starting efficiency is influenced.

Disclosure of Invention

In order to solve the problem, an object of the present invention is to provide an isolator with a floating block for a starter with reliable and stable transmission, which avoids the wear of a shifting fork in operation.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides an isolator of unsteady slider in starter area, includes the isolator body, isolator body one end be drive gear, its other end is the sleeve pipe, drive gear one end forms the great and annular cooperation portion of being of external diameter with the cooperation of sleeve pipe one end loose ground cover has unsteady slider on the sleeve pipe, the hole of unsteady slider with leave the clearance of floating between the sleeve pipe outer wall be equipped with on the outer wall of unsteady slider with shift fork normal running fit's lug.

A buffer spring is arranged between the floating slider and the matching part.

The sleeve is sleeved with a movable baffle which is arranged between the buffer spring and the floating slide block.

And the floating sliding block is provided with an abutting groove matched with the baffle.

The position of the sleeve close to the end part of the sleeve is also connected with a limit stop ring.

The sleeve pipe on still be equipped with the slide periphery wall on be equipped with annular draw-in groove, the slider hole cover that floats in this draw-in groove and with this draw-in groove inner wall between leave the clearance.

The sliding seat is composed of a convex plate and a flat plate, and the convex plate and the flat plate are locked and connected into a whole through a clamping ring.

The inner hole of the floating sliding block is oval.

The utility model discloses a structure, compare with current isolator, because the lug on shift fork and the slider that floats rotates and is connected the back, can realize the floating of certain space through the clearance between the sleeve pipe on slider that floats and the isolator body, and then at propelling movement drive gear's in-process, the slider that floats can change and then make the unsteady of adaptability according to the propelling movement position of shift fork extreme point, make the slider that floats keep the axial propelling movement of sleeve pipe all the time, just so realize the reliable stable technological effect of transmission, avoid the wearing and tearing condition of shift fork at work, make work more reliable and more stable.

The invention is further described with reference to the accompanying drawings and the detailed description.

Detailed Description

The present invention is described in detail below with reference to the following examples, which are only used for further illustration of the present invention, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1-4, the embodiment discloses an isolator with a floating slider for a starter, which comprises an isolator body 1, wherein one end of the isolator body 1 is a driving gear 11, the other end of the isolator body is a sleeve 12, one end of the driving gear 11 is matched with one end of the sleeve 12 to form a matching part 13 which has a larger outer diameter and is in a circular ring shape, the sleeve 12 is movably sleeved with the floating slider 2, the floating slider 2 is in an elliptical shape, a floating gap is reserved between an inner hole of the floating slider 2 and the outer wall of the sleeve 12, a lug 21 which is in rotating fit with a shifting fork is arranged on the outer wall of the floating slider 2, the floating slider 2 is in an elliptical shape, and the lugs 21 are symmetrically arranged on the outer walls of two sides. Therefore, the technical effect of reliable and stable transmission is achieved, the abrasion condition of the shifting fork in work is avoided, and the work is more stable and reliable.

The buffer spring 3 is disposed between the floating slider 2 and the engaging portion 13. Avoid floating slider 2 to appear touching hard state with isolator body 1 firmly in the propelling movement, the noise reduction reduces wearing and tearing, makes drive gear 11 realize the soft contact when lieing in engine flywheel gear meshing again simultaneously, avoids producing the collision between.

The cover has mobilizable baffle 4 on sleeve pipe 12, this baffle 4 sets up between buffer spring 3 and slider 2 floats, its slider 2 floats makes buffer spring 3 atress more balanced act on isolator body 1 through baffle 4, be equipped with simultaneously on slider 2 floats with 4 assorted butt grooves 22 of baffle, thereby further improve the contact surface with baffle 4, it is more inseparable to make slider 2 that floats laminate when the skew, it has spacing ring 6 still to weld connection on its tip position to be close to sleeve pipe 12, the withdrawal from sleeve pipe 12 of slider 2 that floats can be avoided to such structure.

The baffle 4 and the limit baffle ring 6 can also be replaced by a sliding seat 5, the sliding seat 5 can be movably sleeved on the sleeve 12, an annular clamping groove 50 is arranged on the outer peripheral wall of the sliding seat 5, and an inner hole of the floating sliding block 2 is sleeved in the clamping groove 50 and a gap is reserved between the inner hole and the inner wall of the clamping groove 50. The structure is simpler.

The slide carriage 5 is composed of a convex plate 51 and a flat plate 52, which are locked and connected together by a snap ring 53. This configuration makes the carriage 5 more convenient to mount.

The inner hole of the floating slide block 2 is oval. Therefore, the floating slide block 2 can perform offset sliding along the square with longer length of the inner hole, and the reliability of the structure is improved.

Adopt above-mentioned technical scheme, compare with current isolator, because the shift fork rotates with lug 21 on the slider that floats 2 and is connected the back, can realize floating of certain space through the clearance between the sleeve pipe 12 on the slider that floats 2 and the isolator body 1, and then at propelling movement drive gear 11's in-process, slider that floats 2 can change and then make the unsteady of adaptability according to the propelling movement position of shift fork extreme point, make slider that floats 2 remain the axial propelling movement of sleeve pipe 12 all the time, just so realize the reliable stable technological effect of transmission, avoid the wearing and tearing condition of shift fork in service, make work more reliable and more stable.
