Description
Technical field
It the utility model is related to locomotive clutch field, and in particular to high intensity intelligent multi-directional positioning sleeve.
Background technology
Clutch is arranged between engine and speed changer, is the assembly being directly associated in automotive transmission with engine
Part.The flywheel group of usual clutch and engine crankshaft is installed together, and is cut off and passes between engine and automotive transmission
The part of graduating power.Automobile from starting to during the entire process of normally travel, driver can controlled clutch as needed, be hair
Motivation and power train are temporarily separated or gradually engaged, to cut off or transmit the power that engine exports to power train.Its effect
It is to make gradually engage between engine and speed changer, so as to ensure that automobile balance is started to walk；Temporarily disconnected engine and speed changer
Between contact, in order to shift gears and reduce impact during gearshift；Centrifugation can be played when automobile emergency brake, prevents speed change
The transmission systems such as device are overloaded, so as to play certain protective effect.
Positioning sleeve rotates under driving disc spacing pressing drive in clutch, therefore, it is necessary to bear larger moment of torsion, and working environment is disliked
It is bad, belong to easily loss parts.Existing clutch positioning sleeve relies primarily on increase friction area to strengthen to power transmission
Endurance.And how in limited dimensional space, increase the efficiency and stability of its power transmission, be those skilled in the art
The technical problem of urgent need to resolve.
The one of which clutch applied in existing automobile and engineering machinery is dry friction clutch, the interior flower of positioning sleeve
Key is slidably matched with transmission input shaft, platen drive positioning sleeve contact or separate with flywheel, wherein, the internal spline of positioning sleeve and
Transmission input shaft external splines cooperatively forms spline pair, while spline pair transmits moment of torsion, positioning sleeve and transmission input shaft
Axial direction also can be movable relatively；Because transmission input shaft is outside one end of flywheel stretching positioning sleeve, therefore travelled in vehicle
After certain mileage, caused dust and the dust from the entrance of other channels etc. can be deposited in spline pair from friction material,
Cause positioning sleeve internal spline and transmission input shaft coordinate it is not smooth, prevent spline pair between relative motion, and then cause from
Clutch separation is unclear, and speed changer and power train are made a very bad impression.
Positioning sleeve is the source of transmission input, because gearbox is defeated as being directly connected with transmission input shaft
Enter axle to rotate at a high speed in vehicle to run, amount of heat can be produced therebetween, therefore the requirement being not only to positioning sleeve in intensity, it is right
Its is wear-resisting, heat-resisting, anticorrosive property requires also higher.Existing clutch industry positioning sleeve is most to be forged or is cast using medium carbon steel,
Modifier treatment after processed then general to use phosphorating treatment more；The wear-resisting, heat-resisting of positioning sleeve, anticorrosive property are poor, clutch
After long-time use, positioning sleeve abrasion, corrosion, deformation are more serious, reduce the service life of clutch, also cause vehicle
Level of comfort reduces.
Utility model content
In view of the deficiency of background technology, technical problem to be solved in the utility model is to provide dismountable damping effect
Good, achievable precision-fit, the high intensity intelligent multi-directional positioning sleeve of stable transmission.
To achieve the above object, the utility model provides following technical scheme：
High intensity intelligent multi-directional positioning sleeve, has discoid hub body, and the hub body central is provided with raised upwards
Locating ring, the locating ring inwall are provided with internal spline, it is characterised in that：Set in the hub body and in the locating ring periphery
There are some damping grooves, elongated hole is provided between the damping groove, the outer rim of the hub body is provided with some dismountable clampings
Portion, the Access Division both side ends are inwardly formed groove, and the Access Division upper surface is additionally provided with projection, the key of the internal spline
Dilatation joint is provided between groove, receiving provided with arcuation considers groove to be worth doing to the keyway of the internal spline to the extension of bottom land direction.
The damping groove is set to recessed waist-drum-shaped.
The Access Division is carried out detachably connected with the hub body by bolt.
The internal spline surface is provided with corrosion and wear layer, and the outer surface of the hub body is provided with antiseptic and rustproof layer.
The beneficial effects of the utility model are, can be after long-term use to part by setting dismountable Access Division
Changed, reduced cost, and the Access Division is simple in construction, can also reduce certain cost so in manufacturing process, improves
Productivity effect, the setting of the groove and projection of Access Division can realize the precision-fit of positioning sleeve and other parts, ensure moment of torsion
It is normal to transmit, prevent from producing jitter phenomenon when clutch from working；Elongated hole be used for match corresponding alignment pin, can also strengthen part it
Between fitness；The setting of dilatation joint, overcome conventional internal spline and easily caused error, realization are adjusted during external splines cooperation
The technique effect of size so that coordinate even closer between internal spline and external splines, transmission is more stable.
Brief description of the drawings
The utility model has drawings described below：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 A-A sectional view；
Fig. 3 is the enlarged drawing in Fig. 1 B portions.
Embodiment
As illustrated, high intensity intelligent multi-directional positioning sleeve, by precision forging, for structure through gathering, precision is high, and rigidity is good；Adopt
With structural alloy steel, part is integrally quenched to reach comprehensive mechanical performance.The present embodiment has discoid hub body 1, the hub
The center of body 1 is provided with raised locating ring 6 upwards, and the inwall of locating ring 6 is provided with internal spline 7, and internal spline 7 adds after being heat-treated
Work, high accuracy is realized, and ensure that running balance, noise are small；Locating ring 6 is used to connect transmission input shaft, internal spline 7 and speed change
The external splines of device input shaft is engaged, and some damping grooves 4, damping are provided with the hub body 1 and in the periphery of locating ring 6
Groove 4 is used to place damping spring, is rocked with mitigating caused by its work, ensures the steady transmission to positioning sleeve moment of torsion；Institute
State and elongated hole 5 is provided between damping groove 4, elongated hole 5 and the detent fit to match, realize to high intensity intelligent multi-directional positioning sleeve
Be accurately positioned, the outer rim of the hub body 1 is provided with some dismountable Access Divisions 2, the design of dismountable Access Division 2, makes
Access Division 2 is obtained after long-term use of and impaired, only need to change the part, extend high intensity intelligent multi-directional positioning sleeve uses the longevity
