Abstract
The utility model discloses a middle controlling-locking gear transmission mechanism, which comprises a motor, a motor shaft, a driving gear and a clutch mechanism that comprises a driven gear. The transmission mechanism is also provided with a shaft housing and a lock sleeve, wherein, the motor shaft is a D-shaped shaft, the driving gear, the shaft housing and the lock sleeve are enclosed on the motor shaft in turn, the clutch mechanism is enclosed on the shaft housing, a pad is arranged between the lock sleeve and the clutch mechanism and between the driving gear and the clutch mechanism, and the clutch mechanism is provided with a shrapnel that supports against the pad between the lock sleeve and the clutch mechanism. Since the motor shaft is a D-shaped shaft, even though the interference cooperation is not adopted between the driving gear and the motor shaft, no sliding phenomenon occurs between the driving gear and the motor shaft. In addition, the shaft housing that is arranged between the clutch mechanism and the motor shaft can protect the surface of the motor shaft from being worn down by the clutch mechanism.
Description
Technical field
The utility model relates to a kind of motor central lock, relates in particular to a kind of gear drive that is used for central controlled lock.
Background technology
Central controlled lock, promptly central locking control is the standard fitting of automobile, especially car.Central controlled lock all contains a gear drive.This gear drive mainly comprises motor, be installed in the clutch of driving gear, minipad, With a driven gear and stainless steel shell fragment on the motor drive shaft and the fixing lock washer of clutch.Driving gear need be held motor drive shaft tightly, can not produce skidding.Because motor drive shaft all is that employing is cylindrical at present, must adopt interference fit between driving gear and the motor drive shaft, just can make driving gear embrace motor drive shaft tightly.Correspondingly, the requirement on machining accuracy on the surface that driving gear and motor drive shaft are cooperatively interacted will be than higher, and cost of production will increase like this.In addition, relatively rotating also between clutch and the motor drive shaft can be caused wearing and tearing to the motor drive shaft surface.
Need to provide a kind of central controlled lock gear drive to address the above problem for this reason.
The utility model content
Based on the deficiencies in the prior art, problem to be solved in the utility model just provides a kind of central controlled lock gear drive, with the machining accuracy of fitting face between reduction driving gear and the motor drive shaft, and the wearing and tearing that can effectively alleviate motor drive shaft.
In order to address the above problem, the utility model central controlled lock gear drive has adopted following technical scheme: the clutch that it comprises motor, motor drive shaft, driving gear and contains driven gear, also comprise axle sleeve and lock sleeve, motor drive shaft is the D oblique crank Z, driving gear, axle sleeve and lock sleeve are enclosed within on the motor drive shaft successively, clutch is enclosed within on the axle sleeve, be respectively equipped with pad between lock sleeve and driving gear and the clutch, clutch is provided with shell fragment, and shell fragment props up the pad between lock sleeve and the clutch.
Because motor drive shaft is the D oblique crank Z, do not adopt interference fit even reduce between driving gear and the motor drive shaft, can not produce skidding between driving gear and the motor drive shaft yet.In addition, institute's pad axle sleeve can protect the surface of motor drive shaft not worn and torn by clutch between clutch and the motor drive shaft.
As an embodiment of the utility model central controlled lock gear drive, lock sleeve is the copper lock sleeve.The quality of copper is lighter relatively, can alleviate the weight of whole gear drive like this.
As another embodiment of the utility model central controlled lock gear drive, motor gear is the gear of powder metallurgy material.The gear of this material is not fragile.
Below in conjunction with accompanying drawing the utility model central controlled lock gear drive is described in detail.
Description of drawings
Fig. 1 is the exploded view of an embodiment of the utility model central controlled lock gear drive;
Fig. 2 is a sectional drawing embodiment illustrated in fig. 1;
Fig. 3 is the partial enlarged drawing of sectional drawing shown in Figure 2.
The specific embodiment
With reference now to accompanying drawing, preferred embodiment of the present utility model is described.
As Fig. 1, Fig. 2 and shown in Figure 3, as preferred embodiment of the utility model central controlled lock gear drive, the central controlled lock gear drive comprises motor 10, the clutch 14 of motor drive shaft 11, driving gear 12, packing ring 13 and 16, With a driven gear 42 and stainless steel shell fragment 41, axle sleeve 15 and lock sleeve 17.Motor drive shaft 11 is the D oblique crank Z, and driving gear 12 is the gear of powder metallurgy material, and lock sleeve 17 then is a copper sheathing.Driving gear 12, axle sleeve 15, packing ring 16 and lock sleeve 17 are enclosed within on the motor drive shaft 11 successively.Packing ring 13 and clutch 14 are enclosed within on the axle sleeve 15 again successively.The free end of the stainless steel shell fragment 41 on the clutch 14 props up the bottom of packing ring 16.Because packing ring 16 directly is enclosed within on the motor drive shaft 11, and is sandwiched between lock sleeve 17 and the axle sleeve 15, axle sleeve 17 just can packing washer 16 like this.16 on packing ring compresses stainless steel shell fragment 41, can give clutch 14 certain frictional force like this, and clutch 14 can be closed and throw off automatically.
Because motor drive shaft is the D oblique crank Z, driving gear 12 just can not skid on motor drive shaft 11 like this, correspondingly no longer needs than higher quality of fit between driving gear and the motor drive shaft.Axle sleeve 15 separates motor drive shaft 11 and clutch 14, the surface of the motor drive shaft 11 that just can not wear and tear when clutch 14 moves like this.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
