The technical solution of the utility model is as follows: include motor, casing and clutch main pump, it is characterized in that: described motor is installed on the side of casing, the output shaft of this motor stretches in casing, and be connected with worm screw, worm screw is supported with casing mutually by bearing, and the fan-shaped teeth portion of worm and wheel upper end is meshed, at the middle part of described worm gear, wheel shaft is set, this wheel shaft is supported with casing mutually by bearing, the push rod that the right-hand member of described worm gear bottom and clutch main pump stretch in casing is hinged, left surface in worm gear bottom is provided with the linear guides of circular arc, the part wheel body of directive wheel is arranged in linear guides, described directive wheel is installed on the right-hand member of guide post, the left end of guide post stretches in sleeve, both are slidably matched, the left end of described sleeve is hinged with the end cap of setting in casing, pocketed springs on described sleeve, this spring is in normal compressive state, the left end of spring abuts with the first positive stop lug boss on sleeve, the right-hand member of spring abuts with the second positive stop lug boss on guide post.
Adopt above technical scheme, when the positive and negative operating of motor, output shaft can be passed through and drive worm screw synchronous rotary, while worm screw rotates, drive worm gear around its wheel shaft center clockwise or counterclockwise, worm gear drives the push rod of clutch main pump to move to the left or to the right, thus realizing the joint of clutch and separating.Owing to guide post and sleeve are slidably matched, spring is in normal compressive state, and so under the action of the spring, directive wheel can apply pressure all the time on worm gear.
When worm gear turns clockwise, directive wheel rotates in linear guides, and promote guide post together with sleeve counter-clockwise swing, spring compresses further, spring applies resistance to worm gear, and this process can guarantee that and simulates semi-linkage state when clutch engages, and both ensure that joint smooth-going, to spring energy-storage, can also prepare for quickly disconnecting of clutch simultaneously. After clutch is fully engaged, the center of directive wheel is above guide post center with the worm gear wheel line of centres, and after motor quits work, the position of worm gear is by the pretightning force restriction of the block arranged in casing and spring, good reliability.
When worm gear rotates counterclockwise, directive wheel rotates in linear guides, and promotes guide post together with sleeve clockwise oscillation, and spring is expanded, and spring provides power-assisted to worm gear, to accelerate clutch separation speed, and ensures released state. After clutch is kept completely separate, the center of directive wheel is in the lower section at guide post center Yu the worm gear wheel line of centres, and after motor quits work, the position of worm gear is by the block restriction arranged in casing.
This utility model simple in construction, compact, volume is little, lightweight, and cost is low; Adopt conventional worm worm mechanism can realize bigger speed reducing ratio, and realize separating and joint clutch by spring, push rod and directive wheel with coordinating of linear guides. Worm gear design is not self-locking, and transmission efficiency is high; Drive system structure is compact, and processing technique is ripe, and production efficiency is high. Engage and in separation process at clutch, the guide rail according to the characteristics design of compression spring, make spring that the moment of torsion of worm gear to be remained unchanged, engage better with ride comfort when separating at clutch.
Equipped with angular displacement sensor on the wheel shaft of described worm gear. Owing to the worm gear designed and angular displacement sensor rotational angle are less than 360 ��, it is possible to avoiding worm gear being remembered, the number of turns is to controlling to bring logic challenge, reliability is higher.
Described motor is brush direct current motor, so drives strategy simple, and controller and motor cost are relatively low.
In order to simplify structure, convenient location, the left end at described sleeve is provided with locating ring, and the part ring body of this locating ring is arranged in the circular arc locating slot being correspondingly arranged on end cap.
Beneficial effect: this utility model is reasonable in design, implements easily, simple in construction, compact, and volume is little, lightweight, cost is low, and transmission efficiency is high, being able to ensure that clutch engages and the ride comfort of separation process, accuracy and reliability, all applicable on various types of automobiles, versatility is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As it is shown in figure 1, the pump housing of clutch main pump 6 is installed on the right side of casing 2, the push rod of this clutch main pump 6 stretches in casing 2 to the left. Left-hand end at casing 2 installs motor 1, and motor 1 is preferably brush direct current motor, and the output shaft of this motor 1 stretches in casing 2, and coaxially connected with worm screw 3, and worm screw 3 right low left high is obliquely installed, and the two ends of worm screw 3 are supported with casing 1 phase by bearing. Equipped with angular displacement sensor on worm screw 3, this angular displacement sensor is connected with motor 1 by control circuit.
