Abstract
The invention provides an actuator of an automatic transmission clutch and belongs to the technical field of automobiles. The problem that an actuator of an existing clutch needs transmission of more than two to three levels to transmit driving torque of a motor to a separating shifting fork, and correspondingly transmission efficiency is lowered is solved. The actuator of the automatic transmission clutch comprises a motor fixed on a clutch shell body, a separating shifting fork hinged to the clutch shell body, and a separating bearing which has an effect on a pressing disc. A belt wheel is arranged on a motor rotating shaft in a sleeved mode. A steel belt winds the wheel face of the belt wheel, one end of the steel belt is fixedly connected with the separating shifting fork, and the steel belt can drive the separating shifting fork to swing. After the separating shifting fork swings, the separating bearing can be pushed to move. The motor directly drives the separating shifting fork to move through the steel belt, a series of transmission mechanisms are simplified, so that structure is simplified, and transmission efficiency is higher.
Description
Technical field
The invention belongs to automobile technical field, relate to a kind of actuator of automatic transmission clutch.
Background technique
Automatic transmission, when realizing clutch and automatically control, needs this system parts of clutch actuating mechanism, and its effect is to realize automatic control clutch function.Clutch actuating mechanism is divided into two Lei，Yi Lei electrolyte type actuators by structure at present, and another kind of is electromechanical actuator.Although electricity hydraulic type actuator fast response time, is conducive to the raising of car load travelling comfort and cornering ability, hydraulic energy loss is large, and transmission efficiency is low, affects the fuel-economy type of car load; Traditional electromechanical actuator, transmission efficiency is high, and energy loss is little, the fuel-economy type that is conducive to car load, but speed of response is slow, be unfavorable for the raising of car load travelling comfort and cornering ability, and complex structure, take up room large, manufacture cost is high, be unfavorable for arrangement etc.
At present, the clutch actuating mechanism of the employing electromechanical of existing automatic transmission, all needs, through two or three grade of above transmission, the driving moment of motor to be delivered to disengaging yoke place.As disclosed in Chinese patent a kind of simple and reliable, the electric performance device [201020229385.6] of clean quiet separation and combination for motor.It comprises: acts on the release bearing on clutch compressing disc, stirs the disengaging yoke of release bearing, and the declutch shift shaft of fixedly separated shift fork, the swing connecting bar that drives declutch shift shaft to rotate, promotes the electric pushrod of swing connecting bar, for electric pushrod provides the drive circuit of electric energy.Electric pushrod is a kind of through reduction gear, worm and worm gear, nut-screw, changes rotatablely moving of motor into straight-line mechanism.Drive circuit provides three groups of phase changers and the motor control unit of electric current containing the three-phase brushless dc motor of promising electric pushrod.On electric pushrod, be provided with the magnetic induction position transducer of controlling its stroke.Its advantage is: simplified the overall structure of actuating device, operated steadily, registration; Its shortcoming is: complex structure, take up room large, and cost cost is high, and car load difficulty in arrangement need to could be delivered to disengaging yoke place the driving moment of motor through two or three grade of above transmission, and relatively transmission efficiency also just decreases.
Summary of the invention
The object of the invention is to have the problems referred to above for existing technology, proposed the actuator of the automatic transmission clutch that a kind of transmission efficiency is high.
Object of the present invention can realize by following technical proposal: a kind of actuator of automatic transmission clutch, comprise the motor being fixed on clutch housing, the disengaging yoke being hinged with clutch housing and act on the release bearing on platen, it is characterized in that, described disengaging yoke middle part is provided with the fulcrum being hinged with clutch housing, on described machine shaft, be arranged with belt wheel, on the wheel face of described belt wheel, be wound with the steel band that one end is connected mutually and can drives disengaging yoke to swing with disengaging yoke, described disengaging yoke can promote release bearing after swinging and move.
Steel band is connected with disengaging yoke, drives steel band tension disengaging yoke around a spot wobble after motor operation.Disengaging yoke lower end is connected with release bearing, in disengaging yoke swing process, drives release bearing to act on platen, realizes the object of automatic control clutch combination.Due to the moving disengaging yoke motion of motor straight tape splicing, simplified a series of driving mechanism, transmission efficiency is higher, energy loss is little, the fuel-economy type that is conducive to car load, fast response time, is conducive to the raising of car load travelling comfort and cornering ability, and simple in structure, little, the low cost of manufacture of taking up room, is conducive to the layout of car load.
In the actuator of above-mentioned automatic transmission clutch, described disengaging yoke upper end offers flat hole, and described steel band is connected through flat hole and with disengaging yoke welding, and the other end is connected on belt wheel.When steel band tightens up, disengaging yoke is pulled to belt wheel, and disengaging yoke lower end promotes release bearing.
In the actuator of above-mentioned automatic transmission clutch, described steel band and disengaging yoke, release bearing are in the same plane.Steel band motion can not cause disengaging yoke deflection, is in all the time and swings in this plane.
In the actuator of above-mentioned automatic transmission clutch, described motor, release bearing lay respectively at the both sides of disengaging yoke, and described steel band is perpendicular to disengaging yoke.Steel band is vertical with disengaging yoke, and more laborsaving while pulling disengaging yoke, transmission efficiency is high.
In the actuator of above-mentioned automatic transmission clutch, described steel band and disengaging yoke touching position point are tie point two, described release bearing and disengaging yoke touching position point are tie point one, and described fulcrum, tie point one, tie point two are on same straight line.Sight alignment, disengaging yoke swings more laborsaving, promotes release bearing motion also simpler.
In the actuator of above-mentioned automatic transmission clutch, described disengaging yoke middle part has the fulcrum of protrusion, and described fulcrum is connected with clutch housing, and the ratio of distances constant of tie point one to the distance of fulcrum and tie point two to fulcrum is 1:3～6.By lever principle, tie point two is relatively long to the distance of fulcrum, makes motor more easily promote disengaging yoke around a spot wobble.
In the actuator of above-mentioned automatic transmission clutch, described disengaging yoke is tabular and bi-side and all has flange.Flange can improve the intensity of disengaging yoke, prevents bending.
Compared with prior art, the actuator of this automatic transmission clutch has the following advantages:
1. simple in structure, take up room little.
2. transmission efficiency is high, by the driving force of motor, is directly delivered on disengaging yoke, has saved a series of driving mechanism.
3. reduced the development cost of actuator.
