Description
Technical field
The invention belongs to automobile technical field, it relates to the topworks of a kind of automatic transmission clutch.
Background technology
Automatic transmission is when realizing clutch coupling and automatically control, it is necessary to this system parts of clutch actuating mechanism, and its effect realizes automatic control clutch function. Current clutch actuating mechanism is divided into two classes by structure, a class electric-liquid type topworks, and another class is dynamo-electric formula topworks. Although electro-hydraulic pressure type topworks fast response time, being conducive to the raising of the comfortable property of whole car and cornering ability, but hydraulic pressure power loss is big, transfer efficiency is low, affects the fuel-economy type of whole car; Traditional dynamo-electric formula topworks, transfer efficiency height, power loss is little, be conducive to the fuel-economy type of whole car, but response speed is slow, is unfavorable for the raising of the comfortable property of whole car and cornering ability, and complex structure, to take space big, manufacturing cost height, is unfavorable for arrangement etc.
At present, the clutch actuating mechanism of the dynamo-electric formula of the employing of existing automatic transmission, all needs through more than two or three grade transmission, the driving moment of motor could be delivered to separation shift fork place. As disclosed in Chinese patent, one is simple and reliable, clean quietly for the separation of motor and the electric performance device [201020229385.6] of combination. It comprises: act on the separation bearing on clutch pressure plate, stirs the separation shift fork of separation bearing, the shift fork axle of fixedly separated shift fork, drives the swing connecting bar that shift fork axle rotates, and promotes the electric pushrod of swing connecting bar, for electric pushrod provides the driving circuit of electric energy.Electric pushrod is a kind of through step down gear, worm screw worm gear, nut-screw, is the mechanism of translational motion by the converting rotary motion of motor. Driving circuit contains three groups of phase converters and the motor control unit of the three-phase brushless dc motor offer electric current of promising electric pushrod. Electric pushrod is provided with the magneticinduction position transducer of its stroke of control. Its advantage is: the one-piece construction simplifying executive device, operates steadily, registration; Its shortcoming is: complex structure, takies space big, cost height, whole car difficulty in arrangement, it is necessary to through more than two or three grade transmission, the driving moment of motor could be delivered to separation shift fork place, and transfer efficiency also just decreases relatively.
Summary of the invention
It is an object of the invention to there are the problems referred to above for existing technology, it is proposed that the topworks of the automatic transmission clutch that a kind of transmission efficiency is high.
The object of the present invention realizes by following technical proposal: the topworks of a kind of automatic transmission clutch, comprise the motor being fixed on clutch coupling housing, the shift fork that is separated being hinged with clutch coupling housing is separated bearing with acting on pressure dish, it is characterized in that, it is provided with and the fulcrum that clutch coupling housing is hinged in the middle part of described separation shift fork, described motor rotating shaft is arranged with belt wheel, the wheel face of described belt wheel is wound with one end be separated shift fork be connected mutually and can drive be separated shift fork swing steel band, described separation shift fork can promote separation bearing to move after swinging.
Shift fork is connected steel band with being separated, and motor drives steel band tension separation shift fork to swing around fulcrum after running. Bearing is connected the separation lower end of shift fork with being separated, and drives release shaft to make for pressing dish, it is achieved the object that automatic control clutch combines in separation shift fork swing process. Owing to motor directly drives separation shift fork motion, simplify a series of transmission rigs, transmission efficiency is higher, power loss is little, be conducive to the fuel-economy type of whole car, fast response time, is conducive to the raising of the comfortable property of whole car and cornering ability, and structure simple, take that space is little, low cost of manufacture, the layout of whole car of being conducive to.
In the topworks of above-mentioned automatic transmission clutch, flat shape hole has been offered in described separation shift fork upper end, described steel band through flat shape hole and be separated shift fork welding be connected, the other end is connected on belt wheel. When steel band tightens up, separation shift fork is pulled to belt wheel, and the lower end of separation shift fork promotes separation bearing.
In the topworks of above-mentioned automatic transmission clutch, described steel band be separated shift fork, to be separated bearing in the same plane. Steel band motion can not cause separation shift fork deflection, is in all the time and swings in this plane.
In the topworks of above-mentioned automatic transmission clutch, described motor, separation bearing lay respectively at the both sides of separation shift fork, and described steel band is perpendicular to separation shift fork. Steel band is with to be separated shift fork vertical, more laborsaving when pulling separation shift fork, transmission efficiency height.
In the topworks of above-mentioned automatic transmission clutch, shift fork touching position point is tie point two to described steel band with being separated, shift fork touching position point is tie point one to described separation bearing with being separated, and described fulcrum, tie point one, tie point two are on same straight line. Sight alignment, separation shift fork swings more laborsaving, promotes separation bearing movable also simpler.
In the topworks of above-mentioned automatic transmission clutch, having the fulcrum of protrusion in the middle part of described separation shift fork, described fulcrum is connected with clutch coupling housing, and tie point one is 1:3～6 to the distance of fulcrum and tie point two to the ratio of distances constant of fulcrum.By lever principle, tie point two is relatively long to the distance of fulcrum so that motor more easily promotes separation shift fork to swing around fulcrum.
In the topworks of above-mentioned automatic transmission clutch, described separation shift fork is that tabular and two sides all have flange. Flange can improve the intensity of separation shift fork, prevents bending.
Compared with prior art, the topworks of this automatic transmission clutch has the following advantages:
1. structure is simple, takies space little.
2. transmission efficiency height, is directly delivered on separation shift fork by the motivating force of motor, eliminates a series of transmission rigs.
3. reduce the cost of development of topworks.
