The device is arranged on a gear box outer cover (1) and comprises a clutch actuator (2) and a clutch separation arm (4); wherein, the clutch actuator (2) is connected with the clutch separation arm (4) through a clutch stay guy (3), and the direction of the clutch stay guy (3) is in tangency with the rotation direction of the clutch separation arm (4). The utility model adopts the technical proposal to separately realize the separation and combination of the clutch; thereby having the advantages of that the process of separation is reliable, the accuracy of the monitoring is improved, ensuring the requirements of quick separation and slow combination for the clutch in the gear shifting process.
Description
Technical field
The utility model relates to speed control system of car, and more particularly, the utility model relates to a kind of clutch actuating mechanism of automobile electric control mechanical type automatic speed variator.
Background technique
At present, various types of electric control mechanical speed changer Clutch Control adopt Electric Machine Control and hydraulic control.The Electric Machine Control mode is: adopt motor---screw-nut structure, promptly motor is connected with leading screw, rotates by the motor driving leading screw, and the rotation of screw mandrel is the to-and-fro motion of drive nut again, realizes separation, the combination of clutch.Hydraulic control mode is: adopt the to-and-fro motion of hydraulic cylinder piston, drivening rod mechanism realizes separation, the combination of clutch.In above-mentioned control mode, all adopted the complicated mechanical driving mechanism between driving mechanism and the clutch structure, make the precision of transmission and reliability be affected, and be difficult for realizing the switching of manual clutch and mechanical clutch.The specification of China Patent No. CN95118464.4 discloses a kind of technology of electronic automatic speed-changing actuator for automobile, though present technique known is improved to some extent, but still fail to overcome fully above-mentioned defective.
The model utility content
Problem to be solved in the utility model provides a kind of clutch actuating mechanism of automatic gearbox, its objective is the separation of the clutch that improves automobile electric control mechanical type automatic speed variator, the control accuracy and the reliability of combination.
To achieve these goals, the technological scheme that the utility model is taked is: the clutch actuating mechanism of this automatic gearbox that is provided, be arranged on the gear box casing, comprise clutch actuator, clutch separation arm, described clutch is carried out between final controlling element and the clutch separation arm, connected by clutch cable, the sense of rotation of the direction of clutch cable and clutch separation arm is tangent.
Described clutch actuator is hydraulicdriven final controlling element hydraulic jack, and described clutch cable is connected with the piston rod of final controlling element hydraulic jack, and the moving direction of piston rod is identical with clutch cable.
The end that described clutch cable is connected with the clutch separation arm is established the backguy bulb, and clutch cable and backguy bulb are fastenedly connected, and backguy bulb and clutch separation arm junction plane are the engaged spherical to the spheroidal of clutch separation arm depression.
Described clutch actuator is provided with clutch position sensor at an end opposite with the clutch cable connecting end.
The utility model adopts technique scheme, the separation that can realize clutch separately with combine, separation process simultaneously is reliable, can monitor, precision is improved, and has guaranteed in gearshift procedure, to the quick separation of clutch, the slowly requirement of combination.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is expressed backguy bulb of Fig. 1 and clutch separation arm annexation schematic representation.
Number in the figure is: 1, gear box casing, 2, clutch actuator, 3, clutch cable, 4, the clutch separation arm, 5, clutch position sensor, 6, the separating arm rotating shaft, 7, the backguy bulb, 8, separating arm concave spherical surface, 9, the final controlling element hydraulic jack, 10, the protruding sphere of backguy bulb.
Embodiment
As Fig. 1 and the expressed structure of the present utility model of Fig. 2, the utility model is a kind of clutch actuating mechanism of automatic gearbox, be arranged on the gear box casing 1, comprise clutch actuator 2, clutch separation arm 4, be fixed on the gear box casing 1 by connecting support.Simultaneously clutch actuator 2 position of putting must guarantee that clutch finds that deflection angle can not be too big in the process of motion, in order to avoid influence the testing precision of clutch position sensor.
The main inventive concept of the utility model is to adopt backguy as motion and transferring structure power, and will guarantee the accuracy of transmission of movement, and for this reason, technical solution adopted in the utility model is as follows:
Carry out between final controlling element 2 and the clutch separation arm 4 at clutch, connected by clutch cable 3, the sense of rotation of the direction of clutch cable 3 and clutch separation arm 4 is tangent.
Concrete structure of the present utility model can be in the following way:
The end that clutch cable 3 is connected with clutch separation arm 4 is established backguy bulb 7, and clutch cable 3 is fastenedly connected with backguy bulb 2, and backguy bulb 2 and clutch separation arm 4 junction planes are the engaged spherical to the spheroidal of clutch separation arm 4 depressions.The protruding sphere 10 of backguy bulb on the backguy bulb 7 cooperates with separating arm concave spherical surface 8 on the clutch separation arm 4, guarantees the centre of sphere that clutch cable is a separating arm concave spherical surface 8 by the protruding sphere 10 of backguy bulb all the time.Clutch separation arm 4 is connected by spline with disengaging yoke.
The side-to-side movement of the piston by the final controlling element hydraulic jack 9 on the clutch actuator 2 drives clutch cable 3 motions, clutch cable 3 drives clutch separation arm 4 and rotates around separating arm rotating shaft 6, the rotation of separating arm rotating shaft 6 drives disengaging yoke and presses clutch release bearing, thus the separation that realizes clutch with combine.
Adopt the technical solution of the utility model and above-mentioned embodiment, make separation that the utility model can realize clutch separately with combine, separation process simultaneously is reliable, can monitor, precision is improved, guaranteed in gearshift procedure, to the quick separation of clutch, the slowly requirement of combination.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
