Principle of the present invention is described as follows:
Power source: traditional DCT is generally applicable to compact car, the operating mechanism of double clutch generally adopts electric energy as power source, and the design designs for commercial car, in commercial car, aerodynamic force more easily obtains compared to electric energy, the aerodynamic force used is existing gas circuit on car, without the need to other energy of loss; And the electric power on automobile comes from storage battery, storage battery needs periodic maintenance, charging, and the use of micro-machine needs uninterruptable power supply (UPS), power consumption is comparatively large, cost is higher, and Electric Machine Control precision is lower, part is easy to wear, needs periodic maintenance, therefore uses electric power to need to consume more human and material resources.Therefore adopt aerodynamic force more reasonably to optimize resource distribution in commercial car DCT control system.
Manipulating cylinder: the stroke of its inner carrier of manipulating cylinder of different size is different, according to the actual requirements, chooses the first manipulating cylinder 31 and the second manipulating cylinder 41 of suitable piston stroke; The stroke of the first manipulating cylinder 31 piston is definite value, determine the displacement amount of the first power push-rod 32, because the length of the first rocking arm 34 is certain, therefore the first angle of swing handling rotating shaft 33 is fixing, the angle of swing of the first shift fork 7 is also definite value, and the stroke that the first shift fork 7 promotes inner sliding sleeve 5 motion is also a definite value; In like manner, the stroke of the second manipulating cylinder 41 piston is definite value, determine the displacement amount of the second power push-rod 42, because the length of the second Rocker arm 44 is certain, therefore the second angle of swing handling rotating shaft 43 is fixing, the angle of swing of the second shift fork 8 is also definite value, and the stroke that the second shift fork 8 promotes outer sliding sleeve 6 motion is also a definite value; Because manipulating cylinder stable performance, control accuracy are high, make the performance of whole control system more stable, prevent a part due to control accuracy low, stressed excessive, and situation about being damaged, extends part working life.
In addition, pneumatic piston rotatable engagement in one end of described first power push-rod 32 and the first manipulating cylinder 31, the other end of the first power push-rod 32 and one end of the first rocking arm 34 are hinged, and the other end of the first rocking arm 34 is fixedly connected with the first top handling rotating shaft 33; Pneumatic piston rotatable engagement in one end of described second power push-rod 42 and the second manipulating cylinder 41, the other end of the second power push-rod 42 and one end of the second Rocker arm 44 are hinged, and the other end of the second Rocker arm 44 is fixedly connected with the second top handling rotating shaft 43.Can rotate by a small margin between piston and power push-rod in above-mentioned design, when push rod promotes rocking arm, push rod can adapt to the movement in a curve track that rocking arm twists even end by translation-angle by a small margin, and design is more reasonable, is convenient to the normal rotation of rocking arm.
Handle rotating shaft: the first manipulating cylinder 31 utilizes the first manipulation rotating shaft 33 to control the motion of inner sliding sleeve 5, and the second manipulating cylinder 41 utilizes the second manipulation rotating shaft 43 to control the motion of outer sliding sleeve 6.Such design avoids the first manipulating cylinder 31 and directly controls inner sliding sleeve 5, second manipulating cylinder 41 directly controls outer sliding sleeve 6 and makes the situation that double clutch output shaft increases, save the axial arranged space of clutch, the length of double clutch output shaft is shorter, and its mechanical strength is higher, transmitting torque performance is better.
The transmittance process of power: the first rocking arm 34 converts the push and draw force of the first power push-rod 32 rotating force of the first manipulation rotating shaft 33 to, first shift fork 7 handles rotating shaft 33 synchronous rotary with first, and the first U-shaped fork 72 of the first shift fork 7 end controls advance or the retrogressing of inner sliding sleeve 5; Second Rocker arm 44 converts the push and draw force of the second power push-rod 42 rotating force of the second manipulation rotating shaft 43 to, and the second shift fork 8 handles rotating shaft 43 synchronous rotary with second, and the second U-shaped fork 82 of the second shift fork 8 end controls advance or the retrogressing of outer sliding sleeve 6.The conversion regime of such design power is ingenious, easily accurately manipulates the movement travel of inner sliding sleeve 5, outer sliding sleeve 6.
