Abstract
An AMT (automated mechanical transmission) clutch mechanism for a commercial vehicle relates to the technical field of automobile transmission AMT control. The AMT clutch mechanism for the commercial vehicle comprises a transmission case and a clutch mechanism; the AMT clutch mechanism comprises a clutch motor, a clutch worm (1), a clutch worm gear (2) and a booster spring (3); the clutch motor is arranged on the transmission case; the clutch worm (1) is in drive connection with a power output shaft of the clutch motor; the clutch worm gear (2) is movably arranged on the transmission case through a rotating shaft; the clutch worm gear (2) is in drive connection with a clutch lever of the clutch mechanism, and the clutch worm gear (2) meshes with the clutch worm (1). The problem the motor is subjected to a relatively high disengaging force of a diaphragm spring when a clutch disengages is effectively solved by the AMT clutch mechanism disclosed by the invention, so that work efficiency of the motor is increased; by utilizing self-locking property of worm gear and worm drive, the clutch can be kept at a current position when engaging, therefore a difficulty in control when the clutch engages is effectively solved, and starting impact caused by excessive engaging cannot occur.
Description
Technical field
The present invention relates to automobile gearbox AMT control technique field, be specifically related to a kind of commercial car AMT clutch mechanism.
Background technique
Clutch Control controls to be a difficult point to automobile gearbox AMT, and when namely requiring to be separated, strength is enough large and quick, can be just fast soon when requiring again to engage, can be just slow slowly, but also can not engage excessive, impacts to prevent starting.When clutch is separated, the Separating force of diaphragm spring is very large concerning motor, and clutch mechanism should overcome huge Separating force, again quick separating, such requirement, only it is not all right for increasing speed ratio, even if speed ratio is large to a certain extent, clutch can be separated, but the platen of clutch is a spring, more depress Separating force is larger, and like this working efficiency section of motor is not just in optimum efficiency section, is in other words that efficiency is not high.
Summary of the invention
Object of the present invention mainly in order to solve the problems of the technologies described above, and provides a kind of commercial car AMT clutch mechanism.
The present invention includes gear box and clutch mechanism, described AMT clutch mechanism comprises clutch motor, clutch worm screw, clutch worm gear and power assistant spring, described clutch motor is arranged on gear box, described clutch worm screw is connected with the pto of clutch motor, described clutch worm gear is movably arranged on gear box by rotating shaft, clutch worm gear is connected with the trip(ping) lever transmission of clutch mechanism, and clutch worm gear is meshed with clutch worm screw, one end of described power assistant spring is fixedly mounted on gear box, the other end of power assistant spring is connected on clutch worm gear.
Described clutch worm gear is also provided with spring coupling plate, and described power assistant spring is connected on spring coupling plate.
When two end points sight alignments of the central point of clutch worm gear and power assistant spring, power assistant spring is compressed into the shortest.
The angle of lead of described clutch worm screw is less than 3 ° 29 ' 11 ".
Advantage of the present invention is: the present invention effectively solves clutch when being separated, and the problem that the Separating force of diaphragm spring is larger to motor, improves the working efficiency of motor; Utilizing the self-locking performance of Worm Wheel System, making clutch can keep current location when engaging, effectively solve the difficult point controlled when engaging, can not engage and excessively cause starting to be impacted.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, clutch worm screw; 2, clutch worm gear; 2-1, spring coupling plate; 3, power assistant spring.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the present invention includes gear box and clutch mechanism, described AMT clutch mechanism comprises clutch motor, clutch worm screw 1, clutch worm gear 2 and power assistant spring 3, described clutch motor is arranged on gear box, described clutch worm screw 1 is connected with the pto of clutch motor, described clutch worm gear 2 is movably arranged on gear box by rotating shaft, clutch worm gear 2 is connected with the trip(ping) lever transmission of clutch mechanism, and clutch worm gear 2 is meshed with clutch worm screw 1, one end of described power assistant spring 3 is fixedly mounted on gear box, the other end of power assistant spring 3 is connected on clutch worm gear 2.
Described clutch worm gear 2 is also provided with spring coupling plate 2-1, and described power assistant spring 3 is connected on spring coupling plate 2-1.
When two end points sight alignments of the central point of clutch worm gear 2 and power assistant spring 3, power assistant spring 3 is compressed into the shortest.
The angle of lead of described clutch worm screw 1 is less than 3 ° 29 ' 11 ".
Working method and principle: when the central point o point of clutch worm gear 2 and two end points a points of power assistant spring 3 and b point sight alignment, power assistant spring 3 is compressed into the shortest, power assistant spring 3 is maximum by compression, now spring force is maximum, but be 0 for the arm of force of clutch worm gear 2 center o point, therefore the power-assisted of power assistant spring 3 distance is 0, when clutch worm screw 1 drives clutch worm gear 2 to rotate clockwise, the arm of force increases gradually, therefore the power-assisted of power assistant spring 3 is apart from also increasing gradually, now the thrust of the platen of clutch mechanism also progressively strengthens, just in time push clutch mechanism platen open at help motor, clutch in conjunction with time, the powerful thrust of platen overcomes the moment of power assistant spring 3, add clutch motor reversion, power assistant spring 3 is pushed back original initial position again.At initial position because the arm of force of spring is 0, moment is 0, so on clutch motor without any impact.
Clutch in conjunction with time, the ability of diaphragm spring is stored in power assistant spring 3, so as clutch be separated time power-assisted.
Simultaneously due to the self-locking performance of Worm Wheel System, as long as clutch motor when being separated and engage does not work all can keep current location.
