In this embodiment, the actuator includes actuator push disk 25, actuator push disk links firmly with the transfer bar front end, the transfer bar rear end links firmly with the back stopper pressure disk, transfer bar and separation blade sliding connection.
The working principle is as follows:
initial state: the actuator is in a low pressure state, the front brake is disengaged, the rear brake is engaged, and the transmission is in second gear (direct gear). At the moment, the pushing disc of the actuator has no acting force on the coupling piece of the wedge-shaped block, the wedge-shaped block assembly is in a releasing state, the rear brake is pressed under the action of the third elastic body, and the friction plate and the coupling piece of the friction plate are in a pressing state. According to the principle of planetary gear motion dynamics, for the CR-CR structure, the front sun gear is input, the front planet carrier is output, and the braking speed ratio of the rear sun gear is smaller than that of the front gear ring, namely 2 gears in the embodiment.
When the gear is shifted down: the pushing disc of the actuator gradually moves towards the wedge-shaped block dual piece, so that the pressing disc of the rear brake gradually moves towards the supporting piece, the third elastic body is gradually compressed, the rear brake is gradually released, and the pressing state of the friction plate and the friction plate dual piece is gradually released. Meanwhile, after the wedge-shaped block carrier sheet is pushed and pressed by the wedge-shaped block dual sheet, the second elastic body is compressed, the inclined surface of the wedge-shaped block can be exposed out of the friction surface of the wedge-shaped block carrier sheet under the action of the first elastic body (but the blocking surface at the lower side of the inclined surface of the wedge-shaped block is braked and exposed), meanwhile, the wedge-shaped block carrier sheet is driven by the front gear ring to continue rotating, the dual hole of the wedge-shaped block dual sheet is driven to slide from the lower side to the higher side of the inclined surface of the wedge-shaped block, when the dual hole of the wedge-shaped block dual sheet is not opposite to the wedge-shaped block, the wedge-shaped block is pushed by the wedge-shaped block dual sheet to compress the first elastic body, so that the wedge-shaped block is 'shrunk' into the friction surface of the wedge-shaped block carrier sheet, and the front gear ring is prevented from being instantaneously braked to cause impact; and when the speed is reduced to 0 and has a reverse rotation trend, a blocking surface on the inclined high side of the wedge block is jointed with a blocking surface of the wedge block dual-pair hole, and the wedge block limits the reverse rotation of the wedge block dual-pair piece, so that the front gear ring is braked. According to the kinematic dynamics principle of the planetary gear, the sun gear input and the gear ring are braked, the planet carrier outputs, the speed ratio is greater than 2, and the speed ratio is 1 gear in the embodiment.
When the gear is shifted up: the actuator decompresses gradually, and the actuator pushes away the dish and is oppressed to keeping away from wedge dual piece direction by the third elastomer and remove for back brake pressure disk moves to the front brake direction, until pressing on the friction disc, and the third elastomer compresses tightly the back brake gradually, and friction disc dual piece are in the state of compressing tightly, make back sun gear slow down gradually and by the braking. Meanwhile, the third elastic body pushes the actuator push disc to be far away from the wedge-shaped block dual piece through the rear brake pressure disc, the pressure of the wedge-shaped block dual piece on the wedge-shaped block carrier piece is gradually reduced, the wedge-shaped block carrier piece slides towards the wedge-shaped block dual piece under the action of the second elastic body, so that the friction surface of the wedge-shaped block carrier piece exceeds the low-side blocking surface of the wedge-shaped block, when the front gear ring starts to rotate forwards from 0 rotating speed under the action of other members of the planet row, the wedge-shaped block dual piece is driven to rotate to the high side along the low side of the wedge-shaped block inclined surface, the wedge-shaped block is pushed by the wedge-shaped block dual piece and retreats into the friction surface of the wedge-shaped block carrier piece, the wedge-shaped block dual piece can rotate relative to the wedge-shaped block carrier piece, the front gear ring continues to rotate until the actuator push disc retreats to the designed limit position, and the front gear ring frame is completely in an idling state, so that the transmission shifts. Because the actuator gradually reduces the pressure, the pressure of the corresponding rear brake pressure plate acting on the friction plate is gradually increased from 0 to the designed maximum value, in the process, the friction force of the friction plate is smaller than the acting force of the rear sun gear, the friction plate is in a sliding friction state, and the front gear ring is gradually increased from 0 rotating speed to an idle state, so that the gear shifting process is smooth.
When reversing gear: the actuator pushes the wedge-shaped block dual piece to the designed limit position, correspondingly pushes the rear brake pressure plate to move to the designed limit position away from the friction piece, and the rear brake is separated. Meanwhile, the second elastic body can not be compressed any more, and the low side blocking surface of the wedge block can be exposed out of the friction surface of the carrier sheet of the wedge block under the action of the first elastic body. When the input power rotates reversely, the front gear ring has a forward rotation trend, once the front gear ring rotates forwardly, the wedge block dual sheet is driven to rotate relative to the wedge block, the wedge block is sleeved into the dual hole of the wedge block dual sheet, one blocking surface of the dual hole and the blocking surface at the lower side of the wedge block mutually, the wedge block dual sheet does not rotate relative to the wedge block carrier sheet, and therefore the front gear ring is braked, and reverse gear is achieved.
In the design, the thrust provided by the push disc is enough to separate the rear brake and retreat the wedge block, and the total force for pushing the wedge block to retreat is smaller than 200N and much smaller than the pressing braking force (generally about 5000N), so the force for controlling the two gear shifting units is equivalent to the force for controlling one traditional gear shifting unit.
Of course, a Simpson-type transmission as depicted in FIG. 2 can be formed by a simple variation of the present invention; the ravigneaux transmission as shown in fig. 3 can also be formed by simple deformation.
It will be apparent to those skilled in the art that various modifications, changes, substitutions and alterations can be made without departing from the spirit and scope of the invention as defined by the appended claims.
