Description
BACKGROUND OF THE
The automatic transmission is a device in which the gear is automatically operated according to the speed at which the gear ratio is automatically selected and operated, regardless of the driver's operation. This automatic transmission automates the rudder operation and gear shifting required for the car to run.
In addition, depending on the speed set for each car and stepping on the accelerator, the appropriate gear is selected.
This automatic transmission is designed so that the gear ratio can be automatically selected by activating the fluid clutch, band or disc plate.
Typically, automatic transmissions include Ravigneaux or Simpson planetary gear units that include sun gear, planetary gears, ring gears, and planet gear carriers.
This planetary gear unit is required to have a complicated structure in which a sun gear, a planetary gear, a ring gear, and a planetary gear carrier are selectively engaged with an input shaft and an output shaft, respectively. The power of the input shaft is not instantaneously transmitted to the output shaft, and the driven object may fall freely when the driven object is receiving gravity.
Further, the conventional automatic transmission has a problem that it can provide a plurality of transmission stages, but can not provide infinitely many transmission stages.
An infinite transmission for solving such a problem is disclosed in Korean Patent No. 10-102968.
The above-described infinite transmission has a plurality of driven gears, each of which has a smaller diameter as it goes to one side, circumscribes the input shaft via a one-way clutch, and a plurality of driven gears, which are meshed with these driving gears, And a plurality of contact pressing members which are in contact with the inner circumferential surface of the plurality of driven gears by centrifugal force are mounted on the output shaft so as to be movable in the radial direction of the plurality of contact pressing members, And a loader of a support unit which is reciprocated by a translating portion in the output shaft so as to selectively support the contact pressing member so that power can be transmitted from the input shaft to the output shaft while being transmitted without loss of power transmission.
However, in the above-described automatic transmission, only when the plurality of contact pressure members are radially outwardly opened by the centrifugal force, the loader of the support unit enters between the two contact pressure members of the plurality of contact pressure members, So that the two contact pressing members contact and press the two driven gears among the plurality of driven gears to transmit the power transmitted from the driving gear to the two driven gears to be transmitted to the output shaft However, in a state in which the centrifugal force is not generated in the plurality of contact pressure members because the output shaft is not rotated, for example, in a state where the loader of the support unit is in the neutral position or the input shaft is stopped, A plurality of contact pressure members disposed above the contact pressure members are arranged in a radial direction So that the driven gears can not rotate and the power of the input shaft can not be transmitted to the output shaft even if the input shaft is restarted. Furthermore, since the left-right movement of the loader of the support unit is caused by gravity, The input shaft is driven to drive the driven shaft in order to constantly apply the centrifugal force to the plurality of contact pressure members because the shifting member can not enter between the contact pressing members which are obstructed by the pressure members, There is a problem in that it is impossible to realize a neutral state and there is a problem that a plurality of recesses are formed on the inner circumferential surface of the driven gear to cause a collision between the contact pressing member and the recessed portion due to the centrifugal force and noise is generated.
An automatic transmission for solving the above problem is disclosed in Patent Registration No. 10-0042099, which is patented and patent registered by the present inventor.
The above-described automatic transmission includes bolt and nut means fixedly inscribed on a tubular shaft; A chain base portion which is fastened to the bolt and nut means and slidably inserted in the tubular shaft; And a plurality of recesses are formed on the inner circumferential surface of the inner race of the one-way clutch at predetermined intervals along the circumferential direction of the one raceway clutch And a plurality of spur gears having a larger diameter toward an axial side; When the radially inner portion is seated in a plurality of through holes formed at predetermined intervals in the axial direction at the portions of the tubular shafts facing the plurality of spur gears and selectively pressed by the chain base portion in the radial outward direction to be pressed, And a plurality of spur gears fixedly circumscribed to the output shaft and meshing with the plurality of spur gears and having a smaller diameter toward the one axial side in the axial direction, And an automatic transmission having a length capable of contacting at least two protruding and retracting members including an driven gear portion and an axial length of the chain base portion in the axial direction.
In the above-described automatic transmission, when the chain base portion simultaneously engages two drive gears having different diameters, the two gears rotate equally by the tubular shaft, and the two driven gears, which are engaged with the two drive gears, The rotational force of the two driving gears having different circumferential speeds is applied to the gear, and the driven shaft fixedly inscribed on the two driven gears fixedly circumscribed to the driven shaft is subjected to the rotational forces of the peripheral speed, However, since the driving gears are rotatably circumscribed by the one-way clutch on the tubular shaft, only the driving gear of the larger diameter among the two driving gears is larger than the larger one of the two driven gears And transmits a rotational force to a small driven gear engaged with the drive gear, and a large driven gear of two driven gears fixedly circumscribed to the driven shaft The small drive gear is rotated in the same direction as the rotational direction of the tubular shaft by the peripheral speed of the tubular shaft, so that any p / drive gear, tubular shaft, and driven shaft are not damaged.
However, in the above-described automatic transmission, the driving force is transmitted to the driven shaft selectively by one of the plurality of driving gears by the engaging clutch in a state in which a plurality of driving gears are actually circumscribed via the bearings and the one- However, since a plurality of driven gears are fixedly circumscribed on the driven shaft, not only the driven gear engaged with the one drive gear among the plurality of driven gears rotates but also all of the driven gears rotate together with the driven shaft, There is a problem that a large power is required to transmit the driving force to the coaxial shaft.
An infinite transmission for solving such a problem has been proposed in the pending patent application No. 10-2013-0108100 filed by the present inventor.
In the proposed infinitely variable transmission, both the drive gear and the driven gear are arranged in parallel with each other, and the driven shaft and the driven gear are interposed with each other through a bearing in the drive gear group, Way clutch is interposed between the drive shaft and the drive gear group or between the driven shaft and the driven gear group and the driven shaft of the driven and driven clutches of the driven and driven clutches using the bolt and nut means on the drive shaft and the driven shaft, And the driven chain base unit move synchronously in the axial direction to selectively engage the two drive gears of the plurality of drive gears and the two driven gears meshed with the two drive gears, As shown in Fig.
In the proposed infinite transmission, there has been proposed a mode switching means for moving the drive wheel base portion and the driven wheel base portion synchronously and at the same speed in the axial direction by their own power sources. However, the rotational speed of the input shaft is unchanged Since the rotational speed of the output shaft is variable, the gear ratio for matching the relative speed between the input shaft and the input shaft nut and the relative speed between the output shaft and the output shaft nut is too limited, ≪ / RTI >
An infinite transmission for solving such a problem has been proposed in the pending patent application No. 10-2013-0110910 filed by the present inventor.
In the proposed infinite transmission, the drive gear and the driven gear are arranged in parallel with each other, and the drive shaft and the driven gear are internally connected to each other through the bearing, Way clutch is interposed between the drive shaft and the drive gear group or between the driven shaft and the driven gear group and the driven shaft of the driven and driven clutches of the driven and driven clutches using the bolt and nut means on the drive shaft and the driven shaft, And the driven chain base portion is moved in the axial direction synchronously by the mode switching means driven by the power source of the infinite transmission, so that any two of the plurality of driving gears and two of the driving gears engaged with the two driving gears The mode switching means transmits the driving force of the drive shaft to the driven shaft by engaging the driven gear, A relative speed difference generator for rotating the output screw shaft in forward and reverse directions at a speed faster or slower than the rotational speed of the output shaft, And a relative speed difference transmitting portion for transmitting the rotational speed of the output shaft to the input screw shaft by a relative speed difference between the output worm nuts. Even when the driving force is transmitted to the driven shaft through the driven gear by one of the plurality of driving gears, Only the driven gear engaged with the one drive gear among the plurality of driven gears circumscribed to the driven shaft transmits the driving force to the driven shaft and the other driven gears are idle or held in position, To the driven shaft without giving a load in the rotating direction by the driving shaft Mode switching means for shifting the drive wobble base portion and the driven wobble base portion synchronously and at the same speed in the axial direction by their own power source can freely adjust the gear ratio while reducing manufacturing cost and maintenance cost, , Thereby increasing the diversity for industrial application.
However, in the above-described infinite transmission, the input shaft and the output shaft are still in the form of a tubular shaft, a plurality of through holes are formed in the tubular shaft on which the protruding and retreating members are seated, A large impact force is generated on the input shaft and the output shaft, and the input shaft and the output shaft are deformed globally or the plurality of through holes are deformed, so that the engaged small gear is not operated properly .
The present invention has a problem in solving the above-mentioned problems.
The present invention is characterized in that both the drive gear group and the driven gear group are disposed in parallel to each other and both the drive shaft rotatably inscribed in the drive gear group and the driven shaft rotatably inscribed in the driven gear group are engaged with each other, Wherein a guide slot groove extending in the axial direction is formed on the outer peripheral surface of the driven shaft and the outer peripheral surface of the driven shaft so that a one-way clutch is interposed between the drive shaft and the driven gear group or between the driven shaft and the driven gear group, The drive chain portion and the driven chain base portion of the p / drive clutches using the bolt and nut means mounted on the coaxial guide slot groove are synchronously moved in the axial direction by the mode switching means driven by the power source of the infinite transmission And selectively moves one of two adjacent driving gears out of the plurality of driving gears and one of the two driving gears The mode switching means transmits the driving force of the driving shaft to the driven shaft by engaging the driven gear engaged with the driven gear and the other driven gear adjacent to the driven gear, The first input sun gear engaged with the first input planet gear is rotated in the same manner as the revolution direction and revolution speed of the circumscribed first input planetary gear so that the magnetic force from the first input sun gear is transmitted to the first input planet gear An input tuning unit for selectively receiving the driving force of the output shaft in a state in which the first input sun gear is not transmitted, an idling direction of the first output planetary gear fixedly circumscribed to the output screw shaft, The first output sun gear meshed with the first output planetary gear is rotated so that a magnetic force from the first output sun gear is transmitted to the first output planetary gear An output tuning unit for selectively receiving the driving force of the output shaft in a state in which the first output sun gear is not transmitted to the output tuning unit and the driving force of the output shaft to the output tuning unit to rotate the output nut in the forward and reverse directions of the output screw shaft, And an input nut positioning unit that transmits the driving force of the output shaft to the input tuning unit and rotates the input screw shaft in the forward and reverse directions by the number of revolutions of the output screw shaft to move the input nut in the axial direction , The above problems can be solved.
According to the present invention, even when a driving force is transmitted to a driven shaft through a driven gear by a driving gear of a plurality of driving gears, Only the driven gear engaged with the driving gear of the other driven gear is transmitted to the driven shaft and the other driven gears are idle or held in position to give a load in the rotating direction by the weight of the other driven gear to the driven shaft Mode shifting means for shifting the drive chain base portion and the driven chain base portion synchronously and at the same speed in the axial direction by their own power source enables the gear ratio to be transmitted to the driven shaft with a small driving force, The input shaft which is the drive shaft and the output shaft which is the driven shaft serve as the solid shaft, Even if an impact force is generated on the driven shaft due to momentary coupling of the driven shaft and the driven gear, and the drive shaft and the drive gear are momentarily coupled, even if an impact force is generated on the drive shaft, durability have.
