Below in conjunction with embodiment, the utility model is described in further detail.
See Fig. 1, the utility model comprises five grades of single countershaft transmissions and power take-off, five grades of single countershaft transmissions comprise housing and are arranged on the axle in housing, two axles and countershaft assembly 9, one axle and its rear end gear are set to integrative-structure, the front end of two axles is bearing in a shaft rear end bearing hole through bearing, countershaft assembly 9 is arranged on the one-sided of two axles, two axles connect speed changer flange plate 8, one shaft rear end is provided with constant mesh gear, two axles are disposed with the fourth gear 1 of empty set on two axles, three-range transmission 2, intermediate gear 3, one grade of gear 4, reverse gear 5 and overdirve gear gear 6, reverse gear 5 on two axles adopts straight-tooth sliding gear collar to shift gears, all the other each shelves gears adopt synchronizer gearshift, each shelves gear on two axles and adjacent synchronizer in conjunction with gear ring by spline engagement or be welded as a whole.The tooth hub of synchronizer and two axles by spline joint, when sliding sleeve moves with shift fork, the combining in conjunction with tooth in conjunction with tooth and synchronizer of sliding sleeve.Countershaft assembly 9 comprises jack shaft, jack shaft is provided with the driving gear engaged with the constant mesh gear of an axle, and the shifting gear of to answer with each shelves gear mesh on two axles, shifting gear on jack shaft often engages with shelves gear each on two axles, and the jack shaft shifting gear corresponding with two axle reverse gears 5 engages with reverse idler gear;
See Fig. 2, housing comprises the front case 17 and rear case 10 that match, front case 17 offers the window of two installation power take-offs, and two windows be positioned at medium axle diameter to both sides, power take-off can be arranged on arbitrary window or two windows, window on front case 17, when not installing power take-off, window arranges cover plate shutoff window.Power take-off comprises driving shaft and driven shaft, and the driving gear 16 be arranged on driving shaft, the jack shaft shifting gear that driving gear 16 is corresponding with three-range transmission 2 engages, driving shaft is also provided with driving gear 15, driving gear 15 is driven by driving gear 16, driven shaft is provided with driven gear 14, driven gear 14 is driven by driving gear 15, driven shaft connects power take-off flange plate 13 outputting power, the sense of rotation of power take-off flange plate 13 is contrary with an axle sense of rotation, driving gear (15) is controlled by cylinder (12), in needs power take-off working room, after the power take-off pore connection 0.7Mpa air pressure of cylinder (12), air pressure acts directly on piston, and promote driving gear to left movement, driving gear moves certain distance and engages transmitting torque with driving gear.
Speed changer is five grades of single countershaft transmissions, two axles is provided with successively into fourth gear 1, three-range transmission 2, intermediate gear 3, one grade of gear 4, reverse gear 5 and overdirve gear gear 6.Speed changer one shaft rear end and constant mesh gear are made of one, and two axle front ends are bearing in a shaft rear end hole through bearing.One shaftgear drives jack shaft driving gear, and on jack shaft, each shelves gear often engages with shelves gear each on two axles, and except reverse gear is with except the gearshift of straight-tooth sliding gear collar, all the other each shelves are synchronizer gearshift.Power take-off from the power taking of transmission countershaft three-range transmission, and from speed changer output flange to an axle direction, can be arranged on left side or the right side of speed changer front case 17.
The utility model assembly working procedure: as shown in Figure 1, the power of motor passes to a shaftgear of speed changer by clutch, one shaftgear often engages with jack shaft driving gear, driving jack shaft rotates, other shifting gear of jack shaft often engages with each shifting gear of two axles respectively, each gear empty set on two axles on two axles and with adjacent synchronizer in conjunction with gear ring by spline engagement or be welded as a whole.Because synchromesh gear hub and two axles are by splined, when sliding sleeve moves with shift fork, combining in conjunction with tooth with synchronizer in conjunction with tooth of sliding sleeve, two axles just become to be integrated with two shaftgears and rotate and transferring power by certain speed ratio.
During coupling power take-off, power passes through the meshing relation of a shaftgear and jack shaft driving gear after an axle input, driving jack shaft rotates, and third-speed gear of intermediate shaft is connected synchronous rotary with jack shaft because of interference, and then the power take-off driving gear be engaged with also rotates thereupon.
During power take-off inoperative, vent stuffiness, driven gear leans on to the right.Power inputs from an axle, successively through a shaftgear, jack shaft driving gear and third-speed gear of intermediate shaft, finally arrives power take-off driving gear;
During power take-off work, vent is ventilated, and driven gear leans on left.Power inputs from an axle, successively through a shaftgear, jack shaft driving gear, third-speed gear of intermediate shaft, power take-off driving gear, driving gear and driven gear, finally arrives power take-off flange plate.
From speed changer output flange to an axle direction, speed changer front case 17 arranged on left and right sides leaves two power taking windows respectively, can install two power take-offs simultaneously, also can install left power take-off or right power take-off respectively, left and right power take-off flange plate rotation direction is contrary with an axle.
The utility model is followed successively by fourth gear, third gear, second gear, one grade, reverse gear and overdirve gear, and speed changer one shaft rear end and its rear end gear are set as integrative-structure, and two axle front ends are bearing in a shaft rear end hole through bearing.One shaftgear drives jack shaft driving gear, and on jack shaft, each shelves gear often engages with shelves gear each on two axles, and except reverse gear is with except the gearshift of straight-tooth sliding gear collar, all the other each shelves are synchronizer gearshift.Due to this structural feature, power take-off must design from third-speed gear of intermediate shaft power taking.
Power take-off driving gear often engages with third-speed gear of intermediate shaft, and when power take-off vent is without air pressure, power take-off off working state, driving gear is close to the right side and leans on, and power take-off is in neutral gear position.When power take-off vent has air pressure to input, power take-off working state, driving gear leans on left, and driving gear engages by end-tooth with driving gear, and driving gear rotates together with driving gear, and drives driven gear and flange plate work.
From speed changer output flange to an axle direction, power take-off can be arranged on the right side of speed changer, also can be arranged on the left of speed changer.If be arranged on the right side of speed changer, can by the shutoff of left side power taking window cover plate, vice versa.On the left of being arranged in or right side is same power take-off, and just it have rotated certain angle around jack shaft, and when speed changer assembles left and right two power take-off simultaneously, left and right power take-off can work simultaneously.
