Description
Technical field
The utility model relates to a kind of road roller speed change gear.
Background technique
Road roller is a kind of engineering machinery that is used for the road compacting operation.In the laying of roadway process, reach the uniform degree of compaction that job specfication requires, just need roll repeatedly new causeway road with road roller.Therefore in actual job, road roller often uses back and forth travelling that a certain fixing travelling speed frequently moves forward and backward, to realize rolling repeatedly same road surface.Therefore the switch operation of road roller is very frequent, and variable speed operation is less relatively.The speed change of road roller and commutation realize by gearbox.
The gearbox that road roller adopts in the prior art mainly contains two kinds of structural types, and a kind of is old-fashioned mechanical gear box, and is another kind of for having the gearbox of synchronizer.
Old-fashioned mechanical box mainly contains following three parts and forms: gear, changement and box of tricks.Gear is a triple axle, output shaft and the coaxial installation of input shaft.Each speed change gear is connected by spline with output shaft, and can be in the effect lower slider of reverse shift fork, and to realize different transmission speeds, the output axle head is realized exporting to the power of changement by driving bevel gear by different gear pair engagements.Changement is distributed in the driving bevel gear left and right sides and is formed with the driven bevel pinion of the normal engagement of driving bevel gear and reversing shaft, tumbler gear by a pair of.Tumbler gear is positioned in the middle of two driven bevel pinions, be connected by spline with reversing shaft, and can be under the effect of commutation shift fork move left and right, with the engagement of the internal tooth of left and right side driven bevel pinion, to realize commutation.Tumbler gear is given differential mechanism with transmission of power, and by the output of left and right sides semiaxis.
The gearbox that has synchronizer can be realized two function speed changes and commutation, and all gears all participate in speed change and commutation in the gearbox, and its commutation is to change wherein a few transmission direction to gear pair by middle idle pulley to realize.Its structure is that input shaft is coaxial installation with output shaft, and the driving gear on the input shaft is delivered to power on the jack shaft by the intermediate gear on the jack shaft, is fixedly connected with each grade driving gear and rotate with jack shaft of moving forward and backward on the jack shaft.Each grade output gear bye of advancing is enclosed within on the output shaft, and rotates with each grade driving gear engagement of advancing on the jack shaft.Retreat each grade output gear also sky be enclosed within on the output shaft, by retreating the engagement rotation of each grade driving gear on idle pulley and the jack shaft.Synchronizer is housed respectively between each output gear, and synchronizer is connected by spline with output shaft.When change speed or direction, stir a certain shift fork and make a certain synchronizer and the engagement of a certain output gear, can power on this output gear and rotation direction be delivered on the output shaft by this synchronizer.
The old-fashioned mechanical box that uses in the prior art is when speed change and commutation, owing to be the shift fork handsetting gear, make and directly mesh between tooth and the tooth, just there is the possibility of beating tooth when switching so at a high speed, therefore must earlier speed change be handled as for neutral gear when operation, power is thrown off, rotating speed descends, could carry out speed change and switch operation again, handle complicated.Owing to the unexpected variation of speed, cause the nonuniformity of road roller road pavement compacting easily simultaneously.
Though and the gearbox that has a synchronizer has solved gear engagement by synchronizer and the impact when throwing off, but, it all adopts separately independently driving gear because advancing and retreat, be subjected to the restriction of structure, it is consistent to make that the speed that moves forward and backward is difficult to, and can not satisfy the applying working condition of road roller.
Summary of the invention
The purpose of this utility model provides a kind of can the realization advancing and the switch operation that retreats under the situation that does not change the speed change gear, and manipulation is quick and steadily, alleviate the road roller gearbox of the labor intensity of driver.
The purpose of this utility model is achieved in that second is crossed main tank, odd-side, first in the clutch housing is gear shaft, order is equipped with intermediate gear and driving gear on the jack shaft in the main box body, gear on first and the intermediate gear on the jack shaft often mesh, go up synchronizer and the speed change gear that order is equipped with the connection shift fork for second that is arranged in main tank, synchronizer connects selector gear by shift fork, speed change gear on second respectively with jack shaft on driving gear often mesh, be arranged on second of odd-side forward gear and reverse-gear are housed, the commutation synchronizer is installed between forward gear and the reverse-gear second, the commutation synchronizer connects reversing gear by the commutation shift fork, reverse shaft also is housed in the odd-side, three and output shaft, duplicate gear one end on three and forward gear engagement, idle pulley engagement on the other end and the reverse shaft, idle pulley on the reverse shaft also with second on reverse-gear engagement, the output gear on the output shaft meshes with duplicate gear one end.
Second is crossed main tank, odd-side, first in the clutch housing is gear shaft, order is equipped with intermediate gear and driving gear on the jack shaft in the main box body, gear on first and the intermediate gear on the jack shaft often mesh, go up synchronizer and the speed change gear that order is equipped with the connection shift fork for second that is arranged in main tank, synchronizer connects selector gear by shift fork, speed change gear on second respectively with jack shaft on driving gear often mesh, be arranged on second of odd-side forward gear and reverse-gear are housed, the bidirectional hydraulic clutch is installed between forward gear and the reverse-gear second, reverse shaft also is housed in the odd-side, three and output shaft, duplicate gear one end on three and forward gear engagement, idle pulley engagement on the other end and the reverse shaft, idle pulley on the reverse shaft also with second on reverse-gear engagement, the output gear on the output shaft meshes with duplicate gear one end.
Main tank is realized speed changing function, and odd-side is realized commutation and power output function.Adopt cascaded structure between speed change and the changement, promptly speed change is output as the input of commutation.Its working principle is that first shaftgear is delivered to power on the jack shaft by intermediate gear, jack shaft is given each driving gear on the axle with transmission of power, each speed change gear on each driving gear is given second with transmission of power again, speed change gear dallies on second.Handle selector gear and make synchronizer and different speed change gear engagements, power is delivered on the synchronizer by speed change gear, and drives second rotation by synchronizer, thereby makes second with different speed rotation realization speed changes.When advancing, give the commutation combination apparatus with transmission of power for second, by controlling reversing gear, make commutation combination apparatus and forward gear engagement, power passes to duplicate gear, output gear by forward gear, and realizes that through output shaft power exports; When retreating, by reversing gear, make the engagement of commutation combination apparatus and reverse-gear, power passes to idle pulley, duplicate gear, output gear by reverse-gear, realizes power output through output shaft again.
For realization is advanced in full accord with astern speed, the utility model adopts and to make forward gear and reverse-gear measure-alike, the gear size of holding about duplicate gear is also identical, for avoiding structural interference, duplicate gear one end and forward gear engagement, the other end staggers with reverse-gear and is meshed with idle pulley, and idle pulley meshes with reverse-gear again simultaneously.
