Description
Technical field
The utility model relates to the gear system technical field, is specifically related to a kind of agriculture truck change speed gear box.
Background technology
At present, the agriculture truck change speed gear box commonly used such as the patent No. are 96227140 three-wheeled farm transport vehicle change speed gear box, it comprises four transmission shafts, 12 gears, three groups of shifting fork assemblies are finished four D Drives and a reverse gear, also having its patent name of a kind of structure is five gear three-wheeled farm transport vehicle change speed gear boxs, on I axle, cliding gear is installed as power input shaft, three, fourth gear cliding gear and dual gear, this structure, gear is more, gear is few, the cost height, and many as gear is installed on the I axle of power input shaft, damage easily, complex structure, unreasonable, make change speed gear box short service life, and the reversing speed of a motor vehicle is too high, has potential safety hazard.
Summary of the invention
The purpose of this utility model just provides a kind of simple in structure, and gear distributes rationally, and the change speed gear box long service life reduces the reversing speed of a motor vehicle, improve the reversing safety the agriculture truck change speed gear box.
To achieve these goals, the technical solution of the utility model is: comprise casing, be installed in I axle, II axle, III axle, IV axle on the casing by bearings, be installed on the shifting fork assembly on the casing, and be installed in the interior differential assembly of casing, and be equipped with on the differential assembly and pass big gear wheel eventually, on the I axle as power input shaft power-transfer clutch is installed, its constructional feature is: I axle one end is equipped with one grade of constant mesh gear, also is equipped with three on the I axle, the fourth gear cliding gear; II axle one end is equipped with and one grade of constant mesh gear gears in mesh, also is equipped with one on the II axle successively, second gear cliding gear and reverse gear cliding gear; Second gear ring gear, one grade of ring gear are installed on the III axle successively, and the III axle other end is equipped with fixed gear wheel; The IV axle mounting has whole drive pinion, fourth gear ring gear, and the end of IV axle is equipped with three, the reverse gear ring gear.
The rear end of described gear box is the garden arc.
The utility model adopt to be gone up structure, and I axle one end is equipped with one grade of constant mesh gear, also is equipped with three on the I axle, the fourth gear cliding gear; II axle one end is equipped with and one grade of constant mesh gear gears in mesh, also is equipped with one on the II axle successively, second gear cliding gear and reverse gear cliding gear; Second gear ring gear, one grade of ring gear are installed on the III axle successively, and the III axle other end is equipped with fixed gear wheel; The IV axle mounting has whole drive pinion, fourth gear ring gear, and the end of IV axle is equipped with three, the reverse gear ring gear.Make two gears only are installed on the I axle as power input shaft, one stressed less, be not easy to damage, and the constant mesh gear of the constant mesh gear of I axle and II axle and III axle, IV axle all is arranged at the end of I axle, II axle, III axle, IV axle, distribute along box bilateral wall, support by the two side, stressing conditions is good, has prolonged the service life of change speed gear box, and reverse gear realizes three grades of decelerations, increase transmitting ratio, reduce reverse speed, improve safety; The rear end of described gear box is the garden arc, and saving in material is in light weight, the intensity height.
