Abstract
The utility model discloses a gear box, in particular discloses a hydraulic reversing gear box of a mini-wheel loader. The hydraulic reversing gear box of the mini-wheel loader comprises a gear shift axle, an input axle and an output axle, and a shifting yoke with an internal tooth sleeve is movably fixed on the gear shift axle. The utility model is characterized in that a copper sleeve A, a copper sleeve B, and an input pinion gear and an input bull gear which are connected on the copper sleeve A and a copper sleeve B to rotate are respectively fixed at the left and right sides of the output axle, and an intermediate wheel is fixed in the middle of the output axle; an output bull gear and an output pinion gear which are meshed with the input pinion gear and the input bull gear are respectively fixed at the left and right sides of the output axle. In the utility model, a straight tooth cylindrical gear is replaced with a helical cylindrical gear to operate the meshing transmission, twin wheels are replaced with combination teeth to shift gear, thereby the transmission stability is increased, the noise is reduced, and the whole quality of the box body is improved.
Description
(1) technical field
The utility model relates to a kind of gearbox, particularly a kind of small sized loader hydraulic pressure commutation gearbox.
(2) background technique
Small sized loader (below 1.5 tons) is a kind of type that developed rapidly in nearly 2 years.Gearbox is a critical piece on the loader.Small sized loader hydraulic pressure commutation gearbox is exactly directly to drive gearbox with oil hydraulic motor to transfer by oil hydraulic motor positive and negative and realize advancing and retreating kinetic energy of loader.
The employed hydraulic pressure commutation of the existing small sized loader of China gearbox all adopts straight toothed spur gear, and gearshift is directly to stir the high low speed output that double linked wheel on the input shaft is realized gearbox.Stationarity is poor in the use, impact is big, and noise is big.The small gear on the double linked wheel particularly can only Gear Shaping, low precision (than the low 1-2 level of gear hobbing processing), and work efficiency is low.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of stable drive, small sized loader hydraulic pressure commutation gearbox that noise is little are provided.
The utility model is achieved by the following technical solution:
A kind of small sized loader hydraulic pressure commutation gearbox, comprise gearshift axle, input shaft, output shaft, the activity of going up of gearshift axle is fixed with the shift fork that has internal tooth casing, its special way is: the left and right sides of described input shaft is fixed with copper sheathing A, copper sheathing B respectively and connects input small gear and the input gearwheel that rotates thereon, and center fixed has breast wheel; The left and right sides of output shaft is fixed with respectively and imports small gear, imports output gearwheel and output pinion that gearwheel is meshed.
Small sized loader hydraulic pressure commutation gearbox of the present utility model, described input gearwheel, input small gear, output gearwheel, output pinion all adopt helical gear.
The utility model replaces the straight toothed spur gear engagement driving with helical gear, uses in conjunction with tooth to replace double linked wheel to shift gears, thereby has strengthened transmission stability, has reduced noise, has improved the total quality of casing.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 gearshift axle, 2 input small gears, 3 input shafts, 4 copper sheathing A, 5 internal tooth casings, 6 output gearwheels, 7 shift forks, 8 breast wheels, 9 copper sheathing B, 10 input gearwheels, 11 output shafts, 12 output pinions.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises gearshift axle 1, input shaft 3, output shaft 11, the movable shift fork 7 that has internal tooth casing 5 that is fixed with on the gearshift axle 1, the left and right sides of input shaft 3 is fixed with copper sheathing A4, copper sheathing B9 respectively and connects input small gear 2 and the input gearwheel 10 that rotates thereon, and center fixed has breast wheel 8; The left and right sides of output shaft 11 is fixed with respectively and imports small gear 2, imports output gearwheel 6 and output pinion 12 that gearwheel 10 is meshed.
During use, the input end of input shaft 3 directly and the oil hydraulic motor connection, the two ends of output shaft 11 respectively with two propeller shaft couplings of small sized loader.Input gearwheel 10 and input small gear 2 with output gearwheel 6 and output pinion 12, all adopt helical gear.When shift fork 7 during in the neutral position, 5 of internal tooth casings connect with breast wheel 8, and 3 of input shafts drive copper sheathing A4, copper sheathing B9, breast wheel 8 and internal tooth casing 5 and rotate, and input small gear 2 and input gearwheel 10 all do not rotate, and output shaft 11 does not change, i.e. neutral.When gearshift axle 1 spurs to the right, shift fork 7 drives internal tooth casing 5 and moves right, internal tooth casing 5 combines with breast wheel 8, input gearwheel 10 simultaneously, input shaft 3 drive breast wheels 8, internal tooth casing 5, input gearwheel 10, output pinion 12, output shaft 11 turn round simultaneously, output shaft 11 high speed rotating, i.e. high gear.Equally, when the axial left side of gearshift promotes, then import small gear 2 and drive 6 rotations of output gearwheels, output shaft 11 slowly runs, i.e. low gear.
Claims (2)
1. small sized loader hydraulic pressure commutation gearbox, comprise gearshift axle (1), input shaft (3), output shaft (11), gearshift axle (1) is gone up activity and is fixed with the shift fork (7) that has internal tooth casing (5), it is characterized in that: the left and right sides of described input shaft (3) is fixed with copper sheathing A (4), copper sheathing B (9) respectively and connects input small gear (2) and the input gearwheel (10) that rotates thereon, and center fixed has breast wheel (8); The left and right sides of output shaft (11) is fixed with respectively and imports small gear (2), imports output gearwheel (6) and output pinion (12) that gearwheel (10) is meshed.
2. small sized loader hydraulic pressure commutation gearbox according to claim 1 is characterized in that: described input gearwheel (10), input small gear (2), output gearwheel (6), output pinion (12) all adopt helical gear.
