Abstract
The utility model relates to a gearshift, in particular to a working gearshift of engineering machinery. The utility model is characterized in that a second gear wheel is fixed on an input shaft, a first gear wheel is fixed on an intermediate shaft which is parallel to the input shaft, the first gear wheel and the second gear wheel are meshed with each other, the third gear wheel of the intermediate shaft is a bevel gear wheel, and the third gear wheel is meshed with another bevel gear which is the fourth gear wheel; the fourth gear wheel is meshed and connected with the output shaft tooth and is parallel to the input shaft; the fourth gear wheel fixed on the output shaft is movably connected with the output shaft through a shifting device. The working gearshift of engineering machinery has simple and compact structure.
Description
Technical field: the utility model relates to a kind of speed changer, particularly a kind of engineering machinery work speed changer.
Background technique: engineering machinery such as pavement milling machine, in vehicle driving, and when not repairing the road surface, diesel engine can not stop, the power of passing to speed changer this moment must be placed on gearshift its power of neutral position and just not pass to milling machine, when need work, its gearshift mechanism is placed the work gear, milling machine work.
Summary of the invention: the purpose of this utility model provides a kind of engineering machinery work speed changer, so that have simple in structure, compact purpose.
The purpose of this utility model is to realize like this, engineering machinery work speed changer, it is characterized in that: it comprises second gear that is fixed on input shaft, with first gear of second wheel tooth engagement, first gear is fixed on the jack shaft parallel with input shaft, jack shaft the 3rd gear, the 3rd gear is a cone gear, both the 4th wheel tooth engagements of the 3rd gear and an other cone gear, the 4th gear and output shaft tooth are connected with a joggle, and it is parallel with input shaft; The 4th gear and the output shaft that are fixed on output shaft flexibly connect by gearshift.
Working procedure of the present utility model is: when not repairing the road surface in vehicle driving, diesel engine can not stop, and gearshift is in empty position, and just the 4th gear is not connected with output shaft; This moment, power drove second gear on the input shaft, drive first gear again by second gear and rotate, the 3rd gear that drives when first gear rotates on the jack shaft rotates, and the 3rd gear is a cone gear, be engaged with the 4th gear with its vertical teeth, at this moment it does not rotate output shaft.And when gearshift was in work, the 4th above-mentioned gear was connected with output shaft, just imported power by first gear, second gear, the 3rd gear, the 4th gear, and power is passed to output shaft, drove milling machine work by output shaft.
Because the utility model is by first gear, second gear, the 3rd gear, the 4th gear, realize the work of speed changer with gearshift and do not work, when passing through gearshift, when making output shaft " work ", the 4th gear and output shaft tooth are thrown off, and power is by primary cylinder gear and one-level cone gear, and this moment, bevel gear wheel dallied on output shaft, power is not passed to output shaft, and it has simple in structure, compact characteristics.
Below in conjunction with accompanying drawing content of the present utility model is described in detail.
Description of drawings: Fig. 1 is the utility model embodiment's a structural representation.
Among the figure, 1, first gear; 2, second gear; 3, input shaft; 4, jack shaft; 5, output shaft; 6, the 3rd gear; 7, the 4th gear; 8, gearshift.
Embodiment: as shown in Figure 1, when gearshift 8 is positioned at " not working ", at this moment, the 4th gear 7 is thrown off with output shaft 5 teeth, and at this moment second gear 2 on the power drive this moment input shaft 3 drives first gear 1 again by second gear 2 and rotates, the 3rd gear 6 that first gear 1 drives when rotating on the jack shaft 4 rotates, the 3rd gear 6 is a cone gear, and it and the 4th wheel tooth mesh, and it is moving only to do idle running.
When gearshift 8 is positioned at " work ", at this moment, the 4th gear 7 and the engagement of output shaft 5 teeth, at this moment power drives second gear 2 on the input shaft 3, drive first gear 1 again by second gear 2 and rotate, the 3rd gear 6 that first gear 1 drives when rotating on the jack shaft 4 rotates, and the 3rd gear 6 is a cone gear, it and the 4th gear 7 teeth mesh, and the 4th gear 7 drives input shafts 3 and rotates.Thereby can make power pass to output shaft 3, drive milling machine work by output shaft 3.
