Abstract
The utility model relates to a transitional transmission case assembly for power input of a wheel-type tractor; the transitional transmission case assembly is arranged between a clutch assembly and a gear box assembly, and the transitional case assembly comprises a transitional case, a driving gear, a driven gear and a transitional output shaft; the driving gear which is arranged on a clutch output shaft is meshed with the driven gear which is arranged on the transitional output shaft; the clutch output shaft and transitional output shaft which are separately connected with a clutch case and a transitional case are arranged along the altitude direction; the transitional output shaft which are extended out of the transitional case is connected with the gear box input shaft. The utility model can reduce the altitude position of the gear box input shaft and make the driver more comfortable with operation.
Description
Technical field
The utility model relates to a kind of actuating unit of wheeled tractor, especially relates to a kind of wheeled tractor power input transition transmission case assembly below 40 horsepowers.
Background technique
The tradition wheeled tractor, the power of motor is by the input shaft of clutch transmits to gearbox, after the speed stage of gearbox and torque adjustment, export back axle to, by final drive assembly power is reached wheel at last and bring into play tractive force, thereby realize the various functions of tractor.The power of four-wheel drive tractor below 40 horsepowers also is directly to reach gearbox from clutch, because the tractor overall structure is very compact, the operator cabin base plate can only be installed in the side of gearbox, the complete machine wheelbase is less in addition, driver's operating space is very little, so Joystick is laid between driver's two legs usually, passage is very narrow and small, in disorder owing to get on and off, cause the driver to get on and off and operate inconvenience, operation comfort is poor, especially can not be adapted to the big driver's of the bodily form operation.
Summary of the invention
The purpose of this utility model provides and a kind ofly can reduce gearbox input shaft height and position, improves the wheeled tractor power input transition transmission case assembly of driver's operation travelling comfort.
The utility model for the technological scheme that achieves the above object is: a kind of wheeled tractor power input transition transmission case assembly, described transition transmission case assembly is installed between clutch assembly and the transmission assembly, transition transmission case assembly comprises the transition casing, driving gear, driven gear and transition output shaft, be installed in driving gear and the driven gear engagement that is installed on the transition output shaft on the clutch output shaft, be connected to clutch output shaft on clutch casing and the transition casing and transition output shaft along the short transverse setting, the transition output shaft that extends the transition casing is connected with the gearbox input shaft.
The utility model has increased a transition transmission case assembly between clutch assembly and transmission assembly, the outputting power of clutch is through clutch output shaft, driving gear, driven gear and transition output shaft reach the gearbox input shaft, because driving gear and driven gear are to arrange along short transverse, can not only increase distance between driver seat and the steering wheel, simultaneously also export height and position into axle because of having reduced gearbox, make the floor of tractor can be arranged in a lower plane, on having increased, the channel space size of getting off has satisfied the driver to the operating space size requirement.The utility model is owing to increased transition transmission case assembly, the floor of tractor is arranged in the plane, avoid the state of formation step in plane on traditional tractor floor and the gearbox, made that the passage that gets on and off of tractor is unimpeded, improved driver's operation comfort.
