Abstract
The invention discloses a transfer case comprising a case body. The case body is provided with a power input shaft therein, and the power input shaft is provided with a driving gear, and one end of the power input shaft extend out of a power input side of the case body; at least two output shafts surrounding the power input shaft are parallel to the power input shaft and provided with a driven gear; the driving gear is meshed with the driven gear; the transfer case also comprises a connecting device arranged on the extending end of the power input shaft and used for connecting an engine flywheel. The transfer case has small size, occupies small space, and can be transversely arranged on a tail of a rear chassis after being connected with the engine and a common gear pump, and a whole powertransmission device has compact structure, can reduce size of a whole loader, raw material consumption and manufacturing cost.
Description
Technical field
The present invention relates to a kind of transfer case, relate in particular to the transfer case that loader a kind of and that motor is supporting is used.
Background technique
The power transmission system of the loader of prior art adopts rear-mounted usually, drive gearbox by motor, gearbox is connected with a treble pump, treble pump changes the mechanical energy of motor output into the hydraulic pressure energy, drives equipment, traveling gear and the steering gear of loader respectively by three hydraulic pressure output pipes.But the defective that this mode exists is: the size of gearbox and treble pump is all bigger, and occupation space is big, and is difficult to cross setting after motor is connected; Under the situation that whole actuating unit vertically is provided with, strengthened the longitudinal size of loader complete machine, increased manufacture cost.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of transfer case at above-mentioned defective, bigger with the size of the gearbox that solves prior art and treble pump, occupation space is big, with the problem that is difficult to cross setting after motor is connected.
For solving the problems of the technologies described above, technological scheme of the present invention is: transfer case, be installed on the flywheel end of motor, comprise casing, described casing has the power input side, be provided with power input shaft in the described casing, on the described power input shaft driving gear be installed, an end of described power input shaft stretches out the power input side of described casing; At least two output shafts around described power input shaft, described output shaft is parallel with described power input shaft, on the described output shaft driven gear is installed; Described driving gear and the engagement of described driven gear; Described transfer case also comprises the connection set that is connected with engine flywheel of being used for of the external part that is installed on described power input shaft.
As optimized technical scheme, described connection set comprises and being used for and bolted land of engine flywheel and the adpting flange that is used for being connected with the power input shaft key that described land is fixedlyed connected with adpting flange is removable.
As optimized technical scheme, described output shaft has three and annular uniform.
As optimized technical scheme, described driving gear is identical with described driven gear.
Owing to adopted technique scheme, the invention has the beneficial effects as follows: owing to be provided with power input shaft in the described casing, on the described power input shaft driving gear is installed, an end of described power input shaft stretches out the power input side of described casing; At least two output shafts around described power input shaft, described output shaft is parallel with described power input shaft, on the described output shaft driven gear is installed; Described driving gear and the engagement of described driven gear; Described transfer case also comprises the connection set that is connected with engine flywheel of being used for of the external part that is installed on described power input shaft.Wherein, described connection set comprises and being used for and bolted land of engine flywheel and the adpting flange that is used for being connected with the power input shaft key that described land is fixedlyed connected with adpting flange is removable.During use, the land of transfer case is connected with the flywheel of motor by bolt, thereby and make the adpting flange of fixedlying connected drive the power input shaft revolution with it with flywheel revolution, driven gear on driving gear on the power input shaft and described at least two output shafts meshes and the revolution of drive output shaft, preferred described output shaft is three, described three output shafts are connected than the little a lot of full depth tooth wheel pump of treble pump with a size respectively, transfer case is given three full depth tooth wheel pumps with the power distribution of motor, drive the equipment of loader more respectively by the hydraulic pressure output pipe, traveling gear and the steering gear, because transfer case is less with the size after three full depth tooth wheel pumps are connected, occupation space is little, motor, transfer case and the afterbody that can be horizontally installed on the back vehicle frame after the full depth tooth wheel pump is connected, whole actuating unit compact structure, can reduce the longitudinal size of loader complete machine, reduce consumption of raw materials, reduce manufacture cost, also play the counterweight effect simultaneously, be convenient to safeguard maintenance after opening hood.
