Problems solved by technology

[0002] The commonly used power output of tractors on the market is the rear PTO output. Of course, there are also machines that require front power output. The current implementation method is to drive the tractor in reverse, which greatly reduces the comfort and handling performance of the tractor, and some models Due to the small body of the whole machine, reverse driving cannot be realized
[0003] At present, most of the gearboxes of power output devices in the domestic market use electromagnetic clutches, which have complex structures, increased machine mass, and large loss of transmission efficiency. convenient

Embodiment 1

[0033] like figure 1 and figure 2 As shown, the present invention provides a front PTO transmission system, including a power output shaft 1 and an input gear 2, the power output shaft 1 can rotate around its own axis; the input gear 2 is coaxially rotated and sleeved on the power output shaft 1 It is combined with the power output shaft 1 through a hydraulic clutch and rotates with the power output shaft 1 or is separated from the power output shaft 1.

[0034] During transmission, the power is input by the input gear 2, and then the input gear 2 is combined with the power output shaft 1 through the hydraulic clutch and rotates with the power output shaft 1 to realize the rapid output of power; or separate from the power output shaft and stop the transmission, the structure is simple , the design is reasonable.

[0035] This embodiment can realize fast output of power, high transmission efficiency, compact structure, high integration, small occupied space and light weight....

Embodiment 2

[0038] On the basis of Embodiment 1, in this embodiment, the hydraulic clutch includes a hydraulic drive mechanism and a friction plate assembly, one end of the input gear 2 extends to the other end of the power output shaft 1, and a mounting cavity is formed between the input gear 2 and the power output shaft 1 , that is, the input gear 2 has a cylindrical structure with one end closed and one end open, and a circular hole is arranged at the center of the closed end, and the circular hole is rotatably connected with the power output shaft 1 through a bearing; the friction plate assembly is installed on the power output shaft 1 Corresponding to the parts in the installation cavity, and are respectively connected with one end of the power output shaft 1 and one end of the input gear 2; the hydraulic drive mechanism is used to drive the friction plate assembly to combine or separate the power output shaft 1 and the input gear 2.

[0039] During transmission, the friction plate as...

Embodiment 3

[0042] On the basis of Embodiment 2, in this embodiment, the friction plate assembly includes a plurality of friction plates 3 and a plurality of steel plates 4 , and the plurality of friction plates 3 and the plurality of steel plates 4 are alternately coaxial along the axial direction of the power output shaft 1 . It is sleeved on one end of the power output shaft 1, and can slide along the axial direction of the power output shaft 1 respectively; the inner sides of the plurality of friction plates 3 are respectively provided with internal teeth meshing with the external teeth on one end of the power output shaft 1. The outer teeth of each steel plate 4 are respectively provided with external teeth meshing with the internal teeth on the inner side of one end of the input gear 2 .

[0043] During transmission, a plurality of friction plates 3 are respectively meshed with the power output shaft 1, and a plurality of steel plates 4 are respectively meshed with the input gear 2. ...

Abstract

The invention relates to a front PTO transmission system, a transmission case and a tractor, the PTO transmission system comprises a power output shaft and an input gear, and the power output shaft can rotate around the axial direction of the power output shaft; the input gear coaxially and rotatably sleeves one end of the power output shaft, is combined with the power output shaft through the hydraulic clutch and rotates along with the power output shaft or is separated from the power output shaft. The power transmission device has the beneficial effects that power can be rapidly output, the transmission efficiency is high, the structure is compact, the integration degree is high, the occupied space is small, and the weight is light.

Description

technical field [0001] The invention relates to the technical field of transmission systems, in particular to a front PTO transmission system, a transmission case and a tractor. Background technique [0002] The commonly used power output of tractors on the market is the rear PTO output. Of course, when there are appliances that require front power output, the current implementation method is the reverse driving of the tractor. The comfort and handling performance of the reverse driving tractor are greatly reduced, and some models. Due to the small body of the whole machine, reverse driving cannot be achieved. [0003] At present, most of the gearboxes of the front PTO in the domestic market use electromagnetic clutches, which have complex structures, increased machine mass, and large loss of transmission efficiency. convenient. SUMMARY OF THE INVENTION [0004] The technical problem to be solved by the present invention is to provide a front PTO transmission system, a t...
