Background
At present, multi-wheel and crawler-type amphibious vehicles manufactured at home and abroad are generally provided with a transmission case with a hydraulic torque conversion function in order to realize stable power transmission and steering. Although the transmission case has high transmission efficiency, the transmission case has large volume, heavy weight and very expensive selling price, thereby being difficult to meet the special requirements of developing light amphibious vehicles and boats at home and abroad.

The invention aims to provide a hydraulic comprehensive transmission case which has scientific design, reasonable structure, excellent performance and low cost and can better meet the power distribution and transmission requirements of various light amphibious vehicles and boats, and the transmission case has three functions of transfer, clutch and speed change, is simple to operate and control, convenient to assemble and disassemble, easy to maintain and high in cost performance.
The invention adopts the following technical scheme to achieve the purpose of the invention. A hydraulic integrated transmission case comprises a case 1, an input shaft 2, a driving gear 3, a driven gear I4, a bolt 5, a hydraulic clutch I6, a rotary joint I7, an output shaft I8, a driven gear II 9, a hydraulic clutch II 10, a rotary joint II 11, an output shaft II 12 and a controller 13. Wherein
A driving gear 3 is fixedly arranged on an input shaft 2, a driven gear I4 is fixedly arranged on a rotating body 6e of a hydraulic clutch I6 through a bolt 5, a driven gear II 9 is fixedly arranged on a rotating body 10e of a hydraulic clutch II 10 through a bolt 5, and the driving gear 3, the driven gear I4 and the driven gear II 9 are in a normally meshed state.
The hydraulic clutch I6 is sequentially composed of a central shaft 6a, a piston 6b, a spring 6c, a friction plate 6d and a rotating body 6e, an oil delivery hole 6f communicated with the rotating joint I7 is formed in the central shaft 6a, a spline is arranged on the outer surface of the oil delivery hole, the spline is also arranged on an inner hole of the friction plate 6c, the friction plate 6c is sequentially sleeved on the central shaft 6a, the rotating joint I7 is fixedly arranged at one end of the central shaft 6a, and an output shaft I8 is sequentially inserted into the other end of the central shaft 6a through the spline.
The hydraulic clutch II 10 is composed of a central shaft 10a, a piston 10b, a spring 10c, a friction plate 10d and a rotating body 10e in order, an oil delivery hole 10f communicated with the rotary joint II 11 is arranged in the central shaft 10a, a spline is arranged on the outer surface of the central shaft, a spline is also arranged on an inner hole of the friction plate 10c, the friction plate 10c is sleeved on the central shaft 10a in order, the rotary joint II 11 is fixedly arranged at one end of the central shaft 10a, and an output shaft II 12 is inserted at the other end of the central shaft 10a in order through the spline.
The input shaft 2, the hydraulic clutch I6, the output shaft I8, the hydraulic clutch II 10 and the output shaft II 12 are sequentially movably arranged in the transmission box body 1.
The working principle of the hydraulic clutch I6 is as follows: the 'pressurization suction', namely, the hydraulic oil flows into the central shaft 6a through the rotary joint I7 of the rotary joint through the controller 13, the piston 6b can be rapidly pushed by the oil pressure of 24Bar, so that the friction plate 6c and the rotary body 6e are sucked (the spring 6d is pressed when in a suction state); the "pressure relief release" is a state in which the hydraulic oil is discharged from the center shaft 6a through the rotary joint i 7 by the controller 13, and the friction plate 6c is rapidly released from the rotary body 6e by the urging force of the spring 6d (released state).
The hydraulic clutch II 10 and the hydraulic clutch I6 are of the same structure, so that the working principle is completely the same.
When the hydraulic clutch I6 is in the attraction state, the driving gear 3 drives the driven gear I4, the rotating body 6e, the friction plate 6d, the central shaft 6a and the output shaft I8 to run together, and when the hydraulic clutch I6 is in the separation state, the driving gear 3 only can drive the driven gear I4 and the rotating body 6e to idle, and the output shaft I8 does not run.
Similarly, when the hydraulic clutch ii 10 is in the attraction state, the driving gear 3 drives the driven gear ii 9, the rotating body 10e, the friction plate 10d, the central shaft 10a and the output shaft ii 12 to rotate together, and when the hydraulic clutch ii 10 is in the separation state, the driving gear 3 can only drive the driven gear ii 9 and the rotating body 10e to idle, and the output shaft ii 12 does not rotate.
Due to the adoption of the technical scheme, the invention perfectly achieves the aim. It has the following outstanding advantages (i.e. beneficial effects) compared with similar products.
1. The design is scientific, the structure is reasonable, and the requirement of one machine with double pumps for power transmission is better met.
2. The operation is simple, and the input shaft 2 can quickly and stably transmit and interrupt torque during operation.
3. When the vehicle is running on the water (interrupting the torque transmission of one of the hydraulic clutches), the turning radius of the vehicle can be significantly reduced.
4. Convenient disassembly and easy manufacture and maintenance.

Similarly, the hydraulic oil can be made to flow out from the central shaft 6a and the central shaft 10a through the rotary joint i 7 and the rotary joint ii 11 by the controller 13, and the friction plate 6c and the friction plate 10c are quickly separated from the rotary body 6e and the rotary body 10e under the action of the spring 6d and the spring 10d, so that the output shaft i 8 and the output shaft ii 12 are not operated.
As also shown in fig. 1 and 2, the torque speed ratio of the input shaft 2 to the output shafts i 8 and ii 12 can be changed by setting and adjusting the number of teeth of the driving gear 3 and the driven gear i 4, and the driven gear ii 9.
