[0024] An input flange 2 is provided inside the transmission housing 1, an input shaft 3 is provided on the outside of the input flange 2, a first connecting gear 4 is provided on the outside of the input shaft 3, a second connecting gear 5 and a third connecting gear 6 are respectively meshed with the outside of the first connecting gear 4, a friction clutch 7 is provided on one side of the second connecting gear 5 and the third connecting gear 6, a high-speed input shaft assembly 8 and a low-speed output shaft assembly 9 are respectively provided on one side of the two friction clutches 7, a high-speed input shaft assembly 8 is connected to a high-speed gear selection output shaft assembly 11 on one side of the high-speed input shaft assembly 8, a low-speed gear selection output shaft assembly 10 is connected to one side of the low-speed gear selection output shaft assembly 9, a transfer connecting gear 12 is provided on one side of the low-speed gear selection output shaft assembly 10 and the high-speed gear selection output shaft assembly 11, a pump connecting gear 14 is meshed with the outside of the transfer connecting gear 12, and a pre-installed output shaft assembly 13 is provided inside the pump connecting gear 14;

[0025] A friction clutch assembly 15 is provided inside the transmission housing 1. A clutch main shaft 16 is provided on one side of the friction clutch assembly 15. An input shaft assembly 17 is provided on one side of the clutch main shaft 16. A gear selection area output shaft assembly 18 is provided on one end of the input shaft assembly 17.

[0026] A dual main shaft assembly 19 is provided inside the gearbox housing 1, and a gear selection area main shaft assembly 20 is provided on one side of the dual main shaft assembly 19;

[0027] The rear axle output flange 21 and the front axle output flange 22 are arranged inside the gearbox housing 1.

[0028] A first sliding sleeve 23 is provided on the outer side of the clutch main shaft 16 , and a second sliding sleeve 24 is provided on the outer side of one end of the gear selection area output shaft assembly 18 .

[0029] The gearbox is directly connected to the dual-spindle transfer case assembly flange input shaft through the output shaft flange to connect the connecting gear, and the separation clutch is connected through the connecting gear. The clutch drives or switches high and low gears, and then the gear is selected through the transition of the sliding sleeve. Different gears selected by the sliding sleeve switch different gears, and finally the output is output to the output shaft to drive the front axle or rear axle to drive the vehicle.

[0030] It should be noted that this system utilizes two friction clutch assemblies, directly connected to the transmission flange. A connecting gear within the flange drives the clutch mainshaft, and the clutch controls the engagement and disengagement of the mainshaft via a clutch plate. This clutch controls the operation of the internal dual-mainshaft transfer case. The dual-mainshaft structure provides varying power through the shifting of gear ratios. Slip sleeves installed between the gears, controlled by a shift fork, enable gear selection to meet user requirements. This system features a main and auxiliary transfer case. The main transfer case serves as the selector area, while the auxiliary transfer case serves as the shifting area. The selector area and the shifting area each have high and low ranges. The selector area selects gears, while the shifting area allows for fine-tuning of speeds between gears. Both the main and auxiliary transfer cases offer eight selectable gears, all of which can be used interchangeably, enabling geometric gear shifting during operation. Furthermore, the dual-mainshaft system provides greater power and torque. This system is externally configured with a rear power output system. The rear power output system achieves the function of part-time four-wheel drive through structural design. The advantage of the separation design is that the vehicle can run stably, the operation is flexible, and the replacement is convenient. Then the vehicle can be driven in two-wheel drive or four-wheel drive selectively as needed to achieve the purpose of part-time four-wheel drive. The front and rear axles are pneumatically driven in a part-time manner. By starting the air chamber connection mechanism, either two-wheel drive or four-wheel drive can be achieved to change the working state of the vehicle's gearbox according to demand. At the same time, it will not affect the vehicle's driving speed or stability, so that the vehicle can achieve more efficient and economical operation.

[0031] Working principle:

[0032] 1. First refer to Figure 4As shown, the gearbox is connected to the input flange 2, and drives the first connecting gear 4 through the input shaft 3. The first connecting gear 4 drives the second connecting gear 5 or the third connecting gear 6 respectively. A friction clutch 7 is installed on the second connecting gear 5 or the third connecting gear 6. The high-speed input shaft assembly 8 or the low-speed output shaft assembly 9 is driven by the clutch of the friction clutch 7, and then connected to the high-speed gear selection output shaft assembly 11 or the low-speed output shaft assembly 9 through the sliding sleeve, and output to the transfer connecting gear 12, and finally through Figure 5 The gear selection area output shaft assembly 18 is connected to the rear output transfer case to drive the rear axle output flange 21 and the front axle output flange 22 to connect the front axle or the rear axle;

[0033] 2. Figure 5 The working principle of the dual-spindle gearbox is as follows: when the friction clutch assembly 15 (the friction clutch assembly has a high-speed range and a low-speed range, see Figure 4 , the high-range assembly and the low-range assembly have the same structure, but the transmission ratio is different) When the high-range is connected, the low-range friction clutch assembly is disengaged, and then drives the clutch main shaft 16. At this time, the first sliding sleeve 23 is separated from the clutch main shaft 16 at the same time, and then the gear on the clutch main shaft 16 drives the dual-main shaft assembly 19 to transmit. Because the directions of the dual main shafts are in the same direction, the transmission of the dual main shafts drives the input shaft assembly 17. Since there is a sliding sleeve on the input shaft assembly 17 to split the gear, different transmission ratios are formed and transmitted to the gear selection. The second sliding sleeve 24 is separated from the high-speed zone, so the power is transmitted to the selector zone main shaft assembly 20 through the connecting gear on the high-speed zone input shaft assembly. Since the selector zone main shaft assembly 20 is in the same direction, it synchronously drives the selector zone output shaft assembly 18. Then, the sliding sleeve selects different transmission ratios through the output gear and transmits it to the rear transfer case assembly. After internal conversion in the rear transfer case assembly, it drives the rear axle output flange 21 and the front axle output flange 22 to drive the front and rear axles respectively. This dual-spindle structure is characterized by the dual-spindle transmission that can effectively multiply the gear torque, making the gearbox more stressed.

[0034] 3. Figure 5 Similarly, when the friction clutch assembly 15 (the friction clutch assembly has a high-speed range and a low-speed range, see Figure 4 , the high-range assembly and the low-range assembly have the same structure, but the transmission ratio is different) When the high-range is disengaged, the low-range friction clutch assembly is engaged, and the working principle is the same as Article 2;

[0035] 4. Figure 5 Similarly, when the friction clutch assembly 15 (the friction clutch assembly has a high-speed range and a low-speed range, see Figure 4(The high-range assembly and the low-range assembly have the same structure, but different transmission ratios.) When the high-range and low-range areas are disengaged at the same time, the first sliding sleeve 23 of the low-range or high-range area is connected to the clutch main shaft 16, and the gear-engaging sliding sleeve is connected to the input shaft, which directly outputs to the rear transfer case assembly, and then drives the rear axle flange and the front axle flange of the rear transfer case assembly;

[0036] This utility model utilizes two friction clutch assemblies to drive a dual-spindle connection system for high and low gears. This system then connects to a gear-engaging sleeve via internal gears as needed to achieve high and low gears and select gears, enabling multiple gear selections. The dual-spindle system multiplies torque, which is then transmitted to the output flange via the rear power transfer case assembly, driving the front and rear axles, thereby enhancing torque and power while the vehicle is in motion.
