Detailed Description
As can be seen from FIGS. 1 and 2, the present invention comprises an engine assembly 1, a transmission assembly 2, a main transmission shaft 3, a comprehensive transmission case 4, a front transmission shaft 5a, a rear transmission shaft 5b, a pump propeller transmission shaft 6, a front differential assembly 7a, a rear differential assembly 7b, a transmission half shaft 8, a sprocket assembly 9, a chain 10, a connecting shaft assembly 11, an outer transmission half shaft 12, a hub assembly 13, a brake assembly 14 and a water jet pump/propeller 15, wherein the engine assembly 1 and the transmission case assembly 2 are connected into a whole.
As also shown in fig. 1 and 2, in order to realize ' land running ' and ' water surface floating and the realization of all-wheel drive and time-sharing drive during the land running, a comprehensive gearbox (4) with three functions of ' transfer, speed change and time sharing ' is specially and selectively arranged.
As shown in fig. 1 and 2, in order to facilitate the convenient assembly of the integrated transmission case 4 with various types of engine assemblies 1 and transmission case assemblies 2, a main transmission shaft 3 is specially arranged.
As also shown in fig. 1 and 2, in order to realize the "all-wheel drive" and the "time-sharing drive" in the "land travel" state, a front propeller shaft 5a, a rear propeller shaft 5b, a front differential assembly 7a, and a rear differential assembly 7b are provided, and the sprocket assemblies 9 on the first shaft and the second shaft are connected to each other by a chain 10, and the sprocket assemblies 9 on the third shaft and the fourth shaft are connected to each other.
As can be seen from fig. 1, 2, 3, 4 and 5, in order to transmit the power (torque) of the engine to each wheel and the water jet pump or the propeller, a comprehensive transmission case 4 having three functions of "transfer, speed change and time division" is specially installed.
After power (torque) from an engine assembly 1 is transmitted into a comprehensive gearbox 4 through a gearbox assembly 2 and a main transmission shaft 3, the transmission of the power (torque) to a pump propeller transmission shaft 6 can be quickly cut off through manual transfer operation, so that a land driving state of a power (torque) transmission mode is realized.
In the all-wheel drive mode in the land driving state, the power (torque) of the engine (through the manual all-wheel drive operation of the integrated transmission case 4) rotates together through the front transmission shaft 5a and the rear transmission shaft 5b which are positioned at the front end and the rear end of one side of the integrated transmission case 4, the front differential assembly 7a and the rear differential assembly 7b, the transmission half shaft 8, the chain wheel assembly 9, the chain 10, the connecting shaft assembly 11 and the outer transmission half shaft 12, and the (8) wheel hub assemblies 13.
In the time-sharing driving mode of the 'land driving' state, the power (torque) of the engine (through the time-sharing driving operation of the integrated transmission case 4) is transmitted only to the rear transmission shaft 5b at the rear end of one side of the integrated transmission case 4, and is transmitted to the rear differential assembly 7b, the transmission half shaft 8, the chain wheel assembly 9, the chain 10, the connecting shaft assembly 11, the outer transmission half shaft 12 and the hub assembly(s) 13 driving the third shaft and the fourth shaft to rotate together.
As further shown in fig. 1, 2, 3, 4 and 5, the power (torque) from the engine assembly 1 is transmitted to the integrated transmission 4 through the transmission assembly 2 and the main transmission shaft 3, and then is manually transferred to cut off the transmission of the power to the front transmission shaft 5a and the rear transmission shaft 5b, so as to realize the "water surface floating" state of the "power (torque) transmission mode".
In the water surface floating state, the power (torque) of the engine is directly transmitted to the water spraying pump/propeller 15 through the pump propeller transmission shaft 6 connected with the comprehensive transmission case 4.
As further shown in fig. 1, 2, 3, 4 and 5, in order to realize the brake in the "land driving" state, the brake assembly(s) 14 are sequentially and fixedly mounted on the rotating shaft of the connecting shaft assembly(s) 11.
As further shown in fig. 1, 2, 3, 4 and 5, the (4) wheels on one side of the vehicle are braked simultaneously, so that the rotation speed of each wheel on the side can be slowed down or stopped, the left (or right) side of the whole vehicle can be smoothly steered, and the turning radius of the vehicle can be reduced remarkably.
As is further known from fig. 1, 2, 3, 4 and 5, the power transmission system can be widely applied to power transmission of multi-wheeled amphibious vehicles such as 8x8, 8x6, 6x6 and 6x4 due to the significant characteristics.
