Fig. 12 to 13 are a structural diagram and a schematic diagram of a dual power system according to an embodiment of the present invention, which includes two sets of power systems, i.e. a first power system and a second power system, both sets of power systems being disposed in the new power vehicle main body: the first power system includes: the system comprises a diesel engine A, a generator and a controller, a special power battery, a driving motor and a controller, wherein one end of a reduction gearbox assembly is connected with the driving motor through a spline, the other end of the reduction gearbox assembly is connected with a main speed reducer assembly through a spline, and a front axle hub speed reducer assembly is respectively connected with the main speed reducer through a transmission shaft.
The second power system includes: the second engine is combined with the AT gearbox, the transfer case is combined with the intermediate axle main reducer assembly, the AT gearbox is connected with the transfer case through a driving shaft, the intermediate axle main reducer assembly is connected with the driving shaft through the shaft, and the driving shaft is connected with the rear axle main reducer assembly. The middle and rear axle wheel-side reducer assemblies are respectively connected with the main reducer through a transmission shaft.
The double-engine chassis is arranged: at the front axle, each chassis assembly is mainly arranged under the vehicle body floor of a cockpit and a combat cabin, and a driving motor, a reduction gearbox and a front axle main reducer are connected through splines. In the power cabin, an engine B, an automatic gearbox and a transfer case are arranged in the middle of the power cabin; the engine A and the generator are arranged on the right side of the engine B; the middle axle main reducer and the rear axle main reducer are arranged below the engine B and the automatic gearbox sub-assembly; the main and auxiliary oil tanks are respectively arranged between the left, right, middle and rear wheels; the power battery is arranged at the left rear part of the whole vehicle; the intermediate frequency power supply box is arranged above the transfer case and close to the left; the rest of the system is fixed in place according to space and clearance requirements.
The novel power special vehicle of the embodiment of the invention adopts the double power systems, thus achieving the purpose of unit redundancy, ensuring the whole vehicle operation of the vehicle under the condition that one power system fails, and avoiding the occurrence of mechanical breakdown accidents to the maximum extent; the system is provided with three power transmission modes which can be switched among a 6 × 2 mode, a 6 × 4 mode and a 6 × 6 mode. The high-speed or large-load running can adopt 6x6 driving, the good road surface middle-speed running can adopt 6x4 driving, and the good road surface low-speed running can adopt 6x2 driving.
Implementing shift logic that can switch between 6 × 2 mode, 6 × 4 mode, 6 × 6 mode: the transfer case and the reduction gearbox are respectively provided with a high gear, a low gear and an idle gear. The gears of the transfer case and the reduction gearbox are controlled by the vehicle control unit. The principle of the transfer case and the reduction gearbox is that except the control of corresponding switches, when only one set of power system drives a vehicle, the gear of the other set of power system must be forced to be neutral through a corresponding neutral forced switch. When only the traditional power works, the gear of the transfer case is controlled by the control switch, and the reduction gearbox is forced to be in a neutral position; when the transfer case is in a hybrid electric drive or hybrid series mode, the transfer case and the reduction gearbox are at the same height and the same low and are controlled by the control switch. And the operation of gears is forbidden in the driving process, and if the gear shifting switch is operated, the gears of the transfer case and the reduction gearbox do not respond.
On the basis of the above embodiment, the first power system of the embodiment of the invention further includes: special power battery, intermediate frequency power supply box and vehicle control unit. The generator, the special power battery and the intermediate frequency power box are connected through a high-voltage cable. The medium-frequency power box can convert alternating current generated by the generator into medium-frequency power and supply power to the vehicle-mounted high-power equipment. The EMS of the engine receives a signal of controlling the VCU of the whole vehicle, and the constant rotating speed of the engine is realized through closed-loop control inside the engine, so that the power generation quality is ensured. The generator A can charge the special power battery, and can realize silent running without the operation of the engine, namely the special power battery directly starts the driving motor to realize the 6X2 silent running mode of the whole vehicle. The vehicle control unit CAN realize the control of the engine A, the generator, the driving motor, the intermediate frequency power box and the special power battery through the CAN line. The intention of a driver is judged by recognizing a finished automobile pedal signal, and the rotating speed and the torque of the double engines, the generators and the driving motors are coordinately controlled, so that different requirements on the dynamic property and the economical efficiency of the finished automobile can be met.
The second power system drives a middle axle and a rear axle of the whole vehicle, the middle axle is connected with the rear axle through a transmission shaft, and the first power system drives a front axle of the whole vehicle. The front axle is rigidly connected with the middle rear axle without a transmission shaft, so that the arrangement space of the whole vehicle is more flexible.
The first power system is independently started to realize a 6X2 driving mode of the whole vehicle, and the second power system is independently started to realize a 6X4 driving mode of the whole vehicle. In order to prevent the damage of parts caused by the back dragging of the whole vehicle to the front axle when the first power system is independently started, the back dragging of the whole vehicle to the middle rear axle and the independent starting of the second power system, the system is provided with neutral gears on the reduction gearbox and the transfer case, and the whole vehicle can normally run when the two systems are independently driven. When the first power system and the second power system are started simultaneously, a 6X6 driving mode of the whole vehicle can be realized.
The special vehicle with the double power systems can ensure that the whole vehicle can continuously run under the condition that a single power system fails. The double engines are reasonably matched, and compared with the whole vehicle arrangement of a single high-power engine, the length of the whole vehicle can be effectively shortened, and the weight of the whole vehicle is reduced; the fuel consumption can be effectively reduced through reasonable control of the double engines and the motors; the engine A can generate power with full power and output the power to the vehicle-mounted electric equipment, the output power is high, the power generation quality is high, and power generation during traveling can be realized.
It should be understood that the above are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention disclosed herein should be covered within the scope of the present invention.
