Description

Technical Field

[0001] The utility model relates to the technical field of vehicle power supplies, in particular to an integrated traveling power take-off power generation system for a gearbox. Background Art

[0002] At present, vehicle power take-off power generation systems are divided into two categories according to the installation platform. One category is installed on the old second-generation military vehicles, and the other category is installed on the third-generation military vehicles, that is, high-mobility chassis vehicles. Traditional domestic vehicle power take-off power generation systems are also divided into two major categories: traveling power take-off power generation and parking power take-off power generation. Traveling power take-off power generation means that when the vehicle is moving, it is necessary to supply power to electrical equipment, such as a communication command vehicle. Another is a parking power take-off power generation system. Mainly when the vehicle stops and is far from the urban area, the engine of the vehicle chassis itself is used to drive the generator to rotate and generate electricity to provide stable electric energy for the load. At the current domestic technical level, according to the installation method, it is also divided into two major categories:

[0003] One category is a small-power generator with a power of 3 kW to 8 kW. The silicon rectifier generator is installed on the vehicle chassis with small power requirements. The generator is installed in the engine compartment and takes power from the crankshaft of the engine, and drives the generator to generate electricity externally through belt drive.

[0004] The other category is a generator with a relatively large power of 8 kW to 300 kW. Mainly, a power take-off device, a drive shaft, and even a transmission gearbox need to be installed at the power take-off port of the vehicle chassis, the power take-off port of the gearbox, the power take-off port of the transfer case, or the power take-off port of the flywheel. Then, the shaft is connected to the generator, so that the rotation of the engine drives the generator to rotate through the transmission system to provide stable electric energy outward.

[0005] However, both of the above two types of power generation systems are limited by the existing layout space of the vehicle chassis, with a low power density, and it is difficult to meet the power consumption requirements of the vehicle superstructure. Moreover, the installation is inconvenient. Therefore, the utility model provides an integrated traveling power take-off power generation system for a gearbox. Content of the Utility Model

[0007] To achieve the above objectives, the utility model is realized through the following technical solutions: An integrated traveling power take-off power generation system for a gearbox includes an engine gearbox installed at the rear end of the vehicle engine, and the engine gearbox is connected to the engine main shaft inside the vehicle body;

[0008] One end of the engine gearbox is installed with a protective housing, and a generator and a torque converter are arranged inside the protective housing;

[0009] A generator controller is configured in the middle of the chassis on one side of the vehicle body, and an output power distribution device is arranged in the middle of the chassis on the other side of the vehicle body.

[0010] As a further technical solution of the present invention, the main shafts of the generator and the torque converter are both connected to the output shaft of the engine gearbox, and the main shafts of the generator and the torque converter are on the same center line.

[0011] As a further technical solution of the present invention, it further includes a power generation system control box arranged in the engine compartment at the front side of the vehicle body for controlling the operation of the generator.

[0012] As a further technical solution of the present invention, the output power distribution device includes a storage battery and a circuit breaker. The storage battery is connected to the generator through a cable, and the engine gearbox, the circuit breaker and the output power distribution device are electrically connected.

There is no need to add additional belts, bearings or shafts, and it does not occupy the upper installation space of the chassis, has no influence on the length of the vehicle transmission system, and this power generation system is a retrofit kit, and the rest of the equipment is respectively arranged on both sides of the middle of the vehicle chassis, not restricted by the chassis installation space.

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figure 1-2 , the present utility model provides a technical solution for a transmission integrated driving power take-off power generation system: The transmission integrated driving power take-off power generation system includes an engine transmission 2 installed at the rear end of a vehicle engine. The engine transmission 2 is connected to the engine main shaft inside the vehicle body 1. One end of the engine transmission 2 is provided with a protective housing 21. A generator 22 and a torque converter 23 are arranged inside the protective housing 21. The main shafts of the generator 22 and the torque converter 23 are both connected to the output shaft of the engine transmission 2. The main shafts of the generator 22 and the torque converter 23 are on the same center line. It should be added that the generator 22 is integrated on the engine transmission 2, and the volume of the integrated engine transmission 2 is the same as that of the existing standard transmission. Thus, by integrating the generator 22 on the engine transmission 2, its power production capacity can reach 125 kW from 30 kW, which is applicable to the existing light, medium, and heavy high motor vehicle chassis. Moreover, this power generation system is a retrofit kit, which has no impact on the length of the vehicle transmission system, does not require additional belts, bearings or shafts, does not occupy the upper installation space of the chassis, is not restricted by the chassis installation space, and can provide the maximum power of electric energy for the upper installation equipment.

[0020] A generator controller 4 is configured in the middle of the chassis on one side of the vehicle body 1, and an output power distribution device 5 is arranged in the middle of the chassis on the other side of the vehicle body 1. The output power distribution device 5 includes a storage battery and a circuit breaker. The storage battery is connected to the generator 22 through a cable. The engine transmission 2, the circuit breaker and the output power distribution device 5 are electrically connected. It also includes a power generation system control box 3 configured in the engine compartment at the front side of the vehicle body 1 for controlling the operation of the generator 22. By arranging the generator controller 4 and the output power distribution device 5 on both sides of the chassis of the vehicle body 1 respectively, the equipment of the power generation system is reasonably distributed, and the original chassis space of the vehicle is reasonably utilized to the greatest extent. Thus, the problem that the traditional two major power generation systems are easily restricted by the layout space of the vehicle chassis and it is difficult to meet the upper installation power consumption requirements can be solved.

[0021] The working principle of the present utility model is as follows: The generator 22 of this design is integrated on the engine gearbox 2, and uses the generator main shaft of the vehicle body 1 to provide power. Moreover, it is integrated on the engine gearbox 2, with a small overall volume and light weight, making the volume of the engine gearbox 2 the same as that of the original standard gearbox. In this way, it does not occupy the upper installation space of the chassis, has a large power density, is not restricted by the chassis installation space, can provide the maximum power of electric energy for the upper installation equipment, and at the same time does not affect the total length of the vehicle power transmission system;

[0022] The entire power generation system is reasonably arranged on the vehicle body 1, without adding extra belts, bearings or shafts, avoiding the phenomenon of increasing the volume of the power generation system, ensuring that the overall volume of the gearbox integrated generator is small, and it can be applied to existing light, medium and heavy high-mobility chassis.

[0023] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
