Description

Technical Field

[0001] The utility model relates to the technical field of automobile components, in particular to a power generation mechanism mounted on a special vehicle. Background Art

[0002] As the cost of making and using suicide drones on the battlefield gradually decreases, ground equipment is also gradually updating its air defense strategy. Currently, the most research is on the use of directed energy weapons to shoot down drones from a distance, including microwaves, lasers, etc., but the size and power of the transmitting antenna of this type of equipment are often large (the power consumption of the whole vehicle is not less than 75kW, which meets the two working conditions of driving and parking), so a generator with a small footprint and a more flexible layout is needed to provide power to the entire air defense system.

[0003] Traditional diesel generator sets, due to their own heat dissipation, intake and exhaust, start-up control, maintenance and other requirements, have large sizes and require independent control and occupy a large space, making them difficult to install and arrange in such equipment. However, permanent magnet shaft-belt power take-off generators are small in size and flexible in arrangement, which can solve the power supply problem of this type of vehicle. Utility Model Content

The purpose of the utility model is to meet the power generation function under driving and parking conditions. The power generation generator is small in size and can be flexibly arranged without affecting the air defense equipment, meeting the sufficient power generation supply and leaving sufficient installation space for important equipment of this type of special vehicle.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special vehicle on-board power taking and power generation mechanism, including an engine flywheel housing power take-off, the engine flywheel housing power take-off is connected to a power take-off transmission shaft, the end of the power take-off transmission shaft away from the engine flywheel housing power take-off is connected to a power take-off generator, a chassis frame is provided at the bottom of the engine flywheel housing power take-off, a generator bracket is installed on the chassis frame, the power take-off generator is installed on the generator bracket, rubber shock absorbing devices are also provided around the bottom of the power take-off generator, and an upper-mounted antenna is provided above the power take-off generator.

[0006] Preferably, the power take-off generator is arranged in an inclined structure, and the inclination angle of the power take-off generator is 30°.

[0007] Preferably, the generator bracket includes a pre-installed cross beam and a support frame, two support frames are provided and are respectively installed on the pre-installed cross beam, and the four rubber shock absorbing devices are respectively provided on the two support frames.

[0008] Preferably, the power take-off transmission shaft is a ball cage type power take-off transmission shaft.

[0009] Preferably, the power take-off generator is a permanent magnet power take-off generator.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model is a power take-off and power generation mechanism mounted on a special vehicle. By arranging an engine flywheel housing power take-off, a power take-off transmission shaft, a power take-off generator, a generator bracket and a rubber shock-absorbing device, a reasonable arrangement can be made to complete the installation and power connection of a 75kW power take-off generator without increasing the vehicle length and the space occupied by the upper equipment to the greatest extent. Compared with a diesel generator set with a transmission, it can greatly save space and reduce the weight of the vehicle, leaving more size space and weight space for the upper equipment.
