A linkage water guiding device for tracked vehicles

Abstract

The present invention discloses a novel linkage water-guiding device for tracked vehicles, and provides a function for switching water-guiding blades between different working environments on land and water. In the land driving state, the oil cylinder piston can be retracted, and then the linkage water-guiding mechanism can be retracted to increase the distance between the water-guiding blades and the track, prevent collision and soil splashing after the track jumps, and greatly improve the service life and reliability of the water-guiding device. Provide a device that can adaptively adjust the position of the blades under different underwater working conditions. In the underwater driving state, different winds and waves and driving speeds require different angles between the water-guiding blades and the horizontal line. The present invention can adjust it by controlling the oil cylinder to achieve underwater propulsion assistance at the optimal water-guiding angle, and can also be combined with an intelligent system to control the oil cylinder to achieve full-automatic adjustment; the water-guiding blades can be replaced individually when accidentally damaged, and have the advantages of simple device structure, low failure rate, high reliability, and good maintainability.

Description

Technical Field

[0001] The invention belongs to the technical field of amphibious tracked vehicles and relates to a linkage water guiding device for a tracked vehicle. Background Art

[0002] When a tracked armored vehicle is traveling on water, it uses the track paddling as a source of propulsion. The structural form of its water guide device has a great influence on the maximum speed and steering performance of the vehicle on water. The closer the blades of the water guide device are to the rotating track, the more obvious its ability to guide the water flow stirred by the track is. During the driving process on land, due to the shape and installation position of the water guide device, when the vehicle is driving at high speed or turning on soft roads such as beaches, the loosening and jumping of the track may touch the blades of the water guide device, causing damage. Therefore, it is required that the water guide blades and the track maintain a certain safe distance. The existing water guide device is a metal sheet metal welding structure, and the water guide blades are welded to the external frame as a whole. When the vehicle's guide wheel is adjusted, the distance between the track and the blade changes, and the position of the blade cannot be adjusted accordingly. When the blade is damaged, it cannot be replaced separately. Therefore, it is the main goal of this field to provide a new water guide device that can adjust and replace the position of the water guide blade and improve the anti-destruction ability of the water guide blade. Summary of the invention

[0003] The purpose of the present invention is to provide a linkage water guiding device for a tracked vehicle to solve the above-mentioned problems.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A linkage water-guiding device for a tracked vehicle comprises a support frame, a power mechanism and a linkage water-guiding mechanism are arranged on the lower side of the support frame, wherein the linkage water-guiding mechanism comprises N water-guiding blades, both sides of the water-guiding blades are respectively hinged to the left side plate and the right side plate of the support frame, and the tail is respectively hinged with N-1 linkage rods, wherein N is a natural number greater than 2.

[0006] Furthermore, the support frame includes a support plate, a left side plate and a right side plate, the support frame is connected to the vehicle body by bolts passing through the light holes of the support plate, and the left side plate and the right side plate are symmetrically installed on the lower side of the support plate.

[0007] Furthermore, the power mechanism includes a cylinder support, a power cylinder, a guide block, a guide rod, a horizontal push rod and a vertical push rod.

[0008] The cylinder support is fixed on the lower side of the support plate, one end of the power cylinder is hinged to the axial hole of the cylinder support, and the other end is hinged to the axial hole of the guide rod, and the light rod part of the guide rod is inserted into the guide hole of the guide block; the guide block is fixed on the lower side of the support plate to ensure that the guide rod can move linearly; the horizontal push rod is positioned in coordination with the axial hole at the other end of the guide rod, and one end of the two vertical push rods are respectively hinged to the left and right sides of the horizontal push rod.

[0009] Furthermore, the vertical push rod also includes a sleeve rod and a threaded rod; the threaded rod cooperates with the sleeve rod through threads, and both ends of the sleeve rod and the threaded rod use joint bearings.

[0010] Furthermore, the linkage water guiding mechanism further includes water guiding blades I, water guiding blades II, water guiding blades III, water guiding blades IV, linkage rods I, linkage rods II and linkage rods III;

[0011] The tail of water guide blade I is hinged to two vertical push rods, and the two sides are hinged to the left and right plates respectively; the two sides of water guide blade II, water guide blade III and water guide blade IV are hinged to the left and right plates respectively, and the tail is hinged with three linkage rods I, linkage rod II and linkage rod III respectively.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0013] 1. Provide a function that can switch the water-guiding blades between different working environments on land and water. When driving on land, the cylinder piston can be retracted, and then the linked water-guiding mechanism can be retracted to increase the distance between the water-guiding blades and the track, prevent collision and soil splashing after the track jumps, and greatly improve the service life and reliability of the water-guiding device.

[0014] 2. Provide a device that can adaptively adjust the blade position under different underwater working conditions. When driving underwater, different wind and waves and driving speeds require different angles between the water-guiding blades and the horizontal line. The present invention can adjust them by controlling the oil cylinder to achieve underwater propulsion assistance at the optimal water-guiding angle, and can also combine with the intelligent system to control the oil cylinder to achieve fully automatic adjustment.

[0015] 3. The water guide blades can be replaced individually when accidentally damaged, and have the advantages of simple device structure, low failure rate, high reliability and good maintainability. BRIEF DESCRIPTION OF THE DRAWINGS
