Description

Technical Field

[0001] The invention relates to the technical field of agricultural machinery, and in particular to a truck chassis structure with time-sharing six-wheel drive on-road and off-road functions. Background Art

[0002] Agricultural trucks are favored by rural users for their strong climbing ability, large load capacity, low consumption and low cost, making them widely used in rural areas. Agricultural trucks are mainly composed of a frame, a box mounted on the frame, and a power unit and power transmission device mounted on the frame. The engine as a power unit and the clutch and gearbox as a power transmission device are generally located in the front of the box. The engine crankshaft is arranged longitudinally along the agricultural tricycle. The output power passes through the clutch, gearbox, and drive shaft to the differential, and then drives the left and right rear wheels of the agricultural tricycle through the left and right half shafts. At present, the use function of agricultural trucks is single and is limited to being used as a means of transportation.

[0003] However, when driving on mountainous areas or rugged roads, the connection between the moving wheels and the chassis is fixed, which makes it easy for the agricultural truck to overturn, or the slope is too steep, causing the driving wheels to be suspended in the air and lose grip, making the vehicle unable to move. Summary of the invention

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Reference Figure 1 to Figure 2As shown, the present invention adopts the following technical scheme: a truck chassis structure with time-sharing six-wheel drive road and off-road functions, including a chassis with moving wheels, a drive assembly and a connecting piece, the chassis consists of a front chassis 1 and a rear chassis 2, the driver is installed on the front chassis 1, the connecting piece is installed between the front chassis 1 and the rear chassis 2, the connecting piece consists of a connecting plate 1 3, a connecting plate 2 4, a connecting shaft 5, a connecting block 1 6 and a connecting block 2 7, the connecting plate 1 3 is installed on the front chassis 1, the connecting plate 2 4 is installed on the rear chassis 2, and one end of the connecting shaft 5 is rotated The connecting plate 1 is movably installed on the connecting plate 3, the other end of the connecting shaft 5 is installed on the connecting plate 2 4, the connecting block 1 is rotatably installed on the connecting shaft 5, the connecting block 2 7 is installed on the connecting shaft 5, a hydraulic cylinder 8 is movably installed on the connecting block 2 7, and the free end of the hydraulic cylinder 8 is movably installed on the connecting block 6, the connecting plate 2 4 is provided with a limiting bolt 9, the connecting plate 2 4 is provided with a fixing plate 10, a reinforcing plate 11 is installed on the end of the fixing plate 10 away from the connecting plate 2 4, and the end of the reinforcing plate 11 away from the fixing plate 10 is installed on the connecting plate 2 4.

[0021] The connecting block 1 6 is located above the connecting block 2 7 .

[0022] The hydraulic cylinder 8 is a double-bar hydraulic cylinder 8 .

[0023] The driving component is used to adjust the driving mode, and the driving modes are divided into two-wheel drive, four-wheel drive and six-wheel drive.

[0024] Steps:

[0025] When driving on a bumpy road, the electromagnetic valve of the hydraulic cylinder 8 is adjusted and controlled (i.e., the free end of the hydraulic cylinder 8 is free of pressure and can be freely extended and retracted), and the moving wheel on the front chassis 1 is automatically adjusted along the shape of the bumpy road due to the setting of the connecting piece (specifically, when the free end of the hydraulic cylinder 8 is free of pressure, when encountering a bumpy road, the connecting block 6 follows the swing of the front chassis), so that the moving wheel on the front chassis 1 is always in contact with the ground, thereby avoiding the situation where the driving wheel is suspended in the air and loses grip due to excessive slope, resulting in the vehicle being unable to move;

[0026] Since one end of the connecting shaft 5 is movably connected and installed on the connecting plate 3, the rear end chassis 2 maintains its original state (the state of traveling on a bumpy road). The driving mode is adjusted by adjusting the driving mode so that the moving wheels on the rear end chassis 2 and the moving wheels on the end chassis are always in contact with the ground, thereby avoiding the situation where the driving wheels are suspended in the air and lose grip due to excessive slope, resulting in the vehicle being unable to move.

[0027] When traveling on a flat road, the electromagnetic valve of the hydraulic cylinder 8 is reversely adjusted (i.e. the hydraulic cylinder 8 is full of pressure, and the free end cannot be freely extended or retracted), so that the front chassis 1 and the rear chassis 2 remain level and do not shake, thereby ensuring stability on a flat road;

[0028] By providing the limiting bolt 9, it is avoided that the angle between the connecting block 1 6 and the connecting block 2 7 is adjusted too large, so that the center of gravity of the vehicle is shifted and overturned.

[0029] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
