Abstract

PURPOSE:To prevent mud from intruding between tires, by providing a hollow filling material between a pair of right and left tire drums so that the filling material touches the inside of the drum and the sides of a right and left tires, in the double tire for an agricultural machine. CONSTITUTION:A core material 14 is formed by fixing a rubberlike elastic body 15 on the external circumference of the cylindrical core material 14, the core material 14 is held in a pinched state by vertical walls 5a, 11a of a drums 5, 11 to which tires 6, 12 are fixed, an elastic body 15 is made to weld on the inside of walls 5a, 11a of cylinders and the core material 14 is interposed so that the central part is placed between opposed sides of the tires 6, 12. With this constitution, even if mud is about to intrude between the drums 5, 11 from the sides of the tires 6, 12, the intrusion is prevented as a filling material 13 is interposed in a gap between the drums 5, 11.

Description

[Detailed Description of the Invention] The purpose of the present invention is to prevent mud from entering between a pair of left and right tires by specifically interposing a hollow filler between the tires. be.

For agricultural machinery and other vehicles used in wet fields and muddy soil,
In order to reduce pedal pressure and increase propulsion, -71 tires are sometimes used together as a double tire. Then, during propulsion, mud gets into the drum through between the left and right tires, and this mud fills the space between the left and right drums, significantly increasing the weight and halving the purpose. In order to prevent this, it was proposed to install a packing between the left and right tires, but since tires have elasticity and deform as they rotate, the packing effect was not effective and mud could enter through the gaps. did not achieve any purpose.

In this invention, a filling material is interposed between the rigid left and right drums, and this filling material is hollow and light, and mud does not get into the drum, which is a disadvantage of the conventional method. has been completely resolved.

Next, to explain a vehicle to which this invention has been applied based on the drawings, (1) is a gear box with an axle (2) supported at the lower end, and a boss (3) attached to the pin (4) on the axle (2). ) is fixed. (5) is a drum, comprising a vertical wall (5a) and nine cylindrical walls (5b) projecting left and right from the outer periphery of the vertical wall (5a).
) is fixed to the boss (4), the left cylinder wall (
A tire (6) is attached to the outer surface of 5b).

(7) is an auxiliary axle, which is attached to the outer end of the axle (2) with a pin (8), the boss (9) is fixed with a pin, and the vertical wall (lla) of the drum (lυ) is fixed. A tire (2) is provided on the outer periphery of the cylindrical wall (11b) of this drum αυ, and the tire (6) and the tire α-gong are installed together to form a double tire.

Q3 is a filler, consisting of a cylindrical core material α and a rubber-like elastic material QQ attached to its outer periphery, and the core material αa is
It is sandwiched between the left and right vertical walls (5a) (lla), and the elastic material α0 is pressed against the inner surface of the cylindrical wall (5b) (llb), and the center part is also sandwiched between the opposing sides of each tire (6) (2). are in contact with each other. Note that the elastic material αυ in the figure is made into a striped shape to make it easy to deform, so it has a simple shape. It is better to make it slightly harder than this and form it to follow the shape of the side surface of the tire or the cylindrical surface of the drum.Furthermore, it should be formed so as to cover the side surface of the core wall and the core wall (l and vertical wall). It is better to improve the airtightness of the

Since this vehicle is constructed as described above, when it is propelled through wet fields or other muddy soil, the lower end of the tire (6) α will enter the muddy soil, and when the vehicle attempts to be propelled by its rotation, Mud tries to enter between the left and right drums (5) α0 through both sides of the tire (6) α, but the core material Q

This is prevented by close contact with X11a).

Therefore, the vehicle continues to exhibit its original performance without increasing its weight due to the mud that has entered between the drums (5) 09. In particular, in this invention, the elastic phase αQ of filling + ga3 is
Since it is in close contact with the highly rigid drum (5) αυ, the anti-mud effect is significantly higher than that of conventional tires that are pressure-bonded.

In summary, this invention provides vertical walls (5a) (lla

The tire (6) (

The elastic material αG is between the left and right vertical walls (5a) (lla) and the inner surface of the cylinder walls (5b) (llb) and the tire (6).
(Since this is a two-tire anti-mud device for double tires, which is characterized by intervening between a pair of wheels so as to make contact with the sides of the two wheels, mud will not be absorbed between the left and right drums, which have high rigidity.) It is characterized by a significantly improved anti-mud effect.
