Definitions
- the present invention relates to a tread arrangement structure of a tire crawler mounted on a vehicle and used for traveling, and particularly to a tread structure in which generation of vibration with high traction force is reduced.
- a tread is arranged on a surface and a pitch of the tread is increased to increase the traction force. Attempts have been made to raise
- the present invention will be described by taking a crawler tread as an example.
- the crawler is divided into left and right areas in the width direction, and treads are separately arranged on the left and right surfaces.
- Increasing the tread pitch increases traction.
- the vibration increases and the durability of the tread deteriorates.
- the present invention relates to a tread arrangement in which a traction force is required on the ground and vibrations are less likely to occur during traveling. It provides a tread arrangement with traction and low vibration, even in different situations.
- the main feature of the present invention is a tread structure in which a ground contact surface is bisected in the left-right width direction with respect to a traveling direction and treads are arranged on respective surfaces, and the tread structures are adjacent to each other.
- High traction force characterized by interweaving the long pitch, middle pitch and short pitch at the tread interval, arranging the left and right treads asymmetrically, and making the total area of the treads of the left and right treads approximately equal
- a low vibration tread structure Provides a low vibration tread structure.
- the present invention has the tread arrangement structure as described above, and makes it possible to provide a vehicle with high traction force and low vibration.
- FIG. 1 is an external surface view of a long pitch crawler.
- FIG. 2 is an outer surface view of a crawler with a medium pitch.
- FIG. 3 is an outer surface view of a crawler with a short pitch.
- FIG. 4 is an outer surface view of a crawler having a tread according to the present invention.
- FIG. 5 is a perspective view of a tread-arranged tire according to the present invention.
- the present invention is a tread structure in which a ground contact surface is bisected in the left-right width direction with respect to the traveling direction, and treads are arranged on each surface, and the distance between adjacent treads on each surface is different.
- the present invention relates to an arrangement in which the right and left treads are arranged asymmetrically, and the total area of the treads of the left and right treads is substantially equal.
- the present invention also achieves a predetermined effect by selecting only the following three types (three conditions) of treads of various types of tread pitches and arranging them regularly (asymmetrically). It's a trick.
- the long pitch tread is configured to mainly achieve a large traction force, and almost no mud clogging occurs between the treads, and a predetermined traction force is provided.
- a predetermined traction force is provided for medium pitch treads, moderate traction is exerted and vibration is not so large because the distance between treads is narrower than for long pitches.
- the short pitch tread has a structure in which mud is clogged and traction is not enough, but there is no problem in terms of vibration.
- the present invention provides a desired effect by combining these various pitch treads. Things.
- the tread is formed by interweaving the treads of the long pitch, the medium pitch, and the short pitch as described above, and the treads are arranged asymmetrically in the left and right directions. Make the total area of the ground approximately equal.
- the left and right treads are arranged asymmetrically in order to eliminate such a result.
- the total area of the installation surfaces of the treads arranged on the left and right was balanced to be almost equal.
- the treads arranged on the left and right sides are not substantially overlapped in a side view when cut at the center in the width direction!
- a tread arrangement having a medium pitch and a short pitch with a long pitch interposed therebetween is preferable in terms of balance.
- the other tread is preferably configured to have an opposite pitch arrangement.
- the short pitch refers to a configuration in which there is substantially no gap between the pitches.
- the short pitch can be combined with one large tread.
- the shape of the tread alone is arbitrary.
- Figure 1 and Figure 3 show that the tread is divided into two parts in the width direction, (L, Fig. 1), medium pitch (L, Fig. 2), short pitch (L, Fig. 3) only treads 1, 1, 1
- FIG. 3 is an outer plan view of the crawler 10 constituted by 1 2 3 1 2 3.
- tread 1, 1, 1 tread 1, 1, 1
- 1 2 3 is inclined about 30 degrees from the left and right width direction, and the distance L between tread centers is 225 m
- treads 1 and 1 are close to each other, clogging of mud, stones and the like during this time is severe.
- FIG. 4 shows the tread arrangement, the medium pitch and the short pitch with a long pitch interposed therebetween, where the treads arranged on the left and right surfaces do not overlap in a side view (when cut at the center in the width direction).
- An example is shown in which the configuration including the tread arrangement described above and the tread arrangement in which the tread arrangement arranged in the left-right width direction forms an inverse pitch arrangement is embodied on the outer surface of the crawler.
- treads 1 and 1 exhibit great traction, tread 1, 1 is not so good tread 1, 1 does not exert great traction.
- the tread is arranged with respect to the pitch L of the left tread.
- the rolling wheels that roll on the inner peripheral surfaces of the treads on both right sides achieve almost the same vibration condition as a whole, where there is no large drop.
- the crawler is designed so that there is no twist or skew.
- the long, medium, and short pitches do not necessarily need to be arranged in the order shown in the drawing, and the left and right pitches can be balanced, needless to say! /.
- FIG. 5 shows an example in which the tread arrangement shown in FIG. 4 is applied to a tractor tire, and has the same effect as that described with reference to FIG.
- the present invention can provide a tread arrangement excellent not only in vibration but also in traction force, and is applicable not only to a crawler but also to a tread of a tire that rolls on a ground contact surface. And its utilization is extremely high.
