Description

[Detailed description of the invention] Industrial field of application This invention relates to improvement of tracks used in tracked vehicles.

BACKGROUND OF THE INVENTION Conventional crawlers for tracked vehicles, such as those shown in FIGS. 6 and 3, are known. The above-mentioned crawler track is constructed by inserting pins C into both ends of blocks B having grouser A protruding from the ground surface, and connecting the ends of these pins C with end connectors d, thereby connecting each block B in an endless manner. , a center guide e is provided protruding from the surface opposite to the grounding side.

Problems that the invention aims to solve However, once the conventional crawler tracks are installed on a vehicle, the grouser a of the same shape remains the same even when driving conditions change.
The running performance may deteriorate depending on the running conditions, and if grouter a wears out, the entire block b must be replaced, which is uneconomical. .

This invention was made for the purpose of improving the above-mentioned problems.

Means and action for solving the problem: A grouser member suitable for running conditions can be selected from among multiple types of grouser members with different grouser shapes prepared in advance and can be attached and detached to the ground plane of the blocks connected in an endless manner by condo connectors. A tracked vehicle track that is installed on a tracked vehicle to ensure stable running performance even under changing running conditions.

Embodiment One embodiment of this invention will be described in detail with reference to the drawings. In the figure, 1 is the body of a tracked vehicle, and an endless track body 4 is wound between an idler 2 and a sprocket 3 provided at the front and rear. has been done. The main body 4 is made into an endless shape by connecting both ends of pins 6 fitted to both ends of a large number of blocks 5 with an end connector 7, and a center guide 8 is provided protruding from the surface opposite to the ground side of the blocks 5. has been done. As shown in FIG. 3, the block 5 is a flat plate with cylindrical bulges at both ends, and a pin 6 is inserted through the bulges 5a. 5a
A guide rail 9 is provided protrudingly located between them. The guide rails 9 form grooves 9b on both sides of the flat plate 9a, into which a rail member 10a having a substantially C-shaped cross section and protruding from one side of the grouser member 10 can be inserted and removed. In this structure, an elastic tongue-shaped locking pawl 10b is provided protruding from one end side of the rail member 10a.
Also, a stopper 5b is formed at one end of the block 5, and a locking hole 5c is formed at the other end, so that the rail member 10a of the grouser member 10 can be
When the block 5 is inserted from the side along the guide rail 9 until the end of the block 5 contacts the stopper 5b, the locking pawl 10b falls into the locking hole 5c, and the tip of the locking pawl 10b is locked. It is designed to be locked to the opening edge of the hole 5c as shown in FIG.

On the other hand, the grouser member 10 is a substantially square plate having the rail member 10a on one side and a grouser 10c protruding from the other side, and a plurality of types of grouser 10c with different shapes are prepared. It can be replaced depending on the purpose.

That is, the one shown in Figure 5 A is for general driving, B in the same figure is for rocky ground, C in the same figure is for soft ground, D in the figure is for driving on paved roads with Grouser 10c as an elastic plate, and E in the same figure is for testing. It is in use.

By selecting these pre-prepared grouser members 10 according to running conditions and attaching them to each block 5 of the crawler track body 4, stable running performance can always be obtained even when running conditions change.

Note that in order to remove the grouser member 10 attached to each block 5, open the locking hole 5 from the inside of the block 5.
The tip of the locking pawl 10b can be removed by inserting a tool or the like into the stopper c and pressing the tip of the locking pawl 10b downward, and then pulling it out in the direction opposite to the stopper 5b.

Effects of the invention Since this invention has been described in detail above, grouser members 1 with different grouser shapes prepared in advance
0 according to the running conditions and attaching it to the ground surface of the block 5 that constitutes the crawler track body 4.
Stable driving performance can always be obtained even when driving conditions change.

Further, since the grouser does not protrude from the cylindrical bulges 5a formed at both ends of the block 5, the leg length of the grouser 10c can be increased without increasing the thickness of the grouser member 10 attached to the block 5. 10 can be provided lightweight and inexpensively.

This prevents costs from increasing even if multiple types of grouser members 10 are prepared according to the running conditions, and even if they are attached to each block, the weight of the track body 1 increases and the running performance deteriorates. There is no risk that it will decline.

Moreover, while using it for a long time, Grocer 10c
Even if there is friction, the grouser member 10 can be used simply by replacing it with a new one, which is economical, and when a grouser shape suitable for the geology is determined through experiments, etc., the grouser member 10 can be used by simply replacing the grouser member 10. As a result, you will be able to conduct experiments more efficiently.
