Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a track plate for the undercarriage of a tracked vehicle.

PRIOR ART As shown in Fig. 1, this type of conventional track shoe a transitions from a state where it is wrapped around an idle wheel or a starting wheel to a steady state (wrapping angle Θ→O).
A lap part b was provided to prevent damage caused by rocks being sandwiched in between.

However, when the wrap angle Θ becomes large, the wrap portion 2 becomes longer and weaker in strength, resulting in an increase in weight, and roll forming is difficult, resulting in poor productivity.

Purpose of the invention The purpose of the invention is to prevent rocks from being pinched between adjacent tracks when the track transitions to a state where it wraps around the idler or starting wheel, and to facilitate roll forming by eliminating the need for a lap part. The aim is to improve productivity.

Structure of the invention In the present invention, the front and rear ends of the track body 5 in the running direction are made thicker than other parts, and the inner surface 10 of the track body 5 is attached to the end of the thick part 6 on the front end side. A slope 8 is formed that slopes at an angle θ ₁ toward the rear of the outer surface with respect to the front end surface 11 that is perpendicular to the front end surface 11 . A slope 9 is formed that slopes at an angle θ ₂ toward the front of the outer surface with respect to the rear end surface 12 that is perpendicular to the rear end surface 12. This is to eliminate the possibility of rocks getting stuck.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIG.

In the drawings, numeral 1 is a track board, and numeral 2 is a link.

The crawler plates 1 are fixed to links 2 with bolts, and adjacent links 2 are connected to each other by pins 3 and bushes (not shown), forming a crawler track 4.

The track shoes 1 are equipped with a track board main body 5, and the track board main body 5
The front and rear end portions in the running direction are made thicker than the other portions, and slopes 8 and 9 are formed at the ends of both thick portions 6 and 7. The front slope 8 is inclined at an angle θ ₁ toward the rear of the outer surface with respect to the front end surface 11 that is perpendicular to the inner surface 10 of the track body 5, and the rear slope 9 is inclined with respect to the inner surface 10 of the track body 5. The outer surface portion is inclined at an angle θ ₂ toward the front side with respect to the rear end surface 12 forming a right angle.

Therefore, when the crawler belt 4 transitions from the state where it is wrapped around the idler wheel or the starting wheel to the steady state (wrapping angle Θ→O), the rear end surface 12 of the front track shoe 1 and the front end surface of the rear track shoe 1 Although it is close to 11, both slopes 9 and 8
Because of this, there is no rock entrapment.

Effects of the invention Since the present invention is as described above, it is possible to prevent rocks from being pinched by adjacent track plates 1 when the crawler track 4 transitions from the state where it is wrapped around the idle wheel or the starting wheel to the steady state. Since the conventional wrap part is not required, roll forming becomes easier and productivity is improved.

Claims (1)

[Scope of utility model registration request] The front and rear ends of the track body 5 in the running direction are made thicker than other parts, and a front end surface 11 is provided at the end of the thick wall part 6 on the front end side, making a right angle to the inner surface 10 of the track body 5. A slope 8 is formed that slopes at an angle θ ₁ toward the rear of the outer surface, and a rear end surface 12 that is perpendicular to the inner surface 10 of the track body 5 is formed at the end of the thick wall portion 7 on the rear end side. A track shoe characterized by forming a slope 9 inclined toward the front side of the outer surface portion over an angle θ ₂ .
