Abstract

(57) [Summary] [Purpose] To enable a turn stopper attached to a tractor of a traveling vehicle to be used also as a muffler, and to improve its noise reduction effect. [Structure] A turn stopper 5 attached to a tractor of a traveling vehicle is attached to a pair of left and right hollow side portions 11, 11 on which stoppers 12 are attached to both left and right sides of a hollow main body portion 10.
The main body part 10 has a hollow shape having a lower hollow chamber 20, an upper right hollow chamber 21, and an upper left hollow chamber 22, and a main inlet 24 for engine exhaust gas opening into the lower hollow chamber 20, A first hole 26 that communicates the lower hollow chamber 20 and the upper right hollow chamber 21 , a second hole 27 that communicates the upper right hollow chamber 21 and the upper left hollow chamber 22 , and the upper left hollow chamber 22 and one side 11 . This muffler also serves as a turn stopper for a running vehicle, which has a hole communicating with a hollow chamber 30 and has an exhaust pipe 32 attached to the upper part of one side 11 thereof. [Effects] The turn stopper 5 can also be used as a muffler, and the engine exhaust gas expands and contracts four times when flowing through each hollow part of the turn stopper 5, resulting in an excellent noise reduction effect.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a turn stopper for a moving vehicle that swingably connects a tractor and a wagon. Regarding dual-purpose mufflers.

0002

[Conventional technology]

As shown in Figures 1 and 2, a wagon 2 is mounted on a tractor 1 and is automatically swung horizontally around a vertical shaft 3. Currently, there is a known running vehicle connected to the vehicle, and the wagon 2 is a bottom dump type with an opening/closing bottom. It becomes. Such a traveling vehicle steers the wheels 4 of the tractor 1 and rotates around the vertical axis 3 when turning. Keep in mind that tractor 1 and wagon 2 should bend horizontally, and avoid making too large a bend. When this happens, tractor 1 is pushed by wagon 2, a so-called jackknife phenomenon occurs, resulting in a dangerous situation. It's dangerous. For this purpose, a turn stopper 5 is provided on the tractor 1 to restrict bending. .

0003

[Problem that the idea aims to solve]

Since the turn stopper 5 supports the heavy wagon 2, it has a large weight. The structure is expensive, requires a large installation space, and the jack-knight Merely having a function to prevent the phenomenon of failure is useless.

0004 Therefore, the present invention has been developed to provide a turn stop for running vehicles that can solve the above-mentioned problems. The purpose is to provide a muffler that can be used for both public and private vehicles.

[Means to solve the problem]

A turn stopper 5 attached to a tractor of a traveling vehicle is connected to a hollow body part 1. A pair of left and right hollow-shaped side parts 11, 11 to which stoppers 12 are attached on both the left and right sides of the The main body part 10 has a lower hollow chamber 20, an upper right hollow chamber 21, and an upper left hollow chamber. The engine exhaust has a hollow shape with a hollow chamber 22 and opens into the lower hollow chamber 20. A first hole 26 that communicates the main gas inlet 24 with the lower hollow chamber 20 and the upper right hollow chamber 21. and a second hole 27 that communicates the upper right hollow chamber 21 and the upper left hollow chamber 22, and the upper left hollow chamber. 22 and the hollow chamber 30 of one side 11 are formed, and the one side 11 A muffler that doubles as a turn stopper for a running vehicle with an exhaust pipe 32 attached to the top of the muffler.

[Effect]

The turn stopper 5 can also be used as a muffler, and the engine exhaust gas can be When flowing through each hollow part of the stopper 5, expansion and contraction are repeated four times. This provides an excellent sound deadening effect.

【Example】

As shown in FIGS. 3 to 5, the turn stopper has a hollow vertically elongated main body 10. and a pair of hollow vertically elongated side parts 11, 11 provided on both left and right sides of the main body part 10. and a stopper 12 attached to the side surface of each side part 11, and the main body part 10 has an approximately H-shape. The front vertical plate 13, the rear vertical plate 14, the lower plate 15, the upper plate 16, and the left and right side plates 17, 17 It has a vertically elongated hollow shape, and a diaphragm 18 is placed between the upper and lower intermediate parts of the front and rear vertical plates 13 and 14. At the same time, a medial diaphragm 19 is installed across the diaphragm 18 and the upper plate 16. A hollow chamber 20, an upper right hollow chamber 21, and an upper left hollow chamber 22 are partitioned.

[0006] A pair of cylindrical bodies 23, 23 are attached to the lower part of the front vertical plate 13 to form the lower hollow chamber 2. 0 constitutes a pair of main inlets 24, 24 for introducing engine exhaust gas into the lower hollow chamber. The engine exhaust gas flowing into the diaphragm 20 passes through the first hole 25 formed in the diaphragm 18 to the upper right middle part. The engine exhaust gas that has flowed into the empty chamber 21 and the upper right hollow chamber 21 passes through the medial partition plate 19. It flows into the upper right hollow chamber 22 from the second hole 27 of 8, 29 into the hollow chamber 30 of one side 11, and the upper plate of that one side 11. It is discharged from the exhaust pipe 32 attached to 31, and the turn stopper also serves as a muffler. Ru. In other words, the side part 11 is formed by the upper plate 31, the front and rear vertical plates 33, 34, the lower plate 35, and the side plates 36. A hollow chamber 30 is formed with the side plate 17, and a diagonal portion 36a of the side plate 36 is formed. A stopper 12 is attached, and an opening 37 is formed near the side plate 36 of the front vertical plate 33. The stopper 12 is attached by inserting the hand through the opening 37.

[0007]

[Effect of the idea]

The turn stopper 5 can also be used as a muffler, and the engine exhaust gas can be When flowing through each hollow part of the stopper 5, expansion and contraction are repeated four times. This provides an excellent sound deadening effect.
