It is called. ), beam 11, chassis 5, chassis 5
ram cylinders 13 arranged on both sides of the
An axle swinging mechanism (hereinafter referred to as an axle swinging device) is formed from a pin 12 that connects the beam 11 and the chassis 5.
This axle rocking allows the rocking axle 7 to swing during driving (especially when driving on rough terrain), so that all four tires 9 on the front, rear, left and right sides are in contact with the ground. Also, during work (during excavation, crane work, suspended load traveling work, etc.), the swing axle 7 is fixed to ensure the stability of the lower traveling body 3.

The beam 11 mentioned above is a separate part from the swing axle 7,
Although the case where the beam 11 and the swing axle 7 are fixed to the swing axle 7 with bolts and swing together has been described, in the case of a small machine, the beam 11 and the swing axle 7 may be manufactured as one piece. Therefore, in such a case, the chassis 5 and the swing axle 7 are directly connected by the pin 12 without using the beam 11.

An example of the conventional axle rocking device described above is shown in FIGS. 7 and 8. Brackets 22 are attached to both sides of the chassis 5, and the brackets 2 are attached to both ends of the beam 11 to which the swing axle 7 is fixed with bolts or the like.
Brackets 23 were attached corresponding to 2, and these brackets 22 and 23 were connected to each other by pins 17 and 18 at both the upper and lower ends of the hydraulic ram cylinder 16, and the oil chambers of the hydraulic ram cylinders 16 on both sides were communicated with each other. It is something. When driving,
The oil chambers of the hydraulic ram cylinders 16 on both sides are communicated so that the swing axle 7 and the beam 11 can swing relative to the chassis 5, and the communication between the oil chambers of the hydraulic ram cylinders 16 on both sides is cut off during work. However, even if the ram rod 21' receives an external force, it is not pushed into the hydraulic ram cylinder 16 by the generated hydraulic pressure, and the swing axle 7 and beam 11 are prevented from swinging relative to the chassis 5 by being balanced with the external force. This is to keep it in a fixed state. However, in this conventional axle rocking device, the upper and lower ends of the hydraulic ram cylinder 16 are rotatably attached to the bracket 22 of the chassis 5 and the bracket 23 of the beam 11 by pins 17 and 18, so it is difficult to understand the mechanism. In general, only axial force acts on the ram rod 21' of the hydraulic ram cylinder 16, and no lateral load is generated, so there is no oil leakage, which is ideal.
The disadvantage is that there are many parts such as 23, the number of man-hours during manufacturing is high, and the cost is high.

Therefore, an axle rocking device with fewer parts was developed. This axle rocking device is shown in FIGS. 9 to 11.
As shown in the figure, the main body of the hydraulic ram cylinder 15 is fixed to the chassis 5 with bolts 14, and the tip 24 of the ram rod 21'' of the hydraulic ram cylinder 15 is fixed to the chassis 5 with bolts 14.
is formed into a spherical convex shape, and on the other hand, a spherical concave portion 25 having a radius of curvature larger than the radius of curvature of the spherical convex portion 24 is formed at a location where the ram rod 21'' of the hydraulic ram cylinder 15 of the beam 11 comes into contact.
A spherical convex portion 24 is brought into contact with the spherical convex portion 24. However, in this axle swinging device, the hydraulic ram cylinder 15 is fixed to the chassis 5, and the spherical convex portion 24 of the ram rod 21'' of the hydraulic ram cylinder 15 is brought into contact with the spherical concave portion 25 of the beam 11. , the number of parts is reduced compared to an axle swinging device in which both ends of the hydraulic ram cylinder 16 are attached with pins, but when the swinging axle 7 and beam 11 swing, a lateral load is applied to the ram rod 21'' of the hydraulic ram cylinder 15. It takes. That is, as shown in FIG. 11, when the swing axle 7 is horizontal, the beam 11 is in a horizontal state as shown by the two-dot chain line, and the spherical convex portion 24 of the ram rod 21'' is in the spherical concave portion 2 of the beam 11.
5, and a load is applied to the ram rod 21'' in the direction of the central axis O of the ram rod 21'' as shown by arrow A. However, when the swing axle 7 swings, the beam will move as shown by the solid line. In the tilted state, the spherical convex portion 24 of the ram rod 21'' comes into contact with a point b shifted from the center point a of the spherical concave portion 25 of the beam 11,
A diagonal load as shown by arrow B is applied to the ram rod 21'' from point b toward the spherical center of the spherical convex portion 24. This has the disadvantage of causing oil leakage and enlargement of the hydraulic ram cylinder 15. Also, Ramrod 21″
It also has the disadvantage that the number of processing steps increases because it is necessary to form the tip into a spherical convex shape.

The axle rocking device of the present invention in this embodiment is as follows:
With the above configuration, when the swing axle 7 is horizontal as shown in FIG. Beam 1 at
1, and a load is applied to the ram rod 21 in the same direction as the axial direction of the ram rod 21, as shown by arrow A. When the swing axle 7 swings, the beam 11 is in a tilted state as shown by the solid line, and the lower end plane of the ram rod 21 is offset from the convex curved surface portion 26 of the beam 11 at a location deviated from the central axis O of the ram rod 21. Point deviated from center point a′
b', but the ram rod 21 has the swing axle 7
As in the horizontal state, Ramrod 21 as shown by arrow C
A load is applied in the same direction as the axial direction. For this reason, only a slight eccentric load is applied to the hydraulic ram cylinder 13 based on the amount of eccentricity between points a' and b', which has the drawback of receiving a large lateral load and causing oil leakage, unlike the conventional case. can be improved.
Further, there is no need to perform spherical bending on the ram rod 21 of the hydraulic ram cylinder 13. Furthermore, since the hydraulic ram cylinder 13 is fixed to the chassis 5, the number of parts can be reduced compared to an axle swinging device in which the hydraulic ram cylinder 16 is attached with a pin.

The basic operation of the axle rocking device is to communicate the oil chambers 20 of the plurality of hydraulic ram cylinders 13 with each other during traveling, to make the rocking axle 7 swingable, and to operate these hydraulic ram cylinders during work. The communication between the oil chambers 20 of 13 is cut off, and the swing axle 7
The operation to fix the state naturally works.

As is clear from the above embodiments, the axle swinging device of the wheeled hydraulic excavator of the present invention has a ram cylinder whose ram lower end surface has a planar shape fixed to both sides of the chassis, and corresponds to the ram lower end surface. A convex curved surface is provided on the swinging axle or beam at a position where the swinging axle is moved, and the ram lower end surface and the convex curved surface are in contact with each other. A lateral load is applied to the cylinder only to an extent that can be ignored in practical terms. Further, since the portion that contacts the convex curved surface portion of the ram cylinder is simply made flat, spherical processing is not necessary. Furthermore, since the ram cylinder is fixed to the chassis, the number of parts can be reduced compared to an axle swinging device in which the ram cylinder is attached to the chassis with a pin.
