トモーション用長孔を介して連結するようにした手段が
従来提案されている。Conventionally, in this type of cab tilt device, a hydraulic cylinder device is interposed between the chassis and the cab that is pivotally supported by the chassis, and pressure oil is supplied and discharged to and from two of the four hydraulic cylinders to control the tilting of the cab. I am trying to make it do this, but when not tilting,
In other words, when the vehicle is running, the supply and discharge of the pressure oil is cut off, causing the hydraulic cylinder device to enter an oil lock state, and the cab is fixed to the chassis, worsening ride comfort.This allows the cab to move relative to the chassis. The so-called Lost Morph 3-F mechanism, which is divided into two parts, is used in various ways, especially when the end of the rotor of a hydraulic cylinder device with mechanical lost motion and the lower edge of the cab are connected through a long hole for lost motion. Conventionally, means for coupling have been proposed.

らす欠点があつ/こ。However, with such a cost motion mechanism, although it is possible to improve riding comfort by allowing the cab to move up and down through the long lost motion hole during driving, when the cab is tilted, the cab heavy knob B does not tilt the cab. When it crosses the center, the cap force that had been pushed up by the tip of the rod connected to it at the upper end of the long hole for lost motion (1" However, there are drawbacks to the sudden overtilting of the vehicle by an amount corresponding to its freedom, as well as the negative impact of impact on various parts of the vehicle body, as well as the danger to the operator.

安全を期することができる。In order to achieve the configuration described above, the cab lock mechanism (not shown) is divided by ψ() and the pressure oil is supplied to the hydraulic cylinder device (3) by λ.
As shown in Fig. 1, when the piston rod (4.) Q, 1 and the connecting member (5) are pushed up together, the arcuate top part is attached to the lower edge of the cab. Insert the pin (5b) 1/2 inch above the elongated hole (6b) of the bracket (6).
Position it at RA and start tilting the cab (2),
In this process, the spherical locking part (4a) at the tip of the rod passes through the wide passage opening (6d) at the bottom of the bracket (6).
1] The narrow recessed retaining portion (6e) and the rod diameter reducing portion (4b) are placed in opposing positions. In this state, the tilt center ('1') 't: When the tilting of the cab (2) at the center progresses and reaches a predetermined tilt angle, the piston rod on the cab (2) side extends in the direction as shown in Figure 1. By changing the inclination angle with respect to It is directly connected to the piston rod (4), and further relative movement of the bracket (6) with respect to the piston rod (4) is prevented.Therefore, even if the center of gravity of the cab (2) exceeds the tilt center point (1゛). Even if there is a sudden excessive tilting of the cab (2), the shock to the bracket (6) that may occur can be eliminated, and the cab tilt operation can be performed safely.
