いた。 In the driver's cab of a truck that can tilt forward, the chassis is elastically supported by a spring suspension system,
It is known that a hydraulic cylinder for forward tilting is provided between the driver's cab and the chassis. In such a structure, when the driver's cab is in the normal riding position, the connection between the piston rod of the hydraulic cylinder and the driver's cab is required to allow relative rocking between the driver's cab and the chassis due to the suspension system. It is necessary to provide a mechanism to absorb relative vibration. Therefore, this mechanism must be structured to allow rocking under normal conditions and to lift the driver's cab when the driver's cab is tilted forward. Conventionally, bypass piping was provided to communicate the front and rear chambers of the piston of the hydraulic cylinder, or a complicated mechanical connection device was used.

い。 In the present invention, one end of the swinging member 13 is pivotally connected to the hinge bracket 6 by a first pin 14, and the other end is connected to a fork 12 provided at the tip of the piston rod 11 by a second pin 15. do. Further, the hinge bracket 6 is formed with an engaging portion 16 with which the second pin 15 engages when the piston rod 11 is extended. Note that the engaging portion 16 is an arc-shaped notch centered on the first pin 14 in the drawing. This notch may be a groove if necessary.

するのである。 Since the present invention has the above-mentioned structure, in the normal state when the driver's cab 1 is in the boarding position, the piston rod 11 is contracted as shown in FIG.
The pin 15 has been pivoted to a position away from the engaging portion 16. Therefore, when driving, etc., the driver's cab 1 and chassis 2
When there is relative rocking between the two, the rocking member 13 swings around the first pin 14 or the second pin 15, absorbing the relative rocking between the driver's cab 1 and the chassis 2.

1 is expanded. This causes the swinging member 13 to move to the first position.
The second pin 14 rotates in the direction of the hinge bracket 6 and engages with the engaging portion 16 of the second pin 15. Therefore, after the second pin 15 engages with the engaging portion 16, the extension force of the piston rod 11 acts on the driver's cab 1, and the driver's cab 1 tilts forward about the pivot 7 as a fulcrum. Further, when the forward-inclined driver's cab 1 is moved downward, the contraction force of the piston rod 11 acts on the engaging portion 16 with which the second pin 15 is engaged, and performs the initial movement of the driver's cab 1 to descend. and second
The pin 15 is guided by the arcuate surface of the engaging portion 16 and is removed from the engaging portion 16.

に行う利点がある。 As described above, according to the present invention, communication between the driver's cab and the piston rod of the hydraulic cylinder for tilting the driver's cab forward is established by connecting one end of the swinging member to the bracket fixedly installed on the driver's cab side using the first pin. a radius circle centered on the first pin which is pivotally connected, the other end of the swinging member is connected to the piston rod by a second pin, and the second pin engages the bracket from above when the piston rod is extended; Since the configuration has an arc-shaped engagement part, it allows the rocking motion of the resilient suspension of the driver's cab during driving, etc., and still ensures the forward tilting movement of the driver's cab, as well as the ability to lower the driver's cab. In some cases, the force for the downward movement of the piston rod is applied to the engaging portion by the second pin, which has the advantage of smoothing the initial movement of the downward movement of the driver's cab.
