Abstract

PROBLEM TO BE SOLVED: To provide a connecting device for the car body and axles of a crawler-mounted construction machine which does not require high accuracy for machining pin and a pin hole, facilitates the connection of the pin at the time of assembly, and lessens the play between the pin and the pin hole, and prevents the occurrence of troubles caused by the seizure of the pin. SOLUTION: A connecting part 24 is arranged in a projected manner at the four corners of a car body 21, while an opening part 25 is provided to an axle 22 in such a manner that the opening part 25 corresponds to the connecting part 24. The connecting part 24 is inserted into the opening part 25, so that a bracket 30 on the car body 21 side is connected with a bracket 31 on the axle 22 side through pin connection of a link 26. Since there is a gap between the connecting part 24 and the opening part 25, positional mating between a pin hole 32 of the brackets 30, 31 and a pin hole 33 of the link 26 can easily be made, so that the play between a pin 34 and the pin holes 33, 34 can be minimized. In addition, gap adjusting tools 27, 28 are installed in the gap between the connecting part 24 and the opening part 25 in order to regulate the gap.

In a conventional construction machine of this type, a mounting bracket on the car body side is joined to a support bracket on the axle side, and pins are inserted into two upper and lower portions of both brackets to connect with the car body. Axle is connected. Since the pin diameter tolerance is determined by the tolerance of the pin hole and the tolerance of the vertical pitch, the vertical pitch must be extremely accurately processed. If the vertical pitch is not accurate, it is necessary to reduce the pin diameter or increase the pin hole to increase the play between the pins.
