Detailed description of the invention

Fig. 1 shows the driver's cabin 1 of Work machine, and this driver's cabin 1 is arranged on the platform upper surface of cab frame, and the platform supports of cab frame is on bearing.In driver's cabin 1, it is provided with multiple control device or display device etc., is respectively used to the information controlling the actuator of Work machine or being obtained by the sensor of Work machine for display.These control device or display device is electrically connected with respective actuator or sensor by electrical cable respectively.The cable being connected with the device controlled in device or display device or other driver's cabin is merged into a principal wire bundle 2 and is fettered by constraint material in outside, this principal wire bundle 2 is drawn downwards from driver's cabin via the cable-through hole of cab bottom and extends to rest base in the side of cab frame, principal wire bundle 2 extends to the edge of wheelhouse flat towards opposite side at rest base and extends past at the edge 7 of described wheelhouse flat and mud guard 4 further, and the narrow zone formed between 5 arrives above wheelhouse flat.Being formed with gap at cab frame with the adjacent region of mud guard 4,5, the especially B post lower end at cab frame is configured with recess, and this recess limits narrow zone.Principal wire bundle 2 is folded upward at via this gap this recess in other words and extends to above wheelhouse flat along B post, is then drawn towards corresponding actuator, sensor or other device to be connected.Certainly, principal wire bundle is fixed with cab frame parts by multiple clips on its whole extended link, to guarantee that wire harness does not rocks.

Fig. 2 and Fig. 3 respectively illustrates the different forms of implementation that principal wire bundle is arranged in the region that cab frame and mud guard are adjacent.For simplicity's sake, describe and the difference of the existing scheme shown in Fig. 1 at this emphasis.

Fig. 2 illustrate only the partial view of cab frame and mud guard neighboring region.As can be seen from Figure, principal wire bundle fetters by fettering material 6 in outside, this constraint material preferred direct-on-line cable weaves and forms；In the region that cab frame is adjacent with mud guard, first principal wire bundle 2 splits into two branching beams 8 at a branch point, 9, described the branching beam narrow zone between cab frame and mud guard along different paths, the especially narrow zone between bottom plate of driving cab 7 and mud guard 4 respectively.This branch point is preferably provided at the position before narrow zone at this.Certainly at this, principal wire bundle can also be split into the branching beam of more than two.Branching beam after fractionation can connect by clip and adjacent cab frame parts are fixing and extend to above wheelhouse flat along different paths respectively, such as one branching beam upwardly extends via the recess of B post 3, and another with branching beam spaced arrange.Certainly, the path of branching beam can also have other to select, and is not limited only to this, as long as can ensure that branching beam is not extruded and the least with the friction of circumferential component when vibration.

After this narrow zone, each branching beam can split into new branching beam 11 after point again converges and is incorporated in point 10 again, 12, new branching beam is by along different Route guidings to corresponding device, such as one along wheelhouse flat side, another is along bottom wheelhouse flat.It is to say, be formed with closed-loop between branch point and point, the branching beam in this closed-loop is preferably surrounded by a kind of jacket formed by the finest and close constraint material.Owing to again converging at point, cable can be repartitioned as required, and will extend over the consistent cable in direction and be arranged in new branching beam.

Preferably all cables with solder joint are arranged in same branching beam, and this branching beam comprising solder joint is arranged on higher position.It is of course also possible to consider the scheme not having point, i.e. after being branched off from principal wire bundle, branching beam converges the most again, but is directly communicated to corresponding actuator or sensor etc. along different paths.

Fig. 3 shows the view similar with Fig. 2, and the difference with Fig. 2 essentially consists in does not has recess in B post lower end, and wherein branching beam extends directed along the side with the adjacent B post lower end of bottom plate of driving cab 13.
