The specific embodiment
With reference to the accompanying drawings embodiments of the present invention are described.
Fig. 1 represents the upward view of operator's compartment 20 of the cab-over-engine vehicle of present embodiment, and Fig. 2 represents the lateral plan of operator's compartment 20.
Front end bottom and rear end lower at operator's compartment 20 are respectively equipped with front cross rail 21 and the after cross member 22 that extends along the left and right directions of operator's compartment 20.In addition, in the bottom, left side of operator's compartment 20 and lower right side be provided with longeron 23, the longeron 23 of the lower surface that is used to support the ground-surface floor that forms operator's compartment 20, this longeron 23 extends along the fore-and-aft direction of operator's compartment 20.Longeron 23 its front ends combine with the trailing flank of front cross rail 21, and its rear end combines with the leading flank of after cross member 22.The following chamber body of operator's compartment comprises front cross rail 21, after cross member 22, longeron 23, longeron 23 and floor.
Below the joint portion between front cross rail 21 and the longeron 23, be provided with front coil spring 24a; Below the joint portion between after cross member 22 and the longeron 23, be provided with rear coil springs 24b.By this coil spring 24a, coil spring 24b on the chassis 26 (Fig. 3 A) upper support operator's compartment 20.Front coil spring (being equivalent to the 1st spring) 24a and rear coil springs (being equivalent to the 2nd spring) 24b are not limited to adopt coil spring, can adopt elastic components such as air bellow or rubber.
As shown in Figure 2, the length that makes the regulation among the lower surface 23b of longeron 23 of the 23a vicinity, joint portion between longeron 23 and the front cross rail 21 tilts towards the front upper place of operator's compartment 20 and forms longeron 23.
Fig. 3 is the enlarged drawing of the front end bottom of operator's compartment 20, and it is used for representing in detail the operator's compartment mounting structure of present embodiment.
In the present embodiment, front cross rail 21 is combined with longeron 23, and front cross rail 21 and longeron 23 are connected by the cab mount bracket 25 that will descend the chamber body to be connected with chassis 26 with joint portion 23a.The cross section at the rear portion of cab mount bracket 25 forms コ word shape, and this cab mount bracket 25 encases longeron 23 (Fig. 3 B) from the below.With bolt 27 the rear portion of cab mount bracket 25, cab mount bracket 25 and longeron 23 are connected by the position at rear than the bevelled lower surface 23b of longeron 23, and cab mount bracket 25 be connected on the chassis 26 and be connected to can with the perpendicular axle AX of the fore-and-aft direction of operator's compartment 20 be that the center freely swings with respect to chassis 26.In addition, the front portion of cab mount bracket 25 extended towards the place ahead of the trailing flank of front cross rail 21 be set near the leading flank of front cross rail 21, at the front end 25a place of cab mount bracket 25 leading flank of cab mount bracket 25 and front cross rail 21 is connected with bolt 28.
Be equipped with front coil spring 24a in the space that forms in the place ahead of longeron 23 tilting upward by the lower surface 23b that makes longeron 23.Front coil spring 24a is installed between the spring perch 25b of spring perch 26a that is formed on the chassis 26 and the front portion that is formed at cab mount bracket 25, and elastic support operator's compartment 20 on chassis 26.In addition, front coil spring 24a is positioned at the forward position of bevelled lower surface 23b than longeron 23 under this is provided with state, and by cab mount bracket 25 from about surround, cab mount bracket 25 the place ahead of the lower surface 23b of longeron 23 be in front coil spring 24a about each side extend (Fig. 1).And, be set on the position identical substantially at the leading flank of front coil spring 24a on the fore-and-aft direction of operator's compartment 20 with the leading flank of front cross rail 21.
Can obtain following effect according to present embodiment.
The 1st, in the present embodiment, by on the longeron 23, the lower surface 23b of the longeron 23 of the 23a vicinity, joint portion between longeron 23 and the front cross rail 21 is tilted towards the front upper place of operator's compartment 20, and be formed for setting the space of front coil spring 24a in the place ahead of this bevelled lower surface 23b.Therefore, not being moved upward longeron 23 just can make front coil spring 24a be moved upward.That is, in the present embodiment, can not dwindle the operator's compartment interior space and not increase the total length of vehicle, and make front coil spring 24a, promote the ride comfort of operator's compartment 20 along the vertical direction near the center of gravity of operator's compartment 20.
Fig. 5, Fig. 6 represent the operator's compartment mounting structure of the comparative example that conduct and the foregoing description compare, and in this operator's compartment mounting structure, cab mount bracket 4 is installed on the lower surface of longeron 3, and they combine with the trailing flank of front cross rail 2 jointly.In this operator's compartment mounting structure, desire to make the spring 5 that is equivalent to front coil spring 24a along the vertical direction near the center of gravity of operator's compartment 1, the longeron 3 that is fixed with cab mount bracket 4 is moved upward, can cause the floor (not shown.) the position on rise and the height of the operator's compartment interior space diminished.In addition, if not only guarantee the height of the operator's compartment interior space but also spring 5 is moved upward, and make spring 5 move to the place ahead below of front cross rail 2, then for the total length that makes vehicle within the limits prescribed, the length of railway carriage is dwindled etc.
In the present embodiment, be set on the position identical substantially by side especially with the leading flank of front cross rail 21 with front coil spring 24a, thereby can promote the ride comfort of operator's compartment 20 to greatest extent with front coil spring 24a configuration upward to greatest extent in the scope that does not increase length over pulling faces of cou plers.
The 2nd, in the present embodiment, front cross rail 21 is directly combined with longeron 23, and front cross rail 21 and longeron 23 are connected with cab mount bracket 25 with joint portion 23a.Therefore, can utilize cab mount bracket 25 to replenish anchoring strength, can utilize joint portion 23a and cab mount bracket 25 to obtain the anchoring strength that needs between front cross rail 21 and the longeron 23.
The 3rd, in the present embodiment, the lower surface 23b by making longeron 23 tilts towards the front upper place of operator's compartment 20, can reduce front cross rail 21, be used for the below overhang that combines with longeron 23.Therefore, can reduce the size up and down of front cross rail 21, reduce the manufacturing cost of front cross rail 21.About this point, in the structure of above-mentioned comparative example (Fig. 5, Fig. 6), front cross rail 2 itself and longeron 23 with and and cab mount bracket 4 between place, joint portion sagging significantly (Fig. 6), can increase manufacturing cost.
Fig. 4 represents the cab mount bracket 25 of another embodiment of the present invention.In the present embodiment, widened the width of the front end 25a of cab mount bracket 25, on this front end 25a, utilized bolt 28 to be formed with a plurality of binding fixed parts to the left and right directions of operator's compartment 20.Structure beyond the front end 25a is identical with the structure (Fig. 3 etc.) of previous embodiment.According to present embodiment, widen the width of the front end 25a of cab mount bracket 25 by direction to the left and right, and about be set up in parallel and be used on front cross rail 21 the binding fixed part that links, can guarantee to have high bond strength with respect to the twisting resistance that is applied to down the chamber body.
More than utilize several the present invention that preferred embodiment illustrated, but scope of the present invention is not subjected to any restriction of above-mentioned explanation, should be described based on the claim scope, judge according to suitable clause.
