Below with reference to Fig. 1-Fig. 4, describe according to the vehicle 1 of the utility model embodiment.As Figure 1-Figure 4, according to the vehicle 1 of the utility model embodiment comprise vehicle frame 10, change speed gear box 20, the crossbeam 30 that suspends, a left side suspend part 40 and the right side suspends part 50.Suspend part 40 and the right side of crossbeam 30, a left side that suspend suspends part 50 for connecting vehicle frame 10 and change speed gear box 20, change speed gear box 20 is supported on vehicle frame 10, and plays buffer action.
Vehicle frame 10 comprises left longeron 110 and right vertical beam 120, and left longeron 110 and right vertical beam 120 are spaced apart from each other.The suspend middle part of crossbeam 30 is connected with change speed gear box 20.For example, by bolt, be connected.The left side part 40 that suspends is connected to left longeron 110 and suspends between crossbeam 30 on above-below direction.The right side part 50 that suspends is connected to right vertical beam 120 and suspends between crossbeam 30 on above-below direction.For example, left side part 40 and left longeron 110, left side part 40 and the crossbeam 30 that suspends, right side part 50 and right vertical beam 120 and the right side part 50 that suspends that suspends that suspends that suspends can be connected by bolt with the crossbeam 30 that suspends.Wherein, above-below direction is Z-direction (short transverse of vehicle 1), and Y-direction is the Width of vehicle 1.
That is to say, in the short transverse of vehicle 1, left longeron 110, suspend crossbeam 30 and left part 40 threes' that suspend position relationship can be followed successively by the crossbeam 30 that suspends, a left side suspend part 40, left longeron 110 from top to bottom; Right vertical beam 120, suspend crossbeam 30 and right part 50 threes' that suspend position relationship can be followed successively by the crossbeam 30 that suspends, the right side suspend part 50, right vertical beam 120 from top to bottom.
For example, as depicted in figs. 1 and 2, in an optional embodiment of the present utility model, the lower surface at the middle part of the crossbeam 30 that suspends can be connected with the upper surface of change speed gear box 20.The suspend upper end of part 40, a left side can be connected with the lower surface of the crossbeam 30 that suspends, and the lower end of the left part 40 that suspends can be connected with the upper surface of left longeron 110.The suspend upper end of part 50, the right side can be connected with the lower surface of the crossbeam 30 that suspends, and the lower end of the right part 50 that suspends can be connected with the upper surface of right vertical beam 120.The distance suspending between crossbeam 30 and the floor 70 of vehicle 1 is Z1.
In the schematic diagram of conventional truck 1 ˊ as shown in Figure 5 and Figure 6, vehicle 1 ˊ adopts the form that suspends of Z-direction list suspension point, and the distance suspending between crossbeam 30 ˊ and floor 70 ˊ is Z2.Part 40 ˊ that suspend are connected to change speed gear box 20 ˊ and suspend between crossbeam 30 ˊ on above-below direction, and the left end of crossbeam 30 ˊ that suspend is connected with left longeron 110 ˊ and the right-hand member of crossbeam 30 ˊ that suspend is connected with right vertical beam 120 ˊ.
For example, in the situation that other condition constant (relative position on the relative position of vehicle frame 10 ˊ, change speed gear box 20 ˊ and floor 70 ˊ and vehicle frame 10, change speed gear box 20 and floor 70 is constant), Z1 is greater than Z2.Make thus Z-direction between change speed gear box 20 and floor 70 apart from increase, thereby avoided the interference between change speed gear box 20 and floor 70, met the requirement to fitting allowance when power system (comprising driving engine 300, change speed gear box 20 etc.) is arranged simultaneously.In addition, because suspension point number becomes at least two from one, thereby make the installation of described change speed gear box more firm.
In the short transverse of vehicle 1, left longeron 110, suspend crossbeam 30 and left part 40 threes' that suspend position relationship also can be followed successively by from top to bottom left longeron 110, a left side suspend part 40, crossbeam 30 suspends; Right vertical beam 120, suspend crossbeam 30 and right part 50 threes' that suspend position relationship from top to bottom also can right vertical beam 120, the right side suspends part 50, crossbeam 30 suspends.
