第三级地板125可以放置卧铺,从而方便驾驶员休息,其中第三级地板125远离工程车辆的车头。设置第二过渡地板124和第三级地板125以使驾驶室地板形成了三级台阶。因为第二级地板122和第三级地板125均具有一定的高度,从而将驾驶室后半段抬高,那么驾驶室下方具有较大的空间,即驾驶室下方与地面之间的有较大的空间,然后可以将驾驶室下移,从而降低了驾驶室的高度。另外第一过渡地板121和第二过渡地板124上均设置有卡槽,第一级地板121和第二级地板122均设置有与卡槽配合的凸起,且第一级地板121和第二级地板122可活动。驾驶员可以移动第一级地板121与第一过渡地板123上的任意一个卡槽连接,且第一过渡地板123上设有多个卡槽。驾驶员可以移动第二级地板121与第二过渡地板123上的任意一个卡槽连接,且第二过渡地板123上设有多个卡槽。其中,第二过渡地板124的一端与第二级地板122连接,第二过渡地板124的另一端与第三级地板123连接。The third-level floor 125 can place a sleeping berth, thereby facilitating the driver to rest, wherein the third-level floor 125 is away from the front of the engineering vehicle. The second transition floor 124 and the third floor 125 are provided so that the cab floor forms three steps. Because the second-level floor 122 and the third-level floor 125 all have a certain height, thereby the second half of the driver's cab is raised, there is a larger space below the driver's cab, that is, there is a larger space between the driver's cab and the ground. space, and then the cab can be moved down, thereby reducing the height of the cab. In addition, the first transition floor 121 and the second transition floor 124 are provided with draw-in grooves, the first-level floor 121 and the second-level floor 122 are all provided with protrusions that match the draw-in grooves, and the first-level floor 121 and the second The level floor 122 is movable.

As shown in FIG. 5 , the chassis of the engineering vehicle may further include wheels 13 , wherein two wheels 13 are disposed under the second-level floor 122 .
因为第二级地板122的高度高于第一级地板121的高度,第二级地板122的下方的空间正好可以放置两个车轮13,从而不会干扰车轮13正常的运转,同时也起到了降低驾驶室高度的目的。Because the height of the second-level floor 122 is higher than the height of the first-level floor 121, the space below the second-level floor 122 can just place two wheels 13, thereby not interfering with the normal operation of the wheels 13, and also reducing the wheel load. The purpose of cab height.
图6是本申请另一示例性实施例提供的工程车辆的底盘的结构示意图。如图6所示,两个车轮13之间的轴向中心点位于靠近第二级地板122远离工程车辆的车头的一侧位置,且轴向中心点与第二级地板122远离工程车辆的车头的一侧位置之间的距离L1小于或者等于480毫米。Fig. 6 is a schematic structural view of a chassis of an engineering vehicle provided by another exemplary embodiment of the present application. As shown in Figure 6, the axial center point between the two wheels 13 is located near the side of the second-level floor 122 away from the front of the engineering vehicle, and the axial center and the second-level floor 122 are away from the front of the engineering vehicle The distance L1 between the positions on one side is less than or equal to 480 mm.
两个车轮13之间的轴向中心点靠近第二级地板122远离工程车辆的车头的一侧位置,不影响驾驶室空间的大小,保证驾驶员有足够的乘坐空间和舒适性,同时也降低了驾驶室的高度。两个车轮13的轴向中心点与第二级地板122远离工程车辆的车头的一侧位置之间的距离L1介于0毫米到480毫米之间,在该区间内的距离不会降低驾驶室空间。The axial center point between the two wheels 13 is close to the side of the second-level floor 122 away from the front of the engineering vehicle, which does not affect the size of the cab space, ensures that the driver has sufficient seating space and comfort, and also reduces the height of the cab. The distance L1 between the axial center points of the two wheels 13 and the side of the second-level floor 122 away from the front of the construction vehicle is between 0 mm and 480 mm, and the distance in this interval will not lower the cab space.

因为将驾驶室的高度降低,因此可能没有空间适合放置动力总成14,那么可以将动力总成14设置在驾驶室地板12远离工程车辆的车头一侧,从而给驾驶室提供高度降低的空间,并且不影响动力总成的使用。另外,如果动力总成14安装在驾驶室地板的下方,容易将动力总成14产生的噪音传递到驾驶室的内部。因此通过将动力总成14设置在驾驶室地板12远离工程车辆的车头一侧,从而动力总成14产生的噪音不容易传递到驾驶室内部,从而降低驾驶室内振动噪音。Because the height of the cab is reduced, there may be no space suitable for placing the power assembly 14, so the power assembly 14 can be arranged on the side of the cab floor 12 away from the front of the engineering vehicle, thereby providing the cab with a reduced space, And it does not affect the use of the powertrain. In addition, if the powertrain 14 is installed under the cab floor, it is easy to transmit the noise generated by the powertrain 14 to the interior of the cab. Therefore, by arranging the power assembly 14 on the side of the cab floor 12 away from the front of the engineering vehicle, the noise generated by the power assembly 14 is not easily transmitted to the interior of the cab, thereby reducing the vibration noise in the cab.
