设计四轮智能小车的整体结构尺寸:长为740 mm,宽为378 mm,高

The overall structural dimensions of the four-wheeled smart car are designed: length 740 mm, width 378 mm, and height 477 <br>mm. Considering that the car body is mainly used to support goods and all ancillary equipment, the car body needs to have a certain <br>strength and rigidity, and the material uses Q235 ordinary carbon structural steel. The mass <br>of the overall mechanical structure of the designed trolley is 62 kg, and the maximum load that the trolley can bear is no more than 80 kg. In order to ensure that <br>the life and wear of the four wheels of the smart car are relatively uniform, it is required <br>that the load on the four wheels is not much different regardless of whether the car is at full load or no load . .

Design the overall size of the four-wheel smart trolley: 740 mm in length, 378 mm in width and 477<br>Mm. Considering that the car body is mainly used to support the goods and all ancillary equipment, the car body needs to have a fixed<br>Strength and stiffness, the material uses Q235 ordinary carbon structure steel. The quality of the overall mechanical structure of the designed car<br>At 62 kg, the trolley can withstand a maximum load of no more than 80 kg. In order to be able to guarantee the smart car four<br>The wheels have a relatively uniform life and wear, requiring four cars, whether at full or empty stationary<br>The load on the wheels is not very different, and the mechanical design parameters of the trolley are shown in Table 2-1.

The overall structural dimension of the four-wheel intelligent car is designed: 740 mm in length, 378 mm in width and 477 in height<br>mm。 Considering that the car body is mainly used to support goods and all auxiliary equipment, the car body needs to be equipped with one-to-one<br>The strength and rigidity are made of Q235 ordinary carbon structural steel. The quality of the whole mechanical structure of the designed trolley<br>It is 62 kg and the maximum load that the trolley can bear is not more than 80 kg. In order to guarantee four intelligent cars<br>The service life and wear of wheels are relatively uniform. It is required that no matter the trolley is in full load or no-load static state, four wheels<br>There is no significant difference between the loads on wheels, and the mechanical design parameters of the trolley are shown in table 2-1.
