The trucks we use at the factory are shipped to all parts of the country in the form of a chassis when there are no special requirements. When a user purchases a car, they are basically the vehicle chassis purchased by the dealer or the dealer. Containers that have already been loaded, and users who buy chassis must modify the truck according to their own needs, that is, we say the tops, such as vans, lorries, high-liners, refrigerated trucks And so on, some will be converted into special vehicles and RVs, and the truck modification is the same as the modification of the car, there are specifications and precautions, and many truck users do not actually know, the following Xiaobian will propose 10 modifications for the user Recommendations, hope to help users.
1. After the chassis has been modified, the axle load on the front and rear axles must not exceed the maximum axle load quality allowed on the chassis.
(2) The total mass of products such as vans and slatted cars shall not be greater than the maximum load quality calibrated by the chassis used, nor shall it be less than 90% of the maximum allowable total mass.
Third, all modified cars and changes to the car should be implemented in accordance with the current state regulations.
Fourth, the refitting manufacturers shall be responsible for the design, manufacture and safety of all refitting devices; and shall be responsible for the correctness of connection between the refitting part and the chassis carrying system and the power output system, and shall not affect the entire car due to the general layout design of the refitting part. safety.
5. The conversion plant shall not dismantle, change, weaken and destroy the original structural components of the chassis for the purpose of installing the modified parts, or cause the chassis to be heavily loaded with stress concentration.
Sixth, the modified part should have enough space for maintenance, so that the relevant parts of the inspection, maintenance, lubrication, replacement and disassembly have a good proximity. When necessary, the compartment car chassis must have a corresponding maintenance activity cover.
7. After the refitted vehicle is driving on the vehicle, and the refitting part is in any motion state, it shall be ensured that friction, collision and interference do not occur between the refitting part and the original chassis member.
8. Pay attention to reduce the height of the center of gravity of the converted part (including the bearing quality) as much as possible and ensure that the axle load distribution of each axis does not exceed the maximum allowable shaft load of the plant to avoid the eccentric load between each axis and the left and right wheels.
9. When the selected chassis is a turnable cab, the cab shall be smoothly turned after the conversion.
Tenth, shall not affect the car's driving brake and steering performance due to modification.
The modification of trucks is actually very important. It directly affects the performance of the entire vehicle, such as safety, bearing, reliability, and so on. The conversion must be careful, and do not blindly pursue the bearing or speed and affect our normal use.
