Can a Sedan Trunk Carry a Load of 600 Jin?

[KiraLynn]

A sedan cannot carry a load of 600 jin. Generally, the load capacity of a sedan is around 500 jin, and carrying 600 jin would already constitute overloading for a sedan. Below are the impacts of overloading on a car: 1. Reduced braking performance and increased non-safe zone distance: There are many factors affecting a car's braking distance, among which the change in vehicle load directly influences the length of the braking distance. Overloaded cars, due to increased inertia, have longer braking distances. The extension of the non-safe zone distance can easily lead to traffic accidents. 2. Shortened lifespan of leaf springs and reduced vehicle passability: Due to overloading, the leaf springs are subjected to excessive force and continuously rebound during driving, which will shorten their lifespan. Moreover, the excessive load causes the vehicle to sink overall, reducing the ground clearance and diminishing the car's passability. 3. Accelerated tire wear and deformation: Car tires are designed and manufactured based on the total weight of the vehicle, with a considerable safety factor. However, when a car is overloaded, the tires bear excessive weight and deform. Simultaneously, increased friction also leads to a shortened tire lifespan.
