Electric truck chassis

Abstract

The invention belongs to the field of truck chassis, and particularly discloses an electric truck chassis. The electric truck chassis comprises a truck frame. A front axle is installed at the front end of the truck frame. A rear axle is installed at the rear end of the truck frame. A supporting platform is arranged over the front axle. The supporting platform is detachably connected with the truck frame. The supporting platform is provided with a battery charger and a drive controller. A motor cooler, a steering booster pump, a DC-DC and a storage battery are installed at the front end of the truck frame. The steering booster pump and the DC-DC are arranged side by side. The storage battery is located between the DC-DC and the drive controller. The motor cooler is located between the drive controller and the storage battery. The most front end of the truck frame is provided with an air conditioner compressor. The middle of the truck frame is provided with a driving motor. The two sides of the truck frame are each provided with a power battery pack. The power battery packs and the driving motor are arranged side by side. The power battery packs and the drive controller are connected with a motor high-voltage wire. The battery charger is connected with the power battery packs through high-voltage wires. The electric truck chassis has the advantages that the structure is compact, the number of the adopted high-voltage wires is small, and arrangement is reasonable.

Description

technical field [0001] The invention relates to the field of truck chassis, in particular to an electric truck chassis. Background technique [0002] Electric trucks are vehicles powered by rechargeable batteries. With the increasing depletion of oil resources, electric trucks using electricity as a power source have attracted more and more attention. Pure electric trucks that completely use electricity as energy have the following advantages: no pollution, low noise, simple structure, convenient use and maintenance, high energy conversion efficiency, recyclable braking or downhill energy, and improved energy utilization efficiency. The cheap "valley power" of the power grid can be used at night to smooth the peak-valley difference of the power grid. Therefore, electric trucks have broad market prospects and huge social benefits. Most of the current electric trucks adopt the modification scheme of existing fuel vehicles, and borrow the chassis structure of existing fuel ve...

Problems solved by technology

[0003] Since the working area of ​​the truck will take up a lot of space, and the weight and quantity of the battery boxes are large, it will bring great difficulties to the overall layout of the truck

Improper arrangement will shift the center of gravity of the vehicle, affect the front and rear axle loads and operational stability, and cause traffic accidents; because the battery box is relatively heavy, it is easy to injure people or damage the battery box when it is replaced manually, which is very unsafe

In addition, because the electrical components are connected by high-voltage wires, the longer the high-voltage wires, the more damage the electric energy will cause, the higher the cost of the vehicle, the more troublesome the fixing of the high-voltage wires, and the higher the probability of failure due to wear and tear of the high-voltage wires. high
