Description

Technical Field

[0001] The utility model relates to the technical field of arrangement of chassis accessories of dump trucks, in particular to a chassis structure of a pure electric light dump truck. Background Art

[0002] As environmental and energy issues become increasingly prominent, the development of new energy vehicles has become the main measure to accelerate the strategic transformation of transportation energy. Major automobile manufacturers have also increased their research and development and industrialization efforts. Pure electric vehicles only use electricity as a power source and have many advantages such as high efficiency, low noise, stable driving and zero emissions.

[0003] At present, most pure electric vehicle chassis have replaced the engine with an electric motor, and the frame and chassis layout is unreasonable. For example, due to the limitations of the power battery and motor assembly, the dryer and air tank will be arranged on the inside of the frame longitudinal beam, resulting in the need to change the chassis layout when the lifting structure and wheelbase are different. The degree of chassis commonality is low, and production organization is difficult. Utility Model Content

[0031] To realize the universalization of the chassis structure of pure electric light dump trucks, see Figure 1-Figure 2 , Figure 4The present embodiment provides a pure electric light dump truck chassis structure, including a frame 1, a power battery frame 2, a motor assembly 3, a power battery control box 4, a dryer 5, an external air cylinder 6, and a hydraulic oil tank 7; the power battery frame 2 is provided with two and is symmetrically arranged along the two outer side walls of the upper longitudinal beam of the frame 1, and each of the power battery frames 2 is provided with at least one power battery, and for sufficient power support, the long side of the power battery frame 2 corresponds to the longitudinal beam of the frame 1, so that a plurality of power batteries are laid along the long side in the power battery frame 2, and further, a plurality of spaced support rods 2a are arranged in the power battery frame 2 to divide the plurality of power batteries, and the two ends of the support rod 2a are detachably connected to the power battery frame 2. The motor assembly 3 is arranged inside the longitudinal beam of the frame 1. Preferably, the motor assembly 3 is located between the two power battery frames 2, so that the gravity distribution of the frame 1 is more uniform and the length of the wiring harness is reduced to a certain extent, that is, the distance when the power battery supplies power to the motor assembly 3 is the shortest. A transmission is provided in the power assembly 3.
