Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle chassis, in particular to a high-pressure accessory integrated support and a vehicle chassis. BACKGROUND

[0002] With the continuous improvement of global environmental awareness, the environmental performance of new energy vehicles has become an important advantage for their future development. Therefore, new energy vehicles are valued by various automobile manufacturers, and various automobile manufacturers have launched new energy commercial vehicles one after another. New energy conventional chassis accessories (such as air compressors, air conditioning water pumps, steering oil tanks, storage batteries, etc.) and high-pressure accessories (such as high-low voltage controller assemblies, multi-in-one control assemblies, high-pressure junction boxes, etc.) are important components of vehicles, and their mounting supports are mainly connected to the vehicle frame through bolts, mainly for providing electrical energy, gas energy and control strategies for vehicles.

[0003] At present, the new energy commercial vehicle chassis accessory support assembly under the cab can be divided into three categories:

[0004] (1) Layered: The upper end of the support assembly is mainly installed with high-low voltage junction box assemblies, steering oil tanks, etc., and the lower end of the support is mainly installed with storage batteries, steering pumps, air conditioning compressors, etc. The support is based on the frame web, and the upper and lower supports are independent. When installing, the lower support is installed first, and then the upper support is installed. When disassembling, the upper support is disassembled first, and then the lower support is disassembled.

[0005] (2) Independent: Most of the chassis accessories and high-pressure accessories are installed on the frame in the form of independent supports. This structure has good independence, less interference with other accessories, and flexible disassembly and assembly, but has the disadvantages of complex installation of various parts, complicated and time-consuming installation process on the production line, and heavy overall weight.

[0006] (3) Integrated: The upper and lower supports are connected and installed together based on the layered structure. When assembling, the lower support is installed off-line, and then the whole is hoisted on-line. When disassembling, the cab is lifted up, and then the upper support is disassembled. The lower support can be disassembled and maintained separately in the trench, which is inconvenient for maintenance. When arranging, the installation process of each part, maintenance characteristics, wire harness and pipeline layout, and reasonable distribution of parts need to be considered, and the design workload of the support installation is large.
