Description

Technical Field

[0001] This utility model relates to the field of commercial vehicle manufacturing technology, and in particular to a hybrid commercial vehicle layout structure. Background Technology

[0002] Compared to conventional fuel vehicles and electric vehicles, hybrid commercial vehicles contain components from both fuel vehicles and electric vehicles, such as engines, engine cooling systems, motors, motor controllers, motor cooling systems, power batteries, power battery cooling systems, multi-function systems, after-treatment systems, urea tanks, and fuel tanks. The system is complex, and the chassis layout is difficult. A reasonable chassis layout is crucial for shortening the vehicle's design and production cycle and improving maintenance convenience. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a hybrid commercial vehicle layout structure that solves the problems of numerous component assemblies and difficult chassis layout in hybrid commercial vehicles, and offers high modularity and convenient maintenance.

[0004] This utility model is achieved using the following technical solution:

[0005] A hybrid commercial vehicle layout includes a cab mounted on a chassis, a battery frame at the rear of the cab, the battery frame being fixedly connected to the chassis by bolts, an air conditioning condenser and a condenser fan at the lower front of the cab, an engine cooling system arranged behind the condenser fan, an engine arranged behind the engine cooling system, the engine being connected to an electric motor and a transmission, and an air conditioning compressor located on the right side of the engine.

[0006] Furthermore, the battery frame includes a power battery, a battery controller, a motor controller, a multi-function controller, a motor cooling system, and a battery cooling system.

[0007] Furthermore, on the right side of the chassis, at the lower end of the battery frame, there is an exhaust SCR box, and behind the exhaust SCR box, a urea tank and a battery are arranged in sequence.

[0008] Furthermore, a steering motor, an oil filter, and a fuel tank are sequentially located on the left side of the chassis.

[0009] Furthermore, an electric air compressor unit is arranged on the left or right side of the chassis.

[0010] Furthermore, a spare tire is provided at the rear of the chassis.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] The fuel tank is located on the left side of the chassis; the urea tank and battery are located on the right side of the chassis; the battery frame is located at the rear of the cab. The power battery, battery controller, motor controller, multi-function controller, motor cooling system, and battery cooling system are all integrated and installed on the battery frame. This arrangement achieves a reasonable layout of various system components in the heavy commercial vehicle, with its center of gravity falling as close as possible to the longitudinal centerline of the chassis assembly, making the vehicle more stable during driving. The power battery and controller related to hybrid technology are centrally located on the battery frame, making the chassis layout as consistent as possible with the conventional diesel chassis layout, which has the advantages of high modularity and convenient maintenance.
