Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a spine-type truck frame. Background Art

[0002] The primary function of a truck's frame is to support and connect the vehicle's various assemblies, maintaining their relative position and bearing various internal and external loads. A truck frame typically spans the vehicle's front and rear axles, commonly known as a beam. A traditional truck frame primarily consists of two longitudinal beams and several transverse beams. The longitudinal beams run from front to rear, supporting the wheels via the suspension, front axle, and rear axle.

[0003] Traditional vehicle frames, due to their width and height, occupy significant layout space. In actual vehicle layout, components are often mounted sideways on either side of the longitudinal beam, resulting in low utilization of the central space. Fuel-powered vehicles have a central drive shaft, which also makes relatively good use of this space. However, new energy trucks utilize significantly different components than traditional fuel-powered vehicles. Traditional frame structures preclude the placement of large components, such as battery packs, and also hinder the full utilization of the central space. Consequently, the vehicle must increase its wheelbase and utilize the space behind the cab to meet these layout requirements. This results in a series of issues, including increased vehicle length, a higher center of gravity, increased weight, a larger turning radius, and a compressed cargo box. Utility Model Content
