Semi-trailing full-load-bearing highway passenger vehicle body structure

Abstract

The invention discloses a full-load-bearing body structure for a semi-trailing large highway passenger vehicle. According to the semi-trailing full-load-bearing passenger vehicle body structure, a bearing section (1) on a left side wall and a bearing section (2) on a right side wall of a vehicle body are in through frame structures with inclined supports, a connection position of the vehicle body and a traction frame is in a dual-section supporting structure, the front portion of a rear suspension of the vehicle body is in a dual-section supporting structure, the rear portion of the rear suspension of the vehicle body is in a single-section supporting structure, a front passenger door (3) is arranged on a front wall of the vehicle body, front door steps are divided into two portions which are steps (4) inside the vehicle and steps (5) outside the vehicle, a rear passenger door (6) is arranged on the rear section of the right side of the vehicle body, rear door steps are divided into two portions which are steps (7) inside a keel and steps (8) outside the keel, and steps (8) outside the keel and a toilet (9) are arranged on the left side and the right side of an underframe central keel rear suspension section respectively. The overall body structure is stressed, overall rigidity and strength performances are improved, the body weight reduction effect is obvious, the utilization ratio of the interior space is high, and the passenger capacity, the luggage compartment capacity and the like of the body structure are obviously higher than those of traditional passenger vehicles.

Description

technical field [0001] The invention designs a novel full load-bearing bus body structure, in particular a full load-bearing body structure applied to semi-trailer highway buses. Background technique [0002] In the middle of the last century, semi-trailer buses once appeared in foreign urban public transport systems due to their advantages such as large passenger capacity, less impact from engine vibration and noise in the cabin, and low manufacturing threshold. However, due to technical reasons at that time, some problems were still difficult to overcome, such as the difficulty in ensuring timely communication between the occupants of the vehicle and the driver, the excessive length of the vehicle body making it difficult for the driver to grasp the surrounding conditions, the excessive weight of the vehicle body, and high fuel consumption. The application of passenger cars has gradually decreased and has been hard to find in recent years. [0003] In recent years, techno...
