Problems solved by technology

However, there are also technical difficulties in the design of the aluminum chassis. If the connection between the aluminum profiles in the chassis is riveted or screwed, it will increase the cost and weight. If the connection between the aluminum profiles is changed to welding, it will cause stress concentration at the weld. , the mechanical properties decrease

Abstract

The invention relates to an aluminum alloy underframe of a full-loading bus. The full-loading bus comprises a front underframe, a middle underframe, a rear underframe, a front middle floor skeleton and a rear floor skeleton which are formed by welding aluminum alloy sections. The aluminum alloy underframe of the full-loading bus adopts the aluminum alloy sections, and a real all-aluminum bus is realized; and the aluminum alloy sections are connected by adopting a welding mode, on the basis that the connecting strength is guaranteed, lightweight design is realized, weight is reduced more than 25%, and a favorable means is provided for achieving three stage fuel consumption; meanwhile anti-corrosion can be conducted on the aluminum alloy sections effectively, the electrophoresis process is canceled, the service life of the underframe is prolonged, and product competitiveness is enhanced.

Description

technical field [0001] The invention belongs to the technical field of passenger car manufacturing, and in particular relates to an aluminum alloy underframe of a full-load passenger car. Background technique [0002] According to the requirements of GB30510 "Fuel Consumption Limits for Heavy Commercial Vehicles", on May 26, 2015, the twelfth meeting of the third stage fuel consumption limit standards for heavy commercial vehicles initially proposed that in 2020, it will be reduced on the basis of the national standard in 2015. 20-25% target. [0003] Lightweight vehicles can reduce vehicle energy consumption and correspondingly reduce passenger car exhaust emissions, reduce air pollution, and at the same time improve vehicle handling stability, driving safety, ride comfort and other performance. Experiments have shown that if the weight of the vehicle is reduced by 10%, the fuel efficiency can be increased by 6% to 8%; for every 100 kg reduction in the curb weight of the v...
