Abstract

The invention discloses a light-weight magnesium alloy passenger vehicle body framework which comprises a vehicle body framework body, a vehicle head framework installed at the front end of the vehicle body framework body, a vehicle tail framework installed at the rear end of the vehicle body framework body and multiple connecting mechanisms. Each of the vehicle head framework, the vehicle body framework body and the vehicle tail framework is composed of multiple magnesium alloy section bars in a connected mode, and every two magnesium alloy section bars are buckled and connected into a wholethrough the corresponding connecting mechanism. The potential quality hazards of welded metal fatigue and stress concentration are effectively overcome, the technical problem that a magnesium alloy ispoor in welding performance and the problem that magnesium alloy frameworks are high in riveting cost are solved as well, and connection of the magnesium alloy frameworks of a whole vehicle is reliable.

Description

technical field [0001] The invention belongs to the technical field of bus body structures, and in particular relates to a lightweight magnesium alloy bus body frame. Background technique [0002] In 2016, the total sales volume of passenger cars was 54.3%, and the sales volume of new energy buses accounted for 23.8% of the total bus market. The sales volume of new energy buses was 129,000, accounting for 25.3% of the total sales volume of new energy vehicles; Vehicles are facing elimination and renewal, and new energy buses are ushering in a period of development. The light weight of the vehicle body is very important for saving energy, reducing exhaust emissions, and indirectly increasing the energy density of the battery. According to statistical analysis, the weight of the vehicle can be reduced by 10%, and the fuel efficiency can be increased by 6-8%. The reduction is about 2.5-5g / Km, and the noise can also be reduced by 2 decibels. On the premise of ensuring the stre...
