This paper contains the brief introduction about the body frame assembly characteristics and process requirements of the low floor bus.

The main technical parameters and equipment layout of Q6W-1 type 70% low floor Light Rail Vehicle with respect to the structure features of the low floor Light Rail Vehicle were introduced.

An independent wheelset has such characteristics,well hunting stability,less wear,low yawp,light weight and easy operation equipped with full low floor,compared with the traditional wheelsets.

Modeling and dynamics analysis of 70% low-floor light rail vehicles;

The scheme of a new type low-floor bogie with independent wheels(the coupling bogie with independent wheels), is given in this paper.

It is a integrated technology of leading domestic level low-floor bus chassis.

The article introduces the mecha-nism and features of the low-temperature floor radiation heating mode and analyzes the feasibility of adopting this heating mode in the areas of hot summer and cold winter.

This paper first discusses the advantages of low-temperature floor heating system such as it being clean,tidy,energy-saving,thermal stability and easy to handle,and then puts forward scientific installation and construction methods.

Described are the structure features, total assembly technology and some technological equipment for 70% low floor, light rail car-bodies.

Discussion on structure type of 100% low floor LRV
