The invention discloses a base frame of a total load bearing type electric public bus and the electric public bus provided with the base frame. The base frame comprises a front part base frame, a middle part base frame and a back part base frame, wherein the front part base frame comprises a front door step and aisle zone framework, a driver zone framework, a left front wheel hub cover and a right front wheel hub cover; the middle part base frame comprises a middle door step and aisle zone framework, a middle part left passenger zone framework, a middle part right passenger zone framework and a battery pack mounting rack; the back part base frame comprises a back part step and aisle framework, a driving motor framework, a left rear wheel hub cover and a right rear wheel hub cover; the base frame adopts a trussed skeleton structure, at least one vehicle body connecting plate is respectively arranged on the two sides of the front part base frame, the middle part base frame and the back part base frame; the vehicle body connecting plates are provided with fixing holes for connection with the vehicle body. The base frame of the total load bearing type electric public bus is less in weight and large in rigidity, the problem that the welding technology cannot be achieved when the vehicle body and the base frame are made of different materials is solved, and the assembly efficiency is high.
Description
technical field [0001] The invention relates to passenger cars, in particular to an underframe of a fully loaded electric public bus and an electric public bus with the same. Background technique [0002] The current passenger car is generally a non-load-bearing or semi-load-bearing structure. The structure of the bus generally includes a chassis and a body. The chassis and the body are relatively separated. The chassis must bear the weight of itself and the body, as well as the engine installed on the chassis and the beam The weight of components; the body only bears its own weight and the weight of cargo and passengers, and does not bear the load of the chassis and underframe. The center of gravity of this kind of body is relatively high, and the stability of high-speed driving is poor. When being hit, the chassis and the body will produce relative displacement, and the strength of the whole vehicle is weak. [0003] In order to solve the above-mentioned problems, the pri...
