Abstract
The utility model discloses a beam-free modularized passenger car underframe which comprises a front-section module, a front axle-section module, a middle-section module, a rear axle-section module and a rear-section module that are fixedly connected in sequence, wherein the modules adopt a grating structure formed by thin-wall rectangular pipes. The beam-free modularized passenger car underframe overcomes the defects that the existing passenger car underframe due to adopting a steel frame structure with a thick plate type groove type longitudinal beam and groove type internal and external beams. When the underframe is used for bearing load, a whole car housing can achieve a more stable and balanced state, thus effectively improving the NVH (noise, vibration and harshness) performances of a passenger car; and not only can the underframe realize the lightweight of the passenger car, improve the performances of the whole car, reduce the oil consumption and lower the manufacturing cost, but also the length of the underframe can be adjusted according to the requirement of car models with different length. The car underframe is simple in structure, high in strength, strong in anti-torque capability, and high in university, thus representing the future development direction of transit passenger cars.
Description
Technical field
The utility model relates to city bus, relates in particular to a kind of no crossbeam modularization underframe of coach.
Background technology
The underframe of coach that uses generally adopts slab grooved longeron and the inside and outside crossbeam welding of flute profile or riveted joint to get up to become a steelframe at present, encloses with front and back with body platform, left and right sides gusset by welding or bolted connection to be connected.There is following defective in it: the one, because the Undercarriage structure integral rigidity is big, the vibration that can not actv. absorbs ground and driving engine transmission and come, influence NVH(Noise noise, Vibration vibration and the Harshness sound vibration roughness of passenger vehicle) performance, especially when bumping, can not absorb collision energy by actv., passive satety is relatively poor; The 2nd, owing to adopt thick channel-section steel, the underframe quality is bigger than normal, oil consumption and manufacturing cost height, and the 3rd, the pipe line arrangement difficulty lacks commonality between the different length vehicle.
