The invention discloses a chassis of a low-floor trailer body. The chassis comprises a bolster, longitudinal beams, side beams and seat support beams, wherein the bolster transversely penetrates through the whole trailer body; the bolster comprises a bolster lower cover plate, a bolster upper cover plate, a bolster side plate, a bolster vertical plate and a bolster support plate; the longitudinal beams are connected to two sides of the middle of the bolster respectively; each longitudinal beam comprises an end beam and a longitudinal beam body and further comprises a longitudinal beam lower cover plate, a longitudinal beam upper cover plate, an end plate, an end cover and a longitudinal beam side plate; the longitudinal beam lower cover plate extends horizontally at the end beam, then obliquely and upwards extends and finally horizontally extends; the longitudinal beam upper cover plate extends horizontally at the end beam, then obliquely and upwards extends and finally horizontally extends; a horizontal plane is taken as a standard, the angle between the obliquely and upwards extending longitudinal beam upper cover plate and the horizontal plane is smaller than the angle between the obliquely and upwards extending longitudinal beam lower cover plate and the horizontal plane, and the cross sections of the obliquely and upwards extending sections of the longitudinal beam upper cover plate and the longitudinal beam lower cover plate are gradually reduced. The chassis structure is light in weight, good in strength and stiffness and most importantly good in force transmission performance.
