The invention provides a tricycle carriage bearing structure which comprises left and right longitudinal beams and a carriage tail section connected to the tails of the left and right longitudinal beams, wherein the tails of the longitudinal beams are provided with a first connecting journal; the front end of the carriage tail section is provided with a second connecting journal; and the first connecting journal is connected with the second connecting journal in a staggered mode. Each longitudinal beam is composed of two parts, and the length of the whole longitudinal beam can be regulated by regulating the length of the carriage tail section, thereby satisfying the mounting requirements for multiple carriages with different specifications; and the tricycle manufacturer does not need to manufacture multiple longitudinal beams with different lengths, thereby lowering the manufacturing cost.
