A swingable shaft-driven tricycle, comprising a front frame (1), a rear frame (2), and a transmission mechanism, the front frame (1) is connected to the rear frame (2) through a swinging mechanism (3), the transmission mechanism comprises a front torque output assembly (4) arranged on the front frame (1) and a second torque output assembly (5) arranged on the rear frame (2), wherein the first torque assembly (4) transmits torque to the second torque output assembly (5) through a transmission shaft (6), and the second torque output assembly (5) is in linkage cooperation with at least one of two rear wheels (72). The tricycle solves the problem in the prior art that when swinging occurs between a front frame and a rear frame, a transmission agent needs to swing along with the frames, thus causing poor transmission reliability, and solves the problem in the prior art that a chain is prone to falling off when affected by jolts and vibrations, thus affecting riding experience or even safety.
A swingable shaft-driven tricycle, comprising a front frame (1), a rear frame (2), and a transmission mechanism, with a front wheel (71) being arranged on the front frame (1), two rear wheels (72) being symmetrically arranged on the rear frame (2), and the front frame (1) being connected to the rear frame (2) through a swinging mechanism (3);
