The invention discloses a soft bearing type folding bicycle which comprises a front section rod frame, the front end of the front section rod frame is movably connected with the front end of a rear section rod frame, the rear portion of the rear section rod frame is connected with an end cylinder, a saddle rod is sleeved with the end cylinder and inserted into a V-shaped supporting rod, the V-shaped supporting rod is connected with the lower surface of the rear section rod frame, and the lower end of the V-shaped supporting rod is connected with a shaft cylinder; a rotating shaft is sleeved with the shaft cylinder through first bearings which are symmetrically arranged, the two ends of the rotating shaft are symmetrically sleeved with first bevel gears, the first bevel gears are meshed with second bevel gears, the front end of a transmission shaft is sleeved with the second bevel gears, and the rear end of the transmission shaft is sleeved with third bevel gears and is sleeved with anend shell through third bearings, and the third bevel gears are arranged in the end shell and engaged with fourth bevel gears; the fourth bevel gears are sleeved at the shaft end of a rear wheel, thefront end of the front section rod frame is connected with a front fork frame in a penetrating mode, and a spring is arranged at the top of the sleeve and is pressed by a nut connected with the main pipe of the front fork frame. The soft bearing type folding bicycle is compact in structure and novel and unique in thought, the traditional chain transmission is improved by changing the force transmission direction through shaft transmission gear engagement, and the bicycle frame is high in bearing capacity.

    本发明公开了一种软承载式折叠自行车,包括前段杆架,前段杆架活接后段杆架的前端,后段杆架后部连接端筒,端筒内套装车座杆,并插入到V形撑杆内,V形撑杆连接于后段杆架的下表面,V形撑杆下端连接于轴筒上,轴筒内通过对称设置的轴承一套接转轴,转轴两端对称套接锥齿轮一,锥齿轮一啮合锥齿轮二,锥齿轮二套接于传动轴前端,传动轴后端套接锥齿轮三,并且通过轴承三套接于端壳内,锥齿轮三设于端壳内并啮合锥齿轮四,锥齿轮四套接于后轮轴端,前段杆架前端贯穿连接的套管内接前叉架,套管顶部设置弹簧,并通过连接于前叉架主管上的螺母压接;具有结构紧凑,思路新颖独特,利用轴传动齿轮啮合改变传力方向来改善传统的链传动,车架承载强。
