Abstract

The invention discloses a continuously variable speed box. A power input shaft 1, a lead screw rod 3, a lead screw rod 8, a cone pulley 10 and a cone pulley 11 fixed on a frisket 15; an adjusting wheel 4 and a wheel 5 as well as an adjusting wheel 9 and a wheel 7 are respectively fixed on the lead screw rod 3 and the lead screw rod 8; a wheel 6 is fixed at the upper end of the power input shaft 1and matched with the wheel 5 and the wheel 7 for transmission; the lower end of the power input shaft 1 is installed with a power output wheel 14 which is matched with t a wheel 12 and a wheel 13 fortransmission which are installed at the lower ends of the cone pulley 10 and the cone pulley 11; the middle of the power input shaft 1 is also installed with a main wheel 2 which is matched with theadjusting wheel 4 and the adjusting wheel 9 for transmission. The continuously variable speed box of the invention has simple structure, easy fabrication, long service life, small variable resistanceand low manufacture cost, and is convenient for repair, thereby being applicable to different places requiring continuous variable speed.

Description

technical field [0001] The invention relates to a transmission speed changer. Background technique [0002] With the development of transmission technology, the vehicle transmission is also continuously improved. Chinese patent, patent No. ZL200620021308.5, titled "Automobile Transmission", the utility model relates to a vehicle transmission. The crankshaft of the engine is connected to the ring gear in the first planetary row. The first, second and third planetary rows are respectively connected to the ring gear in the second planetary row by the planet carrier inserted in the planetary gear of the first planetary row. The sun gear in the planet row is connected to the planet carrier inserted in the planet wheel in the third planet row, the sun gear in the first planet row is connected to the driven shaft, and the sun gear inserted in the planet wheel in the second planet row The planet carrier is fixed on the transmission casing, the ring gear in the third planetary row ...
