Title:
VARIABLE-DIAMETER CHAIN RING WHEEL AND VARIABLE-DIAMETER CHAIN RING WHEEL TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2021/115024
Kind Code:
A1
Abstract:
A variable-diameter chain ring wheel, comprising two conical discs (1) which are symmetrical along the same axis, a chain (4) between the conical discs (1), and a chain winding shaft (21) in a central through hole of the conical discs (1). An inner end of the chain (4) is connected to the chain winding shaft (21); an outer end of the chain (4) extends out from the two conical surfaces through recesses (10), surrounds the conical surface by a circle and then is connected to two sliding blocks (5) in two sliding grooves (50); the chain (4) surrounds the two conical surfaces in the circumferential direction to form a chain ring (41). Therefore, the diameter and the circumference of the chain ring of the variable-diameter chain ring wheel can be changed, so that when the variable-diameter chain ring wheel serves as a mechanical transmission piece, the effect is the same as a variable-speed transmission effect achieved by an ideal variable-diameter gear. The variable-diameter chain ring wheel transmission comprises the variable-diameter chain ring wheel and a transmission piece. When serving as an automobile transmission, the transmission has advantages of high manual gear transmission efficiency, large torque, continuous and smooth speed change of a mechanical continuously variable transmission (CVT), and small size.
