Abstract

The invention discloses a double metal strap stepless speed change device, comprising a drive shaft and a driven shaft, wherein, a drive shaft is provided with a left drive fixed conical disk, a left drive movable conical disk, a right drive fixed conical disk, a right drive movable disk and a right metal strap; a driven shaft is movably provided with a left driven movable conical disk, a left driven fixed conical disk, a right driven movable conical disk and a right driven fixed conical disk. The invention is characterized in that: a counter balance spring is arranged between the left drive movable conical disk and the right drive fixed conical disk; the left drive movable conical disk is connected with a first sleeve which is connected with the right drive movable conical disk through the right drive fixed conical disk; a pressure spring is arranged between the left driven fixed conical disk and the right driven movable conical disk; and the left driven movable conical disk is connected with a second sleeve which is connected with the right driven movable conical disk through the left driven fixed conical disk. A structure can be greatly simplified by adopting the sleeves to be connected with two movable conical disks which are coaxial; a compression speed regulating system adopts mechanical pressurization and designs an axial pressure-balanced device with compact and efficient structure, thereby speed regulation by a miniature motor can be realized. The device has the advantages of simple structure, small volume, large speed change range and simple control.

Description

technical field [0001] The invention relates to a continuously variable transmission device, in particular to a bimetallic belt continuously variable transmission device applied to an automobile transmission system. Background technique [0002] The metal belt (chain) type continuously variable transmission (CVT) can realize the continuous change of the transmission ratio, so as to realize the best match between the transmission system and the engine working conditions, improve the fuel economy and power of the vehicle, and improve the driver's control Convenience and ride comfort of the occupants, so it is an ideal car transmission. However, the metal belt continuously variable transmissions currently on the market have two shortcomings. First, the transmitted torque can only reach 260Nm, which is limited in the application of high-power vehicles; second, they all use energy-consuming The fuel economy of the hydraulic servo system is only comparable to that of a manual tra...
