Stepless speed change device capable of changing speed through bevel gear

Abstract

The invention discloses a stepless speed change device capable of changing the speed through a bevel gear. The stepless speed change device comprises a movable gear, the bevel gear, a driving wheel and a driven wheel, wherein a circle of gear teeth which are integrally arranged are arranged at the outer ring of the movable gear and mesh with tooth grooves in the outer ring of the bevel gear, and the diameter of the bevel gear is gradually increased from left to right. According to the stepless speed change device, the position of the movable gear on the bevel gear is controlled through a transverse electric push rod and a vertical electric push rod, so that the circumferential diameter when the movable gear rotates while being attached to the bevel gear can be reached, the purpose of stepless speed change can be achieved, the structure is simple, the use is convenient, the movable gear, the bevel gear, the transverse electric push rod, the vertical electric push rod and a motor jointlyachieve the purpose of changing the rotating speed of the driving wheel, so that the rotating speed of the driven wheel is changed, the purpose of stepless speed change is achieved, the control is simple, the overall structure is simple to disassemble and assemble and convenient to disassemble, assemble and maintain, and the corresponding use cost and the manufacturing cost are lowered.

Description

technical field [0001] The invention relates to the technical field of continuously variable transmission devices, in particular to a continuously variable transmission device transformed by helical gears. Background technique [0002] Continuously variable transmission, which uses the transmission belt and the variable working diameter of the main and driven wheels to transmit power, can realize the continuous change of the transmission ratio, so as to obtain the best match between the transmission system and the engine working conditions. Common CVTs include hydromechanical CVT and metal belt CVT. At present, there are more and more models using CVT in the domestic market, but the CVT device still has the following disadvantages in actual use: [0003] 1. The existing continuously variable transmission device changes the speed by changing the working diameter, but the conversion method is single, and the structure is complicated, which is inconvenient to use; [0004] 2. ...

Problems solved by technology

[0003] 1. The existing continuously variable transmission device changes the speed by changing the working diameter, but the conversion method is single, and the structure is complicated, so it is inconvenient to use;

[0004] 2. In order to achieve the purpose of changing the working diameter of the driving wheel or the driven wheel in the existing continuously variable transmission device, the internal structure design of the driving wheel and the driven wheel is complicated, which is inconvenient for disassembly and maintenance, which increases the relative cost of use and production. cost
