Abstract

DC60 (19/03/56) in a non-sequential transmission that operates variable speed transmission. By the movement of the carrier supporting the rotating parts, the speed changes which are in contact with friction with the driving and rotating parts to make it possible to reduce the size of the electric motor and This makes the speed change look fast. as well as to make the ability to work and the ability to assemble a complete set and to reduce the number of component parts Also, in order to accurately determine the position of the conductors at the "maximum" speed ratio conditions, to achieve the above, the drive screw 46, capable of rotating around the axis of the drive shaft, 26 is coupled to the screw. According to 45, which is fixed on a non-rotating carrier 29 Around the axis of the transmission shaft 26, the velocity mechanism 48, comprising a swivel gear wheel 52, is assembled in one piece by a limiting protrusion 54, which is fixed to the drive thread 46 and is provided The protrusions across the thread 45 are arranged between the electric motor 47 and the driving thread 46, and the thread 45 is arranged as one piece with the contact part 55 for contact and hooking. Coordinate with the limiting protrusion 54 when the thread of 45 is moved towards the gear wheel turning 52 until it reaches the position where the speed change ratio is at the ratio condition. The "maximum" velocity change in a non-sequential transmission that operates variable velocity transmissions. By the movement of the carrier supporting the rotating parts, the speed changes which are in contact with friction with the driving and rotating parts to make it possible to reduce the size of the electric motor and This makes the speed change look fast. as well as to make the ability to work and the ability to assemble a complete set and to reduce the number of component parts Also, in order to accurately determine the position of the conductors at the "maximum" speed ratio conditions, to achieve the above, the drive screw 46, capable of rotating around the axis of the drive shaft, 26 is coupled to the screw.

"Max" speed change

Claims (1)

Disclaimers (all) that will not appear on the advertisement page: 1.Continuously variable transmission unit This includes the transmission shaft (26) which is supported to rotate on the housing (19) so that the power from the engine (E) can be supplied. With such part, the driving pivot part (27) which is connected not to rotate relative to that of the transmission shaft (26), the pivot part (28) which is supported to rotate. It is on the transmission shaft (26), the carrier (29) that can be moved along the axis of the transmission shaft (26), the support shaft (30) which is supported on the conductor (29). While the axis is located along the origin of the cone, which Its middle line is The axis of the transmission shaft (26), and the speed shift part (31), which were supported to rotate and move axially on the support shaft (30), while having a surface The first friction conical (40) is supported by the conical (40) contact with the rotating part (27), and the transmission surface by the second friction conical (41) supports the frictional contact with the rotating part. (28) that, where the drive screw (46) which is supported on the housing (19) while being able to turn around The axis of the transmission shaft (26) is driven into a thread (45) that is firmly fixed to the conductor (29), which is attached to the housing (19), the thread along ( 45) that cannot It rotates around the axis of the transmission shaft (26) and is capable of moving only in the direction. Axially simultaneously with that conductor (29) only, on the other hand the drive helix (46) is capable of Only in rotation, and where the speed reduction mechanism (48) including the gear wheel (52) fixed to the driving thread (46) is positioned between the electric motor (47). Supported by the housing (19) and the drive thread (46), the gear wheel (52), which has a lateral surface opposite the conductor (29), is arranged. The frame shall be formed as one piece with a limiting overhang (54) extending to the opposite side of the thread under (45), on the other hand, the thread under (45) having opposite side surfaces. With the gear wheels in accordance with (52), the configuration is arranged in one piece with the contact support (55) so that it does not protrude from that side surface. The lean touch (55) has been configured. To support and About The limiting protrusion (54) is single, corresponding to the movement of the thread in accordance with (45) approaching the rotating gear wheel (52) until it reaches the position where the gear ratio ( 27) that with the rotating part according to (28) it enters the "maximum" gear reduction ratio.
