Abstract
A continuously variable transmission includes an input shaft and a shaft journal eccentrically connected thereto on which a transmission element is bearing supported, as well as an output shaft which is connected to the transmission element via a constant velocity joint. The transmission further includes a housing and a pulley accommodated in it having two axially displaceable pulley wheels spaced apart from each other and which are fixed in the housing in the direction of rotation, as well as an adjusting mechanism for varying the space between the two pulley wheels. The transmission element is located between the two pulley wheels and is formed by a ring that rolls down in the pulley on rotation of the input shaft.
Claims20
A continuously variable transmission comprising:
- a housing (16),
- an input shaft (1) bearing supported in the housing,
- an output shaft (13) bearing supported in the housing,
- a pulley (7) with two pulley wheels (7A, 7B) spaced apart from each other and provided with contact surfaces (8) running obliquely relative to the central axis and facing each other, of which pulley wheels at least one pulley wheel can be displaced in axial direction relative to the other pulley wheel,
- an adjusting mechanism for varying the travel radius of the push belt, and
- a transmission element (3) located between the two pulley wheels and provided with two lateral surfaces (3A) facing each other which are in contact with the contact surfaces (8) of the pulley wheels,
- wherein
- during operation the pulley (7) is secured relative to the housing (16) in the direction of rotation,
- the transmission element (3) is formed by a ring that rolls down in the pulley (7) on rotation of the input shaft (1),
- the continuously variable transmission furthermore includes a shaft journal (2) connected to the input shaft on which journal the transmission element (3) is bearing supported,
- the continuously variable transmission further includes a constant velocity joint (12) of which a first joint portion (12A) is connected to the transmission element (3) and of which a second joint portion (12B) is connected to the output shaft (13).
