TH33051A - Continuously variable transmission unit - Google Patents

Abstract

To provide a continuously variable power transmission capable of pushing the drive surface and The surface can be followed by using a cam mechanism. Pressure is only one mechanism And can prevent The constant pressure of the pressure-correcting cam mechanism can be forwarded to the housing. Continuous variable powertrain T consists of 29 driving surfaces supported around the outer perimeter of the input shaft 23, the 30 supported faces around the outer perimeter. Of output shaft 22, double cone 39, the number of multiple It is supported by the cone grips 31 in such a way that it will contact the face 29, 30 and the cam mechanism. The pressure sustained around the outer perimeter of the output shaft 22 The left-hand pressure exerted by the pressure-correcting cam mechanism 67 is forwarded to the pin shaft. Exit 22 through the output gear 66 and the split end pin 65, and press against the right hand of the cam mechanism. The pressure correction is forwarded to the output shaft 22 through the following face 30, double cone 39, drive face 29, inner half gear 26, casing 52, ball bearing 62, shaped casing. Step 59, Ball Bearing 60 and Split End Pin 61.

1. Power unit with variable speed transmission The powertrain (P) consists of the engine (E) and the continuously variable powertrain (T). The continuous variable transmission (T) consists of the driven surface (29). It is supported so that it rotates on the main transmission shaft (21), the surface in accordance with (30) that has been supported. Rotatable on the main transmission shaft (21) as above, cone grips (31,56) that can move along the Of the main transmission shaft (21), the double cone support shaft (37) is supported on the said cone grip (31,56) along the line of origin of the centered round cone along the Of the main transmission shaft (21), the double cone (39), formed from the first (40) and second (41) cones, which have a conical face. It is thus supported so that it rotates on the double cone support shaft (37) and the pressure correcting cam mechanism (67) for making the aforementioned drive surface (29) in contact with the first cone (40) as Said under pressure And make the surface (30) in contact with the second cone (41) under pressure It is unique in that the engine (E) and the continuously variable transmission (T) are arranged. It is contained in the common housing (1) and the conical holding proportions (31,56) are prevented from rotating by such housing (1). The main transmission shaft (21) consists of a pin shaft. The output shaft (22) mounted onto the aforementioned housing (1) and the input power shaft (23) is supported quickly for relative rotation but resists axial-directional movement around the perimeter of the The output shaft (22) is supported by the drive surface (29) as opposed to axial movement. On the aforementioned input shaft (23) and the aforementioned pressure correction cam mechanism (67) are supported. At one end of the mechanism against axial directional motion on the output shaft (22) thereof, the aforementioned surface (30) and the other end of the pressure-correcting penalty ball mechanism (67). It has been connected. The aforementioned (31,56) cone grips define the boundary of the space that surrounds it. Such as the output shaft (22) and the said input shaft (23) of the main transmission shaft (21), the said drive surface (29) and the propulsion mechanism. (51) For such cone grips (31, 56) to move along the main transmission shaft (21), it is contained inside. Of the cone grips (31,56), the oil path (22) is formed in the said output shaft (22) in such a way that it passes through the output shaft (22). In the axial direction and connected to the oil path (4/2) in the said housing (1) and the power transmission assembly The above continuously variable (T) was lubricated with the oil delivered from the said oil path (22/1) in the said output power (22) into the internal space of the Such (31,56) cone grips
