在させたことを特徴とする。Means for Solving the Problems: The present invention intends to solve the manufacturing cost problem that occurs when an automatic transmission using an R type transmission is installed in a light vehicle. A conical surface that frictionally engages with the inner peripheral surface of the speed change ring, a transmission surface that frictionally engages with a small diameter transmission wheel on the input shaft, and a friction engagement with a large diameter transmission vehicle that has a central axis that matches the central axis of the input shaft. A plurality of conical rotors having matching transmission surfaces are provided on the transmission system, and depending on whether the rotation of the transmission ring is restricted or the rotation of the large diameter transmission wheel is restricted, A cam that transmits the power of the internal combustion engine to the axle via a friction continuously variable transmission of the type in which the rotation of the speed change ring is transmitted to the output shaft, and generates thrust of a magnitude corresponding to the magnitude of the torque applied to the speed change ring. A device is provided as load torque detection means, and In the automatic gear shifting that is performed by associating the control of the internal combustion engine with the detection of the load torque by the cam device, a spring seat is provided on the rod that moves in the centerline direction by an amount corresponding to the depression amount of the accelerator pedal.

速比の下の走行が行われ得るようにする。Action: When the accelerator pedal is depressed, the spring seat, the spring and the speed change ring support member are moved in the axial direction by the force applied to the spring seat from the accelerator pedal side. This movement attempts to move the shift ring toward the high speed side, but the shift amount of the shift ring differs depending on the magnitude of the thrust generated by the cam device. Since the generated thrust of the cam device is small when traveling on level ground, the amount of movement of the spring seat is close to the amount of movement of the transmission ring, and therefore the amount of movement of the transmission ring that goes toward the high speed side is large. Since the thrust is large, the amount of movement of the transmission ring is much smaller than the amount of movement of the spring seat, and in some cases, this amount of movement is 0 or a negative amount. The control performed while moving the spring seats in the above-described manner allows the vehicle to travel at an optimal gear ratio according to the state of the road surface.

The transmission system leading to is a cam in which the rotation of the speed change ring 4 is "a cam acting surface 7 provided on the speed changing ring 4 and a roller engaged with the cam acting surface 7 supported by the arm 8 on the output shaft 2. It is of the ring rotation type that is transmitted to the output shaft via the device 10 ". The cam device 10 functions as a load torque detecting means. Reference numeral 11 denotes an accelerating pedal, and a movement of a size corresponding to the amount of depression of the accelerating pedal 11 is transmitted to a rod 12 which can move in the axial direction through a linkage mechanism.

速比の下に車両の運転が行なわれるようにする。The position of the accelerator pedal 11 shown by the solid line and the position shown by the spring seat 13 at this position are when the depression amount is 0, and at that time, the transmission ring 4 sets the rotational speed of the output shaft to 0. At a position (this position is near the bottom of the conical surface). When the accelerator pedal 11 is stepped on as shown by the chain line, the transmission ring support member 14 is moved to the right through the spring 15 which is received at the left end by the spring seat 13. The gear ratio R = (rotation speed of the output shaft / rotation speed of the input shaft) increases when the transmission ring is moved toward the apex of the conical surface of the four-cone rotor 3 and decreases when moved toward the bottom. Therefore, the rightward movement of the speed change ring support member 14 is the movement toward the high speed side of the speed change ring 4, but the amount of movement is the spring at that time.
It depends on the length of 15 (compressed state). When traveling resistance is large and load torque applied to the speed change ring 4 is large, such as when traveling uphill, since the thrust generated by the cam device 10 is large, the length of the spring 15 is small, and conversely, when traveling on a flat ground,
When the running resistance is small and the load torque applied to the transmission ring 4 is small, the thrust generated by the cam device 10 is small, so
The length of the spring 15 is large. Spring according to running resistance
The above-mentioned control by the accelerator pedal, which is carried out while changing the length of 15, allows the vehicle to be operated under a gear ratio in which the condition and the slope of the road surface are taken into consideration.
