摘要： In an infinitely variable traction roller transmission, wherein two toric traction disks are rotatably supported opposite one another and define a toric cavity in which at least two motion transmitting traction rollers are disposed in engagement with the two toric disks and supported by trunnions, the trunnions being pivotally supported to permit changing the ratio of motion transmission between the toric disks, the toric disks each have a different cavity radius, thus causing the circles of contact of the traction rollers with the toric disk to change as the trunnions pivot to various transmission ratio positions, thereby distributing the loads on the traction rollers over a relatively large surface area thus extending the fatigue life of the traction rollers, and consequently, of the transmission.

摘要： A multimode infinitely variable traction roller transmission including a toroidal traction roller transmission for infinitely varying the transmission ratio in each of the modes. Power is transmitted from an input shaft to the planet carrier of a planetary transmission whose ring is associated with the output shaft of the transmission and through the toroidal traction roller transmission to the sun of the planetary transmission selectively by way of a chain gear or spur gear transmission provided with clutches for selective engagement thereof, that is, for rotation of the sun in one or the opposite direction. A brake structure is provided for locking the planet carrier in one of the transmission modes. Output shaft speed is increased by increasing output speed of the infinitely variable transmission in the first mode (direct mode), it is further increased by subsequently decreasing the output speed of the infinitely variable transmission in the second mode (inverse regeneration mode) and it is then further increased by again increasing the output speed of the infinitely variable transmission in the third mode (split torque mode). The changeover is smooth thereby providing for a wide ratio range infinitely variable transmission.

摘要： A hydraulic speed control arrangement for an infinitely variable transmission which is coupled to an engine and adapted to drive auxiliary equipment including a hydraulic fluid displacement pump includes a spool valve provided with an inlet cavity at one end of the valve spool in the valve body and connected to the hydraulic fluid displacement pump and has a spring disposed at the opposite end and biasing the valve spool against the pressure of the fluid in the inlet cavity, whereby the valve spool is adapted to control the flow of pressurized fluid from the inlet cavity to the transmission ratio control mechanism of the infinitely variable transmission in such a manner that the output shaft speed of the transmission is maintained essentially at a predetermined value. The valve spool had a face portion at its one end provided with a flow orifice structure at its circumference and, further there is a pressuzized fluid cavity disposed adjacent the valve spool face portion so as to control the fluid flow through the orifice structure depending on the position of the face portion which for some applications is in communication with the area of the valve at the other end of the valve spool and the fluid cavity is connected to a pressurized hydraulic fluid user to supply thereto the pressurized fluid needed thereby.

摘要： A traction roller transmission having a number of traction rollers disposed in an annular space formed between a sun roller structure rotatable with one shaft and a traction ring structure surrounding the sun roller. The traction rollers are rotatably supported and the traction rollers or the traction ring structures are mounted for movement with another shaft. At least one of the traction surfaces of the sun roller and the traction ring structures is formed by a sleeve and radially slotted spring washers are disposed behind the sleeve. Cam structures are arranged axially adjacent the spring washers such that a torque transmitted through the transmission forces the spring rings onto said sleeve and said sleeve toward said traction rollers for firm engagement of the traction rollers with the traction ring and the sun roller structures.

摘要： A constant output speed control arrangement for an infinitely variable transmission whose ratio of transmission is controllable by a hydraulic control fluid wherein the transmission output shaft has a fluid displacement pump associated therewith and connected to a control valve structure including a piston disposed in a cylinder and being movable by the control fluid from the pump against the force of a spring with a control passage extending through the piston and a control opening in the cylinder providing communication with a hydraulic ratio control structure in the transmission, the control opening being so arranged relative to the piston that the control opening is closed by the piston when the piston is moved against the spring force by an excess amount of control fluid supplied by the pump so as to cause a transmission ratio change for a decrease of the transmission output shaft, and the control opening is opened by the piston when the piston is returned by the spring for admitting an increased amount of control fluid to the transmission thereby causing an increase in the transmission output shaft speed.
