摘要： A continuously variable transmission (CVT) system for use on snowmobiles, ATV's and similar vehicles. The CVT includes a rotatable drive clutch connected to an input shaft (the input shaft being connectable to an engine), and a roller clutch carried on the input shaft. The CVT also includes a rotatable driven clutch connected to an output shaft, the driven clutch having a laterally stationary sheave and a laterally movable sheave that is normally biased toward the stationary sheave. An endless flexible drive belt is disposed about the drive and driven clutches. The clutches and drive belt are configured so that when the engine is idling the belt firmly engages a drive surface of the roller clutch that is connected to the drive clutch. The roller clutch permits the drive surface (and, therefore, the belt) to remain stationary when the input shaft is rotating, thereby preventing vehicle "creep" when idling, and, yet, the roller clutch also firmly engages the drive clutch's drive surface with the input shaft when the driven clutch attempts to drive the belt faster than the speed at which the drive clutch and input shaft are rotating, thereby permitting the driven clutch to backdrive the input shaft and engine to provide engine braking to the vehicle.

摘要： A torque-responsive clutch has an output shaft and an output pulley mounted with respect to the shaft. The output pulley includes a first sheave fixed with respect to the shaft and a second sheave axially movable with respect to the shaft. A helix is mounted with respect to the shaft. In the improvement, a roller container is mounted for driven engagement with the shaft and such container has an interior surface with a plurality of helix-contacting devices, e.g., rollers, mounted adjacent thereto. The helix extends into the container and contacts the devices. In other aspects of the improved clutch, the roller container and the second sheave define a chamber and the helix-contacting devices are confined in such chamber.

摘要： Improved safety and operation is obtained in a high-speed variable ratio pulley having a movable pulley flange which is driven rotatively by torque transmitting engagement between fixed spider arms and drive posts adjacent the periphery of the movable pulley flange, and is thrust axially toward a fixed pulley flange by centrifugal cam levers acting between the movable pulley flange and the spider arms. The drive posts closely straddle the thrust line and are long enough to give clearance for the intended flange movement, and their ends are tied together by a tie plate and a ductile bell housing which also engage an outboard bearing to support the posts and movable pulley flange against tilting. Cam movement of the pulley flange is limited, in one case by providing the cam levers with hooked ends which stop their swing at a point short of thrusting the movable pulley flange into forceful abutment with the fixed pulley flange, and in another case by positioning the tie plate to move as a stop against the ends of the spider, substantially on the cam thrust line. For special applications, the spider is adjustably positioned to provide different cam locations and engaging speeds.

摘要： A controller for a continuously variable transmission includes an electronic control unit. The electronic control unit reduces a change in a target speed ratio of the continuously variable transmission when a sensitivity coefficient is large as compared to when the sensitivity coefficient is small. When the sensitivity coefficient is large, a change in speed ratio is suppressed, so the stability of the speed ratio is improved. When the sensitivity coefficient is small, the response of a shift is improved. The controller changes a degree of suppressing a shift of the continuously variable transmission in response to the sensitivity coefficient, so it is possible to suppress a shift where necessary. Thus, it is possible to achieve both improvement in the stability of the speed ratio and improvement in the response of a shift in automatic vehicle speed control. This suppresses a feeling of strangeness experienced by a driver.
摘要翻译：用于无级变速器的控制器包括电子控制单元。当灵敏度系数较小时，电子控制单元减小无级变速器的目标速度比的变化。当灵敏度系数大时，速度比的变化被抑制，因此提高了速比的稳定性。当灵敏度系数小时，转移的响应得到改善。控制器响应于灵敏度系数而改变抑制无级变速器的变速的程度，因此可以抑制必要的变速。因此，可以实现速比的稳定性的提高和自动车速控制的变速的响应的提高。这样就抑制了司机经历的陌生感。

摘要： A rotation ratio of a continuously variable transmission for a vehicle provided with a pair of variable pulleys whereof the diameter of a contact part with a V-belt is made to vary according to an oil pressure, is controlled according to the running state of a vehicle. An oil pressure control valve is therefore provided to control the oil pressure. A rotation ratio command value is computed from a target rotation ratio set according to the vehicle running state and a control variable set for each rotation ratio according to the dynamic characteristics of the transmission. By inputting a signal based on this rotation ratio command value to the oil pressure control valve, a desirable speed change response is obtained.

摘要： This invention relates to a variable ratio transmission system suitable for vehicles in which the speed regulator is mounted on the transmission driven shaft, and the relationship governing its response to the speed variation of the driven shaft is such as to induce a transmission ratio variation to predetermine the speed of the system input shaft, which is intended for connection to the drive shaft. Means are also provided for connection to engine regulator means, in order to determine the constant speed of the system input shaft as a function of the torque applied to the transmission input shaft.

摘要： A torque transmission system has driving and driven pulley units drivingly connected by an endless V-belt. Each of the driving and driven pulley units includes a stationary pulley rotatable with a shaft and a movable pulley disposed to define with the stationary pulley a circumferential continuous groove for receiving the V-belt. The movable pulleys of the driving and driven pulley units are axially resiliently biased so that the radii of the circles along which the V-belt engages the driving and driven pulley units are varied to change the speed-change ratio of the transmission system. The movable pulley of the driven pulley unit is axially shifted by fly weights. The driving and driven pulley units are provided with cam mechanisms each comprising a cam member and a follower member. When the load on the driven pulley unit is suddenly varied, the cam mechanisms are operative to keep constant the rotational speed of the driven pulley unit irrespective of variations in the load on the driven pulley unit.
