A continuously variable transmission for a vehicle includes a drive clutch, a driven clutch operably coupled to the drive clutch, and a belt extending between the drive and driven clutches. The continuously variable transmission also includes an inner cover and an outer cover removably coupled to the inner cover. At least one of the inner and outer covers includes an air inlet for providing cooling air to the drive and driven clutches and the belt.

A control apparatus of a continuously variable transmission includes a shifting controller and a detector. The continuously variable transmission includes a hydraulic pressure supplier and a continuously variable transmission unit. The continuously variable transmission unit is able to perform continuously variable shifting by a hydraulic pressure in the hydraulic pressure supplier. The shifting controller causes, when the detector detects an abnormality, the hydraulic pressure in the hydraulic pressure supplier to fall within a range that is equal to or greater than a first value and less than a second value. The first value is a value at which minimal operation performed by the continuously variable transmission unit is available. The second value is a value upon normal operation before the detector detects the abnormality.

A continuously variable transmission for a vehicle includes a drive clutch, a driven clutch operably coupled to the drive clutch, and a belt extending between the drive and driven clutches. The continuously variable transmission also includes an inner cover and an outer cover removably coupled to the inner cover. At least one of the inner and outer covers includes an air inlet for providing cooling air to the drive and driven clutches and the belt.

A primary clutch of a continuously variable transmission with a launch mechanism is provided. The primary clutch includes a central post, a fixed sheave assembly, a movable sheave assembly and a locking mechanism. The central post is configured to receive rotational torque from a motor. The fixed sheave assembly is statically mounted on the central post. The movable sheave assembly is mounted on the central post. The movable sheave assembly includes a movable sheave system that is configured to move axially on the central post towards the fixed sheave assembly as RPM of the primary clutch increase. The locking mechanism is configured and arranged to selectively prevent movement of the movable sheave system independent of the RPM of the primary clutch.

The invention relates to the control mechanism developed for continuously variable transmission systems which are chain/belt-driven and which are used in the vehicles with electrical, hybrid and conventional internal combustion engine as an automatic gearbox system in the automotive industry.

A primary clutch assembly for a continuously variable transmission is provided. The primary clutch assembly includes a fixed sheave and a movable sheave centered on a post for joint rotation therewith. A rotational unit disposed on the post generates centrifugal forces during rotation of the post that are translated axially to urge the movable sheave along the post towards the fixed sheave. The primary clutch utilizes an actuator assembly that is configured to establish a locked condition that prevents axial movement of the movable sheave as the rotational unit builds-up centrifugal force and an unlocked condition to allow sudden axial movement of the movable sheave towards the fixed sheave. The actuator assembly includes a bearing unit that extends through a hole in the post to contact the movable sheave in the locked condition and is housed within the hole and spaced from the movable sheave in the unlocked condition.

A transmission assembly for a self-propelled machine includes a transmission housing fitted with an input shaft, an output shaft, a mechanism for reversing the rotational drive direction of the output shaft, and a brake mechanism, each mechanism including a control, the direction reversing and brake controls carried by the housing being mounted respectively movable, one between at least three positions: a neutral, a forward and a reverse position, the other between at least a first braking position and a non-braking position, the brake control being couplable to a brake control member that can be actuated by the operator, in order to shift the brake control from the non-braking to the first braking position. The brake control has a separate second braking position, and the transmission assembly includes return elements capable, in the neutral position of the direction reversing control, of returning the brake control to the second braking position.
