Abstract
Abstract A belt-type continuously variable transmission in which a drive pulley mounted on an input shaft and a driven pulley mounted on an output shaft are connected by an endless belt, a forward- and backward-movement switchover mechanism for transmitting a driving force from an engine to the drive pulley is disposed adjacent the stationary pulley half of the drive pulley, and a starting clutch for transmitting the rotation of the output shaft to driving wheels is disposed adjacent stationary pulley half of the driven pulley. This ensures that dead spaces created in a section opposed to both the movable pulley halves which move axially can be utilized as spaces for disposition of the forward- and backward-movement switchover mechanism and the starting clutch, thereby enabling the forward- and backward-movement switchover mechanism and the starting clutch to be disposed in a compact layout.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
A belt-type continuously variable transmission for a vehicle with an engine and driving wheels comprising an input shaft connected to the engine and driven by the engine; an output shaft disposed in parallel to said input shaft and connected to the driving wheels; a drive pulley comprised of a stationary pulley half and a movable pulley half which are carried on said input shaft; a driven pulley comprised of a stationary pulley half and a movable pulley half which are carried on said output shaft; and an endless belt connecting said drive pulley and said driven pulley to each other, said stationary and movable pulley halves of said pulleys being arranged in a diagonal relationship with one another, wherein said transmission further includes a forward- and backward-movement switchover mechanism disposed adjacent the stationary pulley half of the drive pulley on said input shaft for transmitting a driving force from the engine to the drive pulley, and a starting clutch disposed adjacent the stationary pulley half of the driven pulley on said output shaft for transmitting the rotation of the output shaft to the driving wheels.
Claim 2
Dependent Claim
185 words
A belt-type continuously variable transmission for a vehicle with an engine and driving wheels comprising an input shaft connected to the engine and driven by the engine; an output shaft disposed in parallel to said input shaft and connected to the driving wheels; a drive pulley comprised of a stationary pulley half and a movable pulley half which are carried on said input shaft; a driven pulley comprised of a stationary pulley half and a movable pulley half which are carried on said output shaft; and an endless belt connecting said drive pulley and said driven pulley to each other, said stationary and movable pulley halves of said pulleys being arranged in a diagonal relationship with one another, wherein said transmission further includes a forward- and backward-movement switchover mechanism disposed adjacent the stationary pulley half of the drive pulley on said input shaft for transmitting a driving force from the engine to the drive pulley, and a starting clutch disposed adjacent the stationary pulley half of the driven pulley on said output shaft for transmitting the rotation of the output shaft to the driving wheels.
Claim 3
Dependent Claim
132 words
A belt-type continuously variable transmission of the type having an input shaft; an output shaft disposed in parallel to the input shaft; a drive pulley on the input shaft having a stationary pulley half and a movable pulley half; a driven pulley on the output shaft having a stationary pulley half and a movable pulley half; and an endless belt connecting said drive pulley and said driven pulley to each other; an improvement comprising a forward- and backward-movement switchover mechanism disposed adjacent the stationary pulley half of the drive pulley on said input shaft for transmitting a driving force from the input shaft to the drive pulley, and a starting clutch disposed adjacent the stationary pulley half of the driven pulley on said output shaft for transmitting rotation from the driven pulley.
Claim 4
Dependent Claim
132 words
A belt-type continuously variable transmission of the type having an input shaft; an output shaft disposed in parallel to the input shaft; a drive pulley on the input shaft having a stationary pulley half and a movable pulley half; a driven pulley on the output shaft having a stationary pulley half and a movable pulley half; and an endless belt connecting said drive pulley and said driven pulley to each other; an improvement comprising a forward- and backward-movement switchover mechanism disposed adjacent the stationary pulley half of the drive pulley on said input shaft for transmitting a driving force from the input shaft to the drive pulley, and a starting clutch disposed adjacent the stationary pulley half of the driven pulley on said output shaft for transmitting rotation from the driven pulley.
Claim 5
Dependent Claim
27 words
The transmission of claim 1 or 2, wherein the forward- and backward-movement switchover mechanism includes a clutch for selectively connecting the input shaft to the drive pulley.
Claim 6
Dependent Claim
29 words
The transmission of claim 1 or 2, wherein the forward- and backward-movement switchover mechanism is positioned in a space radically opposite the movable pulley half of the driven pulley.
Claim 7
Dependent Claim
26 words
The transmission of claim 1 or 2, wherein the staring clutch is positioned on a space radially opposite the movable pulley half of the drive pulley.
