The present disclosure discloses a method for forming a rim of a cast-spun aluminum alloy hub, that is, a special spinning composite machining method for forming a structure that the spokes and the inner wheel flange of the hub are cast and the middle of the rim is spun. The method can prevent the performance, strength and as-cast structure of the inner wheel flange from being destroyed, effectively improve the impact resistance of the cast-spun hub at the inner wheel flange, prevent the inner wheel flange of the cast-spun hub from cracking during radial impact and improve the performance of the spun structure of the rim, is beneficial to thinning the rim and realizes light weight of the rim.

The present invention provides a novel method for manufacturing a vehicle wheel with a single work piece or band 101. The method comprising the steps of placing a metal band 101 in a mandrel 102 provided at a machining tool; forming the metal band/work piece 101 for making a desired length of rim 201 and a wheel disc 202; spinning a nave portion 401 of the work piece 101 for shaping the wheel disc 202; spinning the work piece 101 for making a disc flange 502 and a gutter portion 504 of the wheel; rolling one end of the rim portion to form the required gutter portion 504 of predetermined shape and thickness; spinning the rim portion further to form a tyre seat and well area 701; forming a flange flare 801 by bending another end of the rim portion; forming the flange portion 901 of the wheel rim by bending the flange flare 801; machining flange edge 1201, nave 1202 and bore; reaming of bolt holes and chamfering bores at the wheel disk portion.

A continuously variable transmission includes: a first pulley having a first fixed sheave and a first movable sheave; a first cylinder forming a first oil chamber with the first movable sheave; a second pulley having a second fixed sheave and a second movable sheave; a second cylinder forming a second oil chamber with the second movable sheave; and a transmission belt wound around the first pulley and the second pulley. The first cylinder has a first member that is fixed to a first shaft and a second member that is joined to an outer peripheral portion of the first member. A bearing is interposed between an outer periphery of the first member and an inner periphery of a case. A thickness, in an axial direction, of a portion of the first member that is configured to directly abut against the first movable sheave is larger than a thickness of the second member.

A method for producing a flywheel includes producing a damping plate part by permanently connecting at least a first metallic plate element provided for the flywheel to at least one further material layer to form a sandwich component. According to the method, the first plate element is connected by a joining process to at least a second, parallel plate layer, so that they lie on one another to form a disc-shaped structural unit. According to the method, at least two sheet metal layers from different materials and/or at least two sheet metal layers having different material strengths are connected with each other. This enables a large variance for the production of flywheels. In this way, it is possible, for example, to produce a flywheel having a plurality of superimposed plates adapted to the respective load situation in a defined flexibility.

The disclosure discloses an automatic wheel detecting device. The device can automatically detect marks of spoke back cavities and the inner side coaxiality and the outer side coaxiality of wheels, the wheels with marks being missed are identified in time, the values of the inner side coaxiality and the outer side coaxiality of the wheels on a production line are monitored in time, if the values are out of tolerance, an alarm is given out in time, and the device can be used for automatic production.
