The John Deere PowerShift transmission was an eight-speed semi-automatic transmission without a torque converter, used in John Deere tractors, including the iconic John Deere Model 4020. [1] The Powershift is not to be confused with similar John Deere transmissions (including the Quad-Range and the PowrQuad [ 2 ] ), or with the Ford Ultra ...
A semi-automatic transmission is a multiple-speed transmission where part of its operation is automated (typically the actuation of the clutch), but the driver's input is still required to launch the vehicle from a standstill and to manually change gears.
The curve representing a clamped parts-to-bolt stiffness ratio of 0.01 shows that when the relative stiffness of the clamped parts is very low, almost all of the load is transferred to the bolt, down to the point where a compressive load equals the preload, and separation at the bolt head occurs, reducing the force in the bolt to zero.
A skid-steer loader can sometimes be used in place of a large excavator by digging a hole from the inside. This is especially true for digging swimming pools in a back yard where a large excavator cannot fit. The skid loader first digs a ramp leading to the edge of the desired excavation. It then uses the ramp to carry material out of the hole.
A cone clutch serves the same purpose as a disk or plate clutch; however, instead of mating two spinning disks, the cone clutch uses two conical surfaces to transmit torque by friction. [1] The cone clutch transfers a higher torque than plate or disk clutches of the same size due to the wedging action and increased surface area.
In clutch-brake differential steering, power is disconnected to one side or the other with a clutch, and the unpowered side may also have a brake applied to tighten the turn. [1] Note that there is no differential gearset in this design. The tracks on either side of the vehicle will always turn at the same speed unless one is declutched for ...
