The small set 8022 was released in 1993 and was one of the smallest Universal Set to date. It includes full instructions for 4 models. There a number of parts left over when any of the models are built.
This set was marketed as a Technic starter set, a role which it fulfils aptly. None of the models are complex, but all show off various possibilities of the Technic line. This set is also the only universal set to ever come in white and is therefore an excellent source of those rare white beams. The parts selection is otherwise unremarkable.
I find the Airplane the most interesting, and it is the model I chose to keep assembled for my display of this set.
1st Model: Airplane
This little airplane spins the 2-blade propellor when the main landing gear is rolled. As can be seen in the computer image, the main landing gear axle drives a 24 tooth crown through an 8 tooth pinion. This gear reduction is then reversed through a second 8 tooth pinion, and then further reversed with a final stage at the propellor. This results in a final ratio of 3:1
2nd Model: Truck
This small truck features front wheel steering and a ratcheted hook at the rear.
The front wheels can be steered using an overhead wheel. The wheel drives an 8 tooth pinion gear. The pinion drives the steering rack. The steering mechanism itself uses the flexible steering rack and steering arms.
The hook on the rear can be lifted via a ratchet mechanism. The input crank is actually a connector part. When this is rotated, a set of 8 and 24 tooth spur gears is turned. The larger spur mates with a pawl which rest against it and prevents it from being turned backward. A second stage of gears results in a total reduction of 9:1.
3rd Model: Robot
To date, the various attempts at Technic robots had been pretty gimpy. Sadly, this one did nothing to change that trend.
The robot sits on a tricycle of wheels. The front wheels can be steered using a rear wheel hub. The wheel drives an 8 tooth pinion gear. The pinion drives the steering rack. The steering mechanism itself uses the flexible steering rack and steering arms.
The central rear wheel turns an axle with a 24 tooth spur gear at one end. One of the offset holes in the gear is used to create a crank. This crank drives a link which attaches to another crank on the robot's left arm. Osciallation of the crank makes the arms wave up and down. Additionally, the arm axle is linked to the neck through a set of 8 and 24 tooth gears. So when the robot is pushed, the arms move and the head turns back and forth.
The steering function is not linked with the other functions.
4th Model: Racer
This small racer features front wheel steering and nothing else.
The front wheels can be steered using a wheel at the driver's position. The wheel drives an 8 tooth pinion gear. The pinion drives the steering rack. The steering mechanism itself uses the flexible steering rack and steering arms.
