Abstract
A lateral force-measuring device for a wheel is directed to a rotator axially installed with universal function for moving in an axial direction and is dependently rotated by a rotation of a pressed wheel, and a load-measuring device measuring a moving load for an axial direction of a rotator when a rotator is rotated. A vehicle inspecting system incorporating a lateral-measuring device for a wheel thereon is provided.
Claims10
A lateral force-measuring device for a wheel comprising;
- a rotator in frictional contact with the wheel, said rotator being operable to move in an axial direction when dependently rotated by a rotation of the wheel;
- a load-measuring device attached to a dog, the load-measuring device being operable to measure a moving load in an axial direction of said rotator when said rotator is rotated by the rotation of the wheel, wherein the moving load can be either of both a tensile load and a compression load;
- and
- a wheel-driving device operable to rotate said wheel, wherein the wheel driving device comprises a throb motor operable to stably control the rotation of said wheel and prevent excessive force from being exerted on the wheel.

A lateral force-measuring method comprising:
- pressing a wheel surface to a rotator;
- connecting a wheel driving device to the wheel;
- stably rotating the wheel by controllably rotating the wheel driving device;
- and
- measuring a lateral force exerted by the rotating wheel on the rotator by determining an amount of compression or tension exerted on a dog connected to the rotator;
- wherein the rotator includes an angular shaft portion disposed inside of a roller, and being roller anchored to the inside of the roller, said bearing rollers contacting the angular shaft portion to facilitate axial movement of the roller along a longitudinal axis of the angular shaft portion, so that said rotator is capable of moving in the axial direction.

A lateral force-measuring method comprising;
- pressing a wheel surface of both of two axially connected wheels to a single rotator;
- pressing a wheel driving device to at least one the wheels;
- stably rotating the wheels by controllably rotating the wheel driving device, and;
- measuring a lateral force exerted by the rotating wheels on the rotator by determining an amount of compression or tension exerted on a dog connected to the rotator;
- bearing rollers anchored to the inside of the roller, said bearing rollers contacting the angular shaft portion to facilitate axial movement of the along a longitudinal axis of the angular shaft portion, so that said rotator is capable of moving in the axial direction.
