An improved wheel alignment turntable for supporting a wheel of a vehicle. Embodiments include a turntable having a base, and a top plate for receiving the vehicle wheel, the top plate being mounted to an upper surface of the base for rotational and translational movement relative to the base. A pair of paddles, removably adjustably attachable to the base, engages a peripheral wall of the top plate for maintaining the top plate in a predetermined position relative to the base while the vehicle wheel is being positioned on the turntable. The paddles are easily removable when the wheel is supported on the turntable. A plurality of slide pads are removably mounted to a lower surface of the base, for enabling sliding motion between the turntable and a surface of a lift without damaging paint on the surface of the lift. The slide pads are stackable against one another for adjusting height of the turntable relative to the lift.

Turntable for wheel alignment

A common platform is used in conjunction with a host computer to control various equipment sensors that perform different functions. In one aspect, the common platform is a micro-controller board, the host computer is a personal computer (PC), and the equipment sensors comprise an add-on card and a sensor for use in automotive services. A universal serial bus (USB) or an RS232 interface used for the common platform communicates with the host computer and with the equipment sensors. The common platform is a plug and play board that, once attached to the host computer, operates with little or no human intervention. The common platform is capable of accommodating various equipment sensors that are run by various appropriate application software. Further, the common platform can run under different operation power sources. In one aspect, these power sources include a power source embedded in the common platform, an RS232 power source, and a power source external to the common platform, such as a battery.

Common platform for use in automotive services

A cordless vehicle wheel alignment sensor head with interchangeable batteries includes easy to replace rechargeable batteries, thus eliminating the need for a service call to replace the batteries and allows the operator to swap a nearly depleted battery set with a fully or partially charged battery set. The sensor head includes a battery compartment door which slides upwards without pivoting about or detaching from the sensor head, and allows the batteries to pop out and be replaced. The battery compartment door also includes at least one battery engaging protrusion which presses against the battery at a non-contacting end of the rechargeable battery when the battery compartment door is closed. Accordingly, with the battery compartment door closed, the battery is tightly held in place and pressed into a pair of retractable pins that result in electrically coupling the battery to the sensor circuitry.
