The wheel runway apparatus 10 includes a support structure 12. The support structure 12 includes a top surface 14 for supporting a vehicle, and for the embodiment illustrated, but not limited to, supporting the wheels of the vehicle. The support structure 12 includes first and second ends 16, 18, and a length extending between the first and second ends 16, 18 defining a longitudinal direction 20. The support structure 12 further includes inner and outer sides 22, 24, and a width extending between the inner and outer sides 22, 24 defining a lateral direction 26.
The wheel runway apparatus 10 includes at least one lighting module 32. The lighting module 32 is mounted to the top surface 14 of the support structure 12. For the embodiment illustrated, but not limited to that, the lighting module 32 can be mounted generally flush relative to the top surface 14 of the support structure 12. The lighting module 32 can extend adjacent the inner side 22 of the support structure 12. The lighting module 32 is configured to illuminate the vehicle when the vehicle is parked on the wheel runway apparatus 10, for example, but not limited to illuminating an underside region of the vehicle. The lighting module 32 is configured to provide illumination directed generally upwards towards parts of the vehicle that require servicing, and generally not in the mechanic's eyes. The lighting module can also be used for display lighting when the vehicle is on the lift.
In a vehicle wheel alignment lift system, the lighting module 32 can be disposed adjacent a movable support surface of the wheel runway apparatus to provide illumination during wheel alignment procedures.
In some examples, when implemented in a vehicle wheel alignment system, the wheel runway apparatus 10 can include a first movable support surface 28. The first movable support surface 28 can be located towards the first end 16 of the support structure 12, and can be referred to as a “slip plate.” The first movable support surface 28 can be a generally rectangular plate mounted on a bearing surface (not shown), generally flush with the top surface 14 of the support structure 12. The first movable support surface 28 can permit limited motion of the fixed or rear wheels of the vehicle in a horizontal plane, at least in the lateral direction 26, relative to the support structure 12.
In some examples, when implemented in a vehicle wheel alignment system, the wheel runway apparatus 10 can include a second movable support surface 30. The second movable support surface 30 can be located towards the second end 18 of the support structure 12, and can be referred to as a “turn plate” or a “turntable.” The second movable support surface 30 can be a generally round plate mounted on a bearing surface (not shown), generally flush with the top surface 14 of the support structure 12. The second movable support surface 30 can permit the steered or front wheels of a vehicle to be steered from side to side without requiring lifting of the vehicle, and simultaneously permit rotational motion and limited motion in a horizontal plane, in the longitudinal and lateral directions, 20, 26, relative to the support structure 12.
In some examples, the lighting module 32 includes an assembly or plurality of light emitting diodes. The light emitting diodes can be high intensity and low voltage. The light emitting diodes can provide better lighting of the work area and may increase reliability of lighting. Furthermore, use of an assembly or plurality of light emitting diodes may reduce or substantially eliminate shadow effects in the work area. In some examples the lighting module 32 can also include fiber optics. Further combinations of fiber optics and light emitting diodes can be provided for some applications.

The lighting module 32a can be pivotally mounted, either to the support structure 12 or the first movable support surface 28, so that the lighting module 32a is pivotable generally about the longitudinal direction 20. Pivoting allows the illumination provided by the lighting module 32a to be directed as desired by the mechanic. In some examples, referring to

The second movable support surface 30 can include a turn plate 38 movably mounted to a base 40. The base 40 can include a front side 42, a rear side 44, an inner side 46, an outer side 48, and a top surface 50. The front side 42 can be oriented towards the first end 16 of the support structure 12, and the rear side 44 can be oriented towards the second end 18 of the support structure 12 (see
As illustrated, two of the lighting modules 32b, 32c can be mounted to the top surface 50 of the base 40. The lighting module 32b can be mounted adjacent to the front and inner sides 42, 46. The lighting module 32c can be mounted adjacent to the rear and inner sides 44, 46. The lighting modules 32b, 32c can be mounted generally flush relative to the top surface 50 of the base 40, and integrated therein. Positioned in spaced apart locations, the lighting modules 32b, 32c can provide generally complete illumination of the steered wheels as they are rotated from side to side during wheel alignment procedures.
Referring to
The lighting module 32c can include a protective outer cover 56, which can be a rigid transparent or translucent member, for example, a scratch-resistant plastic lens. The protective outer cover 56 can be generally flush relative to the top surface 50 of the base 40, and retained by screws 58. The lighting module 32c can include a sealing ring 60 disposed between the recess portion 52 of the base 40 and the protective outer cover 56.
Alternatively, the protective outer cover can consist of a potting compound (not shown), which can be applied to embed the assembly of light emitting diodes 54 and retain it in the recess portion 52 of the base 40. The potting compound can be selected to have relatively high transparency and scratch resistance, once hardened/cured.
The lighting module 32 can be remotely controlled. For example, the lighting module 32 can be selectively activated through a switch or control provided on the main lift system console (not shown). Alternatively or additionally, the lighting module 32 can be selectively activated through a switch provided on the lift system itself, whether on the support structure 12 or another area that is readily accessible by the mechanic.
The lighting module 32 may also be subject to automatic shutoff. Referring to
