US 6,804,897 B1 · Apparatus and method for use in assembling drive train of a race car

Abstract

Apparatus for use in aligning the differential input shaft of a race car with the transmission output shaft includes a transmission attachment and a differential attachment, each of which is detachably mountable to the race car. Each attachment includes a laser mounted centrally in a plate which is mounted substantially perpendicular to the transmission and the differential respectively. The laser mounted to the transmission emits a light beam coaxial to the transmission output shaft and the laser mounted to the differential emits a light beam coaxial to the differential input shaft. By adjusting the differential and transmission relative to each other such that the laser beams do not intersect, the differential and the transmission are aligned for optimum performance. A camber gauge may be substituted for the laser in either plate to measure the attitude of the differential or the transmission.

Apparatus to align an input shaft of a differential gear of a rear wheel drive vehicle with an output shaft of a transmission thereof, comprising

a first attachment detachably mounted to a one of the input shaft of the differential gear and the output shaft of the transmission,
a second attachment detachably mounted to an other of the input shaft of the differential gear and the output shaft of the transmission,
the first attachment comprising a laser selectively emitting a first light beam toward the second attachment,
the first light beam coaxial with the one of the input shaft and the output shaft to which the first attachment is detachably mounted,
the second attachment comprising a target element having a region thereof aligned with the axis of the other of the input shaft and the output shaft to which the second attachment is detachably mounted,
the target element intersecting the first light beam when the input shaft of the differential gear is generally aligned with the output shaft of the transmission.
