Abstract
Abstract A front engine - front wheel drive automobile having an engine located transversely of the automobile body and a differential gear unit which is sidewardly offset from the longitudinal center line of the automobile body. A left and right drive shafts extend from the differential gear unit to a left and right front wheels and have different lengths so that the drive shafts are inclined with respect to a horizontal plane by different angles. The wheel which is connected with the drive shaft with a larger inclination angle has a larger camber angle than the other wheel. The arrangement is effective to decrease the difference between turning moments about the left and right king pin axes due to the difference in inclination angles of the driving shafts.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
192 words
A front engine - front wheel drive automobile comprising a power unit including differential gear means provided with left and right output shafts, left and right front wheels mounted for steering movement about left and right king pin axes, respectively, left and right drive shafts having one end connected with said left and right output shafts of the differential gear means, respectively, and the other end with said left and right wheels, respectively, to transmit driving torque to the wheels, said left and right drive shafts being inclined with respect to a horizontal plane by different angles so that a difference between turning moments about said left and right king pin axes is produced when the driving torque is being transmitted to the wheels, the wheel which is connected with the drive shaft with a larger inclination angle with respect to the horizontal plane having a larger camber angle than the other wheel to thereby produce a difference between turning moments about the left and right king pin axes which is in a direction opposite to the difference between turning moments caused by the different angles in inclination of the driving shafts.
Claim 2
Dependent Claim
192 words
A front engine - front wheel drive automobile comprising a power unit including differential gear means provided with left and right output shafts, left and right front wheels mounted for steering movement about left and right king pin axes, respectively, left and right drive shafts having one end connected with said left and right output shafts of the differential gear means, respectively, and the other end with said left and right wheels, respectively, to transmit driving torque to the wheels, said left and right drive shafts being inclined with respect to a horizontal plane by different angles so that a difference between turning moments about said left and right king pin axes is produced when the driving torque is being transmitted to the wheels, the wheel which is connected with the drive shaft with a larger inclination angle with respect to the horizontal plane having a larger camber angle than the other wheel to thereby produce a difference between turning moments about the left and right king pin axes which is in a direction opposite to the difference between turning moments caused by the different angles in inclination of the driving shafts.
Claim 3
Dependent Claim
68 words
An automobile in accordance with claim 1 in which said left and right output shafts of the differential gear means are arranged horizontally, said differential gear means being sidewardly offset from a longitudinal center line of the automobile so that the left and right driving shafts have different lengths, said different angles in inclination of the driving shafts being caused by the different lengths of the driving shafts.
Claim 4
Dependent Claim
73 words
An automobile in accordance with claim 1 which includes left and right front wheel suspension means defining said left and right king pin axes, said suspension means being arranged so that the king pin axis for the wheel which is connected with the drive shaft with a larger inclination angle being inclined outwardly as compared with the other king pin axis whereby said wheel has a larger camber angle than the other wheel.
Claim 5
Dependent Claim
104 words
An automobile in accordance with claim 3 in which said left and right suspension means including a left and right oleo strut assemblies, respectively, each of said strut assemblies having an upper end connected with a body of the automobile for a pivotable movement about an upper pivot point and a lower end supporting one of said wheels, a swingable arm having one end vertically swingably connected with said body and the other end supporting the lower end of said strut assembly for a pivotable movement about a lower pivot point, said upper and lower pivot points defining one of said king pin axes.
Claim 6
Dependent Claim
22 words
An automobile in accordance with claim 1 in which said power unit includes an engine which is located transversely on the automobile.
