Abstract

Abstract An automotive vehicle includes a body with an engine compartment. Its power train includes: an engine (E) with a crank shaft (9) and at least one cylinder (8), mounted within the engine compartment with the crank shaft extending transversely to the length of the vehicle body and with the cylinder extending generally horizontally; transmission means (12) with a power input shaft (13), coupled to the engine with the power input shaft substantially coaxial with and rotationally driven from the engine crank shaft; and a differential device (17), driven from the transmission means, with an axial center line which is located substantially vertically below the center line (20) of the crank shaft. Thereby, the engine compartment can be made compact and low in height, and further the moments of inertia of the vehicle about its yaw and pitch axes can be kept low.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 109 words
In an automotive vehicle comprising a body having an engine compartment, a power train comprising: (a) an engine, comprising a crank shaft and at least one cylinder, mounted in said engine compartment with said crank shaft extending transversely of the length of the vehicle body and with said cylinder extending substantially horizontally; (b) transmission means including a power input shaft coupled to said engine, said power input shaft being substantially coaxial with and rotationally driven from said engine crank shaft; and (c) a differential device driven from said transmission means, the axial center line of said differential device being located generally below the center line of said crank shaft.
Claim 2
Dependent Claim 109 words
In an automotive vehicle comprising a body having an engine compartment, a power train comprising: (a) an engine, comprising a crank shaft and at least one cylinder, mounted in said engine compartment with said crank shaft extending transversely of the length of the vehicle body and with said cylinder extending substantially horizontally; (b) transmission means including a power input shaft coupled to said engine, said power input shaft being substantially coaxial with and rotationally driven from said engine crank shaft; and (c) a differential device driven from said transmission means, the axial center line of said differential device being located generally below the center line of said crank shaft.
Claim 3
Dependent Claim 60 words
A power train as claimed in claim 1, wherein said vehicle has two wheels driven from said differential device and arranged on a driven axle, and wherein, in the direction of the length of the vehicle, the said driven axle is located generally between said center line of the crank shaft and said axial center line of the differential device.
Claim 4
Dependent Claim 35 words
A power train as claimed in claim 1 or 2, wherein said differential device has two power output shafts substantially coaxial with each other and with the said axial center line of the differential device.
Claim 5
Dependent Claim 27 words
A power train as claimed in any of claims 1 to 3, further comprising a carburetor mounted p to the said engine generally above said cylinder thereof.
