Accessory drive

Claim 2

In a motor vehicle having an engine compartment; an engine in said compartment having a crankshaft extending transversely across the longitudinal axis of the vehicle, said engine having a first end and a second end which are spaced along an axis about which said crankshaft is rotatable; a transmission mounted within said engine compartment at said second end of said engine; an accessory disposed in said engine compartment above said transmission and adjacent said second end of said engine; an accessory drive shaft mounted on said engine, at the upper portion thereof, and having one end projecting beyond said first end of said engine and an opposite end projecting beyond said second end of said engine; a rotary drive connection between said one end of said accessory drive shaft and said crank shaft; and a rotary drive connection between said opposite end of said accessory drive shaft and said accessory.

Claim 3

A motor vehicle as claimed in claim 1 in which said accessory drive shaft is mounted externally of said engine and supported thereon by means of brackets provided with bearings.

Claim 4

A motor vehicle as claimed in claim 1 in which said accessory drive shaft is rotatably journalled within a hollow cam shaft of said engine.

Claim 5

In a motor vehicle having an engine compartment; an engine in said compartment having a cylinder head and a crankshaft, said crankshaft extending transversely across the longitudinal axis of said vehicle, said engine having a first end and a second end which are spaced along an axis about which said crankshaft is rotatable; a transmission mounted at said second end of said engine and operatively connected to said crankshaft; an accessory drive shaft disposed externally of said engine and journalled in bearings mounted on said cylinder head, said accessory drive shaft having a first end which projects beyond said first end of said engine and a second end which projects beyond said second end of said engine; an accessory disposed in said engine compartment above said transmission and adjacent said second end of said engine; a first pulley disposed at said first end of said engine and connected to said crankshaft for unitary rotation therewith; a second pulley fixedly mounted on said first end of said accessory drive shaft; a first drive belt drivingly interconnecting said first pulley and said second pulley; a third pulley fixedly mounted on said second end of said accessory drive shaft; a fourth pulley mounted on said accessory and drivingly connected thereto; and a second drive belt drivingly interconnecting said third pulley and said fourth pulley.

Claim 6

In a motor vehicle having an engine compartment; an engine in said compartment having a cylinder head and a crankshaft, said crankshaft extending transversely across the longitudinal axis of said vehicle, said engine having a first end and a second end which are spaced along an axis about which said crankshaft is rotatable; a transmission mounted at said second end of said engine and operatively connected to said crankshaft; an accessory drive shaft disposed externally of said engine and journalled in bearings mounted on said cylinder head, said accessory drive shaft having a first end which projects beyond said first end of said engine and a second end which projects beyond said second end of said engine; an accessory disposed in said engine compartment above said transmission and adjacent said second end of said engine; a first pulley disposed at said first end of said engine and connected to said crankshaft for unitary rotation therewith; a second pulley fixedly mounted on said first end of said accessory drive shaft; a first drive belt drivingly interconnecting said first pulley and said second pulley; a third pulley fixedly mounted on said second end of said accessory drive shaft; a fourth pulley mounted on said accessory and drivingly connected thereto; and a second drive belt drivingly interconnecting said third pulley and said fourth pulley.

Claim 7

In a motor vehicle having an engine compartment; an engine in said compartment having a cylinder head and a crankshaft, said crankshaft extending transversely across the longitudinal axis of said vehicle, said engine having a first end and a second end which are spaced along an axis about which said crankshaft is rotatable, said cylinder head having a cam shaft operatively disposed therein, said cam shaft being formed with a longitudinally extending coaxial through-bore; a transmisson mounted at said second end of said engine in said compartment and operatively connected to said crankshaft; an accessory drive shaft journalled in said through-bore, said accessory drive shaft having a first end which projects beyond said first end of said engine and a second end which projects beyond said second end of said engine; an accessory disposed in said engine compartment above said transmission and adjacent said second end of said engine; a first pulley disposed at said first end of said engine and connected to said crankshaft for unitary rotation therewith; a second pulley fixedly mounted on said first end of said accessory drive shaft; a first drive belt drivingly interconnecting said first pulley and said second pulley; a third pulley fixedly mounted on said second end of said accessory drive shaft; a fourth pulley mounted on said accessory and operatively connected thereto; and a second drive belt drivingly interconnecting said third pulley and said fourth pulley.

Claim 8

In a motor vehicle having an engine compartment; an engine in said compartment having a cylinder head and a crankshaft, said crankshaft extending transversely across the longitudinal axis of said vehicle, said engine having a first end and a second end which are spaced along an axis about which said crankshaft is rotatable, said cylinder head having a cam shaft operatively disposed therein, said cam shaft being formed with a longitudinally extending coaxial through-bore; a transmisson mounted at said second end of said engine in said compartment and operatively connected to said crankshaft; an accessory drive shaft journalled in said through-bore, said accessory drive shaft having a first end which projects beyond said first end of said engine and a second end which projects beyond said second end of said engine; an accessory disposed in said engine compartment above said transmission and adjacent said second end of said engine; a first pulley disposed at said first end of said engine and connected to said crankshaft for unitary rotation therewith; a second pulley fixedly mounted on said first end of said accessory drive shaft; a first drive belt drivingly interconnecting said first pulley and said second pulley; a third pulley fixedly mounted on said second end of said accessory drive shaft; a fourth pulley mounted on said accessory and operatively connected thereto; and a second drive belt drivingly interconnecting said third pulley and said fourth pulley.
