Abstract
A power transmission system includes an input shaft, a toroidal CVT arranged on the input shaft, a countershaft arranged parallel with the input shaft for transferring power output from the CVT to wheels, a power distributing device for distributing power from the countershaft to the front and rear wheels, a first casing for defining a first compartment accommodating the CVT, a second casing disposed adjacent to the first casing and for defining a second compartment accommodating the power distributing device, a separation wall arranged between the first compartment and the second compartment and for sealing the compartments in a fluid-tight manner, and first and second oils charged in the first and second compartments and having different characteristics.

A power transmission system for a motor vehicle with an engine and front and rear wheels, comprising:
- an input shaft which inputs power from the engine;
- a toroidal CVT arranged on the input shaft, the CVT being able to continuously convert power from the input shaft;
- a countershaft arranged parallel with the input shaft, the countershaft transferring power output from the CVT to the wheels;
- a power distributing device which distributes power from the countershaft to the front and rear wheels;
- a first casing which defines a first compartment, the first compartment accommodating the CVT;
- a second casing disposed adjacent to the first casing and defining a second compartment, the second compartment accommodating the power distributing device;
- a separation wall arranged between the first compartment and the second compartment, the separation wall sealing the compartments in a fluid-tight manner;
- and
- first and second oils charged in the first and second compartments, the first and second oils having different characteristics.
A motor vehicle, comprising:
- an engine;
- front and rear wheels;
- and
- a power transmission system linked to the engine and the front and rear wheels, the power transmission system comprising:
- an input shaft which inputs power from the engine;
- a toroidal CVT arranged on the input shaft, the CVT being able to continuously convert power from the input shaft;
- a countershaft arranged parallel with the input shaft, the countershaft transferring power output from the CVT to the wheels;
- a power distributing device which distributes power from the countershaft to the front and rear wheels;
- a first casing which defines a first compartment, the first compartment accommodating the CVT;
- a second casing disposed adjacent to the first casing and defining a second compartment, the second compartment accommodating the power distributing device;
- a separation wall arranged between the first compartment and the second compartment, the separation wall sealing the compartments in a fluid-tight manner;
- and
- first and second oils charged in the first and second compartments, the first and second oils having different characteristics.
