Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If hybrid motorization systems are implemented in cargo and passenger vehicles, then fuel economy and emission reduction are improved, but system complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the combustion engine and electric motor into a single integrated power transmission set that shares common components such as the gearbox, clutch, and transmission housing. This merging approach enables hybrid functionality while reducing overall system complexity compared to separate engine systems.
Solution Approach 2:
The power transmission set is designed to perform multiple functions: it can operate in combustion-only mode, electric-only mode, or hybrid mode, and can also function as a generator. The same physical components serve different purposes depending on the operating mode, reducing the need for dedicated components for each function.

AI summary
The present invention refers to a power transmission set for tractioned axles of vehicles applied, particularly in vehicles with hybrid motorization systems whose characteristics were designed and developed to provide effective control of working conditions, being fully electric, fully combustion, hybrid or even acting as an electric generator. More particularly, the present invention refers to a power transmission set which is comprised of a primary axle (10) and a secondary axle (12), which are interconnected by a selector unit (11) responsible for selecting and controlling the type of motor propulsion applied to the tread axle (R) of said vehicle (V), and, cooperatively with coupling/uncoupling devices (30, 40), it becomes possible to obtain a configuration in which only the combustion engine (MC) is responsible for propulsion; only the electric motor (ME) provides propulsion, in which both engines (MC, ME) work together to generate torque; or, also, the uncoupling of the traction of the tread axle (R) so as to feed the electric motor (ME) that becomes an electric power generator. The present invention also refers to a vehicle for the transport of cargo and passengers comprising the present power transmission set.
