Parallel hybrid system with electric motor for vehicle

A hybrid drive system for a utility vehicle comprising:

• an electrical power source;
• an electric motor having an output shaft and a connector configured to alternatively receive power from or convey power to the electrical power source;
• a clutch mechanism having a ratchet that is joined to and rotates with the output shaft at a first rotational speed and at least one pawl that is joined to and rotates with a pulley at a second rotational speed;
• and
• an internal combustion engine that connects to and selectively drives rotation of the pulley;
• wherein, when the pulley rotates at a predetermined second rotational speed, the at least one pawl pivots about a pivot pin causing the at least one pawl to contact the ratchet;
• and
• wherein, if the at least one pawl is contacting the ratchet and the second rotational speed matches the first rotational speed, the output shaft is then driven by the internal combustion engine.

A hybrid drive system for a utility vehicle comprising:

• an electrical power source;
• an electric motor comprising an output shaft;
• a connector configured to alternatively convey power to the electric motor from the electric power source or convey power from the electric motor to the electrical power source;
• a housing containing the electric motor, the housing positioned below a pulley and mounted to a mounting deck having a receiving hole through which the output shaft extends, the housing comprising:
• a motor end cap mounted to the mounting deck;
• and
• a motor stator housing that extends through the receiving hole;
• a clutch bearing comprising:
• an inner race that is joined to and rotates with the output shaft;
• and
• an outer race that is joined to and rotates with the pulley;
• and
• an internal combustion engine that connects to the pulley via a belt.
