Freewheel of a Vehicle - A simplified explanation of the abstract
This abstract first appeared for US patent application 18542707 titled 'Freewheel of a Vehicle
The abstract of the patent application describes a freewheel mechanism for a vehicle, specifically a two-wheeler, which includes a crankshaft, an output shaft with a first gear cog, a freewheel element with a second gear cog, and a friction element. The gears are designed to transfer torque between the output shaft and the freewheel element. The freewheel element can move axially on the crankshaft and is non-rotatable in the circumferential direction. A helical mechanism connects the freewheel element and the friction element, allowing for translational displacement when they rotate relative to each other.
- The freewheel mechanism is designed for a vehicle, particularly a two-wheeler.
- It includes a crankshaft, an output shaft with a gear cog, a freewheel element with a gear cog, and a friction element.
- The gears transfer torque between the output shaft and the freewheel element.
- The freewheel element can move axially on the crankshaft and is non-rotatable in the circumferential direction.
- A helical mechanism connects the freewheel element and the friction element, enabling translational displacement during rotation.
Potential Applications: - Two-wheeler vehicles - Automotive industry - Mechanical engineering applications
Problems Solved: - Efficient torque transfer - Axial displacement capability - Non-rotatable design
Benefits: - Improved performance - Enhanced durability - Simplified design
Commercial Applications: Title: "Innovative Freewheel Mechanism for Two-Wheelers" This technology can be utilized in the production of two-wheeler vehicles, enhancing their performance and durability. It can also be integrated into various mechanical engineering applications, providing efficient torque transfer solutions.
Questions about the technology: 1. How does the freewheel mechanism improve the performance of two-wheeler vehicles? 2. What are the key advantages of using a helical mechanism in the freewheel design?
Original Abstract Submitted
A freewheel of a vehicle, in particular a two-wheeler, includes (i) a crankshaft, (ii) an output shaft having a first gear cog, (iii) a freewheel element having a second gear cog, and (iv) a friction element. The first gear cog and the second gear cog are configured to, when engaged with each other, effect a torque transfer between the output shaft and the freewheel element. The freewheel element is arranged to be displaceable in an axial direction on the crankshaft. The freewheel element is arranged to be non-rotatable relative to the crankshaft in the circumferential direction. The freewheel element and the friction element are connected to one another by means of a helical mechanism, which is configured to effect a translational displacement of the freewheel element and the friction element relative to one another when the freewheel element and friction element rotate relative to one another.
