Vehicle system with prime mover, torque converter, and direct drive unit
A recently granted patent (Publication Number: US11885413B2) discloses a system for a vehicle that includes a prime mover capable of coupling to a transmission via a torque converter and a direct drive unit. The direct drive unit consists of a higher range clutch and a lower range clutch, along with directional clutches and range clutches. These components are strategically positioned to optimize the vehicle's performance and efficiency. Additionally, a controller is integrated into the system to manage the connection between the prime mover and the transmission based on specific conditions, such as vehicle start and speed variances, ensuring smooth operation and power distribution.
Furthermore, the patent also covers a transmission system that features an engine selectively connecting to a transmission through a torque converter and a direct drive unit. Similar to the vehicle system, this transmission system includes directional clutches, range clutches, and a controller to facilitate the optimal engagement of the engine with the transmission. The controller is programmed to disengage the torque converter under certain conditions and activate the appropriate clutches in the direct drive unit to maintain efficient power transfer. By incorporating these innovative components and control mechanisms, the patented transmission system aims to enhance overall performance and responsiveness, particularly in scenarios where precise power management is crucial for vehicle operation.
