Problems solved by technology

[0005] However, as the number of gears in the transmission increases, the number of internal components that make up the transmission also increases
This can lead to undesirable effects such as reduced mountability and transmission efficiency, and increased transmission cost and weight

Abstract

The present disclosure is a multi-stage transmission for a vehicle that has at least ten forward shifting stages and one reverse shifting stage. The multi-stage transmission has a relatively small number of parts and a simple configuration such that an engine may be operated at desired operation, thereby providing an improvement in the fuel efficiency of the vehicle. ,Moreover, the engine may be operated more quietly, thereby improving the quietness of the vehicle.

Description

technical field [0001] The present invention generally relates to multi-speed transmissions for vehicles. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] Recent increases in oil prices have driven global vehicle manufacturers into the race to improve fuel efficiency. In addition, great efforts have been made to reduce weight and improve fuel efficiency of engines based on various techniques such as downsizing, and the like. [0004] Meanwhile, among methods of improving fuel efficiency using a transmission equipped in a vehicle, there is a method of enabling an engine to operate at a more efficient operating point using a multi-stage transmission, thereby improving fuel efficiency and enabling the engine to operate at a relatively low to run in the revolutions per minute (RPM) range. [0005] However, as the number of gears of the transmission in...
