Problems solved by technology

[0006] However, as the number of shift stages of the transmission increases, the number of internal components making up the transmission also increases
This leads to undesirable effects such as a decrease in the mountability and transmission efficiency of the transmission and an increase in the cost and weight of the transmission

Embodiment Construction

[0015] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application or use. It should be understood that throughout the drawings, corresponding reference numerals indicate like corresponding parts and features.

[0016] The present disclosure relates to a multi-speed transmission for a vehicle.

[0017] refer to figure 1 with figure 2 , a multi-stage transmission for a vehicle according to one form of the present disclosure may include: an input shaft "IN"; an output shaft "OUT"; disposed between the input shaft "IN" and the output shaft "OUT" to transmit rotational force The first planetary gear device "PG1", the second planetary gear device "G2", the third planetary gear device "PG3" and the fourth planetary gear device "PG4", the planetary gear devices "PG1", "PG2", "PG3 ” and “PG4” each have three rotating elements; and at least six shift elements (for example, clutches CL1-CL6), connected to the rotating elem...

Abstract

The present disclosure relates to a multi-stage transmission for a vehicle that includes four planetary gear devices and six shifting elements, and each of the planetary gear devices include three rotary elements selectively connected to the six shifting elements, preferably so that the multi-stage transmission provides at least ten forward shifting stages and at least one reverse shifting stage with a relatively small number of parts and a simple configuration. In this configuration, an engine may be operated at desired operation points, to improve the fuel efficiency of the vehicle and improve the quietness of the vehicle.

Description

technical field [0001] The present disclosure generally relates to a multi-stage transmission for a vehicle. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0003] The recent rise in oil prices has driven automakers around the world into an intense race to improve fuel efficiency. In addition, great efforts have been made to reduce the weight and improve the fuel efficiency of the engine based on various technologies such as downsizing and the like. [0004] Another method for improving fuel efficiency is to use a multi-speed transmission to allow the engine to operate at more efficient operating points. [0005] In addition, the multiple stages of the transmission allow the engine to operate in a relatively low RPM (revolutions per minute) range, thereby improving the quietness of the vehicle. [0006] However, as the number of shift stages of the tran...
