Problems solved by technology

Therefore, an increase in the number of parts configuring the related art two-speed transmission for an electric vehicle causes a corresponding increase in its manufacturing cost and its weight.
[0006] In addition, since the number of parts configuring the related art two-speed transmission for an electric vehicle increases, and the number of parts that must be controlled increases, the vehicle's acceleration ability, hill climbing ability, and top speed ability deteriorate, and it is disadvantageous The advantage is that the parts configured for the two-speed transmission used in the vehicle are packaged in a predetermined space

Abstract

A two-speed transmission for a vehicle may include a first input shaft, a second input shaft connected to a motor, and a clutch unit for selectively transmitting the power of the motor to an output shaft from the first input shaft and / or the second input shaft. The clutch unit may synchronize rotation speeds of the first input shaft and the second input shaft when the power of the motor is transmitted to the output shaft from the first input shaft.

Description

technical field [0001] The present invention relates to a two-speed transmission for a vehicle, and more particularly, to a two-speed transmission for a vehicle, which can be applied to an electric vehicle or a hybrid vehicle. Background technique [0002] A related art two-speed transmission for an electric vehicle exhibits a high speed level and a low speed level by using clutches and external gears. Figure 1a and Figure 1b is a view showing the layout of a related art two-speed transmission for an electric vehicle. [0003] Such as Figure 1a and Figure 1b As shown, a two-speed transmission applied to a related art electric vehicle includes a friction clutch, an external gear, a one-way clutch, and a lock ring, wherein the friction clutch and the one-way clutch are selectively operated to transmit power through different paths, thereby realizing Low-speed and high-speed stages of a two-speed transmission. Simultaneously, figure 2 is a view showing the layout of a ...
