Problems solved by technology

[0004] However, in the conventional technology described above, when the vehicle is stopped and the brake is not operated but the accelerator is operated, it is determined that the driver intends to start, and the eccentric amount of the eccentric disk of the power transmission unit is increased from zero to a predetermined value. However, there is no way to avoid the fact that a delay occurs before the eccentric amount of the eccentric plate is increased from zero to the specified value by the shift actuator, and therefore, there is a decrease in the responsiveness of the vehicle to start possibility of

Embodiment Construction

[0043] Below, based on Figure 1 to Figure 10 Embodiments of the present invention will be described.

[0044] Such as Figure 1 ~ Figure 3 As shown, the power transmission device for a vehicle that transmits the driving force of the engine E to the drive wheels W, W via left and right axle shafts 10 , 10 includes a crank type continuously variable transmission T and a differential D. The continuously variable transmission T of the present embodiment is formed by superimposing a plurality of (four in the embodiment) power transmission units U having the same structure in the axial direction. These power transmission units U have a common input and are arranged in parallel. The shaft 11 and the common output shaft 12, the rotation of the input shaft 11 is transmitted to the output shaft 12 after being decelerated or accelerated.

[0045] Next, based on Figure 2 ~ Figure 6 The structure of the continuously variable transmission T will be described.

[0046]First, the config...

Abstract

The invention provides a power transmission device for a vehicle, which can improve the start response when a vehicle restarts after stop. In the power transmission device for a vehicle with a crank type power transmission unit, if a stop intention detection unit detects the stop intention of a driver in decelerating running of the vehicle, a start resistance calculating unit calculates the start resistance of the vehicle and an offset control unit controls the offset of an eccentric disc in a range of greater than zero and less than a value generating an output torque basically equal to the start resistance in a period from the detection of the stop intention to the detection of the start intention of the driver by a start intention detection unit. Thus, while the stop state of the vehicle is maintained, the offset can be increased in advance, and the delay for increase of the offset to a necessary value is reduced at the moment of vehicle start, so that the start response is improved. The offset is increased from the decelerating running of the vehicle, so that even the vehicle is restarted after being just stopped, the start response is improved.

Description

technical field [0001] The present invention relates to a power transmission device for a vehicle, wherein a power transmission unit that transmits the rotation of an input shaft connected to a drive source to an output shaft after speed-changing includes: an input-side fulcrum having an eccentricity with respect to the axis of the input shaft Variable, and the input side fulcrum rotates together with the input shaft; one-way clutch, which is connected with the output shaft; output side fulcrum, which is arranged on the outer part of the one-way clutch; connecting rod, which makes Both ends are connected to the input-side fulcrum and the output-side fulcrum to reciprocate; and a speed change actuator for changing the eccentricity of the input-side fulcrum. Background technique [0002] In a power transmission device for a vehicle including this crank type power transmission unit, a device is known according to the following Patent Document 1: when the vehicle is stopped and ...
