Abstract

Drivability is improved by generating a maximum engine torque at the time of origination. A lockup clutch (30) for altering a power transmission path is arranged in parallel with the power transmission path between the pump impeller (11) and the turbine runner (13) of a fluid coupling (10) arranged between the drive side and the load side, a stall capacity coefficient Cs¢N m / rpm2! is determined based on an engine r.p.m. generating a maximum engine torque Tmax on the drive side, and used for transmitting rotation on the drive side to the load side. Best accelerability is obtained by setting the stall capacity coefficient Cs such that the stall r.p.m. approaches the r.p.m. for generating a maximum engine torque, drivability is improved by a quantity of control not causing strange feeling between the quantity of stepping an accelerator and the vehicle speed, and the mileage can be enhanced.

Description

technical field [0001] The present invention relates to a fluid transmission device with a lock-up clutch using a fluid joint of an automatic transmission of a vehicle, etc.; more specifically, to a fluid transmission device with a lock-up clutch having a lock-up clutch in the fluid joint . Background technique [0002] Nowadays, automobiles are required to reduce fuel consumption. When looking at the torque converter from the perspective of reducing vehicle fuel consumption, it has the effect of increasing the torque at the start of the vehicle. However, there is still improvement in reducing fuel consumption when driving for a long distance. room for. [0003] Therefore, there is a technology disclosed in Patent Document 1 as a conventional fluid transmission device with a lock-up clutch. Patent Document 1 discloses the following technology, that is, the fluid joint device (1) has: an integral housing (3, 4) connected to the output shaft of the engine (in addition, the n...
