Problems solved by technology

However, in the starting device described in Patent Document 1, the radial oil passage portion of the hydraulic oil passage, the radial oil passage portion of the supply oil passage of the lubricating oil passage, and the radial oil passage portion of the return oil passage of the lubricating oil passage are respectively separated. The casing occupies different installation spaces that are separated in the axial direction, so there is a problem that the device grows larger in the axial direction

Embodiment Construction

[0032] Refer below Figure 1 to Figure 8 One embodiment of the starting device embodying the present invention will be described. In addition, in the following description, "front-back direction" refers to figure 1 The anterior-posterior direction indicated by the arrow in the isotype.

[0033] like figure 1 and figure 2As shown, the starting device 11 is a device for transmitting the torque of the output shaft 12 of the engine as the driving source to the input shaft 13 of the transmission mechanism, and is fixed on the front by a front cover 14 connected with the output shaft 12 of the engine and by welding. The pump cover 15 on the outer peripheral side end portion of the cover 14 constitutes a housing 16 as an input side member. Furthermore, the damper device 17 and the starting clutch 18 as a clutch mechanism are accommodated inside the housing 16, and are filled with ATF (automatic transmission fluid) as working oil and lubricating oil so as to be sealed and oil-tig...

Abstract

A starting device includes a housing; an output side member; a clutch mechanism; a working oil passage that supplies working oil to a hydraulic chamber of the clutch mechanism from an oil pressure source side; and a lubricating oil passage including a supply oil passage that supplies lubricating oil to the housing from the oil pressure source side and a return oil passage for returning the lubricating oil to the oil pressure source side from the housing, wherein the working oil passage and the lubricating oil passage are formed to overlap at least partially in an axial direction.

Description

technical field [0001] The invention relates to a starting device in a vehicle with an automatic transmission. Background technique [0002] Generally, for a vehicle with an automatic transmission, a starting device is used to smoothly transmit the torque of the engine to the transmission mechanism when starting. The starting device has an oil-sealed housing (input side member) connected to the output shaft of the engine, and a turbine hub (turbine hub) (output side member) and a clutch mechanism are arranged in the housing, wherein, usually, the turbine hub The input shaft of the speed change mechanism is installed through the spline connection on the top, and the turbine hub is connected to the input shaft so as to be integrally rotatable with the input shaft. The clutch mechanism mechanically connects the turbine hub and the housing through the clutch action to directly connect . [0003] In addition, within the housing, thrust bearings for restricting the axial movemen...
