Problems solved by technology

As a result, swivelability and fuel consumption are adversely affected, and when a four-wheel drive vehicle shifts from a two-wheel drive state to a four-wheel drive state, good clutch operation by the clutch cannot be obtained.
[0014] On the other hand, in order to suppress the adverse effects of the above-mentioned drag torque, it is conceivable, for example, to expand the gap between two adjacent clutch plates among the clutch plates of the main clutch, but in this case, the Reduced responsiveness of clutch action

Abstract

A driving force transmission apparatus (1) includes: a first cam mechanism (15) that converts rotational force from a housing (12) into first cam thrust force (P1) used as clutch force of a main clutch (8) when the first cam mechanism (15) is actuated through clutch action of a pilot clutch (10); and a second cam mechanism (16) that is actuated prior to conversion of the rotational force into the first cam thrust force by the first cam mechanism (15), and that generates second cam thrust force (P2) for reducing an interval between clutch plates of the main clutch (8). The second cam mechanism (16) includes an input cam member (160) that rotates upon receiving rotational force used as actuating force of the input cam member (160) from a cam actuating driving source (5), and an output cam member (161) that generates the second cam thrust force (P2) between the output cam member (161) and the input cam member (160) and outputs the second cam thrust force (P2).

Description

technical field [0001] The present invention relates to a driving force transmission device. Background technique [0002] Japanese Patent Application Laid-Open No. 2003-014001 discloses, as a conventional driving force transmission device, a device that is mounted on, for example, a four-wheel drive vehicle and that couples a pair of rotating members with a clutch so that torque can be transmitted. [0003] This driving force transmission device is configured to include: a first rotating member that rotates together with the input shaft, a second rotating member that is rotatable on the axis of the first rotating member, and the second rotating member and the first rotating member are connected to each other. A friction-type main clutch capable of transmitting torque, an electromagnetic clutch arranged along the axes of the first rotating member and the second rotating member on the main clutch, and a friction-type auxiliary clutch (pilot) driven by receiving the electromag...
