Embodiment Construction

[0046] Embodiments in the present disclosure will be described with reference to the drawings. In the figures, identical or similar components have the same reference numerals. In addition, some of the components illustrated in one or more figures may be omitted in other figures, eg, for illustrative purposes. Also, the scale reductions in the drawings may not be exact.

[0047] The torque limiter in the present disclosure is installed, for example, at a vehicle employing a part-time four-wheel drive system in which the vehicle runs in the front-wheel drive mode under normal conditions and in optional condition in Driving in four-wheel drive mode. The torque limiter of the present disclosure can also be applied to vehicles employing any drive system, including, for example, front-wheel drive systems (i.e., front-engine front-wheel-drive layout (FF) vehicles), rear-wheel drive systems (i.e., Front-engine rear-wheel drive (FR) vehicles, mid-engine rear-wheel drive (MR) vehicl...

Abstract

The invention provides a torque limiter(90) comprising a first meshing portion(52) provided at a surface of an input shaft(50), a plate(200;200A; 200B) including a second meshing portion(210;210A;210B) which is configured to mesh with the first meshing portion(52), and a disc spring portion(120) integrally rotatable with an output shaft(20), the disc spring portion(120) including an engaging portion(130,135) engaging with the plate(200;200A; 200B), the disc spring portion(120) deflected to displace the engaging portion(130,135) in a direction opposite to the plate in a case where a load equalto or greater than a set value is applied to the disc spring portion(120) while pressing the plate(200;200A; 200B) via the engaging portion so as to bias the second meshing portion(210; 210A;210B) towards the first meshing portion(52).

Description

technical field [0001] The present disclosure generally relates to torque limiters. Background technique [0002] A known torque limiter incorporated in a differential gear unit is disclosed in JP2014-052048A (hereinafter referred to as Patent Reference 1). The torque limiter disclosed in Patent Reference 1 includes a first rotation member, a second rotation member, and a pressing mechanism, which are arranged in a rotatable manner around the axis of a drive shaft. set in the differential case. The first rotating member is integrally rotated with the differential case by the output of the transmission. The second rotation member faces the first rotation member and is arranged coaxially with the first rotation member to be engageable with the first rotation member. The urging mechanism is provided adjacent to the first rotation member and generates urging force in a circumferential direction of the urging mechanism by a spring. [0003] The first rotation member includes,...
