A centrifugal clutch is configured so that assist thrust can be maintained constant or can be decreased even when a clutch shoe is abraded. The centrifugal clutch includes a drive plate to be rotatably driven by drive force of an engine. The drive plate includes each of swing support pins and the plate-side cam bodies. The swing support pin is fitted in a long-hole-shaped pin slide hole formed at a clutch weight to swingably support the clutch weight. The plate-side cam body includes a cylindrical roller, and a weight-side cam body of the clutch weight contacts the plate-side cam body. The weight-side cam body is formed as such a curved surface that a cam angle when a clutch shoe contacts a cylindrical surface of a clutch outer is the same between before and after abrasion of the clutch shoe progresses.

An engine including an engine block having a cylinder defining a front of the engine, a blower housing coupled to the engine block and defining a hot half and a cool half opposite the front half, a starter mount assembly coupled to the blower housing and positioned within the cool half, an electric starter motor retained by the starter mount assembly, and a battery mounted to the blower housing and positioned in the cool half. The battery is electrically coupled to the electric starter motor.

Described herein is a system, method of use and Self Retracting Lifeline (SRL) apparatus using a system that governs a dynamic response between members causing a halt in relative motion between the members. Magnetic interactions, eddy current drag forces and centrifugal and/or inertial forces may provide various mechanisms of governing movement.

A pump group for a cooling system of an engine of a vehicle, of the dual type is provided. The pump group includes an impeller mounted on a shaft commandable in rotation by an electric drive and a mechanical drive. The mechanical drive includes a rotating member commandable in rotation by mechanical movement devices in the vehicle, a rotary drum operatively connected to the shaft, a centrifugal clutch device including a central body integrally attached to the rotating member and a plurality of engagement elements movably fixed on the central body suitable to translate in a radial direction with respect to the axis (X-X) to engage the rotary drum.

Provided is a centrifugal clutch configured so that assist thrust can be maintained constant or can be decreased even when a clutch shoe is abraded. The centrifugal clutch 200 includes a drive plate 210 to be rotatably driven by drive force of an engine. The drive plate 210 includes each of swing support pins 214 and the plate-side cam bodies 218. The swing support pin 214 is fitted in a long-hole-shaped pin slide hole 231 formed at a clutch weight 230 to swingably support the clutch weight 230. The plate-side cam body 218 includes a cylindrical roller, and a weight-side cam body 235 of the clutch weight 230 contacts the plate-side cam body 218. The weight-side cam body 235 is formed as such a curved surface that a cam angle when a clutch shoe 233 contacts a cylindrical surface of a clutch outer 240 is the same between before and after abrasion of the clutch shoe 233 progresses.

Provided is a centrifugal clutch configured so that a clutch weight can be smoothly displaced without interference with backward displacement of the clutch weight in a rotary drive direction of a drive plate and assist thrust can be stably generated. A centrifugal clutch 200 includes, through swing support pins 214, clutch weights 230 on a drive plate 210 to be rotatably driven by drive force of an engine, and includes plate-side cam bodies 218 and dampers 221. The clutch weight 230 turnably displaces to a clutch outer 240 side through the swing support pin 214, and includes a weight-side cam body 235 configured to climb on the plate-side cam body 218 and a damper groove 236. The damper groove 236 is formed such that a groove width W2 for fitting the damper 221 when the clutch weight 230 is at a clutch-ON position is wider to a front side in a rotary drive direction of the drive plate 210 than a groove width W1 for fitting the damper 221 when the clutch weight 230 is at a clutch-OFF position.

A centrifugal clutch that can suppress the inclination of a clutch weight, realize smooth oscillation, and suppress the uneven wear of a clutch shoe is provided. A drive plate (210) slidably supports a clutch weight (230) and also supports a projection body (218) via a projection body support pin (216). The clutch weight (230) includes a first spring attachment part (231) and a second spring attachment part (234) to which two clutch springs (235) are attached formed, and a driven part (238) that comes into contact with the projection body (218) formed. The projection body (218) and the driven part (238) are formed in a manner that a projection body range (TE) where the projection body (218) and the driven part (238) come into contact overlaps action positions (FP1) and (FP2) of forces (F1) and (F2) of the clutch spring (235) acting on the clutch weight (230) in the thickness direction of the clutch weight (230).

Provided is a centrifugal clutch configured so that tilt of a clutch weight can be more effectively reduced to reduce occurrence of uneven wear of the clutch weight and a clutch shoe and smoothly swing the clutch weight. A centrifugal clutch 200 includes clutch weights 230 and plate-side cam bodies 218 on a drive plate 210 to be rotatably driven by drive force of an engine. The clutch weight 230 turnably displaces to a clutch outer 240 side, and includes a weight-side cam body 238 configured to climb on the plate-side cam body 218. In the clutch weight 230, each of a center portion CCP in a cam contact area CE between the plate-side cam body 218 and the weight-side cam body 238, the positions FP1, FP2 of action of force F1, F2 of a coupling spring 235, and a center portion SCP of a clutch shoe 236 in a thickness direction thereof is coincident with a barycentric position WCP of the clutch weight 230.

The present invention relates to a centrifugal clutch (100). The centrifugal clutch (100) includes a drive plate (110) that is rotationally driven directly by the driving force of the engine. The drive plate (110) includes a swing support pin (113) that supports a clutch shoe (123) in a swinging state with respect to a clutch outer part (130), and a spring support (115) that supports a torsion spring (116). The spring support (115) is provided in a standing state on a base (111) adjacent to one distal end (121a) of both end parts of a clutch weight (120) in the circumferential direction that faces a tubular surface (131) of the clutch outer part (130). Both end parts (116b) and (116c) of the torsion spring (116) are respectively hooked on the distal end (121a) of one clutch weight (120) and a proximal end (121b) of the other clutch weight (120) of the two clutch weights (120).
