Description

Locomotive clutch and its cover

The present invention relates to a clutch and an outer cover thereof, and more particularly to a clutch applied to a locomotive and an outer cover thereof.

The locomotive is characterized by maneuverability, speed, convenience and convenient parking. It is suitable as a short-distance travel tool, so the locomotive has become the most common means of transportation in China.

The general locomotive uses the action of the clutch to dominate the separation and engagement of the engine running power, while the clutch is rotated by the engine to drive the belt, and the belt clutches the clutch to rotate, which drives the turbulence block of the outer circumference of the clutch seat due to the centrifugal force. While swinging outward, the friction plate on the outer side of the smashing block contacts the clutch cover to rotate.

However, the inner wall of the conventional clutch cover is mostly smooth. When the output torque of the engine is greater than the friction between the clutch cover and the friction plate, or the frictional resistance of the friction plate is reduced, the friction plate and the clutch are not only caused. The outer cover forms a slip and idling, and the high temperature is generated due to the sliding contact, thereby shortening the service life of the clutch and affecting the efficiency of the locomotive operation.

At present, the clutch-related industry has an oblique, wavy or various irregular ring pattern on the inner circumference of the outer cover to increase the friction between the outer cover and the friction plate. However, the friction plate is in the process of just coming into contact with the fully clamped outer cover, or During the process of gradual release, the oblique direction of the clutch cover, the undulating zigzag or various irregular annular lines themselves will have lateral component and shear force, which will cause the friction plate to be severely scraped and worn, and the service life is relatively reduced. Therefore, how to solve the above problems is the subject of research that the relevant industry players are eager to study.

The purpose of the present invention is to provide a locomotive clutch and an outer cover thereof, which are provided with a plurality of pointed and convex ring strips on the inner circumferential surface of the outer cover, so that the respective concave and concave ring grooves of the piece are fully contacted against the opposite tip. The convex ring strips form a more effective frictional resistance, which can improve the transmission efficiency, and can solve the problems of slipping and idling which occur in the prior art, and improve the wear condition of the sheet to ensure the service life of the sheet. .

In order to achieve the above object, the present invention provides a locomotive clutch cover, comprising an outer cover body having an end wall and a ring wall extending from a peripheral edge of the end wall and surrounding the central axis; the cover The body is concentrically provided with a plurality of pointed ring strips on the inner circumferential surface of the annular wall, each of the pointed loop strips being spaced apart from each other along a central axis, and each of the pointed loop strips is straight and relatively perpendicular to the central axis.

In a preferred embodiment, the end wall of the outer cover body is provided with a shaft hole along the central axis to penetrate a transmission shaft, and the two sides of the plurality of pointed ring strips are respectively connected to each other.

In a preferred embodiment, the plurality of pointed loop strips are each formed in a triangular tooth profile.

Moreover, the present invention provides a locomotive clutch, comprising: an outer cover having an outer cover body having an end wall and a ring wall extending from a peripheral edge of the end wall and surrounding the central axis; a clutch seat inside the outer cover; a plurality of circumferentially spaced apart driving rocker arms disposed on the outer circumference of the clutch seat; the plurality of fixed rockers are fixed in the relative drive The outer side of the arm is a piece; when the clutch seat rotates to drive the driving rocker arms to swing outward, the outer piece is outwardly offset from the inner circumferential surface of the ring wall of the outer cover body; and the outer cover The body is concentrically provided with a plurality of pointed ring strips on the inner circumferential surface of the ring wall, each of the pointed loop strips are arranged along the central axis, and each of the pointed loop strips is straight and relatively perpendicular to the central axis; The outer side of the sheet corresponds to each of the pointed loop strips to form a concave and concave ring groove, so that the respective concave and concave ring grooves of the sheet are fully contacted against the relatively pointed loop strip.
