Driving disc type isolator

Abstract

The utility model relates to an automobile part, in particular to a driving disc type isolator which comprises a flower sleeve, a clamping piece, a cover cap, a gear, a graphite bushing, a baffle, a driving disc, a pin roller, a flat spring, a paper pad and a clamping spring. The small end of the gear penetrates through the flower sleeve, and the flat spring and the pin roller are sealed in a space formed by the flower sleeve and the small end of the gear. The clamping sheet is clamped in the groove of the gear; the paper pad is sleeved at the large end of the flower sleeve; the small end of the flower sleeve is also provided with a shaft shoulder and a clamp spring groove; the baffle is mounted on a shaft shoulder of the flower sleeve; the driving disc is mounted between the two baffles; and the clamp spring is arranged in the clamp spring groove of the flower sleeve. The one-way clutch has the advantages that the driving disc and the shifting fork are in transition connection at the tail of the one-way clutch, original line contact is changed into surface contact, the one-way clutch can be driven out stably, and the problems that top teeth of the one-way clutch cannot be normally meshed with a flywheel gear ring, noise is large and the like can be effectively solved.

Description

Technical Field

[0001] This utility model relates to an automotive component, specifically a drive disc type one-way valve. Background Technology

[0002] One-way clutches are common automotive components. During operation, the shift fork extends the one-way clutch, causing it to rotate at high speed and engage with the engine flywheel. Over time, wear and tear can lead to problems such as the shift teeth failing to properly engage with the flywheel ring gear, excessive noise, and shift fork failure. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a drive disc type one-way actuator.

[0004] The technical solution adopted in this utility model is:

[0005] The drive disc type one-way actuator includes a sleeve, a card, a cover, a gear, a graphite bushing, a baffle, a drive disc, rollers, a flat spring, a paper pad, and a retaining ring. There are multiple flat springs and rollers. The sleeve has evenly distributed curved surfaces along its inner circumference. The flat springs are fixed to the inner curved surfaces of the sleeve, and the rollers press against the flat springs. The small end of the gear passes through the sleeve, enclosing the flat springs and rollers in the space formed by the sleeve and the small end of the gear. The small end of the gear has a groove. The card is inserted into the groove of the gear, axially enclosing the flat springs and rollers. The paper pad is fitted onto the large end of the sleeve, fixing the card. The graphite bushing is installed in the inner hole of the gear. The small end of the sleeve also has a shoulder and a retaining ring groove. There are two baffles, installed end-to-end on the shoulder of the sleeve. The drive disc is installed between the two baffles. The retaining ring is installed in the retaining ring groove of the sleeve to fix the two baffles.

[0006] The beneficial effects of this utility model are: the use of a drive disc and a shift fork at the tail of the one-way valve to transition the connection from the original line contact to surface contact, which makes the one-way valve stable and can effectively reduce problems such as the one-way valve top teeth not being able to mesh properly with the flywheel ring gear and excessive noise, thereby improving the product's service life.
