Title:
トランスミッションの同期装置用のスライドスリーブおよび当該スライドスリーブを備える同期装置
Document Type and Number:
Japanese Patent JP6976272
Kind Code:
B2
Abstract:
Synchronizing units are used in transmissions of vehicles in order to bring a shaft and a gear wheel to an identical rotational speed and, after this synchronization, to couple the shaft and the gear wheel for conjoint rotation. The aim of the present invention is to propose a sliding sleeve having improved functional characteristics and to propose a corresponding synchronizing device or dog clutch having the sliding sleeve. This aim is achieved by means of a sliding sleeve (6) for a synchronizing device (1) or dog clutch of a transmission, wherein the sliding sleeve (6) is designed as an annular body and defines a main axis (H), wherein pitch positions (T) are defined on the annular body, wherein the pitch positions (T) are distributed regularly around the main axis (H) with the spacing of a pitch (t), with a plurality of engagement teeth (12), wherein the engagement teeth (12) are designed as internal teeth, wherein each of the engagement teeth (12) is arranged in a pitch position (T), wherein the sliding sleeve (6) has at least one engagement region (14), in which at least two engagement teeth (12) are arranged in pitch positions (T) which are adjacent in the circumferential direction, with at least one limiting tooth (13) for limiting axial motion of the sliding sleeve (6), wherein the limiting tooth (13), at least in some regions, is arranged in a gap between two pitch positions (T), wherein the tooth profile in a sectional plane extending through the limiting tooth (13) preferably centrally with respect to an axial direction is identical in the case of the limiting tooth (13) and in the case of at least one of the engagement teeth (12).
