变速器的同步器
Abstract:
本发明涉及一种变速器（10）的同步器（12），其具有：同步体（14），其抗扭地安装在变速器轴上；换档接合套（18），其相对于同步体（14）抗扭地但能轴向移动地设置；同步环（22），其用于将同步体（14）与变速器（10）的档位齿轮通过摩擦连接来联接；以及锁止楔同步组件（26），其接合在换档接合套（18）上，并且在换档接合套（18）轴向移动时以轴向的换档力（F）朝向待联接的档位齿轮加载同步环（22），其中，锁止楔同步组件（26）具有同步块（28）和锁止块（30）。在锁止块（30）上构造有贴靠面（56a、56b、58a、58b），这些贴靠面能够接合在同步体（14）的相应的配合面（60a、60b、62a、62b）上，其中，贴靠面和/或配合面（56a、56b、58a、58b、60a、60b、62a、62b）至少在一些区段上地倾斜成，使得在圆周方向（16）上在锁止块（30）和同步体（14）之间作用的力（FR）引起轴向的力分量（FServo），轴向的力分量朝向待联接的档位齿轮加载同步环（22）。
Abstract(English):

The invention relates to a synchronizer (12) for a transmission (10). The synchronizer is provided with: a synchronous body (14) installed on a transmission shaft in an anti-twisting way; a gear shifting joining sleeve (18) disposed in an anti-twisting and axially-moving way relative to the synchronous body (14); a synchronous ring (22) for connecting the synchronous body (14) and a gear toothed wheel of the transmission (10) via friction connection; and locking wedge synchronous component (26) joined on the gear shifting joining sleeve (18), and when the gear shifting joining sleeve (18) is in an axial movement, the synchronous ring (22) is loaded toward the gear toothed wheel to be connected via an axial gear shifting force (F), wherein, the locking wedge synchronous component (26) is provided with a synchronous block (28) and a locking block (30). An attachment surface (56a, 56b, 58a, 58b) is constructed on the synchronous block (28), wherein the attachment surface and/or a cooperating surface (56a, 56b, 58a, 58b, 60a, 60b, 62a, 62b) incline at least in some regions to be in a way that, the force (FR) acting between the locking block (30) and the synchronous body (14) in the circumferential direction (16) causes an axial force component (FServo), and the synchronous ring (22) is loaded toward the gear toothed wheel to be connected via an the axial force component.
