Description
Technical field
The present invention relates to a kind of Synchromous device of gearbox, especially a kind of Synchromous device of gearbox that is applied to transport on the lorry.
Background technique
The automobile gearbox synchronizer mainly contains two kinds of lockpin-type or lock ring types.Lock ring type synchronizer synchronizing tooth ring and the synchronous engage a gear of soldered tooth conical surface friction pair, owing in the process of gearshift that runs up, under the condition of high temperature, rub for a long time between synchronizing ring and the cone, cause the premature wear of conical surface easily, make it become easily damaged parts, increased the use maintenance cost.
Summary of the invention
The invention provides a kind of Synchromous device of gearbox, it is improved to the base steel material structure with the inside and outside synchronous conical ring of former copper-based material, and on inside and outside synchronous conical ring surface of friction pair bonding carbon fiber, make it more wear-resistant, high temperature resistant, prevent from effectively to ablate and early stage wearing and tearing, improve the usability of product, prolonged the working life of product.
The present invention has adopted following technological scheme: a kind of Synchromous device of gearbox, and it comprises tooth hub, tooth cover and friction system, described tooth cover is enclosed within on the tooth hub, is provided with spline in the described tooth hub; Described friction system is made up of soldered tooth and synchronizing ring, described synchronizing ring is made up of external conical shape ring that matches and inner conical ring, be provided with the location tapered collar in the described inside and outside tapered collar, described inside and outside tapered collar and location tapered collar surface of friction pair are provided with carbon fiber, and described synchronizing ring connects with positioning hole on the soldered tooth by the location tapered collar; Be provided with spline in the described soldered tooth, be with gear on described spline, the spline respectively, two gears are taken out connection by two.
Described tooth hub and tooth cover adopt lock ring type flywheel sychronising structure; The material of described tooth hub, tooth cover, soldered tooth, external conical shape synchronizing ring and inner conical synchronizing ring is an alloyed steel.
The present invention has following beneficial effect: a kind of Synchromous device of gearbox structural type of the present invention adopts lock ring type tooth hub, tooth cover to cooperate, and manufacturability is strong.Friction system setting synchronously has friction torque and increases, and has quick, light, the fuel-efficient characteristics of gearshift.Particularly, make it more wear-resistant at the bonding carbon fiber of inside and outside conical ring conical friction secondary surface, high temperature resistant, have friction factor steady in a long-term, the friction torque of its generation also just is in long-term stability, prevents from effectively to ablate, improve the usability of product, prolonged product working life.The synchronizing ring material selection improves, and saves cost.
