Abstract
The utility model relates to a symmetrical locked loop type secondary box synchronizer, which comprises a gear hub, a plurality of pins arranged inside the gear hub, a sliding gear sleeve which is sleeved at the end part of the gear hub, and a slider which is arranged between the gear hub and the sliding gear sleeve. The slider is sleeved on an outer end part of the pins; both the slider and the sliding gear sleeve are axially symmetrical relative to a central axis of the gear hub; and the outer end part of the pins passes through the center of the slider. Because the sliding gear sleeve and the slider of the utility model are in symmetrical structures, the synchronizer does not need to identify the mounting direction, has convenient installation, and is hardly wrong.
Description
Technical field
The utility model belongs to automobile making class field, is specifically related to a kind of symmetric type lock ring type odd-side synchronizer in the gearbox.
Background technique
Most of in the market odd-sides all are to adopt asymmetric structure with the sliding gear collar of lock ring type synchronizer, this asymmetric structure has caused very big difficulty to assembling, has increased working strength of workers, has reduced efficiency of assembling, simultaneously, cause loading error easily.
Summary of the invention
The purpose of this utility model is to solve the deficiency described in the background technique, a kind of more reasonable structure is provided, uses more reliable symmetric type lock ring type odd-side synchronizer.
The technical solution of the utility model is as follows:
A kind of symmetric type lock ring type odd-side synchronizer, comprise the tooth hub, be arranged on a plurality of pins in the tooth hub and be set in tooth hub end sliding gear collar, be arranged on the slide block between tooth hub and the sliding gear collar, slide block set is located on the outer end of pin, its special way is, described slide block and sliding gear collar are all axially symmetrical about tooth hub medial axis, and the outer end of described pin is positioned at the center of slide block.
Above-mentioned synchronizer also includes low gear side outer conical ring of friction and the interior conical ring of low gear side friction that is arranged on tooth hub one side, and conical ring all embeds the tooth hub in described low gear side outer conical ring of friction and the friction of low gear side.
Because sliding gear collar of the present utility model and slide block are the bilateral symmetry structure, need not to distinguish installation direction, easy for installation, be difficult for makeing mistakes, conical ring all embeds the tooth hub in low gear side outer conical ring of friction simultaneously of the present utility model and the friction of low gear side, directly drive conical ring rotation in low gear side outer conical ring of friction and the friction of low gear side by the tooth hub, changed and traditional driven the indirect drive mode that the low gear side outer conical ring of friction and the interior conical ring of low gear side friction rotate respectively, further guaranteed the synchronism of lock ring type odd-side synchronizer by conical ring in high gear side outer conical ring of friction and the friction of high gear side.
