Abstract
The invention discloses an automobile synchronizer capable of reducing shifting power. The automobile synchronizer comprises a synchronizing conical ring (1) and a synchronized gear (2), wherein the synchronizing conical ring (1) is meshed with the synchronized gear (2), a sliding sleeve (3) is arranged in the inner ring of the synchronizing conical ring (1), the sliding sleeve (3) is in transmission connection with the gear lever of the automobile, the side of the sliding sleeve (3) is in contact with the synchronizing conical ring (1), a sliding block (4) is arranged at the bottom of the sliding sleeve (3), a positioning device is arranged in a positioning slot (7) in the middle of the sliding block (4), the synchronizing conical ring (1) can be pushed to move by the positioning device and the sliding block (4) which are driven by the shifting power generated from poking the sliding sleeve (3) by the gear lever, and the synchronizing conical ring (1) is pressed on the conical surface of the synchronized gear (2). The automobile synchronizer has the capabilities of reducing shift travel, reducing shifting power and lowering noise.
Description
Technical field
The present invention relates to a kind of automobile synchronizer that reduces berth-changing strength.
Background technique
Usually adopt flank of tooth contact location to carry out gear shift carrying out automobile synchronizer at present, but because the stroke during gear shift is big, berth-changing strength is big, so the synchronizer volume ratio is bigger, switching speed is slow, noise is big.
Summary of the invention
The invention provides a kind of automobile synchronizer that reduces berth-changing strength, it not only can reduce the gear shift stroke, reduces gearshift power, and reduces noise.
The present invention has adopted following technological scheme: a kind of automobile synchronizer that reduces berth-changing strength, it is characterized in that it comprises synchronous conical ring and by synchromesh gear, synchronously conical ring with thought engagement by synchromesh gear, in the interior ring of synchronous conical ring, be provided with sliding sleeve, the speed change lever of sliding sleeve and automobile is for being in transmission connection, the side of sliding sleeve contacts with synchronous conical ring, bottom at sliding sleeve is provided with slide block, in the locating slot that the neutral position of slide block is provided with, be provided with positioning device, sliding sleeve generation gearshift power drive positioning device stirred by speed change lever and slide block promotes synchronous conical ring action together, and conical ring is pressed onto by on the conical surface of synchromesh gear synchronously.
Described positioning device comprises spring and place kick, and place kick is positioned at locating slot and contacts with sliding sleeve, spring be positioned at place kick below.
The present invention has following beneficial effect: locating slot of the present invention is positioned at slide block, in locating slot, be provided with positioning device, owing to reduced the height of location and adopted the steel ball location, become some contact by original face contact, so not only can reduce berth-changing strength, reduced the gear shift stroke, and simple in structure, with low cost, easy for operation, flexibly, solved that the Light-duty Vehicle gear shift is slow, noise is big, improved the shift property and the life-span of car load.
