Abstract
The utility model relates to a copper ring outer-cone synchronizer, belonging to the technical field of an automotive transmission synchronizer and comprising a gear wheel, a gear sleeve, a synchronous ring and a check ring, wherein the gear wheel is provided with a main gear and a joint gear, and the end surface of the joint gear of the gear wheel is provided with three slots uniformly distributed and is provided with an end surface groove. The inner ring of the synchronous ring is provided with three claws uniformly distributed, and the gear sleeve of the synchronizer is installed on the gear hub of the synchronizer by spline. The outer cone surface of the synchronous ring is matched with the inner cone surface of the gear sleeve of the synchronizer, and the check ring of the synchronizer installs the synchronous ring in the conical surface slot of the gear sleeve of the synchronizer by riveting. The three uniformly distributed claws of the inner ring of the synchronous ring are respectively arranged in the three uniformly distributed slots of the joint gear of the gear wheel. A spring of the synchronizer is arranged in the end surface groove of the gear wheel, and the gear wheel check ring stabilizes the spring of the synchronizer in the end surface groove of the gear wheel by riveting. Under the premise that the size of a transmission is not changed, the copper ring outer-cone synchronizer effectively increases synchronous properties, largely reduces shift force, reduces the labor intension of a driver, makes shift smooth, has good hand feeling, and is especially suitable for motorcycle types of cars, MPV, SUV, and the like.
Description
Affiliated technical field
The utility model relates to a kind of copper ring outer cone synchronizer, belongs to automotive transmission synchronizer technical field.
Background technique
Existing armstrong's patent speed changer is provided with synchronizer between each shifting gear of speed changer, gear meshing is not hit during with the assurance gear shift, pay off except the gear shift noise, prolonged the life-span of gear, make gearshift procedure light, rapid, thereby help improving the power character and the fuel economy of automobile.Along with the development with rapid changepl. never-ending changes and improvements of speed changer technology, the small volume speed changer bears the feature that high pulling torque has become the high technology content speed changer, but the increase of moment of torsion will certainly influence shift property, the situation that occurs gear engagement inefficacy even broken teeth in the speed changer working procedure, cause the speed changer operational failure, make driving have potential safety hazard.
Summary of the invention
In order to overcome the deficiency of existing synchronizer, of the present utility modelly provide a kind of copper ring outer cone synchronizer, guaranteeing increases synchronization diameter under identical space, can obtain bigger synchronising torque under the situation of same single conical surface, make gearshift procedure more light, rapid, smooth-going, good hand touch.Structure of the present invention also has production technology simple, the advantage that can reduce production costs greatly.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of copper ring outer cone synchronizer, comprise gear, tooth cover, synchronizing ring, back-up ring, and gear has main tooth, soldered tooth, and gear engagement increment face has three uniform grooves, and the end face groove is arranged on the end face; The synchronizing ring inner ring has three uniform claws; Synchronizer gear sleeve is installed on the synchromesh gear hub by spline; The male cone (strobilus masculinus) of synchronizing ring matches with the inner conical surface of synchronizer gear sleeve, and the synchronizer back-up ring is installed in synchronizing ring in the conical surface groove of synchronizer gear sleeve by riveted joint, and three uniform claws of synchronizing ring inner ring are respectively charged in three uniform grooves of gear engagement increment face; Synchronizer spring is contained in the end face groove of gear, and the gear back-up ring is stabilized in synchronizer spring in the end face groove of gear by riveted joint.
Beneficial effect of the present invention: owing to adopted three conical surface synchronizers, cone of friction is increased to three by of conventional synchronizer, synchronising torque is strengthened greatly, thereby shortened lock in time, widened the synchronizer operating range, under the prerequisite that does not change transmission dimensions, effectively improved net synchronization capability, alleviate berth-changing strength greatly, reduced driver's labor intensity, made gear shift smooth-going, good hand touch is specially adapted to vehicles such as car, MPV, SUV.
Below in conjunction with the drawings and specific embodiments the present invention is described further.
