Background technique
Because transmission input shaft and engine output shaft rotate with respective speed, can there is a synchronous problem during conversion gear, synchronizer will reach consistent rotating speed and engage smoothly by meshed gears.Synchronizer, when top gear drives bottom gear, does not have synchronizer to there will be the very large problem of instant impact, has a strong impact on the working life of part, the problem that existing synchronizer has centrifugal force little, engage not smooth.
Model utility content
For the deficiencies in the prior art, need a kind of synchronizer that can increase centrifugal force.
For realizing above-mentioned technological scheme, the utility model provides a kind of Simple friction type synchronizer, it comprises outer ring, concentric inner ring is provided with in outer ring, inner ring center forms inner splined hole, inner ring bilateral symmetry is provided with control loop support plate, described inner peripheral surface also has several the first waist shaped hole around center of circle array, the medial axis of the first waist shaped hole extends past centre point, described control loop support plate surface has second waist shaped hole corresponding with the first waist shaped hole, the medial axis of the second waist shaped hole and the first waist shaped hole medial axis are an angle, and the aperture of the second waist shaped hole is less than the first waist shaped hole, quality post is all inserted with in the waist shaped hole of described correspondence, quality post is three pitch cylinders, a middle pitch cylinder matches with the first waist shaped hole, its two terminal circle cylinder matches with the second waist shaped hole, the outer rim of inner ring has the roller slip groove identical with the first waist shaped hole quantity, the roller slip groove side that contacts with outer ring is provided with opening, roller is provided with in roller slip groove, spring and roller driving lever, roller driving lever two ends difference sleeve is on the control loop support plate of both sides, roller is close to roller driving lever, spring one end is close to roller, the other end is close to roller slip groove inwall.
Described roller contacts with outer ring inner side surface and roller slip groove inner side surface simultaneously.
Angle between the medial axis of described second waist shaped hole and the first waist shaped hole medial axis is 5 ° ~ 15 °.
Described control loop support plate center has circular hole, and Circularhole diameter is greater than the diameter of inner splined hole.
The quantity of described first waist shaped hole, the second waist shaped hole, roller slip groove is respectively 6 ~ 12.
The beneficial effect that this Simple friction type synchronizer reaches is: the maximum feature of this structure adopts several quality posts to overcome the little problem of centrifugal force; Roller is under the effect overcoming spring force, be close together with outer ring, moment of torsion effectively can be passed to outer ring by inner ring, has angle between the medial axis of the second waist shaped hole and the first waist shaped hole medial axis, only need rotate very little angle and just can reach the object transmitting rotating speed between inner ring and outer ring.
