Abstract
The utility model relates to a gear used synchronizer, more particularly a double cones synchronizer, which solve the problem that in the prior arts a single ring synchronizer has small volume, huge structure and poor reliability. The double cones synchronizer comprises an outer ring, a middle ring and an inner ring from outer to inner, wherein the matching faces between the middle ring and the outer ring, the inner ring are both cone faces, the middle ring is uniformly distributed with six convex claws along the round circle direction which is equipped on six concave dents on the gear end face, and the friction medium material of the synchronizer ring in the technological scheme can be resin, molybdenum and powder metallurgy, suitable for different working conditions. Compared with the prior single ring synchronizer, the utility model has a compact structure and big volume, and can be used to smaller the gear box whole structure, lighten the weight and increase the economic performance.
Description
Technical field
The utility model relates to a kind of gearbox synchronizer, specifically is a kind of double-cone synchronizer.
Background technique
Known, the peripheral velocity of the gear teeth of a pair of gear to be meshed must equate or synchronously in the gearbox, could enter engagement (also being gearing in) smooth-goingly, put into gear if force when the two is asynchronous, to make and take place between two conjunctions to impact and noise, influence the operating life of tooth, can make gear tooth breakage when serious.When solving gear shift, do not produce impact between the gear teeth or the spline in the gearbox, general gearbox all is provided with synchronizer.Existing synchronizer adopts monocycle list conical surface synchronizer usually, and the synchronizer capacity of this kind structure is little, structure is huge, is not suitable for the large-sized speed-changing case and uses.
Summary of the invention
Monocycle synchronizer capacity is little in the prior art, structure is huge, the problem of poor reliability in order to solve for the utility model, provide a kind of realize gearbox whenever can both gear shift, the double-cone synchronizer of compact structure.
The utility model adopts following technological scheme to realize: double-cone synchronizer is made of outer shroud, central ring, interior ring from outside to inside, the fitting surface of central ring and outer shroud, interior ring is all the conical surface, along the circumferential direction be evenly equipped with six dogs on the central ring, be installed in six grooves of gear face, the friction media material of synchronizing ring can be resin, molybdenum and powder metallurgy in the technical program, adapts to different operating modes and uses.
The monocycle synchronizer structure compared compactness of the utility model and prior art, capacity are big, and use can make that the gearbox overall structure diminishes, weight saving, Economy improve.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is working principle of the present utility model and scheme of installation
Among the figure: 1-gear, 2-conical ring, 3-outer shroud, ring in the 4-central ring, 5-, 6-dog, 7-toothholder, 8-tooth cover, 9-axle, 10-shift fork.
Embodiment
Further specify embodiment of the present utility model in conjunction with the accompanying drawings, embodiment is used for illustrating of the present utility model, rather than it is imposed any restrictions.
Double-cone synchronizer is made of outer shroud 3, central ring 4, interior ring 5 from outside to inside, and central ring 4 is all the conical surface with the fitting surface of outer shroud 3, interior ring 5, along the circumferential direction is evenly equipped with some dogs 6 on the central ring 4, and dog 6 is six.Groove fit on dog 6 and the gear conical ring 2.Synchronizer is installed on the toothholder 7, and toothholder 7 is connected in axle 9 by spline, and tooth cover 8 is set on the toothholder 7.When putting into gear, shift fork 10 drives tooth cover 8 left sides or moves right, and tooth cover 8 promotes a double-cone synchronizer left side or moves right, and in the groove that the dog 6 on the central ring 4 inserts on the gear conical ring 2, by the frictional force transferring power, makes the gear that is engaged consistent with engagement cover linear velocity.
Claims (2)
