The present invention relates to a kind of gearbox assembly, especially relate to a kind of combine-harvester four-speed gear shift box assembly.
Background technique
The purposes of gear-box has: acceleration-deceleration is exactly the speed-change gear box of often saying; Change transmission direction, for example we can be with the power vertical transmission to another rotatingshaft with two tooth sector; Change moment of rotation, under the equal power condition, the more fast gear that speed is changeed, a suffered moment is more little, otherwise more big; Clutch function: we can reach the purpose that motor and load are separated by two meshed gears originally separately, such as brake clutch etc.; Distributed power: for example we can be with a motor, drive by the gear-box main shaft a plurality of from axle, thereby realize that a motor drives the function of a plurality of loads.Chinese patent discloses a kind of pinion shaft and differential gear housing assembly, and (notice of authorization number: CN 101563556A), it comprises: differential gear case; Be positioned at the pinion shaft of differential gear case; And the buffer portion in the pinion shaft, buffer portion can contain the part of axletree in order to limit the motion of pinion shaft; Further comprise: a pair of axletree of equal length, it extends into differential gear case, and wherein one of them of axletree is with slow; Middle part engagement is in order to limit the motion of pinion shaft; Wherein do not using under the locking, pinion shaft is fixed to differential gear case; Further comprise: the side gear that is connected to axletree, this side gear is arranged in differential gear case, wherein each axletree extends through side gear, wherein at least one of axletree is in abutting connection with pinion shaft, wherein each axletree can exchange, wherein axletree is the part with vehicle of center line, and further wherein the center line of vehicle be positioned with each axletree equidistant.But this gearbox assembly is when transmission, and synchronism is relatively poor, and combine-harvester is when gearshift, and the conversion of power is slower, thereby has reduced transmission efficiency.
Summary of the invention
The present invention provides a kind of gearbox assembly of tape synchronizer, it mainly is to solve the existing in prior technology gearbox assembly when transmission, and synchronism is relatively poor, and combine-harvester is when gearshift, the conversion of power is slower, thereby reduced the technical problem of transmission efficiency etc.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
The gearbox assembly of tape synchronizer of the present invention, comprise casing, be provided with an axle assembly in the described casing, one axle assembly is connected with clutch assembly, one axle assembly is connected with two axle assemblies, three axle assemblies, differential assembly in turn, differential assembly is connected with left side output brake assembly, right output brake assembly, and two axle assemblies, three axle assemblies are provided with the synchronizer assembly.By the synchronizer assembly, two approaching gear rotating speeds gently excessively can be arrived with speed, thereby make combine-harvester more steady when gearshift, power-converting is very fast.The synchronizer assembly is the commercially available prod, and it is made up of the slippage tooth.Clutch assembly can help gearshift.
As preferably, a described axle assembly includes one, and one is connected with first driving gear, second driving gear.First driving gear can tangle reverse gear, and second driving gear can be used for two of transmissions.
As preferably, described two axle assemblies include two, are connected with two intermediate gears, two three-range transmissions, two shaft transmission gears on two, are provided with the synchronizer assembly between two three-range transmissions and two intermediate gears.When two gear shifts arrived third gear, the synchronizer assembly can be with two steady reductions of speed of three-range transmission, and identical with the speed of two three-range transmissions up to two intermediate gears, the slippage tooth work of synchronizer assembly hangs over gear on the third gear.
As preferably, described three axle assemblies include three, are connected with reverse gear, three one grade of gears, three shaft transmission gears on three, are provided with the synchronizer assembly between reverse gear and three one grade of gears.The synchronizer assembly can transfer to reverse gear and the speed of three one grade of gears identical when gear shift, can steadily switch between reverse gear and three one grade of gears like this.
As preferably, described differential assembly includes differential casing, is provided with cross axle in the differential casing, and cross axle is connected with differential gear by differential gear, differential gear is connected on two semiaxis, and differential assembly connects three axle assemblies by the differential mechanism gearwheel.
As preferably, described left side output brake assembly, right output brake assembly are connected with oil hydraulic cylinder respectively.Brake by oil hydraulic cylinder, make brake weight bigger, and brake is more steady.
As preferably, described three ends are connected with hand brake parts.When running into urgency and need brake, can carry out Emergency braking by hand brake parts.
As preferably, described clutch assembly is connected with the torque dupler assembly.The torque dupler assembly can strengthen the power of an input.
Therefore, the present invention adds two synchronizer assemblies in gear-box inside, makes when combine-harvester switches between reverse gear and one grade, second gear and third gear more steadily, and transmission efficiency is higher, operates comparatively simple, simple and reasonable for structure.
