Abstract
The invention relates to a modularized full-meshed brake type transmission which is composed of planet gear trains with different transmission ratios and a forth and back controller; power transmitted from a motor is controlled by the forth and back controller so as to be output in a positive and negative rotation mode; all downstream planet gear trains are driven simultaneously by the output power; in the downstream planet gear trains, if gear rings are braked and the power is output from a planet frame; and if the gear rings are not braked, and the idling running is carried out. Through controlling the braking of the gear rings in the planet gear trains with different transmission ratios, the transmission purpose of variable moment and variable speed is achieved.
Description
Technical field
The present invention relates to a kind of mechanical variable speed device, especially can be applicable to motor vehicle and Tank and Armoured Vehicle.
Background technique
At present, known manual transmission mainly is nested in gear on each, synchronizer assembly, shift fork, first, second, jack shaft, reverse gear by each gear and operating-controlling mechanism is formed.During operation, personnel control the shift fork position, and shift fork drives synchronizer, make 2 gear engagement that need pairing.During gear shift operation, need the cooperation of clutch, operation is comparatively complicated and loaded down with trivial details.Personnel labor intensity is bigger.
At present, known automatic transmission mainly is made up of fluid torque converter, many gears of planetary pinion multi-change speed mechanism and operating-controlling mechanism.The action of gear shift is carried out, and transfers to computer and fluid torque converter compounding practice.Its automaticity height is easily simple during personnel operation.But, because the existence of fluid torque converter causes its transmission efficiency low, especially under the complex road condition condition, inefficient transmission and problem that the fuel consumption that causes raises is outstanding especially.
Summary of the invention
In order to overcome the deficiency separately that existing manual transmission and automatic transmission exist, the invention provides a kind of modularization speed variator system, it can reach the high efficiency of the full engaging gear transmission of conventional manual speed changer, has exempted the clutch component of conventional truck again.As set up automatic electric chemical control member made, it just becomes automatic speed-changing system.Owing to do not need the intervention of fluid torque converter, therefore do not have the phenomenon that transmission efficiency obviously reduces.
The technical solution adopted for the present invention to solve the technical problems is: have epicyclic trains at different levels to constitute independent gear stage.And just constituting-moveing backward selection mechanism by a planet train of gearings.Power is just reaching-is moveing backward selection mechanism after the motor input.When planet carrier in this mechanism and gear ring locking, be forward gears; When planet carrier and gearbox case locking, then be reverse gear.
Advance and the power of moveing backward, the gear ring output of this mechanism is all arranged, via bridge gear shaft, the variable speed planetary gear of power being delivered to simultaneously each different drive ratios in downstream drives its each sun gear in being.The epicyclic train of each different drive ratios of downstream has constituted the different gear of vehicle.The power of speed changer is then exported by planet carrier.The planetary pinion of different drive ratios at different levels, its planet carrier is rigidly connected with transmission output shaft respectively, and coaxial arrangement.
After the gear ring of the epicyclic train of certain concrete gear was braked, the planet carrier of this grade epicyclic train was with regard to output power.And simultaneously, the gear ring of the epicyclic train of other gears then is non-braking.Therefore, the epicyclic train free-runing operation of other each gears.Whether braking by controlling gear ring in each rank epicyclic train to be, and speed changer obtains different velocity ratios, thus the output different rotating speeds.Reach the purpose that changes velocity ratio.
The frictin braek that the gear ring of 1 grade of epicyclic train of this speed changer adopts, its braking plate adopts paper substrate or carbon back material, and adopts the multidisc structure, allow to exist in conjunction with the time skid.Thereby played the effect of clutch.Vehicle can be provided with clutch separately.
The invention has the beneficial effects as follows: energy is compatible manual control mode simultaneously, comes the speed change bending moment of controller motor vehicle.Simultaneously, under the situation of having exempted clutch, even do not need the intervention of fluid torque converter.Can also save the flywheel of motor.Transmission efficiency is suitable with conventional gears engagement speed changer.Structural rigidity is good, compact in architecture, and structural principle is simple, is convenient to maintenance analysis.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is an overall construction drawing of the present invention.
Fig. 2 be just-reversing selection mechanism structural drawing.
Fig. 3 is basic epicyclic train explanatory drawing.
Embodiment
In Fig. 1, transmission shaft (3) is an one with the planet carrier of each gear epicyclic train.Adorning planetary pinion (7) on the planet carrier of each gear epicyclic train.Planetary pinion (7) meshes with sun gear (10), gear ring (8) simultaneously.Gear ring (8) can be under the braking of break (9) and keep and the transmission case locking.Release brake (9) then gear ring (8) discord miscellaneous part is connected.The sun gear of each grade epicyclic train is meshed with carrier gear axle assembly (5).
In Fig. 2, the planet carrier (6) that is installed on the axle by free-sliding spline cover (2) can horizontally slip.About the respectively corresponding two kinds of motion conditions in two positions: when planet carrier (6) keeps left side then with gear ring (1) locking; Planet carrier (6) on the right side the time then with the transmission case locking.
In Fig. 3, the gear ring (3) that is sleeved on the axle can be under the braking of break (4), with the transmission case locking.
Claims (3)
1. a modularization meshes the brake type speed changer entirely, is just having-moveing backward the epicyclic train of selection mechanism and each velocity ratio to constitute, and it is characterized in that: by the braking of some parts in the epicyclic train being selected needed output velocity ratio.
2. speed changer according to claim 1 is characterized in that: just-reversing selection mechanism constitute by epicyclic train, planet carrier and gear ring or transmission case locking in the epicyclic train are all arranged, and reach the purpose of forward or reverse respectively.
3. pencil test according to claim 1 is characterized in that: the planet carrier in the epicyclic train of each velocity ratio, with the transmission shaft one or be rigidly connected; Each planetary pinion is tied to form arranged in arrays.
