Abstract
The invention relates to a tilting tray connecting rod-type continuously variable transmission, wherein a tilting tray is connected with two connecting rods, and rotates along with the rotation of a gear shaft; the connecting rods read the angle signals of the deflection angle of the tilting tray and the gear shaft; the rotation speed of the gear shaft is converted into the stroke distance of reciprocating movement back and forth of the connecting rods; two groups of gears are driven by racks which are integrated with the connecting rods into a whole; the gears are provided with single-way clutches; and the groups of gears are installed on a second gear shaft, and motive power is finally output through the second gear shaft. Different transmission ratios are obtained through regulating the deflection angle between the tilting tray and the gear groups, thus different rotation speed is output, and the aim for changing the transmission ratios is achieved.
Description
Technical field
The present invention relates to a kind of mechanical variable speed device, especially can be applicable to all kinds of motor vehicle and all kinds of motor driven equipments etc.
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.
At present, the known steel-belt type stepless speed variator circular cone dish that mainly is two pairs of synchronous diameter change of energy and a Steel Belt constitute.Regulate the diameter of this circular cone dish, just the variation velocity ratio of energy continuous stepless.Compact in architecture, the speed change continuous stepless, when especially combining with the computer automatic control technology, fuel-economizing the most.But such speed changer exists the steel band problem of slip.Can't transmitting large torque high-power, only be suitable for the little moment of torsion category of small-power.Especially under the situation of vehicle climbing, the load of speed changer is heavier.
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 swash plate link lever type stepless speed changer, 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.In addition, it can realize the speed changing effect of continuous stepless.
The technological scheme that its technical problem that solves the utility model adopts is: after the power engine power input, driving one just-reversing selection mechanism.Stir the plectrum in this mechanism, thus select in two gears in this mechanism one with the axle of this mechanism locking mutually.By control this just-plectrum of reversing selector, thereby the decision vehicle just changes or reverses.
Just-power of reversing selector output drives a gear shaft, and the other end of this gear shaft is installed the swash plate that can change the drift angle.Axle rotates then, and swash plate rotates.By control mechanism, can regulate the drift angle of this swash plate and gear shaft.
Swash plate links to each other with two connecting rods, and swash plate rotates along with the rotation of gear shaft, and connecting rod then reads the angle signal of swash plate and gear shaft drift angle.The stroking distance that the rotating speed of gear shaft is changed into the connecting rod front-rear reciprocation movement from.And and two groups of gears of rack drives of connecting rod one, overrunning clutch is installed on the gear.Gear train is installed on second gear shaft, and power is finally by the output of second gear shaft.Finally obtain different velocity ratios with the drift angle of gear train by regulating swash plate, thus the output different rotating speeds.Reach the purpose that changes velocity ratio.
The drift angle of this speed changer swash plate and gear train is 90 when spending, and the stroking distance of connecting rod is from being zero, the speed changer no-output.Thereby played the effect of clutch.Vehicle is not 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.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.The transmission range of speed changer is 0～the highest, and be the stepless continuous speed change.

Embodiment
In Fig. 1, power engine power is controlled input stage (3) input from clockwise and anticlockwise, after adjusting by velocity ratio controlled stage (2) then, output stage (1) output is arranged.
In the shown power output stage of Fig. 2, the to-and-fro motion of tooth bar (7), tooth bar (7) and overrunning clutch (4) engagement that gear has been installed, overrunning clutch (4) is installed on the output shaft (3).
Shown in Figure 3 turning in the orientation controlling and driving device, drive power from importing gear (1), drive axle (7) rotation.Be installed in the keep plate that can horizontally slip (5) rotation synchronously on the free-sliding spline cover (6).Keep plate (5) can horizontally slip, respectively with left and right sides braking plate (2) in a certain group of locking.Thereby drive loose gear (3) rotation that is enclosed within on the axle.
In velocity ratio controlled stage mechanism shown in Figure 4, main shaft (7) drives swash plate (1) rotation, and swash plate (1) is installed on the main shaft (7) by wobbler shaft (2), and the angle of swash plate (1) and main shaft (7) can change continuously.The position of push rod (3) and middle drive link (4) has then determined the angle of the relative main shaft of swash plate (1) (7).The slide block (8) that has tooth bar is then driven by whirlpool dish (6), and whirlpool dish (6) is then driven by worm screw (5).Make it have self-lock ability.
