Description
1, technical field
The utility model relates to a kind of mechanical transmission accessory, specifically a kind of hydraulic stepless speed variator.
2, technical background
The speed change gear kind of using in the mechanical transmission is a lot, for example on some production line, need in the machinery of speed change work, also adopted the mechanical stepless speed changes transmission in the variable ratio drive system of motor vehicle.The particularly application of mechanical stepless speed-changing gearing on automobile, thus realize motor and the best power performance of automobile and the coupling of Best Economy, reduced the pollution of environment.Stepless change is optimal transmission device.That the mechanical stepless speed changes transmission has is simple in structure, handle with keep in repair ten thousand just, low noise advantages; Therefore, can adapt to variable working condition, simplify transmission system, energy-conservation and reduce requirement such as environmental pollution.Along with the raising of industrial expansion and flow mechanization, automaticity, mechanical stepless speed-changing gearing is used increasingly extensive at home and abroad as the important mechanical transmission component of a class.
But mostly employed mechanical stepless speed-changing gearing is to come transferring power, in use existing deficiency to be by friction in the prior art, and transmission efficiency is lower, and working life is short, and impact resistance is poor, and the power that can transmit is limited.
3, summary of the invention
The utility model is at the deficiency of existing mechanical stepless speed changes devices and shortcoming, provides that a kind of slewing range is big, transmission efficiency is high, transmission power is big, in light weight, simple in structure, hydraulic control mechanical stepless transmission that volume is little.
The purpose of this utility model realizes in the following manner, adopt planetary type gear transmission unit being in transmission connection a little as power, adopt the driving torque of hydraulic damper control planetary type gear transmission unit, realizable force is from the controlled variable transmission of a transmission shaft to another transmission shaft.In actual applications, two sun gears join with power input shaft and pto respectively, one cover planetary pinion meshes two sun gears simultaneously, the hydraulic damper planetary carrier links to each other, and hydraulic damper is controlled rotating ratio between pto and the power input shaft by the rotating speed of control planet carrier.The working principle of hydraulic damper is by mechanical transmission the moment of rotation of planet carrier just to be become the to-and-fro motion of piston in hydraulic jack, realize damping by the flow of valve control hydraulic oil turnover oil cylinder to planet carrier, when valve wide open, the working medium of turnover oil cylinder does not have resistance, planet carrier drives reciprocating motion of the pistons at full speed, this moment, the rotating speed velocity ratio of power input shaft and pto was 1: 0, when controlling the flow of the medium that passes in and out oil cylinder by valve, planet carrier drives reciprocating motion of the pistons will produce resistance, along with the variation power input shaft of resistance and the rotating ratio between the pto will change from 0-1, it is 1: 1 up to rotating ratio.Thereby its gear ratio can be by 0 to 1 stepless change.
When flow control valve cut out fully, oil hydraulic pump was motionless with the planetary carrier locking.At this moment rotating ratio is 1: 1 pure gear transmission, owing to hydraulic damper is not worked, thereby has reduced the wearing and tearing of hydraulic damper, has prolonged the working life of whole device.
Accompanying drawing is the structural representation of hydraulic stepless speed variator.
4, description of drawings
Explain below with reference to Figure of description hydraulic stepless speed variator of the present utility model being done.
Hydraulic stepless speed variator of the present utility model, its structure be by Left Drive axle 1, right power transmission shaft 12, OK Star transmission device, hydraulic damper consist of, and planetary driving device is by pinion frame 5, planetary gear 3 And left and right sides central gear 4 forms, and planetary gear 3 is arranged on the limit section of pinion frame 5 by axle 2, and two too Sun gear 4,15 is arranged between the planetary gear 3 intermeshing, and Left Drive axle 1 passes pinion frame 5 left sides Side and left central gear 15 join, and right power transmission shaft 12 passes pinion frame 5 right sides and right central gear 4 phases Connect, hydraulic damper and pinion frame 5 join.
Hydraulic damper is made up of swash plate 6, piston shoes dish 7, ball head connecting rod 8, piston 9 and cylinder body 11, Swash plate 6 is fixed together with pinion frame 5, and the inclined-plane of swash plate 6 and piston shoes dish 7 join, and piston shoes dish 7 is logical Cross ball head connecting rod 8 and join with piston 9, piston 9 is arranged in the oil cylinder 10 on the cylinder body 11, oil cylinder 10 with Link to each other by pipeline 13 between the oil cylinder 10, be provided with choke valve 14 on the pipeline 13, the both sides of planet carrier, oblique The centre of dish 6, piston shoes dish 7 and cylinder body 11 arranges porose, and right power transmission shaft 12 passes cylinder body 11, piston shoes Interstitial hole and the right central gear 4 of dish 7 and swash plate 6 and pinion frame 5 sides join.
5, mode of execution
Its processing and fabricating of hydraulic stepless speed variator of the present utility model is very simple and convenient, designs and produces shown in the by specification accompanying drawing to get final product.Hydraulic damper can be arranged on the left side or the right side of planetary carrier, and the effect of its generation is identical.Damping control to planetary carrier, except the mode that adopts swash plate as the transfer, also can again its oil circuit be controlled and then planetary carrier is produced damping and control the speed Control that realizes two transmission shafts by the work of gear driven crankshaft-link rod driven plunger.
Use of the present utility model is very simple and convenient, sun gear and input shaft in the planetary carrier join, another sun gear and output shaft join, planetary pinion meshes two sun gears simultaneously, planetary carrier be connected with the hydraulic damper flow of inflow-rate of water turbine control valve control hydraulic jack and the driving torque of pressure and then control planetary carrier.
Hydraulic stepless speed variator of the present utility model is compared with existing technology, have reasonable in design, structure is simple Single, be easy to the characteristics such as processing, volume is little, easy to use, of many uses, thereby, have well Popularizing value.
Except the described technical characterictic of specification, be the known technology of those skilled in the art.
