Description
Technical field:
The utility model relates to a kind of engineering machinery, and feature relates to a kind of hydrostatic drive land leveller.
Background technology:
In the prior art, land leveller walking power transmission route is: motor → fluid torque-converter (or clutch) → gearbox → power transmission shaft → drive axle → tandem-driving bogie → wheel, control the travel direction (advance or fall back) and the speed of a motor vehicle conversion of land leveller with the gear that changes gearbox, the differential of two side drive wheels and synchronous when keeping straight on when realizing the land leveller turning driving with the symmetrical transmission mechanism that is installed in differential mechanism in the drive axle and main transmission both sides.This sharp power transmission, speed change gear are because its drive path is long, machinery zero, the parts of participating in transmission are many, thereby causing that complex structure, transmission performance are poor, maintenance difficult, manufacturing cost height, quality instability, be easy to generate fault, is to cause one of low principal element of land leveller coefficient of reliability.
Summary of the invention:
Technical problem to be solved in the utility model provides that a kind of drive path is short, simple in structure, technical performance is advanced, easy to maintenance, reliable in quality, production and the low hydrostatic drive land leveller of use cost.
The technical solution adopted in the utility model is: the volume adjustable hydraulic pump in the hydrostatic transmissions system is in transmission connection by shaft coupling and motor, the power shaft of the output shaft of the variable hydraulic motor that is communicated with volume adjustable hydraulic pump and deceleration tandem-driving bogie is in transmission connection, and the output shaft and the wheel of deceleration tandem-driving bogie are in transmission connection.
The utility model is owing to adopted technique scheme, engine power is transferred to wheel, the driving land leveller travels, and realizes control to land leveller travel direction (advance or fall back) and speed of a motor vehicle conversion with the size at the swash plate angle of inclination of swash plate incline direction that changes volume adjustable hydraulic pump and variable hydraulic motor respectively; Hydraulic pump and hydraulic motor be hydraulic transmission element be again shifted (commutation) device, substituted fluid power one machine driving and shifted (commutation) function of fluid torque-converter of the prior art and gearbox; The deceleration tandem-driving bogie is the tandem-driving bogie of land leveller, it is again reducer, tandem-driving bogie of the prior art and gearbox have been substituted, the balance and the deceleration of drive axle-tandem-driving bogie assembly, thereby cut complex structure of the prior art, the manufacturing cost height, the torque-converters that costs an arm and a leg and very easily break down (or clutch), gearbox, power transmission shaft, drive disk assemblies such as drive axle, transmission efficiency is up to 75～80%, the speed of a motor vehicle that falls back is fast, can reach 35km/h, improved job execution efficient, so the utlity model has simple in structure, transmission gear shift is reliable, easy to maintenance, low cost of manufacture, steady quality, advantages such as result of use is good.
Description of drawings:
Fig. 1 is a power transmission arrangment schematic diagram of the present utility model.
The specific embodiment:
Referring to Fig. 1, variable piston hydraulic pump 2 in the hydrostatic transmissions system is in transmission connection by shaft coupling 11 and motor 1, the output shaft of the variable piston hydraulic motor 3,6 that is communicated with variable piston hydraulic pump 2 is in transmission connection with the power shaft of fixed shaft type gear reduction tandem-driving bogie 4,7 respectively, and the output shaft of fixed shaft type gear reduction tandem-driving bogie 4,7 is in transmission connection with wheel 5,8,9,10 respectively.
The drive path of the utility model traveling power transmission is: motor 1 → shaft coupling 11 → variable piston hydraulic pump 2 → variable piston hydraulic motor 3,6 → fixed shaft type gear reduction tandem- driving bogie 4,7 → wheel 5,8,9,10, promptly drive 2 work of variable piston hydraulic pump by shaft coupling 11 by motor 1, variable piston hydraulic pump 2 drives variable piston hydraulic motor 3,6 work, variable piston hydraulic motor 3,6 drive fixed shaft type gear reduction tandem-driving bogie 4 respectively, 7 work, fixed shaft type gear reduction tandem-driving bogie 4,7 drive wheel 5 respectively, 8,9,10 rotate, thereby finished land leveller from motor 1 to wheel 5,8,9,10 power transmission, the driving land leveller travels, respectively with the swash plate incline direction and the variable piston hydraulic motor 3 that change variable piston hydraulic pump 2, the size at 6 swash plate angle of inclination realizes the control to land leveller travel direction (advance or fall back) and speed of a motor vehicle conversion.Variable piston hydraulic pump 2 and variable piston hydraulic motor 3,6 be hydraulic transmission element be again shifted (commutation) device, substituted fluid power-machine driving and shifted (commutation) function of fluid torque-converter of the prior art and gearbox; Fixed shaft type gear reduction tandem-driving bogie 4,7 is the tandem-driving bogie of land leveller, it is again reducer, the balance and the deceleration of tandem-driving bogie of the prior art and gearbox, drive axle-tandem-driving bogie assembly have been substituted, thereby drive disk assemblies such as complex structure of the prior art, manufacturing cost height, the torque-converters (or clutch) that costs an arm and a leg and very easily break down, gearbox, power transmission shaft, drive axle have been cut, transmission efficiency is up to 75～80%, the speed of a motor vehicle that falls back is fast, can reach 35km/h, improve job execution efficient.The utility model adopts hydrostatic, no gearbox, drive axle-free, no drive axle transmission, and land leveller can be realized full wheel drive and stepless fluid drive manipulation at an easy rate, thereby can improve the tractive force of land leveller greatly and use operating characteristics.By the processing of computer by the real-time rotary speed data of driving wheel that the speed measuring device ratio that is installed on the land leveller both sides fixed shaft type gear reduction tandem-driving bogie 4,7 is recorded, automatically control drives the rotation of wheel, thereby has solved the slippage and the problem of trackslipping of two side drive wheels under the different travel conditions of land leveller (as: keep straight on, the turn) situation different with ground attaching coefficient in the existing land leveller technology effectively.
