Abstract
Disclosed is a driving device for a full hydraulic bulldozer, comprising two running main oil pumps, a diesel engine, a flywheel connected with the diesel engine, and a fan, a silencer and an air cleaner mounted on the diesel engine. The utility model is characterized in that a transfer case is arranged between the flywheel and the running main oil pumps which are respectively connected to the two sides of the transfer case. The transfer case consists of a transfer case housing, and a driving gear and driven gears arranged inside the housing. The transfer case housing is fixed with the flywheel, wherein the driving gear is disposed at the center and is connected with the flywheel; the driven gears mesh with the driving gear; the installation shafts of the driven gears are respectively connected with the output shafts of the two running main oil pumps. The flywheel is provided with a flexible connecting plate on which a shaft housing connected with the installation shaft of the driving gear is arranged. Provided with a transfer case which connects the running main oil pumps and the diesel engine, the utility model greatly shortens the suspension length of the of the oil pumps and avoids the leakage of the running main oil pumps, therefore the credibility of the utility model is increased, the credibility of the diesel engine and the service life of the diesel engine are increased.
Description
Technical field:
The utility model relates to the construction implement field, is specifically related to the improvement to the bulldozer power set.
Background technology:
Existing full hydraulic bulldozer dynamical system adopts diesel engine as power, and too high in order to prevent that full hydraulic bulldozer walking main oil pump discharge capacity from playing pressure regulation power, its rated speed is between 2100-2300, and rotating speed is higher than the diesel engine of mechanical type or hydraulic mechanical type bulldozer.Because hydraulic oil pump directly links to each other with diesel engine, therefore, full hydraulic bulldozer uses rotating speed generally between 2100-2300rpm with diesel engine.There is following defective in the full hydraulic bulldozer of having developed at present: (1) engine fuel consumption height, and noise is big; (2) the engine accessory power rating consumed power is big; (3) the diesel engine reliability is low; (4) be connected in series with the diesel engine flywheel owing to two walking oil pumps, thereby the suspension length of oil pump is longer, the vibration that is produced during walking can cause the loosening of fluid pressure line joint, the easy leakage of oil of walking oil pump, and its functional reliability reduces.
The utility model content:
Technical problem to be solved in the utility model is the defective that overcomes above-mentioned prior art, provide a kind of walking oil pump can leakage of oil, the full hydraulic bulldozer power set of functional reliability height.
Technical problem of the present utility model is to solve by following technical scheme.It comprises two walking main oil pump, diesel engine and the flywheels that join with it and is loaded on fan, noise damper and air filter on the diesel engine, it is characterized in that between flywheel and walking main oil pump transfer case being set, and is connected to the transfer case both sides.Described transfer case comprises transfer case housing and places interior driving gear of this housing and driven gear, transfer case housing and bell housing are affixed, the driving gear that joins with flywheel is equipped with in its center, two driven gears are meshed with driving gear, and its installation shaft is connected with two walking main oil pump power shafts respectively.The resilient connection plate is housed on flywheel, the axle sleeve that joins with the installation shaft of driving gear is housed on this gusset piece.
The utility model makes walking main oil pump and diesel engine and connect by transfer case is set, shorten oil pump greatly and hung length, the phenomenon of the easy leakage of oil of walking oil pump obtains eradicating, and its reliability is improved, and has improved the functional reliability and the application life of diesel engine simultaneously.

The specific embodiment:
The utility model is the improvement of being done on existing bulldozer power set.As shown in Figure 1, it comprises two walking main oil pump 9, diesel engine 3 and the flywheels 6 that join with it and is loaded on fan 1, noise damper 2 and air filter 4 etc. on the diesel engine 3, it is characterized in that between flywheel 6 and two walking main oil pumps 9, transfer case 8 being set, lay respectively at transfer case 8 both sides, promptly two main walking oil pumps 8 are connected on the transfer case 8, connect with flywheel 6 by transfer case 8 then, like this, can reduce the suspension moment of flexure of diesel engine bell housing 5, make the leakage of oil problem of walking main oil pump 9 obtain solution, improved the reliability of walking main oil pump 9 work.
The utility model transfer case 8 is an acceleration type, and the nominal operation rotating speed of the main oil pump 9 that can keep like this walking does not descend, and makes the discharge capacity of walking main oil pump 9 play the unlikely rising of pressure regulation power.It comprises transfer case housing 13 and places this housing interior driving gear 11 and driven gear 12, transfer case housing 13 is affixed with bell housing 5, driving gear 11 is equipped with in its center, join with flywheel 6, two driven gears 12 are divided into driving gear 11 peripheries and are meshed with it, its installation shaft is connected with two walking main oil pumps, 9 power shafts respectively, the power of flywheel 6 can be passed to two walking main oil pumps 9 by direct geared, finishes the output of power.
The utility model flywheel 6 adopts flexible connection mode with transfer case 8, the side that is connected with transfer case 8 at flywheel 6 is equipped with resilient connection plate 7, be fixed with axle sleeve 14 on this gusset piece, the splined hole of offering on it can match with the installation shaft upper spline of driving gear 11 to merge and drive driving gear 11 rotations.
The utility model diesel engine 3 can be reduced to 1800-1900rpm with the rated speed of work, and suitably increase the moment of torsion of maximum torque point under the constant situation of its rated power keeping.Along with the reduction of diesel engine 3 rated speeds, the noise of the combustion noise of diesel engine 3, mechanical noise, fan 1 etc. declines to a great extent, and simultaneously, the power that annexes such as fan 1, empty filter 4, noise damper 2 consume descends, and has therefore increased engine net power.Owing to the decline of diesel engine rated speed, improved the reliability and the application life of diesel engine work.
