Description
Technical field
The utility model relates to a kind of construction machinery and equipment, is specifically related to a kind of slippage wheel type loader transmission device.
Background technology
Now general wheel type loader all adopts common cable to control and the work of acquisition of signal aspect electrical equipment control; Such mode has a lot of patching a little and a lot of cable winding points; Each point all is hiding a little of problem; Therefore the phenomenon that behind certain work-hours, just occurs aging, bad contact, contact failure easily occurs, from unfailing performance not with integrate with in the world.Traditional wheel type loader all adopts bridge architecture, that is: rear-axle drive, propons such as turn at characteristics, and the formula of bowing in particularly traditional loader turns to, and also is mid-turning to, and steering angle is excessive at work, is unfavorable for operation in the narrow space; Even can't operation in the middle of some special environment etc. technological drawback.Traditional minitype wheeled loader all adopts two two modes of changeing of driving to carry out operation; Under the impartial situation of power can't with the comparing of 4 wheel driven, and traditional wheel type loader is the bridge-type outputting power, in the bridge architecture diff arranged as you know; Such structure be advantage also be shortcoming; Its shortcoming is can't adapt to muddy and wet and slippery operating mode work, occurs the situation of skidding and can't advance easily, while also or skid motionless situation.The power of traditional wheel type loader just all reaches China's national standard on the type selecting of driving engine; But this gauged distance Europe three standards in the world also has certain distance; Can't satisfy of the requirement of world developed country, and aspect noise emission, do not controlled preferably for the environmental protection aspect.The lifting of wheel type loader all is to adopt the three-legged structure formula on market in the past; Loader(-mounted) shovel is the center with the back hinge-point of loading arm; From the lowest part to the highest point, draw arc; Such mode is the solstics of unloading distance in wherein certain of arc, this point also is to load the maximum point of the arm of force, therefore not only is not suitable for the narrow space operation and also makes some loss of takeoff output aspect.
Traditional loader is very complicated aspect controlling; Work on hand should be responsible for turning to, controlling multiway valve and carry out lifting and descend also controlling the conversion of gear and the conversion of front and back gear; The control of throttle and brake also will be carried out in the underfooting, makes under the complicated like this master mode that controlling personnel is easy to produce sense of fatigue.Developed country will also have certain distance for the comfort property that the bodily fuctions learns in the world together.
Summary of the invention
The utility model has overcome the deficiency of prior art, has proposed a kind of slippage wheel type loader transmission device, and said transmission device adopts the type of drive of 4 wheel driven, has increased the effect of motivation transfer motion part greatly, makes to adapt to more operating environment.Failure-free micro computer logic operation function has reduced rate of breakdown, thereby has reduced maintenance times, has also reduced the advantages such as time of the operation that dallies over one's work because of apparatus maintenance.
The technical scheme of the utility model is: slippage wheel type loader transmission device; Comprise a transmission case body, two HM Hydraulic Motors, a Left Drive mechanism and right transmission devices, said Left Drive mechanism is identical with right transmission device structure, symmetric offset spread; Be installed on the transmission case body; Said two HM Hydraulic Motors are installed in respectively on Left Drive mechanism and the right transmission device, on HM Hydraulic Motor, are provided with a Variable plunger pump, minor sprocket after hanging with a preceding minor sprocket and on the HM Hydraulic Motor; Preceding minor sprocket links together through preceding chain and preceding sprocket wheel, and back minor sprocket links together through rear chain and back sprocket wheel.
Before said, be provided with a wheel axle sleeve on the sprocket wheel.
On the sprocket wheel of said back, be provided with a wheel axle sleeve.
Said wheel axle sleeve is connected with a semiaxis through mechanical mechanism.
The utlity model has following beneficial effect:
The utility model adopts the type of drive of 4 wheel driven, has increased the effect of motivation transfer motion part greatly, makes to adapt to more operating environment.Failure-free micro computer logic operation function has reduced rate of breakdown, thereby has reduced maintenance times, has also reduced the advantages such as time of the operation that dallies over one's work because of apparatus maintenance.
Description of drawings
Further specify the utility model below in conjunction with the accompanying drawing and the specific embodiment.
Fig. 1 is the utility model hanger structure scheme drawing.
Among the figure, 1. back sprocket wheel; 2. wheel axle sleeve; 3. semiaxis; 4. preceding sprocket wheel; 5. preceding chain; 6. minor sprocket after; 7. HM Hydraulic Motor; 8. transmission case body; 9. rear chain; 10. preceding minor sprocket.
The specific embodiment:
Referring to shown in Figure 1, the utility model comprises Left Drive mechanism and right transmission device, and Left Drive mechanism is identical with right transmission device structure; Symmetric offset spread; Be installed on the transmission case body 8, each transmission device is provided with a HM Hydraulic Motor 7, therefore; The utility model one has two HM Hydraulic Motors 7 and drives; Minor sprocket 6 after hanging with a preceding minor sprocket 10 and one on each HM Hydraulic Motor 7, preceding minor sprocket 10 be through the action edge transmission of going forward side by side that links together of preceding chain 5 and preceding sprocket wheel 4, and back minor sprocket 6 is through the action edge transmission of going forward side by side that links together of rear chain 9 and back sprocket wheel 1.Before said, be provided with a wheel axle sleeve 2 on the sprocket wheel 4.On the sprocket wheel 1 of said back, also be provided with a wheel axle sleeve 2.Said wheel axle sleeve 2 is connected with a semiaxis 3 through mechanical mechanism.Such pattern has just formed four wheel drive.Each HM Hydraulic Motor 7 all is to be controlled by a Variable plunger pump, and such structure design can embody a side or bilateral carries out takeoff output simultaneously, has avoided because the situation that muddy operation operating mode makes car load skid occurs.HM Hydraulic Motor 7 of each Variable plunger pump control; That is to say that two wheels that Left Drive mechanism or right transmission device are controlled can operate separately, the left side can travel forward, and can move simultaneously backward in the right side; Under such mode of motion, just can realize the pivot stud of car load; And steering angle can carry out conversion arbitrarily, has so just changed the restriction of the turn radius on the traditional mode, thereby has improved operating efficiency.
