Technical field
The utility model is a kind of mechanical transport, is meant that especially a kind of rubber belt track that is used for marshy area, marshy area, seabeach and snowfield makes the machinery of the transportation and the operation of ground-engaging element, full hydraulic drive.
Background technology
Transport Machinery is since inventing, and just production, the life with people is closely connected together, and it has played a kind of important effect in people's production and life.Having under the situation of road, general wheeled car is best transportation means, but under the abominable road conditions or way less situation such as marshy area, marshy area, seabeach and snowfield, general wheel car just seems powerless.China is vast in territory, and geographical environment and climatic conditions have nothing in common with each other, and adds that economy is flourishing inadequately, and the agricultural machinery popularity is lower, and the production in the vast rural area, living material are still chosen by people's push arm under most situation, and labour intensity is big, inefficiency.Along with development and national economy, the raising of living standards of the people, particularly rural area need the goods and materials of transportation more and more.The rise of earlier year agriculture truck for the transportation of alleviating material used for agriculture plays a good role, makes agriculture truck form a very big industry.Recently, the Central Committee of the Communist Party of China is in about the suggestion of formulating Eleventh Five-Year Plan, building a New Socialist Countryside as an important historic task in China's modernization, and the construction that advances modern agriculture construction, reinforcement agricultural facility, as one of important measures of realizing this goal, wherein strengthening farmland construction, improve level of farming mechanization, is again the most important thing.Along with the paces of rural area capital construction are accelerated, need be more and more in the situation of operation under the special environment, the goods and materials that requirement is transported under extraordinary condition are also poly-to be increased, general wheeled car is because of being subjected to the restriction of its usage condition, can't satisfy the demand of operation in particular cases, the peasant is anxious expect have a kind of can grading operation, again can be at marshy area, even can under the abominable road conditions such as marshy area, seabeach, snowfield or do not having under the situation of road yet can operation Transport Machinery.Chinese patent CN92216111.9, name is called " rubber belt track all-terrain vehicle " and discloses a kind of rubber belt track all-terrain vehicle, but it is a kind of walking machine of mechanical type drive mechanism, the walking machine of mechanical type drive mechanism is not only operated and is not very convenient, especially turn to dumb, and structure is very complicated, so be subjected to certain influence in application.Therefore, necessary this is improved.
The utility model content
The utility model is the demand at present vast rural area, and research and development a kind of can be in operation on level land, hag, marshy area and the Ordinary road, the caterpillar conveyer full hydraulic drive transport trolley of the on-mechanical drive mechanism of the operation that can do as usual under mal-conditions such as marsh, way, beach, shallow sea, desert, snowfield again.
The technical scheme pointed according to the purpose of this utility model is: adopt hydraulic driving mode to drive crawler type walking mechanism, utilize HST static pressure technology, driving engine is to overlap the left and right sides creeper undercarriage of the fluid pressure drive device difference powered vehicle that splits, the walking of realization vehicle by two.What wherein, described fluid pressure drive device adopted is the high-pressure plunger controllable capacity pump; Comprise wheel reduction gear in the described creeper undercarriage, wheel reduction gear is a variable-speed bearing.Fluid pressure drive device according to said method comprises driving engine, transmission gearbox, drive wheel and rubber belt track, and driving engine links to each other with transmission gearbox, its characteristics are to be provided with the fluid pressure drive device that two covers split between transmission gearbox and drive wheel, the drive wheel of left and right sides creeper undercarriage is to drive by the fluid pressure drive device that splits, every cover fluid pressure drive device comprises high-pressure plunger controllable capacity pump and HM Hydraulic Motor, the high-pressure plunger controllable capacity pump is connected with HM Hydraulic Motor with transmission gearbox respectively, wherein, the high-pressure plunger controllable capacity pump is that mechanical type is connected with transmission gearbox, and high-pressure plunger controllable capacity pump and HM Hydraulic Motor are that to adopt hydraulic way bonded assembly, HM Hydraulic Motor by oil pipe be hydraulic oil driven rotary by the output of high-pressure plunger controllable capacity pump.HM Hydraulic Motor is connected by the drive wheel of wheel reduction gear with left and right sides creeper undercarriage again, and is driven the rubber belt track walking of creeper undercarriage by drive wheel.
Concrete mode of operation is: the power of driving engine adopts HST static pressure device, drive two high-pressure plunger controllable capacity pump rotations through transmission gearbox, pressure oil arrives left and right HM Hydraulic Motor through oil pipe, make HM Hydraulic Motor produce rotation, and through the rotation of wheel reduction gear drive drive wheel, drive the rubber belt track moving linearly by drive wheel again, produce motion thereby order about machine.By to the adjusting mechanism on the motor, change or cut off the flow of the pressure oil that flows to HM Hydraulic Motor, can change the rotating speed of motor or stop operating, thereby can change the kinematic velocity of machine; By adjustment to the motor eccentric throw, (by manually, surge or electronic) velocity of rotation of left and right motor is differed or the rotation direction difference, thereby reach the purpose of the sense of motion that changes machine; And machine original place 360 degree are rotated, to adapt to operation on narrow place.
The utility model adopts the ripe construction machinery and equipment manufacturing technology of hydraulic components, the utilization of domestic production, develops, adopts rubber belt track to make a kind of short-haul vehicle of ground-engaging element in conjunction with current China vast rural area environment for use and economic situation, it can satisfy the needs of operation under the complex environment, has the advantage that general wheeled car does not have; Modification a little can also be drawn under abominable road conditions as industries such as oil industry, forestry, salt industry, aquaculture, exploration industry, water conservancy, flood control and forest fire prevention and controls, transportation and operation.
Characteristics of the present utility model are: utilize the HST static pressure device of current up-to-date development, the manufacturing technology in conjunction with ripe construction machinery and equipment be used for field machine, thereby no matter the field machine that makes China has all promoted a class from being designed into manufacturing; Owing to adopt the static pressure transmission, can cancel cumbersome, heavy mechanical drive, thereby alleviate the deadweight of machine, it is more reasonable to arrange; Its crossing ability and cross-country traveling ability all are greatly improved; Because of having adopted hydraulic control technology, it handles very light and flexible, thereby has reduced labor intensity of operating personnel; Because adopt rubber belt track to make ground-engaging element, vibration is little during walking, noise is low, has not only improved the traveling comfort of driving, and improved the anti-ability of sinking of machine greatly; Travel to adapt under abominable road conditions such as marsh, marshy area; In order to prevent accident, also increased and used hydraulically powered self-help apparatus; Operator's compartment can be made open type (operating console) or enclosed, and can be according to user's requirement, and the configuration air-conditioning is to increase the traveling comfort of driving.
