Abstract
A special axle driven by oil motors mainly comprises brake drums (1), brakes (2), wheel covers (3), half shafts (4), an axle tube (5), claw clutches (6), planetary speed reducers (7), the oil motors (8), a flow valve (9) and a reversing valve (10), and is characterized in that the axle tube (5) is an integral straight shaft, two groups of the claw clutches (6), the planetary speed reducers (7) and the oil motors (8) are arranged inside the axle tube (5), each group only drives a wheel on one side; the speed of wheels is controlled by the flow valve (9); the wheels are controlled to advance or back by the reversing valve (10); and combination and separation of each oil motor (8) and the corresponding the planetary speed reducer (7) are controlled by the claw clutches (6). The axle has the advantages of simple structure, convenience for installation, reliable operation, high bearing capacity, fine synchronous effect of front driving and back driving, high climbing capability, high trafficability under muddy, soft, frozen and severe road environments, and applicability to all hinged tractors and certain mining cars.
Description
[technical field] the present invention is a kind of vehicle bridge, is a kind of special axle that drives with oil motor specifically.
[background technology] in May, 2005, I have invented a kind of radial type four-wheel drive tractor of hydraulic driven trailer trailing wheel, and, adapted to the demand of this trac. substantially at the clear two kinds of trailer special axles that drive with oil motor of in December, 2005 and 2009 7 phases of the moon secondary.But logical sale and use in a few years, many producers and user have higher requirement to the hydraulic pressure special axle, and the one, the installation capability of this special axle of requirement will be got well.Producer is for ease of producing, and the underframe that requires to adorn the underframe of hydraulic pressure special axle and adorn the common trailers axle can be general; The user, does not need former trailer underframe and stoste voltage rise bucket system are changed when requirement changes the outfit the hydraulic pressure special axle to former common trac. for ease of repacking.The 2nd, claimed structure is simple, and is easy to operate, cheap, durable in use.The 3rd, the many customer requirementies in the Northeast provide to them can the hydraulic pressure special axle of load-carrying more than 10 tons.
[summary of the invention] the invention provides a kind of special axle that adapts with it in order to satisfy vast producer and user to the higher requirement that the hydraulic pressure special axle proposes.
For solving its technical matters, the technical solution used in the present invention is: 1. change the vehicle bridge bridge tube into whole d-axis, increase the bearing capacity of vehicle bridge by the intensity that strengthens d-axis; 2. in bridge tube, be provided with two groups of oil motors, wheel of every group of oil motor independent drive; 3. in bridge tube, be provided with two groups of planetary reduction gears, be used to reduce the rotating speed of oil motor and increase output torque; 4. between two groups of oil motors and planetary reduction gear, be respectively equipped with denture clutch, when needing denture clutch closed, then denture clutch is not separated in the time of need be with the oil motor drive wheels with the oil motor drive wheels.5. save change speed gear box and conversion gear device, controlled the speed of rear wheel with the rotating speed of flow valve adjustment flow change oil motor.
The invention has the beneficial effects as follows: 1., improved the installation capability of special axle greatly owing to change the vehicle bridge axle housing into whole d-axis.The one, be convenient to manufacturer production, make the underframe of the underframe of dress hydraulic pressure special axle and dress common trailers axle can be general; The 2nd, make things convenient for the user to reequip, when former common trac. is changed the outfit the hydraulic pressure special axle, do not need former trailer underframe and stoste voltage rise bucket system are changed.2. owing to change the vehicle bridge axle housing into whole d-axis, can increase the bearing capacity of vehicle bridge by the intensity that strengthens d-axis, strengthened load-carrying capacity greatly; 3. since a wheel ， of every table oil motor independent drive Minus light the load-carrying capacity of oil motor, make oil motor be in work in the optimum condition for a long time, prolonged the service life of oil motor greatly; 4. owing to saved change speed gear box and conversion gear device, control the speed of rear wheel with the rotating speed of flow valve adjustment oil motor, not only simple to operate, and also the driving synchronous effect is better before and after making various trac.s; 5. owing to when not using back-wheel drive, handle denture clutch and make planetary reduction gear and oil motor be in complete released state, thereby reduced car resistance, strengthened sliding; 6. this vehicle bridge is simple in structure, and cost reduces more than 30% with respect to the vehicle bridge of similar load carrying ability.
[description of drawings] the invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present invention.
Among the figure: 1 braking hub, 2 drgs, 3 core wheels, 4 semiaxis, 5 bridge tubes, 6 denture clutchs, 7 planetary reduction gears, 8 oil motors, 9 flow valves, 10 change-over valves, 11 denture clutch bar handles.
[specific embodiment] is with reference to accompanying drawing: be provided with two groups of oil motors 8, denture clutch 6 and planetary reduction gear 75 li of bridge tubes; Denture clutch 6 is contained between oil motor 8 and the planetary reduction gear 7; Oil motor 8 drive wheels when denture clutch 6 is in binding site, oil motor 8 drive wheels not when denture clutch 6 is in disconnected position.The two ends of bridge tube 5 all are equipped with drg 2, core wheel 3, braking hub 1.One end of every semiaxis 4 is equipped with spline, and is meshed with the spline housing of planetary reduction gear 7 in the bridge tube 5; The other end of semiaxis 4 links to each other with core wheel 3 by bolt.Each braking hub 1 arrives core wheel 3 by bolt, in order to scroll forward and backward.Specific operation process is: a, the work of oil motor drive wheels.Handle denture clutch bar handle 11, make denture clutch 6 be in binding site, oil motor 8 drive wheels work.Thereby realize advancing of wheel and fall back by handling hand of rotation that the flow direction that change-over valve 10 changes high pressure oils changes oil motor 8.The not drive wheels work of b, oil motor.Handle denture clutch bar handle 11, make denture clutch 6 be in disengaged position, not drive wheels work of oil motor 8, wheel revolutions can instead not push away oil motor 8 rotations yet simultaneously.The speed of C, adjustment rear drive sprocket.Adjust that flow valve 9 changes the rotating speed of oil motors 8 and the speed of controlling rear wheel, make trac. before and after drive wheel keep best synchronous effect.
