Description
Technical field
The utility model relates to heavy goods vehicle, relates to a kind of planetary transmission hydraulic steering mechanism of realizing that wide-angle turns to.
Background technology
Modular dynamicliquid pressure flat bed transport vehicle is the novel equipment of big part transportation, has characteristics self-powered, module combinations, and along with the increase of composite module quantity, the load-carrying ability of whole car group can constantly increase.
Turning to manoevreability for big part transport trolley is the technological characteristics of a key, particularly modular dynamicliquid pressure flat bed transport vehicle can be realized craspedodrome, traversing and various steering mode, and it is big to require steering hardware to have moving corner, steering capability is strong, the characteristics that scantling of structure is little.Its steering angle of the mode of existing steering track rod and rack-and-gear is subjected to the restriction of mechanism structure and oad, the mode of worm and wormwheel then steering torque is subjected to the restriction of oad, and adopts the mode of HM Hydraulic Motor and planetary transmission can satisfy above-mentioned requirements well.
The utility model content
The purpose of this utility model is to propose that a kind of to have moving corner big, and steering capability is strong, and what scantling of structure was little can satisfy heavy transport trolley planetary transmission hydraulic steering mechanism.
The planetary transmission hydraulic steering mechanism that the utility model proposes, formed by vehicle frame 1, rotary encoder 2, HM Hydraulic Motor 3, pivoting support 4, wheel suspension 5, gear ring internal tooth 8, planetary wheel 9 and sun gear 10, wherein: the internally toothed annulus of pivoting support 4 is connected with vehicle frame 1, the outer ring is connected with the center shaft of wheel suspension 5 with planetary wheel 9, constitutes pinion carrier; Described pivoting support 4 internally toothed annuluss, pinion carrier and sun gear 10 constitute planet circular systems, and whole planet circular system is positioned at the space of pivoting support 4, and sun gear 10 is meshed with gear ring internal tooth 8 on the pivoting support by planet circular system; Adopt the hydraulic pressure matrix of low speed hydraulic motor 3 as power, the delivery orifice of hydraulic pressure matrix is connected with sun gear 10 by spline; Angle-position encoder 2 is built in the HM Hydraulic Motor 3.
In the utility model, a plurality of satellite gears 9 in the planet circular system arrange that evenly sun wheel 10 has floatability, make HM Hydraulic Motor 3 not bear radial weight, thereby do not need to arrange corresponding bearing combination.
The utility model adopts its corner of steering hardware of fluid motor-driven not to be subjected to the restriction of this body structure, can realize big corner arbitrarily, has improved the manoevreability that turns to of transport trolley widely.Owing to adopted planet circular system to increase moment of torsion, single HM Hydraulic Motor just can obtain bigger steering torque.Have certain floatability because a plurality of satellite gears, add the upper spline connection to the mutual balance of the diametral load of sun gear, HM Hydraulic Motor is not born radial weight, therefore the bearing combination need be set, as long as a hydraulic pressure matrix can produce operation torque.Planet circular system all is contained in the inner space of pivoting support, the entire mechanism compact conformation, and it is highly very low to take up room, and is particularly suitable for the modular dynamicliquid pressure flat bed transport vehicle of low loading surface height requirement.
Because the pivoting support of HM Hydraulic Motor and band internally toothed annulus is standardized product, the user need not to process the internally toothed annulus that needs special equipment voluntarily, and the utility model is easily manufactured, and structure is simple and direct.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A-A cutaway view.
Fig. 3 is the B-B cutaway view.
Number in the figure: 1-vehicle frame; The 2-rotary encoder; The 3-HM Hydraulic Motor; The 4-pivoting support; The 5-wheel suspension; 6-pivoting support and vehicle frame tie bolt; 7-pivoting support and suspension tie bolt; 8-gear ring internal tooth; The 9-planetary wheel; The 10-sun gear.
The specific embodiment
Further specify the utility model by reference to the accompanying drawings below by embodiment.
Consult shown in Figure 1ly, the utility model mainly comprises pivoting support 4, planetary wheel 9 and the sun gear 10 of rotary encoder 2, HM Hydraulic Motor 3, band internally toothed annulus.
The internally toothed annulus of pivoting support 4 is connected with vehicle frame 1, and the outer ring is connected, is equivalent to pinion carrier with the center shaft of wheel suspension 5 and planetary wheel 9, and sun gear 10 is connected with HM Hydraulic Motor 3, imports as motion.Internally toothed annulus, pinion carrier and sun gear 10 constitute a planet circular system, and the steering torque that HM Hydraulic Motor is produced amplifies, and makes the HM Hydraulic Motor 3 of single reduced size can drive wheel suspension.Whole planet circular system just in time is arranged in the interior volume of pivoting support 4.
The radial weight that adopts a plurality of even planetary wheels 9 that sun gear 10 is born is cancelled out each other, and the mouth of HM Hydraulic Motor 3 need not arrange that bearing makes up to bear radial weight, therefore only needs a hydraulic pressure matrix to produce drive torque.
The rear end of HM Hydraulic Motor 3 hydraulic pressure matrixs arranges rotary encoder 2, makes the steering angle of wheel suspension 5 obtain controlled reset, and the existence of planet circular system also makes the steering angle of feedback obtain amplifying, and has increased systemic resolution.
The hydraulic pressure matrix of HM Hydraulic Motor 3 and the height of rotary encoder 2 are very low, can be arranged in the inside of vehicle frame 1 carrier bar, satisfy low goods bogie frame designing requirement.
