According to the double-steel-wheel road roller, the structure of the articulated steering device is improved, so steering of the double-steel-wheel road roller is more stable, the stress of the swing bearing is reduced, the service life of the swing bearing is prolonged, and the use cost is reduced.
Description
Technical field
The utility model relates to a kind of articulated steering device of dual-steel wheel road roller, belongs to technical field of engineering machinery.
Background technology
The steering mode of at present two steel wheel series rollers is all articulation steering, has under normal circumstances following two kinds of connection modes:
1), steering cylinder connects forward and backward hinged seat, rear hinged seat is fixedly connected with (as Fig. 4) by swing bearing with rear vehicle frame;
2), steering cylinder connects body cradle and rear hinged seat, rear hinged seat is to be also fixedly connected with (as Fig. 5) by swing bearing with rear vehicle frame;
But the machine connecting in these two kinds of modes is in the time turning to work, conventionally can produce two kinds of adverse influences: 1, due to steering cylinder turn to the arm of force (between the line of centers of hinged seat and steering cylinder junction and rear hinged seat and the line of centers of body cradle junction distance) less, steering stability can be poor accordingly; 2, because rear hinged seat is to be fixedly connected with by swing bearing with rear vehicle frame, after in the time that rear hinged seat rotates, vehicle frame also and then rotates together, between them, carry out power transmission by swing bearing, this just makes swing bearing be in for a long time this turning under effect of stress, can allow like this swing bearing reduce greatly service life, improve the use cost of machine.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of stable direction is provided, and ensures the swing bearing life-span, and the articulated steering device of the dual-steel wheel road roller reducing costs.
The purpose of this utility model is achieved in that
The articulated steering device of the utility model dual-steel wheel road roller, it is fixed on two turning center axles on body cradle by four cover plates and four oscillating bearings, constituent elements one, swing bearing is fixed on rear hinged seat, constituent elements two, parts two are fixed on the turning center axle in parts one with top board and lower platen, form total parts, then with pressing plate, the turning center axle of one end of described total parts is fixed in front vehicle frame, the swing bearing of the other end of described total parts is fixed on rear vehicle frame with bolt, then with two connecting pins, crab row oil cylinder one end is arranged in front vehicle frame again, the other end is arranged on body cradle, two steering cylinder one end are arranged on rear vehicle frame with four connecting pins, the other end is arranged on body cradle.
On described rear vehicle frame, be fixed with block with bolt.
The articulated steering device of the utility model dual-steel wheel road roller has the following advantages:
The articulated steering device of this dual-steel wheel road roller improves by the structure to articulated steering device, can make turning to of dual-steel wheel road roller more stable, alleviate the stressed of swing bearing simultaneously, extend the service life of swing bearing, reduced use cost simultaneously.
Brief description of the drawings
Fig. 1 is the structural representation of the articulated steering device of the utility model dual-steel wheel road roller.
Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the enlarged drawing at swing bearing and rear vehicle frame place in Fig. 1.
Fig. 4 is the first connection mode of articulated steering device in the past.
Fig. 5 is the second connection mode of articulated steering device in the past.
In figure: front vehicle frame 1, body cradle 2, turning center axle 3, oscillating bearing 4, rear vehicle frame 5, swing bearing 6, rear hinged seat 7, lower platen 8, top board 9, pressing plate 10, cover plate 11, crab row oil cylinder 12, steering cylinder 13, block 14, connecting pin 15, set pin 16.
Detailed description of the invention
Referring to Fig. 1 to Fig. 3, the utility model relates to a kind of articulated steering device of dual-steel wheel road roller, by four cover plates 11 and four oscillating bearings 4, two turning center axles 3 are fixed on body cradle 2, constituent elements one, swing bearing 6 is fixed on rear hinged seat 7, constituent elements two, parts two are fixed on the turning center axle 3 in parts one with top board 9 and lower platen 8, form total parts, then with pressing plate 10, the turning center axle 3 of one end of described total parts is fixed in front vehicle frame 1, the swing bearing of the other end of described total parts 6 is fixed on rear vehicle frame 5 with bolt, then with two connecting pins 15, crab row oil cylinder 12 one end are arranged in front vehicle frame 1 again, the other end is arranged on body cradle 2, two steering cylinder 13 one end are arranged on rear vehicle frame 5 with four connecting pins 15, the other end is arranged on body cradle 2, thereby form whole articulated steering device.
When after steering cylinder 13 work make, vehicle frame 5 turns an angle around the relative body cradle 2 of turning center axle 3, top board 9 immediate roofs are to the positioning plate in body cradle 2, now rise and turn to position-limiting action, this rotational angle size is by the positioning plate determining positions of top board 9 structures and body cradle 2.
When the base plate of body cradle 2 and the hole of lower platen 8 are to timing, set pin 16 is inserted, now can not turn to, required when this state is machine transport, in order to protect steering cylinder not stress.
Implementation process of the present utility model is as follows:
One, in the time that machinery requirement carries out handling maneuver, driver makes pressure oil enter two steering cylinders 13 by operation deflector, steering cylinder 13 will be in flexible mode of operation, and now rear vehicle frame 5 just rotates around turning center axle 3, thereby realizes the turning function of machine.Together with the corresponding swing bearing 6 being fixedly connected with rear vehicle frame 5, rotate, due to steering cylinder 13, just direct effect power is in rear vehicle frame 5, and now swing bearing 6 has just been exempted from the power transmission of picture conventional steering articulated mounting to rear vehicle frame 5, thereby has extended its service life.
Two, in the time that machinery requirement carries out crab row, driver makes pressure oil carry out crab row oil cylinder 12 by operation electromagnetic valve, crab row oil cylinder 12 will be in flexible mode of operation, now front vehicle frame 1 is just rotated around turning center axle 3, simultaneously driver operates deflector again rear vehicle frame 5 is rotated around turning center axle 3 with it, and when rear vehicle frame 5 turns to and the shut-down operation when parallel of front vehicle frame 1 end face, at this moment their end faces are not just on same straight line, but generation offset distance, thereby realize the crab row function of machine.
Three, in the time that machinery requirement transports, driver can operate deflector makes two steering cylinders be in expanding-contracting action, when the base plate of body cradle 2 and the hole of lower platen 8 are to timing, set pin 16 is inserted fixing, thereby avoided the destruction of fluctuating to steering cylinder 13 because of rear vehicle frame 5 in the time of transport.
The example of the above is only preferred embodiments of the present utility model, and not this limits practical range of the present utility model, therefore all methods according to invention and equivalence variation that principle is done evenly should be covered by protection domain of the present utility model.
