Description
Technical field
The utility model relates to a kind of vehicle independent steering gear and a kind of rubber-tyred roller.
Background technology
Rubber-tyred roller is a desirable compacting equipment of building high-grade highway, airport, harbour, dykes and dams and industrial construction building site, the pavement behavior complexity of its operation, road surface, comparatively smooth expressway is not only arranged, some special road surfaces is also arranged, as about not contour road surface, tilted road surface, circular arc road surface etc.In order to satisfy many different construction operating modes simultaneously, should there be following specific (special) requirements in rubber-tyred roller steering mechanism:
Adapt to different road surfaces (as the smooth-riding surface, about not contour road surface, tilted road surface, circular arc road surface etc.), avoid overvoltage, virtual pressure; Turning radius and wheelbase are as far as possible little, make that equipment construction and transhipment are more convenient; Reduce the slippage when turning and trackslip the raising pavement quality; The dismounting of being convenient to tire changes the outfit etc.
Chinese patent CN200510032000 discloses a kind of steering actuator of rubber-tyred roller, this transfer realizes that by the oil cylinder that turns to that connects crotch and vehicle frame exterior bottom front-wheel integral body turns to, by rocking carrier realize tire about and fluctuate, the all tire of wheel assembly before so-called integral body turns to and is meant (3-6 is not waited) thus changeing the center realization that swings together by promotions wraparounds such as executive component such as oil cylinders turns to, therefore when turning to, need the bigger space that turns to, when simultaneously outside tire turns to and the relative displacement on road surface too big, thereby produce bigger slippage and trackslip.
This transfer has been saved cost to a certain extent, has improved the convenience of installation, maintenance and the ventilation effect of engine-cooling system.Yet, this transfer can only realize that front-wheel integral body turns to, the performance of aspects such as road pavement compliance, turning radius, solution slippage and the problem of trackslipping is still in urgent need to be improved, simultaneously, this transfer turns to and must occupy the bigger space that turns in order to carry out integral body, and this has caused suitable difficulty to its layout on rubber-tyred roller.
The utility model content
Therefore, the purpose of this utility model is to propose a kind of vehicle independent steering gear, and it can realize independent steering, the road pavement better adaptability, and turning radius is littler, has solved slippage well and the problem of trackslipping.In addition, the utility model also relates to a kind of rubber-tyred roller with independent steering gear of the above-mentioned type.
Above-mentioned purpose of the present utility model realizes that by a kind of vehicle independent steering gear it comprises: support is fixed on the vehicle frame of vehicle; Rocking carrier, hinged with support; Twoly go out rod oil cylinder, its cylinder barrel is fixed on the rocking carrier; And left and right two the independent steering unit that are connected to the two ends of rocking carrier, wherein, each independent steering unit includes: the bearing support that is connected with rocking carrier; And be rotatably installed in wheel shaft on the bearing support, wherein, two one of them piston rod and bearing supports that go out rod oil cylinder are hinged.By this according to independent steering gear of the present utility model, go out this oil cylinder and control two independently steering units simultaneously by means of two, two groups of four tires just can realizing vehicle one group of ground in twos turn to around the axis of bearing support, and this is with regard to the slippage of having been avoided tire as much as possible and the problem of trackslipping.Simultaneously, littler for the space requirement that this independent steering gear is installed on vehicle.
According to a preferred design scheme of the present utility model, bearing support comprises: vertical shaft, and its upper end is connected with rocking carrier; The fork pin can be sleeved on the vertical shaft rotatably with respect to the axis of vertical shaft.At this, wheel shaft can be rotated to support on the bottom of fork pin, and wherein, the fork pin is hinged with two one of them piston rod that goes out rod oil cylinder, and the bottom of fork pin is connected on the wheel shaft between two tires.
Hinged according to a preferred piston rod of the present utility model by being used to regulate the adjusting arm-tie of inside and outside steering angle difference and pitching pin.When vehicle turned to, the steering angle of the tire in the inboard and outside should be different, by use the adjusting arm-tie internally the outer steering angle degree mate, thereby the phenomenon of avoiding slippage better and trackslipping.
According to a design scheme of the present utility model, when rocking carrier by oscillating bearing or sliding bearing in the vertical direction can be around the rotation deflection ground of connecting axle when hinged, be very favorable with support.In the operating mode of reality, because the rugged situation in road surface might appear in the road conditions difference, and by above-mentioned design scheme, independent steering gear just can be swung according to the height on road surface is different, thereby adapts to road conditions better.
In further improvement project of the present utility model, propose, the bottom of fork pin can be hinged with wheel shaft around the rotation deflection of described bearing pin ground by the bearing pin in the vertical direction, and form between the bottom of fork pin and the wheel shaft to guarantee to make and pitch pin carries out deflection with respect to wheel shaft interval.So just can guarantee tire can be with the swing of wheel shaft independently about, fluctuate, and have and can limit the amplitude that tire floats.
In service in reality, tire might be crossed the hole.Therefore, the utility model proposes, each independent steering unit also comprises arm-tie, and this arm-tie is fixed on the vertical shaft from below support fork pin and arm-tie.Simultaneously, between upper end of pitching pin and rocking carrier, be provided with bearing shim and hold mill spare, and between bottom of pitching pin and arm-tie, also be provided with bearing and hold mill spare.Like this, under the effect of the traction of arm-tie, the wheel shaft that is connected on the fork pin just can not sink because of crossing the hole youngster.
Propose in a preferred design of the present utility model, vertical shaft is fixed on the rocking carrier by top cover-bolted mode or by the mode of welding respectively.
Preferably, a part is gone in vertical shaft milling on the external peripheral surface of vertical direction, with form between vertical shaft and the fork pin to be arranged on vertical shaft and described between oscillating bearing or the lubrication channel that is lubricated of sliding bearing, thereby lubrication oil or lubricating grease just can directly pass this passage the bearing that is arranged between vertical shaft and the fork pin is lubricated.
Further preferably, on fork pin or described wheel shaft, be fixed with cleaning shoe mechanism, so just can make cleaning shoe be close to tire, in time reliably the tire table is cleaned.
Should be appreciated that above generality is described and the following detailed description is all enumerated and illustrative, purpose is in order to provide further instruction to claimed the utility model.
