Abstract
The turning executor for wheel type road roller includes rock bit, rotary bearing, fork and turning oil cylinder. The rotary bearing has outer ring is connected to the chassis of the road roller and inner ring connected to the fork, the fork is connected to the rock bit, and the turning oil cylinder has one end fixed to the outside bottom of chassis and the other end connected to the fork. The present invention can meet the turning requirement of road roller, has radically improved engine ventilating and cooling condition, low cost, maintenance convenience and high overall work efficiency.
Description
Technical field
The present invention is mainly concerned with the field of road engineering machinery field, refers in particular to a kind of steering actuator of rubber-tyred roller.
Background technology
In the prior art, for the go the big figure rubber-tyred roller of front-wheel of integral body, the design of its oil cylinder all the time all is that two oil cylinder effects are arranged.Referring to Fig. 1 and Fig. 2, under the certain situation of wheelspan, rocking carrier 1 is fixed tire together, and crotch 4 is with rocking carrier 1 and turn to oil cylinder 5 to link to each other.Owing to turn to oil cylinder 5 in vehicle frame 6, vertically to arrange along vehicle frame 6, turn to being fixedly hinged a little under the motor wind scooper of oil cylinder 5, this not only makes installation, the dismounting inconvenience that turns to oil cylinder 5, also causes the motor wind scooper to draw badly, and the engine radiator radiating efficiency is descended.In addition,, occupied the space of vehicle frame 6, made motor wind scooper and radiator dismounting difficulty when maintenance owing to turn to oil cylinder 5 vertically to be arranged in vehicle frame 6 inside.And double steering oil cylinder 5 turn-around design are in order to avoid the interference of rocking carrier 1, to have to stressed relatively when layout turns to the moveable hinge contact of oil cylinder 5 and the motion state asymmetric arrangement.Two turn to the movement travel of oil cylinder 5 and stress extremely inconsistent when turning to, when one of them turns to the active force arm of force of oil cylinder 5 to reach maximum, another active force arm of force that turns to oil cylinder 5 is minimum and approaches 0, this just greatly reduces the operating efficiency that turns to oil cylinder 5, has increased the manufacturing cost of hydraulic system.
Summary of the invention
The technical problem to be solved in the present invention just is: at the bad and ineffective problem of result of ventilating heat dissipation that causes inconvenient maintenance, motor in the prior art owing to the two oil cylinder turn-around design of employing, the invention provides a kind of requirement that turns to that can either satisfy rubber-tyred roller, can fundamentally improve the ventilation cooling effect of motor again, and the steering actuator of rubber-tyred roller with low cost, easy to maintenance, that whole work efficiency is high.
In order to solve the problems of the technologies described above, the solution that the present invention proposes is: a kind of steering actuator of rubber-tyred roller, it comprises rocking carrier, pivoting support, crotch and turns to oil cylinder, it is characterized in that: the outer ring of described pivoting support links to each other with vehicle frame, the inner ring of pivoting support is connected with crotch, and described crotch links to each other with rocking carrier; One turns to oil cylinder one end to be fixed in the vehicle frame exterior bottom, and the other end links to each other with crotch.
Described crotch links to each other by bearing pin with rocking carrier.
Compared with prior art, the invention has the advantages that: the steering actuator of rubber-tyred roller of the present invention only adopts an oblique bottom of frame that is arranged in of oil cylinder, the moving pin joint of oil cylinder arranges that based on the oil cylinder stroke near symmetrical cylinder force distributes near best distribution to the arm of force of the front-wheel centre of gyration; Oil cylinder is fixedly hinged and a little is arranged in the vehicle frame outside, and this has just avoided the motor wind scooper up hill and dale, has vacateed the space after oil cylinder being fixedly hinged a little shift out, and just makes the Change In Design of wind scooper have possible; Along with the design that can revise wind scooper and vehicle frame, oil cylinder has been vacateed the space after being fixedly hinged and a little shifting out just makes the Change In Design of wind scooper that possibility has been arranged.Not only improve the performance of breathing of engine cooling, also improved the maintainability that turns to oil cylinder and engine radiator, reduced cost of production.In addition, turn to oil cylinder quantity only to be one, therefore not only can reduce production costs, the dismounting during maintenance of maintenace points such as oil cylinder, radiator, the inconvenient problem of installation also have great convenience for the user, and help promoting the sale of product.

The specific embodiment
Below with reference to accompanying drawing the present invention is described in further details.
As Fig. 3, Fig. 4 and shown in Figure 5, the steering actuator of a kind of rubber-tyred roller of the present invention, it comprises rocking carrier 1, pivoting support 2, crotch 4 and turns to oil cylinder 5.Rocking carrier 1 is fixed tire together; The outer ring 22 of pivoting support 2 is screwed on vehicle frame 6, and 21 of the inner rings of pivoting support 2 are connected with crotch 4 with screw, is provided with a circle rolling steel balls between the inner ring 21 of pivoting support 2 and the outer ring 22.Crotch 4 and rocking carrier 1 link to each other by bearing pin.One turns to oil cylinder 5 one ends to be fixed in vehicle frame 6 exterior bottom, oblique layout, with this fixed point that is connected in vehicle frame 6 as quiet pin joint; The other end links to each other with hinged seat 7 on the crotch 4, with this tie point as moving pin joint.The inner ring 21 of the pivoting support 2 that turns to oil cylinder 5 can drive crotch 4 and link to each other with crotch 4 rotates, and this inner ring 21 is along the rolling steel balls rotary oscillation, and the motion of crotch 4 is delivered on the rocking carrier 1, thereby makes the tire that is contained on the rocking carrier 1 realize go to action.This turns to the oil cylinder 5 oblique bottoms that are arranged in vehicle frame 6 outsides, and rotational fuel tank 5 moving pin joints are arranged based on the oil cylinder stroke near symmetrical, turn to oil cylinder 5 active forces that the arm of force of the front-wheel centre of gyration is distributed near best distribution; Rotational fuel tank 5 is fixedly hinged and a little is arranged in vehicle frame 6 outsides, and this has just avoided the motor wind scooper up hill and dale, has vacateed the space after rotational fuel tank 5 being fixedly hinged a little shift out, and just makes the Change In Design of wind scooper have possible; Like this not only improve the performance of breathing of engine cooling, also improved the maintainability that turns to oil cylinder 5 and engine radiator, reduced cost of production.In addition, turn to oil cylinder 5 quantity only to be one, therefore not only can reduce production costs, the dismounting during maintenance of maintenace points such as oil cylinder, radiator, the inconvenient problem of installation also have great convenience for the user, and help promoting the sale of product.
