The semi-integral steering system has the advantages that the system is applied to large tonnage, the system failure rate is reduced, and the emergency steering function is provided.
Description
Technical field:
The present invention relates to haul truck technical field, is a kind of with the emergent semi-monolithic formula steering swivel system turning to specifically, is applicable to wide dumper.
Technical background:
Wide dumper is to develop on the basis of road dump truck, because the weight on front axle of wide dumper increases, for the portability that guarantees to turn to, the configuration of its steering swivel system is all the integral automobile steering system that adopts a large cylinder diameter, then adds an external steering actuation cylinder; This kind of arrangement exists significantly not enough: 1, the working flow of Integral steering device is all generally 25 L/min at present, and operation pressure is 15MPa, has limited its application on large-tonnage vehicle; 2, in the time turning left with right-hand rotation, output torque is different; 3, owing to there being two deficiencies above, also cause the fault rate of deflector higher; 4,, because weight on front axle is larger, in the time that steering pump lost efficacy, can not provide emergent and turn to.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art, provide a kind of with the emergent semi-monolithic formula steering swivel system turning to; Mainly solve existing wide dumper steering swivel system fault rate high, cannot on large-tonnage dumping car, apply and without the emergent problem such as turn to.
Technical scheme of the present invention is: a kind of with the emergent semi-monolithic formula steering swivel system turning to, its special character is, on the driving engine of wide dumper, fixes steering pump, fixes steering oil reservoir on vehicle frame, fixing emergent steering pump on change speed gear box; Fixing emergent convertible valve and steering gear bracket on vehicle frame, on steering gear bracket, fix the deflector of semi-monolithic formula, the deflector of semi-monolithic formula is fixedly connected with steering drop arm upper end, and steering drop arm lower end is connected with the front end of steering track rod, and steering track rod rear end is connected with propons; Establish respectively left servo cylinder and right servo cylinder at the two ends of propons; To fix steering pump, the deflector of semi-monolithic formula, emergent convertible valve, steering oil reservoir, left servo cylinder, right servo cylinder and emergent steering pump connects by pipeline simultaneously.
Of the present invention a kind ofly have following outstanding substantive distinguishing features and marked improvement with the emergent semi-monolithic formula steering swivel system turning to compared with traditional Integral steering system: 1, more than the working flow of semi-monolithic formula deflector can arrive 40 L/min, make the application that it can be on large-tonnage vehicle; 2, turn left and output torque symmetry while turning right, it is more reasonable to design; 3, reduce the fault rate of steering swivel system; 4, increased emergent steering pump and emergent convertible valve and relevant pipeline, made it in the time that steering pump breaks down, vehicle still can be realized emergent turning to, and improves vehicle security.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the connection diagram of deflector of the present invention and steering drop arm;
Fig. 3 is the connection diagram of hydraulic tubing of the present invention.
The emergent steering pump 12 first oil inlet 13 first high-pressure pipe 14 second oil inlet 15 second high-pressure pipe 16 third high pressure pipe 17 first oil return pipe 18 first left-hand rotation oil pipe 19 second left-hand rotation oil pipe 20 first right-hand rotation oil pipe 21 second oil return pipe 22 second right-hand rotation oil pipes of the 1 steering pump 2 semi-monolithic formula deflector 3 steering drop arm 4 right servo cylinder 11 of the emergent left servo cylinder 10 of convertible valve 7 propons 8 steering oil reservoir 9 of steering gear bracket 5 steering track rod 6.
The specific embodiment:
For Comprehension and Implementation better, provide specific embodiment below in conjunction with accompanying drawing and describe the present invention in detail; Illustrated embodiment is only for explaining the present invention, not for limiting the scope of the invention.
Embodiment 1, referring to Fig. 1,2, by designing requirement, by steering pump 1 stationary engine relevant position, steering oil reservoir 8 is fixed on vehicle frame, and emergent steering pump 11 is fixed on change speed gear box relevant position, and emergent convertible valve 6 is fixed on vehicle frame; Steering gear bracket 4 is fixed on vehicle frame, semi-monolithic formula deflector 2 is fixed by bolts on steering gear bracket 4, steering drop arm 3 upper ends are fixed in semi-monolithic formula deflector 2 by spline, and lower end is connected with the front end of steering track rod 5, and steering track rod 5 rear ends are connected with propons 7; Left servo cylinder 9 and right servo cylinder 10 two ends are separately fixed at the two ends of propons 7;
Referring to Fig. 3, the first oil inlet 12 is communicated with to the A mouth of steering oil reservoir 8 and the T mouth of emergent steering pump 11; The first high-pressure pipe 13 is communicated with to the emergent P mouth of steering pump 11 and the P2 mouth of emergent convertible valve 6; The second oil inlet 14 is communicated with to the A mouth of steering oil reservoir 8 and the T mouth of steering pump 1; The second high-pressure pipe 15 is communicated with to the P mouth of steering pump 1 and the P1 mouth of emergent convertible valve 6; Third high pressure pipe 16 is communicated with to the emergent A mouth of convertible valve 6 and the P mouth of semi-monolithic formula deflector 2; The first oil return pipe 17 is communicated with to the emergent T mouth of convertible valve 6 and the B mouth of steering oil reservoir 8; The first left-hand rotation oil pipe 18 is communicated with to the Z mouth of semi-monolithic formula deflector 2 and the A mouth of left servo cylinder 9; The second left-hand rotation oil pipe 19 is communicated with to the Z mouth of semi-monolithic formula deflector 2 and the B mouth of right servo cylinder 10; The first right-hand rotation oil pipe 20 is communicated with to the Y mouth of semi-monolithic formula deflector 2 and the B mouth of left servo cylinder 9; Again the second oil return pipe 21 is communicated with to the T mouth of semi-monolithic formula deflector 2 and the B mouth of steering oil reservoir 8; Finally the second right-hand rotation oil pipe 22 is communicated with to the Y mouth of semi-monolithic formula deflector 2 and the A mouth of right servo cylinder 10; Form of the present invention a kind of with the emergent semi-monolithic formula steering swivel system turning to.
Of the present invention a kind of with the emergent semi-monolithic formula steering swivel system turning to, its principle of work: driven by engine steering pump rotates, change speed gear box drives emergent steering pump to rotate; When vehicle normally moves, high pressure oil is fed to emergent convertible valve by steering pump, then be fed to the deflector of semi-monolithic formula, is finally fed to left servo cylinder and right servo cylinder, promotes propons and rotate, and realization turns to; The hydraulic oil of emergent steering pump output is got back to steering oil reservoir through emergent convertible valve; When breaking down, steering pump can not provide enough high pressure oils, at flow during lower than a certain numerical value, and emergent convertible valve commutation, the high pressure oil of emergent steering pump is fed to the deflector of semi-monolithic formula, be fed to again left servo cylinder and right servo cylinder, promote propons and rotate, realize emergent turning to.
