Abstract
The invention discloses a power steering device for truck cranes. The power steering device comprises an upper cover (1), a tank body (2), an oil return pipe (6) and an oil inlet (9), wherein the inner cavity of the tank body (2) is provided with a filter (5) and an oil screen plate (8), the oil return pipe (6) is arranged in the filter (5), and the bottom of the tank body (2) is provided with the oil inlet (9) and an oil return port (7). The power steering device is characterized in that the top of the tank body (2) is provided with a spring press-mounting structure. By using the structure above, the power steering device disclosed by the invention has good sealing effect; and because the spring press-mounting structure is adopted, the internal space of the power steering device is greatly released, therefore, the filter with high filtration accuracy can be adopted, so that the size of a filtered grain is increased from original 100 mu m to 20 mu m, and the pass flow rate of hydraulic oil is increased to 80 L/min, and the hydraulic pressure of 1 Mpa generated in a steering system can be resisted.
Description
Technical field
This car hosit power steering gear (power steering oil tank) is used for the car hosit tool of full ground type, belongs to the motor turning technical field.
Background technology
Car hosit is when car hosit carries out steering operation with the power steering gear effect; For power steer provides a high-pressure and hydraulic oily petrol storage tank, Engine Mechanical can at first be converted into the hydraulic pressure ability through power steerig pump, and high-pressure and hydraulic oil is through power steering gear; The arrival direction machine; And can convert hydraulic pressure into mechanical energy and act on the steered wheel, thereby realize the light flexibly of steering operation, hydraulic oil finally returns and is stored in the power steering gear.Because steering swivel system is very high to the cleanliness level requirement of hydraulic oil, requires sealing and strainability to get well to steering oil reservoir, simultaneously air gate will be arranged; Devices such as oil level scale so that regularly check hand-dipping, add hydraulic oil; And deaeration, in order to avoid entrained air in the steering swivel system, the sensitieness that influence turns to; Because this power steering gear is applied to heavy-duty machineries such as car hosit, power steering gear self-filtering system should be able to be through the bigger flow oil pressure bigger with opposing.
The oil filling port of common steering oil reservoir, air gate are distributed in the top of steering oil reservoir respectively, are in communication with the outside in the feasible jar.Texture ratio is more loaded down with trivial details, and oad is bigger, is unfavorable for the layout of steering hardware, and under abominable operating mode, dust is prone to get in the pipe from air gate, influences the cleanliness level of power steering hydraulic efficiency pressure system.Ooze out and infiltrate dirt for fear of hydraulic oil, than higher, common steering oil reservoir only is equipped with seal ring between tank body and cover to the seal request of power steering gear, can not be in full force and effect prevent oozing out of steering hydraulic oil.
Summary of the invention
To the deficiency that prior art exists, the object of the present invention is to provide the car hosit power steering gear of simple and reasonable, compact conformation, easy to operation, good sealing effect.
Technical scheme of the present invention realizes in the following manner: a kind of car hosit power steering gear; Comprise loam cake, tank body, oil return pipe and oil inlet; The inner chamber of described tank body is provided with fil and filtering screen; Be provided with oil return pipe in the fil, the bottom labour of tank body has oil inlet and return opening, and it is characterized in that: the top of described tank body is provided with the pressure mounting of the spring structure.
Above-mentioned pressure mounting of the spring structure is by being that locking knob, ventilative little bowl and spring are formed, and locking knob is connected with oil return pipe.
Described ventilative little bowl is located at the seals at of locking knob, and spring is located between the epicoele of fil and tank body.
Adopt structure of the present invention; Good sealing effect can avoid hydraulic oil to ooze out and infiltrate dirt, and the hydraulic oil in whole steering hydraulic loop is cleaned; Guaranteed the performance of steering swivel system; Adopt ventilative little bowl to carry out closed processes owing to designed breather hole, make the air in the jar be able to discharge, can prevent entrained air in the hydraulic oil by actv..The sensitieness that has improved turning operation system also prevents under bad working environments simultaneously; Dust, sewage get in the tank body through breather hole, pollute hydraulic oil, owing to adopt the pressure mounting of the spring structure; Make the inner space obtain very big release; So can adopt the fil of high filtering precision, original filtering particle degree has been brought up to 20 μ m by 100 μ m: and make hydraulic oil bring up to 80L/min through flow, can resist the hydraulic coupling of the 1Mpa that produces in the steering swivel system.
Description of drawings
Fig. 1 is a main cutaway view of the present invention.
Fig. 2 is an outside drawing of the present invention.
The specific embodiment
Know by Fig. 1; A kind of car hosit power steering gear, this power steering gear assembly is made up of loam cake 1, tank body 2, dipstick cap 3, locking knob 4, fil 5, oil return pipe 6, return opening 7, filtering screen 8, oil inlet 9, dipstick 10, ventilative little bowl 11, spring 12 and mounting bracket 13.Oil return pipe 6 is welded on the return opening 7, return opening 7, and oil inlet 9, mounting bracket 13 are welded on 2 tank bodies.10 dipsticks and 3 dipstick cap weld togethers; Each parts that welding is good polish, electroplating processes; Each parts of handling well are assembled, during assembling 8 filtering screens are packed in 2 tank bodies, 5 fils of packing into successively again, 12 springs refill 1 loam cake; Put 11 ventilative little bowls, tighten 4 locking knobs and 3 dipstick caps respectively.
Locking knob 4 holddown springs 12 can well seal tank body 2 can avoid hydraulic oil to ooze out and infiltrate dirt, and the hydraulic oil in whole steering hydraulic loop is cleaned, and has guaranteed the performance of steering swivel system.Simultaneously also fix fil 5, breather hole has been arranged on the oil return pipe 6 and adopt ventilative little bowl 11 to carry out closed processes, can the air exhaustion in the jar can have been prevented entrained air in the hydraulic oil by actv..The sensitieness that has improved turning operation system also prevents under bad working environments that dust, sewage get in the tank body through breather hole, pollute hydraulic oil simultaneously.Owing to adopted the pressure mounting of the spring structure, can actv. reduce the project organization volume of power steering gear, make compact conformation, while easy for installation can adopt the fil 5 of high filtering precision.
