Description
Technical field
The utility model relates to a kind of Double-layer water cold type power steering oil reservoir, belongs to auto parts and components field.
Background technique
Commercial vehicle servosteering is mainly to drive by the circulation of hydraulic oil, reaches power-assisted labour-saving object.In whole closed liquid road, oil pump is for a long time in high speed operation state, and steering wheel is to carry out work according to road surface bend and road conditions.
Tradition oil tank generally includes tank body, oil inlet pipe and oil outlet tube.In the time that whole liquid road starts periodic duty, the temperature of hydraulic oil can progressively raise, normal duty, under general road state, oil temperature is conventionally between 50 DEG C～80 DEG C, and when road conditions complexity, particularly load-carrying is loaded in situation about exceeding standard, and oil temperature can be increased to rapidly 160 DEG C.In the time that oil temperature exceedes 80 DEG C, hydraulic pressure oil viscosity will significantly reduce, and decomposes to some extent, product gas, thereby oily quality is reduced, most critical be that Sealing in the whole liquid roads such as oil pump, steering wheel and oil tank just there will be deterioration phenomenon, will obviously reduce working life.
Therefore,, in the too high situation of oil temperature, there will be following problem:
(1) steering wheel and the oil pump that account for whole power steering system cost 90% can reduce working life greatly, occur leakage of oil, oil impregnate phenomenon, sometimes just must change less than three months.
(2) oil tank there will be the phenomenon of boiling, and can't stand that the pressure of the too high generation of oil temperature pops thereby hold, and confining liquid road is destroyed, and steering failure leads to serious accident.
Summary of the invention
The problem raising in order to solve oil temperature in liquid road, in the utility model Dui Ye road a key link---oil tank is transformed, carry out with circulating water cooling, thereby reach the object of controlling oil temperature.
The utility model for the technological scheme that its technical problem of solution adopts is: a kind of Double-layer water cold type power steering oil reservoir is provided, at least comprise tank body and be covered in the oil tank gland on tank body, tank body is outer to be surrounded by outer water pot, make to form airtight chamber between outer water pot and tank body, and outer water pot is exposed on the upper edge of tank body; Between the tank mouth of described oil tank gland and tank body, be provided with oil sealing; The lower end of centre bolt is connected with tank body inner bottom part center, and its upper end passes and is connected with gland nut from the through hole of oil tank gland center; 2 filter screen decks are arranged on centre bolt, and filter screen is arranged between 2 filter screen decks; Described filter screen deck, centre bolt and tank body are coaxial; Described tank body is provided with the oil inlet pipe and the oil outlet tube that are in communication with the outside, and outer water pot is provided with the water outlet and the water intake that are in communication with the outside.
Described water outlet is positioned at the below of outer water pot, and described water intake is positioned at the top of outer tank body.
Described tank body wall thickness is 0.4-3mm, and internal diameter is 80-400mm.
The wall thickness of described outer water pot is 0.4-3mm, and external diameter is 90-450mm.
The beneficial effect that the utility model has based on its technological scheme is:
(1) the utility model adopts double layers of tank body structure, does not change the former mounting type of conventional oil tank, can directly dock with former car oil pipe oil circuit;
(2) the utility model adopts circulating water, and wheel hub water spray system as existing in car, can directly utilize wheel hub water spray system, without increasing water resource system again; As there is no wheel hub water spray system, can make a small-sized water tank by oneself and add a little micro-water pump can to realize self-loopa cooling;
(3) the Double-layer water cold type power steering oil reservoir that utilizes the utility model to provide, oil temperature has obtained effective control, thereby make whole steering hydraulic system among a good temperature environment, after improving by this, steering wheel in power steering system, on average improve the working life of oil pump, high-pressure oil-tank etc. more than 5 times, reliability, Security improve greatly;
(4) the utility model cost is low, and cost only increases by 20% than traditional oil tank.
