A kind of oil pump assy that is used for automobile power steering
(1) technical field
The utility model relates to a kind of oil pump assy that is used for automobile power steering.
(2) background technology
Automobile (Other Engineering machinery) power steering system is made up of main parts size such as oil tank, power steerig pump, power steering (direction machine), straight and horizontal adjusting rod, bulb, oil pipes.The gear type power steerig pump is better than the vane type power steerig pump to the sensitivity and the reliability of oil cleanliness, so still have extensive market at passenger vehicle, heavy motor vehicle, construction machinery and equipment.Usually oil tank is fastened on the special stand of driving engine one side as independent parts, is connected with oil pipe between oil pump oil inlet and the oil tank.
This conventional confguration scheme has not only increased manufacturing cost (special stand, oil pipe, adaptor union, sealing member etc.), has also increased hidden danger of quality (seal failure between adaptor union causes oil pipe connecting portion oil impregnate and oil pump aspirated air etc.) simultaneously; Not only increase the weight of main frame, overall dimensions are increased, increased the difficulty of the compact general design of main machine structure.
(3) utility model content
It is a kind of integrated with oil tank and oil pump that technical problem to be solved in the utility model is to provide, and have the oil pump assy that is used for automobile power steering of the two original function.
A kind of oil pump assy that is used for automobile power steering comprises oil pump and oil tank, and described oil pump and oil tank are installed in the same housing, are provided with filter in the oil tank, and filter outlet is communicated with oil pump through pipeline.
Further, described filter also is provided with power steering rework solution inlet.
Adopt the technical solution of the utility model can make oil pump, becoming one of oil tank structure, saved parts such as fixed support, pump inlet pipe, adaptor union, sealing member, alleviated weight, reduced cost, thus the also corresponding driving efficiency that improved; Particularly reduced the link of railroad traction steering swivel system hidden danger of quality (oil pump oil inlet end), improved the reliability of power steering system, labour intensity and the safe driving that alleviates the engineer played positive role.
(4) description of drawings
Fig. 1 is the structural representation of the utility model oil pump assy.
(5) specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of oil pump assy that is used for automobile power steering comprises oil pump 1 and oil tank 2, and described oil pump 1 and oil tank 2 are installed in the same housing 3, are provided with filter 4 in the oil tank 2, and filter 4 outlets are communicated with oil pump 1 through pipeline 5.
Described filter 4 also is provided with power steering rework solution inlet 6.
