Abstract
The utility model provides an internal-external double-overflowing circulating type automotive power-assisted steering vane pump. The steering pump mainly consists of an oil absorbing and pressing region of the steering pump, a flow control damping hole, a pressure control damping hole, a safety valve, an internal circulating pipeline, an external circulating pipeline, an oil inlet, an oil outlet and an oil overflowing port. On the base of the internal circulating steering pump, the steering pump is provided with the oil overflowing port, and the oil overflowing port is communicated with an internal circulating oil way and is directly connected with an oil retuning tank, so that the internal circulating oil way is provided with a new oil way which is directly connected with the oil retuning tank to form into an external circulating oil way, therefore the pump realizes the internal-external double circulation and achieves the aim of reducing the temperature of steering pump. Furthermore, a part of hydraulic oil which continues the internal circulation plays a part in compensating the oil quantity at the same time.

Background technology
Boosting pump for car steering is applied to the automobile power steering system, for power steering system provides pressure oil-source, alleviated chaufeur steering operation strength at repeated alternation, improved the safe reliability of steering swivel system, the principle of work of steering pump is to utilize the blade-type pump basic functional principle, increase flow control principle and pressure control principle again, thereby stablized the delivery rate and the delivery pressure of steering pump.Present homemade truck steering pump adopts internal-circulation type more, also there is few part to adopt outer circulation type, the internal-circulation type steering pump has two pipelines of turnover oil, the hydraulic oil that surpasses dominant discharge is in the steering pump inner loop, for the oil-feed deficiency certain replenishing arranged, but crossing multicycle hydraulic oil, inside can convert the pressure of liquid to heat energy, caused the steering pump temperature build-up, when temperature is too high, just cause the steering pump wearing and tearing easily, especially in the mine, the building site, operating mode rugged environments such as battle field, the service life of the steering pump of dumping car is very low, and the outer circulation type steering pump is Duoed an oil spilling pipeline than interior circulation, and the hydraulic oil that surpasses dominant discharge flows back to oil tank by oil spill pipe, compare interior circulation, because many pipeline heat radiations, the temperature of outer circulation steering pump will be hanged down and interior circulation greatly, helps prolonging the life-span of steering pump, but, just enough locus need be arranged on automobile because many pipelines connect.
The utility model content
The purpose of this utility model provides a kind of circulating motor turning power-assisted of inside and outside double overflow blade-type pump that steering pump drop in temperature, fault rate are reduced.
Technical solution of the present utility model is: the circulating motor turning power-assisted of inside and outside double overflow blade-type pump is inhaled laminated oil zone 2 by steering pump, flow control damping hole 3, pressure control damping hole 5, safety valve 6, flow stabilizing valve 7, inner loop pipeline 8, external circulation line 9, oil inlet 10, oil outlet 11 and oil spilling mouth 12 are formed, the oil suction district that steering pump is inhaled laminated oil zone 2 links to each other with oil tank 1, flow control damping hole 3 and flow stabilizing valve 7 parallel connections, both link to each other with steering pump suction laminated oil zone 2 laminated oil zones simultaneously, automobile steering device 4 and 5 parallel connections of pressure control damping hole, both link to each other with flow control damping hole 3 oil outlet ends simultaneously, safety valve 6 links to each other with pressure control damping hole 5 rear ends, inner loop pipeline 8 connects steering pump and inhales laminated oil zone 2, external circulation line 9 connects oil tank 1, inner loop pipeline 8 and external circulation line 9 parallel connections, both are connected with flow stabilizing valve 7 with safety valve 6 simultaneously, oil outlet 11 connects automobile steering device 4 and flow control damping hole 3, oil inlet 10 connects steering pump and inhales laminated oil zone 2 and oil tank 1, and oil spilling mouth 12 connects external circulation line 9 and oil tank 1.
It is oily from oil tank 1 oil suction and pressure by volume-variation that steering pump is inhaled laminated oil zone 2, hydraulic oil by flow control damping hole 3 output constant current amounts, hydraulic oil surpasses dominant discharge, open flow stabilizing valve 7, the hydraulic oil that surpasses dominant discharge enters inner loop pipeline 8 and external circulation line 9, the hydraulic oil that a part surpasses dominant discharge directly flows back to oil tank 1 by external circulation line 9, and a part enters steering pump by inner loop pipeline 8 and inhales the additional oil-feed in laminated oil zone 2 oil suction districts, realizes inside and outside two circulation.
The utility model is on the steering pump basis of inner loop mode, on the steering pump pump housing, increase the oil spilling mouth, the oil spilling mouth communicates with interior circulating oil path and directly is linked back oil tank, thereby on interior circulating oil path, open the new oil circuit oil tank that directly is linked back and form the outer circulation oil circuit, make carry out in an on-cycle hydraulic oil part be that the outer circulation oil circuit directly flows back to oil tank by new oil circuit, thereby realize inside and outside two circulation, reach the purpose that has reduced the steering pump temperature, circulation hydraulic oil had played the effect of additional oil mass simultaneously in a part continued.The utility model can make the same steering pump of same driving engine that more selection has been arranged when adorning different vehicles, in the dress dumping car, open the overflow hydraulic fluid port, while is also deposited interior outer circulation, reduced the temperature of steering pump, also replenished certain oil mass by interior circulation, when adorning general bogie, can close the oil spilling mouth, thereby become circulation steering pump in the mono-, save the locus.
The beneficial effect that the utility model reached is: satisfying the power-steering while, reducing the temperature of steering pump, also remedying the situation of steering pump oil-feed deficiency.Make the same steering pump of same driving engine that more selection arranged when adorning different vehicles.
