Abstract
The utility model discloses a dual-pump hydraulic assistant steering device for a hybrid vehicle, which comprises a hydraulic assistant steering gear, an oil absorption pipeline, pressure pipelines, an oil return pipeline, an engine steering oil pump, a motor steering oil pump, a shuttle valve and a hydraulic oil storage tank, wherein an oil outlet pipe of the hydraulic oil storage tank is respectively connected with oil absorption ports of the motor steering oil pump and the engine steering oil pump by a three-way joint and the oil absorption pipeline; oil outlet ports of the motor steering oil pump and the engine steering oil pump are respectively connected with an oil inlet port of the shuttle valve by the pressure pipelines; an oil outlet port of the shuttle valve is connected with an oil inlet port of the hydraulic assistant steering gear by the pressure pipeline; and an oil return port of the hydraulic assistant steering gear is connected with an oil return port of the hydraulic oil storage tank by the oil return pipeline. The dual-pump hydraulic assistant steering device has the advantages of being driven by dual powers of a motor and an engine respectively, is energy-saving and has low noise.
Description
Technical field
The utility model belongs to automobile-used steering boost system technical field, especially relates to a kind of Hybrid Vehicle double pump hydraulic pressure assisted steering device.
Background technology
Present internal-combustion engines vehicle mainly is to lean on the engine drive power assistance pump for steering hydraulic power to be provided for the hydraulic pressure power-assisted steering device with hydraulic power-assist steering system; Its principle of work is: when engine running; The running of engine drive power steerig pump; The hydraulic oil storage tank is the power steerig pump fuel feeding, and power steerig pump provides oil pressure power through pressure line to hydraulic power steering gear; High-voltage oil liquid makes hydraulic power steering gear obtain servo driving power when steering wheel rotation, realizes easily turning to; When not turning to, hydraulic oil can flow back into the hydraulic oil storage tank through oil return line through the meta oil circuit of hydraulic power steering gear, realizes the off-load in whole loop; This system is simple and reliable; As long as the running of engine drive power steerig pump just can make to turn to not heavy, but for hybrid vehicle with pure motor driving pattern; If when pure motoring condition goes; The driving engine power steerig pump of not working just can not turn round, and steering boost system also just can't be used, and so just needs the hydraulic power-assisted steering system when driving engine is not worked, also can obtain hydraulic power.
Summary of the invention
The purpose of the utility model be to improve the deficiency of prior art and provide a kind of adopt double dynamically drive respectively, energy-conservation, Hybrid Vehicle double pump hydraulic pressure assisted steering device that noise is low.
The purpose of the utility model is to realize like this; A kind of Hybrid Vehicle double pump hydraulic pressure assisted steering device; Form by hydraulic power steering gear, inlet line, pressure line, oil return line, driving engine power steerig pump, motor steering oil pump, shuttle type valve and hydraulic oil storage tank; The oil outlet pipe that is characterized in the hydraulic oil storage tank is connected with the oil suction of driving engine power steerig pump with the motor steering oil pump respectively with inlet line through T-pipe joint; The oil outlet of driving engine power steerig pump and motor steering oil pump is connected through the oil inlet of pressure line with shuttle type valve respectively; The oil outlet of shuttle type valve is connected with the oil inlet of hydraulic power steering gear through pressure line, and the return opening of hydraulic power steering gear is connected with the return opening of hydraulic oil storage tank through oil return line.
Compared with present technology the utility model has following distinguishing feature and good effect: the utility model is that the oil outlet pipe of hydraulic oil storage tank is connected with the oil suction of driving engine power steerig pump with the motor steering oil pump respectively with inlet line through T-pipe joint; The oil outlet of driving engine power steerig pump and motor steering oil pump is connected through the oil inlet of pressure line with shuttle type valve respectively; The oil outlet of shuttle type valve is connected with the oil inlet of hydraulic power steering gear through pressure line; The return opening of hydraulic power steering gear is connected with the return opening of hydraulic pressure oil tank through oil return line; Just can realize that hybrid vehicle uses different power operated hydraulic power-assisted steering structures respectively when fuel oil goes with pure motor driving simply changing on the basis of traditional combustion engine automobile hydraulic electric power steering structure; The hydraulic circuit of the hydraulic power-assist steering system of hybrid vehicle in the fuel oil driving process is not changed; Guaranteed the reliability of conventional confguration; The oil suction of driving engine power steerig pump and motor steering oil pump is communicated with the hydraulic oil storage tank through inlet line and T-pipe joint respectively; Separately respectively from the oil suction of hydraulic oil storage tank; The oil outlet of driving engine power steerig pump and motor steering oil pump is connected with the oil inlet of hydraulic power steering gear with shuttle type valve through pressure line respectively; Shuttle type valve can be communicated with the oil inlet of hydraulic power steering gear by automatic oil outlet with the power steerig pump of working under the effect of flow, the oil outlet of out-of-run power steerig pump is sealed prevented that hydraulic oil from passing through out-of-run steering pump and flowing backwards, and the utility model does not need special hydraulic valve element, just can realize automaticallying switch without any need for control; Simple in structure, easy to operate, reliability is high, low cost of manufacture; Under electric-only mode, go, the electric powered steering oil pump can not exported excess hydraulic pressure oil with the constant rotational speed running and have good energy-saving effect, and can the low noise operation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
