Abstract
The utility model provides a car steering pressure oil tube structure. A pressure oil tube is designed into a combined structure of rigid tubes and a hose. The pressure oil tube adjacent to a steering pump and a steering gear adopts the hose, so the hydraulic noise and the vibration are effectively reduced and passengers feel comfortable. The rest parts of the pressure oil tube adopt the rigid tubes. The pressure oil tube is divided into three layers of structures in order to ensure the high-pressure oil liquid to work safely and normally; the outer layer is a chlorosulfonated polyethylene layer, the middle layer is a twisted nylon reinforcing layer and the inner layer is a polyacrylate rubber layer.
Description
Technical field
The utility model belongs to the automobile hydraulic electric power steering systems technology, is specifically related to a kind of motor turning pressure oil pipe structure.
Background technology
Hydraulic power steerig is the power driven oil pump with automotive engine, increase pilot control front-wheel steering strength by fluid power by turning to augmenter, thereby make handling maneuver light, and can suitably select the transmitting ratio of deflector, realize turning to requirement sensitive and ride safety of automobile.Turn to oil behind steering pump, oil pressure improves, and provides the powered piston through pressure oil pipe for deflector, promotes in the steering procedure laborsaving.
Pressure oil pipe is used to connect power steerig pump and deflector, and steering oil flows into deflector by pressure oil pipe after the oil pump pressurization, produce power-assisted.The pressure oil pipe that adopts on the cars on hand is commonly the hard tube structure, is easy to generate hydraulic noise and vibration.And the hard tube structure is single, bears the scarce capacity of oil pressure.
Summary of the invention
The purpose of this utility model is to provide a kind of motor turning pressure oil pipe structure at the deficiency of prior art existence, and oil pressure and pipe arrangement demand when satisfying the deflector normal operation reduce noise and vibration.
Technical solution of the present utility model is that pressure oil pipe is designed to by hard tube and the combined structure of flexible pipe, adopt flexible pipe at local pressure oil pipe near power steerig pump and deflector, can effectively reduce hydraulic noise like this and reduce vibration, satisfy occupant's traveling comfort, and the pressure oil pipe of remainder adopts hard tube.Pressure oil pipe is divided into three-decker, and skin is the chlorosulphonated polyethylene layer, and interlayer is a twisted shape nylon enhancement Layer, and internal layer is the lactoprene layer.
This structure has satisfied occupant's traveling comfort owing at the flexible pipe that has adopted suitable length near the place of power steerig pump and deflector, effectively reduce hydraulic noise like this and reduce vibration.The pressure oil pipe material is divided into three layers, can guarantee safety, the normal operation of high-voltage oil liquid.
Description of drawings
Fig. 1 is the hydraulic power steerig system diagram;
Fig. 2 is the pressure oil pipe arrangement plan;
Fig. 3 is the cross-section structure of pressure oil pipe.
Among the figure: 1 switches through interface, 5 power steerig pumps, 6 deflectors, 7 hard tubes, 8 skins, 9 interlayers, 10 internal layers that interface, 4 to oil pump connects deflector for flexible pipe, 2 for oil pipe clamp, 3
The specific embodiment
Referring to Fig. 1, pressure oil pipe is fixed on the vehicle body by 3 oil pipe clamps 1, and the interface that connects deflector 4 of pressure oil pipe is connected with deflector valve body 6, and the interface 2 that switches through to oil pump links to each other with power steerig pump 5, and pipe arrangement is close to vehicle body.
Referring to Fig. 2, pressure oil pipe is designed to adopt flexible pipe 3 at the local pressure oil pipe near power steerig pump and deflector, and the pressure oil pipe of remainder adopt hard tube 7 by the combined structure of hard tube 7 and flexible pipe 3.
Referring to Fig. 3, pressure oil pipe is made up of three-decker, and outer 8 is chlorosulphonated polyethylene layer (CSM), and interlayer 9 is twisted shape nylon enhancement Layers, and internal layer 10 is lactoprene layer (SCM).
Claims (2)
1, a kind of motor turning pressure oil pipe structure is characterized in that: pressure oil pipe is by hard tube and flexible pipe is combined constitutes, and adopt flexible pipe at the pressure oil pipe near the place that connects power steerig pump and deflector, and the pressure oil pipe of remainder adopts hard tube.
2, motor turning pressure oil pipe structure according to claim 1, it is characterized in that: pressure oil pipe is divided into three-decker, and skin is the chlorosulphonated polyethylene layer, and interlayer is a twisted shape nylon enhancement Layer, and internal layer is the lactoprene layer.
