As shown in Figure 1, a kind of pure electric vehicle expanded letter mine car all hydraulic pressure steering-gear, including electric powered steering pump 2, steering valve group
4, accumulator 5, diverter 6, steering cylinder 7 and hydraulic oil container 8 are turned to, the hydraulic oil container 8 connects electric powered steering pump 2
Inlet port, the outlet connection of electric powered steering pump 2 turn to the P mouth of valve group 4, and the T mouth for turning to valve group 4 connects hydraulic oil container 8, switching valve
The AC of group 41Mouth, AC2Mouth is separately connected the oil outlet for turning to accumulator 5, and turning to accumulator 5 herein is two, turns to valve group 4
P1Mouth, T1Mouth be connected respectively diverter 6 P mouth, T mouthfuls, the R mouth of diverter 6, L mouthfuls be separately connected steering cylinder 7
Oil inlet, oil return opening；The steering cylinder 7 is by being arranged in the left steering power-assisted oil cylinder before vehicle at left and right sides of bridge T-type arm
71 and right turn power-assisted oil cylinder 72 form.Above-mentioned electric powered steering pump 2 is the prior art, can use model EHPS-
1730R7.5/36, the steering pump that producer is auspicious vertical Ruian auto parts and components Co., Ltd, can also be using the existing of other structures
Steering pump.Above-mentioned steering valve group 4 is also the prior art, and model IC-08*1-18, producer can be used for Eton hydraulic system
The steering valve group of (Jining) Co., Ltd can also turn to valve group using existing other with the same function.
Guarantee the cleannes of hydraulic system in order to avoid sucking pollution impurity, the electric powered steering pumps 2 inlet ports and liquid
It is connected with oil absorption filter 1 between pressure oil case 8, is connected with high-pressure filteration between 4 P mouthfuls of valve group of 2 outlet of electric powered steering pump and steering
Device 3.
Further, the R mouth of the diverter 6 separates two branches I, and two branches I are respectively connected to left steering power-assisted
The rod chamber of oil cylinder 71 and the rodless cavity of right turn power-assisted oil cylinder 72, the L mouth of diverter 6 separate two branches II, two branches
