The system can be mounted on and applied to the conventional vehicle using a low-voltage storage battery; the low-voltage storage battery on the vehicle is used as a driving power source of the motor; the low-voltage hydraulic power-assisted steering system is easy to mount and high in suitability; and the power-assisted steering system implemented by combining motor driving and hydraulic control can meet requirements of a large vehicle on energy conservation and steering power.
Description
Technical field
The utility model relates to motor turning control technology field, is specifically related to a kind of automobile and low pressure electric hydraulic power-assisted steering system thereof.
Background technology
Automobile steering system is one of important composition system of automobile; The performance of steering swivel system directly has influence on the road-holding property of automobile, and it plays an important role for the safety traffic of guaranteeing vehicle, the personal safety that reduces traffic accident and protection chaufeur, the service conditions of improving chaufeur.
Existing steering swivel system comprises three types of hydraulic power-assisted steering, electron steering hydraulic power-assisted steering and electric boosting steering systems; Traditional hydraulic power-assist steering system is widely used because of its proven technique; But because it accomplishes steering operation through providing hydraulic booster more than needed to help chaufeur; Can't take into account the high demand of power steering when chaufeur hangs down low demand of power steering and low speed in the vehicle ' when the vehicle high speed; The electron steering hydraulic power-assist steering system that can be regulated the power-assisted size gradually replaces; The electron steering hydraulic power-assist steering system is experienced for the driver provides to drive better, yet the original power of its hydraulic booster still relies on driving engine, and therefore whole system still needs work when the manual steering demand.Electric boosting steering system is through motor and speed reduction gearing the variable steering power-assisted to be provided directly; Hydraulic structure has more existing fluid leakage problem to solve hydraulic efficiency pressure system to forgo fully; Only on the minority high-grade car, realize at present using; And be badly in need of a kind of saving energy consumption on the diesel-powered vehicles such as motorcoach and can provide with the power-assisted steering swivel system of speed, so the hydraulic power-assist steering system that low voltage motor drives can be research and development and application trend.
Summary of the invention
The purpose of the utility model is the above-mentioned shortcoming that exists to prior art; Provide a kind of simple in structure, manufacturing cost is lower, energy efficient and the variable power-assisted low pressure electric hydraulic power-assisted steering system that can be used for traditional motorcoach can be provided, and the vehicle that uses this system.
For realizing above-mentioned purpose, the utility model adopts following technical scheme: a kind of low pressure electric hydraulic power-assisted steering system comprises
Power supply;
Hydraulic Pump, delivery pressure fluid to steering swivel system pressure oil circuit;
Motor is used for driving and the modulated pressure pump;
Controller receives the Vehicular turn parameter signal, and outputs control signals to said motor; And
Steering hardware is converted into power-assisted power with oil liquid pressure; Said power supply adopts the Vehicular accumulator cell of 24V～48V, and said controller comprises control module and power model, and said power model adopts metal-oxide-semiconductor as driving switch.
The printed circuit board (PCB) of said power model adopts aluminium base.
The utility model also comprises following technical scheme:
A kind of automobile comprises the servo steering system of being convenient to the direction of operating dish, and this servo steering system is specially above-mentioned each described low pressure electric hydraulic power-assisted steering system.
But the low pressure electric hydraulic power-assisted steering system installation application of the utility model adopts low tension battery on the vehicle as the driving propulsion source of motor on the conventional truck of using low tension battery, simple installation, and applicability is high.
Adopt motor-driven can satisfy the demand of full size vehicle to energy-conservation and steering power with the servo steering system that combines to realize of fluid control.
Owing to make drive current strengthen as the servo-steering propulsion source low tension battery on the conventional truck, the power model of controller adopts aluminium base to improve radiating effect better.
