Technical field
The utility model belongs to automobile components in automobile industry, in particular to a kind of pure electric vehicle commercial vehicle electro-hydraulic
Servo steering system.
Background technique
Currently, the reason of with energy shortage and environmental problem, accelerate research and development of the China to new-energy automobile, especially
It is that pure electric automobile is greatly developed and applied.Pure electric automobile eliminates traditional engine, and steering pump is caused to lose
Power source can not provide electronic-controlled power steering, and since the weight on front axle of pure electric vehicle commercial vehicle is larger, existing low pressure EPS system
It is unable to satisfy the requirement of power steering.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned technical deficiency, a kind of achievable intelligent control is provided, output is stablized,
Safe and reliable pure electric vehicle commercial vehicle electronic hydraulic power-assisted steering system.
The utility model solve technical problem the technical solution adopted is that: pure electric vehicle commercial vehicle electro-hydraulic power-assisted steering system
System includes controller, steering pump, assist motor, electric motor end cap, its main feature is that, steering pump passes through the electricity of connector and assist motor
Generator terminal lid is fixedly connected, and gasket one, insulation sleeve are set on the connection bolt between steering pump and connector, in connector and electricity
Insulation spacer is equipped between the left side of generator terminal lid, steering pump, connector, insulation spacer are covered tightly by connection bolt and motor side
Gu together, the pump shaft of steering pump passes through the output axis connection of shaft coupling and assist motor, the two sides motor below assist motor
Damping base is symmetrically housed, the central axial and damping base of damping base is integrally formed with Shock-proof bolt, and damping base is logical on seat
It crosses Shock-proof bolt, gasket two and fastening nut to be fixed at the following four corners of motor cabinet, assist motor passes through three phase mains harness
It is connected with controller.
The beneficial effects of the utility model are: pure electric vehicle commercial vehicle electronic hydraulic power-assisted steering system uses intelligent control,
Output is steady；Using permanent magnet synchronous motor, high-efficient, long service life guarantees the operational safety of electronic power assist steering system, property
It can be reliable.The applicable range of steering pump is wide, reduces noise.Controller can realize that multistage speed controls, and reduce energy consumption, the control of multistage speed
Conventional steering system is avoided in high speed skidding and the appearance of vulgar non helping hand.

Specific embodiment
Embodiment, referring to attached drawing 1-3, pure electric vehicle commercial vehicle electronic hydraulic power-assisted steering system is the steering by vane type
It pumps the reserved mounting hole in 5 two sides and is fixed with connection bolt 3-1 by connector 3 and the electric motor end cap 2-1 of 2 left side of assist motor
Together.Connector 3 is installed on the main shaft of steering pump 5, is set on the main shaft of the steering pump 5 between connector 3 and steering pump 5
One 3-2 of gasket, insulation sleeve 3-3.Use shaft coupling 3-4 by steering pump 5 between connector 3 and the left side of electric motor end cap 2-1
The output shaft of main shaft and assist motor 2 connects.It is equipped between the connector 3 and electric motor end cap 2-1 of the periphery shaft coupling 3-4
Insulation spacer 3-5.The four corners of the motor cabinet 2-2- of two sides are symmetrically equipped with damping base 4, damping base below assist motor 2
4 central axial and damping base 4 is integrally formed with Shock-proof bolt 4-3, and damping base 4 is by rubber and bolt 4-3 injection molding.
Damping base 4 is fixed at motor cabinet 2-1 following four corners by Shock-proof bolt 4-3, gasket two 4-1 and fastening nut 4-2.Power-assisted
Motor 2 is connect by three phase mains harness with the motor three-phase connection plug 1-2 of controller 1, and controller 1 is equipped with vehicle signal
Plug 1-1 and vehicle high voltage power supply plug 1-3.
The working principle of pure electric vehicle commercial vehicle electronic hydraulic power-assisted steering system is: the damping base 4 in system is due to adopting
With rubber material, higher pressure can be born, flexible deformation effect is good, while reducing vibration, reducing noise.Controller 1 exports
Different frequencies, the revolving speed of control assist motor 2 realize different flow output, adjust the steering feel of driver.
