Abstract
The utility model discloses an insulating power steering oil supply device, which comprises an electromotor (1), a bolt insulating sleeve (2), an oil pump support (3), a coupling (4), a power steering pump (5), a coupling insulating pad (6), a flange insulating pad (7), a seat insulating plate (8) and a bracket (9). The insulating power steering oil supply device is characterized in that the coupling insulating pad (6) is additionally mounted inside the coupling (4), the flange insulating pad (7) is additionally mounted between a flange plate of the electromotor (1) and a flange plate of the oil pump support (3), the bolt insulating sleeve (2) is additionally mounted at a reamer hole position of a connecting bolt, and the seat insulating plate (8) is additionally mounted between the electromotor (1) and the bracket (9). The insulating power steering oil supply device has the advantages that the integral insulating power steering oil supply device has no outward electric leakage in electric leakage occurring in the electromotor by adding an insulation structure, thereby thoroughly eliminating safety hidden risk of electric leakage and greatly improving use safety.
Description
Technical field
The utility model belongs to the technical field of motor turning force aid system, particularly a kind of insulated type power steering feed apparatus.
Background technology
At present, widely used associated mode power steering feed apparatus on electric car, its electrical motor adopts coaxial coupler directly to be linked together with power assistance pump for steering.This power steering feed apparatus adopts the power steering feed apparatus of belt transmission to compare with oldfashioned, have compact conformation, the stable driving efficiency advantages of higher that reaches of in-use performance, so oldfashioned power steering feed apparatus is replaced by this new associated mode power steering feed apparatus.
But no matter be the oldfashioned power steering feed apparatus that adopts belt transmission, still all there is a general problem in this new associated mode power steering feed apparatus, and that is exactly the potential safety hazard of electric leakage.
Because with the carriage that electrical motor directly links to each other, coupler, parts such as oil pump bracket all are conductors,, bring great potential safety hazard just for thus the riding personnel of vehicle so when electrical motor leaked electricity, other parts of vehicle also can be leaked electricity.
The utility model content
At the problems referred to above, the utility model provides a kind of insulated type power steering feed apparatus.By on existing associated mode power steering feed apparatus, setting up several insulation sleeves, insulating mat and insulcrete and ingenious layout, electrical motor and other main parts size are insulated fully, thereby when electric leakage takes place in electrical motor, whole power steering feed apparatus can outwards not leak electricity, so just fundamentally eliminate the potential safety hazard of power steering feed apparatus electric leakage, greatly improved the safety that the power steering feed apparatus uses.
The purpose of this utility model is achieved in that by add insulating mat in coupler, between motor flange dish and oil pump bracket flange, add insulating mat, the place adds insulation sleeve at the attachment bolt articulation hole, between electrical motor and carriage, add insulcrete, electrical motor and other main parts size are insulated fully, thereby when electric leakage took place electrical motor, whole power steering feed apparatus can outwards not leak electricity.
The preferred polyformaldehyde of described bolt insulation sleeve material therefor, described insulcrete material therefor preferred epoxy.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment
Fig. 1 shows concrete structure of the present utility model, and it comprises: electrical motor (1); Bolt insulation sleeve (2); Oil pump bracket (3); Coupler (4); Power assistance pump for steering (5); Coupler insulating mat (6); Flange insulating mat (7); Base insulcrete (8); Carriage (9).
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated:
In coupler (4), add coupler insulating mat (6), make the main shaft of electrical motor (1) and the spindle insulating of power assistance pump for steering (5); Between electrical motor (1) flange and oil pump bracket (3) flange, add flange insulating mat (7), make mutually insulated between the mounting flange of electrical motor (1) and oil pump bracket (3); Add bolt insulation sleeve (2) at the articulation hole place of attachment bolt, when electrical motor (1) leaked electricity, tie bolt was charged, but because the existence of insulation sleeve makes that oil pump bracket (3) is not charged; Add insulcrete (8) between electrical motor (1) and the carriage (9), make mutually insulated between electrical motor (1) and the carriage (9).
By above-mentioned layout, make electrical motor (1) and other main parts size insulate fully to insulation system.When electrical motor (1) leaked electricity, the connection electricity can not take place in main parts size carriage (9), oil pump bracket (3) and power assistance pump for steering (5), thereby had guaranteed the safety in utilization of whole power steering feed apparatus.
Claims (3)
1. insulated type power steering feed apparatus, it comprises: electrical motor (1); Oil pump bracket (3); Coupler (4); Power assistance pump for steering (5); Carriage (9) is characterized in that: add coupler insulating mat (6) in described coupler (4); Between described electrical motor (1) flange and oil pump bracket (3) flange, add flange insulating mat (7); Add bolt insulation sleeve (2) at the articulation hole place of tie bolt; Between described electrical motor (1) and carriage (9), add insulcrete (8).
2. insulated type power steering feed apparatus as claimed in claim 1 is characterized in that, the preferred polyformaldehyde of described bolt insulation sleeve (2) material therefor.
3. as any described insulated type power steering feed apparatus in the claim 1 to 2, it is characterized in that described insulcrete (8) material therefor preferred epoxy.
