Abstract
The utility model relates to an electric power steering motor for all-terrain vehicles. The electric power steering motor mainly comprises a stator, a rotor, a bearing, an end cover, a housing, a wiring board, and a junction box. The stator is composed of the housing and a magnetic shoe. The magnetic shoe is installed on the inner wall of the housing and is produced by neodymium iron boron permanent magnet material. The utility model discloses a brush permanent magnet DC motor for automobile electric power steering systems. Compared with a conventional electric power steering motor, the motor produced by tombarthite material has lower heat power, lower loss, and a longer service life than the conventional motor produced by ferrite material. A metallic shielding cover is disposed on the outer side of the housing so as to be capable of reducing magnetic leakage and increasing the magnetic field intensity of the whole apparatus. Unique waterproof design achieves higher reliability of the whole apparatus such that the motor has good application prospect.
Description
Technical field
The utility model relates to a kind of Novel DC electric power-assisted steering motor, especially can be applied to all-terrain vehicle electric booster steering device motor.
Background technology
Electronic technology is used widely in systems such as automobile steering device, engine, speed changer, brake and suspensions, vehicle electric power-assisted steering device progressively replaces conventional hydraulic power steering stgear at present, and electric booster steering device has become the study hotspot of world car technical development.Automobile electric power-assisted steering directly provides power-assisted with motor, and the size of power-assisted is controlled by electronic control unit (ECU).It can save fuel, and improve fail safe, and be conducive to environmental protection, be the new and high technology of the Hyundai Motor development topic that links closely, so just paid much attention to once appearance.Foreign Auto Companies started just automobile electric power-assisted steering have been started to research as far back as the eighties in last century, and through the development of more than 30 years, foreign technology reached its maturity.Over nearly 20 years, along with the development of electronic technology, the cost that significantly reduces automobile electric power-assisted steering has become possibility, adds that automobile electric power-assisted steering has series of advantages, makes it more and more be subject to people's favor.People have generally recognized the superiority of automobile electric power-assisted steering, so the market growth of automobile electric power-assisted steering is very fast now.
Traditional all-terrain vehicle is ferrite with the magnetic shoe material of electric power-aid steering electric machine, and the magnetic field intensity that this material can provide is limited, and magnetic loss is larger, magnetic energy product and the coercive force that can provide are less, the electric current passing through is very large, and loss and caloric value are also high, poor reliability.And due to without any shielding measure, cause the easy leakage field in magnetic field of device inside, the moment that can provide has further been provided.Under MODEL OVER COMPLEX TOPOGRAPHY, also very high to the water proofing property requirement of power-assisted steering motor, this has just directly caused reliability, practicality and the fail safe of traditional full landform electric power-aid steering electric machine to can not get ensureing.
Summary of the invention
The object of the invention is to: realize the full waterproof all-terrain vehicle electric power-aid steering electric machine that a kind of loss is low, caloric value is little, reliability is high.Short for improving traditional all-terrain vehicle electric power steering electrical machinery life, underpower, the problem such as water proofing property is poor.
For realizing above-mentioned functions, develop a kind of novel all-terrain vehicle electric power-aid steering electric machine, its basic composition comprises the parts such as stator, rotor, bearing, end cap, casing, terminal block, terminal box.Stator is made up of casing and magnetic shoe, and casing inner wall is installed magnetic shoe, and magnetic shoe is selected Nd-Fe-Bo permanent magnet material.Casing outside is metal-insulator radome, reduces the generation of leakage field, has improved motor internal magnetic field intensity.End cap assembly, between plug and end cap, adopts water-tight design between casing and end cap, can offer the operational environment that motor is good.
Improve as utility model, the armature of described full landform electric power-aid steering electric machine is by armature core, main shaft, armature coil and commutator form, armature core is fixed on main shaft, adopt epoxy coated insulation, stator is made up of casing and magnetic shoe, casing inner wall is installed magnetic shoe, magnetic shoe is selected Nd-Fe-Bo permanent magnet material, steel plate stretching structure in aggregates for casing and rear end cap, therefore make overall structure simple, front end housing is by aluminium alloy compression casting moulding, ball bearing is installed at two ends, main shaft supporting place, electromagnetic clutch is arranged on front end housing, commutator is pressed on main shaft, rotate together with main shaft.The utility model is mainly used in all-terrain vehicle electric boosting steering system.
Improve as utility model, metallic shield is equipped with in the casing outside of described full landform electric power-aid steering electric machine, can reduce the generation of leakage field, has effectively improved the magnetic field intensity of motor internal.Under identical moment condition, reduce the current strength of motor internal, can extend the useful life of motor.
Improve as utility model, the end cap assembly of described full landform electric power-aid steering electric machine, between plug and end cap, adopts water-tight design between casing and end cap, can offer the operational environment that motor is good.
Brief description of the drawings
Accompanying drawing is the structure chart of full landform electric power-aid steering electric machine;
In accompanying drawing: 1 is insulation shielding cover; 2 is casing; 3 is bearing; 4 is rotor assembly; 5 is neodymium iron boron (NdFeB) magnetic tile; 6 is end cap assembly; 7 is O type circle; 8 is waterproof plug and bundle assembly.
Embodiment
In the accompanying drawings, casing (2) and end cap assembly (6) are bolted, and both are equipped with the sealing of O RunddichtringO between joint portion, reach waterproof effect.
The outside of casing (2) is fastened with the leakage field that insulation shielding cover (1) is conducive to reduce system, reduces the electric current of motor under identical moment condition, increases the service life.The fixing neodymium iron boron (NdFeB) magnetic tile (5) in inside of casing (2), neodymium iron boron (NdFeB) magnetic tile (5) adopts rare earth material, makes the loss of steering gear lower, and caloric value is less.Bearing (3) press-fits in the end of casing (2), and rotor assembly (4) is assemblied in casing (2) inside by bearing (3).
The output of end cap assembly (6) has O type circle (7), and in the time that end cap assembly (6) is connected with electric booster steering device assembly, O type encloses sealing function.Between waterproof plug (8) leading-out terminal and end cap assembly (6), adopt rubber sleeve sealing, make leading-out terminal and end cap assembly (6) reach sealed waterproof effect.
