Abstract
The invention relates to a water-cooled hub motor structure. The water-cooled hub motor structure is characterized in that the water-cooled hub motor structure comprises a stator (1), a rotor assembly, a motor shaft (2) and a cooling water sleeve (3); the cooling water sleeve (3) is installed on the motor shaft (2), the cooling water sleeve (3) is provided with double helix circulating water flow channels (4), and the stator (1) is disposed on the outer circumferential side of the cooling water sleeve (3); the rotor assembly comprises a front end cover (6), a rear end cover (7) and a rotor (8); and the front end cover (6) and the rear end cover (7) form a machine shell, the rotor (8) is fixedly disposed on the inner side of the machine shell, and the rotor (8) is disposed on the outer circumferential side of the stator (1). The hub motor heat-radiation structure adopts the double helix circulating water flow channels, and, under the same volume, the heat-radiation capability of a motor is enhanced; and the two water channels are symmetrically distributed, so pressures of the shell are also symmetrically distributed, stress deformations of the shell are reduced, the shell is further thinned, the power density is improved, and the water-cooled hub motor structure has a greater cost advantage.
Description
Technical field
The present invention relates to technical field of motors, particularly a kind of water-cooled hub motor structure.
Background technology
Permanent magnetism hub drive system, because of the feature that its efficiency is high, energy density is large, progressively instead of AC Driving System in electric automobiles, and broader applications are in electric automobile.Tradition permanent magnetism wheel hub motor adopts internal rotor design usually, stator at external rotor interior, this motor and other motor AC asynchronous machine structural similarities, advantage is little with the difference of conventional motors, manufactures simply; Inferior position is that power density is not high, less economical.For this kind of problem, propose the design of electrical motor structure of improvement, adopt external rotor electric machine design, at internal rotor outside, to stator the advantage of this structure significantly can reduce the consumption of silicon steel sheet and copper, bring to power density; But there is volume to reduce, water capacity reduces, the problem of radiating effect difference.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide that a kind of structure is simple, the water-cooled hub motor structure of good heat dissipation effect.
Object of the present invention is achieved through the following technical solutions: a kind of water-cooled hub motor structure, it comprises stator, rotor assembly, motor shaft and cooling jacket, cooling jacket is arranged on motor shaft, cooling jacket offers double helix circulating water passage, stator is arranged on the outer circumferential sides of cooling jacket, stator is provided with excitation winding, rotor assembly comprises front end housing, rear end cap and rotor, front end housing and rear end cap composition casing, front end housing is rotated by bearing A and is arranged on motor shaft, rear end cap is rotated by bearing B and is arranged on motor shaft, front end housing is fixedly connected with by screw with rear end cap, rotor is fixedly installed on internal side of shell, rotor is arranged on stator outer circumferential sides.
Described cooling jacket is arranged on motor shaft by connecting key.
Described bearing A and bearing B is taper roll bearing.
The present invention has the following advantages: wheel hub motor radiator structure of the present invention adopts double helix circulating water passage, be installed in wheel for motor, the application background that axial dimension is very short, design two-way enters the current of scene 2, under the prerequisite of same uniform flow, shorten the time of flow of half, thus the heat-sinking capability doubled, under equal volume, strengthen the heat-sinking capability of motor; And two-way water channel is symmetrical, makes the pressure of housing also symmetrical, reduce the stress deformation to housing, thus further thinning housing, bring to power density, has stronger cost advantage.
