Description
Technical Field
The utility model relates to a field of wheel limit motor, concretely relates to wheel limit is wheel hub unit for motor.
Background
The wheel edge motor realizes independent driving of the wheel by adopting a mode that the motor is arranged on the wheel edge. The hub unit for the existing wheel-side motor can bear smaller torque, so that the transmission performance of the bearing unit is poor, and the service life of the bearing is shorter.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a wheel hub unit for wheel limit motor, have simple structure, simple to operate's advantage.
The purpose of the utility model is accomplished through following technical scheme: the hub unit for the wheel-side motor comprises a bearing inner ring, a hub outer ring and a flange plate, wherein the hub outer ring is movably sleeved on the flange plate, and the bearing inner ring which is clamped with the flange plate in a groove type and is in limiting nesting is arranged between the hub outer ring and the flange plate; an outer raceway is arranged between the root part of the shaft neck of the flange plate and the outer ring of the hub, the outer raceway and the inner raceway arranged between the inner ring of the bearing and the outer ring of the hub form a double-row raceway for mounting a rolling body of the bearing, and the retainer is covered outside the rolling body of the bearing to fix the rolling body of the bearing; the bearing inner ring and the hub outer ring are connected and sealed through a magnetic sealing ring, and the flange plate and the hub outer ring are connected and sealed through a sealing assembly; a deep groove ball bearing is arranged in the flange plate, and the driving shaft is supported on the flange plate through the deep groove ball bearing.
As a further technical scheme, a sun wheel is sleeved on the outer diameter of the flange plate close to the inner ring of the bearing, and a protective steel wire is sleeved on the installation position of the sun wheel and the flange plate.
As a further technical scheme, the outer surface of the leading end of the flange plate is provided with an external spline for matching with a sun gear.
The utility model has the advantages that: through structural design, the obtained novel wheel hub unit for the wheel side motor can bear the maximum torque of not less than 800Nm, the transmission performance of the bearing unit can be effectively enhanced, the integration level is improved, and the installation difficulty is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Description of reference numerals: the device comprises a bearing inner ring 1, a hub outer ring 2, a flange plate 3, a magnetic sealing ring 4, a sealing assembly 5, a bearing rolling body 6, a retainer 7, a sun gear 8, a protective steel wire 9, a driving shaft 10 and a deep groove ball bearing 11.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example (b): as shown in the attached figure 1, the hub unit for the wheel rim motor comprises a bearing inner ring 1, a hub outer ring 2 and a flange plate 3, wherein the hub outer ring 2 is movably sleeved on the flange plate 3, and the bearing inner ring 1 which is in clamping groove type limiting nesting with the flange plate 3 is arranged between the hub outer ring 2 and the flange plate 3; an outer raceway is arranged between the root of a shaft neck of the flange plate 3 and the hub outer ring 2, the outer raceway and the inner raceway arranged between the bearing inner ring 1 and the hub outer ring 2 form a double-row raceway for mounting a bearing rolling body 6, and a retainer 7 covers the bearing rolling body 6 to fix the bearing rolling body; the bearing inner ring 1 and the hub outer ring 2 are connected and sealed through a magnetic sealing ring 4, and the flange plate 3 and the hub outer ring 2 are connected and sealed through a sealing assembly 5 (dust, muddy water and lubricating grease can be prevented from entering and overflowing); a deep groove ball bearing 11 (capable of bearing larger radial load and beneficial to stabilizing the relative position of the driving shaft 10 in the transmission process) is arranged in the flange plate 3, and the driving shaft 10 is supported on the flange plate 3 through the deep groove ball bearing 11; a sun wheel 8 is sleeved on the outer diameter of the flange plate 3 close to the bearing inner ring 1, and a protective steel wire 9 is sleeved on the installation position of the sun wheel 8 and the flange plate 3 (so that more curling cracks caused by surface discontinuity are reduced); the outer surface of the leading end of the flange 3 is provided with an external spline for matching with the sun wheel 8.
Through the in-service use test, the utility model discloses a carry out redesign to hub unit structure, the novel wheel edge motor that obtains can bear the maximum torque with hub unit ≧ 800Nm, effectively strengthens bearing unit's transmission performance, promotes the integrated level, reduces the installation degree of difficulty.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
