Abstract
The utility model discloses the connection structure of the wheel hub and the motor of a split type electric car, wherein one axial end of the structure on the inner side of a wheel rim is radially and inwardly contracted so as to form a loop of first annular backstop. The other axial end of the structure on the outside of a motor is radially and outwardly expanded so as to form a loop of second annular backstop. The motor can just be inserted into the wheel rim. The axial end surface of the second annular backstop on the outside of the motor is blocked on the other axial end surface of the first annular backstop. A connecting piece is adopted for detachably and fixedly connecting the first annular backstop with the second annular backstop. According to the utility model, one axial end of the structure on the inner side of a wheel rim is radially and inwardly contracted so as to form a loop of first annular backstop, while the other axial end of the structure on the outside of a motor is radially and outwardly expanded so as to form a loop of second annular backstop. The first annular backstop and the second annular backstop are connected together through a connecting piece. The connection of the wheel hub and the motor of a split type electric car is simple in structure and convenient in installation and disassembly. Due to the adoption of the connection structure, the later-stage maintenance of the wheel hub of an electric car can be conveniently performed.
Description
Technical field
The utility model relates to a kind of wheel hub electric motor of electric vehicle connection structure, particularly a kind of split type wheel hub electric motor of electric vehicle connection structure.
Background technology
Tire on the electric vehicle hub is to be easy to bad part; Often need disassemble repairing; And want remove a tyre earlier wheel rim to be removed from motor; It is inboard at wheel rim that motor mainly leans on the end cap fixed clamp at present, and this kind structure is wanted very time-consuming of dismounting motor, and maintenance brings very big trouble to battery-driven car.
The utility model content
In order to remedy above deficiency, the utility model provides a kind of split type wheel hub electric motor of electric vehicle connection structure, simple in structure, the easy installation and removal of this split type wheel hub electric motor of electric vehicle connection structure.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of split type wheel hub electric motor of electric vehicle connection structure; The wheel rim inner shafts inwardly contracts to end footpath and forms a circle first ring-type backstop, and the motor outer shaft radially extends out to the other end and forms a circle second ring-type backstop, and motor be able to enough be inserted in the wheel rim; The axial end face backstop of the second ring-type backstop axial other end of the first ring-type backstop on wheel hub in the motor outside; Be provided with attaching parts, this attaching parts can be dismantled first and second ring-type backstop and be fixed together, when wheel rim is installed; External diameter location with motor; Put wheel rim, through attaching parts the two is fixed together then, install; During dismounting, the attaching parts that comes loose just can be taken down wheel rim, has made things convenient for the wheel hub motor remove a tyre like this.
Further improvement as the utility model; Said attaching parts can be dismantled the structure that is fixed together with first and second ring-type backstop: the first ring-type backstop is provided with at least three axial pass-through holes; The end face of the second ring-type backstop, one end is provided with the tapped bore coaxial with this through hole; Attaching parts is a bolt, and bolt passes the through hole of the first ring-type backstop and is spirally connected with the tapped bore of the second ring-type backstop, and bolt head backstop is in the first ring-type backstop, one end end face; This kind connection mode is easy to use, installs, dismantles quick.
As the further improvement of the utility model, the through hole on the said first ring-type backstop is the countersunk head through hole, and it is smooth that wheel rim and motor end face keep.
The useful technique effect of the utility model is: the utility model is through forming the first ring-type backstop that inwardly contracts in the footpath at the inboard end of wheel rim; The other end forms the second ring-type backstop that radially extends out in the motor outside; Through attaching parts first and second ring-type backstop is connected; This kind is simple in structure, installs, convenient disassembly, is convenient to the later period maintenance of electric vehicle hub.

The specific embodiment
Embodiment: a kind of split type wheel hub electric motor of electric vehicle connection structure, wheel rim 1 inner shafts inwardly contract to end footpath and form a circle first ring-type backstop 11, and motor 2 outer shaft radially extend out to the other end and form a circle second ring-type backstop 21; Motor 2 be able to enough be inserted in the wheel rim 1, and the second ring-type backstop, 21 axial end face backstops in motor 2 outsides, the first ring-type backstop, 11 axial other ends on wheel hub are provided with attaching parts 3; This attaching parts 3 can be dismantled first and second ring-type backstop and be fixed together; When wheel rim 1 was installed, the external diameter location with motor 2 put wheel rim 1; Through attaching parts 3 the two is fixed together then, installs; During dismounting, the attaching parts 3 that comes loose just can be taken down wheel rim 1, has made things convenient for wheel hub motor 2 remove a tyre like this.
Said attaching parts 3 can be dismantled the structure that is fixed together with first and second ring-type backstop: the first ring-type backstop 11 is provided with at least three axial pass-through holes; The end face of the second ring-type backstop, 21 1 ends is provided with the tapped bore coaxial with this through hole; Attaching parts 3 is a bolt; Bolt passes the through hole of the first ring-type backstop 11 and is spirally connected with the tapped bore of the second ring-type backstop 21; Bolt head backstop is in the first ring-type backstop, 11 1 end end faces, and this kind connection mode is easy to use, installs, dismantles quick.
Through hole on the said first ring-type backstop 11 is the countersunk head through hole, and wheel rim 1 keeps smooth with motor 2 end faces.
