Description
Technical field
The utility model relates to hub motor drive system technical field more particularly to a kind of electric car planet carrier knots
Structure.
Background technique
On electric car, the drive form that motor, transmission mechanism, brake and cooling system etc. are combined together,
Referred to as hub motor drive system technology.Compared with traditional electric car, hub motor drive system will directly be moved hub motor
Power, transmission and brake apparatus are all integrated into hub for vehicle wheel, do not need traditional engine chamber, eliminate a large amount of mechanical transmissioning machines
Structure.Make vehicle Undercarriage structure greatly simplified simultaneously, automobile front chamber space increases, and suspended structure more preferably designs, drive mechanism letter
Change so that transmission efficiency is higher.Wherein, planet carrier structure is one of most important link.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of electric car planet carrier knot is provided
Structure, the structure is since planet carrier bearing internal external is arranged symmetrically, and the resultant radial force born is zero, and planet carrier is solely subjected to for transmission shaft
Torque avoids planetary gear gauge wear.
A kind of in order to achieve the above purposes, the technical solution adopted by the utility model is: electric car planet carrier structure, including
There are main shaft, gear shaft, planet carrier, end cap flange, end cap, sprocket wheel；Pass through main shaft bearing outside the main shaft and is set with sprocket drive spindle；Institute
Stating gear shaft is hollow shaft structure, and the shaft shoulder is provided on the gear shaft, passes through two groups of teeth wheel bearing outside gear shaft and is set with L shape
Annulus planet carrier；End cap flange has been bolted in the planet carrier end, which covers planet carrier and gear shaft
Between gap；Pass through bearing with end cover outside the planet carrier and be set with L shape end cap, which, which has been bolted, covers
The bearing cap in gap between end cap and planet carrier, by the shaft shoulder of the bearing cap and gear shaft that are fastened on end cap to planet carrier into
Row axially position；The planet carrier is outer to be set with sprocket wheel adjacent to end cap flange, which uses in the one side of end cap direction
It has been bolted brake block.
Preferably, the planet carrier is connected by spline structure with sprocket wheel, axially position is carried out to sprocket wheel.
The beneficial effects of the utility model are: the structure is since planet carrier bearing internal external is arranged symmetrically, the radial direction born
Resultant force is zero, and planet carrier is that transmission shaft is solely subjected to torque, avoids planetary gear gauge wear.
Detailed description of the invention
Attached drawing described herein is to be used to provide a further understanding of the present invention, and constitutes one of the application
Point, but do not constitute the restriction to the utility model.
Fig. 1 is planetary gear structure schematic diagram.
Wherein: 1 is main shaft, and 11 be main shaft bearing, and 2 be gear shaft, and 21 be gear axle bearing, and 3 be planet carrier, and 4 be end cap
Flange, 5 be end cap, and 51 be bearing with end cover, and 52 be bearing cap, and 6 be sprocket wheel, and 61 be brake block.
Specific embodiment
In conjunction with attached drawing, the utility model is described in further detail.
As shown, a kind of electric car planet carrier structure, includes main shaft 1, gear shaft 2, planet carrier 3, end cap flange
4, end cap 5, sprocket wheel 6；Sprocket drive spindle 2 is set with by main shaft bearing 11 outside the main shaft 1；The gear shaft 2 is hollow shaft structure,
It is provided with the shaft shoulder on the gear shaft 2, passes through two groups of teeth wheel bearing 22 outside gear shaft 2 and is set with L shape annulus planet carrier 3；It is described
End cap flange 4 has been bolted in 3 end of planet carrier, which covers the gap between planet carrier 3 and gear shaft 2；
L shape end cap 5 is set with by bearing with end cover 51 outside the planet carrier 3, which, which has been bolted, covers end cap 5
The bearing cap 52 in gap between planet carrier 3, by the shaft shoulder of the bearing cap 52 and gear shaft 2 that are fastened on end cap 5 to planet
Frame 3 carries out axially position；The planet carrier 3 is outer adjacent to being set with sprocket wheel 6 at end cap flange 4, and the sprocket wheel 6 is to 5 side of end cap
Brake block 61 has been connected in one side.
When it is implemented, the planet carrier 3 is connected by spline structure with sprocket wheel 6, axially position is carried out to sprocket wheel 6.
