Abstract
The utility model discloses a kind of cooling mechanisms of hub for electric vehicle formula motor, hub-type motor including motor shaft and with motor shaft rotation connection, hub-type motor includes shell and the motor body being arranged inside, the housing sidewall is equipped with through-hole, check valve is sealed and installed on the through-hole, when motor body internal temperature is excessively high, heat can be discharged outward by check valve, reduce temperature, and keep air pressure balance in motor, to keep motor performance more stable, extend the service life of motor, improves durability；The side wall of the shell, which is also enclosed, forms accommodating chamber equipped with retaining wall, and the check valve is located in accommodating chamber, and dust-separation device is set at the gas outlet of the check valve, is entered by dust-separation device barrier muddy water, dust and blocks check valve.
Description
Technical field
The utility model relates to electric vehicles, the especially cooling mechanism of hub for electric vehicle formula motor.
Background technique
Electric vehicle realizes that the driving to front and back wheel travels by motor, and hub-type motor uses wheel inner electric machine skill
Power, transmission and brake apparatus are all integrated on wheel hub by art；In the prior art, hub-type motor is by wheel rim and left and right side lid
Closed shell is formed, motor body is located in shell, heat can be generated when work done in operation, since heat can not be to outlet
It puts, when enclosure interior temperature rises to a certain degree, internal pressure increase just cannot achieve internal and external equilibrium, as vehicle uses
The growth of time, motor performance can be gradually reduced.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of heat dissipation machine of hub for electric vehicle formula motor
Structure.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of cooling mechanism of hub for electric vehicle formula motor, the hub-type including motor shaft and with motor shaft rotation connection
Motor, hub-type motor include shell and the motor body being arranged inside, and the housing sidewall is equipped with through-hole, close on the through-hole
Envelope is equipped with check valve, and the side wall of the shell, which is also enclosed, forms accommodating chamber equipped with retaining wall, and the check valve is located in accommodating chamber, institute
It states and is set with dust-separation device at the gas outlet of check valve.
The dust-separation device includes the flat outlet nozzle of the body of rubber being sleeved on check valve and the stretching of main body leading portion, described
It is gradually narrowed to middle part to end and forms elongate slot in two sides of outlet nozzle.
The end face of the accommodating chamber is covered with protective plate.
The check valve is two, and it is ipsilateral to be located at the shell.
The hub-type motor is disc brake type, and the side of the shell is equipped with the mounting base of installation disk brake, the accommodating chamber
For the inner cavity of mounting base.
The beneficial effects of the utility model are: the side wall of the utility model shell is equipped with the accommodating chamber of accommodating check valve,
When motor in operation, internal temperature increases, and the pressure inside motor increases with it, and opens outside the spool connection motor of check valve
Portion discharges heat by check valve, reduces temperature, and keep the air pressure balance in motor, thus keep motor performance more stable,
Extend the service life of motor, improves durability；It is further sleeved with dust-separation device at the gas outlet of check valve, prevents dust, muddy water or other
Foreign matter, which enters, blocks check valve.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is enlarged drawing at the B of Fig. 2.
Specific embodiment
Referring to figs. 1 to a kind of cooling mechanism of hub for electric vehicle formula motor of Fig. 3, including motor shaft 1 and with motor shaft 1
The hub-type motor 2 of rotation connection, hub-type motor 2 are equipped with including shell 7 and the motor body 8 being arranged inside, 7 side wall of shell
Through-hole 21 is sealed and installed with check valve 3 on through-hole 21, when motor in operation, internal work done generates heat, enables motor body 2
Internal temperature increases, and the pressure inside motor increases with it, and opens outside the spool connection motor body 2 of check valve 3, passes through
Discharge heat, reduction temperature keep the air pressure balance in motor body 2, to keep motor performance more steady to check valve 3 outward
It is fixed, extend the service life of motor and improves durability；The side wall of shell 7 also enclose equipped with retaining wall 23 formed accommodating chamber 5,3, check valve
In in accommodating chamber 5, capable of preventing because in vehicle travel process, wheel and foreign matter generate collision, damage damage to check valve 3；
It is set with dust-separation device 4 at the gas outlet of check valve 3, is entered by the barrier of dust-separation device 4 muddy water, dust and blocks check valve 3.
Preferably, dust-separation device 4 uses rubber material comprising body of rubber 41 and outlet nozzle 42,41 sets of body of rubber
It is realized on the gas outlet of check valve 3 and by elastic hose clamp and is fixedly mounted, two sides of outlet nozzle 42 are gradually narrowed to center
Elongate slot is formed to end, is in closed state under the elongate slot normal condition, dust is can effectively prevent and steam enters, avoid
At its gas outlet for accumulating in check valve 3, and due to rubber parts have elasticity, when enclosure interior pressure increase open check valve to
When outlet thermal discharge, elongate slot also deforms opening to a certain degree, to discharge internal pressure.
Further, it is also covered with protective plate 6 in accommodating chamber 5, prevents the foreign matters such as muddy water, stone from entering in accommodating chamber 5,
Check valve 3 is protected, and mitigates the work of dust-separation device 4, to reach better dustproof and waterproof effect.
Preferably, check valve 3 is two, and ipsilateral setting, the heat dissipation effect inside motor is effectively improved.
When the hub-type motor is disc brake type, the side of shell 7 is equipped with the mounting base 22 of installation disk brake, and accommodating chamber 5 is
The inner cavity of mounting base 22, check valve 3 are arranged in mounting base 22, no longer need to separately set other structures accommodating check valve 3, simplify knot
Structure.
