And the 5th between groove 2313.The side wall and clamp spring 235 of such third groove 2322, which are collectively formed, limits the axial direction of roller 234
Position, plays the role of 234 retainer of roller in the prior art.But what the high efficiency one-way shaft in the utility model used
Component is less, and installation is simpler.
The breadth of clamp spring 235 can block the end of roller 234, and roller 234 is avoided to deviate from.In the breadth foot of clamp spring 235
Under the premise of enough width, deform and install in order to facilitate clamp spring 235, offered on the inside edge of clamp spring 235 multiple circumferentially spaced
The radial indentation 2351 of arrangement.
The tail portion of input shaft 21 offers blind hole 212, and internal tooth, the drive shaft 11 of motor 1 are provided on the inner wall of blind hole 212
End on have spline 111, the end of 1 drive shaft 11 of motor, which can match, to be inserted in blind hole 212, and 111 energy of spline
It is meshed with the internal tooth in blind hole 212, so then realizes the drive connection of motor 1 and output shaft 3.
Input shaft gear 211 is additionally provided on input shaft 21.Being provided on jackshaft 22 can nibble with 211 phase of input shaft gear
The jackshaft first gear 221 of conjunction and the jackshaft second gear 222 that can be meshed with the external toothing of freewheel clutch 23.
Electric vehicle walk when, motor 1 work drive motor 1 drive shaft 11 rotate, drive shaft 11 with driven input shaft 21 into
Row rotation, by input shaft gear 211 and the engagement of jackshaft first gear 221, jackshaft 22 rotates therewith, then passes through
Jackshaft second gear 222 and the engagement of 23 external toothing 232 of freewheel clutch drive the external toothing of freewheel clutch 23
232 are rotated.
After external toothing 232 is rotated by driving, ball 233 and roller 234 also roll therewith, when roller 234 is rolled to wedge groove
During the smaller one end of 2312 depth (one end of i.e. above-mentioned wedge groove 2312) position, by between roller 234 and ring gear 2
Extrusion friction acts on, and ring gear 231 is rotated synchronously with external toothing 232.When electric vehicle needs to slide, motor 1 is stopped, then
External toothing 232 stops operating, and under effect of inertia, output shaft 3 keeps rotation, and then ring gear 231 is driven to be rotated, this
When, roller 234 is rolled to larger one end of 2312 depth of wedge groove (other end of i.e. above-mentioned wedge groove 2312), roller 234 and interior
It is acted between gear ring 231 without extrusion friction, then ring gear 231 can keep rotary state, that is, realize sliding for electric vehicle.When work as
When motor-car needs braking, after output shaft 3 is braked the braking of hoof block 9, ring gear 231 stops operating, and external toothing 232 continues to turn
Dynamic, roller 234 is rolled to larger one end of 2312 depth of wedge groove (other end of i.e. above-mentioned wedge groove 2312), roller 234 at this time
It is acted between ring gear 231 without extrusion friction, then ring gear 231 will not be rotated with the rotation of external toothing 232, even if then
In the case where motor 1 is powered, electric vehicle can also realize braking.
In addition gear during the work time can heat production, and then hot gas is formed in the second installation cavity 42, with second
Hot gas air pressure in installation cavity 42 gradually rises, then needs to discharge the hot gas in the second installation cavity 42.According to the second installation
The difference in 42 space of chamber, may be used the air outlet structure of different structure.
As shown in Figure 8 and Figure 9, when 42 space of the second installation cavity is relatively large, in order to avoid while hot gas is discharged,
It will be discharged in second installation cavity 42 for lubricating the lubricating oil of each gear, the side for being molded over the second installation cavity 42 in the present embodiment
Air outlet structure on wall is specially：Air outlet structure is included along 42 radially-arranged 121 and second chamber of first chamber of the second installation cavity
Room 122 is isolated between first chamber 121 and second chamber 122 and is provided with partition board 123, and first chamber 121 passes through first through hole
124 are connected with the second installation cavity 42, and second chamber 122 is communicated with the outside by the second through-hole 125,121 He of first chamber
Second chamber 122 is connected by the third through-hole 126 being opened on partition board 123, and pressure-vent is provided in the second through-hole 125
Cap.After the hot gas air pressure in the second installation cavity 42 reaches the opening pressure of pressure-vent cap, pressure-vent cap is opened, then and second
Hot gas in installation cavity 42 passes through first through hole 124, first chamber 121, third through-hole 126, second chamber 122, second respectively
Through-hole 125 is discharged outside to.First through hole 124, the second through-hole 125 and third through-hole 126 are axially distributed in different levels
On face, i.e., air outlet structure is formed as a labyrinth structure, then will not be by the oil in the second installation cavity 42 while hot gas is discharged
Discharge.
As shown in Figure 10 and Figure 11, when 42 space of the second installation cavity is relatively small, air outlet structure could be provided as：Outlet
Structure includes being molded on the side wall of the second installation cavity 42 and to the cavity 421 that 42 direction of the second installation cavity is open, cavity 421
Bottom offers the stomata 422 being communicated with the outside, and pressure-vent cap is provided in stomata 422.And the one of the opening of cavity 421
Side has been extended chimb 423, which extends, and chimb to another side direction and to 42 direction of the second installation cavity
423 installation position, which can stop, gets rid of oil in cavity 421 in 2 rotation process of deceleration mechanism, but the hot gas generated is but
It can be entered in cavity 421 by the opening of cavity 421, and be discharged from stomata 422.
In order to enable the connecting wire cabling of connection motor 1 is convenient and beautiful.On the side wall of first installation cavity 41 in an axial direction
