The second mounting block 204 has a hollow block 205. A second limiting rod 208 is arranged between the inside of the hollow block 205, a clamping rod 209 is arranged between the insides of the two limiting holes 207, two symmetrical limiting blocks 210 are arranged between the second mounting block 204 and the hollow block 205, four connecting plates 211 are fixed to the outer wall of the shell 201, limiting grooves 212 are arranged on the opposite sides of the two limiting blocks 210, a fan blade 214 is arranged at one end of the T-shaped rod 213, a fixing shell 215 is installed at one end of the T-shaped rod 213, and the two limiting blocks 210 and the first limiting block 204 are provided with a plurality of connecting plates 211, and the fixing shell 215 is arranged at one end of the T-shaped rod 213. The two limiting rods 208 are connected by bolts and nuts, and the four connecting plates 211 are divided into two groups. Each limiting block 210 is respectively located between each group of connecting plates 211. The two ends of the clamping rod 209 are respectively located inside the two limiting grooves 212. One side of the fan blade 214 is against the surface of the fixed shell 215. The clamping rod 209 is movably sleeved between the inside of the circular holes of the two first limiting rods 206. The fan blade 214 is inside the shell 201. One side of the two first mounting blocks 203 is against the surface of the clamping rod 209. Contact, the electric drive axle mechanism 1 includes a differential assembly 101, a dual-axis motor 109 is installed on the differential assembly 101, the dual-axis motor 109 is inside the housing 201, two first limit rods 206 and the second limit rod 208 are fixed on the surface of the differential assembly 101, the surfaces of the two first mounting blocks 203 and the surfaces of the second mounting blocks 204 are in contact with the surface of the differential assembly 101, and the end of the T-bar 213 close to the dual-axis motor 109 is installed with the auxiliary output end of the dual-axis motor 109.

[0024] In this embodiment, when the new energy vehicle starts and is traveling on the road, the auxiliary output end of the dual-axis motor 109 that is started at this time (the main and auxiliary output ends of the dual-axis motor 109 are in forward rotation, that is, the new energy vehicle is traveling forward) will rotate, and then drive the T-shaped rod 213 connected thereto to rotate, and then the rotating T-shaped rod 213 will drive the fan blades 214 fixed on the T-shaped rod 213 to rotate with the cooperation of the fixed shell 215, and then the rotating fan blades 214 will drive the air inside the shell 201 (that is, use the flowing air to take away the heat generated by the dual-axis motor 109 when it is working and dispersed to the shell, thereby realizing the cooling operation of the dual-axis motor 109) to the porous sheet 202 , and then pass through the through holes of the porous sheet 202 and be discharged into the environment.

At this time, each moving limit block 210 will drive the corresponding limit slot 212 to move. When the two limit When the blocks 210 are completely removed from the corresponding set of connecting plates 211, the clamping rod 209 is then pulled out from between the inside of the two limiting holes 207. When the clamping rod 209 completes the removal operation, the shell 201 is moved again. At this time, the moving shell 201 will drive the porous sheet 202 to move. At the same time, the moving shell 201 will also drive the two first mounting blocks 203 and the second mounting blocks 204 to move on the corresponding first limiting rods 206 and second limiting rods 208 respectively. When the two first limiting rods 206 and the second limiting rods 208 are separated from the corresponding first mounting blocks 203 and second mounting blocks 204 respectively, the staff can now perform maintenance operations on the dual-axis motor 109.

[0025] Embodiment 2: According to Figure 1-Figure 5 and Fig. 9As shown, the electric drive axle mechanism 1 includes a differential assembly 101, a motor controller 102 is installed on the surface of the differential assembly 101, a connecting shell 103 is fixed to both end surfaces of the differential assembly 101, and a cover plate 104 is installed on the opposite sides of the two connecting shells 103, and two symmetrical connecting blocks 105 are fixed on the surface of the differential assembly 101, and two groups of mounting holes 106 are opened on the top of each connecting block 105, and the number of each group of mounting holes 106 is two, and a fixed Ring 107, a group of connecting pieces 108 are fixed on the surface of the differential assembly 101, and the number of each group of connecting pieces 108 is two. A dual-axis motor 109 is installed on the differential assembly 101, and the dual-axis motor 109 is electrically connected to the motor controller 102. The main output end of the dual-axis motor 109 is installed with the main shaft end of the differential assembly 101. The opposite sides of the two cover plates 104 are fixed with protective sleeves 110. The two transmission ends of the differential assembly 101 are fixed with rotating shafts 111, and the two rotating shafts 111 pass through the first bearing The first gear 112 is fixedly sleeved on the outer surfaces of the two rotating shafts 111, and the opposite ends of the two rotating shafts 111 are respectively rotatably embedded in the opposite sides of the two cover plates 104, and the opposite sides of the two cover plates 104 are rotatably embedded with the first rotating rods 113, and the opposite ends of the two first rotating rods 113 are respectively rotatably embedded in the inner walls of the two connecting shells 103, and the outer surfaces of the two first rotating rods 113 are fixedly sleeved with the second gear 114, and the interiors of the two connecting shells 103 are respectively connected by the first rotating rods 113. The two bearings are rotatably connected with a second rotating rod 115, and a transmission shaft 116 is fixed to the opposite ends of the two second rotating rods 115. The opposite ends of the two transmission shafts 116 are movably sleeved in the through holes of the two cover plates 104, and the opposite ends of the two transmission shafts 116 are movably sleeved in the inside of the two protective covers 110. A transmission gear 117 is installed on the two second rotating rods 115, and the teeth of the first gear 112 are meshed with the teeth of the second gear 114, and the teeth of the second gear 114 are meshed with the teeth of the transmission gear 117.

[0026] In this embodiment, when the new energy electric drive axle is needed, the entire new energy electric drive axle is first installed at the position where the new energy electric drive axle is installed on the new energy vehicle by using the fixing bolts, anti-skid nuts, connecting blocks 105, mounting holes 106 and fixing rings 107. Then the motor controller 102 is connected to the whole vehicle controller of the new energy vehicle. Then, two protective covers 110 and prepared components (such as wheel hub mounting frames) are used to dock the two drive shafts 116 with the two wheel hubs respectively. When the new energy electric drive axle is installed and needs to be started, when driving on the road, the driver in the cab can use the whole vehicle controller, the battery on the new energy vehicle and the motor controller 102 (which can accurately control the motor's speed, torque, rotation direction and other parameters to improve the driving experience) to start the dual-axis motor 109. At this time, the main output end of the started dual-axis motor 109 will drive the main shaft end of the differential assembly 101 to rotate. The rotating main shaft end will rotate the two transmission ends on the differential assembly 101 with the cooperation of the internal components of the differential assembly 101, and then each rotating transmission end will drive the corresponding first gear 112 to rotate with the cooperation of the rotating shaft 111, the corresponding connecting shell 103, the corresponding cover plate 104 and the first bearing connected thereto, and then each rotating first gear 112 will drive the corresponding second gear 114 to rotate with the cooperation of the corresponding connecting shell 103, the corresponding cover plate 104 and the corresponding first rotating rod 113, and then each rotating second gear 114 will drive the corresponding transmission shaft 116 to rotate with the cooperation of the corresponding connecting shell 103, the corresponding cover plate 104, the second bearing, the corresponding second rotating rod 115, the corresponding protective cover 110 and the corresponding transmission gear 117. When the two transmission shafts 116 rotate, the left and right wheels installed on the electric drive axle will rotate, thereby realizing the starting and driving operation of the new energy vehicle.

[0027] The effect and working principle of the entire mechanism are as follows: when the new energy electric drive axle is needed, the entire new energy electric drive axle is first installed at the position where the new energy electric drive axle is installed on the new energy vehicle by using the fixing bolts, anti-skid nuts, connecting blocks 105, mounting holes 106 and fixing rings 107, and then the motor controller 102 is connected to the whole vehicle controller of the new energy vehicle, and then the two protection covers 110 and the prepared parts (wheel hub mounting frame and other parts) are used to respectively connect the two transmission shafts 116 to the two wheel hubs. When the new energy electric drive axle is installed and needs to be started and driven on the road, the driver in the cab can use the whole vehicle controller, the battery and the motor controller on the new energy vehicle to control the vehicle. The dual-axis motor 109 is started with the cooperation of the motor 102 (which can accurately control the speed, torque, rotation direction and other parameters of the motor to improve the driving experience). At this time, the main output end of the started dual-axis motor 109 will drive the main shaft end of the differential assembly 101 to rotate, and the rotating main shaft end will rotate the two transmission ends on the differential assembly 101 with the cooperation of various components inside the differential assembly 101. Subsequently, each rotating transmission end will drive the corresponding first gear 112 to rotate with the cooperation of the rotating shaft 111 connected thereto, the corresponding connecting shell 103, the corresponding cover plate 104 and the first bearing. Then, each rotating first gear 112 will rotate with the corresponding connecting shell 103, the corresponding cover plate 104 and the corresponding first rotating rod 1 13, the corresponding second gear 114 is driven to rotate, and then each rotating second gear 114 will drive the corresponding transmission shaft 116 to rotate under the cooperation of the corresponding connecting shell 103, the corresponding cover plate 104, the second bearing, the corresponding second rotating rod 115, the corresponding protective cover 110 and the corresponding transmission gear 117. When the two transmission shafts 116 rotate, the left and right wheels installed on the electric drive bridge will rotate, that is, the starting and driving operation of the new energy vehicle is realized. When the new energy vehicle completes the start and is driving on the road, the auxiliary output end of the dual-axis motor 109 started at this time (the main and auxiliary output ends of the dual-axis motor 109 are forward, that is, the new energy vehicle drives forward) will rotate, and then drive the connected The T-shaped rod 213 rotates, and then the rotating T-shaped rod 213 will drive the fan blade 214 fixed on the T-shaped rod 213 to rotate with the cooperation of the fixed shell 215. Then the rotating fan blade 214 will blow the air inside the shell 201 (that is, use the flowing air to take away the heat generated by the dual-axis motor 109 when it is working and dispersed to the shell, thereby realizing the cooling operation of the dual-axis motor 109) toward the porous sheet 202, and then pass through the through hole of the porous sheet 202 and be discharged into the environment. At the same time, the low-temperature air in the environment will also continuously enter the interior of the shell 201 at the opening of the shell 201 near the first mounting block 203. Similarly, when the new energy vehicle is reversing, the auxiliary output end of the dual-axis motor 109 will reverse.That is, the fan blades 214 will also reverse, and the air inside the shell 201 will be discharged from the opening near the first mounting block 203 into the environment. At the same time, the low-temperature air in the environment will pass through the through holes of the porous sheet 202 and continuously enter the interior of the shell 201. When the new energy vehicle is traveling on an uneven road, the new energy vehicle will bump or jump up and down during driving. At this time, the shell 201 and the porous sheet 202 can be directly used to prevent the dual-axis motor 109 on the electric drive axle of the new energy vehicle from colliding with obstacles on the ground due to the large movement of the vehicle, thereby avoiding damage to the dual-axis motor 109. When the dual-axis motor 109 on the electric drive axle of the new energy vehicle needs to be repaired, it is only necessary to remove the bolts and nuts from between the two limit blocks 210, and then remove the two limit blocks 210 from between the corresponding set of connecting plates 211. At this time, each moving limit block 210 will drive the corresponding limit slot 212 to move. When the two limit blocks 210 are completely removed from the corresponding set of connecting plates 211, the clamping rod 209 is then pulled out from between the insides of the two limit holes 207. When the clamping rod 209 completes the removal operation, the shell 201 is moved again. At this time, the moving shell 201 will drive the porous sheet 202 to move. At the same time, the moving shell 201 will also drive the two first mounting blocks 203 and the second mounting blocks 204 to move on the corresponding first limit rods 206 and second limit rods 208 respectively. When the two first limit rods 206 and the second limit rods 208 are separated from the corresponding first mounting blocks 203 and second mounting blocks 204 respectively, the staff can perform maintenance operations on the dual-axis motor 109. When it is necessary to install the shell 201 back to the initial position, only the reverse operation is required.

[0028] Among them, the differential assembly 101 can make the left and right gears installed on the new energy electric drive axle rotate at different speeds, which can ensure that the new energy vehicle will not suffer excessive tire wear and vehicle loss of control when turning or driving on uneven roads. It is mainly composed of planetary gears, planetary wheel carriers, half-axle gears, planetary gear shafts, composite thrust washers, outer shells, shell covers, main shafts and other components.

[0029] Among them, the differential assembly 101, the motor controller 102 and the dual-axis motor 109 are all existing technologies, and their models can be selected according to actual conditions, and no further explanation is given here.
