[0086] In some embodiments, as Figure 13 As shown, the universal joint transmission device 2 includes a first-stage universal joint 21 and a second-stage universal joint 22. The first-stage universal joint 21 includes an input shaft fork 211, an input cross shaft 212, and an elastic push rod 213. The second-stage universal joint 22 includes an elastic sleeve 221, an output cross shaft, and an output shaft fork. The input shaft fork 211 is hinged to one end of the elastic push rod 213 via the input cross shaft 212. The other end of the elastic push rod 213 is sleeved within the elastic sleeve 221. The two cannot rotate relative to each other but can only move relative to each other. The end of the elastic sleeve 221, away from the elastic push rod 213, is hinged to the output shaft fork via the output cross shaft. The end of the output shaft fork, away from the output cross shaft, is provided with a power column 223. The first-stage universal joint 21 enables the first change of direction of the input speed and torque, while the second-stage universal joint 22 enables the second change of direction of the input speed and torque. The universal joint transmission device can transmit the speed and torque output by the engine to the transmission device 3, realizing a flexible connection between the cockpit system 1 and the transmission device 3, making the vehicle more stable and safer during driving.
[0087] In some embodiments, as Figures 14 to 18As shown, the speed transmission device 3 includes a continuously variable transmission assembly 31, and the continuously variable transmission assembly 31 includes a power column 223, a driven column 312, a shift paddle 313, a flexible device 314, a reduction center wheel 315 and a front shell 316. The power column 223, the driven column 312, the shift paddle 313 and the flexible device 314 are arranged in the front shell 316. One end of the power column 223 is provided with a driving cone wheel 311, and the other end is provided with a power column shaft fork. A protrusion is provided in the middle of the power column shaft 224 of the power column shaft fork, which can cooperate with the sleeve shaft piece 222 of the output shaft fork 211 to form an output cross shaft. The contact part between the power column 223 and the power column shaft fork is provided with a flange for axial locking with the front shell 316. A driven bevel gear is sleeved onto the driven column 312. The conical friction surfaces of the driving bevel gear 311 and the driven bevel gear are tangential, achieving frictional transmission of speed and torque. Multiple layers of solid-solution paint are applied to the surfaces of the driving bevel gear 311 and the driven bevel gear to increase friction and strength. The flexible device 314 includes a flexible cross shaft 3141, a flexible sleeve rod 3142, and a flexible push rod 4143. One end of the flexible sleeve rod is connected to the driven column 312, and the other end of the flexible sleeve rod 3142 is hinged to one end of the flexible push rod 3143 via the flexible cross shaft 3141. A reduction center wheel 315 is located at the other end of the flexible push rod 3143 and is connected to the reducer 32. The speed shift paddle 313 is sleeved onto the driven column 312 and is used to drive the driven bevel gear to move axially, thereby changing the transmission ratio of the transmission device 3. The driven bevel gear is connected to the driven column 312 via a keyway 3123. A ball bearing is mounted at the end of the driven column 312, consisting of an inner ball bearing seat 3122 and an outer ball bearing seat 3121. The outer ball bearing seat 3121 has a guide groove, and the inner ring of the shift paddle 313 has a guide protrusion 3131 that mates with the guide groove. The ball bearing primarily supports the shift paddle 313, preventing wear between the paddle 313 and the driven column 312. The shift paddle 313 has coupling sections 3132 at each end, each connected to a motor mounted on the front housing 316. When the vehicle's driving state changes, the driver generates a corresponding electrical signal via the operating handle 1112. This signal is analyzed and calculated by the main control module and converted into a control signal, which controls the movement of the coupling section 3132 of the shift paddle 313, changing the diameter ratio of the friction cone surface and thereby altering the transmission ratio of the transmission 3. The two wheel assemblies are each equipped with a transmission device 3, which controls the rotation speed of the two wheels respectively, thereby controlling the acceleration and steering of the wheels.
[0088] In some embodiments of the present application, Figure 19As shown, the reducer 32 also includes a driven reduction wheel 321, a rear shell 323 and a fixed plate 324. The reduction center wheel 315 is meshed with the driven reduction wheel 321. The driven reduction wheel 321 is coaxially connected to the groove gear 322. The reduction center wheel 315 and the driven reduction wheel 321 are located in the rear shell 323. The fixed plate 324 is connected to the wheel rim. A support shaft is provided on one side of the fixed plate 324. The driven reduction wheel 321 and the groove gear 322 are rotatably connected to the support shaft. Figure 20 As shown, the outer edge of the grooved gear 322 is an oil storage groove 3221 with a certain depth, and a number of transmission columns 3222 are arranged to replace the gear teeth for transmission. The grooved gear 322 is used to ensure that there is always lubricating oil at the meshing point between the gear and the wheel, which can reduce the impact on the gear and also play a dust-proof role.
[0089] In some embodiments of the present application, Figure 21 and Figure 22 As shown, the shock absorber 42 includes a liquid storage rod 421, a return hydraulic rod 422 and a damping spring 423. One end of the return hydraulic rod 422 is sleeved in the liquid storage rod 421, and the damping spring 423 is sleeved outside the return hydraulic rod 422. An inner end cover 4211 is provided on the end of the liquid storage rod 421 away from the return hydraulic rod 422, and an outer end cover 4224 is provided on the end of the return hydraulic rod 422 away from the liquid storage rod 421. A locker 1115 is provided on the cabin body 11, and the locker 1115 is connected to the inner end cover 4211. A tension and pressure platform 4112 is provided on the inner side of the elastic beam wall 4113, and the tension and pressure platform 4112 is connected to the outer end cover 4224. The reservoir rod 421 and the return hydraulic rod 422 are precisely matched, sealing the oil in the annular groove 4212 within the reservoir rod 421. The return hydraulic rod 422 is provided with an immersion hole 4221 and a liquid guide hole 4223, allowing a small amount of oil to flow through this liquid path into the internal cavity of the return hydraulic rod 422. When the return hydraulic rod 422 is pressed against the reservoir rod 421, the oil can initially only enter the cavity through the liquid guide hole 4223. As the displacement continues to increase, more oil flows into the cavity from the return oil hole 4222, and the resistance gradually decreases. If the cavity of the return hydraulic rod 422 is used as a reservoir, the situation is reversed. The damping spring 423 is installed between the return hydraulic rod 422 and the outer end cover 4224 to reset the shock absorber 42. The elastic rear frame 411 is connected to the wheel assembly via a positioning ring 4111. When braking, the motor controls the shock absorber 42 to stretch outward a certain distance, causing the front end of the elastic rear frame 411 to open, resulting in an opening angle θ between the two wheel assemblies. This decomposes the vehicle's speed into lateral and longitudinal directions. The lateral direction is the axis of rotation of the vehicle, and the longitudinal direction is the forward and backward direction of the vehicle. The lateral speed is absorbed by the elastic rear frame 411, which also causes the opening angle of the elastic rear frame 411 to continuously expand. The longitudinal speed decreases as the opening angle increases.
[0090] In some embodiments, Figures 23 to 26As shown, the lock-ring brake device 43 includes a power spline shaft 431, a power lock ring 432, a driven lock ring 433, a brake paddle 434, a driven spline shaft 435, an internally toothed lock buckle 436, and an elastic band 437. One end of the power spline shaft 431 is connected to the engine 71, and the other end is connected to the power lock ring 432. The driven lock ring 433 is connected to one end of the driven spline shaft 435, and the other end of the driven spline shaft 435 is connected to the input shaft fork 211. The brake paddle 434 is mounted on the power lock ring 432 and the driven lock ring 433 and can slide in the axial direction. The internally toothed lock buckle is mounted on one side of the driven lock ring 433. The teeth on both sides of the inner and outer teeth at one end of the brake paddle 434 are chamfered to form pointed inner teeth 4343 and pointed outer teeth 4342. The pointed teeth can reduce the resistance encountered by the brake paddle 434 during movement. The other end of the brake paddle 434 lacks internal and external teeth, but instead has multiple rectangular holes cut into it to serve as a paddle buckle 4341. The external teeth of the brake paddle 434 are only half the length of the internal teeth, corresponding to the internal teeth of the internal tooth lock buckle 436. The internal teeth 4362 at the top of the lock buckle are also chamfered, making the movement of the brake paddle 434 smoother. The cockpit system 11 is provided with a cabin elastic belt buckle 1126, and the internal tooth lock buckle is provided with a brake elastic belt buckle 4361. The elastic belt 437 is wrapped around the cabin elastic belt buckle 1126 and the brake elastic belt buckle 4361 to provide resistance for the lock ring type brake device 4343. During normal driving, the brake paddle 434 engages with the power lock ring 432 and the driven lock ring 433 at the same time. The power transmission route is from the power spline shaft 431 to the power lock ring 432, and then to the brake paddle 434. The inner teeth of the brake paddle 434 engage with the outer teeth of the driven lock ring 433 to transmit the power to the driven lock ring 433 until it reaches the driven spline shaft 435. During this process, the inner tooth lock buckle 436 does not obtain power. When braking, the brake paddle 434 moves axially toward the driven lock ring 433, and the brake paddle 434 is disengaged from the power lock ring 432 and no longer has a transmission function. At the same time, the brake paddle 434 is engaged with the inner tooth lock buckle 436. At this time, the power source is the remaining kinetic energy on the driven spline shaft 435. The power transmission route is from the driven spline shaft 435 to the driven lock ring 433, then to the brake paddle 434, and finally to the inner tooth lock buckle 436. The inner tooth lock buckle is provided with an elastic belt buckle 1126, and the elastic belt is respectively connected to the elastic belt buckle 1126 and the cabin frame 112 to provide resistance for the lock ring brake device 4343.The braking system 44 is composed of an elastic rear frame 411, a deceleration device 4141, and a lock-ring brake device 4343. The shock absorber 42 first controls the elastic rear frame 411 to open a specific angle (set angle θ), decomposing the speed. Part of the kinetic energy is absorbed by the elastic rear frame 411. During this process, the vehicle is less impacted, but the vehicle speed can be reduced according to a specific ratio (the sine value sinθ of the set angle θ). After idling for 0.5ms, the elastic belt 437 engages with the universal joint transmission device 2. The residual torque of the universal joint transmission device 2 causes the elastic belt 437 to tighten rapidly, converting the kinetic energy into potential energy. During this process, the vehicle is subjected to a large impact and can quickly reduce the vehicle speed to zero.
[0091] In some embodiments, as Figures 30 to 33 As shown, the vibration damping system 5 includes a vibration damping outer disk 51, a vibration damping inner disk 52, a vibration damping arm 53, a connecting head 54 and a vibration damping suspension 55. The vibration damping outer disk 51 is provided with an outer disk holder 511, an outer disk wiper 512, an elastic element 513 and a positioning ring 514. One end of the vibration damping outer disk 51 is fixed to the center of the spoke through the outer disk holder 511, and the other end of the vibration damping outer disk 51 is connected to one side of the vibration damping inner disk 52 through the positioning ring 514 and the outer disk wiper 512. The pressing head 521 of the vibration damping inner disk 52 is stuck on the positioning ring 514, pressing the vibration damping elastic elements 513 on both sides to obtain the damping The damping mechanism 521 is a structure that generates a force to damp vibrations. The inner disk wiper 522 and the outer disk wiper 512 squeeze each other to generate friction, thereby reducing relative slip. The other side of the damping inner disk 52 is connected to the damping arm 53, which is connected to the damping suspension 55 via a connector 54. The damping suspension 55 includes a piston push rod 551, a fluid reservoir rod 552, and a damping elastic element 533. The damping suspension 55 is connected to the cabin body 11 to provide a vertical damping effect. Suspension valves 1111 are provided on both sides of the cabin body 11, and the suspension valves 1111 are connected to the damping suspension 55. When turning, the relative position of the cabin can be changed by changing the inclination angle of the damping suspension 55 to change the center of gravity of the vehicle, thereby lowering the center of gravity, increasing cornering speed, and reducing steering centrifugal force.
