Detailed Description
Referring to fig. 1, fig. 2 and fig. 3, an embodiment of the present application provides a kinetic energy recovery and release device 100, where the kinetic energy recovery and release device 100 includes:
a running assembly 10, wherein the running assembly 10 is provided with a wheel shaft 11, and the wheel shaft 11 is used for outputting running torque;
a brake assembly 20 connected to the traveling assembly 10, the brake assembly 20 having a first braking state, wherein the brake assembly 20 applies a static friction brake to the wheel axle 11 and receives a first torque from the wheel axle 11 when in the first braking state;
a transmission assembly 30 connected to the brake assembly 20 for receiving the torque of the brake assembly 20 and converting the torque into a second torque, wherein the second torque is opposite to the first torque;
the energy storage assembly 40 comprises a rotating shaft fitting part 41 and an energy storage torsion spring 42 connected with the rotating shaft fitting part 41, and the rotating shaft fitting part 41 has a holding state and a disconnecting state. When the rotating shaft fitting part 41 is in the off state, the rotating shaft fitting part is disengaged from the wheel shaft 11, and receives the reverse torque of the transmission assembly 30, so that the reverse torque is transmitted to the energy storage torsion spring 42, and the energy storage torsion spring 42 converts the reverse torque into elastic potential energy for storage. When the rotating shaft fitting part 41 is in the clasping state, the rotating shaft fitting part clasps the wheel shaft 11, receives the elastic potential energy of the energy storage torsion spring 42, converts the elastic potential energy into a third torque, and transmits the third torque to the wheel shaft 11, wherein the third torque is opposite to the second torque in direction.
It can be understood that the kinetic energy recovery and release device 100 is applied to a vehicle, and during the braking process of the vehicle, the kinetic energy recovery and release device 100 is used for converting the braking kinetic energy into elastic potential energy for recovery, and when the kinetic energy needs to be reused, the elastic potential energy is converted into running torque, so that the energy consumption of the vehicle is reduced.
The brake assembly 20 can receive a first torque of the wheel axle 11 in a first braking state, the transmission assembly 30 converts the first torque into a second torque and transmits the second torque to the energy storage torsion spring 42 of the energy storage assembly 40, the energy storage torsion spring 42 stores kinetic energy of the second torque and transmits the stored elastic potential energy to the wheel axle 11 through the rotating shaft fitting piece 41 in a state that the rotating shaft fitting piece 41 is tightly held with the wheel axle 11, so that braking kinetic energy can be effectively recovered and stored, and the wheel axle 11 can be effectively driven to rotate in a releasing manner.
In the present embodiment, the wheel shaft 11 can output a running torque by the driving action of the engine. The running torque of the wheel shaft 11 can act on the wheels of the vehicle, so as to drive the vehicle to move forward or backward. The end of the wheel shaft 11 outputs a running torque to the wheels of the vehicle. The wheel shaft 11 is engaged with the rotating shaft fitting 41 of the energy storage assembly 40 at the end far away from the end to receive the kinetic energy released by the energy storage assembly 40. The wheel shaft 11 is fitted with the brake assembly 20 adjacent to the end thereof to facilitate braking of the wheel shaft 11 by the brake assembly 20. Of course, in other embodiments, the rotating shaft mating part 41 of the energy storage assembly 40 may also be indirectly mated with the wheel shaft 11, that is, the rotating shaft mating part 41 may transmit the stored elastic potential energy to the wheel shaft 11 through a transmission member.
In the present embodiment, the brake assembly 20 may directly brake the wheel shaft 11, may brake a wheel coupled to a hub of the wheel shaft 11, or may brake the wheel shaft 11 via a transmission. When the brake assembly 20 is in the first braking state, a damping force is provided to the wheel shaft 11, so that the rotation speed of the wheel shaft 11 is reduced, in the process of reducing the rotation speed of the wheel shaft 11, the wheel shaft 11 does not stop rotating immediately, the wheel shaft 11 still rotates in a reduced speed state in the original steering direction, so that the brake assembly 20 can obtain a first torque in the same direction as the driving torque, that is, the brake assembly 20 recovers the braking kinetic energy of the wheel shaft 11 in a manner of obtaining the first torque, and the braking kinetic energy of the brake assembly 20 does not form waste of friction heat energy.
In this embodiment, the transmission assembly 30 is connected to the brake assembly 20 and the rotating shaft fitting 41. The transmission assembly 30 may be driven by a gear set, a transmission belt, or a worm. The transmission assembly 30 converts the first torque into a second torque, so that when the energy storage assembly 40 releases the kinetic energy, the wheel axle 11 can obtain a third torque opposite to the second torque, that is, the third torque has the same direction as the first torque, that is, when the wheel axle 11 reuses the braking kinetic energy, the vehicle can be driven to keep the original driving direction for driving.
In this embodiment, when the rotating shaft fitting 41 is in the disconnected state and the brake assembly 20 is in the first braking state, the rotating shaft fitting 41 and the wheel shaft 11 are separated from each other, the rotating direction of the rotating shaft fitting 41 is opposite to the rotating direction of the wheel shaft 11, and the rotating shaft fitting 41 receives the second torque and does not interfere with the rotation of the wheel shaft 11, so as to prevent the wheel shaft 11 from being locked by the opposite force of the rotating shaft fitting 41. The energy storage torsion spring 42 generates elastic deformation under the action of the second torque of the rotating shaft mating piece 41, so that the energy storage torsion spring 42 generates elastic compression, that is, the second torque of the rotating shaft mating piece 41 is converted into elastic potential energy to be stored.
When the wheel axle 11 needs to use the braking kinetic energy, the rotating shaft fitting part 41 is switched to the holding state, and the brake assembly 20 is in the non-first braking state, the brake assembly 20 is independent from the wheel axle 11, and the brake assembly 20 does not exert a braking action on the wheel axle 11. In this state, the rotating shaft fitting part 41 and the wheel shaft 11 are fastened to each other, and the energy storage torsion spring 42 releases the elastic potential energy stored by the compression deformation to the rotating shaft fitting part 41, so that the rotating shaft fitting part 41 obtains a third torque opposite to the second torque direction, and the wheel shaft 11 obtains the third torque. Since the third torque is in the same direction as the first torque, the wheel axle 11 can drive the vehicle to keep the driving direction during braking.
Further, the brake assembly 20 has a second braking state, and when the brake assembly 20 is in the second braking state, the brake assembly applies dynamic friction brake to the wheel shaft 11, stops receiving the first torque of the wheel shaft 11, and limits the energy storage torsion spring 42 of the energy storage assembly 40 to release elastic potential energy through the transmission assembly 30.
In this embodiment, the energy storage torsion spring 42 is an elastic member. The energy storage torsion spring 42 has an energy storage saturation state, that is, the energy storage torsion spring 42 is elastically compressed and has a limit deformation state. When the elastic deformation of the energy storage torsion spring 42 exceeds the limit deformation state, the energy storage torsion spring 42 will break, resulting in that energy can not be stored any more. Therefore, when the energy storage torsion spring 42 is in the extreme deformation state, the elastic potential energy stored in the energy storage torsion spring 42 is saturated and cannot absorb energy any more. In order to ensure the safety of the energy storage torsion spring 42, so that the energy storage assembly 40 can recover and release the circulating kinetic energy, when the energy storage torsion spring 42 is in the energy storage saturation state, the brake assembly 20 is switched to the second braking state. When the brake assembly 20 is in the second braking state, the brake assembly 20 and the wheel axle 11 are converted from static friction to dynamic friction, i.e., the damping member of the brake assembly 20 stops rotating, so that the energy storage assembly 40 no longer recovers the braking kinetic energy. When the brake assembly 20 is in the second braking state, the brake assembly 20 limits the deformation of the energy storage torsion spring 42 through the transmission assembly 30, so that the energy storage torsion spring 42 neither stores kinetic energy nor releases elastic potential energy, that is, the elastic potential energy of the energy storage torsion spring 42 can be released to the wheel axle 11 when needed.
In this embodiment, whether the energy storage torsion spring 42 is in the energy storage saturation state or not may be detected by a pressure sensor, that is, the energy storage assembly 40 may include a pressure sensor connected to the energy storage torsion spring 42, and the pressure sensor may monitor the elastic force of the energy storage torsion spring 42. When the pressure sensor detects that the elastic force of the energy storage torsion spring 42 reaches a first preset threshold value, the energy storage torsion spring 42 is considered to be in an energy storage saturation state, and the energy storage torsion spring 42 can not continuously absorb the kinetic energy, so that the brake assembly 20 can be controlled to be in a second braking state. When the pressure sensor detects that the elastic force of the energy storage torsion spring 42 reaches a second preset threshold value, the energy storage torsion spring 42 is considered to be in a free extension state, the energy storage torsion spring 42 has no elastic potential energy to store, the energy storage torsion spring 42 can absorb the braking kinetic energy, and the brake assembly 20 can be controlled to be in a first braking state when the vehicle brakes. Of course, in other embodiments, the rotation angle of the wheel axle 11 may be monitored by an angle sensor to monitor whether the energy storage torsion spring 42 reaches the energy storage saturation state, or a displacement sensor may detect the elastic deformation displacement of the energy storage torsion spring 42 to monitor whether the energy storage torsion spring 42 reaches the energy storage saturation state.
In this embodiment, the brake assembly 20 further has a non-braking state, and when the brake assembly 20 is in the non-braking state, the brake assembly 20 is independent from the wheel axle 11, and the brake assembly 20 may be in a static loading state or a moving state. When the brake assembly 20 is in a non-braking state and the rotating shaft fitting part 41 is in a clasping state, the elastic potential energy of the energy storage torsion spring 42 is transmitted to the wheel rotating shaft and the brake assembly 20 through the rotating shaft fitting part 41, and since the brake assembly 20 does not provide a damping force to the wheel shaft 11, that is, the brake assembly 20 idles, the wheel shaft 11 drives the vehicle to run under the driving of the elastic potential energy. When the brake assembly 20 is in the non-braking state and the rotating shaft fitting member 41 is in the disconnected state, the brake assembly 20 limits the rotation of the rotating shaft fitting member 41 through the transmission assembly 30, so as to limit the deformation of the energy storage torsion spring 42, that is, the energy storage torsion spring 42 is limited to release the elastic potential energy, so that the elastic potential energy of the energy storage torsion spring 42 is released to the wheel axle 11 when needed.
Further, the running assembly 10 is provided with a wheel 12 for coupling the wheel shaft 11 with a hub and a bracket 13 for rotatably connecting the wheel shaft 11. The brake assembly 20 is provided with a brake pad 21 slidably and rotatably coupled to the bracket 13.

In this embodiment, the wheel 12 is coupled to the axle hub of the wheel axle 11 such that the torque of the wheel axle 11 can drive the wheel 12 to rotate, and the wheel 12 can drive the vehicle to travel. The bracket 13 may provide a bearing force to the wheel axle 11. The bracket 13 can also provide the bearing capacity of the brake assembly 20, the transmission assembly 30 and the energy storage assembly 40, so that the kinetic energy recovery and release device 100 is structurally stable. The bracket 13 may be a chassis of a vehicle, or may be a steel skeleton disposed on the chassis of the vehicle.
Specifically, the brake pad 21 can slide relative to the bracket 13 along a direction parallel to the wheel axis 11, and the brake pad 21 can abut against the wheel 12 or be separated from the wheel 12. The brake block 21 is also rotatable about the wheel axle 11, and the rotational axis of the brake block 21 is arranged coaxially with the wheel axle 11, i.e. the wheel axle 11 passes through the brake block 21. The brake pad 21 provides a rotational damping force to the wheel 12, and when the brake pad 21 rotates with the wheel 12, the brake pad 21 and the wheel 12 are in static friction braking, that is, the brake assembly 20 brakes the wheel shaft 11 in static friction braking, and the brake assembly 20 is in a first braking state. The brake pad 21 provides a rotational damping force to the wheel 12 and is fixed relative to the bracket 13, and when the brake pad 21 rotates relative to the wheel 12, the brake pad 21 and the wheel 12 perform dynamic friction braking, and the brake assembly 20 is in a second braking state. Brake block 21 slide to with the position of wheel 12 separation, brake block 21 also can be relative support 13 is fixed, brake block 21 also can pass through transmission assembly 30 restriction pivot fitting piece 41 is relative support 13 is fixed, the restriction energy storage torsional spring 42 deformation forbids energy storage torsional spring 42 release elastic potential energy extremely pivot fitting piece 41. The brake pad 21 slides to a position separated from the wheel 12, and the brake pad 21 can also rotate relative to the bracket 13 and rotate in the opposite direction relative to the wheel 12, that is, the energy storage torsion spring 42 releases the elastic potential energy to the rotating shaft of the wheel 12 and releases the elastic potential energy through the transmission assembly 30, so that the brake pad 21 rotates in the opposite direction to the wheel shaft 11.
Further, the energy storage assembly 40 further includes an energy storage frame 43 fixed to the support 13, one end of the energy storage torsion spring 42 is fixed to the energy storage frame 43, and the other end is fixedly connected to the rotating shaft fitting 41.

One end of the energy storage torsion spring 42 is fixed on the inner wall of the accommodating cavity 431, and the other end is fixed on the rotating shaft fitting piece 41. When the rotating shaft fitting piece 41 is acted by the transmission assembly 30 to rotate, the rotating shaft fitting piece 41 drives the energy storage torsion spring 42 to elastically compress and deform, and then the kinetic energy storage is realized. Energy storage frame 43 is the box body, energy storage frame 43 can be right energy storage torsional spring 42 protects, prevents that energy storage torsional spring 42 from being drawn into impurity, and influences energy storage torsional spring 42 elastic deformation, and then influences the storage kinetic energy.
