The present invention further provides a vehicle, which includes a vehicle body 80 and a power system 100, and the specific structure of the power system 100 refers to the above embodiments, and since the vehicle adopts all the technical solutions of all the above embodiments, the vehicle at least has all the beneficial effects brought by the technical solutions of the above embodiments, and details are not repeated herein.

In the present embodiment, the vehicle body 80 is provided with an axle 81, and the drive wheel 10 is connected to an end of the axle 81. It is understood that the vehicle may include one or more powertrain systems 100, and is not limited thereto.

It is understood that the vehicle may be an automobile, a motorcycle, a tricycle, a truck, a bus, etc., and is not limited thereto.

According to the power system 100 of the vehicle, the bladder 20 is arranged in the tire cavity 11 of the driving wheel 10, the bladder 20 is provided with the bladder cavity 21 and the inlet 22 and the outlet 23 which are communicated with the bladder cavity 21, the inlet 22 is communicated with the external atmosphere, the outlet 23 is communicated with the storage structure 30, and then gas is output through the output port of the storage structure 30, so that the gas can do work. There are many ways of gas work, and the electric power of the whole vehicle can be supplemented, and the power of the vehicle can also be supplemented. During the running of the vehicle, the driving wheel 10 runs, the expansion and compression of the tire cavity 11 are realized by means of the gravity of the vehicle and the elastic force of the driving wheel 10, and when the tire cavity 11 is compressed, the bladder 20 is pressed, so that the gas in the bladder 20 is discharged to the storage structure 30. When utricule 20 is gaseous not enough, the outside air enters into bag chamber 21 by import 22 again to realize gaseous replenishment, so circulation is reciprocal, can guarantee the gaseous sufficient in the storage structure 30 all the time at the in-process that the vehicle was marchd, and then makes the power and/or the electric power of vehicle can both obtain guaranteeing, has both solved the environmental pollution problem of traditional fuel vehicle, has solved the short problem of current electric motor car continuation of the journey mileage again.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
