It will be appreciated that the pneumatic conversion device 40 may store a target liquid therein, when the power mechanism 10 brakes, the rotating portion of the power mechanism 10 will not stop immediately, and the power mechanism 10 can drive the pneumatic conversion device 40 to transmit excessive power to the pneumatic conversion device 40 in the gradual deceleration process of the vehicle, and the pneumatic conversion device 40 can convert kinetic energy into internal energy, so that the target liquid in the pneumatic conversion device 40 is gasified and converted into a target gas.

As shown in fig. 1, in some embodiments, the vehicle energy recovery system further comprises: a transmission mechanism 30.
The transmission mechanism 30 is in power coupling connection with the pneumatic conversion mechanism, and the transmission mechanism 30 is in power coupling connection with the power mechanism 10 when the power mechanism 10 brakes.
It is understood that, during braking of the power mechanism 10, the pneumatic conversion mechanism may be coupled to the power mechanism 10 by the transmission mechanism 30, and the transmission mechanism 30 may be a belt transmission, a chain transmission, a gear transmission or a link transmission, which is not limited herein, and a person skilled in the art may select the form of the transmission mechanism 30 according to the requirement.
As shown in fig. 1, in some embodiments, the vehicle energy recovery system further comprises: a braking device 20.
The transmission mechanism 30 is mounted on the brake device 20, and the pneumatic conversion device 40 is configured to be coupled with the power mechanism 10 when the brake device 20 brakes the power mechanism 10.
It will be appreciated that the braking device 20 is used to brake the power mechanism 10 of the vehicle, and when a user wishes to slow the vehicle, the braking device 20 may be triggered by a mechanical structure or an electrical control device, and the braking device 20 may interfere with the movement of the power mechanism 10, thereby slowing the power mechanism 10.
The transmission mechanism 30 can be installed on the braking device 20, when the braking device 20 is triggered, the braking device 20 can brake the power structure, at this time, the transmission mechanism 30 and the power mechanism 10 are in power coupling connection, so that the transmission mechanism 30 can collect redundant kinetic energy of the power mechanism 10 while interfering with the motion of the power structure, and transmit the part of kinetic energy to the pneumatic conversion device 40 to drive the pneumatic conversion device 40, thereby enabling the pneumatic conversion device 40 to convert target liquid into target gas under the driving of the kinetic energy.
The connection between the pneumatic conversion device 40 and the power mechanism 10 can be more stable and reliable through the transmission mechanism 30, and the speed conversion efficiency is higher.
The process of braking by the braking device 20 may also be referred to as braking, and refers to an action of stopping or slowing down a locomotive, vehicle, and other transportation or machinery in operation. The general principle of braking is to fix a wheel or disc on the high-speed shaft of the machine, mount a brake shoe, belt or disc adapted to it on the machine base, and make it generate braking moment under the action of external force. The brake means is also known as a mechanical brake means 20, also known as a retarder, which can slow down the vehicle. Briefly, the method comprises the following steps: the automobile brake pedal is arranged below the steering wheel, and the brake pedal is stepped on, so that the brake lever is pressed in a linkage way and is transmitted to a brake pad on the brake drum to clamp the brake wheel disc, and the automobile is decelerated or stopped. The manual brake of the automobile is arranged beside a gear and connected with a brake lever. There are also common bicycle brakes which are decelerated by means of rod brakes or disc brake brakes or the like fixed to the frame.
The brake device 20 on the present vehicle may include drum brakes and disc brakes.
The drum brake mainly comprises two semicircular brake pads arranged in a wheel hub, and the brake pads are pushed by utilizing the lever principle to enable the brake pads to be in contact with the inner surface of the wheel drum so as to generate friction. The drum brake is operated by using a stationary brake pad in a brake drum to rub the brake drum rotating with the wheel to generate a friction force to reduce the rotation speed of the wheel. When the brake pedal is depressed, the force exerted by the foot will cause the piston in the master cylinder to push the brake oil forward and create pressure in the oil path. The pressure is transmitted to the brake cylinder piston of each wheel through the brake oil, and the piston of the brake cylinder pushes the brake pad outwards, so that the brake pad rubs with the inner surface of the brake drum and enough friction force is generated to reduce the rotating speed of the wheel, thereby achieving the purpose of braking.
The drum brake has an automatic tightening function, so that the brake system can use lower oil pressure or use a brake drum with a diameter much smaller than that of a brake disc. The hand brake mechanism is easy to install, and some rear wheel device disc brake vehicle types can install the hand brake mechanism of the drum brake at the center of the brake disc. The parts are simpler to process and compose and the manufacturing cost is lower.
Meanwhile, the diameter of the brake drum of the drum brake is increased after being heated, so that the stroke of stepping on the brake pedal is increased, and the situation that the brake reaction is not as expected easily occurs. Therefore, when a vehicle adopting drum brake is driven, the heat fading phenomenon of the brake pad caused by high temperature due to continuous brake is avoided as much as possible. The braking system has slower response, the stepping force of the brake is not easy to control, and the high-frequency braking action is not facilitated. The structure is complex, the number of parts is large, and the brake clearance needs to be adjusted, so that the maintenance is not easy. Since the performance and the running speed of a vehicle are increasing, disc brake has become the mainstream of the current brake system in order to increase the stability of braking when the vehicle is running at a high speed. Because the brake disc of the disc brake is exposed in the air, the disc brake has excellent heat dissipation, and when the vehicle is braked rapidly in a high-speed state or braked for a plurality of times in a short time, the braking performance is not easy to decline, and the vehicle can obtain a better braking effect so as to improve the safety of the vehicle.
And because the reaction of the disc brake is quick and the disc brake has the capability of performing high-frequency braking action, a plurality of vehicle models adopt the disc brake to be matched with an ABS system, a VSC system, a TCS system and other systems so as to meet the requirement that the systems need to do work quickly.
The two brake pads are controlled by the brake caliper to clamp the brake disc on the wheel. Friction is generated between the brake pads when they clamp the disc. When an automobile runs on a wet or frozen low-friction road surface, if excessive braking occurs, wheels can be locked by a braking device and lose the grabbing force, so that the automobile loses the capability of controlling the direction. In order to enable the vehicle to effectively control the direction of travel on such dangerous roadways, ABS "antilock braking systems" have been developed. The ABS anti-lock braking system with stronger performance can also enable the TCS-Traction Control System tracking control system and the VSC-Vehicle Stability Control vehicle stability control system (equivalent to ESP) to control the tracking performance of the vehicle when running and the stability performance of the vehicle when over-bending when the vehicle is running when the running is excessive.
Drum brakes have been applied to automobiles for nearly a century, but drum brakes are still deployed today on many vehicle types (for use in rear wheels) due to their reliability and strong braking forces. The drum brake uses hydraulic pressure to push the brake pad installed in the brake drum outwards, so that the brake pad rubs with the inner surface of the brake drum rotating along with the wheel, and the braking effect is generated.
The inner surface of the brake drum of the drum brake is the position where the brake device generates the brake moment. The diameter of the brake drum of the drum brake assembly can be much smaller than the disc brake rotor of the disc brake, with the same braking torque. Therefore, large-sized vehicles for load use can only install drum brakes in a limited space of a rim in order to obtain strong braking force.
The disc brake clamps the brake disc rotating along with the tyre by using a static brake disc to generate friction force, so that the rotation speed of the wheel is low. When the brake pedal is depressed, the piston in the brake master cylinder is pushed, and pressure is built up in the brake oil path. The pressure is transmitted to the piston of the brake cylinder on the brake caliper through the brake oil, and after the piston of the brake cylinder is subjected to the pressure, the piston can outwards move and push the brake pad to clamp the brake disc, so that the brake pad and the brake disc are rubbed to reduce the rotation speed of wheels, and the automobile is well decelerated or stopped.
The heat dissipation of the disc brake is better than that of a drum brake, and the brake failure phenomenon caused by brake decay can not be caused when the brake is continuously stepped on. The change in size of the brake disc after heating does not increase the travel of the pedal. The response of the disc brake system is quick, and the disc brake system can perform high-frequency braking action, so that the disc brake system meets the requirements of an ABS system. The disc brake has no automatic braking action of the drum brake, so that the braking forces of the left and right wheels are relatively average. Because the drainage property of the brake disc is better, the bad situation of braking caused by water or sediment can be reduced. Compared with drum brakes, the disc brake has simple structure and easy maintenance.
The disc brake has lower braking force than the drum brake because of no automatic braking action of the drum brake. The friction area between the brake pad and the brake disc of the disc brake is smaller than that of a drum brake, so that the braking force is smaller. To improve the above-mentioned disadvantage of disc brake, a larger stepping force or oil pressure is required. It is necessary to use a larger diameter disc or to increase the oil pressure of the brake system to increase the braking force. The hand brake device is not easy to install, and a group of drum brake hand brake mechanisms are additionally arranged for the vehicle type with disc brake on the rear wheels. The wear of the brake pads is large, and the replacement frequency may be high.
It should be noted that the present invention is not limited to the type of brake device 20, and both drum brakes and disc brakes can be used to mount the brake device 20 and the transmission together to collect kinetic energy during braking.
In some embodiments, the transmission 30 includes: friction wheel and belt.
The friction wheel is attached to the braking device 20, and is brought into contact with the rotating portion of the power mechanism 10 when the power mechanism 10 brakes.
It will be appreciated that the friction wheel may be integrated on the brake device 20, and when the brake device 20 is triggered, the brake device 20 may interfere with the movement of the power mechanism 10, for example, may contact with the rotating portion of the power mechanism 10, and provide resistance to the power mechanism 10 through friction, and when the brake device 20 contacts with the rotating portion of the power mechanism 10, the friction wheel may be driven by the brake device 20 to contact with the rotating portion of the power mechanism 10 in a pressing manner, so as to transmit the power of the power mechanism 10.
The belt is in power coupling connection with the friction wheel and the belt is in power coupling connection with the power input end of the pneumatic conversion device 40.
It will be appreciated that the belt may be driven by the friction wheel, so as to transmit power to the pneumatic conversion device 40, the power input end of the pneumatic conversion device 40 may be a rotation shaft, and the belt may be used as a medium, so that the rotation shaft and the friction wheel may be a synchronous belt transmission structure, thereby realizing stable power transmission.
The friction wheel material should meet the following requirements: the elastic modulus is larger, so that the elastic sliding and the power loss are reduced; the friction coefficient is larger, the larger friction force can be provided, and the transmission capacity is improved; the contact fatigue strength is high; the wear resistance is good, and the service life is prolonged; has small sensitivity to temperature and humidity.
The types of friction wheel transmission are different according to the relative positions of the axes of the two friction wheels, and the friction wheels can be divided into two types of parallel two shafts and crossed two shafts.
The two shafts are parallel with a cylindrical friction wheel and a groove-shaped friction wheel. The cylindrical friction wheel has simple structure, convenient manufacture and large pressing force, and is divided into an external connection type and an internal connection type. Used for low-power transmission, such as an instrument adjusting device and the like. The groove-shaped friction wheel is provided with grooves with angles of 2 beta, and the side surfaces are contacted, so that the tangential friction force can be increased under the condition of the same pressing force, and the transmission power is improved. But is easy to generate heat and wear, has lower transmission efficiency and higher requirements on processing and installation. The device is suitable for machinery such as a winch driving device and the like.
The two shafts are intersected with a conical friction wheel and an end face friction wheel. The conical friction wheel is designed and installed to ensure that the relative positions of axes are correct, and conical tops are coincident and are divided into two types, namely vertical and non-vertical. Is commonly used for high-power friction presses. The end face friction wheel has simple structure, convenient manufacture and large pressing force; the heating and abrasion are easy, and the efficiency is low; has high requirements for processing and installation.
