Background

At present, for a traditional automobile brake system, when a driver encounters an emergency, the driver can rapidly brake the automobile by suddenly stepping on the brake, so that accidents of the automobile are avoided. In the process of normally driving the automobile by a driver, the reaction time of the driver in normal hard braking is very short, once an emergency occurs, the reaction time of the driver in hard braking is usually more than 1 second, even the reaction time of the driver in hard braking in a certain panic state is about 2 seconds; in the 1 to 2 second emergency brake application response time, the vehicle is driven a relatively long distance at high speed, and the possibility of the vehicle touching an accident is increased. In order to shorten the sudden braking time of a driver in an emergency compared with the sudden braking time of a traditional automobile, a quick braking system needs to be designed so as to compensate the reaction time of the driver. The invention designs a brake system used on an automobile to solve the problems.

The L-shaped plate is designed to support the driving shaft, so that the supporting shaft is prevented from being bent under the action of the long-time gravity of the flywheel.

The design of the Z-shaped plate is that when the sliding block slides, the sliding block can drive the telescopic inner shaft to slide in the outer sleeve shaft through a corresponding bearing in the Z-shaped plate, and the design of the Z-shaped plate can ensure that the positions of the telescopic inner shaft and the third rotating shaft are kept relatively static, so that the bevel teeth in the bevel tooth combination are always in a meshing state and cannot be separated.

Characteristics of non-Newtonian fluids: the viscosity of the non-Newtonian fluid can change due to the pressure or speed, the viscosity can increase when the pressure is higher, and the non-Newtonian fluid can even become a temporary solid, and the viscosity is very soft when the pressure is lower.

When the third gear is set to rotate clockwise, the first rack moves downwards, and the design of the one-way clutch is as follows: since the one-way clutch has an overrunning action, when the third gear rotates in the clockwise direction, it can occur that the clockwise rotation speed of the third gear exceeds the clockwise rotation speed of the second gear.

The V-shaped plate is in extrusion contact with the third rotating shaft, and the friction wheel and the flywheel are matched with each other: firstly, when the brake bar moves downwards slowly, the brake bar drives the V-shaped plate to move downwards slowly through the shell B, the piston B and the rectangular bar, and the V-shaped plate moves downwards slowly due to the fact that the second spring is in a compressed state, and the third rotating shaft, the sliding block and the second guide block are difficult to move towards the direction of the flywheel due to the fact that the V-shaped plate moves downwards slowly; in the process that the V-shaped plate moves downwards slowly, the extrusion force of the V-shaped plate to the third rotating shaft is small, so that the thrust transmitted to the piston B by the third rotating shaft through the V-shaped plate and the rectangular strip is small, and the pressure of the piston B to the non-Newtonian fluid is small; according to the characteristics of the non-Newtonian fluid, the V-shaped plate pushes the piston B to move towards the direction of the brake strip through the rectangular strip, so that the brake strip is ensured to drive the V-shaped plate to slowly move downwards through the shell B, the piston B and the rectangular strip; in the process that the brake bar moves downwards slowly, the third rotating shaft basically cannot move towards the direction of the flywheel, so that the friction wheel cannot be pressed to contact the flywheel; secondly, when the brake bar moves downwards rapidly, the brake bar drives the V-shaped plate to move downwards rapidly through the shell B, the piston B and the rectangular bar, and in the process of moving downwards rapidly, the extrusion force of the V-shaped plate to the third rotating shaft is large, so that the thrust force transmitted to the piston B by the third rotating shaft through the V-shaped plate and the rectangular bar is large, and the pressure of the piston B to the non-Newtonian fluid is large; according to the characteristics of the non-Newtonian fluid, the V-shaped plate is difficult to push the piston B to move towards the direction of the brake strip through the rectangular strip; because the extrusion force of the brake strip moving downwards rapidly on the third rotating shaft is larger, the counter thrust of the second spring is overcome, and then the V-shaped plate moves downwards rapidly to push the third rotating shaft to move towards the direction of the flywheel in an extrusion mode, so that the third rotating shaft, the sliding block and the second guide block move towards the direction of the flywheel; thereby ensuring that the brake strip drives the V-shaped plate to rapidly move downwards through the shell B, the piston B and the rectangular strip; in the process that the brake bar moves downwards rapidly, the third rotating shaft moves towards the direction of the flywheel, so that the friction wheel can be pressed to contact the flywheel.

When the third gear 19 is set to rotate clockwise, the first rack 7 moves downward, and the one-way clutch 20 is designed such that: since the one-way clutch 20 has an overrunning action, such that when the third gear 19 rotates in a clockwise direction, it can occur that the clockwise rotational speed of the third gear 19 exceeds the clockwise rotational speed of the second gear 18.

The V-shaped plate 42 is in pressing contact with the third rotating shaft 34, and the friction wheel 35 and the flywheel 38 are matched to function as: firstly, when the brake bar 40 moves downwards slowly, the brake bar 40 drives the V-shaped plate 42 to move downwards slowly through the B shell 48, the B piston 49 and the rectangular bar 43, and since the second spring 26 is in a compressed state, the V-shaped plate 42 moves downwards slowly, so that the third rotating shaft 34, the sliding block 24 and the second guide block 25 are difficult to move towards the flywheel 38; in the process that the V-shaped plate 42 moves downwards slowly, the extrusion force of the V-shaped plate 42 on the third rotating shaft 34 is small, so that the thrust force transmitted to the piston B49 by the third rotating shaft 34 through the V-shaped plate 42 and the rectangular strip 43 is small, and the pressure of the piston B49 on the non-Newtonian fluid is small; according to the characteristics of the non-Newtonian fluid, the V-shaped plate 42 pushes the B piston 49 to move towards the brake strip 40 through the rectangular strip 43, so that the brake strip 40 is ensured to drive the V-shaped plate 42 to slowly move downwards through the shell B48, the B piston 49 and the rectangular strip 43; during the slow downward movement of the brake bar 40, the third rotating shaft 34 does not move substantially toward the flywheel 38, so that the friction wheel 35 does not press against the flywheel 38. Secondly, when the brake strip 40 moves downwards rapidly, the brake strip 40 drives the V-shaped plate 42 to move downwards rapidly through the shell B48, the piston B49 and the rectangular strip 43, and in the process that the V-shaped plate 42 moves downwards rapidly, the extrusion force of the V-shaped plate 42 to the third rotating shaft 34 is large, the thrust force transmitted to the piston B49 by the third rotating shaft 34 through the V-shaped plate 42 and the rectangular strip 43 is large, and the pressure of the piston B49 on the non-Newtonian fluid is large; according to the characteristics of the non-Newtonian fluid, the V-shaped plate 42 is difficult to push the B piston 49 to move towards the direction of the brake bar 40 through the rectangular bar 43; because the brake strip 40 moves downwards rapidly to have a larger extrusion force on the third rotating shaft 34, the reverse thrust of the second spring 26 is overcome, and then the V-shaped plate 42 moves rapidly downwards to push the third rotating shaft 34 to move towards the flywheel 38 in an extrusion manner, so that the third rotating shaft 34, the sliding block 24 and the second guide block 25 move towards the flywheel 38; thereby ensuring that the brake bar 40 drives the V-shaped plate 42 to rapidly move downwards through the shell B48, the piston B49 and the rectangular bar 43; during the downward rush movement of the brake bar 40, the third shaft 34 will move toward the flywheel 38 such that the friction wheel 35 will press against the flywheel 38.

The reduction motor 36 of the present invention is electrically connected to a battery in the automobile through a wire.

In the invention, the position of the pedal base 4 is positioned on a bottom plate at the right lower part of a main seat in a cab, and a groove is formed on the bottom plate; preferably, the step base is mounted in the recess and the step base is flush with the base plate.

The specific working process of the invention is as follows:

when the third gear 19 is set to rotate clockwise as shown in fig. 6, the first rack 7 moves downward, and the one-way clutch 20 is designed such that: since the one-way clutch 20 has an overrunning action, such that when the third gear 19 rotates in a clockwise direction, it can occur that the clockwise rotational speed of the third gear 19 exceeds the clockwise rotational speed of the second gear 18.

When the brake pedal 1 is not pressed down, the telescopic rod 2 and the telescopic rod spring 3 are not compressed; the third rotating shaft 34 is not extruded by the V-shaped plate 42, the third rotating shaft 34 and the V-shaped plate 42 are in a contact state, and the extrusion force of the V-shaped plate 42 to the third rotating shaft 34 is substantially zero; the second spring 26 is in a compressed state, and a gap exists between the friction wheel 35 and the flywheel 38; as shown in fig. 5, the brake connecting plate 6 is not pulled by external force, and the first spring 9 is not stretched; as shown in fig. 13, the B piston 49 abuts against a side cavity surface of the B accommodating cavity 51 away from the brake strip 40; the piston A45 is not extruded by Newtonian fluid, the piston A45 is close to the inlet and the outlet of the square tube 47 communicated with the shell A44, and the spring A46 is slightly compressed; the end of the second rack 41 far away from the pedal base 4 is meshed with the first gear 17, the first gear 17 is meshed with the second gear 18, the end of the first rack 7 far away from the pedal base 4 is meshed with the third gear 19, and the conical teeth 55 on the third gear 19 are meshed with the conical teeth 55 on the fourth gear 31.

When the automobile is started, the reducing motor 36 is started by a control system in the automobile, the reducing motor 36 drives the flywheel 38 to rotate through the driving shaft 37, after the flywheel 38 rotates for a certain time, the rotating speed of the flywheel 38 reaches the maximum, and at the moment, the rotating energy of the flywheel 38 reaches the maximum.

When a driver slowly steps on the brake pedal 1, the telescopic rod 2 and the telescopic rod spring 3 are compressed, and the brake pedal 1 drives the brake strip 40 to slowly move downwards; the brake bar 40 drives the first gear 17 to slowly rotate anticlockwise through the second gear bar 41, the first gear 17 drives the second gear 18 to slowly rotate clockwise, as shown in fig. 6, the second gear 18 drives the third gear 19 to slowly rotate clockwise through the second rotating shaft 16 and the one-way clutch 20, the third gear 19 drives the brake connecting plate 6 to slowly move downwards through the first rack 7, the first guide block 8 slowly moves along with the brake connecting plate 6, and the first spring 9 is stretched; the downward movement of the brake link plate 6 causes the brake modules at the vehicle tires to perform a braking action. The brake bar 40 drives the V-shaped plate 42 to slowly move downwards through the B shell 48, the B piston 49 and the rectangular bar 43, and since the second spring 26 is in a compressed state, the V-shaped plate 42 slowly moves downwards, so that the third rotating shaft 34, the sliding block 24 and the second guide block 25 are difficult to move towards the flywheel 38; in the process that the V-shaped plate 42 moves downwards slowly, the extrusion force of the V-shaped plate 42 on the third rotating shaft 34 is small, so that the thrust force transmitted to the piston B49 by the third rotating shaft 34 through the V-shaped plate 42 and the rectangular strip 43 is small, and the pressure of the piston B49 on the non-Newtonian fluid is small; according to the characteristics of the non-Newtonian fluid, at the moment, the V-shaped plate 42 pushes the B piston 49 to move towards the brake pad 40 through the rectangular bar 43, the B piston 49 pushes the non-Newtonian fluid to flow from the B accommodating cavity 51 to the A accommodating cavity 50 through the square tube 47, the non-Newtonian fluid pushes the A piston 45 to move towards the A spring 46, and the A spring 46 is compressed; during the slow downward movement of the brake bar 40, the third rotating shaft 34 does not move substantially toward the flywheel 38, so that the friction wheel 35 does not press against the flywheel 38. In the whole process of slowly stepping on the brake pedal 1, under the condition that the downward moving distance of the brake bar 40 is equal to the downward moving distance of the brake connecting plate 6, the downward moving speed of the brake bar 40 is the same as the downward moving speed of the brake connecting plate 6. The effect of slowly depressing the brake pedal 1 of the present invention is equivalent to the effect of slowly depressing the brake pedal 1 of the conventional art.

When the driver does not step on the brake pedal 1 any more, under the reset action of the telescopic rod spring 3, the brake pedal 1 moves upwards, the brake pedal 1 drives the brake strip 40 to move upwards for reset, and in the process that the brake pedal 1 drives the brake strip 40 to move upwards for reset, the brake strip 40 drives the first gear 17 to rotate clockwise through the second gear 41, and the first gear 17 drives the second rotating shaft 16 to rotate anticlockwise through the second gear 18. Because the one-way clutch 20 also has a one-way function, that is, when the second rotating shaft 16 rotates clockwise, the second rotating shaft 16 can drive the third gear 19 to rotate clockwise via the one-way clutch 20, and when the second rotating shaft 16 rotates counterclockwise, the second rotating shaft 16 cannot drive the third gear 19 to rotate counterclockwise via the one-way clutch 20. Because the second rotating shaft 16 can not drive the third gear 19 to rotate counterclockwise through the one-way clutch 20, the third gear 19 can not drive the first rack 7 to move upward to reset, however, under the reset action of the first spring 9, the first guide block 8 drives the brake connecting plate 6 to move upward to reset, so that the third gear 19 rotates counterclockwise. When the brake strip 40 moves upwards to reset, the brake strip 40 drives the V-shaped plate 42 to move upwards through the shell B48, the piston B49 and the rectangular strip 43, under the reset action of the spring a 46, the spring a 46 slowly pushes the piston a 45 to move towards the direction away from the spring a 46, the piston a 45 pushes the non-newtonian fluid to flow from the accommodating cavity a 50 to the accommodating cavity B51 through the square tube 47, the non-newtonian fluid pushes the piston B49 to move towards the direction away from the brake strip 40 to reset, the piston B49 drives the V-shaped plate 42 to move towards the direction away from the brake strip 40 through the rectangular strip 43 to reset, and during the period, the corresponding plate surface of the V-shaped plate 42 is always in contact with the third rotating shaft 34.

When a driver rapidly steps on the brake pedal 1, the telescopic rod 2 and the telescopic rod spring 3 are compressed, and the brake pedal 1 drives the brake strip 40 to rapidly move downwards; the brake bar 40 drives the first gear 17 to rapidly rotate anticlockwise through the second gear 41, the first gear 17 drives the second gear 18 to rapidly rotate clockwise, the second gear 18 drives the third gear 19 to rapidly rotate clockwise through the second rotating shaft 16 and the one-way clutch 20, the third gear 19 drives the brake connecting plate 6 to slowly move downwards through the first rack 7, the first guide block 8 follows the brake connecting plate 6 to rapidly move, and the first spring 9 is stretched. When the brake strip 40 moves downwards rapidly, the brake strip 40 drives the V-shaped plate 42 to move downwards rapidly through the shell B48, the piston B49 and the rectangular strip 43, and in the process that the V-shaped plate 42 moves downwards rapidly, the extrusion force of the V-shaped plate 42 to the third rotating shaft 34 is large, so that the thrust force transmitted to the piston B49 by the third rotating shaft 34 through the V-shaped plate 42 and the rectangular strip 43 is large, and the pressure of the piston B49 on the non-Newtonian fluid is large; according to the characteristics of the non-Newtonian fluid, the V-shaped plate 42 is difficult to push the B piston 49 to move towards the direction of the brake bar 40 through the rectangular bar 43; because the brake bar 40 moves downwards rapidly to have larger extrusion force on the third rotating shaft 34, the reverse thrust of the second spring 26 is overcome, and then the V-shaped plate 42 moves rapidly downwards to push the third rotating shaft 34 to move towards the flywheel 38 in an extrusion mode, the third rotating shaft 34 drives the sliding block 24 to move towards the flywheel 38, the sliding block 24 drives the second guide block 25 to move towards the flywheel 38, and the second spring 26 is compressed continuously; during this time, the third shaft 34 moves relatively upward along the corresponding plate surface of the V-shaped plate 42. When the sliding block 24 slides towards the direction of the flywheel 38, the sliding block 24 drives the telescopic inner shaft 30 to slide in the outer sleeve shaft 29 through corresponding bearings in the Z-shaped plate 32, the Z-shaped plate 32 enables the positions of the telescopic inner shaft 30 and the third rotating shaft 34 to be kept relatively static, and the bevel teeth 55 in the bevel tooth combination 33 are always in an engaged state. In the process that the brake bar 40 moves downwards rapidly, the third rotating shaft 34 moves towards the flywheel 38, so that the friction wheel 35 can be pressed and contacted with the flywheel 38, at the moment, the rapidly rotating flywheel 38 drives the fourth gear 31 to rotate more rapidly anticlockwise through the friction wheel 35, the third rotating shaft 34, the bevel gear combination 33 and the telescopic shaft 28, and the fourth gear 31 drives the third gear 19 to rotate more rapidly clockwise; since the one-way clutch 20 has an overrunning effect, when the third gear 19 rotates more rapidly in the clockwise direction, the clockwise rotation speed of the third gear 19 exceeds the clockwise rotation speed of the second gear 18, and then the third gear 19 rotates more rapidly clockwise to make the brake connecting plate 6 move downwards more rapidly. In the whole process of rapidly stepping on the brake pedal 1, under the condition that the downward moving distance of the brake strip 40 is equal to the downward moving distance of the brake connecting plate 6, the downward moving speed of the brake connecting plate 6 is greater than the downward moving speed of the brake strip 40, and the more rapid downward movement of the brake connecting plate 6 enables a brake module at an automobile tire to rapidly perform emergency braking action. When the brake connecting plate 6 moves downwards to the extreme position, the third gear 19 continuously shifts the teeth of the first rack 7 close to one end of the pedal base 4. When the brake pedal 1 is moved down to the extreme position, the brake strip 40 is also moved down to the extreme position, at which time the brake link plate 6 is moved down to the extreme position ahead of the brake strip 40. In the process of sudden braking, due to the overrunning action of the one-way clutch 20, the clockwise rotating speed of the third gear 19 is greater than the clockwise rotating speed of the second gear 18, the downward moving distance of the brake connecting plate 6 is equal to the downward moving distance of the brake strip 40, and the downward moving speed of the brake connecting plate 6 is greater than the downward moving speed of the brake strip 40, so that the effect of rapidly stepping on the brake pedal 1 is faster than that of the traditional rapid stepping on the brake pedal 1.

When the driver no longer steps on the brake pedal 1, under the reset action of the telescopic rod spring 3, the brake pedal 1 moves upwards, and the brake pedal 1 drives the brake strip 40 to move upwards for resetting. When the brake bar 40 starts to move upwards for resetting, the brake bar 40 drives the V-shaped plate 42 to move upwards through the shell B48, the piston B49 and the rectangular bar 43, so that the V-shaped plate 42 is not extruded to push the third rotating shaft 34 actively any more, then under the resetting action of the second spring 26, the second guide block 25 drives the friction wheel 35 to move rapidly for resetting in the direction away from the flywheel 38 through the slide block 24 and the third rotating shaft 34, and during the resetting, the third rotating shaft 34 moves downwards along the corresponding plate surface of the V-shaped plate 42 relatively; because the friction wheel 35 moves away from the flywheel 38 to reset, the friction wheel 35 is no longer in pressing contact with the flywheel 38, and the flywheel 38 which rotates fast does not drive the third gear 19 to rotate clockwise through the friction wheel 35, the third rotating shaft 34, the bevel gear combination 33, the telescopic shaft 28 and the fourth gear 31. In the process that the brake pedal 1 drives the brake bar 40 to move upwards and reset, the brake bar 40 drives the first gear 17 to rotate clockwise through the second gear 41, and the first gear 17 drives the second rotating shaft 16 to rotate anticlockwise through the second gear 18. Because the one-way clutch 20 also has a one-way function, that is, when the second rotating shaft 16 rotates clockwise, the second rotating shaft 16 can drive the third gear 19 to rotate clockwise via the one-way clutch 20, and when the second rotating shaft 16 rotates counterclockwise, the second rotating shaft 16 cannot drive the third gear 19 to rotate counterclockwise via the one-way clutch 20. Because the second rotating shaft 16 can not drive the third gear 19 to rotate counterclockwise through the one-way clutch 20, the third gear 19 can not drive the first rack 7 to move upward to reset, however, under the reset action of the first spring 9, the first guide block 8 drives the brake connecting plate 6 to move upward to reset, so that the third gear 19 rotates counterclockwise.

In the invention, the speed reducing motor 36 is small, so that the cost of the speed reducing motor 36 is lower, and the small speed reducing motor 36 is more convenient for space arrangement; for the flywheel 38, after the speed reducing motor 36 is driven for a period of time, the rotating speed of the flywheel 38 can reach the fastest speed, the flywheel 38 can store huge rotating energy, and the huge rotating energy on the flywheel 38 can instantly rotate the friction wheel 35 at an ultra-high speed, so that the smooth operation of the invention is ensured.

In conclusion, the invention has the main beneficial effects that: due to the design of the structures such as the non-Newtonian fluid, the V-shaped plate, the friction wheel, the flywheel and the like, when the traditional slow brake is carried out, the V-shaped plate can not push the friction wheel to move towards the flywheel direction through the third rotating shaft due to the characteristics of the non-Newtonian fluid; in the slow braking process, the downward moving speed of the brake strip and the brake connecting plate is the same, and the slow braking effect of the slow brake is the same as that of the traditional slow brake. When emergency braking is needed, due to the characteristic of the non-Newtonian fluid, the V-shaped plate can push the friction wheel to move towards the flywheel through the rotating shaft, and the flywheel drives the third gear to rotate clockwise more rapidly through the friction wheel, the third rotating shaft, the bevel gear combination, the telescopic shaft and the fourth gear; because the one-way clutch has the overrunning function, when the third gear rotates clockwise, the clockwise rotation speed of the third gear exceeds the clockwise rotation speed of the second gear, and the third gear rotates clockwise rapidly, so that the downward movement speed of the brake connecting plate is higher; in the emergency braking process, the brake connecting plate moves downwards faster than the brake strip, so that the action speed of the emergency brake is faster than that of the traditional emergency brake, and the brake system can perform emergency braking faster. The braking system has the advantages that the emergency braking time of the braking system is shorter than that of a traditional automobile, the automobile can be braked emergently after meeting an emergency, the possibility that a driver touches the accident after the driver suddenly steps on the brake in an emergency is reduced, and the safety of the driver is protected. The invention has simple mechanism and better use effect.
