Description

Technical Field

[0001] This utility model relates to a clutch booster, and more particularly to a split-type leak-proof multi-chamber clutch booster. Background Technology

[0002] A clutch booster is a device used to reduce the force required for the driver to operate the clutch pedal. It is especially common in heavy-duty vehicles or high-performance cars. The main function of a clutch booster is to reduce the force required to disengage the clutch by adding mechanical, hydraulic or pneumatic assistance, making the gear shifting process easier and smoother.

[0003] Current clutch boosters are mainly single-chamber designs. The booster's force is applied to one side of the piston plate. This one-sided pressure can cause uneven stress on the piston plate, which can easily lead to local stress concentration. Especially under high-pressure working conditions, this stress concentration may cause the piston plate to deform or be damaged, affecting the stability of the entire clutch booster. Utility Model Content

[0004] In view of this, the present invention provides a split-type leak-proof multi-chamber clutch booster, which can overcome the disadvantage that pressure applied on one side will cause uneven force on the piston plate, resulting in local stress concentration. This stress concentration may cause deformation or damage to the piston plate, affecting the stability of the entire clutch booster.

Four partition plates 4 are evenly spaced inside the annular plate 3. The mounting sleeve 5 is connected between the four partition plates 4. The partition plates 4 divide the interior of the annular plate 3 into four chambers. A piston plate 6 is slidably and sealingly connected to each chamber. Two springs 7 are connected between the right side of the piston plate 6 and the right side of the second outer shell 2. A slider 8 is slidably connected to the middle of the right side of the second outer shell 2. The fixed shaft 9 is slidably connected inside the slider 8. The slider 8 drives the piston plate 6 to move through the transmission mechanism. The protective mechanism is used to seal the left side of the annular plate 3.

[0024] Reference Figure 4 and Figure 5The transmission mechanism includes a movable sleeve 10, a movable disk 11, a movable frame 12, a connecting frame 13, a telescopic rod 14, a spur gear 15, and a spur rack 16. The movable sleeve 10 is slidably connected to the left end of the fixed shaft 9. The movable disk 11 is connected to the outside of the movable sleeve 10. Four movable frames 12 are evenly spaced around the movable disk 11. The left side of the movable frame 12 is connected to the right side of the piston plate 6. Four connecting frames 13 are evenly spaced around the inside of the outer shell 2. The ends of the four connecting frames 13 that are close to each other are hinged to a telescopic rod 14. All four telescopic rods 14 are hinged to the movable disk 11. Spur gears 15 are connected to the telescopic rods 14. Four spur racks 16 are evenly spaced around the outside of the slider 8. The spur racks 16 and spur gears 15 mesh.

[0025] Reference Figures 6-9 The protective mechanism includes a connecting plate 17, a connecting ring 18, a baffle 19, a rotating assembly, and a ventilation assembly. The connecting plate 17 is connected to the middle left side of the outer casing 1, and the connecting ring 18 is connected to the middle right side of the connecting plate 17. The baffle 19 is rotatably connected to the outer circumference of the connecting ring 18 at uniform intervals. The rotating assembly is used to drive the baffle 19 to rotate, thereby controlling the opening and closing of the baffle 19. The ventilation assembly is used to ventilate the inside of the annular plate 3.

[0026] Reference Figures 7-9 The rotating assembly includes a rotating shaft 20, a spiral shaft 21, and a protrusion 22. The rotating shaft 20 is rotatably connected inside the mounting sleeve 5. The rotating shaft 20 and the baffle 19 are driven by a bevel gear. The right end of the rotating shaft 20 is connected to the spiral shaft 21. The spiral shaft 21 is located inside the movable sleeve 10, and the right end of the spiral shaft 21 is rotatably connected to the left end of the fixed shaft 9. The top of the movable sleeve 10 is connected to the protrusion 22.

[0027] Reference Figure 6 The ventilation assembly includes an air inlet pipe 23 and a one-way valve 24. Twelve air inlet pipes 23 are evenly spaced around the outer circumference of the annular plate 3. A one-way valve 24 is installed on each air inlet pipe 23. Both the air inlet pipe 23 and the one-way valve 24 penetrate the outer shell 1. Under the action of the one-way valve 24, outside air can enter the annular plate 3 through the air inlet pipe 23, and the air inside the annular plate 3 cannot be discharged through the air inlet pipe 23.

[0028] Reference Figure 2 It also includes convex strips 25. Four convex strips 25 are evenly spaced around the outer circumference of the slider 8. The convex strips 25 are slidably connected to the right side of the outer shell 2. The convex strips 25 can prevent the slider 8 from rotating.

[0029] This clutch booster is installed inside the car. The slider 8 is connected to the clutch pedal, and the fixed shaft 9 is connected to the interior of the car. When the clutch pedal is depressed, it moves the slider 8 to the left. The slider 8 then moves the rack 16 to the left, which in turn rotates the spur gear 15. The spur gear 15 rotates the telescopic rod 14, which in turn moves the moving disc 11 to the left. Simultaneously, the telescopic rod 14 shortens, causing the moving disc 11 to move to the left, which in turn moves the moving sleeve 10 to the left. The moving sleeve 10 then moves the protrusion 22 to the left, causing the protrusion 22 to... The rotating screw shaft 21 rotates, driving the rotating shaft 20 to rotate. The rotating shaft 20, through a bevel gear, drives the baffle 19 to rotate, opening the baffle 19 and ensuring that the air inside the annular plate 3 can be discharged. The moving disc 11 moves to the left, which also drives the moving frame 12 to move to the left. The moving frame 12 drives the piston plate 6 to move to the left, allowing the air inside the annular plate 3 to be discharged through the left side of the outer casing 1, providing assistance. The spring 7 is stretched, and there are four chambers in total, which can avoid uneven force on the piston plate 6, thereby preventing deformation or damage to the piston plate 6 and ensuring the entire clutch booster. To ensure stability, when the clutch pedal is released, the clutch pedal causes the slider 8 to move to the right. The slider 8 then causes the rack 16 to move to the left. The rack 16 causes the spur gear 15 to rotate in the opposite direction. The spur gear 15 causes the telescopic rod 14 to rotate in the opposite direction. The telescopic rod 14 causes the moving disk 11 to move to the right. Simultaneously, the telescopic rod 14 shortens, and the moving disk 11 moves to the right, causing the moving sleeve 10 to move to the right. The moving sleeve 10 causes the protrusion 22 to move to the right, and the protrusion 22 causes the spiral shaft 21 to rotate in the opposite direction. The spiral shaft 21 then causes the rotating shaft 20 to rotate in the opposite direction. 20 drives the baffle 19 to rotate in the opposite direction via the bevel gear, closing the baffle 19 and preventing impurities from seeping into the annular plate 3, which would make it difficult for the piston plate 6 to slide. The movement of the moving disc 11 to the right can also drive the moving frame 12 to the right. The moving frame 12 drives the piston plate 6 to the right. Under the action of the spring 7, the movement of the piston plate 6 to the right can be assisted. Outside air enters into the annular plate 3 through the air intake pipe 23. The outer shell 1 and the outer shell 2 are connected by bolts and can be separated to facilitate the inspection and maintenance of the internal components of the outer shell 1 and the outer shell 2.
