Description

Technical Field

[0001] The present application relates to the field of clutches, and in particular to a clutch assembly and a vehicle. Background Art

[0002] The clutch control structure of medium and heavy-duty vehicles usually adopts pneumatic assistance, using compressed air as the power source to assist the clutch control mechanism to move and help the clutch to disengage.

In addition, the capacity of a single air reservoir is limited, and after long-term operation, it may not be able to provide sufficient air pressure for the pneumatic assisted clutch operating mechanism.

[0004] Therefore it is necessary to provide a novel clutch assembly and vehicle to solve the above problems. Utility Model Content

[0027] Next, the embodiments of this specification are described in detail.

[0028] Please refer to Figures 1 to 3 As shown, the present application provides a clutch assembly, including: a clutch, a clutch sub-cylinder 10, a first air reservoir 20 and a second air reservoir 30. The first air reservoir 20 and the second air reservoir 30 are respectively connected to the clutch sub-cylinder 10, and respectively supply air to the clutch sub-cylinder 10. The clutch sub-cylinder 10 controls the clutch to be separated or engaged.

[0029] The clutch assembly of the present application is provided with a first air cylinder 20 and a second air cylinder 30, and the first air cylinder 20 and the second air cylinder 30 respectively supply air to the clutch sub-pump 10, thereby solving the problem that the clutch sub-pump 10 cannot control the clutch to open or close due to insufficient air supply when only one air cylinder is provided; at the same time, providing multiple air cylinders can increase the air storage capacity of the clutch assembly, thereby solving the problem that a single air cylinder cannot provide sufficient air pressure for the clutch sub-pump 10 due to insufficient air storage.

[0030] In one embodiment, see Figure 1 As shown, the first air reservoir 20 and the second air reservoir 30 supply air to the clutch sub-pump 10 respectively.

[0031] A control valve 40 is provided between the second air reservoir 30 and the clutch sub-pump 10. The control valve 40 is normally closed, at which time the second air reservoir 30 is not connected to the clutch sub-pump 10, and the clutch sub-pump 10 is only supplied with air through the first air reservoir 20.

[0032] When the first air cylinder 20 fails to supply air or there is an air leak in the air supply pipeline between the first air cylinder 20 and the clutch sub-pump 10, the control valve 40 opens, the second air cylinder 30 is connected to the clutch sub-pump 10, and the second air cylinder 30 supplies air to the clutch sub-pump to replenish the first air cylinder 20.

[0033] In another embodiment, see Figures 2 to 3 As shown, the first air reservoir 20 supplies air to the clutch cylinder 10 and the second air reservoir 30 at the same time. A first one-way valve 50 is arranged between the first air reservoir 20 and the second air reservoir 30, and the first air reservoir 20 and the second air reservoir 30 are connected through the first one-way valve 50, and the first air reservoir 20 supplies air to the second air reservoir 30. When the first air reservoir 20 supplies air to the clutch cylinder 10, it also supplies air to the second air reservoir 30 through the first one-way valve 50.

[0034] The first gas cylinder 20 is used as a gas source to supply gas to the second gas cylinder 30. The second gas cylinder 30 stores part of the gas provided by the first gas cylinder 20. When the first gas cylinder 20 leaks or fails, it is used as a backup gas source to supply gas to the clutch sub-pump 10. This arrangement only requires the first gas cylinder 20 to be inflated when the gas cylinders are inflated, and does not require the first gas cylinder 20 and the second gas cylinder 30 to be inflated at the same time, which is more convenient.

[0035] In this embodiment, the control valve 40 and the first one-way valve 50 are respectively located at the opposite ends of the second gas cylinder 30. The second gas cylinder 30 takes in air through the first one-way valve 50 and exhausts air through the control valve 40. The air inlet and the air outlet are respectively located at the opposite ends of the second gas cylinder 30, which can realize the gas diversion effect and help the gas to be evenly distributed in the second gas cylinder 30; it can reduce the pressure fluctuation of the second gas cylinder 30 and improve the stability of the second gas cylinder 30; the control valve 40 and the first one-way valve 50 are respectively located at the opposite ends of the second gas cylinder 30, which is convenient for maintenance and inspection of the second gas cylinder 30, the control valve 40 and the first one-way valve 50.

[0036] The control valve 40 described in the present application may be a manual valve or an automatic valve.

[0037] When the control valve 40 is an automatic valve, the clutch assembly described in the present application further includes an air pressure monitoring device 60 and a control device 70. The air pressure monitoring device 60 detects the air pressure of the first air reservoir 20, and the control device 70 is connected to the control valve 40 and controls the control valve 40 to open or close according to the air pressure value detected by the air pressure monitoring device 60.

[0038] When the air pressure monitoring device 60 detects that the air pressure of the first air cylinder 20 is less than the preset air pressure, the control device 70 controls the control valve 40 to open. When the air pressure monitoring device 60 detects that the air pressure of the first air cylinder 20 is greater than or equal to the preset air pressure, the control device 70 controls the control valve 40 to close. The preset air pressure described in this application is 0.7 MPa.

[0039] The present application also provides a vehicle, including a gas-using device 80 and the above-mentioned clutch assembly. The gas-using device 80 includes a brake cylinder, a pneumatic shock absorber, an air bag, an air horn, an air compressor and other devices in the vehicle that need to use gas.

[0040] Please refer to Figure 4 As shown, the gas-using device 80 is connected to the first gas cylinder 20, and the first gas cylinder 20 serves as the gas source of the vehicle to supply gas to all devices in the vehicle that need to use gas.

[0041] Since the vehicle usually only uses the first air reservoir 20 as the air source to supply air to the devices in the vehicle that need to use air, if the air tightness of any auxiliary air pipe decreases or there is air usage, the air pressure of the whole vehicle will drop, which cannot meet the air supply pressure requirement of the clutch sub-pump 10, making the clutch sub-pump 10 unable to work normally and the clutch unable to be disengaged. Therefore, the clutch assembly of the present application is provided with a first air reservoir 20 and a second air reservoir 30, and the second air reservoir 30 can replenish air for the clutch sub-pump 10 when the air supply pressure is insufficient, thereby solving the above problem.

[0042] The vehicle described in the present application further includes a second one-way valve 90, which is disposed between the first air reservoir 20 and the clutch sub-pump 10. Since the first air reservoir 20 not only supplies air to the clutch sub-pump 10, but also supplies air to the air-using device 80, when the first air reservoir 20 has a fault such as leakage, resulting in a decrease in air pressure, if the second one-way valve 90 is not disposed between the first air reservoir 20 and the clutch sub-pump 10, after the second air reservoir 30 replenishes air to the clutch sub-pump 10, the gas in the clutch sub-pump 10 will flow back from the clutch sub-pump 10 to the air-using device 80 due to the air pressure difference, thereby resulting in a waste of air supply from the second air reservoir 30.
