Description

Technical Field

[0001] The invention relates to the field of clutches, and in particular to a self-lubricating clutch for an automobile. Background Art

[0002] When the car clutch is in use, the driver presses the clutch pedal to compress the diaphragm spring inward, causing the outer edge of the diaphragm spring to flip outward, thereby driving the pressure plate away from the flywheel, separating the clutch plate from the flywheel, and causing the flywheel to idle.

[0003] However, when the clutch pedal is stepped on, the diaphragm spring is mainly compressed by the release sleeve, and the release sleeve is slidably arranged on the driven shaft. The driver often encounters difficulty when stepping on the clutch pedal. This is because the lubricating oil between the release sleeve and the driven shaft is reduced, and the friction force is increased. The release sleeve needs to be lubricated. However, in the prior art, the lubricating oil is generally added manually between the release sleeve and the driven shaft, which is inconvenient to operate.

[0004] In view of this, the inventor, after in-depth research, came up with this case. Summary of the invention

[0005] (1) Technical issues to be solved

[0006] In view of the problems of the prior art, the present invention provides an automobile self-lubricating clutch to solve the problem that the release sleeve of the clutch in the prior art needs to be manually added with lubricating oil.

[0007] (2) Technical solution

[0008] In order to solve the above problems, the present invention provides a self-lubricating clutch for an automobile, comprising a clutch body, wherein a lubricating oil squeezing sleeve is slidably connected to the left end of a separation sleeve of the clutch body, a lubricating oil soaked sponge is provided in the lubricating oil squeezing sleeve, the right end of the lubricating oil soaked sponge is fixedly connected to the separation sleeve, and a stopper is provided at the left end of the lubricating oil squeezing sleeve which is in close contact with the lubricating oil soaked sponge.

[0009] Preferably, the stopper is fixed with a damping ring which is slidably sleeved on the driven shaft.

[0010] Preferably, the diameter of the inside of the lubricating oil squeezing sleeve gradually increases from left to right, and the shape of the lubricating oil-soaked sponge is consistent with the shape of the inside of the lubricating oil squeezing sleeve.

[0011] Preferably, a limit block for limiting the lubricating oil extrusion sleeve from sliding out is provided at the left end of the separation sleeve, and a spring is connected to the limit block and the right end of the lubricating oil extrusion sleeve.

[0012] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a simple structure and a novel concept. A lubricating oil-soaked sponge is arranged in the separation sleeve of the existing diaphragm clutch, and a lubricating oil squeezing sleeve is slidably arranged at the left end of the separation sleeve, so that when the lubricating oil between the separation sleeve and the driven shaft is insufficient and the friction force is relatively large, when the driver steps on the clutch pedal and the separation sleeve slides, a relative sliding occurs with the lubricating oil squeezing sleeve, so that the lubricating oil squeezing sleeve squeezes the lubricating oil-soaked sponge, so that the lubricating oil in the lubricating oil-soaked sponge is smeared on the driven shaft, thereby realizing the function of automatically adding lubricating oil.

[0015] Figure 3 It is a schematic diagram of the structure of the lubrication mechanism of the present invention.

[0016] In the figure: 1 clutch plate, 2 pressure plate, 3 flywheel, 4 diaphragm spring, 5 driven shaft, 6 damping ring, 7 limit block, 8 lubricating oil extrusion sleeve, 9 inclined surface, 10 spring, 11 lubricating oil soaked sponge, 12 release sleeve. DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-3 The present invention provides a self-lubricating clutch for an automobile, comprising a clutch body, a separation sleeve 12 being slidably arranged on a driven shaft 5 of the clutch body, a lubricating oil squeezing sleeve 8 being slidably connected to the inner side of the separation sleeve 12 close to the flywheel 3, a lubricating oil soaked sponge 11 being arranged on the inner wall of the lubricating oil squeezing sleeve 8, the right end of the lubricating oil soaked sponge 11 being fixedly connected to the separation sleeve 12, the lubricating oil soaked sponge 11 and the lubricating oil squeezing sleeve 8 being both sleeved on the driven shaft 5, the inner end of the lubricating oil squeezing sleeve 8 being open and the inner wall of the outer end being provided with a stopper, the stopper being in close contact with the outer end of the lubricating oil soaked sponge 11 and being fixed with a damping ring 6.

[0019] The working conditions of the above structure are described in detail below. When in use, the driver steps on the clutch pedal to slide the release sleeve 12 to the left. When there is enough lubricating oil between the release sleeve 12 and the driven shaft 5 and the friction force is relatively small, the lubricating oil-soaked sponge 11 and the lubricating oil squeezing sleeve 8 move together with the release sleeve 12. When there is insufficient lubricating oil between the release sleeve 12 and the driven shaft 5, the friction force when sliding between the damping ring 6 and the driven shaft 5 increases, so that when the release sleeve 12 slides to the left, the lubricating oil squeezing sleeve 8 slides to the right relative to the release sleeve 12, thereby squeezing the lubricating oil-soaked sponge 11, so that the lubricating oil in the lubricating oil-soaked sponge 11 is squeezed onto the surface of the driven shaft 5, which plays a role of automatic lubrication.

[0020] Furthermore, a flange is integrally formed at the inner end of the lubricating oil extrusion sleeve 8, and a stopper 7 is provided at the left end of the separation sleeve 12 to limit the lubricating oil extrusion sleeve 8 from sliding out. A spring 10 is fixed between the stopper 7 and the flange. After the lubricating oil is applied to the surface of the driven shaft 5, the lubricating oil extrusion sleeve 8 slides to its original position in the separation sleeve 12 under the elastic force of the spring 10.

[0021] Furthermore, the diameter of the lubricating oil squeezing sleeve 8 gradually increases from left to right, and the lubricating oil soaked sponge 11 is consistent with the shape of the internal space of the lubricating oil squeezing sleeve 8, and is penetrated by a hole in the middle and is sleeved on the driven shaft 5. Such a design makes the friction between the separation sleeve 12 and the driven shaft 5 relatively large, and when the separation sleeve 12 slides to the left, the inclined part of the lubricating oil squeezing sleeve 8 can squeeze the lubricating oil soaked sponge 11 from the side, so that the lubricating oil soaked sponge 11 has a larger area of ​​​​lubricating oil on the driven shaft 5.

[0022] In the description of the present invention, it is necessary to understand that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
