It should be noted that, if directional indication is involved in the embodiment of the present invention, the directional indication is only used for explaining the relative positional relationship, the motion situation, and the like between the components in a certain posture, and if the certain posture is changed, the directional indication is changed accordingly.

In addition, if there is a description of "first", "second", etc. in an embodiment of the present invention, the description of "first", "second", etc. is for descriptive purposes only and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

The existing clutch main pump assembly generally comprises a clutch pedal, a main pump, a hydraulic pipeline, a release bearing and a clutch, a driver pushes a clutch main pump push rod to establish pipeline pressure by stepping on the clutch pedal, the combination and the separation of the clutch are realized, however, the vibration of feet of the driver is often heavier when the clutch pedal is stepped on, and the driving comfort is influenced.

In view of the above, the invention provides a clutch main pump for reducing vibration and improving pedal comfort and a vehicle provided with the clutch main pump. Fig. 1 to 6 show an embodiment of a clutched main pump provided by the present invention.

Referring to fig. 1 and fig. 2, the clutch main pump 1000 includes a main pump 1 and a push rod 2, the main pump 1 includes a pump body and a piston disposed in the pump body, one end of the push rod 2 is connected to the piston, the other end of the push rod 2 is used to connect a clutch pedal 3, and the push rod 2 is provided with a counterweight 21. When the oil pressure was undulant for main pump 1, undulant edge the length direction transmission of push rod 2, push rod 2 has been increased balancing weight 21 makes the whole quality of push rod 2 increases, and the quality is big more, and inertia is big more, and the state is difficult for changing more, reaches when the vibration during push rod 2, because the quality increases the motion state change of push rod 2 slows down relatively, so balancing weight 21 plays the cushioning effect, alleviates the undulant vibration transmission that leads to of 1 oil pressure of main pump improves driver's driving comfort level.

Further, if the mass of the counterweight 21 is too low, a good buffering effect cannot be achieved, and the too high mass increases the force required by the driver for treading the pedal, so that when the mass of the counterweight 21 is within the range of more than or equal to 0.5Kg and less than or equal to 1.0Kg, buffering and labor saving can be achieved, and preferably, the mass of the counterweight 21 is within the range of more than or equal to 0.5Kg and less than or equal to 0.6 Kg.

Further, referring to fig. 2, the push rod 2 includes a rod 22 and an adjusting structure 23, one end of the rod 22 is connected to the piston, the other end of the rod 22 is connected to the clutch pedal 3 through the adjusting structure 23, and the adjusting structure 23 is used for adjusting a distance between the piston and the clutch pedal 3, that is, the rod 22 and the adjusting structure 23 cooperate to adjust an overall length of the push rod 2. When the size precision of the parts for assembling the clutch main pump 1000 and the clutch pedal 3 is low, the clutch idle stroke is zero, and the main pump 1 cannot feed oil, so that the clutch system fails, the total length of the push rod 2 can be shortened by matching the rod body 22 and the adjusting structure 23 to reserve the clutch idle stroke, so that the problem of failure of the clutch system due to poor consistency of the parts during assembly is avoided, and the one-time assembly rate is improved. In addition, the weight 21 is disposed on the shaft 22 or the adjusting structure 23, so that the weight 21 can be disposed at a more flexible position.

The balancing weight 21 is arranged on the rod body 22 or the adjusting structure 23, the arrangement form of the balancing weight 21 is not limited, and the balancing weight can be used as long as the overall mass of the push rod 2 can be increased and the buffering effect is achieved. For example, the weight 21 may be provided on the shaft 22 and integrally formed with the shaft 22, so that the shaft 22 and the weight 21 can be integrally produced, and the number of processing steps can be reduced. In another embodiment, a plurality of the weights 21 may be simultaneously disposed on the shaft 22 and/or the adjusting structure 23. In yet another embodiment, the weight 21 may be detachably disposed on the shaft 22 or the adjusting structure 23 to facilitate replacement and adjustment of the weight 21 when it is worn or has a mismatch in size.

Further, referring to fig. 3 to 5, in this embodiment, the adjusting structure 23 includes a connecting socket 231 and a locking component 232 mounted on the connecting socket 231, the connecting socket 231 is telescopically sleeved on an end of the shaft 22 away from the piston, and the locking component 232 is used for limiting a relative position of the shaft 22 and the connecting socket 231. The relative positions of the shaft 22 and the connecting sleeve 231 are limited by the locking component 232, so that the shaft 22 and the adjusting structure 23 are matched to flexibly adjust the overall length of the push rod 2.

The specific structure of the locking assembly 232 may be various as long as the relative position between the shaft 22 and the connecting sleeve 231 can be limited, in this embodiment, please refer to fig. 4 and 5, the connecting sleeve 231 has a mounting cavity 2312, the shaft 22 extends into the mounting cavity 2312 from one end of the mounting cavity 2312, one side of the mounting cavity 2312 has an opening, the locking assembly 232 includes a limit block 2321, the limit block 2321 is disposed on the connecting sleeve 231, and one side of the limit block 2321 extends into the mounting cavity 2312 from the opening, an end surface of the limit block 2321 extending into the mounting cavity 2312 is provided with an arc-shaped groove, and the shape of the arc-shaped groove is adapted to the shaft 22 so as to press and abut against the shaft 22. So that the stopper 2321 is fitted with the shaft 22 through the arc-shaped groove to define the relative position of the shaft 22 and the connecting socket 231, the structure of the stopper 2321 is simple and convenient to define and adjust the relative position of the shaft 22 and the connecting socket 231.

The form of the arc-shaped groove and the shaft 22 is not limited as long as the arc-shaped groove can be pressed against the shaft 22. In this embodiment, referring to fig. 3 and 5, the arc-shaped groove is provided with an internal thread, and the shaft 22 is provided with an external thread adapted to the internal thread of the arc-shaped groove, so that the arc-shaped groove presses against the shaft 22, and the fine adjustment of the total length of the push rod 2 can be realized through thread matching.

Further, referring to fig. 4 and fig. 5, in order to prevent the limiting block 2321 from being separated from the installation cavity 2312, the adjusting structure 23 includes a sliding rod 2311 extending from one end of the connection sleeve 231 toward the opening, the sliding rod 2311 and the opening are located on the same side of the connection sleeve 231, the locking assembly 232 further includes a lock 2322, the lock 2322 is provided with a sliding slot 2322a, the lock 2322 is slidably disposed on the sliding rod 2311 through the sliding slot 2322a, and when the lock 2322 slides to an end of the sliding rod 2311 close to the opening, the limiting block 2321 is pressed and buckled on a side of the limiting block 2321 protruding out of the installation cavity 2312.
