Vehicle gear selection mechanism and automobile

Abstract

The invention provides an automobile gear selecting and shifting mechanism, which comprises a gear selecting and shifting lever, a bulb protecting sleeve, a bulb and an oil storage unit, wherein the bulb can be embedded into the bulb protecting sleeve, is arranged at one end of the gear selecting and shifting lever and is driven to rotate in the bulb protecting sleeve by means of movement of the gear selecting and shifting lever. Lubricating greases are stored in the oil storage unit and can enter the space between the outer surface of the bulb and the inner wall surface of the bulb protecting sleeve. The automobile gear selecting and shifting mechanism solves the problem that an automobile gear selecting and shifting mechanism in the prior art needs to be frequently added with lubricating greases, and avoids abrasion of parts caused by decrease of the lubricating greases.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to a vehicle gear selection mechanism and an automobile with the vehicle gear selection mechanism. Background technique [0002] The working principle of the automobile transmission is to expand the range of driving force and speed of the automobile by changing the transmission ratio to meet different driving conditions. With the continuous development of automobile technology, the requirements for the shifting quality of the transmission are getting higher and higher. [0003] At present, the general-purpose vehicle gear selection mechanism in automobiles generally smears lubricating grease between the ball head body and the ball head sheath connected with the gear selection lever during its work, and the ball head body and the ball head sheath are oiled by the lubricating grease. Lubricate when there is relative movement between them, so as to improve ...

AI Technical Summary

Problems solved by technology

In actual operation, grease is usually applied on the outer surface of the ball head body 12 or the inner wall surface of the ball head sheath 13 for lubrication, but since there is no continuous oil supply structure to supply grease to the two, the ball head body and The amount of lubricating grease between the ball bushes is limited, so it is often necessary to add, and the adding method of lubricating grease is currently manually added, which brings a lot of trouble to the use of the shift mechanism

When adding lubricating grease, due to manually applying lubricating grease on the outer surface of the ball head body 12 or the inner wall surface of the ball head sheath 13, the coating thickness of the lubricating grease will inevitably be uneven. During use, For lubricating grease with a large coating thickness, due to the rotation of the ball head body 12, a part of the excess lubricating grease remaining on the inner wall surface of the ball head sheath 13 is prone to air-drying loss because it does not contact the ball head body 12 , resulting in unnecessary waste

In addition, due to the uneven coating thickness of the lubricating grease, as the number of shifts increases, there will be a part of the area between the ball head body 12 and the ball head sheath 13 that is less thickly coated with lubricating grease, resulting in a lack of lubricating grease in the ball head. The lubrication between the body 12 and the ball head sheath 13 is insufficient, and the lubricating grease is air-dried in the air. After a long time of use, there will be abnormal noises between the ball head body 12 and the ball head sheath 13, and the gear will be shifted. Astringency and other problems
