Manual transmission interlock cage and manual transmission

Abstract

The invention belongs to the field of automobile transmissions and particularly relates to a manual transmission interlock cage and a manual transmission. The interlock cage is provided with a limiting slot or limiting hole in the top, the limiting slot or limiting hole is elongated, the length direction of the limiting slot or limiting hole is consistent with the axial direction of shifting shaft through holes, the length of the limiting slot or limiting hole is greater than or equal to a selection travel of a shifting head, and a limiting block arranged on a shifting mechanism case and capable of relatively moving in the limiting slot or limiting hole along the length direction of the limiting slot or limiting hole is extended into the limiting slot or limiting hole. The limiting slot or limiting hole and the limiting block have high machining precision and high strength and hardness, a fitting clearance between the limiting slot or limiting hole and a limiting pin is small, and the limiting pin experiences small sliding loss in the limiting slot or limiting hole; therefore, it is ensured that the interlock cage may be kept vertical constantly, and it is avoided that excessive manual shifting force leads to damage of the shifting mechanism case and affects the gear interlocking function.

Description

technical field [0001] The invention belongs to the field of automobile transmissions, and in particular relates to a manual transmission interlock cage and a transmission. Background technique [0002] The interlock cage is mainly used in the gear selection mechanism of manual transmission. The position of the interlock cage in the gear selection mechanism is mainly set on the outside of the shift dial, and is sleeved on the shift shaft together with the shift dial. And can move axially on the shift shaft together with the shift paddle. The shift paddle is splined with the shift shaft and can rotate together with the shift shaft. The interlock cage is empty on the shift shaft. At the same time, the top of the interlock cage is embedded in the aluminum shift mechanism housing. In the limiting groove, prevent the interlock cage from swinging back and forth. [0003] The main function of the interlock cage is that when the transmission selects and shifts gears, the rotation ...

Problems solved by technology

In this case, the method of using the limit groove and the interlock cage body to cooperate with the limit is time-consuming and laborious and the effect is not good

[0010] Therefore, in view of the inaccurate limit of the existing interlock cage in the aluminum shift mechanism housing of the manual transmission, the long-term use causes the limit groove of the aluminum select shift mechanism housing to wear, causing the interlock cage to be in front of and behind the shift fork groove. Swing, the interlock effect is reduced, and there is a risk of damage to the transmission body and a decrease in comfort when selecting and shifting. It is necessary to carry out research and innovation on the existing interlock cage
