Problems solved by technology

Especially for transverse engines, due to the limited space, the multi-gear gearbox cannot meet the needs
Although Honda has developed a 10AT gearbox that can be used with transverse engines, the axial length has been reduced, but its structure is more complicated, and the problems of large volume and heavy weight have not been well improved

Abstract

The invention relates to the technical field of gearboxes, in particular to a gearbox with an internal support gear shifting mechanism. The gearbox comprises a gearbox body, a power input shaft, a power output shaft and a clutch; a gear shifting output shaft I and a gear shifting output shaft II are arranged in parallel in the gearbox body; the gear shifting output shaft I and the gear shifting output shaft II respectively comprise a solid section and a hollow section; the solid section is sleeved with fixed gears with the diameters increasing or decreasing in sequence; the hollow section is sleeved with ring gears or fixed gears with the diameters increasing or decreasing in sequence; the ring gears and the fixed gears with the diameters increasing or decreasing in sequence which sleeve the outer side of the gear shifting output shaft I are correspondingly engaged with the fixed gears and the ring gears with the diameters increasing or decreasing in sequence which sleeve the outer side of the gear shifting output shaft II to form variable gear pairs; one end of the gear shifting output shaft I is in transmission connection with the power input shaft through the clutch; and one endof the gear shifting output shaft II is in transmission connection with the power output shaft through an output gear. The gear shifting control operation is simple, and speed changing of more gearsis realized.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a gearbox with an inner support type shift mechanism. Background technique [0002] At present, with the increasingly stringent national requirements for energy-saving standards for automobiles, manufacturers are constantly tapping potentials in gearboxes in addition to improving engine technology. Among them, improving fuel economy by increasing the gear of the gearbox is one of the commonly adopted methods. Regardless of whether it is a manual transmission (MT) or an automatic transmission (AT) car, the gearbox gradually increases from the initial 3-6 forward gears to 7-10 forward gears. With the increase of gears, the volume and weight of the gearbox are also increasing, causing various automobile manufacturers to struggle to find a balance point in the contradiction of energy saving and weight reduction. Especially for transverse engines, due to the very limited space, mu...
