Abstract

The invention discloses a gearbox and particularly to a multi-gear road surface mechanical gearbox allowing flexible gear shifting. The multi-gear road surface mechanical gearbox allowing the flexible gear shifting comprises an input component, a forward gear component, a reverse gear component, a third gear component and an output component; an elastic coupling is arranged on the input component; the elastic coupling comprises a separable internal tooth ring; the forward gear component comprises a forward gear clutch and a first gear clutch; the reverse gear component comprises a reverse gear clutch and a second gear clutch; the third gear component comprises a third gear clutch; an output gear which is arranged on the output component is meshed with a third gear of the third gear clutch; a check valve is arranged on a rotating oil cylinder; the pressure fluid enters into a working oil chamber through the rotating oil cylinder; a pressure spring is arranged on the rotating oil cylinder. The multi-gear road surface mechanical gearbox allowing the flexible gear shifting has the advantages of being advance and reasonable in structure and high in reliability, achieving continuous impact-free gear shifting and being convenient and comfort to operate.

Description

technical field

[0001] The invention relates to a gearbox, in particular to a multi-gear road mechanical gearbox capable of flexible shifting. Background technique

[0002] In the prior art, a road mechanical vehicle with multiple gears usually uses a mechanical transmission box with a pedal clutch and a multi-gear as a power transmission device. The transmission box of this type of transmission generally has the following problems: one is that when the vehicle shifts gears, it is necessary to manually operate the foot clutch to cut off and combine the power, which increases labor intensity; It is directly related to the experience. The starting process often causes damaging vibrations in the transmission system, resulting in driving shocks and affecting the compaction quality; the third is that the dry friction plates of the pedal clutch are frequently separated and combined, resulting in wear and failure. Contents of the invention
