The invention discloses a multilevel transmission structure suitable for a press fitting transmission case lining. The multilevel transmission structure comprises an upper pressing plate, a lower pressing plate, multiple transmission pillars and multiple locking pillars, wherein the top ends of the transmission pillars and the locking pillars are fixed on the lower surface of the upper pressing plate; the lower pressing plate is provided with a fixed sleeve used for the locking pillars to pass, the lower pressing plate is slidably connected with the locking pillars through the fixed sleeve, and a first spring is sleeved outside of the locking pillars; one end of the first spring props against the upper pressing plate, the other end of the first spring is fixed in the fixed sleeve, and the outside of the bottom of each transmission pillar is sleeved with a limit sleeve, the top end forms into steps; the limit sleeves are slidably connected with the transmission pillars, and the periphery of the transmission pillars are sleeved with a second spring; and the top end of the second spring is clamped on the steps formed by the top ends of the transmission pillars, and the lower end of the second spring is clamped in the limit sleeves. The multilevel transmission structure provided by the invention has the beneficial effects of being capable of realizing multi-section motion and being suitable for the press fitting transmission case lining, and the structure is simple and practical.
Description
technical field [0001] The invention relates to a transmission structure, in particular to a multi-stage transmission structure suitable for press-fitting gear box bushings. Background technique [0002] The gearbox mainly refers to the gearbox of the car, which is divided into manual and automatic. The manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; It is composed of gear, planetary gear and hydraulic control system, and achieves variable speed and torque through hydraulic transmission and gear combination. The functions are: 1. to change the transmission ratio; 2. to enable the car to run backwards when the rotation direction of the engine remains unchanged; 3. to use the neutral gear to interrupt the power transmission so that the engine can start and idle, and it is convenient for the transmission to shift gears or perform power transmission. output. [0003] It can be seen that...
