Speed changer of vortex cloud rod engine

Abstract

A speed changer of a vortex cloud rod engine belongs to the mechanical field and is mainly used for saloon car engines and cargo truck engines. The technical problems that in the existing speed changer design scheme and part manufacture, assembly and maintenance are complicated, manufacture cost is high, oil consumption and temperature rise are difficult to control, environmental protection is influenced, volume is large, weight is heavy, the requirements of design on lightweight saloon cars and low oil consumption can not be met, and engine energy is consumed, part abrasion is increased and gear shift operation is slow in response speed and long in response time when a neutral gear runs at a high speed and the like are really solved. The newly-designed technical scheme is that a gear disc is in elastic and soft connection with a shaft, a screw rod controls a shaft core mechanism to perform sensitive quick on-gear and off-gear operations, a clutch is not required to switch off when acceleration time is 4s100km / h in operation, and the neutral gear is not required to idle. Bidirectional gear-selecting and gear-shafting operations can be flexibly performed, and the effect of a seven-gear double-clutch speed changer can be replaced. The speed changer of the vortex cloud rod engine is small in volume, light in weight and very stable in performance, and electronic full-automatic control is easily achieved.

Description

technical field [0001] The invention belongs to the field of mechanical design and manufacture. It is suitable for multi-gear transmissions of engines of locomotives, automobiles, and cars. Background technique [0002] The design scheme of the engine transmission for the same series of locomotives is complicated, which complicates the manufacture of parts, overall assembly, use and maintenance, and the manufacturing cost is high, and the fuel consumption and temperature rise are difficult to control, which is unfavorable to environmental protection. The engine transmission is large in size and heavy in weight, which brings much inconvenience to the car design and low fuel consumption; the more unfavorable aspect of the existing various types of transmissions is that the gears that are not in gear are all idling at different speeds, waiting for the shift fork to move at any time. Gear selection and shifting, these behaviors increase the wear of gear teeth, consume engine en...

[0002] The design scheme of the engine transmission for the same series of locomotives is complicated, which complicates the manufacture of parts, overall assembly, use and maintenance, and the manufacturing cost is high, and the fuel consumption and temperature rise are difficult to control, which is unfavorable to environmental protection. The engine transmission is large in size and heavy in weight, which brings much inconvenience to the car design and low fuel consumption; the more unfavorable aspect of the existing various types of transmissions is that the gears that are not in gear are all idling at different speeds, waiting for the shift fork to move at any time. Gear selection and shifting, these behaviors increase the wear of gear teeth, consume engine energy and other unfavorable factors are particularly prominent; and the common method of shifting gears is a fork, which has a large control force, unstable control performance, easy wear, and easy deformation.
