A Super Multi-gear Hollow Gear Set Suspension Transmission

Abstract

The present invention relates to the technical field of gearboxes, in particular to a super multi-gear hollow gear set suspension gearbox, which includes a main drive gear set, a fixed gear set, a first shaftless gear set and a second shaftless gear set. The rotation of the main transmission gear set drives the first free gear set of the first shaftless gear set to rotate, and the power transmission is realized through the slidable first shift shaft, and the first shift shaft is slidably arranged inside the fixed shaft , the fixed shaft is connected with a fixed gear set and drives the fixed gear set to rotate, the fixed gear set is meshed with the second free gear set of the second shaftless gear set, and the sliding of the second shift shaft is set at Center position of the second free gear set. The present invention has compact structure and reasonable layout, can achieve 100 shifts without too much change in volume and weight, lower manufacturing cost, can simplify processing and assembly, and facilitate subsequent maintenance operations.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a super multi-gear hollow gear set suspension gearbox. 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 torque converter, planetary gear, hydraulic pitch change system and hydraulic control system, and achieves variable speed and torque through hydraulic transmission and gear combination. [0003] The quality of gearbox performance is the key to measure the power, economy and drivability of construction machinery. The current transmission systems mainly include: mechanical transmission, hydraulic transmission, and hydrostatic transmission. Today, more and more construction machinery is used in gearboxes, and the requirements for high torque...

Problems solved by technology

With the large load and high torque requirements of construction machinery, the structure of the mechanical transmission transmission is becoming more and more complex, with many parts, high precision, difficult processing, complicated maintenance, difficult disassembly, space occupation, and complicated operation.

[0004] Moreover, the existing mechanically driven gearboxes generally have very few shifting gears. Even a large truck with superior performance has only eight to sixteen shifting gears. Large trucks, heavy engineering equipment, etc. , using the gear transmission method, its internal structure is more complicated, there are many parts, the installation accuracy is high, the assembly is cumbersome, the processing cost is high, and the volume is large, and the gears of the transmission are limited.
