Problems solved by technology

The above two solutions have disadvantages: the dual-engine configuration scheme has high fuel consumption and high emissions, and the installation of dual-engines takes up a lot of space for special vehicles, and this configuration generally has the phenomenon of large horses and small cars
The shortcomings of the above patents are that the road sweeper with dual engine configuration is bulky and clumsy, with high fuel consumption and high emissions
The shortcomings of the above patents are low transmission efficiency and high fuel consumption of hydraulic transmission
[0007] 3. In the third stage of operation, the ratio of hydraulic power flow to mechanical power flow is constantly changing, and the total transmission efficiency after convergence is unstable;
[0008] 4. The operation method of this scheme is complicated and difficult to master, which is not common to the general

Abstract

The invention relates to a mechanical-hydraulic composite transmission mechanism, consisting of an engine, a transmission, a planetary gear box, a variable displacement hydraulic pump, a hydraulic motor and a reduction gearbox, wherein, the engine is orderly connected with and drives the transmission and the planetary gear box; a planetary gear mechanism of the planetary gear box distributes the power transmitted by the engine to respectively transmit the variable displacement hydraulic pump and a center wheel; the variable displacement hydraulic pump is orderly connected with and drives the hydraulic motor and a half shaft; the half shaft gathering a mechanical power flow transmitted by the center wheel and a hydraulic power flow transmitted by the hydraulic motor extends out of the planetary gear box to output power; the half shaft is connected with and drives the reduction gearbox and then drives a rear axle to drive an automobile to run. The special automobile refitted with the technology of the invention is a single engine configuration, continuously variable running can be achieved with a mechanical-hydraulic composite transmission mode, meantime, a vehicle device is driven to work with a mechanical transmission mode; a mechanical transmission mode can be converted for fast running, a dynamic system occupies small vehicle space, has a low emission, a high transmission efficiency and a low oil consumption.

Description

technical field [0001] The invention relates to a transmission mechanism, in particular to a mechanical-hydraulic compound transmission mechanism. Background technique [0002] Many engineering operations need to use the chassis of the car to carry the operating equipment while driving and perform various construction operations, such as road sweepers and harvesters. The power transmission of some of the operating devices is realized by an engine through a mechanical transfer case to simultaneously drive the vehicle and the operating device to work, such as the transmission mechanism of the harvester. However, since road sweepers and other operating devices need to constantly change the driving speed during driving, and the engine speed is changed during variable speed driving, the quality of work will be reduced. Therefore, road sweepers and other operating devices cannot use this power transmission method. [0003] At present, there are two solutions for the power transmi...
