Problems solved by technology

When the hydraulic system is connected in series with the mechanical system, the stepless speed regulation is completely realized by the hydraulic system. Although the efficiency of this type of system is not good, with the improvement of the manufacturing process of hydraulic components, the transmission efficiency has the potential to be further improved. High power, still achieved certain applications, but poor durability and low reliability

Abstract

The invention provides a speed changing transmission device. An input component, an output component, a hydraulic transmission assembly, a rear planet gear assembly, a front planet gear assembly, a first clutch, a second clutch, a first brake, a second brake and a third brake are included. The output component and the rear planet gear assembly are connected so as to jointly rotate. The front planet gear assembly and the rear planet gear assembly are connected so as to jointly rotate, and the hydraulic transmission assembly and the front planet gear assembly are connected so as to jointly rotate. The first clutch and the second clutch are used for selectively connecting the input component to the front planet gear assembly for joint rotation. The first brake, the second brake, the third brake, the first clutch, the second clutch and a third clutch are selectively combined, and the continuous advancing or retreating transmission ratio between the input component and the output componentis provided. Through clutch and brake switchover and hydraulic system displacement ratio adjustment, switchover can be conducted among hydraulic transmission, hydraulic machine transmission and machine transmission.

Description

technical field [0001] The invention relates to the field of gearboxes or the field of stepless speed regulation of automobiles, in particular to a variable speed transmission device. Background technique [0002] The main function of the transmission is to reduce the speed and increase the torque, and to expand the range of speed and torque, so that the load drive system composed of the engine, transmission and walking system is in the best working state, which is very important for improving the power, fuel economy and production of engineering vehicles. Efficiency is paramount. [0003] The transmission is divided into a stepped transmission and a continuously variable transmission according to the transmission mode. CVTs can be divided into mechanical CVTs, electric CVTs and fluid CVTs according to their operating modes and transmission forms. The advantages of mechanical continuously variable transmissions are mature technology and high efficiency; the disadvantages a...
