Embodiment Construction

[0023] like figure 1 , figure 2 , image 3 As shown, a new type of hybrid transmission system used in wheeled excavators is composed of tires, rims, rear drive axle A14, rear drive shaft A13, lower joint gearbox A1, driving hydraulic motor C, and front drive shaft A11 , front drive axle A12, intermediate transmission shaft B4, upper transmission case B3, main transmission case B2, diesel engine B1, radiator B11, transverse transmission shaft C11, hydraulic pump C1, characterized in that,

[0024] The right side of the lower combined gearbox A1 is taken as the front side, and the left side of the lower combined gearbox A1 is taken as the rear side;

[0025] The driving hydraulic motor C is installed on the front side of the lower combined gearbox A1, and the driving hydraulic motor C can drive the operation of the lower combined gearbox A1;

[0026] The first output shaft in the middle of the front side of the lower combined gearbox A1 is connected to drive the operation of...

Abstract

The invention relates to a novel hybrid transmission system for a wheel-type excavator. When in a working state, a main speed changing box is automatically switched to a neutral position, a diesel engine drives a hydraulic pump to run by virtue of a transverse transmission shaft, the hydraulic pump controls a driving hydraulic motor to rotate, then the driving hydraulic motor drives a lower linkedspeed changing box to act; when in a pavement driving state, the lower linked speed changing box is separated from the driving hydraulic motor by virtue of a clutch, the diesel engine drives the mainspeed changing box, and the transmission output of the main speed changing box drives the action of the lower linked speed changing box successively by virtue of an upper transmission box and an intermediate transmission shaft; the lower linked speed changing box respectively drives a front transmission shaft and a rear transmission shaft by virtue of an output shaft I and an output shaft II to respectively transfer torque to a front drive axle and a rear drive axle; and the drive axles drive a wheel rim and a tire to rotate, and a front-rear drive purpose can be finally achieved. The novel hybrid transmission system for the wheel-type excavator has the characteristics of novel structure, more reasonability in allocation and application of machine power, energy conservation, consumption reduction, high driving speed, and high working efficiency.

Description

technical field [0001] The invention relates to a novel hybrid transmission system applied to a wheeled excavator. Background technique [0002] At present, wheeled excavators generally use a fully hydraulic drive hydraulic motor to drive the whole machine. This drive method will have problems such as low torque, high energy consumption, slow driving speed, and low work efficiency due to insufficient driving force. Contents of the invention [0003] In order to solve the above problems, the present invention provides a new type of hybrid transmission system applied to wheel excavators, which has the characteristics of novel structure, more reasonable distribution and use of machine power, energy saving and consumption reduction, fast driving speed and high working efficiency. [0004] In order to achieve the above object, the present invention provides the following specific technical measures: a novel hybrid transmission system applied to wheeled excavators, which is comp...
