Bulldozer operation control device and bulldozer manipulation adjustment method

Abstract

The invention belongs to the technical field of bulldozers, and discloses a bulldozer operation control device and a bulldozer operation adjustment method. The bulldozer operation control device comprises an operation connecting rod mechanism, wherein the two ends of a first connecting rod are rotationally connected to a clutch pedal and a first rocker arm respectively; the two ends of a second connecting rod are rotationally connected to the first rocker arm and a second rocker arm correspondingly; the end, away from the second connecting rod, of the second rocker arm is rotationally connected to a control valve of a main clutch, so that the main clutch is switched between a combined state and a separated state; the two ends of a third connecting rod are rotationally connected to the first rocker arm and a gearbox gear locking mechanism correspondingly, so that the gearbox gear locking mechanism is switched between a gear shifting state and a gear locking state; and the two ends of a fourth connecting rod are rotationally connected to the second rocker arm and an inertia brake correspondingly, so that the inertia brake is switched between an enclasping state and a loosening state. According to the bulldozer operation control device, the clutch pedal is used for controlling the main clutch, the inertia brake and the gearbox gear locking mechanism at the same time.

Description

technical field [0001] The invention relates to the technical field of bulldozers, in particular to a bulldozer manipulation control device and a bulldozer manipulation adjustment method. Background technique [0002] As a special shoveling and transporting machinery, mechanical bulldozers are mainly used for farmland reconstruction, fish pond operations, water conservancy construction, urban facilities and road construction and other operations. [0003] The existing bulldozer manipulation control device mainly has the following two forms: [0004] The first type, the traditional bulldozer control device includes a main clutch and a handle, the driver operates the handle to control the main clutch, the main clutch is located between the engine and the gearbox, and is used to cut off the power transmission between the engine and the transmission system to To achieve the purpose of shifting and reversing. Although the traditional mechanical transmission method has the advan...

AI Technical Summary

Problems solved by technology

Although the traditional mechanical transmission method has the advantages of high transmission efficiency, fuel saving and easy maintenance, but the manual control and manipulation is used to realize the mechanical lever compression of the main clutch, which has poor controllability, easy fatigue of the driver, and poor experience.

[0005]Second, the new type of bulldozer control device includes clutch pedal, main clutch, inertial brake, transmission lock mechanism and control link mechanism, the driver steps on the clutch pedal , respectively control the hydraulic valve of the main clutch, the inertial brake and the gearbox locking mechanism by operating the linkage mechanism, but due to the complex structure of the manipulation linkage mechanism, it is difficult to realize the simultaneous control of the hydraulic valve, inertial brake and gearbox locking mechanism. control

If the hydraulic valve control adjustment of the main clutch is not in place, the pressure of the main clutch cannot meet the requirements, resulting in the failure of the main clutch to work normally

If the control adjustment of the inertial brake is too tight, it is easy to cause early wear of the friction plate and affect the service life

If the inertia brake control adjustment is too loose, there is a problem of difficulty in shifting gears

If the gearbox locking mechanism is not adjusted properly, the gear will not be engaged or the gear will be disengaged during driving, which will affect the safety of the normal driving of the bulldozer
