Embodiment Construction
[0039] The present invention will be further described through specific embodiments below in conjunction with the accompanying drawings.
[0040] figure 1 It is a schematic diagram of the structure of the six-advance four-inverted fixed-axis transmission mechanism and the gearbox, and describes the fixed-axis transmission mechanism.
[0041] The transmission mechanism of the present invention consists of seven fixed shafts, and can realize six forward gears, four reverse gears, and neutral gear functions. The first fixed shaft I is the input shaft, the second fixed shaft II, the third fixed shaft III, the fourth fixed shaft IV, the fifth fixed shaft V, the sixth fixed shaft VI, and the reverse gear shaft R, the above six fixed shafts are all installed There are gears and clutches, and different gear positions are realized through the combination or disconnection of the gears and clutches that mesh with each other. The sixth fixed shaft VI is the output shaft.

The invention discloses a six-forward-gear four-reverse-gear fixed shaft transmission mechanism of a hinged dump truck and a transmission box thereof. A first fixed shaft I is an input shaft. A sixthfixed shaft VI is an output shaft. During a forward gear, the rotation direction of the first fixed shaft I is in accordance with the rotation directions of a third fixed shaft III, a fourth fixed shaft IV and a sixth fixed shaft VI, and is opposite to the rotation directions of a second fixed shaft II, a fifth fixed shaft V and a reverse shaft R. The reverse shaft R is used for converting the rotation direction to realize the function that the rotation direction of the output shaft and the rotation direction of the input shaft are opposite. During reverse gear, the rotating direction of the first fixed shaft I is in accordance with the rotation directions of the second fixed shaft II and the fifth fixed shaft, and is opposite to the rotation directions of the reverse shaft R, the third fixed shaft III and the fifth fixed shaft V. The fourth fixed shaft IV is only in idling while in reverse gear, and does not take part in gear function. According to the six-forward-gear four-reverse-gear fixed shaft transmission mechanism of the hinged dump truck and the transmission box thereof, six forward gears, four reverse gears and a neutral gear are achieved, and a power output and force taking opening with the front and back directions is formed. The force taking opening is connected with the input end of a torque converter. The transmission box outputs power at the same rotating speedas an engine regardless of the gear position of the transmission box.
Description
technical field [0001] The invention is applied to the field of gearboxes, and in particular relates to a six-inverted four-inverted fixed-axis transmission mechanism of an articulated dump truck and a gearbox thereof. Background technique [0002] The gearbox is a mechanism used to change the speed and torque from the engine. It can change the transmission ratio of the output shaft and the input shaft in stages to meet the driver's control requirements for vehicle speed regulation under different road surfaces and load conditions. The speed change mechanism is the core component of the gearbox. It usually consists of different gears with different meshing relationships, so as to realize different input and output speed ratio relationships, and realize the forward, reverse or neutral gear of the vehicle. [0003] At present, the gearbox commonly used in articulated dump trucks is a coaxial hydraulic mechanical automatic gearbox, which is characterized in that the input shaft...
