Problems solved by technology

Using the clutch for steering has the following problems: first, it is impossible to realize the in-situ center steering; second, the speed inside the bulldozer is reduced by the friction between the friction plates of the clutch during the steering process, and the power loss is relatively large
In recent years, there has been a differential steering method using hydraulic motors. Although this steering method solves the friction loss during the steering process and can realize in-situ center steering, this steering method requires multiple planetary rows. Not only does the structure compare It is complicated, and the gears and bearings in the planetary row are difficult to lubricate, so this steering method is only suitable for low-speed working conditions, and cannot meet the requirements of high-speed working conditions

Embodiment Construction

[0010] Such as figure 1 As shown, the composite transmission mechanism of the present invention includes a box body 15, and two shaft holes are processed on the left and right box walls of the box body 15, wherein a left side shaft 4 is respectively arranged in a pair of shaft holes corresponding to the left and right box walls. and the right side shaft 21, and the left side shaft 4, the right side shaft 21 and the corresponding shaft holes are rotatably matched by bearings. The outer end of the left side shaft 4 links to each other with the left side transmission 3 of bulldozer, the outer end of the right side shaft 21 links to each other with the right side transmission 22, the left side transmission 3 links to each other with the left wheel 301, and the right side transmission 22 links to each other with the right wheel 2201. A support is provided in the casing 15 between the left side shaft 4 and the right side shaft 21, and a central shaft 10 is arranged on the support, a...

Abstract

The invention discloses a compound transmission mechanism. The compound transmission mechanism comprises two planet rows. Tooth rings of the two planet rows are fixed at two ends of an intermediate shaft respectively in a back-to-back mode, two planet carriers are fixed on a left side shaft and a right side shaft respectively, and a first gear and a second gear are processed on a left sun wheel and a right sun wheel respectively in a conjoined mode and are respectively meshed with a third gear and a fourth gear which are fixed on a zero shaft. The zero shaft is provided with a fifth gear, and the fifth gear is meshed with a sixth gear positioned on a second input shaft. A crawler type bulldozer adopting the compound transmission mechanism can achieve on-site center steering, power loss is small, the high-speed working condition requirements can be met, and the compound transmission mechanism is suitable for a crawler type bulldozer transmission system.

Description

technical field [0001] The invention relates to a mechanical transmission mechanism. Specifically, it is the compound transmission mechanism in the transmission system of crawler bulldozers. Background technique [0002] It is well known in the bulldozer manufacturing industry that most crawler bulldozers use clutches for steering. The use of clutches for steering has the following problems: one is that the in-situ center steering cannot be realized; the other is that the speed inside the bulldozer is reduced by the friction between the friction plates of the clutch during the steering process, and the power loss is relatively large. In recent years, there has been a differential steering method using hydraulic motors. Although this steering method solves the friction loss in the steering process and can realize in-situ center steering, this steering method requires multiple planetary rows. Not only does the structure compare It is complicated, and the gears and bearings i...
