Description

Technical Field

[0001] The utility model relates to the technical field of loader torque converter assemblies, in particular to a 3-ton loader torque converter connecting seat assembly structure. Background Art

[0002] 3-ton loaders have been widely used and favored by customers for their flexibility and certain tonnage of loading. The torque converter of a 3-ton loader is the core component of the loader's transmission system. The torque converter and gearbox of large-tonnage loaders such as 5-ton and 6-ton loaders generally adopt a dual-variable assembly integrated structure, and support brackets are provided on both sides of the dual-variable assembly to connect with the entire machine frame. Unlike large-tonnage loaders such as 5-ton or 6-ton loaders, the torque converter and gearbox of a 3-ton loader in the prior art generally adopt separate independent assembly components. The front housing of the torque converter is hinged to the engine, and the rear output flange is connected to the drive shaft to transmit power to the gearbox. The overall assembly and fixing method is cantilevered, and the overall force is entirely supported by the cantilever support of the front housing. The defect of the torque converter connector assembly structure is that the front housing of the torque converter is prone to breakage when operating under harsh working conditions. Summary of the invention

[0003] The utility model aims to provide a 3-ton loader torque converter connecting seat assembly which has a simple and compact structure, is easy to assemble and reliable to use, and solves the problem in the prior art that the front housing of the torque converter of the 3-ton loader is easily broken when operating in harsh working conditions.

[0004] To achieve the above purpose, the utility model 3-ton loader torque converter connecting seat assembly includes an upper connecting plate 1, an intermediate transition plate 2 and a lower connecting plate 3, which are welded together and present an "I"-shaped whole; the upper connecting plate 1 is provided with two bolt holes and is assembled and locked with the whole machine frame connecting plate 9 through upper bolts 7, spring washers 6 and nuts 8; two internal threaded holes are provided on the torque converter housing 4, and the lower connecting plate 3 is provided with two bolt holes, and the lower connecting plate 3 is assembled and locked with the torque converter housing 4 through lower bolts 5 and spring washers 6.

[0005] The above-mentioned 3-ton loader torque converter connecting seat assembly is connected and fixed to the whole machine frame by adding a connecting seat assembly on the torque converter, and has the following technical characteristics and beneficial effects:

[0006] 1. The 3-ton loader torque converter assembly adopts a connecting seat assembly between the torque converter housing and the whole machine frame, which changes the existing cantilever assembly method of the torque converter and solves the problem that the front housing is easy to break when the loader is working in harsh working conditions;

[0007] 2. Simple and compact structure, easy assembly and reliable use. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1The utility model is a schematic diagram of the main structure of a torque converter connecting seat assembly of a 3-ton loader.

[0009] Figure 2 The utility model is a left-side structural schematic diagram of a torque converter connecting seat assembly of a 3-ton loader.

[0010] Reference numerals: upper connecting plate 1, middle transition plate 2, lower connecting plate 3, torque converter housing 4, lower bolt 5, spring washer 6, upper bolt 7, nut 8, whole machine frame connecting plate 9. DETAILED DESCRIPTION

[0011] The following is a further detailed description of the 3-ton loader torque converter connector assembly of the utility model in conjunction with the accompanying drawings and specific embodiments.

[0012] Figure 1-Figure 2 As shown, the utility model 3-ton loader torque converter connecting seat assembly includes an upper connecting plate 1, an intermediate transition plate 2 and a lower connecting plate 3, which are welded and form an "I"-shaped whole; the upper connecting plate 1 is provided with two bolt holes and is assembled and locked with the whole machine frame connecting plate 9 through upper bolts 7, spring washers 6 and nuts 8; two internal threaded holes are provided on the torque converter housing 4, and the lower connecting plate 3 is provided with two bolt holes, and the lower connecting plate 3 and the torque converter housing 4 are assembled and locked through lower bolts 5 and spring washers 6; so that the 3-ton loader torque converter assembly is connected between the torque converter housing and the whole machine frame through the connecting seat assembly, which changes the original cantilever support mode and solves the problem that the front housing is easy to break in the prior art.

[0013] The utility model 3-ton loader torque converter connecting seat assembly adds a connection and fixation between the torque converter housing and the whole machine frame, changes the assembly and fixing method of the torque converter in a cantilever state, and solves the problem that the front housing is easy to break when the loader is working under harsh working conditions. In addition, the utility model has a simple and reliable structure, is easy to assemble, and is reliable to use.
