Benefits of technology

This new design makes sure there's no trouble with attaching wheels onto vehicles by removing them from their hubs without having any tools attached themselves. Its technical effect will improve its ease-of-use for testing purposes while improving overall productivity.

Problems solved by technology

Technological Problem: After testing an automobile's engines by measuring their outputs with a special device called a dynameter or other instrumentation, there may also require removal of wheels attached to them during maintenance procedures due to difficulty separating these components. Existing tools have limitations such as requiring excessive effort and being complicated to assemble/disassemble.

Embodiment Construction

[0010] The structure of the present invention will be further described below in conjunction with the accompanying drawings and through embodiments.

[0011] The tool for dismantling the wheel pin of the engine test stand has the following structure: the dismantling tool 1 is a cylinder, the upper end of the cylinder is a hexagonal nut, and the lower end of the cylinder is provided with a through groove. The groove width of the through groove is greater than the thickness of the wheel pin cap 2 by 1mm; the groove depth of the through groove is greater than the height of the wheel pin cap by 1mm; the outer diameter of the removal tool cylinder is smaller than the inner diameter of the pin perforation 4 in the wheel set of the test bench 1mm .

[0012] When it is necessary to dock or disassemble the wheel set in the engine test bench, insert the front end of the removal tool into the pin hole in the wheel set. Then use a wrench to fix the wheel pin, and finally use another wrench

Abstract

The invention discloses a coupling pin disassembling tool of an engine test bed. The dismounting tool is structurally characterized in that a dismounting tool body is provided with a cylinder, a hexagon nut is arranged at the upper end of the cylinder, a through groove is formed in the lower end of the cylinder, the groove width of the through groove is 1mm larger than the thickness of a couplingpin head, the groove depth of the through groove is 1mm larger than the height of the coupling pin head, and the outer diameter of the detachable tool cylinder is 1mm smaller than the inner diameter of a pin penetrating hole in a coupling set of the test bed. According to the disassembling tool, in the disassembling process of the coupling set, the front end of the tool is inlaid into the pin penetrating hole in the coupling set, then the coupling pin is fixed by utilizing a spanner, finally, a nut of a threaded section of the coupling pin is rotated by using another spanner, and assembling ordisassembling can be carried out conveniently at the moment. The disassembling tool has the advantages of being easy to manufacture and very convenient to use, fastening or disassembling can be carried out when the disassembling tool sleeves the head part of the coupling pin, and therefore the problem that the head part of the coupling pin is difficult to fix can be solved, and the assembling efficiency of the test bed can be effectively improved.
