Abstract
The utility model relates to the field of engine performance testing and particularly relates to an automatic transmission engine test tool. A technological flywheel disk for an automatic transmission engine hot test comprises a plurality of axial locking assemblies arranged in a ring array with the axle center of a disk body as the center. An adjusting screw rod is arranged at the axle center of the disk body. An embedded disk is arranged between radial support blocks and the adjusting screw rod. The embedded disk and the adjusting screw rod form a lead screw pair. A contact surface between the embedded disk and the radial support blocks is an inclined surface. When the embedded disk does axial movement along the adjusting screw rod, the radial support blocks are pushed to do radial movement along the adjusting screw rod. A return spring is used for returning the radial support blocks. One end of the return spring takes a positioning bolt vertical to the disk body as a fixing end surface, and the other end of the return spring is contacted with the radial support blocks. The technological flywheel disk is simple in structure and convenient to operate and use; the process of assembly and disassembly costs no more than 30 seconds, production efficiency is greatly improved and labor intensity is mitigated at the same time; and counterweight problems in an engine offline test are effectively solved.

Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 1, an active toothed disk 6 of existing automatic transmission engine is mainly by a middle sheet stamping moulding, thin plate and external toothing welding, before and after middle adopts, clamping plate are strengthened being welded, rise on active toothed disk 6 and be provided with several crescent holes 14, under normal circumstances, crescent hole 14 has 3 and becomes equilateral triangle to be arranged on active toothed disk 6, and playing in addition active toothed disk 6 proximal edge places has some pilot holes 15.Except external toothing is machine-shaping part, all the other are stamping parts and are welded whole assembly, so exist the form accuracy in positional precision, hole of each pitch of holes and the problem such as dimensional accuracy is lower, this has brought certain difficulty to regioselective of frock.Operation conditions while considering engine test, technique Flywheel disc should under any circumstance must tightly touch active toothed disk, no matter axially and radially all must not have at all and become flexible, so having relatively high expectations to technique Flywheel disc;
As shown in Figure 2,3, a kind of automatic transmission engine thermal testing technique Flywheel disc in the utility model, comprise the disk body 12 of technique Flywheel disc, several radial support pieces 4 of annular array centered by the axle center of disk body 12, radial support piece 4 is corresponding with the crescent hole 14 on an active toothed disk 6, radial support piece 4 has propped up active toothed disk 6 by radial force, has avoided active toothed disk 6 to rock; Several axial lock locking assemblies 7 of annular array centered by the axle center of disk body 12, axial lock locking assembly 7 plays active toothed disk 6 with the corresponding locking of pilot hole 15 rising on active toothed disk 6, has avoided active toothed disk 6 to move axially.
The axle center place of described disk body 12 arranges an adjusting screw(rod) 1, adjusting screw(rod) 1 can directly rotate with common outer hexagonal spanner, screw rod 1 role is equivalent to a leading screw, between described radial support piece 4 and described adjusting screw(rod) 1, be provided with embedding dish 2, described embedding dish 2 forms lead screw pair with adjusting screw(rod) 1, surface of contact between embedding dish 2 and radial support piece 4 is inclined-plane, compresses crescent hole 14 when embedding dish 2 promotes back-up block 4 during along adjusting screw(rod) 1 axially-movable along the radial motion of screw rod 1; In order to ensure snap-in force between described radial support piece 4 and an active toothed disk 6, the supporting surface of radial support piece 4 adopts the crescent identical with crescent hole 14 passes;
