Description

Technical Field

[0001] This utility model relates to the field of motor drag testing, specifically to a motor L-shaped bracket support mechanism. Background Technology

[0002] Traditional traction motors use a single-sided suspension structure, therefore, their towing test fixtures are often designed in an L-shape. When using two traction motors mounted on L-shaped brackets for a towing load test, the force characteristics of the single-sided suspension cause the motor to sway left and right at high speeds, resulting in excessive vibration. Excessive vibration can cause the bearing temperature to rise too high, and even damage the bearing, posing a serious safety hazard. Therefore, it is necessary to find ways to increase support points and reduce vibration. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please also refer to Figures 1 to 3 These are the front view, side view, and structural schematic diagram of the L-shaped motor bracket support mechanism provided by this utility model at the foot position.

[0020] The L-shaped motor support mechanism is located between the drag test fixture 1 and the traction motor 2. The L-shaped motor support mechanism includes a jack 3, a support plate 4, and a connecting pin 5.

[0021] The drag test fixture 1 is an L-shaped support, including a horizontally arranged seat plate 11 and a vertically arranged upright plate 12 on the seat plate 11.

[0022] A traction motor 2 is located on the upper right side of the upright plate 12. Two feet 21 are provided on each side of the bottom of the traction motor 2, and machining holes are pre-drilled in the feet 21.

[0023] The jack 3 includes a base plate 31, a cylinder 32, and a piston rod 33 arranged sequentially from bottom to top. The base plate 31 has mounting holes at its four corners, and the piston rod 33 has a threaded hole at its top.

[0024] The towing test fixture 1, traction motor 2, and jack 3 are all existing equipment.

[0025] Two sets of four threaded holes are drilled on the top surface of the base plate 11 directly below the two outermost feet 21. The diameter and relative position of each set of threaded holes are consistent with the four mounting holes of the base plate 31. By setting screws in the mounting holes of the base plate 31 and screwing them down into the threaded holes of the base plate 11 to lock them, the two jacks 3 are vertically fixed to the base plate 11.

[0026] The support plate 4 is a rectangular steel plate with a countersunk mounting hole drilled in the middle and mounting holes drilled at both ends. The diameter of the middle mounting hole matches the threaded hole of the piston rod 33. By installing screws in the mounting holes of the support plate 4 and screwing them downwards into the threaded holes of the piston rod 33 to lock them in place, the support plate 4 is horizontally fixed to the top of the piston rod 33.

[0027] Two connecting pins 5 are inserted into the two outermost feet 21, with a clearance fit. Each end of the connecting pin 5 has two parallel mounting holes along its radial direction. The diameter and spacing of the two mounting holes of the connecting pin 5 are consistent with the mounting holes at both ends of the support plate 4.

[0028] Rotate the connecting pin 5 to a suitable angle to align the mounting holes of both. Insert bolts into the two mounting holes of the connecting pin 5, pass them through the two mounting holes of the support plate 4, and tighten them with nuts at the ends to secure the connecting pin 5 to the support plate 4. Alternately adjust the tightness of the two nuts to ensure even force distribution at both ends of the support plate 4. After tightening the nuts, the foot 32 abuts against the support plate 4, covering the mounting hole in the middle of the support plate 4.

[0029] After installation, the base plate 31, jack 3, support plate 4 and foot 21 are tightened together in sequence. The bolts are only for fixing and do not bear direct force.

[0030] During use, alternately control the two jacks 3 to raise them to a suitable height to ensure that the two feet 21 are evenly stressed, thus supporting the traction motor 2.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
