Embodiment 1

[0041] The new energy vehicle uses a torsion bar spring pre-torsion moment applying device. After the torsion bar spring is quenched and tempered, insert one end of the torsion bar spring into the end sleeve 120 at the end of the output shaft of the stepping motor 2, and then Clamp the torsion bar spring close to the horizontal position, then start the servo motor 4, the servo motor 4 works, drives the screw rod 5 to rotate, and makes the slider 6 move along the rectangular groove 10 to the side of the stepping motor 1 2 until the end sleeve The second 70 is inserted into the other side of the torsion bar spring, and then the servo motor 4 is stopped to work. At this time, the torsion bar spring is clamped, and then the stepping motor one 2 and the stepping motor two 7 are started simultaneously, because the stepping motor one 2 and stepping motor two 7 have the same stepping angle, and the stepping motor one 2 and stepping motor two 7 turn in opposite directions to realize the...

Embodiment 2

[0043] On the basis of Embodiment 1, the following improvements are made: because the servo motor 4 is connected to the bearing end seat 3 by bolts, the output shaft of the servo motor 4 is coaxially connected to one end of the screw rod 5, and the other end of the screw rod 5 One end is connected with the base 1 through a rolling bearing, the slider 6 is slidingly connected with the rectangular groove 10, the lower end of the slider 6 is provided with a threaded hole 60, and the screw mandrel 5 and the threaded hole 60 form a spiral pair connection, the slider 6 The upper end is provided with a cylindrical hole 61, and the stepper motor 2 7 is connected to the slider 6 by bolts, and the output shaft of the stepper motor 2 7 passes through the cylindrical hole 61, so the servo motor 4 can drive the slider 6 along the rectangular groove. 10 movement, changing the distance between end sleeve one 20 and end sleeve two 70, realizing the operation of applying pre-torsion torque to t...

Embodiment 3

[0045] On the basis of Example 1, the following improvements are made: the upper end surface of the base 1 is polished, the slider 6 is a "T"-shaped structure, and both sides of the slider 6 are provided with convex edges 61- 1, and the lower end surface of the convex edge 61-1 has been polished and is in contact with the upper end surface of the base 1, which ensures the stability of the sliding block 6 driven by the screw rod 5 along the rectangular groove 10, thereby ensuring the stability of the end sleeve 120 The coaxiality of the central axis and the central axis of the end sleeve 2 70 ensures the levelness of the torsion bar spring. A scale 12 is provided on the upper end surface of the base 1, and the scale 12 is a steel ruler, which realizes the visual adjustment of the distance between the end sleeve 1 of 20 and the end sleeve 2 of 70. The connecting plate 11 can be welded on the right end face of the base 1, or can be connected by bolts to ensure the stability of th...

Abstract

The invention discloses a pre-torsion moment application device of a torsion rod spring for a new energy automobile. The pre-torsion moment application device of the torsion rod spring for the new energy automobile comprises a base, a first stepping motor, a bearing end base, a servo motor, a lead screw, a sliding block and a second stepping motor. A rectangular groove is formed in the middle of the base. A connecting plate is arranged on the right side of the upper end of the base. The first stepping motor is connected with the connecting plate. The bearing end base is connected with the right end face of the base. The servo motor is connected with the bearing end base. An output shaft of the servo motor is coaxially connected with one end of the lead screw. The other end of the lead screw is connected with the base through a rolling bearing. The sliding block is in sliding connection with the rectangular groove. A threaded hole is formed in the lower end of the sliding block. Screw pair connection is formed by the lead screw and the threaded hole. A cylindrical hole is formed in the upper end of the sliding block. The second stepping motor is connected with the sliding block. A first end sleeve is arranged at the end of an output shaft of the first stepping motor. A second end sleeve is arranged at the end of an output shaft of the second stepping motor. It is realized that pre-torsion moment is applied after the torsion rod spring is subjected to heat treatment. The pre-torsion moment application device of the torsion rod spring for the new energy automobile can be usedfor the torsion rod springs of different lengths, and thereby being high in universality.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, in particular, the invention relates to a pre-torsion moment applying device of a torsion bar spring for a new energy vehicle. Background technique [0002] The torsion bar spring itself is a rod made of spring steel. The torsion bar spring is an elastic torsion bar processed from alloy spring steel. One end is fixed on the frame and the other end is fixed on the suspension. At this time, the bouncing power is transmitted to the torsion bar, and the torsion bar produces torsional elastic deformation. The torsional deformation acts as a buffer, absorbs energy, and ensures the elastic connection between the wheel and the frame. It is suitable for automobiles with independent suspension. [0003] The torsion bar spring is made of alloy spring steel, and its surface is smooth after processing. Although the torsional stiffness of the torsion bar itself is constant, the stiffness of the sus...
