Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of suspension piece maintenance, especially to a dismounting device for suspension piece torsion bar maintenance. BACKGROUND

[0002] Suspension piece torsion bar is an important part of automobile chassis suspension, such as the light passenger car suspension piece torsion bar structure disclosed in the current publication CN211468101U, which comprises two piece rods and a transverse torsion bar. The transverse torsion bar comprises a hollow designed rod head, a rod neck and a rod body. The rod head is arranged at both ends of the transverse torsion bar. The rod body is the middle section of the transverse torsion bar. The rod neck is the transition section connecting the rod head and the rod body. The rod head, the rod neck and the rod body are smoothly connected. The wall thickness relationship between the rod head, the rod neck and the rod body is: the wall thickness of the rod neck > the wall thickness of the rod head > the wall thickness of the rod body. One end of the piece rod is provided with a piece rod shaft hole matched with the rod head. The other end is provided with a ball hinge bushing hole. The upper and lower surfaces of the middle side of the piece rod are symmetrically provided with weight reduction blind holes. The middle side of the piece rod is distributed with a plurality of weight reduction holes. The utility model improves the steering performance of the passenger car. The weight reduction ratio of the piece torsion bar structure reaches 29.61%. The strength and rigidity of the piece torsion bar structure after weight reduction still meet the working requirements.

[0003] The suspension piece torsion bar thereof, as shown in Figure 1 and Figure 2 includes a transverse torsion bar 8 and a piece rod 9 installed at both ends of the transverse torsion bar 8. When in use, the transverse torsion bar 8 and the piece rod 9 of the suspension piece are prone to bending deformation when transmitting power. After deformation, they need to be dismounted, corrected and maintained before they can be used. However, the existing dismounting is mostly manual dismounting of the piece rod 9 from both ends of the transverse torsion bar 8. Due to deformation, manual dismounting is very inefficient and time-consuming and labor-intensive.

[0004] Therefore, it is necessary to provide a new dismounting device for suspension piece torsion bar maintenance to solve the above technical problems. UTILITY MODEL CONTENTS

An electric push rod one is embedded on the support plate. A circular push plate is fixedly installed on the extension end of the electric push rod one and faces the outer side of the support plate.

[0008] The second electric push rod is fixedly installed on the side wall of the support plate, and a pressing and clamping assembly is fixedly installed on the telescopic end of the second electric push rod.
