Problems solved by technology

Due to the large influence of the thread processing accuracy and the locking torque of the outer snap ring, the threaded connection thrust rod structure often has quality problems such as thread slippage, thread loosening and thread breakage, and its torsion resistance and tensile resistance are low; while welding The thrust rod structure is also prone to weak welding due to the limitation of welding materials and domestic welding technology level, and the product quality stability is poor

Embodiment Construction

[0020] The structure and manufacturing process for implementing the present invention will be described below in conjunction with the accompanying drawings. The present invention is an automobile thrust rod ball head and bushing assembly, which includes a thrust rod ball head 2 and a bushing 3, and a ball joint 1 and a retaining ring assembly 4 are installed on the ball head 2, and is characterized in that the thrust rod ball head 2 and the bushing 3 are connected in a corrugated shape, and the main assembly process includes: 1. Process the connecting part 5 of the thrust rod ball and the bushing into a corrugated shape; 2. Process the connecting part 6 of the bushing and the thrust rod ball Form a matching thin-walled sleeve, and the connection between the sleeve and the ball head of the thrust rod is an interference fit; fix the special riveting tooling on the upper and lower plates of the hydraulic press; 3. Set the pressure parameters of the hydraulic press according to req...

Abstract

A thrust ball head-sleeve pipe assemblage for car is composed of a ball head of thrust rod and a sleeve pipe, which are coupled in corrugated mode. Its assembling technology includes such steps as corrugating the coupled part of said ball head of thrust rod, machining the coupled part of sleeve pipe to become thin wall, setting up the pressing parameters of hydraulic press, setting up the heating power and time of MF heater, heating the thin-wall part of sleeve pipe, inserting it in a dedicated riveting apparatus, turning on hydraulic press to rivet the sleeve pipe with the ball head of thrust rod, and cooling.

Description

Technical field: [0001] The invention relates to an automobile component and an assembly process, in particular to an automobile thrust rod ball head and sleeve assembly and an assembly process. It is mainly used in the process of assembling the ball head of the thrust rod and the bushing into components of the automobile. Background technique: [0002] Automotive thrust rods are widely used in luxury passenger cars and trucks equipped with air suspension and double-axle or multi-axle balanced suspension. The thrust rod of the car is used to keep the position of the axle relatively fixed, and transmit the longitudinal force and lateral force of the car. One end of the product is connected to the axle, and the other end is connected to the frame, which can moderate and suppress the vibration and impact caused by the uneven road surface, ensuring the comfort of the passengers and the integrity of the cargo; in addition to transmitting the longitudinal force and lateral force ...
