Axle lower support convenient for positioning and butt joint

Abstract

The invention discloses an axle lower support convenient for positioning and butt joint, which comprises a plate spring lower seat, a through hole and a connecting pin, wherein push-down brackets are arranged on the two sides of the bottom of the plate spring lower seat; furthermore, the plate spring lower seat is used for carrying out butt joint support on an axle; the through hole is formed in the middle of the inner side of the push-down bracket; a reinforcing plate is arranged in the through hole; a threaded hole is formed in the middle of the reinforcing plate; and one end of the connecting pin is connected into the threaded hole in a penetrating manner. According to the axle lower support convenient to position and butt joint, an axle is supported and reinforced through supporting blocks symmetrically distributed on the inner side of the plate spring lower seat; furthermore, the axle is buffered through a buffer pad on the surface of the inner side of the plate spring lower seat; the connecting pin at one end of a rotating shaft is driven by an ejector rod to be in threaded connection with the threaded hole in the reinforcing plate; therefore, positioning and butt joint between the axle and the axle lower support are completed; and welding equipment is used in cooperation with welding grooves in the two sides of the inner wall of the plate spring lower seat, so that welding and fixing on the connecting portion of the axle and the plate spring lower seat are completed.

Description

technical field [0001] The invention relates to the technical field of automobile axles, in particular to an undercarriage for easy positioning and docking. Background technique [0002] The automobile axle is connected to the vehicle frame through the suspension, and the wheels are installed at both ends. The role of the axle is to bear the load of the car and maintain the normal driving of the car on the road. During the installation of the automobile axle, the corresponding axle lower support needs to be positioned and installed at the designated position, so that the automobile axle can be assembled and used. The assembly between the automobile axle and the axle lower support is generally completed by welding, so that Ensure the stability of the lower bearing of the axle. [0003] There are many types of under-axle bearings on the market, and there are still certain defects in the docking and installation of under-axle supports: it is difficult to locate and connect be...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a vehicle axle lower support that is convenient for positioning and docking, so as to solve the difficulty in positioning and docking between the vehicle axle lower support and the vehicle axle in the current market proposed by the above-mentioned background technology. The instability of the assembly between the axles and the vibration between the lower support of the axle and the axle lead to poor connection stability
