Description

Technical Field

[0001] The utility model belongs to the technical field of steering of new energy vehicles, and in particular relates to a tie rod for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source (or use conventional automotive fuels and adopt new onboard power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. [1] New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. The steering tie rod is an important part of the vehicle steering mechanism, which directly affects the stability of vehicle handling, the safety of operation, and the service life of the tires. The steering tie rod is divided into two categories, namely the steering tie rod and the steering tie rod. The steering tie rod is responsible for transmitting the movement of the steering rocker arm to the steering knuckle arm; the steering tie rod is the bottom edge of the steering trapezoidal mechanism and is a key component to ensure the correct movement relationship between the left and right steering wheels.

[0003] The existing tie rods for new energy vehicles are generally used in conjunction with the tie rods through a ball head assembly. However, the ball head assembly is very afraid of bumps and collisions. When the ball head assembly is damaged by bumps and collisions, it needs to be replaced in time. However, the ball head assembly and the tie rods are generally fixed by welding, which makes it more troublesome to replace the ball head assembly and requires the use of cutting tools. For this reason, we propose a tie rod for new energy vehicles. Utility Model Content
