Embodiment Construction
[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] The steering gear parts need to use the elastic load in the testing process, and the steering gear elastic load can be combined with other test devices to complete the overall test of the steering gear. The elastic load of the steering gear in the prior art can only achieve a certain amount of elastic load loading. If it is necessary to load the steering gear with a different value, the entire elastic load of the steering gear nee...

The invention discloses an elastic load of a steering engine. The elastic load comprises a load rod sleeved with a spring; two ends of the spring are connected with a right spring seat and a left spring seat respectively, and the load rod is provided with an adjusting bush used for abutting against the right spring seat; an adjusting nut is arranged at one end of the right spring seat and located on the adjusting bush, and the position of the spring can be adjusted; and a first square groove used for containing a steel ball is formed in the end, located on the left spring seat, of the load rod, and a baffle used for abutting against the steel ball is arranged on the load rod. When the load rod moves towards the adjusting nut, the load rod pushes the left spring seat connected with the load rod to compress the spring, so that the spring is pressed to generate thrust, and the adjusting bush is pushed to be separated from the load rod. When the load rod moves back to the adjusting nut, the load rod drives the adjusting bushing to push the right spring seat to compress the spring, so that the spring is pressed to generate pulling force. By replacing different springs, a steering engine can be loaded with different values; and by arranging the steel ball, the load rod can be prevented from rotating circumferentially, and only linear motion of the load rod is guaranteed.
Description
technical field [0001] The present invention relates to the technical field of steering gear, in particular to a steering gear elastic load. Background technique [0002] The steering gear parts need to use the elastic load in the testing process, and the steering gear elastic load can be combined with other test devices to complete the overall test of the steering gear. The elastic load of the steering gear in the prior art can only realize a certain amount of loading on the steering gear. If it is necessary to load a different value on the steering gear, the entire elastic load of the steering gear needs to be replaced, resulting in redundant mechanisms and processing The quantity is large, the cost is high, and it cannot be applied to the needs of various steering gear tests. [0003] Aiming at the problem in the prior art that it is necessary to load the steering gear with different values, the elastic load of the entire steering gear needs to be completely replaced, re...
