Description

Automobile steering worm Technical Field The utility model relates to the technical field of worms, in particular to an automobile steering worm. Background In automotive steering systems, the worm is usually referred to as a helical gear used in conjunction with a worm wheel, which together form a worm-worm gear, the function of which in the steering system is to convert an input rotary motion into an output rotary motion, while achieving the purpose of reducing speed and increasing torque, the worm-worm gear having different applications in different types of steering systems, along with the development of the automobile industry, the automobile steering system is increasingly valued in terms of safety, comfort and flexibility, and a worm is used as an important power transmission and steering control element and is widely applied to the automobile steering system, and domestic and foreign scholars and engineers have conducted intensive research and development on the worm to aim at improving the performance and reliability of the worm. The application improves under the prior art, in the prior art, when the automobile steering gear is used for a long time, the pressure intensity at the center of the worm shaft is increased, the worm wheel and the worm are meshed with each other, so that local heating is caused, gluing is easy to occur, if the automobile steering gear is continuously driven at the moment, the gear teeth are easy to deform, the steering hand feeling is affected during driving, even the automobile steering is failed, and accidents occur. The above information disclosed in this background of the application is only for enhancement of understanding of the background of the application and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art. Disclosure of utility model The utility model aims to provide an automobile steering worm so as to solve the problems in the prior art. In order to achieve the purpose, the technical scheme is that the automobile steering worm comprises a first worm, a second worm, a worm gear and a hollow structure, wherein the right side of the first worm is fixedly connected with the worm gear, the hollow structure is arranged on the inner side of the worm gear, and the right side of the worm gear is fixedly connected with the hollow structure. As a further scheme of the utility model, the left side of the first worm is fixedly connected with a mounting block, the left side of the mounting block is fixedly connected with a first connecting block, and the left side of the first connecting block is fixedly connected with a first round block. As a further aspect of the utility model, the mounting block has a length of about 8mm, the first connecting block has a length of about 13mm, and the first round block has a length of about 9mm. As a further scheme of the utility model, the right side of the second worm is fixedly connected with a second connecting block, and the right side of the second connecting block is fixedly connected with a second round block. As a further proposal of the utility model, the length of the second connecting block is about 5mm, and the length of the second round block is about 8mm. The utility model has the following beneficial effects: The utility model discloses a cooperation of first worm, second worm, worm gear and hollow out construction is used, hollow out construction and hydraulic system intercommunication can regard as fluid flow channel, and help transmission turns to the heat that in-process produced, reduces the oil temperature, avoids hydraulic oil overheated and leads to helping hand inefficacy, and hollow out construction's structural design reducible material quantity simultaneously reduces steering system's whole weight to promote the vehicle and control response speed and hang the travelling comfort, especially more obvious in high-speed driving or bend, in addition, hollow out construction's structural design can be used to arrange steering system's hydraulic line, electron pencil or sensor circuit. The automobile steering device is convenient to coaxially connect with components such as a steering shaft and an input shaft, realizes compact mechanical structural design, saves engine cabin space, solves the problems that when an automobile steering device is used for a long time, the pressure intensity at the center of a worm shaft is increased, a worm wheel and a worm are meshed with each other, local heating is caused, gluing is easy to occur, and if the automobile steering device is continuously driven at the moment, gear teeth are easy to deform, steering feel is affected, and even the automobile steering is failed, so that accidents occur.
