Abstract

The invention discloses a self-tightening automobile tire foreign matter removing apparatus including a bottom board fixedly connected to an automobile body above tires. A cylinder sleeve base is fixed to the middle of a lower end of the bottom board. A cylinder sleeve is fixed to the cylinder sleeve base. The cylinder sleeve is in a hollow structure. An inner flange is arranged on a lower end of the cylinder sleeve. A spring is arranged in the cylinder sleeve. An upper end of the spring is fixedly connected to the cylinder sleeve base. A movable column is fixedly connected to the lower end of the spring. An outer flange is disposed on the top of the movable column and is matched with the inner flange on the lower end of the cylinder sleeve. The movable column is movably clamped inside the cylinder sleeve base. A left clamping member and a right clamping member are respectively disposed at the two sides of the lower end of the movable column, wherein a left hydraulic push rod is fixedly connected horizontally to an outer side of the left clamping member and a right hydraulic push rod is fixedly connected horizontally to an outer side of the right clamping member. A removing arm, equipped with a cleaning wheel, is fixedly connected to the bottom of the movable column. A contact needle is disposed on the middle of the top of the movable column. A contact switch is arranged on the bottom plate, is matched with a contact needle and is electrically connected to an alarm.

Description

technical field [0001] The invention relates to the field of accessories for large-scale trucks, in particular to a self-tightening foreign body remover for automobile tires. Background technique [0002] Most of the rear wheels of large cargo trucks have double tires, and foreign objects are easy to be caught between the tires, which can easily cause tire explosion and flying stones to hurt people. When driving on a muddy road, hard mud is filled between the tires, which will cause the tires to heat up and reduce the braking force, resulting in vicious accidents. There are tire foreign matter alarm devices in the prior art, but these devices only have an alarm function, do not have the function of automatically removing foreign matter, and the structure is relatively complicated; in order to solve these problems, Chinese patent CN2565653Y discloses an automatic removal of foreign matter in double tires of automobiles. , Alarm device, this device comprises the bottom plate ...

Problems solved by technology

[0002] The rear wheels of large freight trucks mostly have double tires, and foreign objects are easily caught between the tires, which may cause tire explosion and flying stones to hurt people

When driving on a muddy road, the tires will be filled with hard mud, which will cause the tires to heat up and reduce the braking force, resulting in serious accidents

There are tire foreign matter alarm devices in the prior art, but these devices only have an alarm function, do not have the function of automatically removing foreign matter, and the structure is relatively complicated; in order to solve these problems, Chinese patent CN2565653Y discloses an automatic removal of foreign matter in double tires of automobiles. , Alarm device, this device comprises the bottom plate that is fixed with the vehicle body above the tire, on the bottom plate is fixed the removal arm bracket, the connecting rod bracket with holes and the switch seat, and the removal arm bracket is hinged with the removal arm. There is a connecting rod with a spring on it and one end is hinged with the end of the removal arm, and the other end is inserted into the hole on the connecting rod bracket, and the end is screwed with a nut. There is a spring-covered contact rod at the end, and a wire is connected to the contact rod; the invention has a simple structure, has dual functions of automatic removal of foreign matter and alarm, complete functions, convenient installation, low cost, and durability, and is suitable for all kinds of large, It is used in medium and small-sized trucks; however, the invention cannot adjust the scraping force of the tire dirt on the removal wall during use, and has poor adaptability to various harsh environments in the natural environment. The response speed of the tire is very slow, which is not conducive to the driver's timely elimination of tire safety hazards
