Novel airplane push rod type handbrake mechanism

Abstract

The invention discloses a novel airplane push rod type handbrake mechanism, including a bearing box, A bearing box is provide with a cavity, fixing platesare fixed on the opposite side wall in the cavity, The fixing plates are provided with rear brake shoes, the bottom of the cavity is provided with a sliding groove, the sliding block is installed in the sliding groove, the upper end of the sliding block is fixed with a support block, the rear brake shoe is fixed on one end side wall of the support block, and a hand brake cable is fixed on the other end side wall of the support block. The invention improves the push rod type handbrake mechanism of the airplane, the angle between the handbrake cable and the body floor is reduced when the handbrake cable moves forward and backward, Further, the arrangement occupying space of the hand brake cable is reduced, the space is enlarged, the production cost is reduced, the function of convenient replacement of the hand brake cable is realized,the stability is improved, the installation and disassembly are convenient, the failure caused by not replacing the hand brake cable in time is avoided, the operation is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of hand brakes, in particular to a novel aircraft push rod type hand brake mechanism. Background technique [0002] The professional name of the handbrake is the auxiliary brake, which is different from the principle of the brake. It uses a steel wire to connect to the rear brake shoe to brake the car. Long-term use of the handbrake will cause plastic deformation of the steel wire. Since this deformation is irreversible, long-term use will reduce the effectiveness and increase the stroke of the handbrake. There is also a return spring used with the handbrake. When the handbrake is pulled up, the spring is stretched; when the handbrake is released, the spring returns to its original length. When the handbrake is used for a long time, the spring will also deform accordingly. After using it to a certain extent, the car must be inspected or replaced according to the relevant procedures to ensure the normal use ...

Problems solved by technology

[0003] With the development of the national economy, different types of cars appear in people's field of vision, and cars have become a very important means of transportation in people's lives. Among the various mechanisms in the car, the handbrake structure has become an indispensable part of the production of cars. Part of it, however, the angle between the existing aircraft push rod type handbrake cable and the body floor is too large when it moves back and forth, left and right, because the handbrake cable layout generally requires a curvature radius of 120mm, resulting in too much space for the cable layout, and poor stability, which cannot be continuous If it is used for a long time, it is easy to break down. Therefore, we have proposed a new type of aircraft push-rod handbrake mechanism to solve the above problems
