High elastic automobile steering gear dust cover

Abstract

The invention relates to a high-elasticity dust cover for an automobile steering device. The high-elasticity dust cover is characterized by comprising the following components in parts by weight: 25-35 parts of chlorinated rubber, 10-20 parts of butadiene rubber, 5-15 parts of nylon fiber, 4-6 parts of tetramethylsilane, 4-6 parts of polyester fiber, 1.5-3 parts of boron fiber, 4-6 parts of straw fiber, 3-5 parts of palm oil, 1.5-3 parts of cowhide powder, 4- 6 parts of carbon fiber, 1-2 parts of steel fiber, 2-4 parts of guar gum, 4-6 parts of asbestos powder, 4-6 parts of sepiolite fiber, 3-5 parts of nano-silica, 1.5-2.5 parts of an antiager, 1-2 parts of aluminum silicate fiber, 1.5-2 parts of ceramic fibers, 3-5 parts of straw ash, 2-3 parts of dimethicone, 1.5-2 parts of chloroplatinic acid, 1-3 parts of vaseline and 2-4 parts of ceramic fiber cotton. According to the high-elasticity dust cover disclosed by the invention, the traditional rubber material is added with carbon fiber, steel fiber, ceramic fiber cotton and other fiber raw materials, so that the elasticity of the dust cover is greatly enhanced, the breakage and deformation phenomena do not occur in the long-term work, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a highly elastic automobile steering gear dust cover. Background technique [0002] Automobile steering gear is an important part of the car. It drives the gear rack in the steering gear to move left and right through the steering wheel of the steering gear, and the rack drives the steering wheel to swing to complete the steering. In order to ensure the normal use of the steering gear, prevent The internal gear and rack of the steering gear are corroded and stuck. Generally, a dust cover is installed between the left and right tie rods and the rack at both ends of the steering gear, and the two ends of the dust cover are clamped and fixed with clamps. On the tie rod and the rack, the dust covers at both ends are alternately compressed and stretched when the car turns, the air in the dust cover on the compressed side cannot be discharged, and the air in the dust cover on the st...

[0002] Automobile steering gear is an important part of the car. It drives the gear rack in the steering gear to move left and right through the steering wheel of the steering gear, and the rack drives the steering wheel to swing to complete the steering. In order to ensure the normal use of the steering gear, prevent The internal gear and rack of the steering gear are corroded and stuck. Generally, a dust cover is installed between the left and right tie rods and the rack at both ends of the steering gear, and the two ends of the dust cover are clamped and fixed with clamps. On the tie rod and the rack, the dust covers at both ends are alternately compressed and stretched when the car turns, the air in the dust cover on the compressed side cannot be discharged, and the air in the dust cover on the stretched side cannot Therefore, the alternating compression and stretching not only make the dust cover prone to deformation and fracture and lose its protective function, but also the air damping phenomenon generated by the alternating compression and stretching increases the steering torque, which leads to an increase in the resistance of the steering operation and reduces the driving force. comfort
