Embodiment Construction

[0021] figure 1 Shown is a schematic diagram of the structure of the C-shaped track body. The rubber track 1 is made of rubber material, and the C-shaped gear slot 2 is made of engineering plastics. The two parts are formed by two-color injection molding process.

[0022] When the C-shaped track body is working with the shifting actuator, friction will be generated between the actuator acting on the external force; because the damping between the plastic and the rubber is large, most of the mechanical energy is converted into internal energy and consumed, effectively The noise caused by the instantaneous impact force generated by mechanical energy and the mechanism damage caused by vibration inside the mechanism are avoided. At the same time, the C-shaped structure can realize the sound wave attenuation after multiple reflections of the sound radiation inside, and the sound wave propagating into the cab will not be recognized by the human ear.

Abstract

The invention discloses a sound-absorbing large-damping self-resetting track mechanism, which adopts a C-shaped track body. The track body is injected with a two-color injection mold. The inside of the track body is inlaid with rubber materials. Dry friction occurs between the rail bodies. The bullet bears the extrusion force of the gear slot, and the internal spring is compressed accordingly. The extruded spring has the function of storing energy. When the external force is removed, the spring returns to its original state, and the whole mechanism is reset at the same time. The present invention adopts a structure with large damping to help reduce the resonance amplitude of the structure, and avoid mechanism damage caused by the vibration stress inside the structure; it helps the mechanism to quickly recover to a stable state after being subjected to an instantaneous impact; Acoustic radiation from mechanical vibrations. The present invention also realizes the shift form of the internal mechanism of the gear shifter, which is self-resetting. This mechanism is realized by the principle that the spring deforms under the action of the external force and returns to its original shape after the external force is removed.

Description

technical field [0001] The invention relates to an automobile shifter, in particular to a sound-absorbing large-damping self-resetting track mechanism in the automobile shifter. Background technique [0002] With the development of the automobile industry, people have put forward higher and higher requirements for the functions and performance of automobiles, especially the safety and handling comfort. [0003] The control feeling of the car directly affects the driver's driving experience, and the superior driving control feeling can reduce the driver's fatigue during driving. As a leader in the traditional industry, the automotive industry pays more and more attention to the driver's experience in addition to the overall performance of the car. When consumers buy a car, they pay more and more attention to the overall handling experience of the car. [0004] The electronic shifter retains the external shape structure of the traditional shifter, saves the mechanical connec...
