Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a gear shifting device. Background Technology

[0002] As a crucial component of modern vehicle transmission systems, the gear shifting mechanism is responsible for transmitting the driver's input to the gearbox via mechanical or electronic means, thereby enabling gear shifting. With the development of the automotive industry, the design of gear shifting mechanisms has undergone several technological iterations, from mechanical to cable-operated, and then to electronically controlled systems. Among these, the mechanical gear shifting mechanism, due to its simple structure and low cost, was widely used in early manual transmission vehicles.

[0003] Cable-operated shifting mechanisms have been widely used in passenger cars, trucks, and some commercial vehicles. However, with the increasing diversification of vehicle types and user needs, some limitations of cable-operated shifting mechanisms have gradually become apparent. For example, the elasticity of the cable itself can lead to a decrease in transmission accuracy, especially in long-distance or complex layouts where signal attenuation, loosening, and wear are common problems. Furthermore, because the cable requires a high degree of linearity in its installation space, cable-operated structures often fail to realize their full potential in confined or complex installation environments.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] refer to Figures 1-2 A gear shifting device, comprising:

[0031] Handle 100 is used to receive user input and control gear shifting operations;

[0032] The longitudinal connecting rod 101 is connected to the handle 100 at one end and to the shift assembly at the other end, which is used to transmit the operation signal of the handle 100.

[0033] The longitudinal connecting sleeve 102 is connected to the middle of the longitudinal connecting rod 101 and is used to stabilize the connecting rod;

[0034] The gear shifting assembly includes a connecting bend 103, a transverse connecting rod a104, a support sleeve 105, a ball sleeve 106, a transverse connecting rod b107, and a gearbox rocker arm 108. The gear shifting assembly is used to complete the precise adjustment and transmission of gears.

[0035] As a further aspect of this utility model, the two ends of the connecting bend 103 in the gear shift assembly are respectively connected to the longitudinal connecting rod 101 and the transverse connecting rod a104. The design of the connecting bend 103 adopts an arc-shaped path, which is mainly used to avoid the limitations of vehicle installation space, thereby flexibly adapting to the complex spatial layout of different vehicle models, while ensuring the smoothness of transmission signals and the flexibility of the path.

[0036] As a further aspect of this utility model, the ball sleeve 106 in the gear engagement assembly is disposed at the connection between the transverse connecting rod a104 and the transverse connecting rod b107. The ball sleeve 106 has a certain degree of freedom of movement and allows the longitudinal connecting rod 101 to be flexibly connected with the transverse connecting rod, thereby adapting to various installation conditions and improving the adaptability and flexibility of the transmission system.

[0037] As a further part of this utility model, the support sleeve 105 in the gear-holding assembly is used to provide support and limit the transverse connecting rod a, support the transverse connecting rod a, prevent it from bending or displacing excessively, and enhance the stability and durability of the system.

[0038] As a further embodiment of this utility model, one end of the gearbox lever 108 is fixedly connected to the transverse connecting rod b107, and the other end is connected to the input end of the gearbox. The gearbox lever 108 is used to receive the motion signal of the connecting bend 103 and realize gear adjustment, accurately transmit the motion signal to the gearbox, realize gear adjustment, and ensure the accuracy and reliability of gearbox operation.

[0039] As a further feature of this invention, a support base 109 is also included. The support base 109 is used to support and limit the transverse connecting rod a104, and ensures the overall operational stability by being installed on the vehicle structure. It supports the transverse connecting rod a104 and provides a limiting function to ensure that the transverse connecting rod a104 is stable and reliable during operation.

[0040] Working Principle: In this application, the handle 100 receives the user's input operation signal and transmits the signal to the gear shifting assembly via the longitudinal connecting rod 101, thereby achieving precise gear adjustment and signal transmission. The pushing and pulling action of the handle 100 drives the longitudinal connecting rod 101 to move. The longitudinal connecting sleeve 102 is installed in the middle of the longitudinal connecting rod 101 to effectively support and stabilize the connecting rod, preventing displacement caused by vibration or external force, and ensuring the smoothness and accuracy of signal transmission. The end of the longitudinal connecting rod 101 is connected to the transverse connecting rod a104 via the connecting bend 103. The connecting bend 103 is designed with an arc path, mainly to avoid the limitations of vehicle installation space, thereby flexibly adapting to the complex spatial layout of different vehicle models, while ensuring the smoothness of signal transmission and path flexibility. Driven by the connecting bend 103, the transverse connecting rod a104 transmits its movement to the inside of the gear shifting assembly. The transverse connecting rod a104 is connected to the transverse connecting rod b107 via a ball sleeve 106. The ball sleeve 106 provides a certain degree of freedom of movement between the two rods, allowing them to adapt to different installation angle requirements and reducing the impact of installation errors on system operation, thus improving the flexibility and adaptability of the gear shifting mechanism. The end of the transverse connecting rod b107 is fixedly connected to the gearbox rocker arm 108, the other end of which is connected to the gearbox input end. This rocker arm receives motion signals from the transverse connecting rod b107 and transmits them to the gearbox to complete gear adjustment, ensuring the accuracy and reliability of gear shifting. Furthermore, the support sleeve 105 provides necessary support and restraint for the transverse connecting rod, preventing excessive bending or displacement due to uneven force or vibration during operation, thereby improving the stability and durability of the gear shifting mechanism. The support seat 109 provides further support and fixation for the transverse connecting rod a104 and, by being installed on the vehicle structure, ensures the operational stability of the entire gear shifting system, effectively reducing the risk of swaying or dislocation even under high vibration or complex operating conditions. Through the synergistic effect of the above components, this gear-shifting mechanism not only achieves accurate transmission of operating signals, but also solves the installation problem of traditional pull-wire gear-shifting systems in complex spatial layouts through the avoidance design of the connecting bend 103, thereby significantly improving the adaptability, stability and reliability of the gear-shifting mechanism.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
