Description

Technical Field

[0001] The present invention relates to the technical field of vehicle power devices, and particularly to an engine throttle auxiliary control mechanism. Background Art

[0002] With the development of society, special vehicles are used more and more widely. Under driving or parking conditions, the power of the chassis vehicle engine is utilized to add special functions to the vehicle. The chassis vehicle throttle mechanism is a mechanism for controlling the engine speed. The free control of the engine speed is a prerequisite for the driving safety and reliability of the vehicle. However, existing special vehicles often connect a spring to the original chassis vehicle throttle mechanism, which causes an increase in spring resistance during the gear shifting of the chassis vehicle, changes the force state of this mechanism of the original vehicle, reduces the flexibility of the mechanism operation, and increases the driving risk. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an engine throttle auxiliary control mechanism that is simple in structure, easy to process and manufacture, easy to implement, and can improve the driving safety and reliability of the vehicle.

[0004] The present invention is realized through the following technical solutions:

[0005] An engine throttle auxiliary control mechanism includes a push rod and a rocker arm. The rocker arm includes a rocker handle and a long chute. The long chute is fixedly arranged at the end of the rocker handle. The middle part of the rocker handle is installed on the motor shaft of the vehicle motor. Both ends of the push rod are installed with spherical plain bearings. One end of the push rod is connected to the vehicle throttle control mechanism through a spherical plain bearing, and the other end is slidably installed in the long chute through the pin shaft of the spherical plain bearing.

[0006] Optimally, the tail of the rocker handle is in a thickened dovetail shape, and an installation hole with a keyway is opened at the centroid of the rocker arm. The rocker arm is installed on the motor shaft through a key connection at the installation hole.

[0007] Advantages of the Present Invention

[0008] The engine throttle auxiliary control mechanism provided by the present invention uses a push rod and rocker arm connection mechanism to replace the spring mechanism. On the one hand, it reduces the resistance of the original engine throttle mechanism operation and improves the flexibility of the mechanism operation. On the other hand, it reduces the elastic deformation during use and greatly improves the operation stability of the engine throttle control mechanism. Description of the Drawings

[0014] An engine throttle auxiliary control mechanism includes a push rod 3 and a rocker arm 4. The rocker arm includes a rocking handle 7 and a long chute 6. The long chute is fixedly arranged at the end of the rocking handle, and the two can be integrally formed, which is convenient for manufacturing, processing and installation, and enhances the stability of the overall structure.

[0015] The middle of the rocking handle is installed on the motor shaft of the vehicle motor 5. Joint bearings 2 are installed at both ends of the push rod. A threaded hole is provided at the end of the push rod, and an external thread is provided at the end of the joint bearing. The two are connected by thread fitting, which is convenient for disassembly and assembly. One end of the push rod is connected to the vehicle throttle control mechanism 1 through the pin shaft of the joint bearing, and the other end is slidably installed in the long chute through the pin shaft of the joint bearing.

[0016] Specifically, the tail of the rocking handle can be designed as a thickened dovetail shape. The thickened dovetail part can make the rocker arm have static balance characteristics, while the long chute part is relatively thin, which can reduce the overall mass of the rocker arm, reduce the moment of inertia of the rocker arm, and reduce the starting torque of the motor. At the same time, the length of the long chute is long enough to ensure that the rocker arm does not swing with the vehicle chassis engine throttle control mechanism at any position, reduce its movement resistance, and enhance its operation flexibility.

[0017] Secondly, a mounting hole 8 with a keyway is opened at the centroid of the rocker arm. The centroid of the rocker arm is at the center of the mounting hole for installing the motor, so that the rocker arm can stop at any angle. In addition, the rocker arm is installed on the motor shaft through key connection at the mounting hole. The installation of the rocker arm is relatively convenient, and the operation is stable and reliable.

[0018] An engine throttle auxiliary control mechanism provided by the present invention uses a push rod and rocker arm connection mechanism to replace the spring mechanism. On the one hand, it reduces the resistance of the original engine throttle mechanism during operation and improves the operation flexibility of the mechanism. On the other hand, it reduces the elastic deformation during use and greatly improves the operation stability of the engine throttle control mechanism.

[0019] In summary, an engine throttle auxiliary control mechanism provided by the present invention has a simple structure, is convenient for processing and manufacturing, is easy to implement, and can improve the safety and reliability of vehicle driving.

[0020] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
