Abstract
The invention discloses a shifting fork with a tension spring sleeved with balance balls. The shifting fork comprises a shifting fork handle base, shifting fork arms and a stretching damping balance spring device. An installing hole is formed in the center of the shifting fork handle base. The shifting fork arms are arranged at the two ends of the shifting fork handle base. Shifting fork feet are installed at the bottoms of the shifting fork arms. The two ends of the stretching damping balance spring device are fixedly connected to the shifting fork arms. A stretching damping balance spring body comprises stretching spring bodies and a string bead rod. The stretching spring bodies are installed at the two ends of the string bead rod. The string bead rod is sleeved with the multiple balls. By means of the mode, the stretching damping ability of a shifting fork body can be improved, the situation that due to excessive stress, the shifting fork body is cracked in the using process is avoided, the service life of the shifting fork body is prolonged, the steel balls stringed on the stretching damping balance spring device can have the effect of balancing the shifting fork, and the shifting fork body can work more stably.
Description
Technical field
The present invention relates to shift fork field, particularly relate to the shift fork that a kind of band is inserted in balance ball draught spring.
Background technique
Shift fork in machinery is mainly used for stirring shifting slide gear, changes its position on gear shaft, can move up and down or move left and right, thus realize different speed.Or the control of clutch in engineering goods, such as end face is in conjunction with the structure of tooth, and the structure of interior external tooth, all needs to realize combining and being separated by its part of fork controls.Also having a kind of be the control of electrical equipment in engineering goods is also need shift fork to realize the closed of switch and to disconnect, and is generally that in electrical appliance kit, card power switch is touched on each one of both sides, stirs, thus realize the running of lathe different direction about shift fork or up and down.But some control structures firm being difficult to stirs; or shift fork weares and teares comparatively serious in Long-Time Service process; not very laborsaving when making sometimes to stir; lack corresponding protection when being subject to larger stress and break; and traditional shift fork does not possess the device of buffering stress to protect shift fork body, shift fork is reduced working life.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the shift fork that a kind of band is inserted in balance ball draught spring, both the stretching cushioning ability of shift fork body can be improved, again by stretching damping balance spring device is gone here and there cover steel column play balance shift fork effect, this physical efficiency of shift fork is worked more stably.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of band to be inserted in the shift fork of balance ball draught spring, comprise shift fork handle set, shift fork arm and stretching damping balance spring device, described shift fork handle set central authorities offer mounting hole, described shift fork arm is located at described shift fork handle set two ends, install bottom described shift fork arm and be provided with shift fork fork pin, described stretching damping balance spring device two ends are connected and fixed on described shift fork arm, described stretching damping balance spring body comprises extension spring body and beading bar, described extension spring body is installed and is located at described beading bar two ends, on described beading bar, cover has multiple ball body.
In a preferred embodiment of the present invention, described extension spring body one end is fixed on described shift fork arm arm face by screw, and the described extension spring body the other end is connected and fixed described beading bar, and described beading bar two ends all symmetrical installation are provided with described extension spring body.
In a preferred embodiment of the present invention, described stretching damping balance spring device lateral level is installed and is arranged between described shift fork arm.
In a preferred embodiment of the present invention, described ball body connecting length is less than described beading pole length.
In a preferred embodiment of the present invention, described ball body is single solid steel cylinder.
In a preferred embodiment of the present invention, described shift fork handle set and described shift fork arm, described shift fork are pitched pin and are integral type and cast linkage structure.
The invention has the beneficial effects as follows: the present invention both can improve the stretching cushioning ability of shift fork body, the situation that in avoiding shift fork body to use, stress excessively bursts apart, extend shift fork body working life, again by stretching damping balance spring device is gone here and there cover steel column play balance shift fork effect, this physical efficiency of shift fork is worked more stably.
