Description
Technical field
The utility model relates to the accessory on a kind of automobile, especially is useful in the push-pull cable flexible axle in gear shift and the gear selecting.
Background technique
Automobile stick control mechanism is distant to the distance between the automobile clutch, be not suitable for directly connecting, because the difference of mounting point and the variation in orientation are not suitable for carrying out transmission with the bindiny mechanism of rigidity, so the drag-line flexible axle uses more and more widely in automobile.
As everyone knows, driver's speed change is handled, and is to swing by all around of manipulator hand lever to realize, this is the reciprocating stroke of both direction, so current push-pull cable control system, will carry the active force of both direction, i.e. thrust and pulling force.The first generation, second generation shift control system that present bus industry is generally used.Exist and make the unsatisfied defective of driver.First generation control system, promptly hard axle adds the control system that cross joint (universal joint) connects transmission, cause the several joints wearing and tearing of stiff rod under the vibration that is in operation because of the deadweight of parts and the effect of brake inertial force, the accumulation of wearing and tearing causes the decline of transmission accuracy, final wrong shelves, disorderly shelves and the abnormal condition such as out of supply of occurring.And the reparation of stiff rod transmission be very the difficulty, in the time of will changing plastic bushings as low-level bus, to remove floor compartment earlier and could operate; And the top of rake tooth coupling all welds, and the transposing easily damaged parts is easier said than done.The push-pull cable control system of two flexible axle transmissions of second generation product, because the load of bearing thrust and two aspects of pulling force during operation, the cable wire flexible axle of long distance is when bearing the 800N thrust, can in conduit, form the waveform bending, increased the friction of rope heart wire rope and conduit greatly, under the flexible axle output terminal situation constant to the confession power of gearbox, then the input end of flexible shaft of manipulator one end will add heavy load more than 50%, when increasing pilot control the physical output, cable wire also can destroy the lay configuration of itself in the bending of thrust, thereby reduces the mechanical property of cable wire; The connection part of cable core and pull bar gathers bending force and shearing force simultaneously, cause the cable core fracture, general cable wire only reaches 100,000 times bearing 180 ° of crooked consequence Load tests, so fatigue damage along with the time of movement accumulation, cause cable core to be easy to fracture, therefore current push-pull cable product can only be guaranteed 200,000 times.Add the increase along with service time, idle stroke also can be along with increase, thereby influences the correctness that speed change is handled.
At present, known automobile drag-line flexible axle be in the middle of for the steel wire mandrel, be fixed with jointing being coated with one deck plastic layer two ends, the ratio of rigidity of this drag-line flexible axle is bigger, costs bigger power in layout when crooked.
Summary of the invention
It is bigger that the utility model has solved in the prior art rigidity of push-and-pull flexible axle, is not easy shortcoming crooked in layout, provides a kind of and can guarantee that enough rigidity is easy to the crooked convenient push-pull cable flexible axle of arranging again.
The utility model has also solved the enough still shortcomings of thrust deficiency of pulling force in the prior art, and a kind of push-pull cable flexible axle that has not enough pulling force to also have enough thrust is provided.
Another purpose of the present utility model is the working life of adopting multiple first structure can effectively improve the push-pull cable flexible axle, and linarity is good, and friction is little.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of push-pull cable flexible axle, comprise mandrel and the exposed axle sleeve of parcel mandrel, wherein, described mandrel is coated with the multiple first of one deck, multiple first also is coated with one deck liner outward, liner is coated with the multiple first flexible pipe of one deck, and multiple first flexible pipe has one deck plastic layer outward, and the two ends of push-pull cable flexible axle are provided with the ball-joint head that connects usefulness.Mandrel can provide gear shift required enough pulling force, and the multiple first of mandrel outer wrapping can provide enough flexibilities, and convenient the installation is provided with liner and can reduces Fu Jia and the friction between the first flexible pipe again between Fu Jia and the multiple first flexible pipe, reduce resistance.
As preferably, described mandrel is made up of the steel wire floor of different winding directions, and multiple first is entwined by flat filament.Described multiple first flexible pipe is wrapped on the liner at interval by steel wire and flat filament, and the part of a circle compresses the part of last circle behind the flat filament.The steel wire of mandrel adopts different winding directions, after curved arrangement, can not produce the internal force of obstruction when bearing different power, can not decrease the power that needs when vowing gear shift, improve efficient, Fu Jia and multiple first flexible pipe adopt flat filament, because the width of flat filament is greater than steel wire, thus the thrust that the thrust that flat filament provides provides greater than steel wire, and also flat filament is folded mutually layer by layer, be gear shift when needing thrust effect better, flat filament can not produce too much slide relative on liner.
As preferably, the winding direction of the flat filament of the multiple first flexible pipe on the multiple first on the described mandrel and the liner is opposite.Different winding directions is extra distortion and the displacement that produces when eliminating push-pull cable flexible axle work after the curved arrangement.
Wherein, the outside of described plastic layer also is with one deck heat insulating tube.Motor can produce a large amount of heat at work, can produce a thermal field around motor, if the appearance of push-pull cable flexible axle is directly exposed outside, therefore outermost plastic layer can need be increased one deck heat insulating tube outside by long roastingization of high temperature.
As preferably, the two ends of described push-pull cable flexible axle are connected with the pull bar of rigidity by the flexible pipe street corner, and rod outer sleeve has guide pipe, and guide pipe is connected with the pull bar of rigidity, be with dirt-proof boot between guide pipe and the pull bar, manage near also being provided with sign on the push-pull cable flexible axle in flexible pipe street corner.Two ends are connected with the pull bar of rigidity and externally are with the effect that guide sleeve can play guiding.
Hose coupling is connected with the end of push-pull cable flexible axle can adopt multiple mode, such as welding, perhaps uses the steel wire tighten, as preferably, described hose coupling be connected by the screw thread riveted joint with the two ends of push-pull cable flexible axle.
As preferably, described ball-joint head is the end that is fixed on pull bar by screw thread.The ball-joint head at two ends is to be used for linking to each other with clutch with the shift control device, and the ball-joint head links to each other the position for spherical with pull bar, can freely rotate, and each is greater than 32.5 ° about the pendulum angle of ball-joint head.
The beneficial effects of the utility model are: the push-pull cable flexible axle adopts multiple first structure crooked easily under the prerequisite that guarantees enough rigidity, the convenient layout installed, gear shift pulling cable will bear two kinds of power of push-and-pull, therefore the inner steel wire mandrel of using, be coated with the existing enough pulling force of multiple first enough thrust can also be provided, and linarity is good, friction is little, output load moment is big, and travel efficiency and load efficiency improve.
