Description

A kind of automobile variable speed operating control

The utility model relates to self-propelled vehicle speed change engage a gear operating controls such as a kind of automobile, belongs to automobile variable speed manipulation technology field.

The speed change engage a gear operating control of self-propelled vehiclees such as automobile is positioned at operator's compartment, change speed gear box then is positioned on the outer car body of operator's compartment, adopt many between operating control and the change speed gear box and socket bar bonded assembly structure control mode one by one, the operating control of this version is too much owing to socketing the bar relay, the gap cumulative errors are big, gear shift displacement delay of response in use often appears, easily lose rank during displacement, phenomenons such as random shelves, especially when gear down, the gearshift time is long, the speed of a motor vehicle descends, gearshift after-acceleration length consuming time, particularly in service running into bypassed the immediate leadership when robbing gear down on the abrupt slope, because the gearshift displacement lags behind, tend to occur the problem that speed change net difficulty or gear are subject to brinelling even beat tooth, for this reason, need existing gear controller is transformed, proposition can overcome the new speed change maneuver control device of above-mentioned defective.

The purpose of this utility model is to provide a kind of reacts synchronously, gear shift accurately puts in place and automobile variable speed operating control simple and compact for structure, easy for installation.

The purpose of this utility model is achieved in that

A kind of automobile variable speed operating control, it comprises bearing support, joystick, speed change seat, speed change driving lever, its improvements are: it also comprises two gear shift lines 5, and the formation of each parts and annexation are:

The speed change seat is fixed on the bearing support, and an end of joystick is spherical termination, and spherical termination is arranged in the spherical seat hole of speed change seat;

Joystick is provided with two support arms, and a support arm links to each other with a gear shift line, and the spherical termination of another support arm is connected with the spherical pore of speed change driving lever one end, the other end of speed change driving lever and another gear shift wire joint;

The speed change driving lever is positioned at speed change seat one side, and the bolster of speed change driving lever is loaded in the speed change seat;

The core of gear shift line is that steel wire rope 16, steel wire rope add sheath 17, and pipe link 7 is established at the steel wire rope two ends, and pipe link is installed in the cutting ferrule 8.

Said apparatus, described pipe link has wiring ring 12.

Said apparatus, described pipe link has Hooke's coupling 18.

Said apparatus is equipped with dust protecting cap 15 on the described pipe link.

The utility model replaces step connection bar in the former gearshift with the gear shift line, the existing gear controller displacement disadvantages such as random shelves, bump gear that lag behind, are easy to lose rank have been solved, through test, when rotating speed changes suddenly with load, can between each gear, switch quickly and easily, when the abrupt slope conversion is low-grade, eliminated the brinelling of gear, had easy to operately, be quick on the draw, gear shift advantage accurately.In addition, that the utility model also has is simple and compact for structure, use advantage reliable, easy for installation, suits to use on various self-propelled vehiclees such as automobile

Below in conjunction with accompanying drawing the utility model being done a nearly step describes in detail.

Fig. 8 is that the K of Fig. 7 is to view.

See also Fig. 1,2,3,4,5, among the figure, the spherical termination of joystick 2 is seated in the spherical seat hole of speed change seat 3, the spherical termination of the support arm 19 of control lever is arranged in the spherical pore of speed change driving lever 4, bolster 6 swivel bearings of speed change driving lever are in the horizontal shaft hole of speed change seat, horizontal shaft hole one end has the beam barrel that stretches out, and torsion spring 9 is housed on the beam barrel, and an end of torsion spring leans against on the block 10 of beam barrel below, the other end leans against on the bearing pin 11 on the speed change driving lever; On the support arm 13 of control lever and the speed change driving lever connecting bore is arranged, the wiring ring 12 of gear shift line one end or Hooke's coupling 18 can be connected with connecting bore by bearing pin, the other end of gear shift line can detour behind each position, chassis and to be connected with engage a gear mechanism in the change speed gear box, wiring ring or Hooke's coupling are threaded with pipe link, sheath 17 adopts rubber tube, the two ends of pipe are fixed in the cutting ferrule 8, and the annular groove on the cutting ferrule is used for cutting ferrule is fixed on back plate 1 or change speed gear box; Pipe link 7 can slippage in cutting ferrule 8, and the push-and-pull stroke of gear shift line steel wire rope 16 can reach 100 millimeters; Back plate 1 shape approximation inverted "L" shaped shape, the horizontal plate face of inverted "L" shaped and the dual-side of vertical plate face make progress backrush, form a vertical seamed edge, be used to strengthen the structural rigidity of back plate: can install dust boot additional on the back plate, telescopic dust protecting cap 15 is housed on the pipe link of gear shift line and change speed gear box coupling end.

See also Fig. 6, among the figure, joystick support arm 13 has three actuated position, and three actuated position are respectively the middle speed position of solid line signal among the figure and the forward and backward gear of long and two-short dash line signal is put.

See also Fig. 7,8, among the figure, the evolution of speed change driving lever 4 is when passing to the left or to the right by joystick, the spherical termination of its support arm 19 thereupon motion up or down realize, the position of speed change driving lever has two grades, among Fig. 7, when joystick is in diagram left side long and two-short dash line line position, the spherical termination upward movement of support arm 19, the coupling end of speed change driving lever and gear shift line moves downward, otherwise, when joystick was in long and two-short dash line position, diagram the right, the spherical termination of support arm 19 moved downward, the coupling end upward movement of speed change driving lever and gear shift line.
