Summary of the invention
The utility model has solved the speed changer that prior art exists and has been handled by stiff rod, can produce vibration and noise and pass to operator cabin, and the poor problem of travelling comfort during driving provides a kind of and driven comfortable and do not have to vibrate and the gear shift switching mechanism of noise.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: a kind of gear shift switching mechanism, it is characterized in that described switching mechanism comprises mounting bracket, on this mounting bracket, flexibly connect shift selecting rocking arm, this shift selecting rocking arm flexibly connects gear shifting rocking arm, and this gear shifting rocking arm is connected and fixed support by connecting rod mechanism.Described mounting bracket is a stepped shaft, on first order trapezoidal faces, be provided with gear selecting flexible axle fixed hole, be provided with gear shift flexible axle fixed hole on the trapezoidal faces of the second level, two described fixed holes are arranged on heteropleural, and the junction surface between described mounting bracket second level trapezoidal faces and the third level trapezoidal faces is the inclined-plane.Fixed hole on the first order trapezoidal faces is used for installing the gear selecting flexible axle, and the fixed hole on the trapezoidal faces of the second level is used for installing the gear shift flexible axle, and is provided with several fixed holes on the side of third level trapezoidal faces, is used for fixing to connect gearbox.The speed changer that stiff rod can be handled is realized the flexible axle manipulation like this, has improved the travelling comfort of driving, and has eliminated vibration and the noise that passes in the operator cabin.
As preferably, described shift selecting rocking arm is the L type, and this shift selecting rocking arm is movably connected on the mounting bracket by connecting sheet.The described shift selecting rocking arm the other end flexibly connects gear shifting rocking arm by the spin body, and this spin body is located in the U type connecting body.This shift selecting rocking arm can rotate around the immovable point with connecting sheet, by the spin body on it and the cooperation of gear shifting rocking arm, realizes the gear selecting of several gears.
As preferably, described connecting rod mechanism comprises the bulb connecting rod of two flexible connections, and one of them bulb connecting rod one end connects gear shifting rocking arm by connecting cover, and an end of another bulb connecting rod flexibly connects fixed support.This fixed support is provided with two fixed holes, fixes with fixed hole to be connected on the gearbox, and the bulb connecting rod rotates like this, promotes to connect cover and moves, can be so that gear shifting rocking arm is realized each gear.
The utility model is skillfully constructed, and the speed changer of hardening lever operation is that flexible axle is handled, and has improved the travelling comfort of driving, and has eliminated the vibration and the noise that pass in the operator cabin.
Description of drawings
Fig. 1 is a kind of perspective view of the present utility model:
Fig. 2 is that the A of Fig. 1 is to structural representation;
Fig. 3 is that the B of Fig. 1 is to structural representation.
Embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described further.
Embodiment 1.See Fig. 1, Fig. 2 and Fig. 3, this routine a kind of gear shift switching mechanism, this switching mechanism comprises mounting bracket 4, flexibly connects shift selecting rocking arm 5 on this mounting bracket 4, this shift selecting rocking arm 5 flexibly connects gear shifting rocking arm 3, and this gear shifting rocking arm 3 is connected and fixed support 6 by connecting rod mechanism.Described mounting bracket 4 is a stepped shaft, on first order trapezoidal faces, be provided with gear selecting flexible axle fixed hole 8, this gear selecting flexible axle fixed hole 8 is used for installing the gear selecting flexible axle, be fixed on this gear selecting flexible axle fixed hole 8 by gear selecting flexible axle mount pin 1, on the trapezoidal faces of the second level, be provided with gear shift flexible axle fixed hole 9, this gear shift flexible axle fixed hole 9 is used for installing the gear shift flexible axle, be fixed on this gear shift flexible axle fixed hole 9 by gear shift flexible axle mount pin 2, two described fixed holes are arranged on heteropleural, and the junction surface between described mounting bracket 4 second level trapezoidal faces and the third level trapezoidal faces is the inclined-plane, be provided with some attachment holes 7 on the side of third level trapezoidal faces, mounting bracket 4 is connected (as shown in Figure 1) by this attachment hole 7 with gearbox.
Wherein, described shift selecting rocking arm 5 is the L type, and this shift selecting rocking arm 5 is movably connected on the mounting bracket 4 by connecting sheet 13.Described shift selecting rocking arm 5 the other ends flexibly connect gear shifting rocking arm 3 by spin body 14, and this spin body 14 is located in the U type connecting body 15.When flexible axle promotes downwards, shift selecting rocking arm 5 rotates around immovable point, shift selecting rocking arm 5 other ends are swung to the right, by the nylon spin body 14 on the shift selecting rocking arm 5 and the cooperation of gear shifting rocking arm 3, promote gear shifting rocking arm 3 around the transmission shift lever assembly towards clockwise rotating, finish 1,2 gear selectings, otherwise finish 5, reverse gear, when flexible axle does not promote up and down, be to put (as shown in Figure 3) at 3,4 gears.
In addition, described connecting rod mechanism comprises the bulb connecting rod 12 of two flexible connections, one of them bulb connecting rod 12 1 end connects gear shifting rocking arm 3 by connecting cover 11, one end of another bulb connecting rod 12 flexibly connects fixed support 6, fixed support 6 sides are provided with plurality of fixed bracket holes 10, are used for connecting gearbox; This connects cover 11 and connects the transmission shift lever assembly, when flexible axle promotes gear shifting rocking arm 3 to the right, because fixed support 6 has been fixed the motion of bulb connecting rod 12, be that gear shifting rocking arm 3 can only rotate around an end of bulb connecting rod 12, having promoted the transmission shift lever assembly simultaneously moves right, according to the difference of shift selecting rocking arm 5 gear selecting positions, can hang into 1,3,5 grade of three gear when gear shifting rocking arm 3 promotes to the right, otherwise hang 2,4, three gears of reverse gear (as shown in Figure 2).
