Description
Technical field
The utility model relates to a kind of mechanism for gearbox shifting and stroke detection, belong to wheel box test run technical field.
Background technology
EMT electric shift case shifting shaft mostly is and moves in parallel gear shifting structure, and as shown in Figure 1, require during gearshift that promoting two shifting shafts successively drives shift fork to hang each gear test run, each gear gearshift stroke need reach 11 ± 0.1mm to its outside drawing.Existing test run gearshift mode is for being screwed into corresponding gearshift axle head screw thread place respectively as shown in Figure 2 by two handles, after electric motor starting, drawing handle is linked into four, three, two, one each gear successively and realizes gear shift operation.Because each shelves power of putting into gear of this wheel box reaches 350-400N and without synchronizer structure, therefore can produce pause and transition in rhythm or melody difficult extension phenomenon when hanging each gear, operative employee has strong complaints.
The shortcoming that this process for gear mainly exists is summarized as follows:
A twists shift handle and handle may be caused to come off fall on rotary flange, easily cause personal injury after electric motor starting.Also potential potential safety hazard is there is in shift handle close to output flange.
B respectively keeps off gear shifting force and reaches 350-400N, and direct push-and-pull gearshift is more difficult and can cause the discomfort of hand.
C respectively keeps off gearshift stroke accuracy and reaches 11 ± 0.1mm, and a gear occurred that shift fork and casing were interfered and causes gear not to be suspended to a phenomenon, position as shown in Figure 3 after putting into gear, and cannot to find and existing rhythm of production does not possess the condition that every platform detection one keeps off stroke because of visual.
D gear difficulty is hung and gearshift stroke sampling observation process makes overall test run inefficiency.
Utility model content
The purpose of this utility model is the deficiency overcoming prior art existence, and provides a kind of structure simple, uses easy to operate, reduce accident risk, reduce labour intensity, improve the qualification rate of product, the mechanism for gearbox shifting and stroke detection increased work efficiency.
The purpose of this utility model has been come by following technical solution, described a kind of mechanism for gearbox shifting and stroke detection, it is primarily of gearshift main body and stroke detection parts two parts composition, it is characterized in that described gearshift main body comprise one on the wall box stretching out shifting shaft hard-wired L-type support, this L-type support outer end is hinged with a gear level, and the bottom of gear level is connected to shifting shaft by hinged connecting rod;
Described stroke detection parts comprise the pedestal on a wall box being arranged on shifting shaft limit, outside this pedestal, signal lamp switch are housed and are configured with frizzen.
L-type support described in the utility model is bolted on the sidewall of casing, and described connecting rod is connected with shifting shaft by rotary body parts, and on connecting rod, be fixed with a rotary sleeve; The signal lamp switch plane that the pedestal of stroke detection parts is installed gets minus tolerance with the spacing H of the wall box installing L-type support.
Unthreaded hole connecting rod described in the utility model being fixed rotary sleeve adopts long slot bore, and the end wiring harness interface of described signal lamp switch is combined with signal lamp interface, and described signal lamp switch selects the 3729100-YT that automobile product is conventional.
The utility model can effectively reduce labour intensity during its gearshift, improves test run efficiency; Use simple, can skillfully use after simple teaching; Gearshift detection effect is obvious, can perception 0.02mm stroke change rapidly after debugging, guarantees that a gear reaches the stroke of putting into gear of 11 ± 0.1mm, eliminates loaded down with trivial details hand dipping and to put into gear the step of stroke, and product is shifted gears stroke qualification rate >=99%.The product that dispatched from the factory after this frock of use does not just reflect a gear gearshift incomplete phenomena again, and the factory that returns reducing product leads, provides cost savings.Use of the present utility model substantially increases product test run qualification rate, and actual gearshift and the comparable existing mode of detection efficiency improve about 50%, and economic benefit is very remarkable; There is structure simple, use easy to operate, reduce accident risk, reduce labour intensity, improve the qualification rate of product, the feature such as to increase work efficiency.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 3-4, a kind of mechanism for gearbox shifting and stroke detection described in the utility model, it is primarily of gearshift main body and stroke detection parts two parts composition, described gearshift main body comprise one on the wall box 2 stretching out shifting shaft 1 hard-wired L-type support 3, this L-type support 3 outer end is hinged with a gear level 4, and the bottom of gear level 4 is connected to shifting shaft 1 by hinged connecting rod 5;
Described stroke detection parts comprise the pedestal C on a wall box 2 being arranged on shifting shaft 1 limit, outside this pedestal C, signal lamp switch 6 are housed and are configured with frizzen 7.
Shown in Fig. 4, described L-type support 3 is fixed on the sidewall 2 of casing by bolt 8, and described connecting rod 5 is connected with shifting shaft 1 by a rotary body components A, and on connecting rod 5, be fixed with a rotary sleeve B; Signal lamp switch 6 plane that the pedestal C of stroke detection parts installs gets minus tolerance with the spacing H of the wall box 2 installing L-type support 3.
