Abstract
The invention relates to a shift arm drag, comprising a body, wherein the body is connected with an extension part; a lug boss is arranged on the extension part; the shift arm drag is directly connected with a connecting arm drag of a gear sensor through the lug boss; the connecting arm drag rotates when the shift arm drag drives a shift shaft to rotate. The shift arm drag is simple in structure; the gear change can be more accurately reflected by an integral structure.
Description
Technical field
The present invention relates to a kind of gearshift, specifically, relate to a kind of gearshift torque arm, belong to field of mechanical technique.
Background technique
It is that electronic control unit carries out comprehensive adjustment according to accelerator open degree, Che Du and gear signal etc. that the velocity ratio of automatic transmission case is regulated, therefore stir operating handle the driver and carry out gear while regulating, the gear signal that must the driver be selected by the shift sensing device passes to electronic control unit fast and accurately, so, electronic control unit could be effectively and is carried out exactly the adjusting of gearbox speed ratio, and whether the measurement of shift sensor has accurately determined reliability, the Security of automatic transmission case and the smoothness of controlling.Described shift sensing device comprises gearshift torque arm and shift sensor.
At present, in automatic transmission, the structure of gear shift torque arm commonly used as shown in Figure 1, described gear shift torque arm comprises the body 1 of Z-shaped, body 1 comprises top board 2 and base plate 3, be connected with connecting plate 4 between top board 2 and base plate 3, top board 2 is provided with the gear-shifting inhaul cable mounting hole 5 that can hold gear-shifting inhaul cable, and base plate 3 is provided with the shifting shaft mounting hole 6 that can hold shifting shaft.
Described gear shift torque arm is connected with shift sensor, and when the driver's operation operating handle, operating handle drives gear shift pulling cable, then drives the gear shift torque arm, and the gear shift torque arm drives shift sensor work.
In realizing process of the present invention, the inventor finds in prior art at least to exist following problem, and while adopting gearshift torque arm as shown in Figure 1, described shift sensor can only be selected the separated type shift sensor, the shift signal collection is subject to the impact of surrounding environment, and validity is low.

Embodiment
Embodiment, as shown in Figure 2, a kind of gearshift torque arm, comprise the body 1 of Z-shaped, and body 1 comprises top board 2 and base plate 3, be connected with connecting plate 4 between top board 2 and base plate 3, top board 2 is provided with the gear-shifting inhaul cable mounting hole 5 that can hold gear-shifting inhaul cable, and base plate 3 is provided with the shifting shaft mounting hole 6 that can hold shifting shaft, and base plate 3 is connected with extending portion 7, extending portion 7 is positioned at the side of base plate 3 away from connecting plate 4, and the upper surface of described extending portion 7 is provided with cylindrical boss 8.
As shown in Figure 3, described gearshift torque arm is connected with shifting shaft 9 by shifting shaft mounting hole 6, and boss 8 is connected with and connects torque arm 10, connects torque arm 10 and is connected with shift sensor 11, and shift sensor 11 is fixedly connected with gear box casing by shift sensor support 12.
The gearshift torque arm directly is connected torque arm by boss and is connected with gear position sensor, when gearshift torque arm drive shifting shaft rotates, connect torque arm and rotate thereupon, and simple in structure, integral structure more can accurately reflect gear change.
The above is giving an example of best mode for carrying out the invention, and the part of wherein not addressing in detail is those of ordinary skills' common practise.Protection scope of the present invention is as the criterion with the content of claim, and any equivalent transformation carried out based on technology enlightenment of the present invention, also within protection scope of the present invention.
