Abstract

The invention discloses an automobile instrument panel transmission cam which comprises a rotating portion, a mounting portion and a connecting portion, wherein the two ends of the rotating portion extend outwards to form the mounting portion and the connecting portion. Multiple cam portions are arranged on the rotating portion in a protruding mode, cross sections are formed in the cam portions, and the cross sections of the cam portions are distributed alternately and parallel to each other. Counter bored holes are formed in the end portion of the mounting portion along the axis, wire outlets are formed in the peripheral surface of the mounting portion, and the wire outlets are communicated with the counter bored holes. The connecting portion is made of steel. The automobile instrument panel transmission cam is simple in structure, good in stability, and excellent in mechanism performance.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and relates to a transmission cam, in particular to an automobile instrument panel transmission cam. Background technique [0002] The car dashboard is a device that reflects the working conditions of the various systems of the vehicle. The common ones are fuel indicator light, washer fluid indicator light, electronic throttle indicator light, and front and rear fog light indicator lights. [0003] Chinese patent CN203686057U discloses a brake camshaft, which includes a cam and a shaft, the front ends of the cam and the shaft are fixedly connected, the center of the shaft and the center of rotation of the cam are on the same straight line, and the outer surface of the end of the shaft is provided with a spline, The cross section of the cam is S-shaped or S-shaped symmetrical, and an arc groove is radially formed on the outer edge of the cam, and a power sensor is fixedly arranged in the arc g...
