Problems solved by technology

Therefore, the existing pulley mechanism requires extra space for arranging the tension pulley, which is not conducive to the simplified design of the entire mechanism
In addition, after the belt is tensioned, the tensioning pulley is fixed on the installation base, so the belt tension defined by the first pulley, the second pulley and the tensioning pulley cannot be adjusted
In other words, once the belt is tensioned it cannot be adjusted
However, after a certain period of use, the belt will become loose, so that it is necessary to adjust the tension of the belt defined by the first pulley, the second pulley and the tension pulley, and the existing pulley mechanism cannot meet this requirement

Abstract

The invention provides a belt pulley mechanism which is convenient to regulate the tension degree of a belt. The belt pulley mechanism comprises a first belt pulley, a second belt pulley and a belt, and the first belt pulley and the second belt pulley are connected through the belt in a transmission manner, wherein the belt pulley mechanism further comprises a tension bracket fixed on a mounting base. The tension bracket comprises a first sidewall, and an arc guide channel is arranged on the first sidewall; the second belt pulley comprises a mounting rack, the mounting rack is provided with a first fastening hole and a second fastening hole which are parallel to the axial direction of the second belt pulley; the first fastening bolt is used for connecting the second belt pulley to the mounting base through a first fastening hole; and the second fastening bolt can adjustably fix the second belt pulley on the tension bracket through the arc guide channel and a second fastening hole. The invention further provides a power-assisted steering pump assembly. In the belt pulley mechanism disclosed by the invention, the second belt pulley or the second belt pulley has functions of a transmission belt pulley and a tension pulley at the same time, thus the utilization rate of space is improved, and the tension degree can be regulated as required randomly.

Description

technical field [0001] The invention relates to a pulley mechanism and a power steering pump assembly of an automobile. Background technique [0002] In the prior art, the pulley mechanism includes a first pulley, a second pulley and a belt, and the first pulley and the second pulley are connected through a belt transmission. But simply passing the belt around the first pulley and the second pulley usually does not allow the belt to be tensioned and therefore a smooth belt drive cannot be achieved. Therefore, the existing pulley mechanism usually also includes a separate pulley as the tension pulley, and the belt is set around the first pulley, the second pulley and the tension pulley. Belt tensioning can be realized by adjusting the position of the tensioning wheel. Therefore, the existing pulley mechanism needs an extra space for arranging the tension pulley, which is not conducive to the simplified design of the whole mechanism. In addition, after the belt is tensioned...
