Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and through specific embodiments.

[0013] In order to reduce the external dimension of the tensioning wheel assembly and facilitate the installation of the wheel train belt, the present invention designs a latch structure in the form of a hook on the tensioning arm. The specific implementation is: the tensioning wheel assembly is composed of a pulley 1, a mounting base 2, a tensioning arm 3 and a latch 4, wherein the installation structure of the pulley 1, the mounting base 2, and the tensioning arm 3 is the same as that of the present The technology is the same, there are mounting holes 22, 23 at the two ends of the mounting base 2, which are used to install the assembly on the engine. The improvement of the present invention is that a bolt hole 21 is designed on the installation base 2, and a bolt hook 31 is designed on the tension arm, and a torsion spring 5 is instal...

Abstract

The invention provides a tension pulley assembly with a hook-bolt structure. The tension pulley assembly comprises a belt wheel, a mounting base and a tension arm, wherein the belt wheel is arranged on the mounting base by the tension arm. The tension pulley assembly is characterized in that: a bolt hole is formed on the mounting base; the bolt is inserted into the bolt hole; a hook is arranged on the tension arm; a torsion spring is arranged between the mounting base and the tension arm; and the tension arm reversely rotates under the action of the torsional force of the torsion spring to hook the bolt by the hook. The tension pulley structure provided by the invention can effectively shorten the length of the tension arm so as to reduce the volume of the tension pulley assembly.

Description

technical field [0001] The invention belongs to the technology of the engine wheel train system, and specifically relates to a tension wheel structure. Background technique [0002] With the speed of automobiles becoming higher and the weight of the car body becoming lighter, the problem of vibration and noise is becoming more and more serious, and people's requirements for vibration and noise are becoming more and more stringent. After the car is used for a period of time, the belt tension decays, which is the main reason for the abnormal sound of the accessory belt. Since the fixed tensioning structure cannot compensate for part manufacturing tolerances and the extension of the belt during use, it is gradually replaced by an automatic tensioning structure in the design of the tensioning structure of the front-end belt. The automatic tensioner can effectively solve the above problems, but most of them are bulky, and the installation process is complicated, and the maneuver...
