Problems solved by technology

Using an automatic tensioner to tension the accessory belt is a better tensioning method, which can ensure the tension of the belt and make the accessory wheel train run reliably, but some wheel trains have small space, which makes it impossible to arrange the automatic tensioner. At the same time, the price of the automatic tensioner is higher, and the cost is higher for engines with small displacement
The belt is tensioned by adjusting the pulley of the accessory wheel system, which is relatively cheap, but it is troublesome to adjust the tension of the belt in the later maintenance. At the same time, when the wrap angle of the pulley of some wheel system accessories is small, it cannot increase the wrap angle of the pulley. effect

Embodiment Construction

[0018] The structure of the present invention is described in detail below in conjunction with accompanying drawing:

[0019] see figure 1 , the tensioning device is composed of a bracket 1, a shaft bolt 2, a nut 3, a pulley 4 and an adjusting bolt 5, wherein:

[0020] For the structure of bracket 1, see figure 2 , the base frame part of the bracket 1 has a bolt hole 13 connected with the engine body, a pulley installation part 14 is arranged on the bracket 1, and a shaft bolt installation plane parallel to the central plane of the accessory wheel train is arranged on the pulley installation part 14, and The two ends of the belt pulley installation part 14 are provided with an adjusting screw installation part bent 90 degrees inward, a waist-shaped groove 11 is arranged on the shaft bolt installation plane, and a U-shaped slot hole 12 is arranged at the lower end. The effect of waist groove 11 is: 1, limited the adjusting range of belt pulley, the range that axle bolt 2 mov...

Abstract

The invention provides an accessory belt tensioning device of an engine accessory wheel system, which comprises a bracket, a pulley, a shaft bolt, a nut and an adjusting bolt; when a screw rod is rotated and adjusted, the pulley moves up and down along the waist-shaped groove of the bracket with the bolt so as to tension or loosen a belt; and simultaneously, after the belt is tensioned, the nut is tightened, the pulley plays the roles of an idler so as to increase the wrapping angle of the adjacent pulley. The tensioning device has the advantages of lower cost, simple and compact structure and convenient assembly, conveniently adjusts the belt, increases the wrapping angle of the pulley, and can achieve the effect of reducing the high cost of a tensioning device of the engine accessory wheel system as well as the adjustment and maintenance difficulty and increasing the wrapping angle of the pulley of the accessory wheel system.

Description

technical field [0001] The invention relates to an automobile engine accessory wheel train system, in particular to a tensioning device for an engine accessory wheel train accessory belt. Background technique [0002] The belt tensioning of the existing engine accessory wheel system generally adopts an automatic tensioner to tension or adjust a certain component pulley in the accessory wheel system to tension the belt. Using an automatic tensioner to tension the accessory belt is a better tensioning method, which can ensure the tension of the belt and make the accessory wheel train run reliably, but some wheel trains have small space, which makes it impossible to arrange the automatic tensioner. At the same time, the price of the automatic tensioner is higher, and the cost is higher for engines with small displacement. The belt is tensioned by adjusting the pulley of the accessory wheel system, which is relatively cheap, but it is troublesome to adjust the tension of the be...
