Abstract
The utility model relates to a low-speed vehicle automatic belt tensioning mechanism, comprising a bracket and idler wheels, wherein, the idler wheels are connected together through a swinging arm and a support shaft and are arranged on the bracket through a shaft, the shaft is provided with a torsional spring; one end of the torsional spring is limited by a support rod; the other end of the torsional spring is limited by the support shaft; the idler wheels can rotate on the axes of the idler wheels; the swinging arm can swing on the axes of the shaft; the bracket is fixed on a frame; the idler wheels contact the belt. The utility model, which has the characteristics of a reasonable structure and low cost, applies certain pressure to the belt through the torsional spring all the time and can automatically adjust the degree of tightness of the belt.
Description
Technical field:
The utility model relates to a kind of low-speed cars belt automatic tension mechanism.
Background technique:
At present, the connected rear axle that three-wheeled motor car and single cylinder four-wheel low-speed truck are made, the degree of tightness of belt has two kinds of adjustment modes: a kind of is by adjusting motor, another kind is to adjust by track bar, the shortcoming of this dual mode is: adjust time-consuming, it is short to adjust distance, adjusts the untimely belt slippage that causes easily, influences power transmission etc.
Summary of the invention:
The purpose of this utility model provides a kind of low-speed cars belt automatic tension mechanism.
The technical solution of the utility model is to realize like this, comprise support, roller, roller links together by swing arm, support axle, is contained in support by axle again, axle is provided with torsion spring, one end of torsion spring is limited by strut, and the other end of torsion spring is by the restriction of support axle, and described roller can be around self rotational, described swing arm can be swung around axis, support is fixed on the vehicle frame, and roller contacts with belt, gives the certain pressure of belt all the time by torsion spring.
The utlity model has characteristics rational in infrastructure, that cost is low, can adjust the degree of tightness of belt automatically.
Description of drawings:
Fig. 1 is a plan view of the present utility model.
Fig. 2 is a plan view of the present utility model.
Among the figure: 1. support, 2. strut, 3. torsion spring, 4. spool, 5. support axle, 6. swing arm, 7. roller, 8. vehicle frame.
Embodiment:
As shown in Figure 1 and Figure 2, comprise support 1, roller 7, roller 7 links together by swing arm 6, support axle 5, is contained in support 1 by axle 4 again, axle 4 is provided with torsion spring 3, one end of torsion spring 3 is by strut 2 restrictions, and the other end of torsion spring 3 is by 5 restrictions of support axle, and described roller 7 can be around self rotational, described swing arm 6 can be swung around axle 4 axis, support 1 is fixed on the vehicle frame 8, and roller 7 contacts with belt, gives the certain pressure of belt all the time by torsion spring 3.
In three-wheeled motor car or single cylinder four-wheel low-speed truck running process, the roller 7 that swing arm 6 connects is under the effect of torsion spring 3, the surface of roller 7 contacts with belt all the time, when belt is crossed pine swing arm 6 under the effect of torsion spring 3 around support axle 5 counter-clockwise swings, make belt tension, swing arm 6 around support axle 5 swing clockwise, loosens belt under the effect of belt when excessive belt stretch.
