Abstract
The utility model discloses a motor vehicle engine belt tension apparatus. The utility model is mainly characterized in that the base (3) of the stationary contact wheel (1) is hinged with the bracket (4) of a tensioning contact wheel (2) through a rotating connecting shaft (5), and a plannar spiral spring (6) is arranged at the hinged position where is between the base (3) of the stationary contact wheel and the bracket (4) of the tensioning contact wheel; the stationary contact wheel (1) after hinging and the plane of the tensioning contact wheel (2) are on the same horizontal plane. Because the utility model makes the stationary contact wheel installed on the base and the tensioning contact wheel hinge together through the rotating connecting shaft, the two wheels are made to position on the same horizontal plane forever when working; when using, the stationary contact wheel is not needed to install alone without adjusting, and the utility model is convenient for operation. Compared with the prior art, the utility model has the advantage of reasonable and scientific structure; when working, not only the automatic tensioning of the engine belt is maintained but also the positioning error between each wheel train is reduced; the utility model is favorable for the traveling comfort of the engine, reduces the probability that the engine generates abnormal sound, and improves the working effect of the belt tension.
Description
Technical field: the utility model relates to a kind of tension device, what be specifically related to is the improvement invention of dynamo belt tension device on the Motor Vehicle.
Background technique: in the prior art, on the front surface of automotive Diesel engine, each transmission system all has belt pulley, and described belt pulley also passes through many wedges belt connection driving, and many wedges belt must be on the belt pulley of all transmission systems.Because belt is subjected to the effect of predetermined tension, when it was operated, belt stretched a little, so just caused the minimizing of belt tension, thereby made belt slippage, and this can cause excessive noise and wearing and tearing belt.The present motor car engine belt tension contact wheel that uses, its basic working principle has 2 points: the first, the spiral spring in the pretension tensioning contact wheel product; The second, the tensioning contact wheel discharges at work by the moment of the spiral spring of pretension, reaches the purpose of auto-tensioning dynamo belt.Its automatic belt tightener contact wheel and fixedly contact wheel independently install and use respectively, owing to the installation and the foozle of each train can not well be worked two-wheeled and dynamo belt in same reference level, it is not steady thereby motor operation to occur, the time have abnormal sound to produce.
Summary of the invention: in view of the problem of known technology existence, aim to provide a kind of simple in structure, reasonable in design order of the present utility model, make the auto-tensioning contact wheel and fixedly contact wheel at the dynamo belt tension device that remains at after the installation on the same reference level, to satisfy the positioning error of each train operation.In order to achieve the above object, the utility model is finished as follows: this kind motor car engine belt stretcher, include fixedly contact wheel, the tensioning contact wheel, on described fixedly contact wheel, be provided with base, described tensioning contact wheel is provided with support, the support that it is characterized in that the base of described fixedly contact wheel and tensioning contact wheel is hinged by the axle that is rotationally connected, and between the fixedly contact wheel base of described hinge point and tensioning contact wheel support, be provided with plane scroll spring, described after hinged fixedly contact wheel and the plane of tensioning contact wheel on same horizontal plane.Because fixedly contact wheel and tensioning contact wheel that the utility model will be installed on the base are hinged by the axle that is rotationally connected.Two-wheeled work is on the same horizontal plane forever the time, and needn't installs separately when using, need not adjust, be convenient to operation.The utility model compared with prior art has rational in infrastructure, science.On both kept the auto-tensioning of dynamo belt when doing, reduced the positioning error between each train again, and helped the motor traveling comfort and reduced the probability that engine abnormal noise produces, improved the work effect of belt tension.
Description of drawings: the utility model has following accompanying drawing;
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a working state figure of the present utility model.
Embodiment: accompanying drawing has been represented structure of the present utility model and embodiment, further describes the related content and the working principle of embodiment below more in conjunction with the accompanying drawings.Include fixedly contact wheel 1, tensioning contact wheel 2, on described fixedly contact wheel 1, be provided with base 3, described tensioning contact wheel 2 is provided with support 4, the base 3 of described fixedly contact wheel 1 is hinged by the axle 5 that is rotationally connected with the support 4 of tensioning contact wheel 2, and between the fast pulley base 3 of described hinge point and Idle wheel support 4, being provided with plane scroll spring 6, the plane of described fast pulley 1 after hinged and Idle wheel 2 is on same horizontal plane.The elastic force of described plane scroll spring 6 can make the surface tension of tensioning contact wheel 2 control dynamo belts.The utility model when work,, the outer surface of belt on the motor and fixing contact wheel are contacted with the tensioning contact wheel get final product as long as this dynamo belt tension device is installed on the motor.In the running of motor, loosening if belt occurs, the elastic force of the plane scroll spring 6 on the tensioning contact wheel can be adjusted the elasticity of belt voluntarily.The utility model compared with prior art has substantive distinguishing features and progress.
Claims (1)
1, a kind of motor car engine belt stretcher, include fixedly contact wheel (1), tensioning contact wheel (2), on described fixedly contact wheel (1), be provided with base (3), described tensioning contact wheel (2) is provided with support (4), the base (3) that it is characterized in that described fixedly contact wheel (1) is hinged by the axle (5) that is rotationally connected with the support (4) of tensioning contact wheel (2), and between the fixedly contact wheel base (3) of described hinge point and tensioning contact wheel support (4), being provided with plane scroll spring (6), the plane of described fixedly contact wheel (1) after hinged and tensioning contact wheel (2) is on same horizontal plane.
