Description
Technical field
The utility model provides a kind of chain to regulate tension device, for adjustment and the tensioning of drive chain in automobile braking table, belongs to automobile braking table detection field.
Background technique
The braking force value that drum reaction type automobile braking table records is determined by minimum that in the braking force of vehicle brake, both adhesion between wheel and cylinder.That is, between wheel and cylinder, the size of adhesion decides the braking ability that brake platform to what extent fully can reflect break objectively, and adhesion is larger, reflection truer.Centre distance between the material of cylinder surface and shape, diameter of cylinder, cylinder is the principal element affecting adhesion between cylinder and wheel.Therefore when the material of cylinder surface and shape, diameter of cylinder are fixed, change the centre distance between cylinder into adjustable structure, make detection facility can adapt to different technologies level, different tonnage, different vehicle condition, dissimilar car, there is very large meaning.When centre distance between cylinder changes, the drive chain length between cylinder also changes, and needs chain to regulate tension device.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of chain and regulates tension device, when adjusting centre of the drum's distance, automatically can regulate the length of drive chain, and making drive chain be in tensioning state all the time, avoids the phenomenon of climbing chain, de-chain.
In order to solve the technical problem, the technical solution adopted in the utility model is: a kind of chain regulates tension device, comprise locating oil cylinder, be positioned at above locating oil cylinder with the traversing carriage, 2 the fixed chain wheels seat boards standing on traversing carriage both sides respectively that limit cylinder piston rod and be connected, each fixed chain wheels seat board is equipped with the bar-shaped trough of 1 longitudinal direction, be provided with a tension sprocket that can move up and down in bar-shaped trough in bar-shaped trough, the both sides of tension sprocket are respectively provided with 1 holder chain sprocket wheel; Be provided with the axis of guide between traversing carriage and fixed chain wheels seat board support, one end of the axis of guide is connected with traversing carriage, and the other end is connected with tension sprocket.
Further, the lower end of described traversing carriage is also provided with the tension spring making chain be in tensioning state all the time, and one end traversing carriage of tension spring is connected, and the other end automobile brake machine base is connected.
The beneficial effects of the utility model: chain described in the utility model regulates tension device to comprise the chain length controlling device be made up of fixed chain wheels seat board, tension sprocket and drag chain sprocket wheel, when roll center is apart from change, automatically can regulate the length of drive chain, and prevent from occurring in adjustment process climbing chain or de-chain phenomenon; The limit stoper be made up of locating oil cylinder, traversing carriage and tension spring can make chain in adjustment process be in tensioning state all the time, spacing by locating oil cylinder after adjustment, keeps the stability of drive chain.
