Description
Technical field
The utility model relates to vehicle testing technique field, relates in particular to a kind of with the adjustable reaction type brake tester of clutch coupling wheelbase.
Background technology
Invention disclosed patent 201110066757.7 " a kind of reaction type brake tester and control method thereof ", adopt auxiliary cylinder travel mechanism to control auxiliary cylinder movement in the horizontal direction and regulate the wheelbase between cylinder, solve some problems that fixedly exist because of the distance between cylinder axis during automobile detects, made brake tester meet different kinds of tyre diameter automobile and carry out the demand accurately detecting at same testing table.The problem that this brake tester exists is: master rotor and auxiliary cylinder are connected to one by rotor drive and strainer, two cylinders can rotate with identical speed, and want to make the wheelbase between cylinder to change, between major-minor cylinder, must relatively rotate, between cylinder, just have like this velocity contrast, drum wheelbase just easily regulates; And wheelbase regulate time vehicle tyre be pressed on two cylinders, if produce velocity contrast between cylinder, so just allow a cylinder and wheel produce slides to I haven't seen you for ages, and the friction force that will make cylinder and wheel occur to slide is very large, this force of sliding friction hinders wheelbase and regulates, and this will make wheelbase adjustment process become very difficult.
Summary of the invention
In order to overcome the deficiency of above-mentioned reaction type brake tester, the utility model proposes a kind of with the adjustable reaction type brake tester of clutch coupling wheelbase.
The utility model is realized by following technical measures: construct a kind of with the adjustable reaction type brake tester of clutch coupling wheelbase, comprise control module, left roller assembly, right roller assembly, each roller assembly comprises frame, master rotor, main drum shaft bearing, master rotor drive unit, auxiliary cylinder, auxiliary roller axis bearing, auxiliary cylinder travel mechanism, rotor drive and strainer, wheelbase sensor, sensing cylinder, speed probe, support, position transducer; Master rotor is fixedly supported upon in frame by main drum shaft bearing, and one end of master rotor is connected with the output shaft of master rotor drive unit, and the housing of master rotor drive unit is connected with frame by power sensor; In frame, there is guide rail, auxiliary cylinder is bearing on frame guide rail by auxiliary roller axis bearing, auxiliary cylinder one end is connecting auxiliary cylinder travel mechanism, auxiliary cylinder travel mechanism one end is fixed in frame, the other end is connected with auxiliary roller axis bearing, regulates direction to be connected with wheelbase sensor at auxiliary roller axis bearing wheelbase; Sensing cylinder is installed between master rotor and auxiliary cylinder, and sensing cylinder is by support and spring-loaded in frame, and one end that support is connected with frame is provided with position transducer, and sensing cylinder one end is provided with speed probe; Master rotor and auxiliary cylinder are realized mechanical drive by rotor drive and strainer, and strainer comprises stretcher, stretching pulley, and stretcher one end is fixed in frame, the other end is provided with stretching pulley; It is characterized in that rotor drive comprises clutch coupling, master rotor sprocket wheel, auxiliary cylinder sprocket wheel, stretching pulley, chain, clutch coupling is between cylinder and roller sprocket; Control module and position transducer, wheelbase sensor, speed probe, power sensor, auxiliary cylinder travel mechanism, master rotor drive unit, clutch coupling electrical connection, for the information of pick-up transducers, control master rotor drive unit, auxiliary cylinder travel mechanism, clutch coupling, storage and output detections result.
The utility model is to eliminate like this wheelbase to regulate the problem occurring: will between one of them cylinder and roller sprocket, add clutch coupling, when drum wheelbase is adjusted, control module disconnects clutch coupling, cylinder and roller sprocket disconnect, and master rotor and auxiliary cylinder just no longer connect as one so, and the cylinder that clutch coupling is housed is just no longer subject to the constraint of another drum movement, become free cylinder, while regulating drum wheelbase so again, between major-minor cylinder, just very easily produce relative motion, wheelbase is regulated and become easy.
The beneficial effects of the utility model are: between cylinder and roller sprocket, add after clutch coupling, in the time that drum wheelbase regulates, two cylinders easily produce relative motion, can easily realize the adjusting of testing table drum wheelbase.
