Description
Technical field
The utility model relates to the motor vehicle detecting technical field, relates in particular to a kind of single bridge driving machine motor-car chassis dynamometer.
Background technology
Chassis dynamometer is used to detect the motor-vehicle chassis output power, also can be used for the various operating conditions of simulated maneuver vehicle, so that carry out performances of motor vehicles test and technology status judgement.By the cylinder number difference of every side drive wheel correspondence, chassis dynamometer divides single cylinder chassis dynamometer and twin-roll chassis dynamometer two classes, and the former is mainly used in manufacturing plant or scientific research department, and the latter also is widely used in performances of motor vehicles measuring station and maintenance company.Present twin-roll chassis dynamometer twin-roll wheelbase is fixed, mainly have following deficiency: (1) is easy to generate between wheel and the cylinder when adhering to hypodynamic phenomenon, make the on the low side or simulated condition of the power that records inaccurate, accuracy of detection is difficult to guarantee, and is more obvious when especially the wheel load of driving wheel is not enough; (2) surpass certain value when wheel diameter, when making the angle of setting of wheel between cylinder,, need carry out longitudinal register, reduced detection efficiency motor vehicle in order to guarantee that motor vehicle does not seesaw in the testing process less than critical value.
Summary of the invention
In order to overcome the deficiency of existing twin-roll chassis dynamometer, the utility model proposes a kind of single bridge driving machine motor-car chassis dynamometer.
The utility model is realized by following technical measures: construct a kind of single bridge driving machine motor-car chassis dynamometer, comprise that frame, master rotor, auxiliary cylinder, radius of wheel pick-up unit, drum wheelbase detect regulating device, gearing and strainer, charger and measurement and control unit, master rotor is fixedly supported upon on the frame by the main drum shaft bearing, guide rail is arranged on the frame, auxiliary cylinder is bearing in by the auxiliary roller axis bearing on the guide rail of frame, is in transmission connection by gearing and master rotor; The radius of wheel pick-up unit comprises sensing cylinder, support, spring, position transducer, support one end and frame are hinged, the sensing cylinder by support and spring-loaded on frame, spring makes the sensing cylinder closely contact with detected wheel of vehicle, position transducer is contained between support and the frame, be used for measuring the position of sensing cylinder, reflect detected wheel of vehicle radius size with respect to master rotor; For the rotating speed that detects the sensing cylinder, inquire into detected wheel of vehicle speed, sensing cylinder one end is equipped with speed probe; Drum wheelbase detects the wheelbase that regulating device is used for detecting and regulating master rotor and auxiliary cylinder, comprise roller shifting mechanism, wheelbase sensor, roller shifting mechanism one end is fixed on the frame, the other end links to each other with the auxiliary roller axis bearing, auxiliary cylinder does reciprocating linear motion along the guide rail on the frame under the effect of roller shifting mechanism, realize the wheelbase adjusting of master rotor and auxiliary cylinder, the size of wheelbase is by the reflection of wheelbase sensor; Strainer comprises stretcher, stretching pulley, and stretcher one end is fixed on the frame, the other end is equipped with stretching pulley, and stretching pulley is pressed against on the gearing, keeps the gearing elasticity not change with the wheelbase of master rotor and auxiliary cylinder; The rotor of charger and the axle head of master rotor are in transmission connection, and the stator of charger links to each other with frame by force transducer, and the spinner velocity sensor also is housed on the charger; Measurement and control unit and position transducer, wheelbase sensor, speed probe, force transducer, roller shifting mechanism, charger are electrically connected, the information that is used for the spinner velocity sensor of collection position sensor, wheelbase sensor, speed probe, force transducer and charger, control loaded device and roller shifting mechanism, storage and output testing result.
The maximum driving force that chassis dynamometer can detect, depend on the adhesion between wheel and the cylinder, on the twin-roll chassis dynamometer, adhesion between wheel and the cylinder, outside the Pass having with wheel load, attachment coefficient, also depend on the angle of setting of wheel between cylinder, angle of setting is big more, and the adhesion between wheel and the cylinder is also big more; Cylinder is also relevant with the angle of setting of wheel between cylinder to the longitudinal register effect of vehicle, and angle of setting is big more, and cylinder is also big more to the longitudinal register effect of vehicle.The angle of setting of wheel between cylinder is relevant with radius of wheel, radius roller and drum wheelbase, because radius roller is certain, after radius of wheel is determined, just can be by adjusting the method for drum wheelbase, adjust angle of setting, satisfy longitudinal direction of car location and driving force and detect requirement.
During detection, after the driving wheel of detected vehicle reaches between master rotor and the auxiliary cylinder, measurement and control unit is earlier inquired into radius of wheel according to the information of position transducer and wheelbase sensor and the radius of master rotor, the radius of auxiliary cylinder, the radius of sensing cylinder, detect the wheelbase that requires to regulate master rotor and auxiliary cylinder according to longitudinal direction of car location or driving force again, in the wheel drive roller rotating process, measurement and control unit loads to motor vehicle by the control loaded device, realizes that performances of motor vehicles detects or Work condition analogue; After detecting end, measurement and control unit makes auxiliary cylinder near master rotor by roller shifting mechanism, is convenient to wheel and rolls cylinder away from.
The beneficial effects of the utility model are: the utility model can maybe need detect driving force according to the different wheel radius and require to regulate automatically drum wheelbase, help guaranteeing accuracy of detection, need not vehicle is carried out longitudinal register, improve detection efficiency, need not to be provided with the wheel lifting mechanism between master rotor and the auxiliary cylinder, both can be used for single bridge and driven automobile, tractor detection, and also can be used for motorcycle and detect.
