Description
Technical field
The present invention relates to loader for detecting self-changing gearbox of automobile.
Background technology
Automatic transmission can make automobile obtain good dynamic property and fuel economy according to the automatic conversion ratio of gear of situations such as the engine load and the speed of a motor vehicle, and reduces engine emission and pollute.For repairing, the inspection of automatic gear-box, normally be installed on the automobile and carry out, the repairman often will repair and check repeatedly like this, labour intensity is very big, and the diagnosis of failure cause difficulty or ease.Be used for detecting gearbox shifting, solenoid valve duty, moment of torsion, the isoparametric gearbox testrigs of speed ratio at present.Gearbox testrigs generally has load machine, and load machine has the torque control device, and the torque control device is used for to the wheel box imposed load, simulates different driving cycles.The utility model patent instructions of China Granted publication CN 2580430Y discloses a kind of automatic gearbox of vehicles machines, and its load machine takes the current vortex device as the torque control device.Load machine and wheel box are in transmission connection, start drive unit and drive the wheel box rotation, iron-core coil to the current vortex device feeds exciting current simultaneously, the magnetic line of force that iron core produces enters eddy-current disc by air-gap, eddy-current disc is continuous cutting magnetic line under the drive of wheel box, in dish, form continuous current vortex, current vortex is subjected to the electromagnetic force opposite with eddy-current disc direction of motion in magnetic field, this electromagnetic force passes to automatic gear-box to be measured by eddy-current disc and transmission shaft, equal to have added a certain amount of torque load to wheel box, this load is mainly used to the simulated air resistance, the variation of grade resistance and resistance to rolling, the size of load can realize by regulating exciting current.But the load machine of above-mentioned machines is not because there is special simulation inertia load device, the moment of inertia of itself is very little, greatly differ from each other with the driving cycle of automobile on road, therefore testing table (machines) can not be finished the integration test to the automatic gear-box performance, the performance of the automatic gear-box after the maintenance how, also wants entrucking to carry out actual road test and could determine.Machines does not in the past require the shift quality that yet can not detect automatic gear-box to be measured.So the combination property that will finish on machines automatic gear-box detects, and replaces actual road test, and the load machine of a real simulated automotive of energy in the travels down situation must be arranged.
Summary of the invention
The objective of the invention is to propose the loader for detecting self-changing gearbox of a kind of energy simulated automotive in the travels down situation.
For achieving the above object, the present invention takes following technical scheme:
The loader for detecting self-changing gearbox of automobile that the present invention proposes, comprise control desk, be fixed on torque control device and observing and controlling case on the control desk, connect a Rzeppa constant velocity joint driving-shaft assembly on the input shaft of torque control device, be provided with flywheel shaft in the control desk bottom, flywheel shaft is by the pair of bearings seat supports that is fixed on the control desk, be fixed with flywheel on the flywheel shaft, be connected by speed increasing mechanism between one end of flywheel shaft and the input shaft of torque control device, the other end of flywheel shaft connects a hydraulic brake system by Connection Block.
The flywheel that is fixed on the flywheel shaft is two, is in the outside of diaxon bearing respectively.
Described speed increasing mechanism is the belt gear speed increasing mechanism.
Described torque control device comprises generator and electrical appliance, and generator is powered to electrical appliance.
Described torque control device can be the current vortex device.
The present invention is to the wheel box input torque, and wheel box is to torque control device output torque, torque control device consumed power, and this is the variation of simulated air resistance, grade resistance and resistance to rolling.Owing to have the flywheel inertance element, from requirement to automatic transmission gear shift quality (shift impact), the huge inertia of automobile is main cause, change so the introducing of inertance element can be simulated inertia load, use the testing table (machines) of this load machine can detect automatic gear-box in the shift impact fault that starts in quickening, slowing down.The combination property of finishing in testing table automatic gear-box detects, and replaces actual road test.
Description of drawings
For the easier quilt of content of the present invention is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the configuration diagram of embodiment 1;
