Background technology
Vehicle bridge is the important component part of automobile chassis running gear,Vehicle bridge is by suspension and vehicle frame（Or monocoque body）Phase
Even, automotive wheel is installed at two ends.Its function be transmission vehicle frame (or monocoque body) and wheel between all directions active force and its
Torque.Relative position according to vehicle bridge on car load can be divided into propons, jackshaft and back axle.
At present the brake side-slipping rate of propons has become commercial car, particularly the one of railway car manufacture enterprise and has mainly dispatched from the factory control
Index.In the event of this deviation fault, automobile braking safety will be affected, therefore, it is the offline section for meeting car load manufacturing enterprise
Clap and ex factory pass rate, need vehicle bridge manufacturing enterprise to solve this failure, and conventional meanses solve difficulty greatly, take a lot of work laborious.It is to make
Dynamic deviation fault is eliminated before the delivery of vehicle bridge manufacturing enterprise, with regard to needing a kind of device to examine propons left and right wheels brake synchronous
Survey, break-in can be carried out after discovery is unqualified, the purpose synchronous to reach left and right, it is to avoid after vehicle bridge to car load factory assembling, appearance
Brake side-slipping failure, reduces the fault rate of vehicle bridge factory.
The content of the invention
It is an object of the present invention to provide a kind of simple structure, can simulated implementation automobile front driving, gently stop, it is slow stop, emergency brake etc.
State, measures the stopping synchronous situation under the brake drum difference braking state of vehicle bridge both sides, so as to judge whether that can produce braking runs
The automobile front axle run-in stand of inclined failure and then raising automobile braking safety and the offline qualification rate of railway car manufacture enterprise.
The technical scheme is that：
A kind of automobile front axle run-in stand；Including power unit and testpieces fixture, power unit is arranged in symmetry shape, power
Testpieces fixture is arranged by slide rail symmetry shape between unit, it is characterised in that：Described power unit by motor, reductor and
Terminal pad is constituted, and motor is connected with reductor, and terminal pad is housed by shaft coupling on the output shaft of reductor；Described testpieces
Fixture is made up of connecting base plate, slide unit, base and support, and connecting base plate upper surface side is fixed with slide unit, the company of slide unit side
Connect and be fixed with chassis base, screw mandrel is equipped with by rotating disk on base, support is installed at the top of screw mandrel；Support and slide unit activity
Contact connection.
Testpieces is provided with described support and places mouth, cradle top is provided with pressing plate by connecting screw rod.
Be provided with chute on described slide unit, support side is provided with slide block corresponding with chute, support by slide block with
The cooperation of chute is slidably connected with slide unit.
The beneficial effects of the present invention is：
The automobile front axle run-in stand simple structure, strong adaptability is with low cost.In the course of work before energy simulated implementation automobile
Go, gently stop, it is slow stop, the state such as emergency brake, the stopping synchronous situation under the brake drum difference braking state of vehicle bridge both sides is measured, so as to sentence
The disconnected situation that whether can produce brake side-slipping；There is product to improving the offline qualification rate of automobile braking safety and railway car manufacture enterprise
The meaning of pole.

Fig. 2 for the present invention testpieces fixture structural representation.
In figure：1st, testpieces fixture, 2, slide rail, 3, motor, 4, reductor, 5, terminal pad, 6, connecting base plate, 7, slide unit,
8th, base, 9, support, 10, rotating disk, 11, screw mandrel, 12, testpieces place mouth, 13, pressing plate.
Specific embodiment
The automobile front axle run-in stand includes power unit and testpieces fixture 1, and power unit is arranged in symmetry shape, is moved
Testpieces fixture 1 is arranged by the symmetry shape of slide rail 2 between power unit.Power unit is by motor 3, reductor 4 and the structure of terminal pad 5
Into motor 3 is connected with reductor 4, and terminal pad 5 is housed by shaft coupling on the output shaft of reductor 4.
Testpieces fixture 1 is made up of connecting base plate 6, slide unit 7, base 8 and support 9, and the upper surface side of connecting base plate 6 is fixedly mounted with
There is slide unit 7, base 8 is fixed with the connecting base plate 6 of the side of slide unit 7, screw mandrel 11, screw mandrel 11 are equipped with by rotating disk 10 on base 8
Top support 9 is installed；Testpieces is provided with support 9 and places mouth 12, the top of support 9 is provided with pressing plate by connecting screw rod
13。
Chute is provided with slide unit 7, the side of support 9 is provided with slide block corresponding with chute, and support 9 is by slide block and chute
Cooperation be slidably connected with slide unit 7.
The automobile front axle run-in stand slide rail 2 can adjust the spacing between testpieces fixture 1, by the liftable of rotating disk 10
The height of screw mandrel 11, the purpose that support 9 is slidably connected with slide unit 7 is in the course of the work to Auxiliary support of support 9
Effect.
When the automobile front axle run-in stand works, according to propons product type, pressed from both sides by the Adjustment Tests part of slide rail 2 first
Position between tool 1, propons product is positioned over after the testpieces of support 9 placed mouth 12 and compressed by pressing plate 13, by turning
Disk 10 adjusts the height of screw mandrel 11, makes the centre of gyration of front axle hub brake drum contour with the centre of gyration of terminal pad 5 and therewith
