Inner side produces pressure with induction tooth, and the revolving force applied by motor can obtain the friction system with induction tooth on the inside of bogie wheel
Number, so as to test the frictional behavior on the inside of bogie wheel with induction tooth.
4. endurancing when on the inside of bogie wheel with induction tooth friction
By adjusting on the inside of bogie wheel with inducing the distance between tooth, make on the inside of bogie wheel and induction tooth produces pressure, it is electric
Machine 17 drives on the inside of driving wheel hub rotation, drive bogie wheel rotation, test bogie wheel durable during with induction tooth generation frictional force
Property.Rotary shock absorber can be chosen to install, the dynamic characteristic of bogie wheel is tested.
Torsion-bar spring adjusting method：
Choose proper stiffness torsion-bar spring, make bogie wheel and driving wheel hub between it is flexible contact, tried according to characteristic
Requirement is tested, elastic contact force F is determined.At the test condition, it is necessary to make bogie wheel center be in same horizontal line with wheel hub center
On, therefore, according to torsion bar rigidity, bogie wheel weight, and elastic contact force F, determine that the lower bogie wheel of nature pendency moves down away from
From, determine balance arm angle, under this constraints, as shown in figure 12, by torsion-bar spring from L-type pedestal open back groove (such as
Figure 11) insert, through the attached seat 13 of torsion-bar spring, and through the strip hole (such as Figure 10) of base, be connected with the internal spline 22 of balance arm 4
(such as Fig. 6).Now, then by slide plate it is adjusted to suitable distance so that bogie wheel is contacted with driving wheel hub, and is put down in same center
On face.
Before bogie wheel is installed, the pre-installation angle calcu-lation of balance arm and horizontal plane is as shown in figure 13.
It is as follows that it adjusts formula：
α0It is the pre-installation angle of balance arm and horizontal plane before bogie wheel is installed, unit is rad；α is that bogie wheel is installed simultaneously
Load after elastic contact force, the angle of balance arm and horizontal plane, unit is rad；M is the quality of bogie wheel, and unit is kg；G is
Acceleration of gravity m/s2；K is the rigidity of torsion-bar spring, and unit is Nm/rad；F is contact, and unit is N；L is balance arm
Length, unit is m.Above unit is international unit.
Arc-shaped base installation method with induction tooth：

The upper surface of the shape base of sector is led, creeper tread inner rubber is simulated.For some actual vehicle crawler belts inner side without rubber
Situation, very easily block rubber can be removed, after removal, bogie wheel and driving wheel hub between distance can be pushed away by leading screw
Enter institutional adjustment.
The method of adjustment of distance between bogie wheel and driving wheel hub：
The adjustment of distance, passes through the base with concave groove, slide plate, flat board, rolling between bogie wheel and driving wheel hub
Pin, leading screw propulsive mechanism etc..As shown in figure 9, due to needle roller be located at base (such as Figure 10) bottom with concave groove, slide plate with recessed
It is the less sliding pair of coefficient of friction between the base of type groove, can be rotated and promoted by leading screw propulsive mechanism, control slide plate
Transverse shifting.
Elastic damping element installation method：
As shown in fig. 6, in dynamically test, or when needing to simulate actual vibration insulating system, while installing torsion-bar spring (bullet
Property element) and rotary shock absorber (damping element).In dynamically test, rotary shock absorber can also play decay torsion bar bullet
The effect of torsional oscillation produced by spring.
In the actual vibration insulating system of simulating vehicle, torsion-bar spring and rotary shock absorber are worked in coordination, and form elastic damping system
System.Rotary shock absorber can also select other types of shock absorber from vane hydraulic shock absorber etc..Rotary shock absorber
Torque arm be connected by linking arm with balance arm.Linking arm is connected with rotary shock absorber torque arm, linking arm and balance arm, is to turn
Dynamic pair.Form linkage.
With the installation adjusting method of induction tooth contact on the inside of bogie wheel：
In the ideal case, two wheel sides of bogie wheel and induction tooth are discontiguous, and induction tooth position takes turns side in two
Center.However, in actual vehicle traveling, the skew of crawler belt can cause two wheel sides of bogie wheel all can be with induction tooth
Friction, therefore, has wear-resisting ring on the inside of two wheel sides of bogie wheel.The experimental rig of the present invention can be also tested under this operating mode
Bogie wheel frictional behavior and durability.
As shown in figure 8, especially by adjustment bogie wheel and balance arm between position, control bogie wheel on the inside of whether with band
Induce the induction tooth contact of the arc-shaped base of tooth, or contact.
The axle of adjustment ring 25, the investigation mission outside the city or town domain 26 and middle ring 27 in by adjusting outer nut 23, inner nut 24 and changing
To size, contact distance during with induction tooth generation friction can be adjusted on the inside of bogie wheel.Specific adjusting method is as follows：
As shown in figure 14, shown in Figure 15, outer nut 23 and inner nut 24 can be along the axle precession of balance arm 4 and back-outs, interior tune
The domain 25, the investigation mission outside the city or town domain 26, middle ring 27 and bearing and bogie wheel have relative determination relation, and because balance arm 4 is once pacified
Install into, its relative position is determined, therefore, by adjusting outer nut 23 and inner nut 24, can adjust bogie wheel along balance arm 4
