Spline connection, live axle are installed rotary encoder, measure road wheel rotary speed information in real time away from decelerator one end, end.Can
Movable stand is arranged on above moving guide rail, and steady pin rack rails is arranged on above removable stand with adjustable pin rack rails, if by
Dry bolt and nut are connected with removable stand；Moving guide rail upper surface has two inverted T-shaped grooves, may move stand following table
Face has two inverted T-type structures, there are two inverted T-shaped grooves to be connected with moving guide rail lower surface, it is ensured that removable stand
Move horizontally along the groove, may move stand upper surface and there are two inverted T-shaped grooves and several arc-shaped grooves, connect adjustable pin
The bolt head of rack rails can be moved in the arc groove, make certain level is formed between steady pin rack rails and adjustable pin rack rails
Angle of bend, the bolt head of the pin tooth that is connected rail are arranged in the removable inverted T-shaped groove of stand upper surface two, can be by being somebody's turn to do
Part-structure changes the pin tooth rail of different model；When requiring there is vertical angle of bend between steady pin rack rails and adjustable pin rack rails
When, can between adjustable pin rack rails and removable stand mounting and adjusting cushion block, the adjustment cushion block profile is with certain thickness
Trapezoid block, upper surface with lower surface at an angle, can adjust the vertical angle of bend between steady pin rack rails and adjustable pin rack rails；
Steady pin rack rails has identical design feature with moving pin rack rails, and which is made up of two track plates and several pin tooths, track plates
Side arrangement has several through holes, and the through hole cross sectional shape is identical with pin tooth cross sectional shape, for installing pin tooth, track plates upper table
Face is disposed with some round thread holes.
Can adjust vertical curved between steady pin rack rails and adjustable pin rack rails by using the adjustment cushion block of differing tilt angles
Bent angle.The connecting bolt of adjustable pin rack rails can be rotated in arc-shaped slot, between adjustment steady pin rack rails and adjustable pin rack rails
Vertical angle of bend.
Usefulness of the present invention is：（1）Underground working can be simulated, conveyer is carried out and be there is horizontal curvature angle and vertical
Walking experiment under angle of bend；（2）When synchronously tested road wheel angular speed and angular acceleration curve in fact；（3）Achievable different shaped
The dynamic characteristic test of number walking mechanism.Therefore, with certain economic benefit.
