Embodiment
As Fig. 1-shown in Figure 6.The rolling chassis that is used for the test of automobile tumbling test, include the chassis chassis 5 of the frame-like of horizontal, be rotatablely equipped with road wheel respectively on the 5 both sides edges of chassis chassis, also include the table top 3 of getting on the bus of frame-like, the frame face of the table top of getting on the bus 3 is with respect to the frame face tilt acute angle angle on chassis chassis 5, and edge is installed on the 5 preceding edges of chassis chassis before the table top of getting on the bus 3, edge top, the table top of getting on the bus 3 both sides fixedly has a plurality of width respectively greater than the automotive wheel backing plate 2 of the table top 3 side frame hem width degree of getting on the bus, and automotive wheel backing plate 2 positions, both sides are corresponding symmetry one by one, be respectively arranged with a plurality of threaded holes 7 on each automotive wheel backing plate 2, the edge front portion is equipped with a pair of stop-motion seat 1 that extends forward before the chassis chassis 5, top, edge turning, 5 back, chassis chassis is respectively arranged with hinge bracket 10, be hinged with back support rod 11 on the hinge bracket 10 respectively, back support rod 11 tops are connected with spring-damper 4 respectively, bottom, 3 edge turnings also is provided with hinge bracket behind the table top of getting on the bus, and spring-damper 4 correspondence one by one is hinged on the hinge bracket of the edges bottom, table top 3 back of getting on the bus the spring-damper 4 outer butterfly springs that also are with successively, extension spring.Be provided with a pair of tie-beam parallel with 5 side frame limits, chassis chassis respectively in the chassis chassis 5, be respectively arranged with the anti-steel plate 8 that sticks up between two tie-beam front portions, the rear portion, anti-sticking up is respectively arranged with a plurality of safety cancellation through holes 9 on the steel plate 8, nullify safely and be installed with safety cancellation 6 in the through hole 9, and safety cancellation 6 bottoms are rotatablely equipped with angle sheave.
The frame face of the table top of getting on the bus 3 is with respect to frame face tilt 23 degree on chassis chassis 5.
Two automotive wheel backing plates are fixedly arranged respectively at top, the table top of getting on the bus 3 every side frame limit, one of them automotive wheel backing plate is made as tabular and is fixed on the table top side frame limit crown center of getting on the bus, the retaining that another automotive wheel backing plate front end turns on connecting along and be fixed on the table top side frame limit front end of getting on the bus.
The bottom of butterfly spring, extension spring is separately fixed at back support rod 11 tops, and butterfly spring, extension spring top are separately fixed on the spring-damper 4.
The utility model is laid four automotive wheel backing plates altogether on the table top both sides edge of getting on the bus, have a plurality of threaded holes of different sizes on each automotive wheel backing plate, these threaded holes are to solve the iron of carving that is used for installing and fixing automotive wheel, automobile slips at chassis and moves when avoiding drawing, and so just can realize dissimilar automotive tests according to adjusting threaded hole.
The utility model is furnished with the stop-motion seat of two covers, and position can be adjusted according to test planning, and on embedded iron floor, relevant position, symmetrical size is decided according to the chassis width dimensions.Can install 8 on each stop-motion seat and only stop pin (the white steel pipe of overcoat during work), the wall thickness of the quantity of actual required mount pin and white steel pipe need be demarcated, and timing signal is earlier from low speed 20km/h, and every 5km/h demarcates once, until the speed per hour of demarcating rules and regulations.
When the traction of rolling chassis, on the safe kingpin bore position of anti-seesaw, load onto angle sheave, chassis sideslip in the time of can avoiding drawing by the safety cancellation.
Automobile is loaded on the automotive wheel backing plate of rolling chassis during use, and the rolling chassis makes chassis along correct direction running because the tractive force setting in motion prevents that the angle sheave that sticks up safety post pin-and-hole position on the steel plate play the guiding role this moment.When the rolling chassis reaches the needed speed of experiment, stop-motion seat collides with in advance pre-buried iron floor, this moment, automobile rolled away owing to being subjected to huge inertial force, chassis is got on the bus table top and chassis chassis owing to be subjected to impulsive force, retrousse trend is arranged, along with the center of gravity migration, connect that extension spring is stretched on the back support rod of get on the bus table top and the chassis extreme end of chassis corner this moment, and the butterfly spring of extension spring inside also is subjected to stretching action, because butterfly spring has good buffering vibration absorption ability, therefore it and extension spring produce elastic potential energy jointly, the oriented trend that is stretched and shrink is in the other direction turned in the continuation of the table top of so just can avoiding greatly getting on the bus.That installs on the chassis chassis anti-ly sticks up the gravity that steel plate has increased the chassis chassis; causing the chassis chassis not followed turns over; rest on the original place or the angle that turns on very little arranged, thus fabulous protection bogie wheels owing to turn on the inertia fall the damage that back and collision on the ground cause again.
