The protecting device aims to carry out support protection on the vehicle under an ultimate work station, ensure that the vehicle does not turn over, so that the test risk under the ultimate work station is reduced and the safety of manipulation of a driver and vehicle driving are guaranteed. The technical scheme provided by the utility model is as follows: the support protecting device for the transverse stability test of the commercial vehicle is composed of a through rod, a frame connecting mechanism, transverse connecting rods, axle tread connecting rods and axle treads, wherein the through rod is fixed on the frame connecting mechanism; the frame connecting mechanism is connected with two transverse connecting rods through bolts; the axle tread connecting rods provided with the axle treads are welded and then are connected with two ends of the transverse connecting rods through the bolts; and the frame connecting mechanism is connected with a frame through the through hole and the bolt.
Description
Technical field
The utility model relates to a kind of commerial vehicle test with supporting protective device, and particularly a kind of commerial vehicle lateral stability test belongs to the vehicle test field with supporting protective device.
Background technology
Lateral stability of cars is meant vehicle in the process of moving, externally can keep cruising state and direction under the interference effect, and unlikely generation is out of control and produce the ability of sideslip, racing and rollover phenomenon.
Vehicle is when receiving the effect of side direction wind, tempo turn or on wet and slippery road, turning to; Suffered transverse force usually near the limit of adhesion of tire or the state that reaches capacity, makes vehicle dynamics characteristics, particularly handles and obviously change of riding stability generation; The required control of vehicle is greater than the adhesion between tire and road surface in if go; Then vehicle is out of hand, thereby dangerous operating modes such as sideslip, racing and rollover appear in loses stability.
Can vehicle realize that it is most important prerequisite that safety turns to, keeps its lateral stability in the process of running at high speed.Under many circumstances, the driver also usually makes vehicle movement reach the ultimate limit state that tire and road surface are adhered in the reply of in case of emergency fear, thereby causes to lose control of one's vehicle and then occurrence of traffic accident.Therefore, how to control the running status of vehicle, vehicle can be gone according to driver's intention, prevent that vehicle from losing important content and direction that lateral stability becomes research and improves vehicle active safety technology.
Lateral stability of cars test is with supporting protective device, is the auxiliary support apparatus that a kind of support vehicles can safety traffic under limiting condition.When vehicle carries out the test of closed loop lateral stability; When causing the liftoff generation of vehicle one side wheel tire to turn on one's side owing to side acceleration is excessive; This device gives the vehicle supplemental support makes it keep normal trace to go, thereby has avoided the generation of vehicle rollover phenomenon, and then has ensured carrying out smoothly of test; Reduce the risk of test, guaranteed driver's personal safety.Therefore, this device can guarantee that experimental safe successfully carries out the visual plant of various limiting condition tests.
The utility model content
The utility model provides a kind of commerial vehicle lateral stability test with supporting protective device; Purpose is the vehicle under the test of closed loop lateral stability is propped up overfill protection; Guarantee the vehicle phenomenon of can not turning on one's side; Thereby reduced the empirical risk of closed loop lateral stability test, ensured the safety of pilot control and vehicle '.
The above-mentioned purpose of the utility model realizes that through following technical scheme accompanying drawings is following:
A kind of commerial vehicle lateral stability test is with supporting protective device; It is formed by connecting connecting link 1, vehicle frame bindiny mechanism 2, horizontal connecting link 3, wheel shaft tire connecting link 4 and wheel shaft tire 5; Said perforation connecting link 1 is fixed in the vehicle frame bindiny mechanism 2; Said vehicle frame bindiny mechanism 2 links together through bolt and 2 horizontal connecting links 3; The wheel shaft tire connecting link 4 welding back that wheel shaft tire 5 is housed is connected the two ends of horizontal connecting link 3 with bolt, and said vehicle frame bindiny mechanism 2 is connected on the vehicle frame with bolt through connecting connecting link 1.
The technique effect of the utility model: select a pilot hole in carriage frame antero posterior axis middle, the pilot hole size should satisfy the installation that connects connecting link 1 and vehicle frame bindiny mechanism 2.As there is not pilot hole or pilot hole is less; Can hole respectively according to the size that connects connecting link 1 in the centre position, both sides of vehicle frame symmetry; Vehicle frame bindiny mechanism 2 links together itself and vehicle frame with bolt through connecting connecting link 1; 2 horizontal connecting links 3 are connected together through bolt and vehicle frame bindiny mechanism 2, and tire is installed on the tire wheel shaft connecting link 4, are welded on then on the horizontal connecting link 3 to connect.
The course of work of the utility model is: when vehicle in process of the test; Cause a side wheel tire liftoff because of side acceleration is excessive, vehicle begins when an inclination, and the tire on the tire connecting link begins ground connection rotation; Laterally connecting link is delivered to the anchorage force of tire on the frame joint structure; Since frame joint structure with connect connecting link and link to each other with vehicle through bolt, so the anchorage force of tire is when being delivered to inclination sidecar frame, the vehicle frame of opposite side also can be shared the power of a part of support.Because the effect of tire anchorage force makes vehicle return to normal transport condition.

Embodiment
Following attachment figure illustrated embodiment example further specifies the particular content and the course of work thereof of the utility model.
Consulting Fig. 1, is the effect figure of the utility model new embodiment.
Consult Fig. 2, the utility model invention embodiment is: the commerial vehicle lateral stability supports protective device, comprises connecting bar 1, frame joint structure 2, horizontal connecting link 3, wheel shaft tire connecting link 4, wheel shaft and tire 5.
Consult Fig. 1-7, select a pilot hole in carriage frame antero posterior axis middle, the pilot hole size should satisfy the installation that connects connecting link 1 and vehicle frame bindiny mechanism 2.As there is not pilot hole or pilot hole is less; Can hole respectively according to the size that connects connecting link 1 in the centre position, both sides of vehicle frame symmetry; Vehicle frame bindiny mechanism 2 links together itself and vehicle frame with bolt through connecting connecting link 1; Two horizontal connecting links 3 are connected together through bolt and vehicle frame bindiny mechanism 2, and tire is installed on the tire wheel shaft connecting link 4, are welded on then on the horizontal connecting link 3 of vehicle frame both sides.
The course of work of the utility model is: when vehicle in process of the test; Cause a side wheel tire liftoff because of side acceleration is excessive, vehicle begins when an inclination, and the tire on the tire connecting link begins ground connection rotation; Laterally connecting link is delivered to the anchorage force of tire on the frame joint structure; Since frame joint structure with connect connecting link and link to each other with vehicle through bolt, so the anchorage force of tire is when being delivered to inclination sidecar frame, the vehicle frame of opposite side also can be shared the power of a part of support.Because the effect of tire anchorage force makes vehicle return to normal transport condition.
