Automobile passability test runway of the present utility model is connected by the smooth runway of front portion and the arch runway at rear portion and forms, and described smooth runway is provided with recess, and described recess is provided with movable block, and the end face of described movable block exceeds described smooth runway.
This automobile passability test runway realizes the checking of vehicle dynamic by property mainly through the angle in the length of ramp arch runway self, angle and adjacent ramp, can avoid the interference of vehicle and runway at proof procedure simultaneously.Concrete test is as follows:
1, minimum ground clearance checking:
Auto model is to specify that the speed of a motor vehicle is by smooth runway.
If there is the situation that vehicle part contacts with movable block, then this vehicle minimum ground clearance does not meet by the requirement of property minimum standard; Because movable block realizes highly regulating by more bringing, can verify and evaluate vehicle minimum ground clearance numerical value further.
If there is not vehicle part to contact with movable wooden unit, then this vehicle minimum ground clearance meets by the requirement of property minimum standard.
2, approach angle checking:
Auto model is to specify the joint (i.e. approach angle validation region) of the speed of a motor vehicle by smooth runway and arch runway.
If there is vehicle part to contact with approach angle validation region, then this vehicle approach angle does not meet by the requirement of property minimum standard; Can reduce the speed of a motor vehicle and slow transit through when there is contact, and record is so that post analysis, if cannot by or vehicle part gross distortion time, should stop immediately, avoid vehicle and runway impaired.
If there is not vehicle part to contact with approach angle validation region, then this vehicle approach angle meets by the requirement of property minimum standard.
3, ramp breakover angle checking:
Auto model is to specify that the speed of a motor vehicle is by arch runway (i.e. ramp breakover angle validation region).
If there is vehicle part to contact with ramp breakover angle validation region, then this longitudinal direction of car is not met by the requirement of property minimum standard by angle; The speed of a motor vehicle can be reduced slow transit through when there is contact, if cannot by or vehicle part gross distortion time, should stop immediately, avoid vehicle and runway impaired.
If there is not vehicle part to contact with ramp breakover angle validation region, then this longitudinal direction of car is met by the requirement of property minimum standard by angle.
4, departure angle checking:
Auto model is to specify the rear end (i.e. departure angle validation region) of the speed of a motor vehicle by arch runway.
If there is vehicle part to contact with departure angle validation region, then this vehicle departure angle does not meet by the requirement of property minimum standard; The speed of a motor vehicle can be reduced slow transit through when there is contact, if cannot by or vehicle part gross distortion time, should stop immediately, avoid vehicle and runway impaired.
If there is not vehicle part to contact with departure angle validation region, then this vehicle departure angle meets by the requirement of property minimum standard.
Further, for reducing or avoiding the infringement to automobile chassis, described movable block is wooden unit or foam block.
Further, for ensureing safety and checking body width, the both sides of described arch runway are provided with guard rail; The joint of described smooth runway and arch runway is provided with speed limitation board.
Automobile passability test track elements of the present utility model is simple, practical, not fragile, can provide good testing standard for automobile passability.
Accompanying drawing explanation
Fig. 1 is the structural representation of automobile passability test runway of the present utility model.
Fig. 2 is automobile passability test philosophy figure.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect and principle of work etc. of embodiment of the present utility model as the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part are described in further detail.
Embodiment 1:
As shown in the figure, the automobile passability test runway of the present embodiment is arranged side by side two, be respectively used to the checking of Sedan and SUV Dynamic vehicle by property, wherein the automobile passability test runway of every bar connects by the smooth runway 1 of front portion and the arch runway 2 at rear portion and forms, described smooth runway 1 is provided with recess, described recess is provided with movable wooden unit 3, and the end face of described movable wooden unit 3 exceeds described smooth runway 1.
For ensureing safety and checking body width, the both sides of described arch runway 2 are provided with guard rail 4; Described smooth runway 1 is provided with speed limitation board 5 with the joint of arch runway 2.
Vehicle by direction be smooth runway 1 to arch runway 2, avoid back through, and by time need observe the speed of a motor vehicle limit value regulation.
This automobile passability test runway realizes the checking of vehicle dynamic by property mainly through the angle in the length of ramp arch runway 2 self, angle and adjacent ramp, can avoid the interference of vehicle and runway at proof procedure simultaneously.Concrete test is as follows:
1, minimum ground clearance checking:
Auto model is to specify that the speed of a motor vehicle is by smooth runway 1, the a-quadrant namely in Fig. 2.
If there is the situation that vehicle part contacts with movable block, then this vehicle minimum ground clearance does not meet by the requirement of property minimum standard; Because movable block realizes highly regulating by more bringing, can verify and evaluate vehicle minimum ground clearance numerical value further.
If there is not vehicle part to contact with movable wooden unit 3, then this vehicle minimum ground clearance meets by the requirement of property minimum standard.
2, approach angle checking:
Auto model is to specify that the speed of a motor vehicle is by the joint of smooth runway 1 with arch runway 2, the B region (i.e. approach angle validation region) namely in Fig. 2.
If there is vehicle part to contact with approach angle validation region, then this vehicle approach angle does not meet by the requirement of property minimum standard; Can reduce the speed of a motor vehicle and slow transit through when there is contact, and record is so that post analysis, if cannot by or vehicle part gross distortion time, should stop immediately, avoid vehicle and runway impaired.
If there is not vehicle part to contact with approach angle validation region, then this vehicle approach angle meets by the requirement of property minimum standard.
3, ramp breakover angle checking:
Auto model is to specify that the speed of a motor vehicle is by arch runway 2, the C region (i.e. ramp breakover angle validation region) namely in Fig. 2.
If there is vehicle part to contact with ramp breakover angle validation region, then this longitudinal direction of car is not met by the requirement of property minimum standard by angle; The speed of a motor vehicle can be reduced slow transit through when there is contact, if cannot by or vehicle part gross distortion time, should stop immediately, avoid vehicle and runway impaired.
If there is not vehicle part to contact with ramp breakover angle validation region, then this longitudinal direction of car is met by the requirement of property minimum standard by angle.
4, departure angle checking:
Auto model is to specify the rear end of the speed of a motor vehicle by arch runway 2, the D region (i.e. departure angle validation region) namely in Fig. 2.
If there is vehicle part to contact with departure angle validation region, then this vehicle departure angle does not meet by the requirement of property minimum standard; The speed of a motor vehicle can be reduced slow transit through when there is contact, if cannot by or vehicle part gross distortion time, should stop immediately, avoid vehicle and runway impaired.
If there is not vehicle part to contact with departure angle validation region, then this vehicle departure angle meets by the requirement of property minimum standard.
Automobile passability test runway of the present utility model is fixed sturcture, and its each checking angle does not possess regulatory function, cannot be verified, be only the minimum standard that vehicle dynamic is verified by property to specific vehicle by property.
