Five working processs of the present utility model and principle.
First working process is base state (quiescence of no external force collision), as shown in Figure 2, hit plate (1), movable axis (3), clamp (18), push pedal (5), striking plate (23) position and do not have mobile phenomenon, sleeve pressure spring group (4), sleeve tension spring group (10), pressure spring group (7) do not have the elastic deformation that is subjected to external force and takes place, clamp (18) is drawn close with push pedal (5), and movable axis card wheel (22) is positioned between the clamp (18) and the first stressed wall (9).
Mode of operation when second working process is the low speed driving bump; (1-50 kilometer/hour of low speed ≈) as shown in Figure 3; when the anticollision of motor vehicles safety device that is installed on the self-propelled vehicle headstock or the tailstock is met the total elastic force of impact≤several sleeve pressure spring groups (4) that obstacle produced at the self-propelled vehicle low speed driving; hit be impacted power position change and drive push pedal (5) through movable axis (3) and separate of plate (1) with clamp (18); move to striking plate (23), card wheel (22) is drawn close or is not drawn close to clamp (18).Sleeve pressure spring group (4) pressurized generation elastic deformation, length are I degree compression, and having produced with the first stressed wall (9) is that the counteraction elastic force opposite with the impact direction at center is extenuated impact.Being fixed in the elasticity column plate (2) that hits on the plate (1) has the bump of the alleviating sound when being subjected to external force collision or running into obstacle, alleviate vibrations, extenuated the effect of fraction impact.
The 3rd working process be drive at moderate speed when bump mode of operation (middling speed ≈ 50-100 kilometer/hour) as shown in Figure 4; during the total elastic force of impact＞several sleeve pressure spring groups (4) that the self-propelled vehicle that is equipped with the anticollision of motor vehicles safety device is produced when meeting obstacle in driving at moderate speed; hit plate (1) and be impacted power, draw close or do not draw close to striking plate (23) after movable axis (3) drive push pedal (5) separates with clamp (18).Because moving of movable axis (3), card wheel (22) is drawn close clamp (18) and is driven clamp (18) and moves to second stressed wall (12) direction.Hit the position change of plate (1), clamp (18), push pedal (5), card wheel (22), striking plate (23) invariant position.Sleeve pressure spring group (4) length that is stressed is II degree compression, has produced counteraction elastic force.Sleeve tension spring group (10) is subjected to pulling force generation elastic deformation, length to be the expansion of I degree because of clamp (18) moves, having produced with the first stressed wall (9) is that the counteraction pulling force opposite with the impact direction at center extenuated impact.
The 4th working process is the mode of operation when running at high speed bump, (high speed ≈ 100-150 kilometer/hour) as shown in Figure 5, during the impact that the self-propelled vehicle that is equipped with anti-collision device is produced when meeting obstacle when running at high speed＞(the total elastic force of several sleeve pressure spring groups (the 4)+total elastic force of several sleeve tension spring groups (10)).Card wheel (22) drives clamp (18) and push pedal (5) is moved to striking plate (23), push pedal (5) bump striking plate (23), hit the position change of plate (1), clamp (5), card wheel (22), push pedal (5), striking plate (23), sleeve pressure spring group (4) length that is stressed is III degree compression, produces counteraction elastic force.Sleeve tension spring group (10) is subjected to pulling force length to be the II degree to expand, and produces the counteraction pulling force.Pressure spring group (7) the generation elastic deformation that is stressed, length are the compression of I degree, and having produced with the second stressed wall (12) is that the counteraction elastic force opposite with the impact direction at center is extenuated impact.
The 5th working process is the mode of operation of higher speed when running impact.(150-200 kilometer/hour of higher speed ≈) as shown in Figure 6, during the impact that the self-propelled vehicle that is equipped with anti-collision device is produced when meeting obstacle when higher speed travels=(the total elastic force of several sleeve pressure spring groups (the 4)+total elastic force of several sleeve tension spring groups (the 10)+total elastic force of several pressure spring groups (7)), reached the degree of saturation specific humidity in the elastic limit.Hitting the position of plate (1), card wheel (22), clamp (18), push pedal (5), striking plate (23) moves as the 4th mode of operation.Sleeve pressure spring group (4) length that is stressed is IV degree compression, produces counteraction elastic force.Sleeve tension spring group (10) is subjected to pulling force length to be the III degree to expand, and produces the counteraction pulling force.Pressure spring group (7) length that is stressed is II degree compression, produces counteraction elastic force and extenuates impact.This mode of operation has just in time reached the elastic force limit of the present utility model.Otherwise, greater than this total elastic force limit, will make anti-collision device and vehicle body impaired as impact.
Safe top plate zerk (8) inject make the lubricated liquid lubricating oil that reaches the works fine state of spring the utmost point in the short time oil leaking hole (6) pressurized on clamp (18), push pedal (5), striking plate (23) rapidly by the time, also can play the effect of extenuating the fraction impact.Oil outlet on the coffer base plate (14) then can all be emitted the lubricating oil in the coffer when repairing this safety device.Top board (19) and base plate (20) then can be opened when repairing this safety device sealing with coffer (11) at ordinary times.
The advantage of described utility model is to integrate the advantage of self-propelled vehicle elastic buffering mechanism and the advantage of self-propelled vehicle safety barrier, has the impact of extenuating, reduces the effect that shakes, prevents from directly to clash into the car body shell.The self-propelled vehicle of having realized installing anti-collision device in low speed, middling speed, at a high speed, higher speed four kinds of different speed travel and bump against or meet obstacle when producing impact, this safety device also can be extenuated impact by the different elastic force of basic, normal, high, higher level Four, thereby has avoided because of the too small factor that can not make this anti-collision device normal operation of the excessive impact of elastic force.It is convenient that this anti-collision device is sturdy and durable, safety performance good, vi have high safety, installing/dismounting are repaired, and self-return, advantage such as antitheft are arranged.Be applicable on all kinds of article such as various large, medium and small self-propelled vehiclees, elevator, winch.
