Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the piston structure scheme drawing.
Among the figure: 1-ground engaging stabiliser wheel, 2-piston rod, 3-stage clip, 4-extension spring, 5-piston body, 6-lower bracket, 7-upper bracket, 8-brake system.
The specific embodiment
Further specify below in conjunction with the technical scheme of accompanying drawing, but the utility model is not limited in following embodiment the utility model.
As shown in Figure 1: emergency guarantee device after a kind of motor tire is blown out, it comprises ground engaging stabiliser wheel 1, piston rod 2, stage clip 3, extension spring 4, piston body 5, lower bracket 6, upper bracket 7 and brake system 8, wherein piston rod 2 is formed pistons with piston body 5.Said upper bracket 7 is installed on the automobile main beams; Piston body 5 tops are fixed on the upper bracket 7; Piston rod 2 passes lower bracket 6 and is connected with ground engaging stabiliser wheel 1, and simultaneously piston rod 2 links into an integrated entity with lower bracket 6, is connected through extension spring 4 between said lower bracket 6 and the upper bracket 7; And on the piston between lower bracket 6 and the upper bracket 7, be with stage clip 3, said brake system 8 connects ground engaging stabiliser wheel 1.During concrete operations ground engaging stabiliser wheel 1 is linked to each other with piston rod 2, it is one that piston rod 2 links with lower bracket 6, and guarantees that the three can do upper and lower motion simultaneously.Extension spring 4 is with upper bracket 7 and lower bracket 6 tensions and suitably compression; Make stage clip 3 and piston body 5 be in compressive state in the ordinary course of things; Ground engaging stabiliser wheel 1 is wheeled; Have brake system 8, this brake system 8 links to each other with automobile brake system through its BK Brake Switch, also can BK Brake Switch be set and directly link to each other with the brake system of automobile.And avoid secondary to blow out, the ground engaging stabiliser wheel wheel adopts solid rubber in addition.Stage clip 3 and piston body 5 amount of compression generally speaking are set to the height off the ground of ground engaging stabiliser wheel 1, and this is external to guarantee that under the safe prerequisite, its amount of compression can also be slightly larger than the radius of motor tire.After blowing out, can use like this as jack.Aforesaid brake system 8 also can adopt the existing conventional brake system.
As shown in Figure 2: this figure is the structure of piston scheme drawing; Wherein be separated into two parts in the piston body 5; A part is an oil cabinet, and a part is a piston chamber, between oil cabinet and piston chamber, is provided with anti-return check valve and oil return switch; Piston body 5 tops are provided with first unidirectional fuel feeding valve and the limiting valve, connect piston rod in the piston chamber.The principle of work of this piston with main effect is; When motor tire was blown out, 1 time rapid ground connection of ground engaging stabiliser wheel substituted original wheel, and this moment, piston rod 2 just can compression piston and stage clip 3 with lower bracket 6; When auto body reaches the bounce-back transformation point of stage clip 3 to its pressure that causes; Stage clip 3 begins bounce-back and drives piston to discharge together, and both power reaches free state with stage clip 3, this moment whole height of devices a little more than or the tire radius that equals to set; In bounce-back; The anti-return check valve and the first unidirectional fuel feeding valve in the piston are opened simultaneously, and the hydraulic oil sucker in the oil cabinet is indoor, and wherein to open be in oil cabinet, to produce vacuum to the first unidirectional fuel feeding valve.After the bounce of stage clip and the pressurized air in the piston have all discharged; Device will carry out the compression second time again under the effect of extension spring 4 and auto body pressure; This moment is owing to filled with hydraulic oil in the piston type, and check valve also closes under the pressure of piston back pressure, so piston can not be compressed; Or can only in the scope of setting, compress, thereby make this device reach the purpose of support vehicle body, maintenance balance.
When ground engaging stabiliser wheel 1 ground connection, it can drive the switch that lower bracket 6 upwards backs down brake system 8, makes the brake system of ground engaging stabiliser wheel and the brake system of automobile be communicated with.After tire is finished changing, open oil return switch and the lock of the location on the BK Brake Switch in the piston, whole device returns to initial condition.Secondly this device also can free folding and unfolding on auto body, can guarantee the cruising of automobile like this in many hollows location.This device also can use as stretching high device automatically as required.
