Abstract

It refers to a vehicle emergency brake and is featured that the balking belt is comprised by connecting the balking plates with many spring hinges; the top of the said balking belt is connected with the vehicle frame over the front of the wheels with a hinge axis; flexible guide belt is connected on the end of the balking belt; for the braked balking belt, the flexible guide belt and the end balking plate is laid under the wheels while the top balking plate is kept hanging over the hinge axis; the said end balking plate contacting the ground is a dentiform friction surface and the upper surface contacting the wheel is a smooth surface; the ropes to be wound in on the reel are provided and connected with the end balking plates. The balking plates not under braking conditions will be wound in over the front of the wheel with the ropes and kept locked. In case of emergencies, this model utility can emergently stop vehicles so as to reduce accidents.

Description

Automobile-used accident brake

Technical field:

The utility model relates to drg, more particularly the in case of emergency employed drg of power actuated vehicle especially.

Background technology:

At present, brake system of car all is to be provided with at the cruising operating mode, and braking procedure comprises tramples brake pedal, unclamps Das Gaspedal simultaneously, closes throttle, relies on pneumatic again or hydraulic pressure is braked automotive hub.This process is when trace is travelled, and is because the enough reaction time is arranged, comparatively reliable.But, when meeting emergency situation, because chaufeur is from finding dangerous situation, realize braking through judging, implement to brake that need the regular hour, vehicle braked can not be timely and effective, therefore causes the probability that traffic accident takes place to increase greatly.

Summary of the invention:

The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of automobile-used accident brake being provided, and when meeting emergency situation, vehicle is implemented emergency braking, with the generation of minimizing accident.

The technical scheme that the utility model technical solution problem is adopted is:

Constructional feature of the present utility model be by multistage hinder plate into by hinge of spring connect and compose the resistance forward (FWD), described resistance forward (FWD) is to be hinged on the vehicle frame that is positioned at position, wheel front upper place by hinge axis with its top; Not end at the resistance forward (FWD) connects the flexible guide band; Braking mode resistance forward (FWD) is that its flexible guide band and latter end hinder into the auxilliary pad of plate under wheel, and the top hinders into, and plate keeps being suspended on the hinge axis; Described latter end hinders into the plate one side of contacting to earth and is the dentation friction face, and the upper surface that contacts with wheel is a smooth side; But the drag-line of rolling in rotating shaft is set, and drag-line is connected the latter end and hinders on the plate, and non-braking mode resistance forward (FWD) is by the front upper place of drag-line folding at wheel, and keeps locking.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, the utility model under normal circumstances is folded state, does not influence the cruising and the braking of vehicle.

2, the utility model can adopt the mode of launching automatically that the resistance forward (FWD) is launched rapidly when meeting emergency situation, effectively shortens the reaction time.

3, the utility model hinders only advancing of car with the friction force that the resistance forward (FWD) that is deployed in the wheel below increases between wheel and the ground on the one hand, the wheel of high speed rotating skids because of smooth on the resistance forward (FWD) on the other hand, advancing of same prevention car, have good braking effect, shortened braking distance greatly.

Number in the figure: 1 wheel, 2 axletrees, 3 vehicle frames, 4 hinge of springs, 5 spring blocking plates, 6 reinforced supports, 7 drag-lines, 8 hinge axis, 9 track adjusting wheels, 10 self-lock switch control knobs, 11 motor switch control knobs, 12 self-lock switchs, 13 motors, 14 flexible guide bands, 15 latter ends hinder into that plate, 16 tops hinder into plate.

Below by embodiment the utility model is further described.

The specific embodiment:

Referring to Fig. 4, Fig. 5, present embodiment advances plate by three sections resistances and connects and composes the resistance forward (FWD) by hinge of spring 4, hindering in the latter end, the front end of plate 15 is connecting flexible guide band 14, flexible guide band 14 can be a steel mesh, for increase and ground between friction force, the one side of contacting to earth that the latter end hinders plate 15 into is the dentation friction face, and the upper surface that contacts with wheel 1 is a smooth side, and smooth side can skid wheel 1 thereon.

Referring to Fig. 1, Fig. 2, the resistance forward (FWD) is hinged on the vehicle frame 3 of the position, front upper place that is positioned at wheel 1 with its top by hinge axis 8, enormous impact power when braking for guaranteeing to hold out against, between hinge axis 8 and vehicle frame 3 reinforced support 6 is set, the height of hinge axis 8 can be higher than the height of axletree 2.

Shown in Figure 1, but the drag-line 7 of rolling in rotating shaft should be set, specifically be drag-line 7 to be connected the latter end hinder on the plate 15, run through each section resistance therebetween successively and advance plate, and walk around track adjusting wheel 9.

Shown in Fig. 3 (a), Fig. 3 (b), the resistance forward (FWD) of braking mode is that its flexible guide band 14 and latter end hinder into plate 15 auxilliary pads wheel 1 time, and the top hinders into, and plate 16 keeps being suspended on the hinge axis 8.

Shown in Fig. 3 (c), Fig. 3 (d), non-braking mode resistance forward (FWD) in the front upper place of wheel 1, and keeps locking by drag-line 7 foldings.

In order under normal circumstances to keep the resistance forward (FWD) for receiving overlapping state, the folded mechanism of automatic receipts is set, comprise drag-line 7, drag-line 7 is locked by self-lock switch 12 after reeling in the rotating shaft of motor 13, motor switch control knob 11 is set, presses the place near the steps control knob and can will hinder forward (FWD) by drag-line 7 and receive the state shown in Fig. 3 (d) that is stacked as.

In order to guarantee that in case of emergency the resistance forward (FWD) can launch smoothly, and the automatic developing machine structure is set, on the one hand, fixedly install resistance forward (FWD) spring by spring blocking plate 5, on the other hand, self-lock switch control knob 10 is set in the control loop of self-lock switch 12.When needing, directly press this self-lock switch control knob 10, then self-lock switch 12 is removed self-locking, under the effect of resistance forward (FWD) spring, drag-line 7 rapid debatchings hinder forward (FWD) simultaneously and launch, flexible guide band 14 is involved in by wheel 1 rapidly, and fills up under wheel together with resistance forward (FWD) 15 in latter end is together auxilliary, implements braking.In order to simplify structure, the folded mechanism of manual receipts also can be set, by manual coiling, the resistance forward (FWD) is received folded, receive poststack and lock with self-lock switch 12.

Concrete enforcement must be provided with synchronized operation in the car body bilateral symmetry.
