CN2071606U - External emergence braking apparatus for automobile - Google Patents

Abstract

The utility model discloses an auxiliary braking apparatus for automobile emergency braking. Two steel beams are welded on the steel frame of an automobile body at the front and back parts of both rear wheels. Both ends of each steel beam are fixed with a pair of track chains with tooth tips made of steel or other materials. When the automobile runs, the track chains are hung at the front and the back parts of the rear wheels and doubles as mud baffles. When emergency braking situation occurs, the track chains are quickly dropped down by a control system. The front track chains can be dropped down for stopping the automobile to move forward, and the back track chains can be dropped down for stopping the automobile to move backward. The utility model is matched with ordinary brakes together for the automobile emergency braking.

Description

External emergence braking apparatus for automobile

The utility model relates to a kind of later-model automobile emergency brake.Be fit to design and installation on various power actuated vehicles.

Existing automobile braking device mainly adopts the inside brake mode, and relevant brake gear promptly is installed on the axis of wheel rotation of automotive interior.The technical comparative maturity of these brake gears, under the relatively poor condition of the strong condition of car, its braking effect is often not ideal enough.Therefore, existing automobile braking device is in certain limitation.

Task of the present utility model is that a kind of later-model automobile will be provided, brake gear, and it is as travelling on relatively poor road conditions or the automobile of fast running is implemented a kind of important auxiliary device of emergency brake.

The utility model is achieved in that the front and back place welding two steel part crossbeams of the trailing wheel crossbeam on the vehicle body steelframe, and at the crawler belt that is stretching out device steel band crown on the part crossbeam of vehicle body steelframe, its length is being that trailing wheel and ground are clamped and exceeded.During automobile normal running, make crawler belt be suspended in the trailing wheel front and back in the air by control system, its crawler belt at this moment muddy water baffle plate of double as trailing wheel is used.When meeting the emergency brake situation, by control system crawler belt is dropped rapidly, trailing wheel is clamped crawler belt immediately, and the crawler belt of steel band crown contacts with ground, has increased automobile back wheel and ground-surface friction force, and automobile is stopped rapidly.

Should keep opening time of the present utility model synchronous with the opening time of other brake gears of automobile.To this, these brake gears should be controlled by two operating units that are closely related.Design and installation of the present utility model and use are more convenient, and cost is not too high.The utility model is applied in and often travels on smooth road or the silt particle ground-surface automobile, and effect is better.If do not consider to retreat the emergency brake situation, the steel crossbeam at trailing wheel rear portion then, corresponding steel band crown crawler belt, controller, control path can not installed.

Below in conjunction with accompanying drawing utility model is described in further detail.

Fig. 1 is the lateral plan of a kind of concrete structure of the present utility model.

Fig. 2 is the order mansion view of a kind of concrete structure of the present utility model.

See figures.1.and.2, be fixed on the both sides of two steel part crossbeams (2) of place, the front and back welding of trailing wheel (7) crossbeam on the vehicle body steelframe (1) by the crawler belt (4) of steel band crown.Going up outstanding and dropping of the crawler belt (4) of steel band crown realized by control path (5) by controller (6).Controller (6) can be made of electromagnetic component, and control path (5) can be replaced by steel wire.When the automobile in advancing need be realized emergency brake, controller (6) by control path (5), made crawler belt (4) tenesmus rapidly of steel band crown according to instruction; When after finishing the emergency brake task, preparing to advance again, automobile can be moved back a bit after a while, by controller (6) and control path (5) steel band crown crawler belt be risen to overhead positions more afterwards.When the automobile in retreating need be realized emergency brake, controller (6) passes through control path (5 ') according to instruction, make crawler belt (4 ') tenesmus rapidly of steel band crown, when after finishing the emergency brake task, preparing to advance again, automobile can be marched forward a bit slightly, by controller (7) and control path (5) steel band tooth crawler belt be risen to overhead positions more afterwards.

Claims (5)

1, automobile is braked the auxiliary brake that emergency brake arrangement is automobile enforcement emergency brake outward, it is by girder steel (2), band pointed tooth crawler belt (4), (4 '), control path (5), (5 '), controller constitutes, it is characterized in that being with sharp-toothed crawler belt (4), (4 ') be that device is at the automobile back wheel forward-and-rearward.

2,, it is characterized in that to be clamped by wheel and ground after length with sharp-toothed crawler belt (4), (4 ') drops fully with it and exceed by the brake gear of claim 1 regulation.

3,, it is characterized in that controlling by control path (5), (5 ') according to instruction by controller (6) with the action of sharp-toothed crawler belt (4), (4 ') by the brake gear of claim 1 regulation.

4,, it is characterized in that with pointed tooth crawler belt (4), (4 ') is that device is on girder steel (2) by the brake gear of claim 1 regulation.

5, want the brake gear of 1 regulation by right, it is characterized in that girder steel (2) is fixed on the vehicle body steelframe (7).
