Abstract
The utility model relates to an emergency brake device for motor vehicles, composed of a control rod, a drive rod and a braking member. The upper end of the braking member is movably connected to a chassis which is arranged in front of rear wheels of a motor vehicle, the lower end is sheathed on the drive rod, and the drive rod is connected with the control rod which is arranged in a cab. The movements of the motor vehicle can be prevented by clamping the braking member between the rear wheels and the ground, so that the purpose of emergency braking can be obtained, so that traffic accidents can be reduced.
Description
The utility model relates to the appurtenances of self-propelled vehicle, specifically is the brake equipment of self-propelled vehicle.
The brake equipment of existing self-propelled vehicle is made up of the brake wheel that the wheel hub of control piece, Transmission, drag friction part and wheel is combined into one.When self-propelled vehicle needs glancing impact, operate control piece, by Transmission drag friction part and brake wheel are rubbed, prevent wheel, thereby realize the self-propelled vehicle braking.But when the moving velocity of self-propelled vehicle is very fast,, prevented wheel fully although the drag friction part has tightly been embraced brake wheel, yet because effect of inertia, self-propelled vehicle will slide a segment distance along the road surface, and speed is fast more, coasting distance is long more.This situation then usually can cause the generation of traffic accident.
Chinese patent CN86210173 discloses a kind of self-propelled vehicle stop motion mechanism of speedily carrying out rescue work, and this device is main to be put down the reset components that can make brake component mention return after the brake component that contacts to earth and dangerous situation are eliminated and form by control piece, Transmission, when speedily carrying out rescue work stop.Its brake component is to make rod-like element with metallic material, has certain angle of inclination when speedily carrying out rescue work stop between shaft-like brake component and the ground, is beneficial to brake component and inserts ground.When self-propelled vehicle runs into emergency situation, the drag friction part has been adjacent to brake wheel, prevented wheel fully, but when self-propelled vehicle still slides forward with the inertia that moves, the operation control piece puts down the shaft-like brake component that can contact to earth through Transmission, inserts it into ground, utilize ground-surface resistance to overcome the inertia of self-propelled vehicle motion, make automobile forced stop.Dangerous situation is mentioned the brake component return by reset components after eliminating.
Though the stop motion mechanism that this patent provides can overcome the self-propelled vehicle motional inertia effectively, reach the purpose of forcing stop, this apparatus structure is too complicated, makes the self-propelled vehicle bottom increase many parts again.Particularly this device is to utilize the purpose that ground reaches stop is inserted in shaft-like braking, but self-propelled vehicle is not to be that brake component is once inserting ground stop fully, but still have moving of part, this just will inevitably cause brake component with pavement destruction, make troubles for the driving of back, undoubtedly, destroyed with the road surface is the stop that cost realizes self-propelled vehicle, is not to be optimal scheme.
The purpose of this utility model provides a kind of simple in structure, the self-propelled vehicle emergency braking apparatus that can prevent self-propelled vehicle motion effectively.
The self-propelled vehicle emergency braking apparatus is made up of control stalk, drive link and brake component, and brake component upper end is movably connected on the chassis before the self-propelled vehicle rear wheel, and the lower end can be enclosed within on the drive link, and drive link links to each other with control stalk in being installed in operator's compartment.When the needs emergency braking, the operation control stalk drives the drive link reach, causes brake component and drive link to break away from also and falls naturally, and the brake component that falls stretches into rear wheel it is blocked, and self-propelled vehicle can not be moved again, thereby reaches the purpose of emergency braking.
In order to increase friction force, improve braking effect, the circular arc that is complementary with wheel is made in the inboard of brake component, the base plane of brake component is provided with saw shape tooth.
Lift brake component, control stalk is resetted, move behind the drive drive link, brake component is enclosed within on the drive link, can restore to the original state.
Can be connected with iron chains between brake component and the drive link.
Table utility model self-propelled vehicle emergency braking apparatus is simple in structure, does not destroy the road surface, and because brake component is to block wheel in large area, do not allow it advancing slip, therefore can more effectively shorten the self-propelled vehicle stopping distance, it is braked quickly, reduce or avoid taking place traffic accident.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, the self-propelled vehicle emergency braking apparatus is made up of control stalk 1, drive link 2 and brake component 5, and brake component 5 upper ends are movably connected on the preceding chassis of self-propelled vehicle rear wheel, and the lower end is enclosed within on the drive link 2 by iron chains 3, drive link 2 links to each other with control stalk 1, and control stalk 1 is installed in the operator's compartment.Make and the corresponding to circular arc of rear wheel curvature the inboard of brake component 5, and base plane is provided with one group of saw shape tooth 4, and brake component adopts hard metal material to make.
The utility model emergency braking apparatus is not only applicable to truck conspicuity marking, is fit to small-sized or the Agricultural automotive vehicle use yet.
