Abstract
The utility model relates to an emergency braking floor friction device for automotive vehicles, which is composed of a plate buckle, a support framework and a top pump. The utility model can be fixed on a vehicle chassis, the support framework can be controlled by an emergency brake to do lever motion, and accordingly, a friction block can be tightly pressed against the ground to produce resistance, so that the inertia rush of vehicles can be overcome, and traffic accidents can be avoided or reduced.
Description
The utility model be a kind of device on motor-vehicle chassis, utilize accident brake control friction shoe, compress ground and produce friction and overcome vehicle inertia and stop vehicle to slide forward, the device that impels vehicle to stop rapidly belongs to the vehicle assembly class.
World today's self-propelled vehicle has become the main tool of land traffic, is example with the automobile, and at present world's owning amount has reached more than 500,000,000, and is annually also increasing progressively with 43,000,000 speed.Vehicle has also caused many accidents to people bringing convenience to people efficiently simultaneously, and the reason of accident is many-sided, and with regard to vehicle is a big factor that causes the accident not reaching ideal effect aspect the braking itself.Present drg is such as hoof---drum brake mechanism, plate disc brake, external contracting drum brake, engine exhaust and brake device, electric eddy current brake, fluid power checking brake etc., their effect is all brought into play aspect one of control vehicle self braking so can not overcome the vehicle inertia set forward, causes under the situation that the vehicle displacement all stops because inertia also can slide a segment distance forward.The much longer more accident of the fast more coasting distance of the speed of a motor vehicle all occurs in the inertial collision aspect of vehicle.
The purpose of this utility model provides a kind of the device on vehicle chassis, when doing emergency brake, accident brake friction shoe wink the compress ground-surface self-propelled vehicle emergency braking of device on frame chassis can be landed friction gear, utilize the ground increase and the friction of vehicle body to stop the advancing slip purpose of vehicle inertia to reach, make it to reduce traffic accident.
Realize that concrete scheme of the present utility model is: on the chassis of vehicle by adorning a flexible frame, at ordinary times an end of framework be laid in link to each other with the accident brake pull bar by and buckle by the pulling of elastic telescopic that have of drg control, when emergency braking, pull button and be subjected to the traction of drg pull bar and indentation, at this moment framework is made the end that lever motion quickly will be equipped with brake pad immediately and is compressed ground under the effect of spring force, and the other end enters in the deck that is fixed on the vehicle frame simultaneously.Like this since the vehicle coherence slide forward cause the friction of friction shoe and ground to produce that coherence that resistance overcomes vehicle reduces vehicle to slide and left alone without help rapidly firmly.Can the top pump of use device on vehicle chassis framework jack-up be made it parallel after removing emergency brake, the end that at this moment friction shoe be housed is just pulled button and is put among the elastic force compressing that makes whole framework be in spring.Pull during emergency brake once more detain again the indentation friction shoe once more bullet press down face tightly, play the effect that stops vehicle to slide.In addition, because a cooling heat dissipation case is set on friction shoe, the heat that produces in the time of can be friction leaves rapidly so can not cause burning.
Overcome the resistance of vehicle coherence preshoot because the utility model can utilize ground to make vehicle body and ground produce friction formation indirectly, thereby reach minimizing, stop the vehicle purpose that coherence slides forward after emergency brake.This function that can utilize ground friction to produce to stop the vehicle coherence to slide is that present drg is not available.Using the utility model cooperates the emergency braking effect that will make vehicle to reach a new high with existing drg.
Accompanying drawing 1 is an overall structure scheme drawing of the present utility model.
Accompanying drawing 2 is structural representations of cooling heat dissipation case of the present utility model.
Below in conjunction with drawings and Examples the utility model is further described:
Among the figure: 1, pull button 2, stage clip 3, supporting frame 4, solid axle bed 5, bearing seat
6, axle thick stick 7, extension spring 8, top pump 9, deck 10, cooling heat dissipation case
11, brake pad 12, catching groove 13, bolt hole 14, heat radiation clamping plate
Be connected with drg pull bar on the vehicle as pulling one of button (1) among Fig. 1, its other end and catching groove (12) coupling can be pulled button (1) and be put when catching groove (12) rises.The two ends that have the axle thick stick (6) of two bearing seats (5) have two solid axle bed (4) bearing seats (5) to be fixed on the supporting frame (3), Gu axle bed (4) is fixed on the chassis of vehicle.Be equipped with on two end faces on supporting frame (3) stage clip (2) and extension spring (7) the effect of a top pump of anchor fitting (8) stage clip (2) and extension spring (7) on that the vehicle chassis on top, center of extension spring (7) be by supporting frame (3) with friction shoe (11) bullet under and compress on the ground.The effect of top pump (8) is that head of scratching on the supporting frame to be subdued to make supporting frame (3) be that fulcrum is done lever motion and risen to the equal catching groove (12) that makes it with vehicle chassis until supporting frame (3) and pulled and buckle till (1) put with axle thick stick (6).Fix a deck (9) on the vehicle frame at vehicle chassis rear portion, its effect is withstood that head of scratching on the supporting frame and is born upwards backward the thrust that ground awards friction shoe (11).Friction shoe (11) by bolt hole (13) be fixed on inside be equipped with the heat radiation clamping plate (14) cooling heat dissipation case (10) under, cooling heat dissipation case (10) is fixed on the bottom surface of supporting frame (3) one ends.When chaufeur is done emergency brake, because the drg pull bar has affected and has pulled button (1) and pull out from catching groove (12) pulling button (1), so the supporting frame (3) that is in the elastic force compressing of stage clip (2) and extension spring (7) is that the center makes friction shoe placed on it (11) compress ground do lever motion with supporting frame (3) with axle thick stick (6) quickly, and its other end enters deck (9) and withstood.The heat that brake pad and ground friction produce passes to cooling heat dissipation case (10) by heating panel (14) and is cooled and leaves.After emergency braking is removed, top pump (8) work promotes supporting frame (3) and recovers parallel, also stage clip (2) is compressed simultaneously, and extension spring (7) is elongated, when catching groove (12) by being pulled button (1) when putting, supporting frame (3) just is among anxiety waits that the elastic force of sending out is oppressed.
