Abstract
The utility model relates to an auxiliary brake belongs to vehicle braking technology field, and it includes PMKD, lifter plate and pneumatic cylinder, wherein PMKD is fixed sets up in the bottom of vehicle, the one end of lifter plate articulates on PMKD, is provided with the drag friction piece on the other end, pneumatic cylinder one end articulate in vehicle bottom, the other end articulates in the lifter plate, trigger the pneumatic cylinder switch during proruption road conditions emergency braking, make drag friction piece and ground friction provide extra frictional force, the beneficial effects are that: a braking distance that the extra frictional force of shortens the vehicle is provided.
Description
Technical field
The utility model belongs to Vehicular brake device field, especially relates to a kind of auxiliary brake.
Background technology
Current car brakeing is mainly drum brake mechanism and plate disc brake, and its principle allows to slow down even stop motion with the brake hub of tire High Rotation Speed or brake disc, in order to reach the object of shorter braking distance, tire is allowed to be in locking or zero boundary's state, that current industry is to the common method controlling braking distance, that is the braking distance of a car, in the ideal situation, suppose that brake system is excellent, can locking tire under any state, so its principal element depends on the friction force between vehicle and ground, and now the size of friction force only depends on the size of the friction coefficient between tire and ground, no matter how people improve tire and brake system, all there is a theoretical extreme in a car its friction force under various pavement conditions, to help without him.When being in an emergency, more fully loaded lorry, because inertia is huge, its braking force often can not by tire locking, and emergency braking in this case, will make braking distance elongated, just easily causes uncertain accident.
Utility model content
Problem to be solved in the utility model is: the friction force increasing vehicle and ground.
In order to achieve the above object, scheme of the present utility model is: provide a kind of auxiliary brake, comprises fixed base plate, lifter plate and hydraulic actuating cylinder; Fixed base plate is fixedly installed on the bottom of vehicle; Described lifter plate one end is articulated with on fixed base plate, the other end is provided with drag friction block; Hydraulic actuating cylinder one end is articulated with vehicle bottom simultaneously, and the other end is articulated with on lifter plate, under normal motoring condition, is packed up by lifter plate, makes drag friction block friction shoe not contact bottom surface, keeps the normal traveling of vehicle; When meeting emergency case on the way, when needing emergency braking, except brake system brakes, trigger hydraulic actuating cylinder starting switch simultaneously, hydraulic cylinder piston is released, promote lifter plate one end and earth surface, make drag friction block and ground friction, produce additional friction, thus make the friction force adding vehicle and ground, shorten braking distance.
Further, for the ease of controlling, hydraulic actuating cylinder adopts telescoping hydraulic cylinder.
Further, in order to be optimize structure, lifter plate and hydraulic actuating cylinder are articulated with on the first hinged seat, and this first hinged seat is fixedly installed on the middle part of lifter plate.
Further, for the ease of installing, hydraulic actuating cylinder is fixedly connected on the bottom of vehicle by the second hinged seat.
The beneficial effects of the utility model are: provide extra friction force to vehicle, shorten the braking distance of vehicle.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present utility model;
Fig. 2 is exploded view of the present utility model.
In figure: fixed base plate (1), lifter plate (2), hydraulic actuating cylinder (3), drag friction block (21), the first hinged seat (22), the second hinged seat (31).
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of auxiliary brake, comprises fixed base plate 1, lifter plate 2 and hydraulic actuating cylinder 3; Wherein fixed base plate 1 is fixedly installed on the bottom of vehicle; Lifter plate 2 one end is articulated with on fixed base plate 1, the other end is provided with drag friction block 21; Hydraulic actuating cylinder 3 one end is articulated with vehicle bottom, preferably, this hydraulic actuating cylinder 3 can be selected as telescoping hydraulic cylinder, and the other end of hydraulic actuating cylinder 3 is articulated with lifter plate 2, lifter plate 2 and hydraulic actuating cylinder 3 are articulated with on the first hinged seat 22, and the first hinged seat 22 is fixedly installed on the middle part of lifter plate 2.
Hydraulic actuating cylinder 3 is fixedly connected on the bottom of vehicle by the second hinged seat 31, and wherein the second hinged seat 31 is fixedly installed in the bottom of vehicle.Under normal motoring condition, lifter plate 2 is packed up, make drag friction block friction shoe 21 not contact bottom surface, keep the normal traveling of vehicle; When meeting emergency case on the way, when needing emergency braking, except brake system brakes, trigger hydraulic actuating cylinder 3 starting switch simultaneously, the piston of hydraulic actuating cylinder 3 is released, promote one end and the earth surface of lifter plate 2, make drag friction block 21 and ground friction, produce additional friction, thus make the friction force adding vehicle and ground, shorten braking distance.
