In utilizing the force of inertia braking technology, the still rail vehicle of most worthy is at the high-speed overload car team or do not having in the car team, vehicle braked in outer braking force source all the more so.But, in the present mine car row of China, vehicle except that hauling engine does not have the braking force source mostly, the existing patent of finding " dead-man's device of mine car " (seeing Chinese utility model patent CN87203839U international classification number B61H11/02), it is after beginning to execute the external force braking deceleration by hauling engine, the force of inertia that could utilize the prosthomere vehicle is to back one joint vehicle slowing-down brake successively, but can not make every joint vehicle utilize its own inertial power to consume as braking force separately separately, make whole car team apply brake simultaneously, to realize the braking of short distance more fast.
The objective of the invention is to, realize a kind of inertia automatic braking of vehicle and equipment, quick, energy-conservation, simply constructed brake equipment of utilizing.
Below in conjunction with accompanying drawing this device is described:
Accompanying drawing 1 is the utility model specific embodiment 1 scheme drawing.
Accompanying drawing 2 is the utility model specific embodiment 2 scheme drawings.
Accompanying drawing 3 is friction braking element scheme drawings.
From accompanying drawing 1, as can be seen, on two axletrees of a vehicle, adorn inherent gear 1 and 5, install two axles in the middle of two axletrees in addition additional, on one of them axle transmission gear 2 is housed, on another axle that installs additional gear 3 and 4 are arranged, gear 3 and gear 5 engagements, gear 4 and gear 2 and 1 engagement.Rightabout rotation is done in the positive and negative transmission that is subjected to gear 1 and 5 owing to gear 3 and 4, and dress is solid on friction braking mechanism member 6 and 7 respectively.Friction element bearing 14(Fig. 3 on the solid axle between 6 and 7 of dress) have two opposed a braking element 15 to be arranged above, the friction element of this heat-resistant antifriction can be the oval brake shoe brake cheek of a kind of bearing opposed type, fully by power operated control.
When normal vehicle operation, stop mechanism 6 and 7 is in complete released state, controls the friction element rotational angle when glancing impact by control link, makes 6 and 7 to produce friction, the mutual resistance owing to make backward rotation, and the force of inertia of vehicle mutually offsets and brakes.
This device can also be following content:
In accompanying drawing 1, this friction braking element also can be positioned on centrifugal control mechanism on the axletree by dress, by the speed of a motor vehicle and force of inertia to its automatically regulating control.It is vertical little with having between centrifugal pendulum (end shows among the figure) pendulum that changes and axletree with axletree that but friction braking mechanism one side is equipped with two centrifugal swings on the axletree of dress inherent gear 5.When vehicle reached certain speed, centrifugal pendulum rotation pendulum is lifted, and was vertical with axletree, by connecting rod drawing friction braking element, realizes self-actuating brake.When vehicle was lower than certain speed or stops, centrifugal pendulum was parallel with axletree, stretchy connecting rod not, and braking action does not take place in braking element.This device is when wheel slides, because of centrifugal pendulum can not be put the automatic guidance effect that loses of lifting.
In braking technology, braking element is wanted afterburning vehicle in braking, its inertia is resisted the burden of braking strenuously, can influence the effect of braking element control brake, in this device, with gear with force of inertia reverse drive own after, directly reclaim to use, force of inertia and brake weight are directly linked, brake weight can be asked for as required, and the friction braking element is not born the brake power, and special control brake degree is laborsaving sensitivity, but standard is handled again, realize the braking of force of inertia, just can make full use of the adhesion between the wheel track, obtained short as far as possible stopping distance, in the car team braking, because vehicle is the own force of inertia braking of use separately all, can improve braking propagation rate, saves the braking force energy resource consumption, the enforcement of this kind method is simple in structure, and retrofit application on the existing design basis suits.
