Abstract
The utility model relates to an anti-skid device for braking. A back vehicle frame body provided with a chain-typed anti-skid hoof is provided with a jaw plate, and the corresponding position of the synchronizing shaft plate of the chain-typed anti-skid hoof is provided with a restoring plate which is provided with oval front end and can be held into a jaw opening. The restoring plate is indexed by a steel cable, and a reel which winds the steel cable is towed by a motor arranged on the vehicle frame body. The utility model can completely avoids accidents due to inefficient hard braking when buses drive on the road surfaces full of snow and ice, and rain water.
Description
The utility model provides a kind of " brake anti-skid device ", is particularly suitable for motorcoach and makes emergency brake usefulness, belongs to the drg technology in the communications and transportation.
At present, prevent during brake that car body from breakking away, thereby avoid the technology of causing trouble more.Chinese patent discloses a kind of accident brake No. 90219480.1.This drg turn the axle one end hinged by universal coupling and curved bar, stretch to an other end that turns of tire surface, be connected with skidproof hoof; Curved bar is hinged on reciprocation type vacuum pump piston rod end; Reciprocation type vacuum pump and car back frame body support are hinged, and two air extractor vents of pump are connected with the driving engine aspirate tube.Be located at " drawing wushu " third gear switch in the operator's compartment by manipulation, decision comes and goes the mode of operation of vacuum pump two ends threeway magnetic valve, and then the stroke of control vacuum pump piston rod, and the position of final decision skidproof hoof.This accident brake, its skidproof hoof and ground-surface friction resistance can be realized the moment parking of car body, and can avoid car body to break away.Not enough is the accident brake of this structure, because reciprocation type vacuum pump volume is bigger, can't be applied in the small-sized car body.Chinese patent 91210635.2 discloses a kind of dead-weight accident brake.This drg adopts at the car back frame body rotating machine that twines the steel rope that is connected with curved bar on its reel is set, one end buckle also is set buckles the curved bar latch hook, the other end is controlled by the rotation locking bar of magnetic valve, and in the upright position of the corresponding curved bar of car back frame body technical schemes such as magnetic valve cut-off switch is set.The dead-weight accident brake is particularly suitable for wagon and uses.But 90219480.1 and No. 91210635.2 patented technologies all can not be made the motor omnibus accident brake and use.
The purpose of this utility model provides the brake anti-skid device that a kind of suitable motorcoach emergency braking is used.
The purpose of this utility model realizes by following technical measures.
On the back vehicle frame that is equipped with the chain type skidproof hoof, jaw is set, moving jaw except that be fixed on the deciding the jaw root is hinged of vehicle frame, overhanging end also is hinged with the branch air pump output shaft that is arranged on the vehicle frame at the bottom of its jaw; The synchronous axillare correspondence position setting of chain type skidproof hoof can be held in the mouth the jaw mouth, has the playback plate of avette front end, and this playback plate is by the steel rope index, and the reel of lay winding wire ropes is dragged by the motor that is arranged on vehicle frame.
Be arranged on the pressure work that the branch air pump on the vehicle frame utilizes this car Air compressor to produce.Baroswitch is arranged in the operator's compartment, special-purpose gas path pipe is set leads to the branch air pump.When the needs emergency braking or on ice and snow road, implement glancing impact, press baroswitch, make the work of branch air pump, divide the overhanging output shaft of air pump to move, the rotation of pivotally attached moving jaw plate, the jaw mouth opens, and rank is advanced the playback front edge of board of jaw mouth and deviate from, and the chain type skidproof hoof falls to landing because of deadweight, the tire that is moved ahead rolls, when the skidproof hoof chain was straightened, vehicle just stopped to travel, and implemented the emergency braking that can not break away.When needs skidproof hoof rising return, start the motor haulage cable, drag the playback plate and go upward to the jaw mouth, after being held in the mouth, just can normally start vehicle.
The brake anti-skid device, owing to possess the dragging motor that divides air pump independently and promote skidproof hoof, configuration can be held in the mouth the jaw of tight skidproof hoof playback plate, it is reliable to have emergency brake, be fit to the characteristics that motorcoach uses, can avoid the accident that takes place because of sudden stop is ineffective during the rainwater road traveling fully at ice and snow.
Accompanying drawing 1 is the structural representation of brake anti-skid device, and accompanying drawing 2 is birds-eye vieies of brake anti-skid device.Below in conjunction with accompanying drawing,, further narrate its technical characterictic by most preferred embodiment.
The brake anti-skid device, by the chain type skidproof hoof (1) that is arranged on aftercarriage, moving jaw plate (11) and decide the movable jaw that jaw (12) constitutes, can be advanced the jaw mouth by rank in the correspondence position setting of the synchronous axillare (14) of chain type skidproof hoof (1), have the playback plate (2) of avette front end, bind the haulage cable (8) of playback plate (2), guide wheel (9), be arranged on the independent air pump (10) that divides of back vehicle frame, motor (13) is formed.
Moving jaw plate (11) with decide outside jaw (12) cuts with scissors mutually, its jaw root overhanging end also cuts with scissors mutually with branch air pump (10) output shaft that is arranged on the vehicle frame.Two overhanging ends of rotating shaft (15) are provided with the rolling wheel of lay winding wire ropes (8) cantilever.Sprocket wheel (14) is set in the rotating shaft (15), and motor (13) output shaft upper sprocket wheel is formed chain wheel driving mechanism.
In the present embodiment, the upper end of chain type skidproof hoof is an adjusting shaft, pass the bearing seat (5) that is fixed on vehicle frame after, have swelling spring (6) then by nut (7) tightening.(3) be tire, (4) are double strand chain.
Claims (1)
