Abstract
A brake-inflating device for tractor is composed of waste gas leading tube, air stop valve connecting rod and pedal. Because it directly uses the high-pressure gas produced in the exhaust pipe after cut-off as gas-filling source, it can replace the action of air machine for brake. The device has the advantages of simple structure, low cost, quick inflation, strong working reliability, long service life and the like. It is an ideal and practical brake inflator for diesel oil type motor vehicle, especially for small and medium size wheel tractor.
Description
A kind of brake gas filled device belongs to Transport Machinery braking facility.
The brake gear of wheel-tire tractor mainly divides pneumatic and oily moving two big classes both at home and abroad at present.And pneumatically operated brake all is furnished with air engine and will compresses the high pressure air that forms and be stored in the air tank, uses during in order to brake.There is the gas filled device complex structure in it, the cost height, and service life is short, and consumption of power is big, shortcomings such as functional reliability difference and inflationtime length.
The purpose of this utility model is to provide a kind of above not enough brake gas filled device of existing trac. pneumatically operated brake that overcomes.
Technical solution of the present utility model is can be by the air disk (3) of its switch of the foot-operated arbitrarily control in outside by install one in trac. freeing pipe (5), when air disk (3) is closed in utilization, the high pressure gas that produce in freeing pipe (5) back down Non-return air valve ball (6), charge into air tank through waste gas skirt (8) and realize.
The advantage of this device is, owing to directly utilize freeing pipe mesohigh gas inflated, and then replaced air engine.It has cost low (only for air engine 5.7～14.8%), inflationtime short (by 4 minutes of air engine reducing to 15 seconds), characteristics such as functional reliability is strong, and long service life and energy consumption are little.In addition, this device also can be used with original brake gear.
Accompanying drawing is the fundamental diagram of this device
Most preferred embodiment below in conjunction with Figure of description explanation such scheme.
As shown in the figure, when operating wheel-tire tractor need brake, chaufeur was with foot-operated air disk pedal (1), and the transmission by air disk connecting rod (2) is closed air disk (3), and this moment, freeing pipe (5) internal gas pressure increased.When to the pressure of Non-return air valve ball (6) during greater than the elastic force of valve ball spring (7), gas backs down valve ball (6), enters in the air tank (9) through waste gas skirt (8).Approximately through the inflation in 10 seconds, can make to be connected that gas piping (10) is gone up and the indication of the air-pressure gauge (11) that communicates with air tank (9) reaches 3 barometric pressures.Unclamp air disk pedal (1) this moment, and pedal retracing spring (4) is with pedal (1) pop into position.So just finished an inflation procedure.
Claims (1)
1, a kind of wheel-tire tractor brake gas filled device, it is by air disk pedal (1), air disk connecting rod (2), air disk (3) pedal retracing spring (4), freeing pipe (5), Non-return air valve ball (6), valve ball spring (7), waste gas skirt (8), air tank (9), gas piping (10) and air-pressure gauge (11) are formed, it is characterized in that air disk (3) is installed in the freeing pipe (5), and can be by foot-operated air disk pedal (1) outside pipe, through the transmission of air disk connecting rod (2) and the bounce-back of pedal retracing spring, arbitrarily control its switch, the two ends of waste gas skirt (8) communicate with air disk (3) front exhaust pipe and air tank (9) respectively, and Non-return air valve ball (6) and valve ball spring (7) are housed in the waste gas skirt.
