Abstract
The invention discloses an aluminum alloy braking system for a semi-trailer. The braking system comprises a brake pedal, an emergency relay valve, a trailer hand valve, a tractor gas reservoir, a trailer gas reservoir and a brake chamber, wherein the emergency relay valve is connected with the tractor gas reservoir and the trailer gas reservoir through the trailer hand valve; gas enters the trailer gas reservoir and the tractor gas reservoir through a gas path; when the brake pedal is stepped down, compressed air enters a trailer operation pipeline through a trailer brake valve on the tractor, passes through the emergency relay valve, and opens the valve; gas enters the brake chamber, so that a piston of the brake chamber is pushed to a brake position, and brake is realized; when the brake pedal is released, gas in the gas chamber is exhausted through a quick release valve, a brake piston is recovered to a non-brake position under the action of a return spring, and brake is released. According to the braking system disclosed by the invention, when the braking system performs emergency brake, the maneuverability of the direction of the trailer is maintained.
Description
Technical field
The present invention relates to special-use vehicle manufacturing technology field, especially a kind of aluminum alloy semitrailer brake system being controlled brake by air pressure.
Background technology
Along with the development of China Special Vehicle industry and the support energetically of national policy, aluminum alloy superimposed trailer sales volume is in the period that increases substantially, and in the face of this present situation, brings all urgent problems thereupon.Time unloaded, Trailer axle quality is light, and easily drag dead, slow down unreasonable, wear on tyres is serious, thus causes the spirit or ineffective of braking.Load-carrying is trailer quality weight, slows down undesirable, and braking distance increases, thus safety can not be effectively guaranteed.
Summary of the invention
The present invention controls the aluminum alloy semitrailer brake system of brake by air pressure, and it can solve and make the automobile in traveling carry out forced deceleration according to the requirement of chaufeur even to stop; The automobile of stagnation of movement is made (to be included on ramp) steadily halt under different kinds of roads condition; The car speed of descent run is made to keep stable.
Technical scheme of the present invention is: a kind of aluminum alloy semitrailer brake system, comprise brake pedal, emergency relay valve, trailer hand shaking valve, tractor truck air receiver, trailer air receiver and compressed air brake cylinder, described emergency relay valve is connected with tractor truck air receiver and trailer air receiver by trailer hand shaking valve, and gas enters trailer air receiver and tractor truck air receiver through gas circuit; Step on brake pedal, the trailer braking valve of pressurized air on tractor truck enters trailer pilot line, and by emergency brake valve, back down valve, gas enters compressed air brake cylinder, the piston of compressed air brake cylinder is shifted onto braking position and realizes braking; Loosen the brake, the gas of compressed air brake cylinder is exitted by rapid release valve, and brake piston is returned to not braking position under pull back spring effect, brake release.
Preferably, described compressed air brake cylinder comprises single cavity gas chamber and two-chamber air chamber.
Preferably, the high pressure gas in described tractor truck air receiver and trailer air receiver are entered by trailer driven by engine air pump compresses.
Preferably, state gas to be controlled by ABS regulating control.
Beneficial effect of the present invention:
1, the operability in the direction of trailer vehicles is maintained when emergency braking;
2, effectively shorten stopping distance, make braking continuous, reliable, ensure that the safety traffic of vehicle;
3, when tractor truck thrown off by trailer, brake piping cuts off; Or in emergency circumstances trailer pipeline generation fracture damage, trailer brake system autobrake, ensures safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of aluminum alloy semitrailer brake system of the present invention;
In figure: 1 trailer hand shaking valve, 2 emergency relay valve, 3 air receivers, 4ABS regulating control, 5 two-chamber air chambers, 6 rapid release valves.
Detailed description of the invention
By reference to the accompanying drawings embodiment provided by the invention is described in further detail:
As shown in Figure 1, a kind of aluminum alloy semitrailer brake system, comprise brake pedal, emergency relay valve 2, trailer hand shaking valve 1, air receiver 3 and compressed air brake cylinder, described air receiver comprises trailer air receiver and tractor truck air receiver, described emergency relay valve 2 is connected with tractor truck air receiver and trailer air receiver by trailer hand shaking valve 1, and gas enters trailer air receiver and tractor truck air receiver through gas circuit; Step on brake pedal, the trailer braking valve of pressurized air on tractor truck enters trailer pilot line, and by emergency brake valve, back down valve, gas enters compressed air brake cylinder, the piston of compressed air brake cylinder is shifted onto braking position and realizes braking; Loosen the brake, the gas of compressed air brake cylinder is exitted by rapid release valve 6, and brake piston is returned to not braking position under pull back spring effect, brake release.
Preferably, described compressed air brake cylinder comprises single cavity gas chamber and two-chamber air chamber 5.
Preferably, the high pressure gas in described tractor truck air receiver and trailer air receiver are entered by trailer driven by engine air pump compresses.
Preferably, described gas is controlled by ABS regulating control 4.
Concrete braking procedure:
When to traveling train braking, step on brake pedal, the trailer braking valve of pressurized air on tractor truck enters trailer pilot line, by emergency brake valve, back down valve, gas enters compressed air brake cylinder, shift the brake piston of the diaphragm of single cavity gas chamber and two-chamber air chamber onto braking position, push rod is released, pulls braking adjusting arm, drive cam axle and realize service brake.When brake off, loosen the brake, the gas of single cavity gas chamber and the service brake of two-chamber air chamber is exitted by rapid release valve, single cavity gas chamber's diaphragm and two-chamber air chamber brake piston are returned to not braking position under pull back spring effect, but the missing braking during standstill chamber to two-chamber air chamber of trailer air receiver pressurized air is filled with, compressed energy-storage spring is that braking during standstill piston is in not braking position, brake release.When driving a vehicle braking failure, during as needed emergency braking in driving conditions, can anxious spanner control cock, exit in air chamber braking during standstill chamber, energy stroage spring is upheld immediately and two brake pistons is all shifted onto braking position, realizes braking.
In this description, the present invention is described with reference to its specific embodiment.But, still can make various amendment and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification sheets and accompanying drawing are regarded in an illustrative, rather than a restrictive.
