Description
Technical field
The utility model relates to automobile assembling technical field, the slow formula complemental brake system of specifically a kind of exhaust.
Background technique
Closure: be one controllable valve that enters engine for controlling air, enter after suction tude and gasoline mixes (car of different styles, design mixes position difference), become burning mixture, participate in work by combustion.Four-journey petrol engine is roughly all so.Closure is the most important parts of current electric jet vehicle engine system, and his top is air-strainer, and bottom is engine cylinder-body, is the throat of motor car engine.Whether car accelerates flexible, is relative with the clean of closure.
Closure has two kinds of conventional pull wires formula and electronic throttles, and conventional engines throttle control is by drag-line (stone dead wire) or pull bar, and one end connects gas pedal, the other end connecting joint valve interlock plate and working.Electronic throttle, mainly by throttle position sensor, comes according to motor institute energy requirement, controls the opening angle of closure, thus the size of adjusting air inflow quantity.
Since gas handling system has the closure of air inlet, the output of power is controlled in the switching of the closure by air inlet; Equally, we arrange exhaust throttle and should also play braking effect in vent systems.
Summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of exhaust slow formula complemental brake system.
The technical solution of the utility model realizes in the following manner, the slow formula complemental brake system of this exhaust, its structure comprises gas holder and automobile exhaust pipe, gas holder connects steam outlet pipe, on steam outlet pipe, be provided with Unidirectional solenoid valve, steam outlet pipe end connects bounce cylinder, in bounce cylinder, be provided with pneumatic jack piston, pneumatic jack piston connects push rod, push rod front end is fixedly connected with pneumatic jack piston, the upper end portion of one vertical pole offers fraising, underpart offers lower fraising, middle part is provided with fixed rotating shaft, push rod afterbody is hinged in the upper fraising of vertical pole, the lower fraising of vertical pole is hinged with pull bar, push rod end is provided with reset top spring, pull bar end is provided with hinge, stud connection one connecting rod, in automobile exhaust pipe, be provided with exhaust throttle, connecting rod end is connected with the exhaust throttle in automobile exhaust pipe.
On bounce cylinder, be provided with overvoltage gas bleeder valve.
The beneficial effect that the utility model compared with prior art produced is:
The basic functional principle of the slow formula complemental brake system of this exhaust is to utilize the switching that is arranged on the exhaust throttle in automobile exhaust pipe exhaust passage to block engine exhaust passage, to increase the power loss of the strokes such as air inlet in motor, exhaust, compression, force motor to reduce rotating speed, thereby reach the object that reduces at short notice the speed of a motor vehicle.
The slow formula complemental brake system of this exhaust is particularly useful for applying exhaust brake on large-scale cargo vehicle, and its pressure is high, and braking effect is obvious, does not need other medium, with low cost, slow reduction of speed good braking effect.
The slow formula complemental brake system of this exhaust is reasonable in design, simple in structure, safe and reliable, easy to use, be easy to safeguard, has good value for applications.
