Description
Technical field
The utility model belongs to Vehicle Engineering technical field of engines, relates to the changeable air valve of electrichydraulic control.
Background technique
Along with expanding economy, transportation development is rapid; Transport vehicle is mostly large-scale diesel-engine road vehicle, because the cargo mass of vehicle in transportation process is larger, therefore needs larger braking force; And the easy heating of the drum brake of large vehicle assembling causes braking ability to decline, driver can carry out auxiliary braking with the braking of motor, due to the power limited of engine braking, therefore needs a kind of complemental brake system.
Model utility content
The utility model, in order to make up above-mentioned deficiency, provides a kind of changeable air valve due to auxiliary braking.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of changeable air valve for auxiliary braking, it is characterized in that: comprise camshaft (6), valve (1), valve rocker (2), push rod assembly (3), fluid power control assembly (4), hydraulic tappet (5) and hydraulic connecting pipeline, described fluid power control assembly comprises two-position three way hydrovalve (7), accumulator, fuel tank.Magnetic switch (8) and relief valve.Described hydraulic tappet is provided with oil inlet passage, drainback passage and piston.Described push rod assembly drives pushrod movement to control hydraulic tappet to realize the control of valve lift by being arranged on camshaft in cylinder head.
As preferred technological scheme, described hydraulic tappet (5) is realized the lift of valve by be connected the position of control hydraulic tappet inner carrier with fluid power control assembly (4).
As preferred technological scheme, the joint of described hydraulic connecting pipeline uses metallic material, and pipeline uses flexible pipe.
As preferred technological scheme, described fluid power control assembly (4) carrys out the oil pressure of control system by magnetic switch.
As preferred technological scheme, described push rod assembly (3) one end is connected with camshaft, and centre is provided with hydraulic tappet, and the other end is connected with valve rocker.
The disclosed changeable air valve for auxiliary braking of the utility model, its advantage is: reasonable in design, simple in structure, can continuous control for the timing of valve and lift, improve the Security of driving and also discharging pollutants of motor reasonably controlled simultaneously.
