In sum, be not difficult to find out, the horizontal sliding double-sided braking retarder actuating unit that above embodiment provides, on the basis at existing inner supporting type stop mechanism, set up the braking rail of extrapolation outward in stock rail, realize inside and outside both sides and push extruding, realize the braking to vehicle, and the brake cylinder of inside and outside braking rail is independent, does not interfere with each other, improve double effects and the reliability of braking.
The utlity model has braking by grades function, be now described below:
Braking, alleviate working process and mode: before vehicle enters retarder, horizontal sliding double-sided braking retarder actuating unit is in retarder location, i.e. initial position.Vehicle enters after retarder track circuit, if group's car, executive device keeps this invariant position, when vehicle enters after flat push type executive device, and extruding braking rail, braking rail reacts on wheel, and wheel is applied to braking force, and the speed of vehicle is lowered.To organize greatly car if enter the vehicle of retarder track circuit, at this moment executive device is at large tank (two-way cylinder 4) and small oil tank (left outside brake cylinder 19, right outside brake cylinder 20) drive under, move to and alleviate position by braking position, vehicle moves ahead with certain speed, carry out " put head and block tail ", flat push type inner support vehicle reducer-actuating unit is not implemented braking to former cars, when reaching, the head amount of putting controls while requiring, control system order flat push type inner support vehicle reducer-actuating unit moves to working position, vehicle is implemented to braking, until speed reaches control requirement.At this moment control system command execution device moves to release position, and vehicle passes through executive device smoothly.
Repeat the realization of braking function: be the group car of growing up in fact if enter the vehicle of horizontal sliding double-sided braking retarder actuating unit, alleviate reaching executive device after constant speed, but due to circuit or the acceleration of wind-force reason, when car speed exceedes constant speed, at this moment need to repeat braking, at this moment as long as issue an order on controlling, horizontal sliding double-sided braking retarder actuating unit can move to working position from retarder location rapidly, and vehicle is implemented to repeat braking.Make the speed of vehicle again drop to constant speed value, complete after repetition braking function, then move to alleviation position.
The conversion of braking grade: if horizontal sliding double-sided braking retarder actuating unit is used in conjunction with multistage or stepless speed reducer hydraulic control system, when braking, brake the conversion of grade, the invariant position that executive device is in, just the pressure size in large tank and small oil tank can need to change according to controlling, owing to there is no translation stroke, there is not mechanical movement, therefore braking grade conversion is only the break-make response time of electric elements, reacting phase is when rapidly, at several Milliseconds.Therefore adjusting speed accuracy is high, is applicable to modulated braking.
Positional representation: in horizontal sliding double-sided braking retarder actuating unit working process, after putting in place with alleviation after the braking of horizontal sliding double-sided braking retarder actuating unit puts in place, by representing the approach switch work in assembly, automatically braking work state information is presented on job control platform.
