It now brakes, alleviates.
The working principle of the car retarder of the present embodiment is as follows: vehicle reducer-actuating unit when not working usually at
In retarder location.After the vehicle to get off on hump enters reducer track circuit, after control system issues order as needed, in liquid
Under the action of pressure system, which starts to work, if implementing to brake to vehicle, executing agency
Under the action of plunger cylinder, the overhanging clamp body that lifts of plunger 3 swings rise, and two braking rails are in retarder location working condition, this
When two braking rail opening sizes be less than wheel thickness.When vehicle enters retarder, wheel squeezes braking rail, plunger cylinder pressure
It increases, vehicle is implemented to brake, prevent vehicle forward, the speed decline of vehicle.When car speed, which reaches control, to be required, control
System issues alleviation order, and the pressure release discharge rapidly of the oil in plunger cylinder, 3 clamp body of plunger and braking rail are fast under the effect of gravity
Speed decline moves to alleviating position together, and vehicle passes through.
The course of work and mode are alleviated in braking: before vehicle enters reducer actuator, control system issues braking life
After order, vehicle reducer-actuating unit is in original braking operation position.After vehicle enters reducer actuator, if it is small
Group vehicle, executive device can keep this position constant, and after vehicle enters reducer actuator, wheel squeezes braking rail, braking rail
Wheel is reacted on, brake force is applied to wheel, realizes and slows down.If the vehicle into reducer actuator be in, big group
Vehicle is carried out " put head and block tail "；Vehicle is moved ahead with certain speed, and reducer actuator wouldn't carry out braking to former vehicles,
When putting head amount, which reaches control, to be required, control system order reducer actuator moves to original working position, implements to vehicle
Braking, until speed reaches control and requires, at this moment control system order executive device, which moves to, alleviates operating position, and vehicle is smooth
Pass through reducer actuator.
It repeats braking function to realize: if being a group vehicle of growing up into reducer actuator, dress is executed after reaching constant speed
It sets and has alleviated, but accelerate due to route or wind-force etc., when car speed is more than constant speed, at this moment need to implement to repeat to make
It is dynamic；As long as control command provides, this vehicle reducer-actuating unit will reach braking operation position from alleviation working position rapidly, right
Vehicle is implemented to repeat to brake, and the speed of vehicle is made to drop to fixed speed again, completes to repeat braking function.
The conversion of brake force: this executive device and hydra-electric system cooperation are, it can be achieved that brake force grade is converted.Work as braking
When power order of magnitude is converted, the machine performance of executive device is constant, and only Plunger oil in-cylinder pressure size is according to control command need
It changes.Since mechanical movement does not occur, the conversion time of brake rating is the electric elements on-off response time, anti-
Should quite rapidly, therefore this executive device speed regulation accuracy is higher.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
