Abstract
The braking control unit for car driving exercise relates to the vehicle braking unit, which belongs to the technical field of car braking. The device adds a pedal-controlled main braking valve to the braking control system; therefore two braking control valves are involved into the system. The control pipe line is linked to the braking control unit through two valves through the parallel connection. The utility model is characterized by the steady performance. If the current valve does not work, the coach can still control and brake the car through the attached control valve and the pedal to ensure the security. Commonality is another characteristic of the device. During the installation of the device the only change to the operator cabin is to add another pedal-controlled braking valve to the floor under the seat of copilot. The pipes are all installed below the floor; no negative impact will be introduced to other components of the operator cabin, therefore the device can be widely used in flat headed or long headed cabs.
Description
(1) technical field
The utility model relates to a kind of brake control device, belongs to automobile brake manipulation technology field.
(2) background technology
At present, the copilot brake control device that driving instructor's car uses, the mode that generally adopts major and minor brake pedal to link together by a connecting rod.This maneuverability pattern is only applicable to normal control vehicle, and concerning cab-over-engine vehicle, because there is the isolation of car bonnet the centre, it is just comparatively complicated to adopt leverage to connect, and also quite difficult to the layout of operator's compartment, has shortcomings such as using inconvenience.
(3) summary of the invention
The utility model is for remedying the deficiencies in the prior art, and a kind of rational in infrastructure, dependable performance, the safe instructional car brake control device that is specially adapted to the cab over automobile are provided.
The utility model is finished by following technical measures.
The utility model is the braking main valve that adds a band pedal control device in the automobile brake operating control with the form of parallel connection, and its pilot piping is connected in parallel by the pipeline of two bilateral check valves and brake control device.
The utility model adds a braking main valve of being with the pedal control device by parallel form, makes whole brake control device form two braking main valves, in the use, is divided into major and minor braking main valve, and the braking main valve of band pedal control device is secondary braking main valve.The utlity model has following advantage: 1, dependable performance, the braking main valve of the band pedal control device that adds and the braking main valve in the existing automobile brake operating control are arranged in parallel, even existing braking main valve et out of order, the coach also can utilize secondary braking main valve to realize braking by the brake activation pedal, thereby has improved the reliability of brake equipment; 2, commonality is good, this device is installed to be changed operator's compartment and only limits to install one directly step on formula braking main valve on the preceding floor of assistant driver seat, pipe section all is positioned at below the floor, does not exert an influence to respectively organizing the part position in the operator's compartment, therefore applicable to multiple tack or conventional cab.

Fig. 2 is the utility model schematic circuit diagram.
Wherein, 1, the main brake main valve, 2, secondary braking main valve, 3, the bilateral check valve, 4, the propons compressed air brake cylinder, 5, the back axle compressed air brake cylinder, 6, relay valve, 7, the back axle air tank, 8, the propons air tank, J, stoplight stop lamp relay, P, open contact.
(5) specific embodiment
Structure as shown in Figure 1, in brake device for car, settle the braking main valve 2 that adds a band pedal control device with the form of parallel connection, form two braking main valves at whole brake control device, in the use, two braking main valves are divided into main brake main valve 1, secondary braking main valve 2, and its pilot piping is connected in parallel by the pipeline of two bilateral check valves 3 with existing brake control device.Principle of work is as follows: the pressurized air of propons air tank 8 and back axle air tank 7 by pipeline respectively to two braking main valve air feed, major and minor braking main valve 1,2 respectively by just be positioned at, the student of copilot station, trainer's control.Two braking main valves 1,2 are all controlled propons compressed air brake cylinder 4 and back axle compressed air brake cylinder 5 by bilateral check valve 3, and shorten braking time by relay valve 6.Therefore, braking effect reaches identical.Fig. 2 has provided the brake operation schematic circuit diagram, when braking main valve 1 or 2 decelerations or brake, and open contact P closure, the work of brake lamp relay J, stoplight stop lamp shows.In the use, under the normal circumstances, the car deceleration braking is by student's control, and when emergency situation, if the student deals with improperly, the trainer can handle the pedal of stepping on secondary braking main valve 2, and automobile is stopped.
Claims (1)
1, a kind of instructional car brake control device, it is characterized in that, add the braking main valve of a band pedal control device in the automobile brake operating control with the form of parallel connection, its pilot piping is connected in parallel by the pipeline of two bilateral check valves and brake control device.
