Description

[Detailed Description of the Invention] The present invention supplements the shortage of electrical braking (hereinafter referred to as electric braking) force with respect to the commanded braking force of one formation of military vehicles using a fluid braking force. The present invention relates to a 'eK air command type fluid brake device.

In general, a delay system of fluid brake system +1 (delay system) that operates a fluid brake to supplement the insufficient electrical braking force in a train consisting of a motor TL (hereinafter referred to as an M vehicle) and a trailer vehicle (hereinafter referred to as a T vehicle). is M when the composition brake command voltage is less than the maximum adhesive brake force equivalent voltage of M cars.
When a car exerts the entire braking force of the train set and the train set brake command voltage is equal to or higher than the maximum adhesive braking force equivalent voltage of M and fj, the M car maintains the maximum adhesion brake force and the T car bears the shortfall. It is a system that makes maximum use of the M vehicle's power.

However, the above-mentioned general fluid brake device has 1 overhead line overvoltage or 9. regeneration. 't? When the electric brake is disabled due to load, etc., all of the train braking force is borne by the hydraulic brake force, and the M car uses the electric brake force → the current brake force.

Since the T car will bear the 721 body brake force of the shortage, the amount of fluid brake force to be borne by the M car and the T car will be 11J, excluding the vicinity of the maximum brake command, and the brake shoe of the M car will be different. The glue φ was more severe than that of the T car, and there was a problem with the maintenance of the brake shoes of the M car and the T car.

For this reason, as disclosed in Japanese Patent Application Laid-open No. 56-110404, when the electric control system is in effect, the electric control power of the M car is utilized to the maximum, and when the electric control system is invalidated, the electric control power of the M car and the T car are each provided with city power. allocated vt
An electrically commanded fluid brake shoe has been proposed that causes a rake on the shaking body of the fi body, and this conventional device will be explained based on Fig. 1. In Fig. 1, 1 m is an M car, and It is a T It is a car, and these are the valley's air-fluid pressure change valve 1, k valve 1B, relay valve 14.
A brake cylinder 15 is provided.

The 1·11+1 brake command 'Fli pressure' from the brake command unit 2 is transmitted to the 'ItLi+jlJ command unit 3, and the command unit 3 has a limiter characteristic. In other words, the formation brake command 'Tonnage pressure F or M car 1m slope large viscous brake shoe' [when ij pressure is 11 or less]
The output E of the electric control controller 3 is (E=F), and when the formation brake command 'rii and the pressure F are I (or more), the electric control controller 3

In the following cases, the temporary 'R vehicle negative 411 fluid brake command city pressure is set as the true T vehicle burden fluid brake pressure (1st order'tonne pressure'), and the temporary M vehicle negative fluid brake command The tonnage pressure is set to the true MIIi negative 411 fluid brake command pressure, and the temporary fluid brake command 'Gi pressure borne by the T vehicle is set up, and the one-kid command pressure F is set to the T vehicle pressure -η1, and the distributed CF-

The hydraulic brake is activated at each time.

The above negative sum fluid brake command voltage for each vehicle can be seen as the equivalent fluid brake force (deceleration due to fluid brake force).
A relationship exists: = (fluid brake force)/(weight).

Therefore, the deceleration βm due to the fluid brake of 1 m vehicle M and the deceleration βt due to the fluid brake 1 m vehicle IT are each as follows: I! Become one.

First, the brake command pressure F is M jl

=F), the output of the second arithmetic unit 7 is ((F - G
)・1゛/(sr+T)), and the output of the T single thrower 8 is CF-T/(M+T)), so the output of the diode 10 is always zero. Therefore, βm
=βt-4(FG)/(M+r)).

In addition, when the wheel forming brake fluid command voltage F exceeds the pressure H for the large viscous brake fluid for M vehicles, the output E of the one wheel jl+lj command unit 3 is (E=H), and at this time, One turn of deceleration of each car will result in the following 'lT1ji'.

(1) If the above-mentioned losing T car negative J, li fluid brake command voltage is less than 1゛ car weight distribution of the formation brake command voltage F, that is, if G≧(F-H)・M / T, βt
=(H-G)/(M+T)+(F-H)/1"βm=(
H - G)/(M + T) In this case, since F>H, the relationship βt>βm always holds, and the carpet movement βt due to 1 t CD fluid brake of T car is due to 1 m fluid brake of M car. It is larger than the deceleration βm.

(10 The fluid brake command borne by the losing T vehicle mentioned above has a pressure of Ml.

As described above, the car brake command type v;C body brake system of the present invention applies electric braking force when the formation brake command 'tonne pressure F exceeds the city pressure H for one turn, such as the maximum viscosity brake force of M cars. As long as it does not become zero even if it decreases, the deceleration βt due to the fluid brake of 1 ton of T car is equal to the deceleration β due to 1 m of fluid brake of M car
Since it is larger than m and (T East model weight < (M ton plate weight), Mli of 1 t of T car, body brake force and bI of 1 m of M
The difference between the C-body brake force and the C-body brake force can be made smaller than that of conventional devices.

It has the characteristic of reducing the torque when running, and reducing the force when running.

Here, when the brake command voltage F exceeds the Mh maximum adhesion brake force equivalent voltage H, the combined deceleration βM of M vehicles of the conventional device if and the device of the present invention, that is, M-1
When considering the deceleration due to 1 t of fluid braking force and the deceleration due to electric braking force, these are as follows.

T) In other words, when the formation brake command box pressure F exceeds the maximum adhesion brake force equivalent voltage H, the conventional device detects that even if the electric braking force G decreases, if the amount of decrease is small, the M car composite deceleration lever β
M maintains a constant value (H/M), and the M vehicle composite deceleration βM decreases only when the reduction JjF of the electric force G reaches a certain 1' or more.

On the other hand, in the device of the present invention, when (F>H), as soon as the electric braking force G begins to drop by 1 degree, the M car composite deceleration βM decreases, and the amount of decrease in the electric braking force G is equal to or greater than the value. Then, the M vehicle composite deceleration βM becomes a constant value [F/(M+T)).

Therefore, if the conventional device and the device of the present invention are respectively used excessively, and the wheels skid while the formation brake command voltage F exceeds the maximum adhesion brake pressure H, the above-mentioned problem will occur. The torque of the road guidance IT motive decreases and the city side force G decreases, but in the case of the conventional device, if the low T name of the city 1UIJ force G is small, the M car attachment force decreases, that is, the M car composite braking force decreases. To maintain a constant value, early readhesion between wheel and rail is not possible. However, in the case of the device of the present invention, when the side force G starts to decrease at '1, the M car composite deceleration degree, that is, the M car composite brake force, immediately decreases, so early adhesion between the wheels and the rails is possible.
