Abstract

The invention relates to a transport engineering, in particular to devices for controlling the brakes of vehicles, such as a cargo trailer and a mini-tractor. The purpose of the invention is to improve the reliability of braking in the hundred-night position. In the brake control actuator there is a pedal lever 1 with a traction element, a control cable and an axis on which a clamp 6, which is made in the form of a plate, is spring-loaded over the gear sector 5. A clamping element is installed above the retainer 6 on the axis 4, made in the form of a flag 7 with the lower edge 8, the trajectory 9 of which rotation is located in the plane 10 forming an acute angle α with the retainer plate 6. 3 Il.

Description

The invention relates to a transport engineering, namely to devices for controlling the brakes of vehicles, for example, a trailer truck attached to a mini-tractor-RU.

The aim of the invention is to improve the reliability of braking in the standing position.

FIG. Figure 1 shows the drive control of the brakes of the semi-trailer in the overnight position; in fig. 2 is a view A of FIG. one; FIG 3 is a view B in FIG. 2

The drive control of the brakes of the semi-trailer contains a pedal lever 1 with a traction element 2, a control cable 3 and an axis 4. On axis 4 above the toothed sector 5, the spring 6 is spring-loaded and is normally open and self-releasing when it is braked. The latch 6 is complete in the form of a plate. A clamping element is installed above the retainer 6 on the axis 4, made in the form of a flag 7 with the lower edge 8 and rotatably around another axis. The trajectory 9 of the turn of the rib 8 is located in the plane 10, forming an acute angle with the clamp plate 6.

The drive works as follows.

Working braking by applying force P to the lever pedal 1. In this case, the pedal lever 1, turning on the axis, moves the traction element 2 and the control cable 3 acting on the braking devices 10

A hundred-night braking is carried out by applying force P to the pedal lever 1, inserting the latch plate 6 into one of the depressions between the teeth of sector 5 and pressing the lower edge 8 of the clamping element 7 flag to the latch plate by turning the flag "Loosening the night-time braking is performed by turning the flag 7 in the opposite direction until it leaves the contact with the latch plate 6 and the last of the depression between the teeth of the sector 5 from the spring force.
