(54) VEHICLE MANAGEMENT DEVICE

one

FIELD OF THE INVENTION The invention relates to vehicle engineering, in particular, to vehicle control devices.

A vehicle control device comprising a hydraulically operated chassis pedal mechanism, having a forward pedal and a reverse pedal pedal mounted in opposite directions with an intermediate shaft of said mechanism, and a vehicle speed range switching mechanism, are known. the inclusion of the transport range, the scenes of the inclusion of the working ranges of the control center, installed with the possibility of selective Interactions with the scenes 1.

The disadvantage of the device is that it limits the transport speed with a corresponding limitation of working speeds, which does not allow to set the optimum working speed of the machine, and does not exclude reverse gear when driving in transport mode.

The purpose of the invention is to increase the reliability of driving a vehicle. The goal is achieved by the fact that the device is equipped with a safety mechanism, made in the form of a pull rod with a stop, one end of which is pivotally connected to the connecting section of the transport range and having on the other end a longitudinal groove in which the slider is connected, which is connected to said intermediate wa, Q scrap made with a protrusion for interacting with the stop thrust in the transport mode of motion.

FIG. 1 shows a device with a span of a range switching mechanism and a hydraulic control pedal running

15 parts in neutral position; in fig. 2 - the same, with the included link of the transport range and the hydraulic control pedal in the forward position; in fig. 3 - the same, with the included link of the working ranges and the pedal of the hydraulic actuator when the operating speeds are turned on.

Claims (1)

The proposed device consists of a safety mechanism 1 connecting the kinematic linkage pedal mechanism 2 for controlling the hydraulics of the running gear, and mechanism 3 for switching the speed ranges of the gearbox of the vehicle. The speed control of the vehicle is controlled by the pedal mechanism 2 connected to the lever 4 of the valve of the hydraulic pump 5 for driving the driving gear of the drive wheels, through a system of levers 6 and 7 mounted on the intermediate shaft and t 8 and 9. Neutral position of the pedals 10 and 11 corresponds to the neutral position of the valve of the hydraulic pump 5. In this case, the lever 4 is located vertically. The vehicle moves when the pedal 10 or 11 is depressed, while the lever 4 of the hydraulic pump 5 rotates from a vertical position against or clockwise, allowing the vehicle to move forward or backward. The rocker mechanism 3 consists of a scenes 12 operating range switching, the scenes 13 including a transport range, a speed shifter 14 and are kinematically connected with the gearshift control rods. The safety mechanism 1 is made in the form of a pull rod, one end of which ends with a U-shaped clevis 15 with groove B and an anvil 16, an adjusting fork 17 is provided at the other end of the pulling for adjusting the length L In the groove B there is an axis 18 mounted on the lever 19 of the intermediate shaft 20, made with the protrusion 21. The proposed device operates as follows. When the transport speed is turned on (Fig. 2), the knob 14 rotates the slide 13 in the direction of arrow A, moving the safety mechanism 1 behind itself. the vehicle’s forward speed is limited as the axis 18 rests against the left end of the groove B of the U-shaped clevis 15, thus preventing further pedal 10. When you press the raised left pedal And right, the pedal 10 rises, the lever 4 rotates in the opposite direction, the performance of the hydraulic pump 5 decreases, the vehicle speed decreases, and when the pedals are combined, it stops. When the transport speed of the pedal 11 is switched on below the neutral position becomes impossible, as the rocker 13, when rotated by the arrow A, shifts the thrust 8 so that the stop 16 is positioned on the ledge 21. The protrusion 21 is pre-adjusted so that in the neutral position of the pedals 10 and 11, it rests on the anvil 16, which automatically prevents the vehicle from moving backwards when the transport speed is on. Thus, when the transport speed is turned on, the pedal mechanism 2 and the lever 4 of the hydraulic pump 5 associated with it are kinematically closed with the rocker mechanism 3 by means of the safety mechanism 1. When the operating speeds (I, II transmission) are activated, the handle 14 (Fig. 3) turns on backstage 12 working ranges. At the same time, the link 13 of the inclusion of the transport range remains in the neutral position and the safety mechanism 1 does not participate in the work, since the length of the groove B of the U-shaped bracket 1 is longer than the total travel of the axis 18. In this case, the kinematic closure of the pedal mechanism 2 and the hydraulic pump lever 4 does not occur 5 with the rocker mechanism 3. In this case, the safety mechanism 1 does not limit the forward and backward speeds. The invention will improve the reliability of driving and, thereby, increase driving safety. Claims A vehicle control device comprising a hydraulically operated chassis pedal mechanism, having a forward pedal and a reverse pedal, mounted in opposite directions to the intermediate shaft of the mechanism, and a vehicle speed range switching mechanism consisting of the scenes of the inclusion of the transport range, the scenes of the inclusion of the working ranges and the control unit, installed with the possibility of action with said scenes, characterized in that, in order to increase the reliability of driving, it is provided with a safety mechanism, made in the form of a pull-rod with an emphasis, one end pivotally connected to the connecting edge of the transport range and having a longitudinal groove at the other end, which has a slider connected to the said intermediate shaft, made with a protrusion for engaging with the thrust restraint in the transport mode of motion.
