Abstract
The utility model discloses an automatic switching control system for a braking oil way of an engineering vehicle. The automatic switching control system comprises a central controller, a gear detection device, a switching switch, an oil way switching valve of a braking system and a prompt device, wherein the gear detection device is electrically connected with the central controller; and the central controller is electrically connected with the switching switch, the oil way switching valve of the braking system and the prompt device. The automatic switching control system has the advantages that when the vehicle is in the state of a driving gear, the oil way of the braking system can be started automatically to ensure the safety of driving.
Description
Technical field
The utility model relates to a kind of control system, specifically is a kind of brake circuit automatic switching control system of engineering truck, belongs to technical field of engineering machinery.
Background technology
In the full power hydraulic brake system of engineering truck; The switching of the working connection that brake circuit and rotating oil circuit are come out from Hydraulic Pump by a solenoid control is to be accomplished by a switch direct control electromagnetic valve like existing mode (as shown in Figure 1) in the rough-terrain crane; But; This mode is in the operation of reality; Chaufeur can be because some reason is forgotten to be opened change-over switch or change-over switch is not understood and do not known to open in system, and brake system just can not be worked like this, and is not only influential to the equipment on the vehicle in driving; And threaten the safety of chaufeur itself, this situation of ubiquity all in the present various engineering trucks.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of brake circuit automatic switching control system of engineering truck, when vehicle is in traveling gears, can start the oil circuit of brake system automatically, has guaranteed traffic safety.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of brake circuit automatic switching control system of engineering truck; Comprise central control unit, gear detection device, change-over switch, brake system oil circuit transfer valve and suggestion device; Gear detection device is electrically connected with central control unit, and central control unit is electrically connected with change-over switch, brake system oil circuit transfer valve and suggestion device respectively.
Further, suggestion device is the early warning indicator lamp.
The beneficial effect of the utility model is: the mode that adopts central control unit; If not closed change-over switch;, vehicle also can start the oil circuit of brake system when being in driving states automatically; Can point out chaufeur through suggestion device simultaneously, guarantee the safety of chaufeur, also guarantee the normal operation of equipment.
Description of drawings
Fig. 1 is the electric functional block diagram of prior art;
Fig. 2 is the electric functional block diagram of the utility model.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As shown in Figure 2; A kind of brake circuit automatic switching control system of engineering truck; Comprise central control unit, gear detection device, change-over switch, brake system oil circuit transfer valve and suggestion device; Gear detection device is electrically connected with central control unit, and central control unit is electrically connected with change-over switch, brake system oil circuit transfer valve and suggestion device respectively.
Suggestion device is the early warning indicator lamp.
Work engineering: when the center controller receives the closed signal of change-over switch; Central control unit control brake system oil-way transfer valve is started working; Thereby start the brake system oil circuit,, and do not receive the closed signal of change-over switch if central control unit receives the traveling gears signal that gear detection device transmits; Central control unit control brake system oil-way transfer valve is started working; Start the brake system oil circuit, control suggestion device simultaneously and start working, can point out the chaufeur change-over switch not closed effectively.
Claims (2)
1. the brake circuit automatic switching control system of an engineering truck; It is characterized in that; Comprise central control unit, gear detection device, change-over switch, brake system oil circuit transfer valve and suggestion device; Gear detection device is electrically connected with central control unit, and central control unit is electrically connected with change-over switch, brake system oil circuit transfer valve and suggestion device respectively.
2. according to the brake circuit automatic switching control system of the described a kind of engineering truck of claim 1, it is characterized in that described suggestion device is the early warning indicator lamp.
