Abstract
The utility model discloses a hydraulic-hoisting auxiliary braking device for a sweeper. The hydraulic-hoisting auxiliary braking device comprises a hydraulic hoisting cylinder; the hydraulic hoisting cylinder is connected with a container hoisting operation mechanism, a pressure control valve and a pressure sensor; the pressure control valve and the pressure sensor are simultaneously connected with an ECU (Electronic Control Unit); and the ECU is connected with a sweeper braking system. With the adoption of the hydraulic-hoisting auxiliary braking device provided by the utility model, in the condition that a container is hoisted, unexpected accidents can be avoided by ensuring that the sweeper is braked through the effect of the auxiliary braking device when a driver operates the sweeper, so that the security of the urban sweeper is improved, and the accident occurrence rate is reduced.
Description
Technical field
The utility model relates to automobile technical field, specifically relates to a kind of road-sweeper hydraulic lifting complemental brake system.
Background technology
The field of keeping a public place clean in the city, road-sweeper plays very big effect, and it can be accelerated the speed of keeping a public place clean in the city greatly and reduce the heavy degree of hand labor.But its container is in the lifting process, and the driver is if misoperation is easy to take place security incident, and therefore, there is certain potential safety hazard in existing city road-sweeper when its work.
Summary of the invention
For overcoming the deficiency of prior art; The utility model provides a kind of road-sweeper hydraulic lifting complemental brake system; This device can guarantee to be under the situation of lifting state in the compartment, and in the time of the driver's operation automobile, the work through EBA still can guarantee car brakeing and the accident that do not meet accident; Increased city road-sweeper safety, the incidence of minimizing accident.
The utility model solves the technical scheme that its technical problem adopted:
A kind of road-sweeper hydraulic lifting complemental brake system; Comprise the hydraulic lifting cylinder; It is characterized in that: said hydraulic lifting cylinder is connected with container lifting operating mechanism, pressure-control valve and pressure sensor; Said pressure-control valve, pressure sensor connect Electronic Control ECU simultaneously, and said Electronic Control ECU is connected with the road-sweeper brakes.
The beneficial effect of the utility model is: container lifting operating mechanism and pressure-control valve are controlled the up-down of hydraulic lifting cylinder, thereby control the duty of road-sweeper container; Just there is certain pressure in the hydraulic lifting cylinder when container is opened; The pressure sensor and the automatically controlled ECU that then connect above that will work; Convert pressure signal into electronic signal; Thereby the road-sweeper brakes is played a role, and pressure more greatly then brake force is big more, and complemental brake system does not move when hydraulic cylinder is not worked; The utility model can guarantee to be under the situation of lifting state in the compartment; In the time of the driver's operation automobile; Work through EBA still can guarantee car brakeing and the accident that do not meet accident, has increased city road-sweeper safety, the incidence of minimizing accident.
Description of drawings
Fig. 1 is the principle assumption diagram of the utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model instruction, these equivalent form of values drop on application appended claims institute restricted portion equally.
As shown in Figure 1; A kind of road-sweeper hydraulic lifting complemental brake system; Comprise the hydraulic lifting cylinder; The hydraulic lifting cylinder is connected with container lifting operating mechanism, pressure-control valve and pressure sensor, and pressure-control valve, pressure sensor connect Electronic Control ECU simultaneously, and Electronic Control ECU is connected with the road-sweeper brakes.
When the utility model used, container lifting operating mechanism and pressure-control valve were controlled the up-down of hydraulic lifting cylinder, thereby control the duty of road-sweeper container; Just there is certain pressure in the hydraulic lifting cylinder when container is opened; The pressure sensor and the automatically controlled ECU that then connect above that will work; Convert pressure signal into electronic signal; Thereby the road-sweeper brakes is played a role, and pressure more greatly then brake force is big more, and complemental brake system does not move when hydraulic cylinder is not worked.
The utility model can guarantee to be under the situation of lifting state in the compartment; In the time of the driver's operation automobile; Work through EBA still can guarantee car brakeing and the accident that do not meet accident, has increased city road-sweeper safety, the incidence of minimizing accident.
