Technical Field
The invention relates to an electronic parking brake device for a large-tonnage commercial vehicle, in particular to a central parking brake device adopting an electronic brake mechanism, and provides a scheme for electronic parking brake of the large-tonnage commercial vehicle.
Background
The electronic parking braking technology is more and more popular among automobile manufacturers and consumers because of simple arrangement, small and exquisite control switch structure and multiple value-added functions, and can support intelligent driving and unmanned driving. At present, the electronic parking brake technology is applied to passenger vehicles more generally, but the electronic parking brake technology is applied to commercial vehicles due to the technical scheme and the manufacturing cost, the application range is limited to small-tonnage and high-price commercial vehicles, and the electronic parking brake technology is rarely applied to large-tonnage commercial vehicles. In the existing commercial vehicle electronic parking braking scheme at present: for example, a zip-top EPB (EPB: electronic parking brake system) has the defects of low transmission efficiency of wire drawing force, high after-sale failure rate and the like, is limited by the insufficient clamping force of the current large motor, can only meet the braking requirement of a commercial vehicle within 4.5 tons in technical state, and has high manufacturing cost and smaller application range.
SUMMERY OF THE UTILITY MODEL
The invention aims to overcome the defects of the prior art, adapt to the requirements of practical design and provide a low-cost electronic parking braking scheme for a large-tonnage commercial vehicle.
The invention adopts the following technical scheme:
an electronic parking brake device for a large-tonnage commercial vehicle comprises an integrated controller, an electronic brake mechanism and a brake device, wherein the integrated controller is connected with the electronic brake mechanism.
The integrated controller is provided with a control switch, and the integrated controller is integrated with a vehicle speed signal, an accelerator signal and a gradient sensor.
The electronic braking mechanism is fixedly connected to one end of the output shaft of the gearbox, close to the braking device.
The electronic brake mechanism can adopt two different types of brake mechanisms, namely an electronic caliper or an electronic drum brake.
When the electronic brake mechanism respectively adopts the electronic calipers and the electronic drum brakes as the brake mechanisms, the brake discs and the brake drums are correspondingly used as the brake devices matched with the electronic brake mechanisms.
Has the advantages that:
under the condition of only using one electronic brake mechanism and one brake device, the electronic parking brake device effectively solves the application problem of the electronic parking brake technology of the large-tonnage commercial vehicle, solves the problems of insufficient parking brake force, low transmission efficiency, high after-sale failure rate and the like of the traditional wheel-edge EPB scheme, reduces the manufacturing cost of the device and provides technical support for the large-scale application of the electronic parking brake device in the field of the large-tonnage commercial vehicle due to the brake scheme of unilateral braking.
