Abstract
A vacuum booster disc-drum combination type brake of an electro-car servo comprises a vacuum booster pump, a vacuum bag, a handle-type brake device, a pedal brake device, a rubber vacuum pipe, a power-driven vacuum pump, an electronic controller, back wheels, a braking hydraulic pipe, front wheels and a vacuum tank. The vacuum tank is connected with the vacuum bag through the rubber vacuum pipe and connected with the power-driven vacuum pump through a pipeline. The power-driven vacuum pump is connected with the electronic controller through a wire, and the electronic controller is provided with a D C 12 V power source through the wire and a resistor and connected with the electronic controller through the wire. One end of the vacuum bag is connected with the pedal brake device through a connection device and connected with the handle-type brake device and a pawl type parking brake device through a connection wire, and the other end of the vacuum bag is connected with the vacuum booster pump. The vacuum booster pump is connected with the front wheels and the back wheels through the braking hydraulic pipe. The vacuum booster disc-drum combination type brake of the electro-car servo has the advantages of being simple in integral structure, convenient to operate and use, good in stability and high in reliability.
Description
Technical field
The utility model relates to the Brake for vehicle device, relates in particular to the servo vacuum servo dish drum of battery-driven car compound type drg.
Background technology
Present commercially available battery-driven car; Comprise electric two-wheel vehicle, electro-tricycle and electric four-wheel vehicle; And electric golf car, electronic car and the electronic public security scout vehicle browsed, basically all be to have adopted drum brake apparatus, although also have be arranged to band brake type; What have is arranged to expanding brake type, but overall structure still belongs to the drum brake mechanism structure.Generally speaking, drum brake mechanism is the friction that utilizes between the brake shoe lining, and kinetic energy is converted to heat energy and realizes braking.But the heat in the brake wheel also is difficult for distributing, and therefore, in time distributing of heat is its subject matter of guaranteeing braking effect, so that through pulling chain lock and connecting rod mechanism pulling brake equipment; The strength that need apply can be very big, and is weak if navigating mate power is little, perhaps because water inlet in the brake wheel; Drum brake mechanism all can not produce the actv. braking, just can not realize that also actv. stops, and is especially fully loaded at the load-carrying battery-driven car, perhaps water inlet in the brake wheel; When the battery-driven car cruising, and run into emergency situation suddenly, this emergency brake is very difficult; Even can check, also to skid off several meters, even tens meters.If meet water inlet in the brake wheel, cause brake failure possibly, thereby cause hardly imaginable serious consequence.
The utility model content
The purpose of the utility model is, overcomes the weak point of prior art, and the servo vacuum servo dish drum of a kind of battery-driven car compound type drg is provided, and guaranteeing is needing under the situation of drag, accurately realizes drag on demand, guarantees the safety of driving a vehicle.
The servo vacuum servo dish drum of the described battery-driven car of the utility model compound type drg includes vacuum booster pump, vacuum packet, wushu brake gear, pawl type holding brake device, footbrake device, rubber vacuum lamp, electric vacuum pump, resistance, electronic controller, trailing wheel, brake fluid pressure pipe, front-wheel and vacuum reservoir.Vacuum reservoir is the vacuum closed-center system of the utility model; Be connected with vacuum packet through the rubber vacuum lamp on the vacuum reservoir; Vacuum reservoir is connected with electric vacuum pump through pipeline; Electric vacuum pump is connected with electronic controller through circuit, and electric controller is provided with the DC12V power supply through circuit and resistance, and electronic controller is connected to vacuum reservoir through circuit again.One end of vacuum packet is connected with the footbrake device through connecting device, also is connected with wushu brake gear and pawl type holding brake device through connection lead simultaneously.The other end of vacuum packet is connected to vacuum booster pump, and vacuum booster pump is connected to trailing wheel and front-wheel through the brake fluid pressure pipe respectively.
The servo vacuum servo dish drum of the described battery-driven car of the utility model compound type drg, integral structure is simple, and is easy for operation, good stability, reliability is high.Use the servo vacuum servo dish drum of the described battery-driven car of the utility model compound type drg, can guarantee is needing under the situation of drag, accurately realizes drag on demand, the safety with Parking of guaranteeing to drive a vehicle.
Description of drawings
Accompanying drawing 1 is the structural representation of the servo vacuum servo dish drum of the said battery-driven car of the utility model compound type drg.1-vacuum booster pump, 2-vacuum packet, 3-wushu brake gear, 4-pawl type holding brake device, 5-footbrake device, 6-rubber vacuum lamp, 7-electric vacuum pump, 8-resistance, 9-electronic controller, 10-trailing wheel, 11-brake fluid pressure pipe, 12-front-wheel, 13-vacuum reservoir.
