CN2848654Y - Electric slow speed brake device of automobile - Google Patents

Abstract

The utility model provides an electric retarding and braking device of an automobile, which is composed of an actuating mechanism that is composed of a driving shaft and a brake, and a control mechanism that is composed of a brake chamber connected with an automobile air cylinder, a pressure regulating valve and an electromagnetic valve through a pipeline, wherein the brake is fixedly arranged on the driving shaft through a dust board and a positioning bearing. The two mechanisms are in contact with an adjusting arm of the brake through a post rod of the brake chamber and achieve the process of braking. Vehicle speed is reduced through limiting the rotation speed of the driving shaft, the probability of side slip can be maximumly reduced and the service life of tyres can be prolonged. The utility model has the advantages of simple structure, convenient installation, easy maintenance and low cost, and can be widely used for various large and medium-sized automobiles with frequent braking operation, especially large and medium-sized passenger vehicles and cargo vehicles running in mountain areas all the year round.

Description

The slow brake equipment of auto electric

Technical field: the utility model relates to the slow brake equipment of a kind of automobile.

Background technology: Chinese patent CN2597281Y once disclosed a kind of " automobile electromagnetic retarder brake ", this drg utilizes the electromagnetic coupled technology, one section rotor shaft with propeller-shaft as electromagnetic coupled mechanism, and around this rotor shaft, stator coil and magnetic pole be set, it relies on magnetic field work, slows down the moving velocity of automobile by the rotational resistance torque that produces.Though it can prolong the service life of drg and tire, himself complex structure, installation, maintenance inconvenience is made and the operating cost height, therefore is unfavorable for applying.

The utility model content: task of the present utility model is at the problems referred to above, provides a kind of auto electric slow brake equipment, and it utilizes the electric gentle work of carrying out, and not only simple in structure, cost is low, and installation, maintenance is convenient, and expense is low.Its technical solution is: the slow brake equipment of a kind of auto electric, comprise transmission shaft, drg, and it is characterized in that: said drg is installed on the transmission shaft by dust board and location bearing, constitutes the operating part of this device; In addition, connect brake repair room by pipeline, constitute the control part of this device by automobile air storage vessel, pressure regulating valve, electromagnetic valve; Wherein the push rod of brake repair room touches mutually with the adjusting arm of drg.The utility model comes down to increase a brake point again on the basis of two brake points of original automobile back wheel, but this brake point is not to act directly on the wheel, but act on the transmission shaft, it is to reduce the speed of a motor vehicle by the rotating speed that limits transmission shaft, the probability of breakking away and taking place can be reduced to greatest extent, the service life of tire can be prolonged again.Compared with prior art, the utility model is simple in structure, and installation and maintenance are convenient, manual dexterity, and fault rate is low, and especially cost is low, therefore utilizes and applies.

Description of drawings: Fig. 1 is a structural representation of the present utility model.

The specific embodiment: as shown in Figure 1, the slow brake equipment of the auto electric that the utility model provides, mainly form by two parts, the actuating unit that a part is made up of transmission shaft 3 and drg 1, drg 1 wherein is installed on the transmission shaft 3 by dust board 2 and location bearing.The control mechanism that the brake repair room 4 that another part is being connected by pipeline by automobile air storage vessel 7 and pressure regulating valve 6, electromagnetic valve 5 is formed.These two parts touch the realization braking procedure by the push rod 41 of brake repair room 4 mutually with the adjusting arm 15 of drg 1.Brake strap 13 in the accompanying drawing 1, brake disc 14, adjusting arm 15 and be connected on braking hub 12 end faces and be used for being common brake components with transmission shaft 3 back-connected flanges 11.That is drg here 1, brake repair room 4, air tank 7, pressure regulating valve 6, electromagnetic valve 5 etc. are prior art.The utility model can be regulated the air pressure of brake repair room 4 rightly according to weather and road surface situation in operator's compartment, to give brake strap 13 1 suitable its effective brakings of card of trying hard to keep.The big-and-middle-sized automobile that it can be widely used in the frequent all kinds of compressed air brakes of braking travels at the big-and-middle-sized passenger and freight car in mountain area especially throughout the year.

Claims (1)

1, the slow brake equipment of a kind of auto electric comprises transmission shaft, drg, it is characterized in that: said drg (1) is installed on the transmission shaft (3) by dust board (2) and location bearing, constitutes the operating part of this device; In addition, connect brake repair room (4) by automobile air storage vessel (7), pressure regulating valve (6), electromagnetic valve (5) by pipeline, constitute the control part of this device, wherein the push rod (41) of brake repair room (4) touches mutually with the adjusting arm (15) of drg (1).
