Accelerator wrong stepping correction device with inching clutch

Abstract

The invention discloses an accelerator wrong stepping correction device with an inching clutch and belongs to the technical field of automobile braking. The accelerator wrong stepping correction device comprises a pressure type low-pressure electric switch, a jaw inching clutch and a braking draw cord; a driving tooth-embedded disc of the jaw inching clutch is provided with tooth faces and a separation spring is arranged between tooth faces of a driven tooth-embedded disc, a depressed ring which is in the same plane of the periphery of the driven tooth-embedded disc is arranged at the periphery of the driven tooth-embedded disc, the braking draw cord is embedded into the depressed part of the depressed ring, and two ends of a shell of the tooth-embedded disc are fixedly connected with a low-pressure motor and a low-pressure solenoid valve respectively; one end of the braking draw cord is fixedly connected with the interior of the depressed ring and the other end of the braking draw cord passes through a guide rope hole; and the low-temperature solenoid valve and the low-temperature motor of the jaw inching clutch are connected with the pressure type low-pressure electric switch. The accelerator wrong stepping correction device has the advantages of quick reaction speed for correcting the accelerator wrong stepping behavior, simple structure, small volume, low cost and high reliability and is easy to install.

Description

technical field [0001] The invention belongs to the technical field of brakes for automobiles, in particular to a device capable of obtaining the mechanical action of accidentally stepping on the accelerator and driving the mechanical action of the brake through a micro clutch. Background technique [0002] In his authorized patent 200510022077.X "throttle system device with annunciator", the applicant provides a device that has the ability to judge whether the throttle action is correct or wrong before determining whether to remedy and brake, so that the throttle can be controlled. A motor vehicle accelerator pedal system capable of moving and accelerating. It is characterized in that an annunciator is arranged on any one of the accelerator pedal, the linkage device and the vehicle body device. The annunciator is connected with the electric valve that can cut off the engine oil circuit and the electric valve on the wheel brake. This technology proposes to use electronic s...

Problems solved by technology

The first disadvantage of this technology is that the continuously changing pressure signal sensed by the annunciator is taken out of the misstepped accelerator signal. When the signal acquisition device fails, it may cause errors in the judgment of the misstepped accelerator signal, resulting in poor reliability of the system.

The second disadvantage of this technology is to use the signal output line to control the electric valve, and use the electric valve to control the vehicle's engine oil supply pipe, ignition circuit, motor power supply and other power sources of the vehicle, so that the driver will accidentally step on the accelerator until the vehicle is stopped. Long, the vehicle has a long trip to make an error, and this slow response is not good for preventing traffic accidents.

[0003] In his patent application 201110030092.4 "A Device for Automatically Correcting Misstepped Accelerators to Brakes with Electric Appliances and Machinery", the applicant disclosed a device including a sensor, a signal analyzer and a brake activation mechanism. There are many microelectronic devices for stepping on the accelerator signal, and the reliability is reduced; the second disadvantage is that in the brake starting mechanism, the circular motion of the motor is changed into the reciprocating motion of the brake rope, and the straight rack is used to change the motion mode, because it needs The reciprocating motion of the positioning of the straight rack requires a frame that fixes the relative position of the motor and the straight rack. This frame is bulky and difficult to find a suitable position for installation, and has a complex structure, high cost and poor reliability.
