Abstract
An automatic shift gear for car is composed of speed variator, clutch, pneumatic cylinder, connecting rods, pneumatic electromagnetic valve, slide plate, manual control plate, automatic sensor and main controller, and features that the gear positions can be shifted automatically according to road conditions on car running or manually by means of the buttons on manual control plate. Its advantages include saving fuel and labour, and retaining original manipulating mechanism.
Description
The present invention relates to the transmission device of automobile, especially the clutch gearshift variable part of transmission device.
Automobile is beautiful as the important industry of modern society, the development of its technology is maked rapid progress, people are more and more higher to the various performance requriementss of automobile, the automatic speed changing stepless change of its small and medium-sized car is the direction that people pursue and develop, but the speed-changing mechanism of big-and-middle-sized autotruck is because the dynamics of big its operation of driving force is also big, because of realizing automatic speed changing the compact car than being not easy to resemble, the automatic speed changing car of external full-sized car or stepless speed-varying vehicle can't adapt to our national conditions at present owing to involve great expense comprehensively.
The purpose of this invention is to provide a kind of automatic gearshift for vehicle, make it can widespread use on large-scale autotruck, just give full play to the commonality associativity of prior art and product, make it reach the purpose that makes large-scale autotruck energy autoshift with simple applied in any combination.
The object of the present invention is achieved like this, use the solenoid control air cylinder, piston in the air cylinder links to each other with the speed change lever by rod member, the piston of air cylinder can promote speed change lever gear shift action, the gear that is used for automobile all is more than four, therefore the speed change lever will be in both direction motion in length and breadth, will respectively install a cover air cylinder at vertical and horizontal like this, its air cylinder inner carrier is established two vertex positions and a midway location, midway location is represented with 0, two vertex positions are with ten, an expression is established horizontal air cylinder and is maintained static, and its piston has 0, ten, one or three positions can be respectively make the gear pole pair should horizontal three shelves mouths by connecting rod member.Vertically air cylinder connects the speed change lever equally, and its self-position laterally slides with the speed change lever, its piston 0, ten, one or three positions can enter six gears in front and back respectively to seasonable gang speed-variation lever at three shelves mouths, at vehicle vertical air cylinder when the position is not enough on gear shift cover simultaneously, can guide other position into by the rod member interlock, as long as can finish 0 respectively, ten, one or three are advanced P PARK Position P and get final product, laterally air cylinder can be installed in change speed gear box one side, on its connection rod member movable joint that can swing is arranged, modern autotruck has plenty of with seven gears, just there are four shelves mouths the horizontal position, for satisfying the status requirement of four shelves mouths, can install another horizontal air cylinder in the outside of horizontal air cylinder additional as laterally auxiliary air cylinder, as long as this air cylinder can do ten, one or two position action gets final product, its piston is attached on the previous horizontal air cylinder shell with rod member, just make previous horizontal air cylinder two positions of can whole sliding, so just can satisfy four needs with mouthful vehicle that performs are arranged, the horizontal brake source of the gas of the pneumatic source of air cylinder and vertical air cylinder on can shared car, its operation pressure is consistent with the brake operation pressure of vehicle and will be positioned at brake pressure 0.1 to 0.2 MPa slightly, do not use the vehicle of pneumatic brake that air lift pump and air storage system can be installed on driving engine in addition, the pistons work position of air cylinder is controlled by primary controller by the solenoid control electromagnetic valve, service routine electric-control system in the primary controller, its mode of operation is by the clutch sensor that is contained on the power-transfer clutch, gear position sensor on the change speed gear box, mode of operation automated sensor on driving engine and the transmission shaft and the decision of the manual control panel on the instrument carrier panel, can make the mode of operation autoshift of vehicle like this according to driving engine, also can be according to people's consciousness, use the button gearshift in the manual control panel, the simultaneously complete original operating mechanism of reservation, the work of its power-transfer clutch is by the air cylinder control that is contained on the pedal of clutch, the action solenoid control of its air cylinder, for make power-transfer clutch in conjunction with the time can be soft steadily, between clutch solenoid valve and power-transfer clutch air cylinder, install adjustable damping slow release device additional, the mode of operation of driving engine just rotating speed is added in step motor control on the accelerator rod by the accelerator rod of former car and symbol, and stepping is electronic to be controlled by primary controller.
Automatic gearshift for vehicle by the such scheme formation, it is simple to have combination, the technology maturation cost is low, do not change the manual operation system of former car, make the gear-change operation can automatic guidance, also can handle by hand push button, can make simultaneously engine operation at the best state of exerting oneself, play the car effect of fuel-efficient province,, fault is arranged and in particular cases still can use origin operation mechanism in automatic system because of not changing the manual-operating mechanism of former car, can guarantee the dependable service of vehicle, do not increase the technical risk of chaufeur again, and alleviated the labour intensity of chaufeur, improved the automation of autotruck and driven effect.
The present invention will be further described below in conjunction with Fu Tu and embodiment.
