Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, described in be to explanation of the present utility model instead of restriction.
The utility model one band odd-side speed changer high to low gear changeover protection system, as shown in Figure 1,2 and 3.It comprises the air valve 8 controlling the conversion of auxiliary box cylinder high to low gear, is connected to the handball 4 of air valve 8 control end, and is arranged on handball 4 and is connected Controlling solenoid valve 6 on tracheae with air valve 8; The inlet end of handball steam outlet pipe 5 connection control solenoid valve 6; The control tracheae 7 that Controlling solenoid valve 6 outlet side connects connects the control end of air valve 8; The inlet end of air valve 8 is communicated with air bag with car load gas circuit 1 by connection tracheae 2, threeway successively; Another branch road of threeway is connected with the inlet end of handball by handball suction tude 3; The control end of Controlling solenoid valve 6 connects ECU module 14 output terminal, and ECU module 14 for the train signal of collection vehicle, and judges driving conditions state.Two output terminals of air valve 8, respectively by low gear tracheae 9 and high gear tracheae 10, are communicated with low gear district 13 with the high gear district 12 of auxiliary box cylinder.Main gas circuit in threeway is for connecting car load tracheae 1 and being connected tracheae 2.
Wherein, the input end of ECU module 14 accesses the vehicle speed signal that clutch switch signal, handball steam outlet pipe ventilation signal and vehicle speed sensor export respectively.When ECU module 14 detects transmission for vehicles in high gear district, ECU module 14 output solenoid valve standby signal; Controlling solenoid valve 6 keeps off state.When ECU module 14 detects transmission for vehicles in low gear district, ECU module 14 output solenoid valve ventilation signal; Controlling solenoid valve 6 action is converted to open mode, controls the low gear state that the normal switching motion of air valve 8 ensures auxiliary box cylinder.When ECU module 14 detect vehicle be in speed to mate with high gear district and lower speed changer by high gear district to carry out to low gear district gear change time, ECU module 14 output solenoid valve inhibit signal; Controlling solenoid valve 6 keeps off state.
The utility model is train signal by ECU module 14 collection vehicle and judges driving conditions state; In deterministic process; main to the speed of a motor vehicle, clutch separation and electromagnetic valve gas circuit make-and-break status information in driving conditions; namely handball steam outlet pipe ventilation signal gathers; and these image data are processed, judged; for protective system work provides basis for estimation; and the collection of data and corresponding process and judgement are the prior art of ECU module 14, what operate respectively by difference output signal and Controlling solenoid valve 6 correspondingly realizes control to air valve 4 and operation.
Concrete working procedure is as follows.
(1) if Fig. 1 is when gearbox is in the conversion of high gear district, now handball shifting block is in high gear position, gear scope is still in neutral at high gear district, main tank.From air bag air by car load tracheae 1 through threeway be connected tracheae 2 and enter air valve 8, a road gas gives handball 4 air feed through threeway by handball suction tude 3 simultaneously, because handball shifting block is still in high gear, therefore do not have gas by handball steam outlet pipe 5 to solenoid valve 6 air feed, ECU module 14 is to the speed of a motor vehicle gathered, clutch separation and handball steam outlet pipe ventilation signal analysis control Controlling solenoid valve 6, it is made not control air valve 8, air valve 8 normal open ensures gas by high gear tracheae 10 to cylinder high gear air feed, the inflation of auxiliary box cylinder high gear district 12 ensures that auxiliary box synchronizer is still in high gear.
(2) if Fig. 2 is when gearbox is in the conversion of low gear district, now handball shifting block is in low gear position, gear scope is still in neutral at low gear district, main tank.From air bag air by car load tracheae 1 through threeway be connected tracheae 2 and enter air valve 8, a road gas gives handball 4 air feed through threeway by handball suction tude 3 simultaneously, because handball shifting block is still in low gear, gas passes through handball steam outlet pipe 5 to solenoid valve 6 air feed, now obtain automobile by vehicle speed sensor and be in lower-speed state, and obtained driver do not carried out high to low gear conversion by clutch switch signal and handball steam outlet pipe signal of ventilating, ECU module 14 is to the speed of a motor vehicle gathered, clutch separation and handball steam outlet pipe ventilation signal analysis control Controlling solenoid valve 6, therefore solenoid valve 6 still controls air valve 8, air valve 8 is often changed to make gas by low gear tracheae 9 to cylinder low gear air feed, the inflation of auxiliary box cylinder low gear district 13 ensures that auxiliary box synchronizer is still in low gear.
(3) as Fig. 3 when speed to be mated with high gear district and lower gearbox is changed to low gear district by high gear district, now handball shifting block transfers low gear to by high gear, main tank is in neutral, clutch switch is opened.From air bag air by car load tracheae 1 through threeway be connected tracheae 2 and enter air valve 8, a road gas gives handball air feed through threeway by handball suction tude 3 simultaneously, because handball shifting block transfers low gear to by high gear, therefore have gas by handball steam outlet pipe 5 to solenoid valve 6 air feed, now obtaining automobile by vehicle speed sensor is at a high speed, namely its speed is mated with high gear district, and prepare to carry out high gear conversion low gear by clutch switch signal and handball steam outlet pipe ventilation signal driver, ECU module 14 is to the speed of a motor vehicle gathered, clutch separation and handball steam outlet pipe ventilation signal analysis control Controlling solenoid valve 6, solenoid valve 6 is got involved but air valve 8 is not controlled, ensure air valve 8 normal open and make gas enter auxiliary box cylinder high gear district 12 by high gear tracheae 10, high gear district 12 inflates and ensures that auxiliary box synchronizer is still in high gear.Gearbox gear keeps high gear, and then protects auxiliary box synchronizer.
By above protective system; utilize existing signal as judgment standard; by control and the access of Controlling solenoid valve 6; can ensure that system is not intervened driving behavior when driver's normal running, in the higher speed of a motor vehicle time carry out high gear and switch in this driving procedure of low gear and carry out interventions and keep auxiliary box synchronizer to be still in high gear position, realize the protection to being with odd-side speed changer.
