Description

Gear selecting and shifting mechanism based on automatic clutch automobile

Technical Field

The utility model relates to an automotive transmission field, concretely relates to select gearshift based on automatic separation and reunion car.

Background

The automatic clutch vehicle is characterized in that a set of independent system is additionally arranged on the basis of the existing manual transmission to control the separation and the connection of a vehicle clutch, so that the effect of 'no stepping on the clutch when driving' is achieved. The application of the automatic clutch on the vehicle greatly reduces the labor intensity of a driver.

In an automatic clutch vehicle control system, one of key links is how to accurately know the automobile gear state and the gear shifting intention of a driver, when a TCU identifies the driving intention of the driver, a controller can combine the current vehicle condition and road condition to control a clutch actuator, so that the clutch is automatically engaged or disengaged, and further the gear shifting and starting are realized.

In order to improve the accuracy of TCU control and the timeliness of response and ensure the quality of gear shifting completion, the TCU needs to monitor the gear where the transmission is located in real time so as to regulate and control the clutch in time. Particularly, in the gear selecting and shifting process, the current gear and the completion state need to be accurately monitored and timely fed back to the TCU.

Sensors for recognizing the driver's intention to shift are mainly arranged on manual shifters in automatic clutch vehicles currently on the market. For example, chinese utility model patent with publication number CN 201245077Y discloses an automobile gear sensor, which accurately locates the position of the upper handle of the manual shifter and feeds back the position to the TCU. Because the gearbox is the final actuating mechanism who selects to shift gears, there is certain deviation between the action of manual gear shifter and the action correspondence of gearbox, though the deviation is very little, still can influence user experience to a certain extent. In addition, because the monitored manual gear shifter is not an actuating mechanism for gear selection and shifting, the monitoring of the manual gear shifter can only reflect the current gear and the gear shifting intention, and the gear shifting process and the gear shifting result cannot be accurately reflected. Moreover, in the scheme, a plurality of conversion parts are arranged in the middle, the gear shifting condition cannot be directly fed back, and the size error is accumulated and is not easy to control.

In order to solve the technical problem, the utility model provides a technical scheme as follows: a gear selecting and shifting mechanism based on an automatic clutch automobile comprises a top cover, a gear selecting shaft and a gear shifting shaft, wherein the gear selecting shaft and the gear shifting shaft penetrate through the top cover and are in sealed connection with the top cover; the gear selecting shaft is connected with a gear selecting arm, and the gear shifting shaft is connected with a gear shifting arm; the gear monitoring device is characterized by further comprising a gear monitoring module, wherein the gear monitoring module comprises a mounting bracket arranged on the top cover, the mounting bracket comprises an inner mounting plate and an outer protection plate, a plurality of support rods are connected between the inner mounting plate and the outer protection plate, and a mounting space is formed between the inner mounting plate and the outer protection plate; the gear monitoring module further comprises a first sensor for monitoring the position and the state of the gear selecting shaft and a second sensor for monitoring the position and the state of the gear shifting shaft, and the first sensor and the second sensor are arranged in the mounting space and connected with the inner mounting plate.

The top cover is additionally provided with a mounting bracket, and a sensor is arranged on the mounting bracket and used for directly monitoring the positions and the states of the gear selecting shaft and the gear shifting shaft. Compared with the traditional mode that a manual gear shifter is used as a monitoring object, the monitoring precision of the current gear, the gear change process and the gear shifting result is higher, and the monitoring result is accurate.

The sensor passes through the installing support setting, and the installing support plays the guard action to the sensor, avoids using and causes the damage to the sensor in the maintenance process, improves life. In addition, the sensor is pre-installed on the installation support and integrally installed on the top cover in the mode of the gear monitoring module, so that the modular production of products is improved, and the installation and maintenance cost is reduced.

Preferably, a plurality of mounting holes are distributed on the top cover; the mounting bracket further comprises connecting arms in one-to-one correspondence with the mounting holes, and the mounting bracket is connected with the top cover through the connecting arms. On original derailleur basis, only need add the mounting hole on the top cap for connect the installing support, it is very little to the change of current structure, can effectual reduction in production cost, can upgrade and reform transform even on current derailleur basis and obtain.

Preferably, the gear selecting shaft is provided with a first positioning pin corresponding to the first sensor, and the gear shifting shaft is provided with a second positioning pin corresponding to the second sensor.
