Special executive component for range transmission automobile manual semi-automatic dual-purpose drive control system

Abstract

The invention relates to a special executive component for a range transmission automobile manual semi-automatic dual-purpose drive control system. The special executive component mainly comprises a dual-purpose drive switching device, an automatic accelerator, a hand brake, a selected track, a shifting gear and a clutch executive component device. The output end of a sensor of each executive component is connected with the input end of the system, the output end of the system is connected with the input end of a direct-current stepping motor driver or a relay, the output end of the driver or the relay is connected with a fire wire and an earth wire of a direct-current motor of each executive component, the automatic accelerator, the hand brake, the selected track, the shifting gear and the output shaft of a direct-current stepping motor of the executive component or a direct-current motor with a gear reducer are connected with a ball screw in a machine body through a coupler, flange sleeve screw holes on the ball screw are connected with one ends of hose steel wire ropes of each executive component respectively, a gear on a spindle of a direct-current motor with a worm reducer of an automatic clutch is connected with one end of a chain, the special executive component which moves automatically under the regulation and control of an electronic control unit (ECU) of the system is composed, and the special executive component is simple and general in structure and saves oil and energy.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a special actuator for a manual and semi-automatic dual-purpose driving control system of a stepped transmission automobile. Background technique [0002] Some cars and most trucks today are not equipped with automatic transmissions. Regardless of whether it is a manual transmission car or an automatic transmission car, the accelerator and hand brake still need to be manually operated by the driver based on experience, so that the control of the accelerator and the change of the vehicle speed cannot be optimally matched, and the hand brake is only used as an auxiliary brake. underutilized. When the driver judges by experience that the hand and foot of the accelerator, clutch, and gear lever are not coordinated at the time of shifting, step on the accelerator, clutch, and manually dial into the gear, so driving the car must vary from person to person, and it is...

Problems solved by technology

When the driver judges by experience that the hands and feet of the accelerator, clutch, and gear lever are not coordinated at the time of shifting, step on the accelerator, clutch, and manually dial into the gear, so driving the car must vary from person to person, and it is impossible to use it every time. Operate in the best way, which directly affects the smoothness of the transmission and the stability of the car, so fuel consumption
