Embodiment Construction

[0024] like figure 1 As shown, the engine high-torque transmission device of the present invention includes a gear assembly 1, a transmission claw assembly 3, and a transmission cover 4. The gear assembly 1 is engaged with the gear of the engine, and the gear assembly 1 is installed on the front end of the crankshaft of the air compressor 2 to control air compression. The engine 2 is running, and at the same time, the operation of the electronic fuel injection pump 5 and the timing phase angle are controlled by the transmission claw assembly 3. The transmission cover 4 connects the air compressor 2 and the electronic fuel injection pump 5 to form a sealed cavity, and the transmission claw assembly 3 is sealed in the In the cavity, lubricate and protect the transmission claw assembly 3.

[0025] like figure 2 As shown, the gear assembly includes bolts 6, gear platen 7, air compressor gear 8, and gear seat 9. The air compressor gear 8 is installed on the gear seat 9 through fo...

Abstract

The invention discloses a large-torque driving device used for an engine. The driving device comprises a gear component, driving pawl components and a driving cover, wherein the gear component is engaged with a gear system of the engine; through gear driving, the gear component drives an air compressor; the air compressor drives an electronic fuel injection pump through the drive pawl components; the drive pawl components are respectively arranged on the shaft of the air compressor and the shaft of the electronic fuel injection pump; through the engagement of two driving pawls, the air compressor drives the electronic fuel injection pump to rotate; and the driving cover is used for sealing and lubricating the driving pawl components and simultaneously supporting and positioning the installation of the electronic fuel injection pump. The large-torque driving device has the advantages of simple structure, driving torque up to 570N.m, and high reliability, can adjust a timing phase angle of the electronic fuel injection pump, and can be widely used in the field of manufacturing engines of which the emission is up to over national standard 3.

Description

technical field [0001] The invention relates to a high-torque transmission device for an engine, in particular to a transmission device for an electronic fuel injection pump for an engine whose emission reaches national standard 3 or above. Background technique [0002] At present, the fuel injection pump used by the engine whose emission reaches the national standard 2 is a mechanical fuel injection pump. To meet the emission of the engine reaching the national standard 3 and above, the mechanical fuel injection pump must be replaced by an electronic fuel injection pump. The peak torque of the electronic fuel injection pump reaches 520N·m. The transmission device of the fuel injection pump cannot meet the torque requirements of the electronic fuel injection pump, and the transmission device of the electronic fuel injection pump cannot be directly used for the requirements of refitting the mechanical fuel injection pump to the electronic fuel injection pump. The fuel injecti...
