Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Fig. 1: organigram of the present utility model.
Fig. 2: lateral plan of the present utility model.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, a kind of suspension type electronic accelerator pedal, comprise pallet body 1, described pallet body 1 offers a downward opening groove, the both sides of groove have hole on the same axis, pedal arm 9 is connected with by the adapter shaft 5 through hole in described groove, pedal arm 9 in groove offers the pedal arm groove of a upper end and front end all opening, slide block 6 is provided with in described pedal arm groove, described slide block 6 is provided with spring assembly, described spring assembly is made up of outer spring 7 and inner spring 8, described outer spring 7 is set on inner spring 8, the described slide block 6 touched mutually with spring assembly has the slip recess being matched with outer spring 7 overall diameter, slip recess is provided with the projection being matched with inner spring 8 interior diameter, outer spring 7 and inner spring 8 are placed on slide block 6 in coaxial mode, one end of described spring assembly is abutted against with slide block 6 phase, the other end touches mutually with the front inner wall of groove, the sidewall of described pedal arm groove is provided with tooth bar, the sidewall corresponding to the groove of tooth bar offers a teeth groove, tooth bar is active in teeth groove, the sidewall corresponding to the described groove of tooth bar is provided with the gear 2 be meshed with tooth bar, flat pin on described gear 2 is connected with sensor 3, described sensor 3 is installed on the sidewall of the described groove corresponding to tooth bar 2.
Described pedal arm in groove offers the through hole that is matched with adapter shaft 5, for being flexibly connected mutually with adapter shaft 5, being and being suspended in pallet body 1, this pedal arm 9 can carry out injection mo(u)lding by plastic material, and quality is light; And pedal arm 9 and pallet body 1 and very simple with the assembling of other accessories, production efficiency greatly improves, and assembly cost is low.
Wherein, the sidewall corresponding to the described groove of tooth bar is provided with boss, and gear 2 is active in boss, ensures the normal operation of gear 2, can also prevent gear 2 from departing from the meshing relation with tooth bar, described sensor 3 is installed on boss by thread-forming screw 4 simultaneously.
