Embodiment 1

[0024] Such as figure 1 and 2 As shown, a two-way return mechanism of the accelerator pedal is suitable for the accelerator mechanism of vehicles with driving forward and backward functions such as lawn mowers, floor washing machines, ATVs, UTVs, and golf carts. It can also be applied to the accelerator mechanism of electric scooters, electric tricycles, four-wheelers, old scooters, electric vehicles and other slow road electric vehicles.

[0025] The drive shaft 1 has a built-in toggle sensor for sensing the direction of rotation and the range of rotation, and the drive shaft 1 is fitted with a flanged nylon sleeve 2 to increase wear resistance and reduce noise.

[0026] The forward pedal assembly 3 includes: a shaft hole 31 for matching the drive shaft, a pedal end on one side of the shaft hole 31, and a shift fork end 32 on the other side of the shaft hole 31; with the shaft hole 31 as the rotation center, the pedal end is located on the top side, the shift fork end 32 is...

Embodiment 2

[0033] Such as figure 2 shown.

[0034] 1. The first pull plate 6 and the second pull plate 7 are installed through some reinforced iron pads 10 and nylon pads 11 with wear-resisting and noise-reducing effects, and then installed on the forward accelerator pedal assembly by a circlip 12 for the shaft. On the outer circle of the shaft tube 31 of 3, the two pull plates have no displacement function in the axial direction, and can only rotate freely in the circumferential direction.

[0035] 2. Assemble the assembled semi-finished product to the inside of the external bracket 13, insert the flange nylon bushing 2 and the drive shaft 1 from the outside through the external bracket 13 into the shaft tube 31 of the forward accelerator pedal total 3, and then use a The stepped bolts 33 pass through the axle tube 31, the flange nylon bushing 2, the drive shaft 1, and then the flange nylon bushing, then the axle tube passes through, and lock the nut 34. The flange nylon bushing 2, t...

Abstract

The invention discloses a bidirectional return mechanism of an accelerator pedal. The bidirectional return mechanism comprises a forward pedal assembly, a backward pedal and a driving shaft; one end of the driving shaft is a forward pedal assembly, and the other end is a backward pedal; a first pull plate and a second pull plate are also sleeved on the forward pedal assembly; the first pull plateand the second pull plate are connected through a tension spring; and the advancing pedal assembly comprises a shaft hole used for being matched with the driving shaft, a pedal end on one side of theshaft hole and a shifting fork end on the other side of the shaft hole. A limiting part for limiting the pull plate to swing is arranged between the first pull plate and the second pull plate; the shifting fork end swings along with the pedal end and shifts the first pull plate or the second pull plate; the first pull plate rotates along with the forward pedal assembly, the limiting part abuts against the second pull plate, and the tension spring deforms and provides reset tension for the first pull plate; and the second pull plate rotates along with the rear pedal, the limiting part abuts against the first pull plate, and the tension spring deforms and provides reset tension for the second pull plate. According to the structure, the use of mechanical gears is reduced, and parts are reduced, so that the occurrence of problem points is reduced.

Description

technical field [0001] The invention relates to the field of transmission and speed change structures, in particular to an accelerator pedal bidirectional return mechanism. Background technique [0002] The driving of most vehicles requires neutral gear and switching between forward and backward. There are mainly the following schemes to support: 1. Operate the clutch to switch between front-empty-rear gears; 2. Operate the electronic gear switch to switch the electric vehicle Front-empty-rear gear switching. [0003] These gear switching modes are mostly found on fast-moving vehicles, and their structures are relatively complicated and the cost is too high. And for some slow-moving equipment and vehicles, more practical gear switching structures are needed. It cannot meet the control requirements and is suitable for most mechanical structural arrangements. The transmission process does not need to be cumbersome, but it needs to respond in a timely manner, meet the needs ...
