Description

Reversing structure of powered locomotive (2)

The invention relates to the technical field related to locomotive equipment, in particular to a reversing structure of a powered locomotive.

The forward force of the locomotive is powered by the engine, but when the locomotive is about to go backward, the user can only rely on the user's own strength to push the locomotive.

Using manpower to push the locomotive backwards is not a big problem for locomotives with smaller displacements because the overall weight of the locomotive is lighter. However, for heavy-duty locomotives with a large displacement, it is a test of the user's physical fitness.

In order to solve this problem, the motorcycle manufacturer has also proposed a solution. Through the structural design on the new transmission, the user can output power in reverse, so as to facilitate the user to perform the reverse movement of the motorcycle.

Yet this new type speed changer is costly, is not suitable for all kinds of cars, and only new locomotives have the possibility to match, and is all useless for existing all kinds of locomotives. Furthermore, the user needs to go through several switching procedures in the process of operating the new transmission to achieve the change of the power output, which is very troublesome and time-consuming.

In view of the above-mentioned problems and deficiencies of the prior art, the main purpose of the present invention is to provide a reversing structure of a power locomotive, which solves the deficiencies of the prior art through an innovative design of the structure.

According to the above purpose of the present invention, the present invention discloses a power locomotive reversing The retreat structure is set corresponding to the rear wheels of the locomotive, including an internal gear row, a plurality of first pivot seats, a power mechanism, and a clutch mechanism. The inner gear row and the tie ring are arranged on the wheel frame. Each of the first pivot seats is symmetrically locked at the preset position of the vehicle frame. The power mechanism includes a motor pivotally connected with each first pivot seat, and a gear connected in series with the power shaft of the motor. The clutch mechanism is respectively connected with each first pivot seat and the power mechanism, and selectively displaces the external gear to fit or separate from the internal gear row. With the composition of the above-mentioned components, in the fit state, the motor synchronously provides power to drive the inner gear row and the wheel frame connected to it to rotate, and assist the locomotive to perform the reverse movement.
