Reversing device for in-situ steering of vehicle driven by single engine

Abstract

The invention provides a reversing device for in-situ steering of a vehicle driven by a single engine. The reversing device is characterized by being arranged between an input shaft and an output shaft so that the input shaft and the output shaft can rotate in the same direction or the reverse direction, and composed of a planetary gear train transmission mechanism, a reversing execution mechanismand a reversing operation mechanism, wherein the planetary gear train transmission mechanism is located in the middle of the reversing execution mechanism, and power is transmitted through autorotation or revolution of planetary gears; and in the reversing operation mechanism, a shifting fork is used for shifting movable connectors of the reversing execution mechanism to slide in the axial direction so that the movable connectors can mesh with or be separated from gear teeth on the end surfaces of corresponding reverser shells, and therefore power can be transmitted in the same direction or in the reverse direction in the planetary gear train transmission mechanism. According to the reversing device, the structure is simple and compact, the occupied space is small, and the function of in-situ steering of the vehicle driven by the single engine can be effectively realized.

Description

technical field [0001] The invention belongs to the technical field of vehicle steering transmission, and in particular relates to a reversing device used for in-situ steering of a single-engine-driven vehicle. Background technique [0002] With the development of society, the number of vehicles has increased, urban traffic has become more and more congested, and the space left for vehicles to drive has become smaller and smaller. When the vehicle turns, it often needs to take up a lot of space. Therefore, under the condition of increasingly tight space, it becomes more and more necessary to realize the vehicle turning in situ to reduce the turning space. [0003] In order to realize the turning of the vehicle on the spot, it is only necessary to control the rotation direction of the wheels on the outside of the turn to remain unchanged, and the wheels on the inside of the turn to rotate in the opposite direction. At present, there are "four-wheel steering mechanism" and "d...

Problems solved by technology

[0004] The four-wheel steering mechanism means that the four wheels of the vehicle are driven independently and steered independently. The four wheels can adopt the same structural form, and the four wheels are independently driven by four steering motors. The direction of rotation of the driving motor corresponding to each wheel is enough. This method can improve steering maneuverability, handling stability and driving safety. However, since four sets of driving mechanisms are required to drive independently, no matter the design structure of the steering mechanism or The control process of the steering mechanism is very complicated;

[0005] If the dual-engine driving mechanism is to realize the in-situ steering of the vehicle, an H-shaped transmission structure is required. The vehicle is driven by two sets of power mechanisms to drive the axles on both sides respectively. When the dual-engine driving mechanism drives the vehicle to perform in-situ steering, among them The reverse gear of the gearbox connected to one engine can realize the reverse rotation of one side of the wheel. Compared with the four-wheel steering mechanism, the complexity of this steering transmission mode is slightly reduced. However, the transmission form of this dual-engine drive mechanism , the power system takes up a lot of space, and also has the defect that the control process is relatively complicated
