Partial pendulum and steering mechanism for partial pendulum form vehicle

Abstract

The invention discloses a partial pendulum and steering mechanism for partial pendulum form vehicle, the main vehicle skeleton includes a front support, a main beam, the upper part of the main beam has a top end extended segment, the top end extended segment and the main beam are integrated into one form, a front steering upright column sleeve canister is provided on the top end extended segment, the shaft thread of the front steering upright column sleeve canister and the shaft thread of a shaft bearing groove on the main beam are collinear, a half open form front steering upright column runs through the front steering upright column sleeve canister and the bottom of the half open form front steering upright column and connects with a shaft bearing provided inside the shaft bearing groove, the top end of the half open form front steering upright column is provided with a vehicle handle, the vehicle handle at the side wall of the half open form front steering upright column stretches out a connection rod, the connection rod is connected with a pin shaft in the middle of a universal steering mechanism. The partial pendulum and steering mechanism for partial pendulum form vehicle, with the structure of half open form front steering upright column, makes the main beam have an upward extending space, thereby increases the functional load bearing ability of the main beam, makes the overall structure of the partial pendulum and steering mechanism compact, and lowers production cost.

Description

technical field [0001] The invention relates to a yaw and steering mechanism on a yaw type vehicle. Background technique [0002] The so-called yaw type vehicle refers to a relatively special product in which the front steering wheel train includes two wheels. Compared with the two-wheeled vehicle, one more wheel is in contact with the ground. The unique stability advantages greatly reduce the possibility of riders slipping and falling, and the driving safety is greatly improved compared with two-wheeled vehicles in complex terrain and surface environments. The main difference between the traditional two-wheeled vehicle and the swaying vehicle is the front wheel part. If the front wheel part of the two-wheeled vehicle can be brought into the market in the form of a single device, and it can be compared with the rear wheel and rear frame of the traditional two-wheeled vehicle Partially connected, the handling of ordinary two-wheeled vehicles can be improved at minimal cost. ...

AI Technical Summary

Problems solved by technology

Due to the use of the ring-shaped front steering column, the main beam can only exist in a "C"-shaped structure, and the possibility of the "C"-shaped main beam having an upward extension space is blocked, so that the rear frame designed and installed around the main beam , main steering column and other components are too scattered, and the installation error between each component is large, resulting in that the apex position of the ring-shaped front steering column cannot be an exact value, and the front steering column and the main steering column can only be divided into shaft This makes the structure of the universal steering mechanism more complicated; in addition, because the lower shaft of the circular front steering column penetrates the "C"-shaped main beam, the gap between the left upper rocker arm, the right upper rocker arm and the main beam The hinge can only be connected through the half shaft, which makes the structure between the rocker arm and the main beam more complicated, the number of parts such as bearings increases, the cost is high, and the processing is difficult; at the same time, the yaw and steering mechanism of the above structure is different from the traditional electric When the rear frame is grafted and installed, because the front steering column and the main steering column are of a split shaft structure, the size of the grafted vehicle becomes too large and the structure of the vehicle is not compact
