Rear axle swing device of three-wheeled motor vehicle

Abstract

The invention relates to a rear axle swing device of a three-wheeled motor vehicle or a three-wheeled diesel motor vehicle. In the rear axle swing device, an end cover of a connecting frame is in positioning connection with a cylinder body, the other end of the cylinder body is in positioning connection with a rear end cover, the end cover and the rear end cover are respectively provided with a bearing supporting a swinging shaft; a circular plate capable of rotating in the cylinder body is fixed at an end part of the swinging shaft near the end cover, two arc damping springs are arranged between the end cover and the circular plate, and a spring shifting block and a spring stop block are respectively arranged between ends of an upper part and a lower part of the two arc damping springs; a sector rack is fixed on the swinging shaft arranged between the circular plate and the rear end cover, a dowel engaged with the sector rack is arranged in a self-locking box which is fixed outside the cylinder body, top end of the dowel firmly props against a sector cam capable of swinging around a pin shaft, and the sector cam is hinged with ends of a self-locking tie bar. The rear axle swing device causes the a rear axle to be capable of swinging up and down relative to a vehicle frame, swinging side to side around a central shaft of the vehicle frame and balancing centrifugal force generated by the vehicle in turning, thus avoiding potential safety hazard of vehicle rollover.

Description

technical field [0001] The invention relates to a component matched with a three-wheel motor vehicle frame, in particular to a rear axle swing device for a three-wheel motor vehicle, which is suitable for a three-wheel electric vehicle or a three-wheel internal combustion motor vehicle. Background technique [0002] The connection between the rear axle and the vehicle frame of the existing three-wheeled electric vehicle or three-wheeled internal combustion motor vehicle makes the rear axle only swing up and down relative to the vehicle frame, and cannot swing left and right around the central axis of the vehicle frame; when the vehicle turns, the vehicle frame cannot Tilt to the turning side to balance the centrifugal force generated when the vehicle is turning, which is very prone to safety accidents of rollover, especially when driving at high speed, this safety hazard is more prominent. When the vehicle is running on a bumpy road, the vehicle frame and passengers will swa...

[0002] The connection between the rear axle and the vehicle frame of the existing three-wheeled electric vehicle or three-wheeled internal combustion motor vehicle makes the rear axle only swing up and down relative to the vehicle frame, and cannot swing left and right around the central axis of the vehicle frame; when the vehicle turns, the vehicle frame cannot Tilt to the turning side to balance the centrifugal force generated when the vehicle is turning, and it is very prone to safety accidents of rollover, especially when driving at high speed, this safety hazard is more prominent

When the vehicle is driving on a bumpy road, the frame and passengers will also sway from side to side, which will affect the comfort of the ride; if there is a large pothole, it is also very prone to rollover safety accidents
