Embodiment

[0018] front-wheel-drive electric vehicles, such as Figure 1~4 Shown, comprise car body 1, the wheel of car body 1 lower end and the drive axle that is connected between car body 1 front end driving wheel 2 and car body 1; The half shaft 3 between the driving wheel hub 7 and the final reducer, the shock absorbing spring 4 is vertically arranged between the driving wheel hub 7 and the car body 1; Between the stabilizing mechanism, the stabilizing mechanism has three connection points, including a connection point connected to the driving wheel hub 7 and two connection points respectively connected to the car body 1, the three connection points of the stabilizing mechanism form a triangle, Make the driving wheel hub 7 when turning, can limit the driving wheel hub 7 from shaking left and right. During specific implementation, the connection point connected to the hub of the driving wheel is preferably not arranged on the connection position of the half shaft, so as to avoid ove...

Abstract

The invention provides a stabilization mechanism lower supporting arm of a front-wheel-drive electric vehicle convenient to steer. A ball cup is arranged at one end of the lower supporting arm, the upper surface of the ball cup is downwards concaved to form a hemispheric inner cavity, and the diameter of the opening of the inner cavity is smaller than the maximum diameter of the inner cavity. The lower supporting arm further comprises a ball rod vertically arranged, and one end of the ball rod is spherical, embedded into the inner cavity of the ball cup and connected with the inner wall of the inner cavity of the ball cup in a sliding mode. A through hole is transversely formed in the other end of the lower supporting arm and is throughout the side face of the lower supporting arm, the lower supporting arm is connected through a screw in a rotatable mode, the screw penetrates through the through hole of the lower supporting arm, and an anti-slipping gasket is arranged on the inner wall of the inner cavity of the ball cup. The lower supporting arm can be combined with a stabilization mechanism designed by the applicant, and is connected with a drive wheel hub in a rotating mode through rotation connection between the ball rod and the ball cup. The lower supporting arm is simple in structure and convenient to connect with the drive wheel hub and a vehicle body in a rotatable mode, the rotation range is determined through the opening of the ball cup, the opening of the ball cup can be changed according to actual conditions, and using is convenient.

Description

technical field [0001] The invention relates to the field of motor vehicles, in particular to a lower support arm of a stabilizing mechanism of a front-drive electric vehicle that is convenient for steering. Background technique [0002] Existing front-drive electric vehicles include a car body, wheels at the lower end of the car body and a drive axle connected between the front end drive wheel of the car body and the car body; The axle shaft between the vehicle hub and the final reducer, and the shock absorbing spring are vertically arranged between the driving wheel hub and the vehicle body. When turning, the drive axle controls the half shaft to move laterally, thereby driving the driving wheel hub to deflect, thereby realizing the steering function. Because one end of the axle shaft is usually all connected on the side wall of the drive wheel hub, when the drive wheel turns, it usually takes the position in contact with the ground as the fulcrum, and the active forc...
